Deductions for freelancers
A business deduction is worth more to you than to an employee, and more than your tax bracket suggests, because it reduces self-employment tax and income tax at the same time. irs.gov
What a dollar of deduction actually saves
Thirty cents on the dollar at that level, against a 22% marginal income tax bracket. irs.gov The gap is self-employment tax, which an employee’s deduction never touches.
There is a wrinkle in the other direction: reducing profit also reduces the qualified business income deduction, since that is a fifth of a now-smaller number. irs.gov The figures above are net of that.
“Thirty cents” is the best case, not the rule
That figure holds for a Schedule C expense at a comfortable income. Across the deductions this cluster covers, the actual return runs from about ten cents to about thirty — a threefold spread for the same word.
Two things move it, and neither is your bracket.
Which line of the return it goes on. A Schedule C expense reduces net profit, so it cuts self-employment tax and income tax together. An adjustment on Schedule 1 — health insurance, retirement contributions — is claimed after self-employment tax has already been computed, so it never touches it. irs.gov
How much room is left below you. In a thin year the standard deduction has already taken income tax to zero, so a deduction can only reach self-employment tax — which is why the worst time to accelerate a purchase is the year you can least afford it. And a contribution large enough to walk you down through the brackets is worth less at the top than at the bottom.
What it does not do
A deduction is not a purchase discount.
That sentence is the whole of December tax planning, and it is the one most often reversed in conversation.
The rule, in one sentence
An expense is deductible when it is ordinary — common in your line of work — and necessary — helpful and appropriate for it. Not indispensable. Helpful.
Most disputes are not about whether an expense is ordinary. They are about the share that is business rather than personal, which is where the specific rules below come from.

The mileage rate changed mid-year in 2026
Worth flagging on this page because almost nothing else has caught up: the IRS set two standard mileage rates for 2026. irs.gov
The practical consequence is that mileage has to be logged with dates, not just totals. A year’s driving multiplied by one rate is wrong no matter which of the two you pick. Any calculator or spreadsheet holding a single 2026 figure is wrong for half the year.
Everything in this cluster
- Home office: simplified or actual — where the breakeven between the two methods sits
- Mileage or actual vehicle expenses — and why the first-year choice locks you in
- What is not deductible — the list that saves more trouble than the deductions do
- The health insurance deduction — the big exception to everything above: it never touches self-employment tax
- Retirement contributions as a deduction — the largest one available, and the one whose limit is most often computed wrong
- The meals deduction — half, not all, and the temporary restaurant rule most advice still quotes has expired
- Section 179 vs bonus depreciation — and why most solo operators need neither
Timing, since it is September
Deductions land in the year you incur them. A purchase made on 31 December counts for this year; the same purchase on 2 January does not.
That is a real lever and a small one. It is worth accelerating a purchase you were going to make anyway. It is not worth making a purchase to accelerate.
Where to stop and ask
Anything where the personal share is genuinely arguable — a vehicle used both ways, a room that is sometimes a spare bedroom, a trip that had a holiday attached — is worth a preparer’s time. Those are the areas where an audit actually looks, and where the answer depends on facts rather than on arithmetic.
