Welcome back to my channel Tech Gitter Official. In today’s video, we will learn the complete process of filling out IRS form 1040 for 2025. Whether you’re filing for the first time or just need a refresher, this guide will help you stay on track. So, let’s begin.
If you are a US citizen or resident alien and meet the IRS income limits, you must file form 1040. This form reports your income such as wages, dividends, retirement distributions, and more. Filing ensures you remain compliant and allows you to claim deductions or credits that reduce your tax bill.

Step 1: Personal Information
At the top of the form, enter your full legal name, social security number, and current address. If filing jointly, include your spouse’s details as well.

Step 2: Filing Status
Then choose your filing status: Single, married filing jointly or separately, head of household, or qualifying widow. Pick the option that matches your situation.

Step 3: Digital Assets
Next, you’ll see questions about digital assets like crypto or NFTs. If you bought, sold, or exchanged digital assets, check “Yes” and be prepared to file additional schedules. Otherwise, check “No.”

Step 4: Standard Deduction and Dependents
Fill the option which matches your situation of dependency. After that, fill in details about age and blindness. Then comes dependents. If you are claiming more than four dependents, follow the instructions on the form to add extra dependents and include them in the correct section.
Each dependent listed will need their name, social security number, and relationship to you. Additionally, if you’re claiming a dependent, you’ll need to check boxes to see if they qualify for credits like the Child Tax Credit or Other Dependent Credit.
