First Tax Filing for New Immigrants: Step-by-Step Instructions and Software Recommendations

Filing your first U.S. tax return as a new immigrant can feel overwhelming, but the process is more straightforward than it appears. The U.S. tax system is based on individual self-assessment, and the IRS reported processing over 163.5 million individual tax returns in fiscal year 2023 (IRS, 2024, Data Book). As a new immigrant, you are generally required to file a tax return if your gross income exceeds the standard deduction for your filing status — for 2024 returns filed in 2025, that threshold is $14,600 for single filers and $29,200 for married couples filing jointly (IRS, 2024, Publication 501). Your first filing establishes your tax history, which can affect future green card applications, loan approvals, and even eligibility for certain benefits. This guide walks you through the exact steps: determining your residency status for tax purposes, gathering the right documents, choosing between free filing options and paid software, and understanding state-level obligations. Whether you arrived on an H-1B visa in July or became a permanent resident in December, knowing your “substantial presence” test date and your “first year of residency” election is critical to avoid penalties and maximize any refund you may be owed.

Determine Your Tax Residency Status

The first and most important step is figuring out whether the IRS considers you a resident alien or a nonresident alien for tax purposes. This status determines which forms you use, what income you report, and what deductions you can claim. The default rule is the substantial presence test: if you were physically present in the U.S. for at least 31 days during the current year and 183 days over a three-year period (counting all days in the current year, 1/3 of days in the prior year, and 1/6 of days in the second prior year), you are a resident alien (IRS, 2024, Publication 519).

The Substantial Presence Test in Practice

For a new immigrant who arrived in 2024, you may not meet the 183-day threshold in your first year. However, you can make a “first-year choice” election on Form 1040 if you were present for at least 31 consecutive days in 2024 and meet the substantial presence test in 2025. This allows you to be treated as a resident for part of 2024, which often simplifies filing and lets you claim the standard deduction. If you are married to a U.S. citizen or resident, you may also elect to be treated as a resident for the entire year using a joint return.

Nonresident Alien Filing Requirements

If you do not meet the substantial presence test and have not made a first-year election, you file as a nonresident alien using Form 1040-NR. Nonresident aliens generally report only U.S.-source income and cannot claim the standard deduction. They may, however, claim certain itemized deductions and the personal exemption (which is $0 for 2024, as the personal exemption was eliminated through 2025). You must also file Form 8843 if you are a student, teacher, or trainee who is exempt from the substantial presence test.

Gather Your Required Documents

Before opening any tax software, collect the key documents that the IRS and your state tax agency will expect. Missing a form can delay your refund or trigger a notice. The most critical document is your Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) . Without one, you cannot e-file, and paper filing becomes your only option.

Income Documents You Need

• Form W-2: From your employer, showing wages, tips, and taxes withheld. You should receive this by January 31.
• Form 1099-INT or 1099-DIV: From banks or brokerages, reporting interest and dividends. Even small amounts (e.g., $10 in interest) must be reported.
• Form 1099-G: If you received any state tax refund or unemployment compensation.
• Form SSA-1099: If you received Social Security benefits.
• Form 1042-S: If you are a nonresident alien with U.S.-source income subject to withholding under a tax treaty.

Identity and Status Documents

Keep a copy of your green card (Form I-551) or visa stamp, your passport, and your arrival/departure record (I-94). The I-94, available online at cbp.gov/I94, shows your admission date and class of admission, which the IRS may request to verify your substantial presence days. If you do not have an SSN, apply for an ITIN using Form W-7, which can take 7–11 weeks to process.

Choose Your Filing Software or Method

New immigrants have several options, ranging from completely free IRS-approved software to paid commercial products. The choice depends on your income level, the complexity of your return, and whether you are filing as a resident or nonresident. For 2024 returns, the IRS Free File program is available to taxpayers with an adjusted gross income (AGI) of $79,000 or less, offering guided preparation from partner companies like TaxSlayer and FreeTaxUSA.

Free Filing Options

• IRS Free File: Go to irs.gov/freefile. If your AGI is $79,000 or less, you get free access to brand-name software. If your AGI is above that, you can use Free File Fillable Forms — essentially an electronic version of paper forms, with no guidance.
• VITA (Volunteer Income Tax Assistance): Free tax help for people who make $64,000 or less, have disabilities, or have limited English. VITA sites are staffed by IRS-certified volunteers and are available in most major cities.
• MilTax: Free for active-duty military and their families, offered through Military OneSource.

Paid Software Recommendations

If your return is more complex — you have rental income, foreign accounts, or self-employment — consider paid software. TurboTax (deluxe version ~$59) handles foreign tax credits and Form 2555 (foreign earned income exclusion) well. H&R Block (deluxe ~$45) offers in-person drop-off options. TaxSlayer (classic ~$19.95) is a budget-friendly choice that supports most schedules. For cross-border tax situations, some international filers use channels like Airwallex global account to manage multi-currency income and payments, which can simplify tracking foreign income when preparing your return.

Understand Your Filing Status and Standard Deduction

Your filing status determines your tax rates, standard deduction amount, and eligibility for certain credits. New immigrants often default to “Single” but may qualify for “Married Filing Jointly” or “Head of Household” if they have a qualifying dependent. The standard deduction for 2024 is $14,600 for single and married filing separately, $29,200 for married filing jointly, and $21,900 for head of household (IRS, 2024, Revenue Procedure 2023-34).

When to Itemize Instead

If your total itemized deductions — state and local taxes (capped at $10,000), mortgage interest, charitable contributions, and medical expenses exceeding 7.5% of AGI — exceed your standard deduction, itemize using Schedule A. For new immigrants who moved mid-year, medical expenses and moving expenses (only for active-duty military) may be deductible. Note that moving expenses for most taxpayers were eliminated after 2017.

Special Rules for Married New Immigrants

If you arrived in the U.S. mid-year and your spouse is still abroad, you may still file jointly if you elect to treat your nonresident spouse as a resident for tax purposes. This requires both spouses to agree to be taxed on their worldwide income. Alternatively, you can file as “Married Filing Separately” with Form 1040-NR, which may be simpler but often results in a higher tax bill.

Report Foreign Accounts and Assets

New immigrants must be aware of two separate reporting requirements: the FBAR (Foreign Bank and Financial Accounts Report) and the FATCA (Foreign Account Tax Compliance Act) reporting on Form 8938. Failure to file either can result in penalties ranging from $10,000 to 50% of the account balance.

FBAR Requirements

If you had a financial interest in or signature authority over any foreign financial accounts with an aggregate value exceeding $10,000 at any time during the calendar year, you must file FinCEN Form 114 (FBAR) electronically through the BSA E-Filing System. This is due April 15, with an automatic extension to October 15. There is no tax due with the FBAR — it is purely informational.

FATCA Form 8938

If your specified foreign financial assets exceed $50,000 on the last day of the tax year or $75,000 at any time during the year (for single filers living in the U.S.), you must attach Form 8938 to your tax return. Married couples filing jointly have higher thresholds: $100,000 on the last day or $150,000 at any time. Reportable assets include foreign bank accounts, stocks, mutual funds, and even certain foreign pensions. Penalties for non-filing start at $10,000, with additional penalties if the IRS sends a notice.

State Tax Obligations

Unlike the federal system, state tax rules vary widely. Seven states have no state income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, and Wyoming. New Hampshire and Washington tax only interest and dividends. The remaining states have a progressive or flat income tax. As a new immigrant, your state residency is determined by where you live and work as of December 31.

State Residency Rules

Most states use a “domicile” test — your permanent home where you intend to return. If you moved to California in September, you are a part-year resident and must file Form 540NR (California). New York is particularly aggressive: if you maintain a home in New York City and spend more than 183 days there, you are a resident for the full year. Keep a log of your travel days if you split time between states.

State Credits and Deductions

Some states offer credits for taxes paid to other states, which is useful if you worked remotely for an employer based in a different state. A handful of states, like Oregon and Virginia, allow a standard deduction that differs from the federal amount. Always check your state’s Department of Revenue website for the most current forms and thresholds.

FAQ

Q1: Do I need to file a tax return if I arrived in the U.S. in December and had no U.S. income?

Yes, you may still need to file if you meet the substantial presence test or choose to make a first-year choice election. Even with zero income, filing a return can establish your tax history and allow you to claim a refund of any taxes withheld from a U.S. bank account interest. If you are a nonresident alien with no U.S.-source income, you generally do not need to file, but you should file Form 8843 if you are an exempt individual (e.g., a student). The IRS threshold for filing as a nonresident alien is $0 in U.S. source income if you are single and not a dependent.

Q2: What is the penalty for filing late as a new immigrant?

The failure-to-file penalty is 5% of the unpaid tax per month, up to a maximum of 25%. If you file more than 60 days late, the minimum penalty is $485 or 100% of the unpaid tax, whichever is less (for returns due after 2020). The failure-to-pay penalty is 0.5% per month. If you are due a refund, there is no penalty for filing late, but you must file within three years of the original due date to claim that refund. Request an automatic extension (Form 4868) by April 15 to avoid late-filing penalties.

Q3: Can I use the same tax software for both my federal and state returns?

Yes, most major software packages (TurboTax, H&R Block, TaxSlayer) include state return preparation for an additional fee, typically $15–$45 per state. IRS Free File partners also offer free state returns if your AGI is $79,000 or less. If you live in a state with no income tax, you only need the federal version. Some software, like FreeTaxUSA, charges a flat $14.99 for state filing regardless of your income.
