Record-Keeping for Independent Service Providers: Receipts, Mileage and Invoices

Good records don't just make tax season faster — they're what backs up every deduction if the IRS ever asks. For an independent service provider, that mostly comes down to three habits: a separate business bank account, receipts and invoices organized by year, and a mileage log kept close to when you actually drove. Here's what the IRS expects, as of September 2026.

This is general information, not tax advice.

What records should you actually keep?

The IRS's own guidance, in Publication 583, is more relaxed than most people expect: "Except in a few cases, the law does not require any specific kind of records." What it does require is a system that clearly and consistently shows your income and expenses. In practice, that means:

• A separate bank account for the business, so business deposits and expenses aren't tangled up with your personal spending.
• Receipts and invoices, for what customers pay you and what you spend, organized by year and by type of income or expense.
• Deposit slips and canceled checks, or their digital equivalents.
• Any 1099s you receive, even though the income they report should already be in your own records — you owe tax on all your income whether or not a 1099 shows up for it. This is general information, not tax advice.

Electronic records count the same as paper ones. A photo of a receipt, saved and organized by month, satisfies the same rule as a filed paper copy.

How long should you keep them?

Longer than the "3 years" number most people have heard, in some cases. The IRS's baseline is 3 years from when you filed, but several situations stretch that out:

How do you track vehicle expenses?

If you deduct mileage or vehicle costs for driving to jobs, the IRS wants a contemporaneous log — one built as you go, not reconstructed at tax time. Publication 463 states it directly: "You can't deduct amounts that you approximate or estimate." For every trip, record:

• the date,
• where you went,
• the business purpose of the trip, and
• your odometer reading or the mileage.

A log you update weekly counts as timely — you don't need to write it down mid-drive. A phone note, a small notebook kept in the vehicle, or a mileage-tracking app all work, as long as the entries are close to when the trip happened. The current standard mileage rate isn't printed here because it changes annually; check the IRS's mileage rate page before calculating a deduction.

What about invoices to customers?

Beyond what the IRS asks for, a clear invoice trail is worth keeping for your own sake:

• Invoice every job, even a small cash one, so you have a record independent of what a customer or payment platform reports.
• Keep a copy of every invoice you send, with the date, the work, the amount and how it was paid.
• Note the payment method — cash, check, card, an app — since that's often the easiest thing to forget by the time you're doing taxes months later.
• Match invoices to deposits periodically, rather than waiting until year-end to reconcile everything at once.

Organizing by category, not just by date

Sorting receipts by month gets you most of the way there, but grouping them by type of expense makes tax time and any future question about a specific deduction much faster to answer:

• Materials and supplies bought for jobs.
• Tools and equipment, kept separate since some purchases may be handled differently than routine supplies.
• Vehicle expenses, backed by your mileage log.
• Subcontractors or helpers you paid, if any.
• Marketing and business expenses — a website, business cards, a listing on a platform.

A simple folder structure (physical or digital) with one section per category, refreshed monthly, turns "find every receipt from March" into a five-minute task instead of an afternoon.

Keeping records tied to your other paperwork

A few other records worth filing alongside your income and expense records, once you have them:

• Your certificate of insurance, if you carry any coverage — keep the current one somewhere you can find and send it quickly.
• Your local business license paperwork, since it renews annually in most Northern Virginia counties — see getting a business license in Arlington, Fairfax or Prince William for how that works and when it's due.
• Any trade or contractor license documentation, if your work requires one.

Building the habit

None of this needs to be complicated from day one:

1. Open a separate checking account for the business, if you haven't already.
2. Pick one place — a folder, a spreadsheet, an app — for every receipt and invoice, organized by month.
3. Keep a mileage log in your vehicle or on your phone, and fill it in weekly if not daily.
4. Set a recurring reminder to reconcile invoices against deposits, monthly or quarterly rather than once a year.
5. File your 1099s and tax return copies in the same system, and keep them per the table above.
