If you are an Indian living or working in the United States whether on an H-1B, L-1, F-1 (OPT), or as a Green Card holder: Form 1040 is the backbone of your US tax filing.
Every year, this single form tells the IRS:
- How much money you earned
- Where it came from (US, India, or elsewhere)
- How much tax you already paid
- Whether you owe more tax or are due a refund
This guide explains Form 1040 in simple language, with special focus on Indian taxpayers and NRIs in the US.
What Is Form 1040?
It is the official US Individual Income Tax Return.
You use it to report:
- Salary or wages from US jobs
- Freelance or consulting income
- Interest, dividends, or investment income
- Foreign income (including income from India, if applicable)
- Credits, deductions, and taxes already paid
If you are a US tax resident (based on the Substantial Presence Test or Green Card), you will most likely file Form 1040, not Form 1040-NR.
Who Should File Form 1040?
- An Indian citizen working in the US
- An NRI who has become a US tax resident
- A Green Card holder
- A dependent spouse working or earning income
- Someone with both US and Indian income
Important for NRIs: Even income earned in India (rent, interest, capital gains) may need to be reported on this Form if you are a US tax resident.
Form 1040 vs Form 1040-SR: What’s the Difference?
Form 1040
- Standard tax return for most taxpayers
- Used by all age groups
Form 1040-SR
- Optional version for taxpayers aged 65 or older
- Larger font, simpler layout
- Uses the same schedules and rules as Form 1040
If you’re an NRI parent or senior citizen filing US taxes, 1040-SR can be more comfortable, but it does not change tax calculations.
Understanding the Structure of Form 1040
Think of this form as a summary page.
It shows:
- Total income
- Adjustments and deductions
- Tax owed
- Credits
- Payments made
- Refund or balance due
Most detailed information goes into additional schedules.
Form 1040 Schedules Explained (Very Important for NRIs)
Schedule 1 – Additional Income & Adjustments
Used if you have income beyond a regular salary, such as:
- Unemployment compensation
- Gambling or prize winnings
- Interest income not on W-2
- Indian income that is taxable in the US
Also used for adjustments like:
- Student loan interest
- Educator expenses
Many Indians with side income or foreign income need Schedule 1.
Schedule 1-A – Additional Deductions
This schedule applies if you are claiming:
- Qualified overtime or cash tip deductions
- Qualified vehicle loan interest
- Enhanced deduction for seniors
Not everyone needs this, but it’s helpful for working professionals and seniors.
Schedule 2 – Additional Taxes
Used if you owe extra taxes such as:
- Self-employment tax (very common for consultants on 1099)
- Alternative Minimum Tax (AMT)
- Additional taxes on IRAs or retirement accounts
If you’re an Indian consultant or freelancer in the US, Schedule 2 is critical.
Schedule 3 – Additional Credits & Payments
Used to claim credits like:
- Foreign Tax Credit (very important for Indians earning in India)
- Education credits
- Payments made with a filing extension
NRIs with Indian income taxed in India often use Schedule 3 to avoid double taxation.

Online Tools That Make Filing Easier
The IRS provides helpful tools, including:
- Free File – Free e-filing software for eligible taxpayers
- IRS Online Account – View payments, returns, transcripts
- Tax Withholding Estimator – Helps avoid underpayment penalties
These tools are especially useful for first-time Indian filers.
Security, Compliance & Fraud Protection
For NRIs managing taxes across countries, security matters.
The IRS offers:
- Identity Protection PIN (IP PIN) to prevent fraud
- Clear processes to report identity theft or scams
- Secure online access to tax records
Using these tools reduces risk, especially if you file from outside the US or travel frequently.
