Year-End Tax Moves for Freelancers (December Checklist)

Short answer: before December 31, bring your deductions current, make any needed equipment purchases, fund a self-employed retirement plan, and time income and expenses to your advantage. Each lowers your net profit, which cuts both income tax and the 15.3 percent self-employment tax. A few moves (like IRA and SEP-IRA contributions) can wait until the filing deadline.

1. Catch up on every deduction

The cheapest tax move is claiming what you already spent. Make sure every business receipt is captured and categorized, and that your mileage log is complete at 72.5 cents per mile for 2026. Uncategorized receipts and untracked miles are pure lost deductions. This is the fastest win, and it costs nothing.

2. Fund a retirement plan

A SEP-IRA or Solo 401(k) can shelter a large share of net profit from income tax while you save for retirement. The Solo 401(k) generally must be established by December 31, though contributions can follow; SEP-IRA contributions can be made up to the filing deadline. This is often the single biggest lever for a profitable freelancer.

3. Time income and expenses

If you expect a lower-income year next year, consider deferring December invoices to January.
Prepay deductible expenses (software renewals, supplies, subscriptions) before December 31 to claim them this year.
Buy and place needed business equipment in service before year end to deduct it, often in full under Section 179.

Only spend on what your business actually needs. A write-off returns a fraction of the cost, not the whole thing.

4. Square up your Q4 estimate

Check whether your quarterly estimated payments cover your year. The Q4 payment is due January 15, 2027. Paying enough during the year keeps you inside the safe harbor and avoids an underpayment penalty. Run the numbers with the quarterly tax calculator.

Close the year with every deduction captured. NeoReceipt keeps your receipts and mileage organized so year-end is a review, not a scramble.

Frequently asked questions

What is the deadline for year-end tax moves?+

Most must be done by December 31 to count for the current tax year, including equipment purchases, buying supplies, and timing income. A few, like SEP-IRA and traditional IRA contributions, can be made up to the tax filing deadline the following year.

How can I lower my self-employment tax before year end?+

Bring your deductions current (log every receipt and mile), make eligible equipment purchases and place them in service by December 31, and contribute to a self-employed retirement plan. Each reduces net profit, which lowers both income tax and the 15.3% self-employment tax.

Should I buy equipment before December 31?+

If you need it anyway, buying and placing business equipment in service before year end lets you deduct it this year (often in full under Section 179). Do not buy things you do not need just for the write-off; you only save a fraction of the cost in tax.

Can I still contribute to retirement for last year?+

Yes. SEP-IRA and traditional IRA contributions can generally be made up to the filing deadline the following year and still count for the prior tax year, which makes them a powerful last-minute lever.
