Quick answer
The 2027 Social Security wage base is $192,300, up $7,800 from $184,500 in 2026. For freelancers, it caps how much profit faces the 12.4% Social Security part of self-employment tax. Only those with profit above about $199,783 pay more, and the most anyone's Social Security tax can rise is $967.20.
The Social Security Administration set the 2027 Social Security wage base at $192,300, up $7,800 from $184,500 in 2026. For freelancers and other self-employed people, this cap decides how much of your profit is hit by the 12.4% Social Security part of self-employment tax. Here is who it affects, by how much, and what is still to come for 2027.
The 2027 numbers at a glance
| 2026 | 2027 | |
|---|---|---|
| Social Security wage base | $184,500 | $192,300 |
| Maximum Social Security part of SE tax (12.4%) | $22,878.00 | $23,845.20 |
| Profit at which you reach the cap* | about $199,783 | about $208,230 |
| Medicare part (2.9%) | No cap | No cap |
| Additional Medicare tax (0.9%) | Above $200,000 single / $250,000 joint | Same thresholds (not indexed for inflation) |
* Self-employment tax applies to 92.35% of net profit, so a sole proprietor with no W-2 wages reaches the cap at the wage base divided by 0.9235.
Who pays more in 2027
Only people whose net self-employment earnings exceed the old cap. If your 2027 profit stays below about $199,783, the higher wage base changes nothing for you: every dollar of your earnings was already taxed at 12.4%, and still is.
| Net profit | SE tax at 2026 rules | SE tax at 2027 rules | Difference |
|---|---|---|---|
| $50,000 | $7,065 | $7,065 | $0 |
| $100,000 | $14,130 | $14,130 | $0 |
| $150,000 | $21,194 | $21,194 | $0 |
| $200,000 | $28,234 | $28,259 | +$25 |
| $250,000 | $29,851 | $30,818 | +$967 |
| $300,000 | $31,606 | $32,573 | +$967 |
Single filer with no W-2 wages. Figures include the 0.9% Additional Medicare tax on net earnings above $200,000. The most anyone’s Social Security tax can rise is $967.20: the $7,800 increase times 12.4%.
If you also have a W-2 job
Wages from a job count toward the same $192,300 cap first. If your 2027 salary is $150,000, only the first $42,300 of your net self-employment earnings is subject to the 12.4% Social Security tax; the 2.9% Medicare part applies to all of it. That is why side earners with a high salary often owe far less self-employment tax than a full-time freelancer with the same side income. Enter both in the self-employment tax calculator to see the split.
Which year’s numbers to use when
- The 2026 return you file by April 15, 2027 still uses the 2026 base of $184,500. Our calculators are set to 2026 for that reason.
- 2027 estimated payments, starting with the April 15, 2027 voucher, should use $192,300 if your profit is near or above the cap.
- Still to come: the IRS publishes the 2027 income tax brackets, standard deduction and QBI thresholds each fall. We will add them here and to the calculators as soon as they are official.
The rest of the 2027 Social Security announcement
The same announcement set a 3.6% cost-of-living adjustment for Social Security benefits starting in January 2027. If you are self-employed and already collecting benefits before full retirement age, the earnings-test limits also rise each year; check the SSA’s 2027 fact sheet for the exact amounts that apply to you.
What to do now
- Profit well under $200,000? Nothing changes. Keep setting aside the same share; the tax set-aside calculator gives you one percentage.
- Profit above $200,000? Budget up to $967 more for 2027 and raise your quarterly estimates slightly. This is also the income range where an S corp election is worth a look.
- Mark the 2027 tax deadlines in your calendar.
