1. Gather your income
- All 1099-NEC forms from clients who paid you
- Any 1099-K from payment platforms and marketplaces
- Income that did not come with a 1099 (cash, Venmo, Zelle, invoices)
- Bank and platform statements to reconcile totals
2. Organize your deductions
- Business expense receipts, sorted by Schedule C category
- Your mileage log (dates, miles, business purpose)
- Home office square footage, plus rent, utilities, and insurance if using the regular method
- Self-employed health insurance premiums and retirement contributions
If your receipts are scattered, this step is where most deductions get lost. NeoReceipt keeps them categorized all year, so this part is already done.
3. Confirm payments already made
- Your four quarterly estimated payments for the year
- Any federal tax withheld from a W-2 job or a spouse
- Last year's return for the safe-harbor figure
4. File the right forms
- Schedule C, income minus expenses to get net profit
- Schedule SE, self-employment tax on net profit
- Form 1040, where it all comes together
- Do not miss the QBI deduction (up to 20% of net business income)
Estimate your total first with the 1099 tax calculator so there are no surprises.
5. Hit the deadlines
The annual return is due April 15. Quarterly estimates for the next year continue on their own schedule. An extension gives you more time to file, not to pay, so pay any balance by April 15. See the 2026 quarterly deadlines.
Walk into tax season with everything ready. NeoReceipt keeps receipts, mileage, and income organized and export-ready.

A few errors cost freelancers real money every year. Watch for these as you work through the checklist:
- Leaving out income that had no 1099. You must report all self-employment income, including cash, Venmo, and Zelle. The IRS receives copies of your 1099s, so under-reporting is easy to catch.
- Skipping the QBI deduction. The qualified business income deduction can knock up to 20 percent off your net business income, and plenty of filers miss it.
- Forgetting the deductible half of self-employment tax. You can deduct one half of the 15.3 percent SE tax as an adjustment to income.
- Over-claiming mixed-use costs. Only the business-use share of a phone, internet, or vehicle is deductible, not the whole bill.
- Missing quarterly payments. If you owed $1,000 or more and did not pay as you earned, expect an underpayment penalty on top of the tax.
- Losing receipts for cash purchases. Cash spending is fully deductible, but only if you kept the receipt, since there is no bank record to fall back on.
Should you file yourself or hire a pro?
If your return is a straightforward Schedule C with income and expenses, consumer tax software handles it well and keeps costs down. Bringing in a CPA or Enrolled Agent starts to pay for itself when your situation gets more complex: your income jumps into a higher bracket, you elected S-corporation status, you worked across multiple states, you bought major equipment you want to depreciate, or you simply want a second set of eyes on a large deduction.
Either way, organized records are what keep the bill and the risk down. A tax preparer charges less when your expenses are already categorized, and software is faster to fill in when your totals are ready. Clean records all year, not a shoebox in April, is the real time-saver.
