Mileage tracking for small business

Yes, if you own it alone and report it on Schedule C: your business miles go on line 9, at the IRS standard mileage rate (72.5¢ a mile through June 30, 2026, 76¢ from July 1) or as the business share of the vehicle's running costs, such as gas, repairs and insurance, plus business parking and tolls. Three limits apply: the drive between home and your regular place of work is commuting and doesn't count unless a home office is your principal place of business, you need a record of each business drive kept as you go, and the mileage rate is open to a vehicle you own only if you used the rate for its first year in your business. You don't need an LLC for it. The total lowers the profit you're taxed on; it isn't money back (Schedule C, line by line).

You don't need an LLC: a business you own alone is a sole proprietorship and files Schedule C, and so does a one-owner LLC unless you chose to have it taxed as a corporation. A married couple who run it together, file a joint return and both materially participate (take part regularly and substantially) can choose to be a qualified joint venture, so each files a Schedule C for their share, but only if the business isn't an LLC or another state-law entity; otherwise two owners, a two-member LLC included, are generally taxed as a partnership unless they chose otherwise, and the business's costs go on the partnership's return, not on a Schedule C of yours (couples in community property states have rules of their own). If you work in your own S corporation, the IRS treats you as its employee, so the usual route is for the corporation to pay you back for business miles under an accountable plan, and that payment isn't income to you. Either way the same mileage log backs the numbers; set it up with your accountant.

Pay their business miles back under an accountable plan: they show you the miles and return anything paid over, and the payment isn't income to them. An employee can't deduct driving the employer doesn't pay back on a federal return, and the 2025 tax law made that permanent, apart from a few named groups (IRS Notice 2026-10). In OdoTax each employee keeps a log in an account of their own, and a report made with your rate per mile prints as a mileage reimbursement claim. Set the plan itself up with your accountant (who can use the business rate).

Only the drives for your own business, and the rules for the first and last drive of the day apply to it on its own. The drive from home to your employer never counts, and a home office for the business doesn't change that, because the home office rule covers only drives in the same business. A drive straight from your day job to the shop or a customer does count: Publication 463 lets you deduct “the expense of getting from one workplace to the other.” Nobody withholds tax from what the business earns, so you may need to pay estimated tax or have more withheld at your job (the home office rule).

Not by itself: losses that are “normal in the startup phase of your type of business” are one of the facts the IRS weighs, and “No one factor alone is decisive.” The tax code also assumes an activity is run for profit if it made a profit in at least 3 of the last 5 years, the current one included, and they needn't be in a row; missing that count doesn't make it a hobby, it only means that rule doesn't help you. The answer matters most in a year like this, because a business loss on Schedule C can lower the tax on your other income, such as wages, within limits (the at-risk rules, for one, generally let you claim a loss only up to what you could actually lose in the business), while a hobby's loss can't be used against other income. So keep what shows you're working to make it pay: contracts, invoices, marketing, prices you changed, and the mileage log. If it has run at a loss for several years, talk to a tax preparer before you claim the miles.

Yes, the profit is taxable however small it is: income tax is figured on it with the rest of your income, and self-employment tax is owed once your net earnings from self-employment reach $400 for the year. Both come after costs, and on a small business the car is often the biggest one. Say the business brought in $6,000 and your only cost was 2,000 business miles in the fall: at 76¢ a mile that's $1,520, which leaves $4,480 of profit. Self-employment tax is then $4,480 × 92.35% × 15.3% = $633.00, against $847.77 without the miles, $214.77 less, and income tax can fall too, by up to the rate your last dollar is taxed at, depending on the rest of your return (what changes at tax time).

The drives you make for the business: from the shop to a supplier or a wholesaler, deliveries and pickups for customers, visits to a customer's place, and the drives from one of those stops to the next. Publication 463 counts “Getting from one workplace to another in the course of your business or profession” and “Visiting clients or customers,” and its example of business use includes meeting suppliers and picking up and delivering items to clients. Driving for yourself or your family is personal, and home to your shop or office is commuting unless your home office qualifies. Name the customer or the errand in each drive's purpose (“business” is not a purpose).

Yes, if the shop is your regular place of work and your home office doesn't qualify: home to the shop and back is commuting “no matter how far your home is from your regular place of work,” and parking there is a commuting cost too. The shop helps with everything else: drives from it to a supplier or a customer count, and so does home straight to a temporary work location, such as a customer's place for one job, and back. The owner in this page's example drove 3,100 miles between home and the shop in 2026; they stayed out of the $3,779.50 on line 9 and went on line 44b. If you do the ordering and the books at home in a space used only for the business, and not at the shop, the home office can be your principal place of business, and then home to the shop counts too (three cases, side by side).

It can, if your home is the business's principal place of business. Publication 587's test: you use a specific area “exclusively and regularly for administrative or management activities” of the business, such as billing, keeping the books, ordering supplies and setting up appointments, and you have “no other fixed location where you conduct substantial administrative or management activities.” A shop where you serve customers or keep stock doesn't count against it, but an office at the shop where you do that paperwork does. When your home qualifies, the shop is another work location of the same business, and home to it counts. Whether yours does is for you and your tax preparer; this is general information from Publication 587, not tax advice (the home office test).

The drive from the supplier on to the shop does: it is between two business stops. The first leg, from home to the supplier, is the harder one. Publication 463 lets you count the drive from home to a temporary work location when you have a regular workplace, and to any work location of the business when your home office qualifies, but it doesn't say whether a quick stop at a supplier is a work location. Log the drive as it was, with a purpose that names the stop, and ask your tax preparer how to treat that first leg.

A supply run does on Publication 463's own words: its example of business use is a car used to “meet with suppliers and other subcontractors, and pick up and deliver items to clients.” The bank and the post office aren't named, so those runs rest on the general test that a business cost is ordinary and necessary in your line of work, with a purpose you can write down, such as “Bank deposit, Saturday takings” or “Posted orders.” From the shop, the round trip is between business stops; a stop for yourself at the same place, such as your own banking, isn't business. For anything you're unsure of, ask your tax preparer.

A lunch stop doesn't break it: Publication 463 says “Minimal personal use, such as a stop for lunch on the way between two business stops, isn't an interruption of business use.” A real detour is different: if for a personal reason you don't go straight from one stop to the next, you “can't deduct more than the amount it would have cost you to go directly,” so count the direct route's miles. OdoTax records the drive as you drove it and can't shorten a recorded drive's miles, so for a detour, write the direct route's miles in the drive's note, which goes into the report's CSV, for your tax preparer (round trips and routes).

No. Publication 463: “Hauling tools or instruments in your car while commuting to and from work doesn't make your car expenses deductible”; only an extra cost of hauling them, such as renting a trailer, is. Advertising on the car “doesn't change the use of your car from personal use to business use,” and taking client calls on the way doesn't either. A drive is business because of where you're going and why, and the log has to say why (tools in the back).

Your own car's business miles count wherever the work is, priced on line 9 like any other drive, and a day trip to a customer or a supplier outside your metro area counts from your driveway and back, even with no shop or home office that qualifies. Staying overnight makes it travel: you're “traveling away from home” when the work keeps you away from the general area of your tax home (generally your regular place of business, or, if you have none, possibly where you regularly live) “substantially longer than an ordinary day's work” and you need sleep or rest, and then the hotel and airfare go on line 24a and meals on line 24b, generally at 50%. If the trip is mainly for the business and you stay on for a vacation, getting there and back still counts but the extra days' costs don't, and someone who comes along, such as your spouse, counts only if they're your employee or a business associate, such as a client or a supplier, with a real business reason to be there. In OdoTax a flight never becomes a drive, and the drives to and from the airport are recorded like any other; Airport / travel is one of the purposes it starts you with. A trip abroad has more rules, in Publication 463, chapter 1, so ask your tax preparer (where travel goes on Schedule C).

Schedule C, Profit or Loss From Business, is the part of your federal return where a business you own by yourself reports what it took in and what it cost; what's left is the profit that income tax and self-employment tax are figured on. Your car shows up on it twice: what its business miles come to on line 9, Car and truck expenses, and its use in Part IV, Information on Your Vehicle (when it went into business use, and its business, commuting and other miles). You don't have to itemize: business miles come off your profit, which carries over to your Form 1040 through Schedule 1, so you can take the standard deduction as well. Itemizing matters only for medical and charity miles (Schedule C, line by line).

It's one IRS amount per business mile that stands in for what the car costs to run: for 2026, 72.5¢ for drives through June 30 (Notice 2026-10) and 76¢ for drives from July 1 (Announcement 2026-11), raised because fuel prices went up. Each drive gets the rate for its own date: the shop owner in this page's example drove 2,300 business miles before July 1 and 2,500 after, which come to 2,300 × $0.725 + 2,500 × $0.76 = $3,567.50, and with $212 of business parking and tolls, $3,779.50 on line 9. OdoTax prices every drive by its date, so the two halves add up on their own (the 2026 rates).

No: a deduction lowers the profit you're taxed on, and the dollar amounts OdoTax shows on your drives are that deduction, not cash. On Schedule C it lowers self-employment tax by about 14¢ for every dollar deducted (15.3% on 92.35% of profit), which at 76¢ a mile is about 10.7¢ a mile, as long as your wages and self-employment earnings together stay under $184,500 for 2026; above that, only the 2.9% Medicare part is left. For the shop owner in this page's example, with $3,779.50 on line 9, that's $3,779.50 × 92.35% × 15.3% = $534.03 less self-employment tax. Income tax falls too, by up to the rate your last dollar is taxed at, and what that adds up to depends on your whole return, so OdoTax shows the deduction, not a saving (deduction or refund).

Usually, if you expect to owe $1,000 or more for the year after withholding and refundable credits, because nobody takes tax out of what the business earns. For 2026 the payments are due April 15, June 15 and September 15, 2026, and January 15, 2027; they cover income tax and self-employment tax, both figured on profit after costs, so an up-to-date mileage log keeps the estimate right. If the business is seasonal, the annualized income installment method can figure each payment from what you had earned by the end of March, May or August, and the whole year for the last; you use it with Form 2210 and Schedule AI, filed with your return. If you also have a W-2 job, extra withholding there counts as paid evenly through the year, whenever it was taken out (quarterly estimated taxes).

Yes: Publication 463's own example is a car used for clients and suppliers that “you and your family use ... for personal purposes,” and on the standard rate you simply deduct the business miles. Only your business drives need the four facts (the date, where you went, why and the miles), but Schedule C, Part IV also asks for the car's total miles for the year, everyone's driving included, split into business, commuting and other; the odometer on January 1 and December 31 is the simplest proof. The date on line 43 is the day the business started using the car, not the day you bought it, and that first year is when the mileage rate has to be chosen. OdoTax records only the drives your phone is on, so your partner's drives without you aren't in it (the readings cover them), and a ride along to soccer practice is recorded for you to mark Personal. Don't sign a family member's phone in to your account: every drive it's on would land in your log and your free count (Part IV, line by line).

No: in a year you use the standard rate, Publication 463 says you “can't deduct depreciation, lease payments, maintenance and repairs, gasoline (including gasoline taxes), oil, insurance, or vehicle registration fees,” because the rate covers them, and 35¢ of each 2026 business mile counts as the car's depreciation. Of a car payment, only the interest goes on top, at the business share, and so does the business share of state and local personal property tax on the car. Business parking and tolls are added at what you paid, but parking at your own shop is a commuting cost, and a parking ticket never counts. Keep a receipt for any parking fee or toll of $75 or more, and the car's purchase papers; there are no fuel or repair receipts to keep (what the rate covers).

Where both are open to you, Publication 463 suggests you “figure your deduction both ways to see which gives you a larger deduction”: the standard rate is business miles times the rate for each drive's date, and actual expenses are the business share (business miles divided by total miles) of what the car really cost, with receipts. The timing matters more than the choice: for a car you own, the standard rate has to be used in the first year the car is available for use in your business, after which you can use either method each year, but a car started on actual costs can never use the rate. A car on which you claim section 179 or the special depreciation allowance (often called bonus depreciation) in its first year can never use it either, so make that choice for a van or truck bought for the business with your tax preparer. A leased car on the standard rate stays on it for the whole lease. Either way you need the mileage log (standard rate or actual expenses).

Each needs its own figures: Publication 463's Table 5-1 asks, for each car, for “the cost of the car and any improvements, the date you started using it for business, the mileage for each business use, and the total miles for the year,” and the Schedule C instructions say “If you used more than one vehicle during the year, attach a statement with the information requested in Schedule C, Part IV, for each additional vehicle.” In OdoTax each vehicle keeps its own log and odometer readings: on Android, link each vehicle's Bluetooth; on an iPhone, pick its CarPlay or Bluetooth stereo, and a drive that starts while the phone plays through it goes on that vehicle. Any other drive goes on your default vehicle, and you can change it under Vehicle on the drive (two vehicles, two logs).

Not while five or more are in use at the same time: Publication 463 says you can't use the standard mileage rate if you “Use five or more cars at the same time (such as in fleet operations).” Then the deduction is the business share of each vehicle's actual costs, and each one still needs its own mileage log. Vehicles used at different times aren't in use at the same time: in Publication 463's examples, a salesperson who takes turns with three cars and two vans can use the rate for all five, and a landscaping business with four pickups in use, two of them traded in for newer ones during the year, can use it for all six. OdoTax is built for one driver and their vehicles, with no team plan yet, and its report prices drives at the standard rate, so with five or more in use at once, give your tax preparer the miles, not the report's line 9 total.

Maybe not on that car. The Schedule C instructions allow the standard rate only if you “owned the vehicle and used the standard mileage rate for the first year you placed the vehicle in service,” and Publication 463 says that choice is made “by the due date (including extensions) of your return” for that first year. If 2026 is the first year the vehicle works for the business, choose the rate on your 2026 return; if it has worked for the business since an earlier year you never claimed, ask a tax preparer which method it can use before you file. Actual expenses are open to it and need the same mileage log, and the next car you put to work gets its own first year.

For each business drive, Publication 463's Table 5-1 asks for four things: the date, where you went, the business purpose and the miles. For a business owner the purpose says what the run was for, such as “Supplies — Eastside Wholesale” or “Delivery to Reyes Bakery”; “business” on its own is too thin. Once a year, for each car, it also asks for the total miles, the date it went into business use and what it cost. It has to be written at or near the time, while you still remember the drive; a log kept weekly counts, and paper, a spreadsheet and an app all qualify. OdoTax records the date, both addresses and the miles as you drive, and the purpose is yours to add (what the IRS wants).

A business drive you can't prove isn't allowed, and no part of it can be allowed on a guess: “You can't deduct amounts that you approximate or estimate.” A penalty can come on top: 20% of the tax underpaid through negligence, and the tax regulations count failing to keep adequate records as negligence. Keep the log at least 3 years from the date you file (a return filed early counts as filed on the due date), so a 2026 log on a return filed by April 15, 2027 is kept until April 15, 2030, and keep each year's business-mile total until 3 years after you file for the year you sell the car, because standard-rate miles lower its basis. The IRS doesn't approve or certify mileage apps: what counts is what's in the log and when it was written, and OdoTax's PDF is laid out the way Publication 463 describes, with the purposes and the weekly sort yours to add (keep records for years).

Not for the rest of the year: from the day you turn tracking on, every drive is recorded as you go. For January to now you can't estimate, but you can rebuild drives one by one from what you kept at the time: supplier invoices, delivery notes, bank deposit slips, your calendar or your phone's location history; an invoice backs up a drive, but it isn't the log. If Google Maps Timeline was on, OdoTax can import the drives it kept, and you can add others by hand; the report marks both, and on the free plan they count toward each month's 35 like any other drive, so with more than that to rebuild in a month, go Pro first. A rebuilt drive counts only as far as that evidence backs it up, and it weighs less than one logged at the time. Logging October to December doesn't prove the summer either: Publication 463 lets part of the year stand for the whole only when other evidence shows that part is representative, and a busy season isn't typical of a slow one.

To change a return you already filed, you file an amended return, Form 1040-X, generally within 3 years after you filed it or 2 years after you paid the tax, whichever is later, and if the new figures show less tax, the IRS refunds what you overpaid. The proof rules don't change: no estimates, and a drive rebuilt now counts only as far as contracts, invoices, calendars or a location history from that time back it up. The method is a second question: Publication 463 says the standard mileage rate is chosen “by the due date (including extensions) of your return” for the car's first year in your business, so an amended return may not be able to choose it. OdoTax accepts drives added by hand or imported from Google Maps Timeline back to January 1 three years ago and prices each at the IRS rate for its own date; on the free plan they count toward that month's 35 like any other drive, so for a month with more than that, go Pro first, or an import stops at the limit and a drive added past it lands locked and hidden from the list. Ask a tax preparer first whether amending is worth it and which method your car can use for those years (a log rebuilt after the fact).

No. Between drives the phone's motion sensors, and a boundary around where it last stopped, notice when you pull away; OdoTax then switches GPS on, records the route and the miles, and ends the drive once you've been stopped for about five minutes, with OdoTax closed and the phone in your pocket. That works as long as location is set to Always on an iPhone, or Allow all the time on Android, with Precise on; allow Physical activity (Motion & Fitness on an iPhone) too, or a drive can be noticed a mile or two in, and on Android set battery use to Unrestricted; Settings → Tracking configuration shows anything still missing. Moving the car across a parking lot isn't kept: drives shorter than 0.2 mile or a minute are dropped. On an iPhone you can end a drive as you park with Stop drive on the Lock Screen, or by telling Siri “End my drive in odo” (on your home screen the app is called odo) (how detection works).

Little. On most days the car is parked most of the time, and between drives OdoTax doesn't track where you are: the phone waits for the next drive with the motion sensors it already runs and a boundary around where it last stopped, and GPS runs at full accuracy only while a drive is being recorded. What to watch is the phone's own power saving: on an iPhone, Low Power Mode can slow background work, and on Android a battery saver that limits location can make drives go missing or end early; Settings → Tracking configuration warns about both. On Android you'll see a notification the whole time, “Ready to detect a drive” and then the miles so far, because Android requires one from any app that uses location in the background (battery use).

Yes. The route and the miles come from the phone's GPS, which needs no internet; the drive is kept on the phone and uploads by itself once you're back in signal, and until then Home says “N drives tracked offline.” Sorting or editing a drive and adding an odometer reading need a connection, so do those later. Silent mode and Do Not Disturb don't stop it either, because detection doesn't depend on notifications at all; by default OdoTax sends one reminder a week, on Sunday evening, when drives are waiting to be sorted. A site with no street address is still recorded where you parked, and to find the spot by name next time, save it under Settings → Named places → Add place → My location doesn't have an address — pick on map (without a connection).

Each drive waits until you say what it was: on Home, tap Classify and the drives come up one at a time, tap Business or Personal, or press and hold Business to pick a purpose; on the website you can tick a whole day and mark it at once. The purpose is the line the report prints to say why a business drive was made, and a business drive without one shows “Not recorded” in the PDF. OdoTax starts you with purposes such as Customer visit, Meeting, Errand / supplies and Airport / travel, and you add your own, up to 40 characters, under Settings → Custom purposes: “Bank deposit”, “Supplies — Eastside Wholesale”, “Delivery”, “Estimate — Patel”. After you hold Business and pick one, a single tap on Business sorts the next drive with that same purpose, and the PDF prints each end of a drive as a street address, not your name for the place, so name the customer in the purpose. Sorting once a week is enough: a log kept weekly counts as written at or near the time (business or personal).

Until you change it, yes: work hours start as Monday to Friday, 9 to 6, so a drive inside them is suggested as business and one outside as personal, and a Saturday delivery between two customers comes up as personal, while one from or to the shop, saved as Work, is still suggested as business. A suggestion sorts a drive only when you tap Apply, unless you turn on Auto-classify, which sorts drives by the clock without asking, so set your hours before you switch it on. Under Settings → Work hours, tap Saturday or Sunday to give it hours, or Add shift for evening hours, or switch the off-hours suggestion off (on the website, Settings → Classification → Off hours = personal). Saved places and frequent drives are suggested before the clock, so a drive from or to your saved Home is still suggested as personal, and on an irregular week you may prefer to switch work hours off and sort each drive with a tap (sorting by schedule).

It suggests it: under Settings → Named places, save your home with the kind Home and the shop with the kind Work, and drives between them are offered as Commute, kept out of the deduction but counted, because Schedule C asks for the car's commuting miles. Drives from the shop to a supplier or a customer are offered as business. A drive from home straight to a customer or a supplier is suggested as Personal, because one end is home, so mark it Business when the rules for your setup say it counts. If your home office qualifies, leave the shop as an ordinary place, so drives from home to it aren't offered as Commute (the commute).

No: an account is one person's log, and there's no team plan yet. A phone signed in to yours adds every drive it's on, personal ones too, to your log and to your free count. Each driver needs an OdoTax account of their own and sends reports from it. An employee who drives their own car can make the report with your rate per mile, and it prints as a mileage reimbursement claim. For one who drives the business's van there's nothing to pay back: the van's business miles are the business's deduction, theirs included, so give their report to your tax preparer with yours.

Yes. In the app, open Drives and tap +, pick From and To (a saved place or an address), and OdoTax measures the road between them; change the distance if you went another way, then set the time, the vehicle and the purpose, or on the website use Trips → Add a drive. The drive says Added by hand, with an asterisk in the PDF, and that isn't a mark against it: a log kept by hand is still a log. Drives can be added back to January 1 three years ago, and on the free plan a month that already has its 35 free drives takes no more added by hand. If drives keep going missing, check Settings → Tracking configuration first (a missed drive).

OdoTax runs on an iPhone with iOS 17 or newer and on Android 7 or newer, and the same account opens in any browser at my.odo.tax, where a month of drives fits on one screen. It isn't listed in the App Store and Google Play yet, so Get the app on this page (odo.tax/get) leads to the test version: TestFlight, Apple's app for testing new apps, on an iPhone, and the Android test on Android. If you carry a personal phone and a work phone, sign in to one account on both: each records the drives it's on, and when both record the same drive, OdoTax keeps one. The app, the website and the reports are in English, built for US tax returns (the web account).

The free plan covers 35 drives each calendar month; it needs only an email (no card), doesn't expire, and includes everything else, PDF and CSV reports too. Every drive counts toward the limit, personal ones too, and a long stop starts a new drive: a bank run and back is two drives, a 20-minute stop at a supplier splits a trip in two, and the commute to the shop is two drives a workday on its own, 40 or more a month on a five-day week before a single business drive. Drives past the limit are still recorded but arrive Locked, left out of totals and reports, and the count starts again on the 1st; Settings shows how many free drives are left this month. Pro removes the limit for $7.99 a month or $74.99 a year (the free limit).

Yes: a monthly plan can be canceled any time, Pro runs to the end of the period you paid for, the account then goes back to the free plan, nothing is deleted, and drives recorded while you were paying stay open for good. Drives locked in a month on the free plan stay locked when you subscribe later, though, and once they're out of reach they're hidden from the list, not deleted: only an account's first payment for Pro also reopens the 31 days before it, and only once, so start Pro before a busy month passes 35 drives, not after. Nine months of Pro cost $71.91 month by month; from ten months on, the $74.99 year is cheaper. A plan is managed where you bought it: the App Store, Google Play or the website (change or cancel).

A report, as a PDF and a CSV: in Reports, pick a period (last tax year, a quarter, the year so far, or your own dates), all drives or business only, and a car if you have more than one. Before you make it, sort every drive still waiting, because an unsorted one adds nothing, fill in any purpose the report would print as “Not recorded,” add your odometer readings, and set the car's In business use since date under Vehicles on the website. The PDF's first page has the figures for Schedule C, line 9 and Part IV, and OdoTax doesn't connect to tax software, so you or your preparer type them in, whatever you file with; the CSV opens in any spreadsheet. To hand it over, save your accountant once as a contact and tap Email this report; they don't need an account (send a report).

No. OdoTax keeps the log and applies the IRS standard mileage rate to the drives you mark as business; which drives are business for your work, whether your home office qualifies, and whether the standard rate or actual costs suit your car are for you and your tax preparer. The rules on this page come from IRS Publications 463, 587 and 334 and the Schedule C instructions, and our guides quote them, starting with home office and mileage.

“All the time” (Always on an iPhone) is what lets OdoTax catch a drive that starts while OdoTax is closed; with “only while using,” it records nothing unless OdoTax is open on screen, and during a drive it usually isn't. It also needs Precise location, because a log built from rough positions isn't accurate enough to claim. GPS runs at full accuracy only while a drive is being recorded: once you've parked, the drive ends there and the phone waits for the next one; between drives it is asked where it is when you use Locate in your web account to find a lost phone, an answer kept for 30 days, or when OdoTax support looks into drives that went missing. For hours you don't want logged, Settings → Pause auto-tracking in the app stops detection For 1 hour, For 4 hours, Until tomorrow 9am or For the rest of today, on every phone on your account; nothing is recorded meanwhile, business drives included, but you can add one by hand (what data is kept).

Your customers see a drive only in a report you send them. For each drive OdoTax keeps the route, both addresses, the miles and the times, plus what you add. A map service fits the GPS points to the roads and an address service turns the two ends into street addresses, and under the privacy policy service providers like these get only the data their job needs. Whoever you send a report to sees the addresses of both ends of each drive in it and your purposes, customer names included, and in the CSV your notes and your names for saved places too, but not the route; make a report for business drives only and your personal stops stay out. If you connect OdoTax to Claude, it is sent your drives, totals and saved places when it asks, never a drive's GPS track, and if you report a problem with a drive, a person on the OdoTax team looks at it (what data is kept).
