1. The First Year Is Different
Your first year of self-employment taxes is less about the return itself and more about the habits you set up before it. Every client who arrives in February with a shoebox (or, these days, a phone full of screenshots) pays for the year of skipped setup. This checklist is what we wish every first-year driver, notary, creator, and freelancer did in their first month.
2. 1. Open a Separate Bank Account
The single highest-leverage move. Run all business income through its own account, pay business costs from it, and transfer your profit to personal on a schedule. At tax time, your bank statement becomes your income ledger — no forensics, no missed income, no accidentally-deducted groceries. It also makes the "this was business" position defensible if the IRS ever asks.
3. 2. Start the Mileage Log on Day One
If your work involves driving, the log is your largest deduction and your largest audit exposure. The rules require a **contemporaneous** record — date, miles, business purpose, written at or near the time of the trip. A notes app works; a dedicated app that logs GPS miles works; a reconstruction from memory in March does not. Note that 2026 has two mileage rates (72.5 cents January-June, 76 cents July-December), so your log's dates matter twice as much this year. Our free mileage and toll log gives you the columns the IRS wants to see.
4. 3. Learn Your Forms Calendar
You will receive (or not receive — see #4) 1099 forms in January, and you may need to make estimated payments roughly April 15, June 15, September 15, and January 15. Put all four dates in your phone now, with a reminder two weeks ahead of each. First-year penalty bills are usually small, but they are entirely avoidable, and the habit matters more than the dollars in year one.
5. 4. Understand That Forms Follow Thresholds, Not Taxability
Clients and platforms issue 1099s only above reporting thresholds. You may earn real money and receive zero forms — the income is taxable anyway. Your records are the return's source of truth; the forms are just third-party copies of part of it.
6. 5. Decide Your Set-Aside Percentage
A workable default for many side businesses: move 25-30% of every deposit to a separate tax bucket until you know your real effective rate. Drivers can skip the guesswork with the Driver Tax Estimator; others can bring a couple of months of numbers to a consultation and we will project it properly.
7. 6. Keep Receipts by Category, Not by Shoebox
Categories that matter for most of our clients: platform and service fees, phone and internet (business share), supplies and equipment, professional costs (commissions, insurance, training), and vehicle costs. A photo of each receipt into one folder per month is plenty — the goal is that any number on your return can be traced to a document in under a minute.
8. 7. Know What You Do Not Need Yet
You do not need an LLC to file a Schedule C, you do not need an EIN as a sole proprietor (your SSN works), and you do not need accounting software — a spreadsheet plus the bank account from #1 covers year one for most people. Entity questions become worth answering once profit is consistent; ask before acting, not after.
9. 8. Book One Check-In Before January
Bring your first quarter of records to a preparer before your first filing season rather than after it. A thirty-minute review in the fall — is the log adequate, is the set-aside close, is anything missing — is the cheapest tax advice you will ever get, and it turns your first return from an event into a formality.
