The 2026 tax year is the first full year under the One Big Beautiful Bill Act. The rates are unchanged from 2025, but nearly every threshold moved, several deductions were rewritten, and the estate exclusion jumped to a permanent $15 million. This guide is the complete map: every bracket, deduction, and rate that matters for a 2026 return, with links to the calculators that turn these numbers into your personal estimate. Read it top to bottom once, then use the linked tools for the parts that touch your own return. (Internal Revenue Service)

The 2026 federal income tax brackets
Taxable income — gross income minus deductions — is taxed at seven marginal rates. Only the income inside each slice is taxed at that rate, which is why your effective rate is almost always lower than your top bracket. (Internal Revenue Service)
| Rate | Single (taxable income) | Married joint (taxable income) |
|---|---|---|
| 10% | $0 – $12,400 | $0 – $24,800 |
| 12% | $12,400 – $50,400 | $24,800 – $100,800 |
| 22% | $50,400 – $105,700 | $100,800 – $211,400 |
| 24% | $105,700 – $201,775 | $211,400 – $403,550 |
| 32% | $201,775 – $256,225 | $403,550 – $512,450 |
| 35% | $256,225 – $640,600 | $512,450 – $768,700 |
| 37% | over $640,600 | over $768,700 |
Heads of household and married-filing-separately tables sit between these two. The 2026 federal tax reference lists every filing status. (Internal Revenue Service)
The 2026 standard deduction
Most taxpayers claim the standard deduction. The 2026 amounts are $16,100 for single and married-separate filers, $32,200 for married joint and qualifying surviving spouses, and $24,150 for heads of household — each up slightly from 2025 under IRS Rev. Proc. 2025-32. Itemize only if your mortgage interest, SALT, and charitable gifts exceed these amounts; the standard vs itemized tool settles it in seconds. (Internal Revenue Service)
Long-term capital gains and qualified dividends in 2026
Gains on assets held over one year get preferential rates of 0%, 15%, or 20%, stacked on top of your ordinary income. The 3.8% Net Investment Income Tax adds a surcharge above $200,000 MAGI (single) or $250,000 (joint), creating a top 23.8% rate. The capital gains calculator shows your exact blended rate including NIIT. (Internal Revenue Service)
Self-employment tax and the QBI deduction
Freelancers and sole proprietors pay 15.3% self-employment tax on 92.35% of net earnings — 12.4% Social Security plus 2.9% Medicare — on top of income tax. The Section 199A QBI deduction offsets 20% of qualified business income, made permanent by OBBBA, with a phase-in for service businesses starting at $201,750 of taxable income (single) in 2026. Model both layers with the self-employment & QBI calculator. (Internal Revenue Service)
FICA: Social Security and Medicare in 2026
Employees pay 6.2% Social Security tax up to the $184,500 wage base and 1.45% Medicare on all wages. Above $200,000 (single) or $250,000 (joint), an additional 0.9% Medicare surtax applies. These payroll taxes are identical in every state — they do not depend on where you live. (Internal Revenue Service)
The estate and gift exclusion: $15 million era
The One Big Beautiful Bill Act permanently raised the basic exclusion amount to $15,000,000 per person for decedents dying in 2026 and later ($30,000,000 for couples with portability). The annual gift exclusion is $19,000 per recipient. Gifts above the annual exclusion reduce the lifetime shield. See the estate tax calculator and the gift tax calculator to model your plan. (Internal Revenue Service)
SALT, AMT, and other 2026 limits
- SALT deduction cap: $40,400 for married joint filers ($20,200 separate) in 2026, phasing down above $505,000 joint AGI and reverting after 2030.
- AMT exemption: $90,100 (single) and $140,200 (joint), phasing out above $500,000 / $1,000,000.
- Social Security wage base: $184,500 for 2026.
- Senior deduction: up to $6,000 (single) / $12,000 (joint) for taxpayers 65+, phasing out above $75,000 / $150,000 MAGI, available 2025–2028.

How the three layers stack
The federal return is the largest layer, built from taxable income, the standard or itemized deduction, the marginal brackets, and the credits. FICA is the fixed layer, Social Security up to its wage cap and Medicare across all wages, which does not vary with your bracket. The state layer is the most variable, ranging from zero in nine states to over 13% in California for high earners. For a household that can choose where to live, the state layer is often the biggest single lever, because it is the one that varies the most between two similar-income households. (Internal Revenue Service)
The order in which to plan
Start with the federal structure, because the standard deduction and the brackets set the baseline. Then add FICA, which is fixed and does not respond to planning. Then layer in the state, which is the one you can change by moving. The last lever is the one that is hardest to reverse, which is why a household that is considering a move should model the federal and FICA numbers first, confirm the state layer is actually favorable at their income, and only then commit. A move that looks favorable on a state rate can be neutral once the cost of living and the state property tax are folded in. (Internal Revenue Service)
What this guide covers and what it does not
This guide is a map of the structure, not a calculation for your situation. The specific numbers depend on your filing status, your income level, your state, and the timing of your income and deductions. The tools on this site run the full stack for a given set of inputs, which is where the real answer lives. The map here tells you which levers matter and in what order, so when you run the numbers you know what to look for and which assumption to test first. (Tax Foundation)
