  • Standard deduction) married filing jointly $32,200
  • Standard deduction (married filing separately $16,100
  • Standard deduction) head of household $24,150
  • Single brackets 10% / 12% / 22% / 24% / 32% / 35% / 37%
  • Single thresholds $12,400 · $50,400 · $105,700 · $201,775 · $256,225 · $640,600
  • Joint thresholds $24,800 · $100,800 · $211,400 · $403,550 · $512,450 · $768,700

Take-home is gross income less pre-tax contributions and federal income tax only, your real paycheck will be lower. For a fuller picture use the total tax liability estimator.

Reading the result

Two rates, and only one of them is the one people quote

Almost every conversation about "what tax bracket are you in" confuses two different numbers. Getting them straight changes how you plan.

1

Marginal rate, your next dollar

The rate that applies to the next dollar you earn. It matters for decisions: should I take that extra contract, defer income into January, or put another $5,000 into the 401(k)? Every one of those questions is answered at the margin.

2

Effective rate, your whole year

Total tax divided by total income. It is always lower than your marginal rate because your first dollars were taxed at 10% and 12%. This is the honest answer to "what percentage of my income goes to federal tax."

3

Why the bracket bar matters

Seeing your income split across bands makes the point that no raise ever costs you money. Crossing into a higher bracket only taxes the dollars above the line at the higher rate, everything underneath is untouched.

Knowing the number is step one. Lowering it is step two.

This calculator tells you what the current shape of your year produces. Tax planning is the work of changing that shape before December closes it, retirement contributions, timing of income and expenses, entity structure, and the deductions your practice qualifies for but nobody claimed.

Questions, answered

About federal income tax

What is the difference between my effective rate and my marginal rate?
Your marginal rate is the rate applied to your next dollar of income, the bracket you are currently sitting in. Your effective rate is total tax divided by total income, which is always lower because the earlier brackets taxed you at 10% and 12%. A single filer with $100,000 of income has a 22% marginal rate but an effective rate closer to 13%.
Does a raise that pushes me into a higher bracket cost me money?
No, and this is the single most common misunderstanding in tax. Only the dollars above the bracket threshold are taxed at the higher rate. Everything below it stays where it was. Moving into the 24% bracket does not re-tax your earlier income, and a raise always leaves you with more after tax than before.
What counts as a pre-tax contribution?
Traditional 401(k) and 403(b) deferrals, health savings account contributions, deductible traditional IRA contributions, and pre-tax premiums for health, dental and vision coverage. Roth contributions do not count. Those are made with after-tax dollars and give you the benefit later rather than now.
Should I take the standard deduction or itemize?
Whichever is larger. For 2026 the standard deduction is $16,100 single, $32,200 married filing jointly, $16,100 married filing separately and $24,150 head of household. Most filers do better with the standard deduction unless they have significant mortgage interest, state and local taxes, medical expenses or charitable giving. Note that business expenses are deducted on Schedule C, not here, those reduce your profit before this calculation begins.
Does this include Social Security and Medicare tax?
No. This is federal income tax only. FICA on W-2 wages and self-employment tax on business profit are separate, and for many practice owners self-employment tax is the larger bill. Use the self-employment tax calculator or the total tax liability estimator to see both together.
Why is my take-home number higher than my actual paycheck?
Because the take-home figure here subtracts only federal income tax and the pre-tax contributions you entered. Your real paycheck also loses Social Security and Medicare, state and local tax, and any after-tax deductions such as Roth contributions. Treat it as "what is left after the IRS", not "what hits your bank account".
My practice income varies. What should I enter?
Run it twice, once on a conservative projection and once on an optimistic one. The gap between the two tax figures is the range you should be setting aside for. That is exactly the exercise we do on quarterly planning calls, and it is far more useful than a single point estimate.
