Step 1: Confirm Whether You Need to File

You generally must file if any of these apply:

!You are a U.S. citizen or resident alien with income above the IRS filing threshold for your filing status and age.

Step 2: Gather Every Required Document

•1099 forms (contract work, interest, dividends)
•Previous year's tax return
•Social Security numbers for dependents
•Records of deductions and credits

Step 3: Understand Form 1040

Your federal return is filed on Form 1040. It captures:

•Income
•Adjustments
•Taxable income
•Credits and payments
•Final refund or balance owed

👉 What Is Form 1040?

Step 4: Calculate AGI and Taxable Income

AGI (Adjusted Gross Income) is your starting point after specific adjustments.

Taxable Income is what remains after deductions.

Standard vs. Itemized Deduction determines which deduction route lowers your tax more.

Understanding these terms determines how much tax you actually owe.
