What Are the 2026 Federal Tax Brackets and How Do They Work?

Federal tax is progressive: each layer of taxable income is taxed at its own rate. For single filers in 2026, taxable income up to $12,400 is taxed at 10%, the amount from $12,400 to $50,400 at 12%, $50,400 to $105,700 at 22%, $105,700 to $201,775 at 24%, $201,775 to $256,225 at 32%, $256,225 to $640,600 at 35% and above at 37% (Source: IRS Rev. Proc. 2025-32 — irs.gov/pub/irs-drop/rp-25-32.pdf). Married joint brackets are roughly double: 10% to $24,800, 12% to $100,800, 22% to $211,400 and so on. Only the dollars inside each row are taxed at that rate, so moving into a higher bracket never taxes your lower dollars more. The calculator builds the exact layer stack for your filing status.

Single vs Married Filing Jointly: Which Status Saves More on $75,000?

On $75,000 gross with standard deduction, single leaves $58,900 taxable and $7,670 federal (10.2% effective, 22% marginal) while joint leaves $42,800 taxable and $4,720 federal (6.3% effective, 12% marginal), a $2,950 saving for joint on the same income.

The joint benefit comes from both the larger $32,200 standard deduction and wider brackets: joint 12% runs to $100,800 versus $50,400 single, so more of the $75k stays at 10%-12%. At $150,000 single, the same $75,000 extra from $75k to $150k adds $17,900 in tax at 24% marginal, while joint adds only $13,600, a $4,300 marriage benefit.

Standard Deduction vs Itemizing: Should You Itemize in 2026?

The 2026 standard deductions are $16,100 single, $32,200 joint, $16,100 separate and $24,150 head of household per IRS Rev. Proc. 2025-32, and the 0% capital-gains band to $49,450 single sits inside the 12% ordinary band, so itemizing rarely beats the standard. Filing as head of household on $60,000 with $10,000 itemized SALT plus $8,000 mortgage saves $1,200 versus standard at 12%. (Source: IRS — irs.gov/pub/irs-drop/rp-25-32.pdf). You deduct the larger of standard or itemized. Itemized includes SALT capped at $40,400 in 2026 per OBBBA, mortgage interest on up to $750,000 debt, charitable gifts and medical above 7.5% of income. A single filer with $8,000 SALT and $6,000 mortgage interest has $14,000 itemized, less than $16,100 standard, so standard wins. A joint filer with $18,000 SALT and $15,000 mortgage interest has $33,000 itemized, beating $32,200 standard by $800 and saving $176 at 22% marginal. A $7,000 401(k) on $75,000 single drops taxable from $58,900 to $51,900 and saves $1,540 at 22% marginal, while the same $7,000 on $40,000 single saves only $840 at 12% marginal, showing bracket leverage.

How Much Will My Take-Home Pay Actually Be After FICA?

FICA is separate from income tax: Social Security 6.2% on the first $184,500 of wages in 2026 and Medicare 1.45% on all wages, with an extra 0.9% above $200,000 single or $250,000 joint (Source: IRS Publication 15, irs.gov/pub/irs-pdf/p15.pdf). On $75,000 single, FICA is $4,650 + $1,088 = $5,738, so total tax is $7,670 + $5,738 = $13,408 and take-home is $61,592 yearly ($5,133 monthly). On $150,000 single, federal is about $25,570 and FICA is $9,300 + $2,175 = $11,475, total $37,045 and take-home $112,955.

Self-employed pay both halves: 12.4% Social Security up to $184,500 plus 2.9% Medicare, but can deduct half. Model net self-employment with the Crypto Tax Calculator for the different cost-basis rules that also affect taxable income.
