🧾 How Does Income Tax Work in the U.S.?
The U.S. uses a progressive income tax system, meaning the more you earn, the higher the tax rate applied to portions of your income.
Key points:
- Federal income tax is mandatory nationwide
- State and local taxes may also apply, depending on where you live
- Taxes are typically withheld from paychecks throughout the year
- At tax time, you either receive a refund or owe additional taxes
The tax year runs from January 1 to December 31, and tax returns are usually due by April 15 of the following year.
📄 W-2 vs. 1099: What’s the Difference?
Understanding whether you receive a W-2 or a 1099 form is critical, as it affects how much tax you owe and how you file.
W-2 (Employee)
- Issued to employees
- Taxes are withheld automatically
- Employer pays part of Social Security and Medicare taxes
- Simpler tax filing
1099 (Independent Contractor / Self-Employed)
- Issued to freelancers and contractors
- No taxes are withheld
- You are responsible for paying income tax and self-employment tax
- Requires estimated quarterly tax payments
👉 Many tax surprises happen because people underestimate how much tax they owe on 1099 income.
💰 Most Common Tax Deductions and Credits
Tax deductions and credits can significantly reduce your tax bill if used correctly.
Common deductions:
- Standard deduction (used by most taxpayers)
- Mortgage interest
- Student loan interest
- Charitable donations
Common tax credits:
