Frequently Asked Questions

What is the US federal income tax rate for 2026?

The US federal income tax has seven brackets in 2026 ranging from 10% to 37%, depending on your taxable income and filing status. Most middle-income earners have an effective rate well below their marginal bracket.

How do I calculate my take-home pay after taxes?

Your take-home pay is your gross salary minus federal income tax, state income tax, Social Security (6.2%), and Medicare (1.45%) taxes. Use our US Salary Calculator for an exact breakdown for all 50 states.

What is the difference between marginal and effective tax rate?

Your marginal tax rate is the rate applied to your last dollar of income (your bracket). Your effective tax rate is the average rate across all your income — always lower than your marginal rate because the US uses a progressive tax system.

How much of my salary goes to FICA taxes?

FICA taxes total 7.65% of your gross wages: 6.2% for Social Security (on wages up to $176,100) and 1.45% for Medicare (on all wages). Self-employed individuals pay 15.3% as they cover both the employee and employer share.

What is the standard deduction for 2026?

The 2026 standard deduction is $15,000 for single filers, $30,000 for married filing jointly, and $22,500 for head of household.

How much house can I afford on my salary?

A common rule is to keep your monthly housing costs below 28% of your gross monthly income. Use our Home Affordability Calculator to get a precise answer based on your income, debts, down payment, and current mortgage rates.

What is a good 401(k) contribution rate?

Most financial advisors recommend contributing at least enough to get your full employer match (typically 3–6% of salary), then increasing to 15% of gross income including the match over time. The 2026 contribution limit is $23,500.

Do I owe self-employment tax?

If you earn $400 or more in net self-employment income in a year, you owe self-employment tax (15.3% on net earnings). You can deduct half of SE tax from your gross income when calculating your federal income tax.
