Dog walker taxes, bookkeeping and mileage

This is general information for dog walkers, not tax or legal advice. Tax rules change, they depend on your own facts, and they differ by state. Everything below links to the IRS page it came from so you can read the original. Check your own situation with a tax professional before you file anything.

Separate the money before anything else

One business account and, if you can, one card that is only used for the business. This is not about looking professional. It is about what happens in eleven months when you try to remember whether a $64 charge at a pet shop was leashes for work or a bed for your own dog.

The IRS does not require a particular bookkeeping method for a small business. Its recordkeeping guidance says there is no required method, but that you must use one which clearly and accurately reflects your gross income and expenses, and that your records should substantiate both. A separate account is the simplest way anyone has found to do that, because the bank keeps the record for you.

Three things to set up in the same hour:

• A business checking account, in your business name if you have one.
• One card, used only for business, with the statement emailed to you monthly.
• A folder, paper or digital, where receipts go the day they happen.

Track dog walking income by client, not in a lump

A single monthly total tells you what came in. It does not tell you which client is worth keeping, which one has quietly stopped booking, or which service is carrying the business. Record every payment against the client who made it.

That last row matters more than it looks. When a card processor reports what you were paid, it generally reports the gross amount, not what landed in your account after its fee. If your own records only ever hold the net figure, the two will not agree and you will spend a February evening finding out why.

The mileage log

Driving between clients is the biggest recurring cost most dog walkers have, and the one most likely to be recorded badly. The good news is that the IRS is specific about what a record needs to contain.

What a compliant log records

Publication 463 sets out the elements you have to be able to show for a car expense. In plain terms:

Four things the same publication says that are easy to get wrong:

• Write it at or near the time. A timely kept record has more value than a statement written later, when recall is worse. A log you keep weekly still counts as timely kept.
• A computer record counts. Written evidence is preferred over memory alone, and a record prepared on a computer is treated as an adequate record.
• You cannot deduct amounts you approximate or estimate.That sentence is in Publication 463 in those words. "About 40 miles a day" is not a log.
• An established route is easier than it looks. The publication gives a sales-route example where you record the length of the route once, then the date of each trip at or near the time, plus your total miles for the year. A dog walker on a fixed Tuesday round is in almost exactly that position.

That last point is a real argument for a route that repeats. It is also one more reason to read dog walking schedule and route planning.

The standard mileage rate, and why the date matters this year

The IRS publishes a standard mileage rate for business use. For 2026 it is split across the year, which is unusual and easy to miss. Read off the IRS rate table on 2 September 2026:

So the arithmetic depends on when the miles happened. Say you logged 620 business miles in June and 700 in August. That is 620 at 72.5 cents, which is $449.50, plus 700 at 76 cents, which is $532.00. Together, $981.50 for those two months.

Rates change, sometimes in the middle of a year. Always check the current IRS standard mileage rate for the dates you actually drove.

You pick one method, not both

The IRS gives two ways to work out car costs, and Topic no. 510 describes them. The standard mileage rate is one. Actual expenses is the other, and that is where gas, oil, repairs, tires, insurance, registration and licences live, split between business and personal use.

Three rules from that page that catch people out:

• To use the standard mileage rate for a car you own, you have to choose it in the first year the car is available for use in your business. After that you can switch between methods in later years.
• For a leased car, choosing the standard mileage rate means using it for the whole lease period, including renewals.
• Parking fees and tolls for business use are deductible separately, under either method.

Which method leaves you better off depends on your vehicle, your mileage and your year. It is a good question for a tax professional and a bad one to guess at.

Quarterly estimated taxes exist

Nobody withholds tax from a dog walking payment. The IRS says individuals, including sole proprietors, generally have to make estimated tax payments if they expect to owe $1,000 or more when their return is filed, and that you can face a penalty for paying late even if you end up due a refund.

Estimated tax is not only income tax. It also covers self-employment tax, which the IRS describes as Social Security and Medicare taxes for people who work for themselves. The self-employment tax rate is 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare.

What that means for you personally depends on your other income, your deductions and your filing situation. Take the numbers to a tax professional and let them tell you what to pay and when. That is a couple of hundred dollars that pays for itself the first time it stops a penalty.

The 1099-K from Rover, Wag and your card processor

If you walk dogs through a platform, or take cards, some of your income is being reported to the IRS whether or not you report it the same way.

From the IRS page on Form 1099-K, checked in September 2026:

• It is a report of payments you received for goods or services through payment cards, or through payment apps and online marketplaces.
• The company files it with the IRS and must send you a copy by January 31.
• If clients pay you directly by credit, debit or gift card, your processor sends one no matter how many payments you took or how large they were.
• A payment app or online marketplace is required to send one when payments for goods or services total over $20,000 in more than 200 transactions, and the IRS notes they may send one at lower amounts anyway.
• You use it with your other records to figure your taxable income, not instead of them.

The practical consequence: a walker with clients on Rover, clients paying by card and clients paying cash may receive one form, or two, that between them cover only part of the year. Your own record of every payment is what makes the picture whole.

Keep the receipts

Publication 463 says you generally need documentary evidence, such as receipts, cancelled checks or bills, to support your expenses. For a dog walking business that usually means:

• Insurance premiums and any renewal documents.
• Software subscriptions, including this one.
• Leashes, harnesses, poop bags, treats, towels, a first aid kit.
• Phone bills, if the phone is used for the business.
• Business licence or registration fees.
• Marketing: flyers, business cards, a domain, printing.
• Parking and tolls, which stay separate from mileage.

Photograph a paper receipt the day you get it. Thermal paper fades, and a blank strip proves nothing.

If you have not costed the business out yet, what it costs to start a dog walking business lists most of the categories above before you have to file them.

A monthly routine that takes twenty minutes

1. Open the business account and check every payment landed against a client.
2. Photograph and file any receipt still in a pocket or a glovebox.
3. Total the month by client and by service.
4. Total your business miles for the month from the log.
5. Move money to the account you keep for tax, at whatever level your professional set.

Do it on the same day each month, in the fixed admin hour you set aside for everything else. Twenty minutes twelve times is a very different experience from a lost weekend in April.
