Self-Employment Tax Calculator 2023 and 2022: Figures

Quick Answer: For 2022 and 2023, self-employment tax is 15.3% (12.4% Social Security plus 2.9% Medicare) of 92.35% of net profit, owed once that figure reaches $400. Only the Social Security wage base differs: $147,000 for 2022 and $160,200 for 2023. On $60,000 of profit and no wages, the tax is $8,477.73 in either year.

A self-employment tax calculator for 2022 or 2023 is the same arithmetic as today's, fed with that year's figures from that year's Schedule SE. If you are filing a late return or amending one for either year, use the prior-year form, not the current one, and read the wage base off line 7. This guide gives both years' numbers, worked examples and the deadlines that still apply.

Every figure below comes from the IRS prior-year Schedule SE forms and instructions for 2022 and 2023, and from IRS penalty and refund pages, all read on October 28, 2026.

Which Schedule SE figures changed between 2022 and 2023?

Most of the form stayed the same; the wage base and the optional-method ceiling moved. The table puts the two years side by side, with the line of Schedule SE where each number appears.

The 0.9% Additional Medicare Tax thresholds were also unchanged in both years' instructions: $200,000 for single, head of household and qualifying surviving spouse, $250,000 for married filing jointly and $125,000 for married filing separately. That tax is figured on Form 8959, not on Schedule SE itself.

Get the forms from the IRS prior-year forms and instructions page by searching "Schedule SE" and picking the revision year. The files are named with the year, for example f1040sse--2022.pdf for the form and i1040sse--2023.pdf for the instructions.

How do you calculate self-employment tax for 2022?

Take net profit from your 2022 Schedule C (line 31) and walk Schedule SE line by line. For $60,000 of profit and no W-2 job:

1. Line 4a: $60,000 × 0.9235 = $55,410. This is above $400, so you owe the tax.
2. Line 7: $147,000, printed on the 2022 form.
3. Line 9: $147,000 minus W-2 Social Security wages of $0 leaves $147,000 of room.
4. Line 10: the smaller of $55,410 or $147,000, times 12.4% = $6,870.84.
5. Line 11: $55,410 × 2.9% = $1,606.89.
6. Line 12, self-employment tax: $8,477.73. It goes on Schedule 2.
7. Line 13, deduction for half: $4,238.87, which goes on Schedule 1 and lowers your adjusted gross income.

How do you calculate self-employment tax for 2023?

The steps are identical; only the line 7 figure changes to $160,200. At $60,000 of profit and no wages, the result is the same $8,477.73, because the cap never comes into play.

The year matters when you also had a paycheck. Say you earned $150,000 of W-2 wages and $40,000 of freelance profit:

The same income costs $1,264.80 more in 2023, because the higher wage base leaves room above the salary. Wages plus self-employment earnings come to $186,940, under the $200,000 single threshold, so no Additional Medicare Tax applies in either year.

If you copy a current-year calculator for an old return, this is the line that goes wrong: today's wage base is far higher than either year's, and using it would overstate the 2022 or 2023 Social Security part for anyone with wages near the cap.

Income tax on the same profit, by year

Self-employment tax is only half the bill. The deduction for half of it, the standard deduction and the qualified business income deduction all come before income tax. For the $60,000 single filer with no other income, using each year's standard deduction and Schedule X rates from that year's Form 1040-ES:

The QBI deduction here is the smaller of 20% of qualified business income or 20% of taxable income before the deduction, as the IRS describes it on its QBI deduction page. The 2022 bracket boundaries ($10,275, $41,775 and so on) and the 2023 ones ($11,000, $44,725 and so on) are different, so don't reuse one year's table for the other. For a full spreadsheet build with formulas, the self-employed tax calculator spreadsheet works for any year once you swap in that year's wage base, deduction and brackets.

What does filing a 2022 or 2023 return late cost?

If you owe tax and never filed, three charges build up from the original due date. The 2022 return was due in April 2023, and the 2023 return in April 2024.

• Failure-to-file penalty. The IRS failure-to-file page sets it at 5% of unpaid tax for each month or part of a month the return is late, up to 25%. For a return more than 60 days late, there is a minimum: $450 for returns due in 2023 and $485 for returns due in 2024, or 100% of the tax owed if that is less.
• Failure-to-pay penalty. 0.5% of the unpaid tax per month, also capped at 25%. In a month where both penalties apply, the failure-to-file charge is reduced by the failure-to-pay amount, so the combined monthly rate is 5%, not 5.5%.
• Interest. The IRS charges interest from the due date until the balance is paid, including on penalties, and the rate can change each quarter.

At two to three years late, the failure-to-file penalty on an unpaid balance has already maxed out, which the IRS says happens after five months, while failure-to-pay and interest keep growing. Filing and paying now stops the clock on the parts that are still running. The IRS says it may reduce penalties for reasonable cause.

When can you still get a refund for 2022 or 2023?

The IRS page on the time you can claim a credit or refund sets the limit as the later of three years from when you filed or two years from when you paid. It also treats estimated payments and withholding as paid on the return's due date, and a refund is limited to tax paid within the lookback period before your claim.

What that means for each year as of late October 2026:

• 2023. Payments are treated as made in April 2024, so a late original return or a Form 1040-X filed before April 2027 can still recover an overpayment. If you overpaid self-employment tax, for example by forgetting the deduction for half on line 13, there is still time.
• 2022. Payments count as made in April 2023, which is more than three years ago. If you filed on time in April 2023, the window to amend for a refund ended in April 2026. If you filed later, count three years from the date you actually filed. Some exceptions extend the time, such as federally declared disasters and combat zone service.

None of this limits the IRS's right to collect tax you owe. If the correction increases your tax, file anyway.

Amending a return that got self-employment tax wrong

Use Form 1040-X with a corrected Schedule SE for the year being fixed. The IRS amended-return page says you can file up to three amended returns for the same year, and that software can file 1040-X electronically. It requires a paper amendment in two cases: the return is for tax year 2021 or earlier, or you filed the original on paper earlier in the current year for a prior tax year. A late 2022 or 2023 return mailed this year falls in the second case, so its amendment goes on paper too. If you owe more and file after the April due date, don't calculate interest or penalties yourself; the IRS adjusts them. A federal change can also change your state return, which you correct separately with your state.

Common SE tax errors worth checking on a 2022 or 2023 return:

• Profit entered on Schedule SE without the 92.35% factor.
• Wages on line 8a missed, so Social Security tax was charged above the cap.
• The deduction for half of SE tax left off Schedule 1.
• A 1099-NEC total used as profit, with expenses never subtracted.

Rebuilding a 2022 or 2023 profit figure

The hardest part of a late return is usually the profit number, not the tax math. Income from 1099 forms is a starting point; your bank and card statements for the full year are the complete record of what came in and what you spent. Online banking often shows only recent months, so getting older statements from your bank may take a request.

Once you have the PDFs, QuickBankConvert can turn each statement into spreadsheet rows with date, description and signed amount, so you can tag business income and expenses and total them by Schedule C line. Sorting statements and 1099s for a freelancer return covers the categorizing step, and how long to keep bank statements for taxes explains why those old files are worth keeping after you file.
