Tax Cut-Off Point: Brackets, Deductions, and Surtaxes

Federal tax law is built on a stack of income cut-off points, and the first one that matters for 2026 is the standard deduction: $16,100 for single filers and $32,200 for married couples filing jointly. Income below that line owes zero federal income tax.¹ Above it, your income moves through seven brackets, then hits a series of separate thresholds for capital gains, payroll taxes, surtaxes, and phase-outs on credits and deductions. Every federal tax cut-off point that applies to individual filers in 2026 is laid out below.

The Income Level That Requires You to File

Federal law requires a tax return from anyone whose gross income meets or exceeds a threshold tied to filing status and age.² For 2026 those thresholds match the standard deduction, because the personal exemption is currently set to zero. A single filer under 65 doesn’t need to file until gross income reaches $16,100. A married couple filing jointly doesn’t need to file until combined income reaches $32,200.¹

Filers who are 65 or older get a higher threshold because the tax code grants an additional standard deduction for age. The same additional deduction applies to blind taxpayers. The bump depends on filing status and can add roughly $1,600 to $2,000 to the income you can earn before a return is required.

Self-employment breaks this pattern. If your net self-employment earnings reach just $400, you must file a return regardless of your total gross income.³ Freelancers and gig workers who also hold a W-2 job often miss this one.

The Standard Deduction Zero-Tax Zone

Once you’re over the filing threshold, the standard deduction still shields a slice of income from tax. It subtracts a flat amount from your gross income before any rates apply.⁴ For 2026:

Single or married filing separately: $16,100
Married filing jointly: $32,200
Head of household: $24,150

These figures reflect both routine inflation indexing and recent legislation.¹ A single filer earning exactly $16,100 owes no federal income tax. Earn $16,101, and only that one dollar enters the taxable-income calculation. The head-of-household figure sits deliberately higher than the single amount because that status is reserved for unmarried taxpayers maintaining a home for a qualifying dependent.

The Seven Federal Tax Brackets for 2026

Income above the standard deduction flows through seven brackets at progressively higher rates. The system is marginal. Moving into a higher bracket never raises the rate on the income already taxed in lower brackets; only the dollars sitting inside the new bracket get the new rate.⁵

For a single filer in 2026:¹

10% on taxable income up to $12,400
12% from $12,401 to $50,400
22% from $50,401 to $105,700
24% from $105,701 to $201,775
32% from $201,776 to $256,225
35% from $256,226 to $640,600
37% above $640,600

For married couples filing jointly, each bracket runs roughly double the single-filer width. The 10% bracket covers taxable income up to $24,800, the 12% bracket goes to $100,800, and the top 37% rate begins above $768,700.¹

A worked example makes the marginal math concrete. A single filer with $60,000 in taxable income doesn’t pay 22% across the board. They pay 10% on the first $12,400 ($1,240), then 12% on the next $38,000 ($4,560), then 22% on only the remaining $9,600 ($2,112). Total federal income tax: $7,912, an effective rate of about 13.2%. A raise into a new bracket never cuts your take-home pay.

Long-Term Capital Gains Cut-Off Points

Profits from investments held longer than a year are taxed on a separate ladder. For single filers in 2026:

0% on taxable income up to $49,450
15% from $49,451 to $545,500
20% above $545,500

For married couples filing jointly, the 0% rate runs up to $98,900, the 15% rate covers $98,901 to $613,700, and the 20% rate applies above that. The 0% band is especially useful for retirees and lower-income investors: if total taxable income (including the gain itself) stays below the cut-off, appreciated shares can be sold with no federal capital gains tax.

Short-term gains, from assets held a year or less, don’t get these rates. They’re taxed as ordinary income through the seven brackets above.

Where Social Security Tax Stops

Payroll taxes have their own cut-offs, entirely separate from income tax. The Social Security portion (OASDI) is 6.2% on wages, matched by another 6.2% from your employer.⁶ For 2026, the maximum earnings subject to Social Security tax is $184,500.⁷ Once year-to-date wages hit that ceiling, withholding stops for both sides.

The Medicare portion has no wage cap. You pay 1.45% on every dollar of wages, no matter how high your income climbs.⁸

The $200,000 and $250,000 Surtax Triggers

Two separate surtaxes kick in at similar income points, and both are frozen in the statute with no inflation adjustment.

Additional Medicare Tax

Wages above $200,000 for single filers, or $250,000 for married couples filing jointly, carry an extra 0.9% Medicare tax on every dollar over that line.⁶ Employers don’t match this one. They begin withholding it once wages from that job cross $200,000, regardless of filing status. A married-filing-jointly household with combined wages under $250,000 can recover any over-withholding on the return.⁹

Net Investment Income Tax

A 3.8% surtax applies to investment income (interest, dividends, capital gains, rental income, and similar passive earnings) once modified adjusted gross income exceeds $200,000 single or $250,000 joint.¹⁰ The tax hits the lesser of net investment income or the amount MAGI exceeds the threshold. Because these thresholds don’t index for inflation, more taxpayers cross them each year.

Income Cut-Offs for Credits and Retirement Accounts

Many tax breaks shrink gradually across a phase-out range rather than disappearing at a single point. These phase-outs create hidden marginal rate bumps.

Child Tax Credit

Phase-out starts at $200,000 AGI for single filers and $400,000 for married couples filing jointly. The credit drops by $50 for every $1,000 above the threshold.¹¹

Earned Income Tax Credit

The EITC runs the opposite direction from most benefits, targeting lower-income workers. For 2026, the maximum credit for a taxpayer with three or more qualifying children is $8,231.¹ The credit phases in with earnings, plateaus, then phases out entirely once AGI exceeds the limit for family size and filing status. A single filer with no children loses eligibility at a far lower income than a married couple with three kids.

Traditional IRA Deduction

If you or your spouse is covered by a workplace retirement plan, the traditional IRA deduction phases out inside set MAGI ranges. For 2026, single filers covered by a workplace plan get the full deduction up to $81,000 MAGI and a partial deduction up to $91,000. Married couples filing jointly phase out between $129,000 and $149,000.

Roth IRA Contributions

Roth eligibility phases out between $153,000 and $168,000 MAGI for single filers and between $242,000 and $252,000 for joint filers.¹² Above the upper number, direct Roth contributions are off the table.

Student Loan Interest Deduction

You can deduct up to $2,500 in student loan interest. The deduction starts shrinking at $85,000 MAGI for single filers and disappears at $100,000. For joint filers, the range runs $175,000 to $205,000.

Alternative Minimum Tax Exemption

The AMT is a parallel calculation that limits certain deductions and credits. You compute liability under both the regular system and the AMT rules and pay the higher figure. For 2026 the AMT exemption is $90,100 for single filers and $140,200 for married couples filing jointly. The exemption begins phasing out once AMT income exceeds $500,000 single or $1,000,000 joint, decreasing by 50 cents per dollar above the threshold.¹ The AMT most often catches taxpayers who exercise incentive stock options, claim large state and local tax deductions, or have substantial miscellaneous itemized deductions.

Why the Numbers Change Every Year

Nearly every dollar figure above will change for 2027. The IRS adjusts most thresholds annually using the Chained Consumer Price Index, which prevents “bracket creep” where inflation pushes filers into higher brackets without any real gain in purchasing power. Two thresholds are the exception: the $200,000 and $250,000 triggers for the Additional Medicare Tax and the Net Investment Income Tax are written directly into the statute with no inflation adjustment.¹⁰ They’ve been frozen since 2013, and each year more taxpayers cross them as wages rise. The IRS typically releases the following year’s inflation-adjusted figures in the fall.
