What is the self-employment tax rate?

The statutory rate is 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare. Because it applies to 92.35% of net earnings rather than all of them, the effective rate on the figure you type is about 14.13% until the Social Security wage base is reached.

Why is only 92.35% of my earnings taxed?

An employer deducts its half of FICA as a business expense, so the tax code lets a self-employed person reduce net earnings by an equivalent 7.65% before applying the rate. Schedule SE builds that adjustment in, and this calculator applies it automatically.

Does this include federal income tax?

No. Self-employment tax is separate from and additional to income tax, and this page shows only the self-employment portion. For an estimate that adds federal income tax on the same earnings, use the 1099 Tax Calculator, which subtracts the deductible half before applying the brackets.

What happens above the Social Security wage base?

Adjusted net earnings above the wage base stop adding to the 12.4% line, while the 2.9% Medicare line continues without limit. This tool uses the 2024 base of $168,600, and the Social Security Administration announces a new figure each autumn, so check the current year.

Does it handle the Additional Medicare Tax?

No. The extra 0.9% that applies above $200,000 for single filers and $250,000 for joint filers is not modelled here, so a high earner will see a figure that is too low. The Medicare Tax Calculator covers that surtax separately.

What if I also have a W-2 job?

Wages from an employer already count toward the same annual Social Security wage base, but this calculator only sees the number you enter. If your W-2 wages are substantial the Social Security half shown here will be overstated, and Schedule SE handles the coordination on the return.

Is there a minimum before I owe anything?

Under IRS rules, self-employment tax generally applies once net earnings from self-employment reach $400 for the year. Below that threshold there is normally no self-employment tax, although the income itself may still need to be reported on your return.

Does this apply to taxpayers in Pakistan?

No. This calculator implements US IRS rules and reports in US dollars. TaxEase also provides paid tax and corporate services for Pakistan under FBR and SECP rules, which are an entirely separate system with different rates, filings, and deadlines.

Self-Employment Tax Calculator for US Freelancers 2024

Self-Employment Tax Calculator for US Freelancers 2024The Self-Employment Tax Calculator is a free browser-based tool that estimates the US Social Security and Medicare tax owed on net earnings from freelance, contractor, or sole-proprietor work. Self-employment tax exists because nobody withholds FICA from an invoice: a W-2 employee splits 15.3% with an employer, while a self-employed person owes both halves. The calculator applies the 92.35% net-earnings adjustment, caps the Social Security portion at the wage base, leaves the Medicare portion uncapped, halves the result to show the deductible share, and divides the total into four estimated payments. It runs entirely in your browser and produces an estimate, not tax advice.

What people use it for

A rideshare driver reconciling a quarter

A driver finishes July through September with $9,400 left after platform fees and the standard mileage deduction, and has no idea what to send the IRS. Entering that net figure returns roughly $1,328 of self-employment tax on those earnings, which is the number that belongs in the quarterly payment rather than the gross fares the app reported. It also separates the Social Security half from the Medicare half, which matters once a full year is in view.

An agency owner weighing an S-corp election

A designer clearing $140,000 of net profit as a sole proprietor wants to know what the S-corporation conversation is actually worth before paying anyone to have it. Running the current profit shows the full self-employment tax charged on all of it, which is a concrete baseline to compare against paying a reasonable salary and taking the remainder as a distribution that carries no self-employment tax at all.

A first-year freelancer choosing a savings rate

Someone who left a salaried job in March has no withholding for the first time and no instinct for what to hold back. Running two or three plausible annual net figures shows self-employment tax landing near 14% of net earnings each time, which turns an anxious guess into a fixed transfer into a separate account every time an invoice clears, months before anything is due.

A consultant approaching the wage base

A contractor expecting around $200,000 of net earnings sees the Social Security line stop growing while the Medicare line keeps climbing without limit. That makes the wage base concrete rather than theoretical: income above the cap is still taxed, just at 2.9% instead of 15.3%, which materially changes what a fourth-quarter project costs in tax and whether it is worth taking on.

How it works

Enter net self-employment income This is gross receipts minus deductible business expenses, the bottom line of Schedule C rather than total revenue. One field drives the whole calculation, so the expense figure sitting behind it matters as much as the income does.
Press Calculate SE Tax The tool multiplies your net earnings by 92.35% before taxing them, mirroring the employer half that an employee never pays tax on. That single step lowers the base every later line is computed from, so it changes each result.
Read the Social Security line Shown at 12.4% and capped at the 2024 wage base of $168,600. Adjusted earnings above that ceiling add nothing further to this line, which is why the figure flattens abruptly for higher earners rather than rising smoothly.
Read the Medicare line Shown at 2.9% with no ceiling anywhere. Every additional dollar of adjusted net earnings adds 2.9 cents here, however large the year turns out to be, which is what keeps the total climbing after Social Security has stopped.
Note the deductible portion and quarterly figure Half the self-employment tax is an above-the-line adjustment on Schedule 1 that lowers taxable income without lowering this tax. The total is then divided by four as a starting point for estimated payments.

Worked examples

Input: Net self-employment income: $50,000

Result: Adjusted earnings $46,175. Social Security $5,725.70, Medicare $1,339.08, self-employment tax $7,064.78, deductible half $3,532.39, quarterly payment $1,766.19. That total is about 14.1% of the $50,000 typed in, which is the practical rate once the 92.35% step has been applied.

Input: Net self-employment income: $120,000

Result: Adjusted earnings $110,820. Social Security $13,741.68, Medicare $3,213.78, self-employment tax $16,955.46, deductible half $8,477.73, quarterly payment $4,238.87. All of it still sits below the wage base, so the whole amount is charged at the full 15.3%.

Input: Net self-employment income: $200,000

Result: Adjusted earnings $184,700, but only $168,600 feeds Social Security. Social Security $20,906.40, Medicare $5,356.30, self-employment tax $26,262.70, quarterly $6,565.68. Against the $120,000 run, earnings rose 67% while the tax rose 55%, because the capped half stopped growing.

Tips

Deduct every legitimate business expense before you type the number. Self-employment tax is charged on net earnings, so each $1,000 of documented expense removes roughly $141 of self-employment tax on top of the income tax it saves.
Move a fixed percentage of every payment received into a separate account rather than reconciling at year end. Running two or three realistic annual figures here shows how stable that percentage actually is.
Remember the deductible half lowers taxable income, not the self-employment tax itself. It reduces what the income tax brackets see, which is why the 1099 calculator returns a smaller income tax than a naive run would.
If a large project lands in one quarter, do not simply send the quarterly figure four times. Recalculate as the year develops so payments track the income that actually arrived rather than a January projection.
