Check the year on any figure you read, including this one
This number changes every year, and it is the single most-cited figure in freelance tax writing. That combination produces a specific failure: a page written once, never revisited, still ranking.
At the time of writing, the three articles ranking highest for “how much should I set aside for taxes 1099” state the cap as $168,600 or $160,200 — figures from 2024 and 2023 — presented as current. The 2026 figure is $184,500. ssa.gov One of those articles also publishes the 2023 bracket table labelled 2026.
That is not a cheap shot at competitors. It is the reason this page carries a verification date, and the reason every constant on this site does. If you are reading this after February 2027, the figure above is probably stale too, and the SSA table it links to is the thing to trust.
Where you actually reach it
Not at $184,500 of profit. The cap applies to net earnings, which are 92.35% of net profit, irs.gov so you reach it at $199,783 of profit.
| Net profit | Self-employment tax | Federal income tax | Total federal tax |
|---|---|---|---|
| $180,000 | $25,433 | $21,625 | $47,058 |
| $199,784 | $28,229 | $25,155 | $53,384 |
| $220,000 | $28,798 | $28,985 | $57,783 |
| $300,000 | $31,606 | $60,643 | $92,249 |
Watch the self-employment column. It rises to the cap and then almost flattens — the only growth after that is Medicare and, past the filing-status threshold, the additional 0.9%.
The marginal rate cliff
This is the part worth understanding, because nothing else in the US tax system does it.
An eleven-point drop at a single threshold, going the opposite direction to every income tax bracket you will ever cross.
What it does and does not mean
It does not mean your total tax falls. Income tax brackets keep climbing, and at these levels the 32% bracket is arriving. irs.gov Your combined marginal rate still goes up crossing the cap — just by far less than it did below it.
It does mean the marginal cost of extra work drops sharply once you are past it.
If you also have a salary
The cap is shared across everything you earn, not applied per source. W-2 wages consume it first.
Someone whose salary already fills the base pays no Social Security tax on their freelance income at all. Most calculators get this wrong by charging the full 12.4% irs.gov regardless — see W-2 and 1099 in the same year.
The other threshold above it
Past $200,000 of combined earnings for a single filer, an Additional Medicare Tax of 0.9% begins. irs.gov The thresholds are $250,000 for joint filers and $125,000 for married filing separately, and unlike almost everything else in this file they are statutory and not adjusted for inflation — so they catch more people every year without changing.
It is also not deductible, unlike the rest of self-employment tax.
Where this stops applying
The cap applies to earned income. It does nothing for capital gains, dividends or rental income, which are not subject to self-employment tax in the first place.
And this is federal. State treatment of self-employment income varies and no state mirrors this ceiling.
