Self-employment tax rate for 2026

The self-employment tax rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare. It is charged on 92.35% of your net profit, so below the Social Security limit it takes 14.13% of the profit itself. The Social Security part stops once your wages and net earnings together reach $184,500 in 2026 ($176,100 in 2025); the Medicare part has no limit.

2026 rule Rate or amount Applies to

Regular-method mechanics follow the current final Schedule SE instructions (2025), with the $184,500 wage base confirmed in IRS Publication 15 (2026). The 2026 Schedule SE source linked below remains a draft. Rules rechecked October 4, 2026. This calculator keeps cents until display; whole-dollar tax-form rounding can differ near the $400 threshold.

How the calculator follows Schedule SE

  1. Net profit. Schedule C line 31, Schedule F line 34 and your share of partnership earnings from Schedule K-1 (Form 1065) box 14, code A, added together (line 3). With more than one business, a loss in one reduces the profit of the others.
  2. 92.35%. The law lets you subtract half of the 15.3% rate, 7.65%, before the tax is worked out, so line 4a is 92.35% of a profit. A loss stays as it is.
  3. The $400 test. Under $400 of net earnings you owe no self-employment tax (line 4c). A profit of $433 gives $399.88; $434 gives $400.80 and the tax applies.
  4. Social Security part. 12.4% of your net earnings, but only up to $184,500 minus your W-2 Social Security wages and tips (lines 7 to 10).
  5. Medicare part. 2.9% of all your net earnings (line 11).
  6. Tax and deduction. The two parts add up to your self-employment tax (line 12, carried to Schedule 2 line 4). Half of it is your deduction (line 13, carried to Schedule 1 line 15).
Net profit Net earnings (92.35%) Social Security Medicare SE tax Share of profit
$20,000 $18,470 $2,290 $536 $2,826 14.13%
$50,000 $46,175 $5,726 $1,339 $7,065 14.13%
$100,000 $92,350 $11,451 $2,678 $14,130 14.13%
$150,000 $138,525 $17,177 $4,017 $21,194 14.13%
$200,000 $184,700 $22,878 $5,356 $28,234 14.12%
$300,000 $277,050 $22,878 $8,034 $30,912 10.30%

No W-2 wages, 2026 figures, worked out with the calculator's own functions. Above about $199,783 of profit ($184,500 divided by 92.35%) the Social Security part stays at $22,878 and only the 2.9% keeps growing, so the share of profit falls.

Self-employment tax when you also have a W-2 job

The $184,500 limit covers wages and self-employment earnings together. Wages and tips that had Social Security tax taken out (Form W-2 boxes 3 and 7) use it up first, and only what is left can be taxed at 12.4% (Schedule SE lines 8a to 10). If those wages are $184,500 or more, the Social Security part of your self-employment tax is zero. The 2.9% Medicare part applies to all your net earnings whatever your wages.

With $150,000 of wages and a $100,000 profit, $34,500 of the limit is left: $4,278 of Social Security tax plus $2,678 of Medicare tax, $6,956 in all. Each employer stops withholding Social Security tax at $184,500 of the wages it pays; the FICA tax calculator shows the withholding and any excess you can claim back.

W-2 wages Net profit Limit left (line 9) SE tax
$0 $100,000 $184,500 $14,130
$100,000 $100,000 $84,500 $13,156
$150,000 $100,000 $34,500 $6,956
$184,500 $100,000 $0 $2,678
$250,000 $100,000 $0 $2,678

Additional Medicare Tax on self-employment income

A further 0.9% applies to self-employment income (Schedule SE line 6) above a threshold for your filing status. If you also have wages, the IRS taxes the wages over the threshold first, then lowers the threshold for self-employment income by your Medicare wages (not below zero). A self-employment loss is ignored. On a joint return both spouses' wages and self-employment income count. The thresholds are set in the law and are not adjusted for inflation.

It is figured on Form 8959, not Schedule SE, and it is not part of the deductible half. Employers withhold it only on wages they pay you above $200,000; nothing is withheld on self-employment income, so include it in your estimated payments.

Filing status Threshold
Married filing jointly (both spouses together)$250,000
Married filing separately$125,000
Single, head of household or qualifying surviving spouse$200,000
Form 8959 instructions Filing status Wages SE income IRS: taxed on Calculator
Example 1 (Ann) Single $0 $130,000 $0 $0 ($0 tax)
Example 2 (Bob) Single $0 $220,000 $20,000 $20,000 ($180 tax)
Example 3 (Carl) Single $130,000 $145,000 $75,000 $75,000 ($675 tax)
Example 4 (Don) Married filing separately $200,000 $150,000 $225,000 $225,000 ($2,025 tax)
Kathleen and Liam Married filing jointly $130,000 $140,000 $20,000 $20,000 ($180 tax)

The worked examples in the 2025 Instructions for Form 8959, run through this calculator. For Kathleen and Liam the IRS prints a tax of $180.00. The draft 2026 Form 8959 moves self-employment income to Part IV (lines 13 to 18); the arithmetic and the thresholds are unchanged.

The deduction for half of self-employment tax

You deduct half of your self-employment tax as an adjustment to income on Schedule 1 (Form 1040), line 15. On a $50,000 profit that is $3,532. The IRS calls it the employer-equivalent portion of the tax. It lowers your adjusted gross income and income tax, but not your net earnings or the self-employment tax itself. Employees cannot deduct the Social Security and Medicare tax taken from their pay.

The deduction also matters for retirement plans. For a SEP IRA or a solo 401(k), the IRS worksheet for the self-employed starts from your net profit and subtracts this deduction to get the net earnings your contribution is based on (Publication 560, Deduction Worksheet for Self-Employed, steps 1 to 3).

Paying self-employment tax during 2026

Self-employment tax is paid through estimated tax, together with income tax. Under the general rule in Form 1040-ES you must pay estimated tax for 2026 if you expect to owe at least $1,000 after withholding and refundable credits, and your withholding and credits will be less than the smaller of 90% of your 2026 tax or 100% of the tax on your 2025 return. If your 2025 adjusted gross income was more than $150,000 ($75,000 if married filing separately for 2026), use 110% instead of 100%. If you also have a job, you can instead have more income tax withheld by giving your employer a new Form W-4.

Who pays self-employment tax, and on what

  • Sole proprietors and independent contractors, members of a single-member LLC that is disregarded for tax, members of a qualified joint venture, and partners in a partnership (including members of a multi-member LLC taxed as a partnership).
  • Partners report their net earnings from Schedule K-1 (Form 1065), box 14, code A. Limited partners count only guaranteed payments for services they actually performed for the partnership.
  • If both spouses have self-employment income, each files a separate Schedule SE. On a joint return the Additional Medicare Tax threshold of $250,000 covers both of you.
  • Age does not matter: the tax applies even if you already get Social Security or Medicare benefits.
  • Wages you earn as an employee are not self-employment income; they owe the employee share of FICA instead. Also left out: fees as a notary public, real estate rents reported on Schedule E (unless you receive them in business as a real estate dealer), dividends and interest (unless you are a dealer in stocks or securities), and gains from selling capital assets.

What the calculator leaves out

  • The optional methods in Part II of Schedule SE. In the 2026 draft, the nonfarm method needs net nonfarm profits under $8,186 and under 72.189% of gross nonfarm income, needs $400 of net earnings in 2 of the 3 prior years, can be used no more than five times, and reports at most $7,560 of net earnings; the farm method is open if gross farm income was no more than $11,340 or net farm profits were under $8,186.
  • Church employee income (taxed from $108.28), ministers and members of religious orders, Conservation Reserve Program payments (line 1b), unreported tips (Form 4137) and uncollected tax on wages (Form 8919).
  • Railroad retirement (tier 1) compensation, fiscal tax years and income covered by an international social security agreement.
  • Income tax. The deduction is shown, but not the income tax it saves.

Frequently Asked Questions

How do I calculate self-employment tax?
Multiply your net profit by 92.35%, then take 12.4% of that amount up to $184,500 (less any W-2 wages that had Social Security tax taken out) and 2.9% of all of it. A $50,000 profit gives $46,175 of net earnings, $5,726 of Social Security tax and $1,339 of Medicare tax: $7,065 in all.
What is the self-employment tax rate for 2026?
15.3%: 12.4% for Social Security and 2.9% for Medicare. It is charged on 92.35% of your net profit, so it comes to 14.13% of the profit itself while you are under the $184,500 Social Security limit. Above that only the 2.9% continues. A separate 0.9% Additional Medicare Tax applies to self-employment income above $200,000 ($250,000 on a joint return, $125,000 married filing separately).
How much self-employment tax do I pay on $100,000?
$14,130 on $100,000 of net profit with no other job: $11,451 for Social Security and $2,678 for Medicare, charged on $92,350 of net earnings. Half of it, $7,065, is deductible for income tax.
Do I pay self-employment tax if I made less than $400?
Not if your net earnings, which are 92.35% of your profit, are under $400. A profit of $433 gives $399.88 and no tax; $434 gives $400.80 and tax is due on all of it. Church employees whose church has elected exemption from employer Social Security and Medicare taxes owe SE tax on church employee income of $108.28 or more.
Is self-employment tax deductible?
Half of it is, as an adjustment to income on Schedule 1 (Form 1040), line 15. On a $50,000 profit that is $3,532. The deduction lowers your income tax only; it does not change your net earnings or your self-employment tax. The 0.9% Additional Medicare Tax is not part of it.
Do I pay self-employment tax if I also have a W-2 job?
Yes, on your self-employment profit. Your W-2 wages use up the $184,500 Social Security limit first, and only the rest of it can be taxed at 12.4%. With $150,000 of wages and a $100,000 profit, $34,500 of the limit is left, so you pay $4,278 of Social Security tax and $2,678 of Medicare tax. With $184,500 or more of wages the 12.4% part is zero.
When is self-employment tax due in 2026?
It is not withheld from business income, so you generally pay it through estimated tax together with your income tax: April 15, 2026, June 15, 2026, September 15, 2026, January 15, 2027. You generally must make estimated payments if you expect to owe at least $1,000 after withholding and refundable credits.
Does the Additional Medicare Tax apply to self-employment income?
Yes. It is 0.9% of self-employment income (Schedule SE line 6) above your threshold, reduced by any Medicare wages you have. A single filer with a $300,000 profit has $277,050 of self-employment income and owes $693 on top of $30,912 of self-employment tax.
Do I still owe self-employment tax if I collect Social Security?
Yes. The IRS instructions for Schedule SE say the tax applies no matter how old you are and even if you already get Social Security or Medicare benefits. The Social Security Administration uses the information on Schedule SE to figure your benefits.
Is self-employment tax the same as FICA?
It covers the same two programs. An employee pays 7.65% of wages (6.2% Social Security and 1.45% Medicare) and the employer pays another 7.65%. Self-employed people pay both halves, 15.3%, but on 92.35% of their profit, and they can deduct half of the tax. Employees cannot deduct their share.
