Preparing a marriage-based green card application often feels like you are drowning in a sea of paperwork. Just when you think you are done proving your relationship is real, you hit the financial hurdles.
Specifically, the Form I-864 (Affidavit of Support).
This form is critical. It proves to the U.S. government that the sponsoring spouse has enough money to support the immigrant spouse, ensuring they won’t rely on public government assistance. The most important evidence you need to provide? Your tax history.
But the instructions can be confusing. Do you need one year? Three years? What if you filed late? What if you didn’t file at all?
In this comprehensive I-864 guide, we will clear up the confusion surrounding tax returns for I-864 applications in 2026. We’ll break down exactly what USCIS needs, how to avoid common mistakes, and how to get your application approved without a headache.
ℹ️ Key Takeaways
- The Rule: You are mandatory required to submit a tax return (or transcript) for the one most recent tax year.
- The Option: You may choose to submit the last three years if you believe it strengthens your case (shows financial stability), but it is optional.
- The Best Format: IRS Tax Transcripts are preferred over photocopies of your 1040 form because they are official proof of filing.
- The Income Number: Always use your “Total Income” (Adjusted Gross Income), not your gross salary, when filling out the form.
How Many Years of Tax Returns Are Required?
Let’s get straight to the answer because this is the most common question we get at Greenbroad.
According to current USCIS guidelines for 2026, you are required to submit Federal tax return information for the most recent tax year only.
What “Most Recent” Means
“Most recent” refers to the last tax year for which the filing deadline has passed.
- Example: If you are applying in July 2026, your most recent tax year is 2025 (because taxes were due April 15, 2026).
- Example: If you are applying in February 2026, your most recent tax year is likely 2024, because the deadline to file your 2025 taxes hasn’t passed yet.
The “Optional” Three Years
On the I-864 form, there is a checkbox that asks if you would like to submit information for the three most recent years.
Should you do this?
- YES, if: Your income fluctuates. If your most recent year was a little low, but the two years prior were strong, submitting three years helps demonstrate a pattern of stability.
- NO, if: Your income has been steady and clearly meets the 125% poverty guideline requirement. Sending extra paperwork that isn’t required just gives USCIS more pages to review (and potentially lose).
IRS Tax Transcripts vs. Photocopies
When gathering your tax returns for I-864, you have two format options. One is good; the other is better.
Option 1: IRS Tax Return Transcript (Recommended)
This is a printout directly from the IRS database.
- Why it’s better: It proves you actually filed the taxes. USCIS trusts this document implicitly.
- Requirement: If you submit a transcript, you do not need to submit W-2s or 1099s. The transcript has all that data summarzied.
- How to get it: You can download it instantly for free from the IRS website.
Option 2: Photocopy of Form 1040
This is a copy of the forms you filled out (or that TurboTax generated for you).
- The Risk: A photocopy proves you filled out a form, not necessarily that you filed it or paid the taxes.
- Requirement: If you choose this route, you MUST include copies of every W-2 and 1099 schedule associated with that return. If you forget a single W-2, your application could be rejected (RFE).

Income Requirements: The Magic Number
Why does USCIS care about your taxes? They need to see that the sponsor’s income meets 125% of the Federal Poverty Guidelines for their household size.
In 2026, these numbers usually adjust slightly for inflation.
- Household of 2: Requires approx. $26,000+ (Check current Poverty Guidelines 2026 - Immigration Sponsorship for exact figures).
- Household of 3: Requires approx. $33,000+.
The number USCIS looks at on your tax return is your Total Income (often the “Adjusted Gross Income” or AGI). This is crucial—do not write down your Gross Pay from your paystubs. You must match the number on your tax return exactly.

How to Fill I-864: Handling the Tax Section
When you sit down to tackle the how to fill I-864 challenge, you will eventually reach Part 6: Sponsor’s Employment and Income. Here is a simple step-by-step guide for the tax section.
Step 1: Check the Box
There is a question asking: “Have you filed a Federal income tax return for each of the three most recent tax years?”
- Answer truthfully. If you haven’t filed for all three years, you must attach an explanation (we will cover this below).
Step 2: Enter the “Total Income”
The form will ask for your “Total Income” for the most recent tax year (and the two years prior if you chose to include them).
- Where to find this number: Look at your IRS Form 1040. In recent years, this has been Line 9 or Line 11. It is labeled “Total Income.”
- Warning: Do not use “Taxable Income.” Do not use “Gross Income.” Use “Total Income.”
Step 3: Attach the Proof
Check the box indicating you are attaching a photocopy or transcript.
What If You Didn’t File Taxes?
This is a very common scenario. Perhaps you were a student, you were unemployed, or you were living abroad and didn’t earn enough to require filing.
You cannot simply leave the section blank.
If you did not file a tax return for the most recent year (or any of the required years), you must provide a written statement explaining why you were legally exempt from filing.
Valid Reasons for Not Filing:
- Income was too low: You made less than the IRS minimum threshold for filing.
- Unemployed: You had zero income.
- Certain Foreign Income: (Note: U.S. citizens usually must file even if living abroad, but there are exceptions).
The Solution:
If you didn’t file, you obviously cannot use that income to sponsor your spouse. You have two choices:
- Use Assets: Use savings, stocks, or property to make up the difference (Assets must equal 3x the income shortfall).
- Joint Sponsor: Find a friend or family member willing to be a “Joint Sponsor” who does meet the income requirements and has filed their taxes.

Common Mistakes to Avoid
We see hundreds of applications, and these are the most frequent errors regarding tax returns for I-864:
1. Submitting State Taxes Instead of Federal
USCIS is a federal agency. They do not care about your New York or California state tax returns. Only submit your Federal (IRS) returns.
2. The “Gross Income” Trap
Sponsors often look at their W-2 and write down the number from Box 1 (Wages, tips, other compensation). However, the I-864 asks for the number from your 1040 Tax Return. These numbers are often different due to deductions. Always copy the number from the 1040 form.
3. Missing Schedules
If you submit a photocopy of your tax return, you must include every single page submitted to the IRS. If you have a Schedule C (business) or Schedule D (capital gains), and you leave it out, your package is incomplete. This is why we strongly recommend using Transcripts—it avoids this error entirely.
4. Filing for the Wrong Year
If you file your I-864 in May 2026, but you send your 2024 tax return because you “haven’t gotten around” to doing your 2025 taxes yet—your application will be rejected. If the tax deadline (April 15) has passed, you must have filed your most recent taxes before submitting your green card application.
Real-World Scenarios
To help you understand how to fill I-864 correctly, let’s look at three common scenarios.
Scenario A: The Standard Employee
Sarah works as a teacher. She makes $55,000 a year.
- Requirement: She downloads her most recent IRS Transcript.
- Action: She enters her Total Income from the transcript onto the I-864. She checks the box for “one year.”
- Result: Simple, straightforward approval.
Scenario B: The Self-Employed Artist
Liam is a freelance graphic designer. His income fluctuates. Last year he made $30,000, but the year before he made $18,000.
- Requirement: Because his income is close to the poverty line limit, Liam decides to submit three years of transcripts to show an upward trend.
- Action: He carefully ensures his “Total Income” matches his “Net Profit” calculations as reported on his 1040.
- Result: The officer sees the full picture of his finances and approves.
Scenario C: The Recent College Grad
Jessica just graduated. She started a job last month making $60,000, but last year she was a student and filed no taxes.
- Requirement: She cannot provide a tax return for the most recent year because she didn’t file one.
- Action: She writes a statement: “I was not required to file a tax return in 2025 as I was a full-time student with no income.” She then includes a letter from her new employer and recent paystubs to prove her current income is sufficient.
- Result: USCIS accepts her current income evidence combined with her explanation for the missing tax return.
Conclusion
Navigating the tax returns for I-864 requirements doesn’t have to be a nightmare. Remember the golden rules:
- Focus on the most recent tax year.
- Use IRS Transcripts whenever possible.
- Be honest about your income and explain any gaps.
