Question 1

How much of my paycheck goes to taxes?

Accepted Answer

For most Americans, 25–35% of gross pay goes to taxes. This includes federal income tax (10–37% depending on your bracket), FICA taxes (7.65% for Social Security and Medicare), and state income tax (0–10% depending on your state). Your effective tax rate — the actual percentage you pay — is lower than your marginal bracket because only income above each threshold is taxed at the higher rate.

Question 2

What is the difference between effective and marginal tax rate?

Accepted Answer

Your marginal tax rate is the rate applied to your last dollar of income — the top bracket you fall into. Your effective tax rate is the average rate across all your income. For example, on an $80,000 salary you are in the 22% marginal bracket, but your effective federal rate is closer to 15% because the first $11,000 is taxed at 10%, the next $33,725 at 12%, and so on.

Question 3

How is FICA tax calculated?

Accepted Answer

FICA (Federal Insurance Contributions Act) tax is 7.65% of your gross wages as an employee: 6.2% for Social Security (on earnings up to $160,200 in 2023) and 1.45% for Medicare (no wage cap). Your employer matches this 7.65%, so the total FICA contribution is 15.3% of your pay.

Question 4

Does filing status affect how much tax I pay?

Accepted Answer

Yes, significantly. Married Filing Jointly filers benefit from wider tax brackets — for example, the 12% bracket extends to $89,450 for MFJ vs $44,725 for Single filers. Head of Household also gets slightly wider brackets than Single. Choosing the correct filing status is one of the most impactful ways to reduce your tax bill.

Question 5

Which states have no income tax?

Accepted Answer

Nine US states have no individual income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Living in one of these states can meaningfully increase your take-home pay — for example, a $100,000 earner in California pays roughly $8,000 in state income tax, while the same earner in Texas pays $0.
