Effective Tax Rate Calculator (Self-Employed, 2026)

Effective vs. marginal: the number everyone gets wrong

When someone says "I'm in the 24% tax bracket," they're talking about their marginaltax rate. That's the rate on the last dollar they earned. It is not what they actually pay on their total income. It is never what they actually pay on their total income.

Your effectivetax rate is the real number — total taxes divided by total income. It's always lower than your marginal rate because the first chunks of your income are taxed at the lower brackets. The U.S. has a progressive tax system, which means "getting a raise will never cost you more than you made." Despite what your uncle says at Thanksgiving.

For self-employed people, the effective rate is especially important because you're paying two taxes: federal income tax and self-employment tax. That 15.3% SE tax hits before the brackets even get involved, which is why freelancers often have a higher effective rate than W-2 employees at the same income level.

How we calculate your effective rate

The calculator above does exactly what a tax preparer would do, in this order:

1. Net earnings: your gross income minus business expenses (Schedule C stuff)
2. Self-employment tax: 15.3% on 92.35% of net earnings (Social Security + Medicare)
3. Above-the-line deduction:subtract half of your SE tax from your income — this is automatic, you don't need to itemize
4. Standard deduction: subtract $16,100 (single) or $32,200 (married filing jointly) for 2026
5. Federal income tax: run the remaining taxable income through the brackets
6. Effective rate:(SE tax + income tax) ÷ net earnings × 100

That last number is the one that matters. It's what you're actually paying. Everything else is just the journey.

A worked example

Say you're single, earned $120,000 freelancing, and had $20,000 in business expenses:

1. Net earnings: $120,000 − $20,000 = $100,000
2. SE tax: $100,000 × 92.35% = $92,350 → $92,350 × 15.3% = $14,130
3. AGI: $100,000 − $7,065 (half of SE tax) = $92,935
4. Taxable income: $92,935 − $16,100 (standard deduction) = $76,835
5. Federal income tax on $76,835: roughly $11,616 (running through the 10%, 12%, and 22% brackets)
6. Total tax: $14,130 + $11,616 = $25,746
7. Effective rate: $25,746 ÷ $100,000 = 25.7%

So even though this person is "in the 22% bracket," their real rate is 25.7% because of self-employment tax. The bracket doesn't tell the whole story. It never does.

Why self-employed people pay more than W-2 employees

If you had a W-2 job paying $100,000, your employer would cover half of FICA (7.65%). You'd only pay the other 7.65% out of your paycheck. As a freelancer, you pay the full 15.3%. That extra 7.65% is roughly $7,000 on $100K of earnings — real money that goes straight to the difference between your effective rate and a salaried person's.

This is not a bug. It's just how being your own employer works. The half you can deduct from your income helps, but it doesn't erase the gap entirely. If someone tells you "freelancers pay less in taxes," they are incorrect.

How to lower your effective rate (legally)

• Track every deduction: business expenses reduce your net earnings, which reduces both SE tax and income tax. A $1,000 deduction saves you roughly $300-$400 depending on your bracket.
• Retirement contributions:SEP IRA (up to 25% of net earnings) or Solo 401(k) contributions reduce your taxable income. They don't reduce SE tax, but they can meaningfully lower your income tax bracket.
• S-Corp election:if your net earnings are above $50K-$60K, electing S-Corp status lets you pay SE tax only on a "reasonable salary" portion. The rest comes as distributions that dodge FICA. This can drop your effective rate by 3-5 percentage points.
• Health insurance deduction: self-employed health insurance premiums are deductible above the line, reducing your AGI before income tax kicks in.

Frequently asked questions

What's a "good" effective tax rate for a freelancer?

There's no universal target, but most self-employed people earning $50K-$150K land somewhere between 22% and 30% effective federal rate. If yours is significantly higher, you might be missing deductions. If it's significantly lower, you're either very good at tax planning or something might be off.

Does this include state taxes?

No. This calculator covers federal income tax and self-employment tax only. State income tax is a whole separate layer. Depending on your state, it could add 0% (Texas, Florida, Wyoming) to 13%+ (California) on top. If you want the full picture, add your state's effective rate to the number above and try not to think about it too hard.

Why is my effective rate higher than my friend's who makes the same money at a regular job?

Self-employment tax. Your friend's employer pays half of FICA. You pay both halves. On $100K of net earnings, that's roughly $7,000 more in tax. You can deduct half of it, but you still end up paying more overall. This is the price of being your own boss. Nobody said freedom was free.
