Attach a statement explaining your eligibility.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nWhy Your 2026 US Tax Filing Deserves Extra Attention<\/h3>\nStronger Enforcement on Foreign Bank Accounts<\/h4>\nEnforcement of FATCA (the Foreign Account Tax Compliance Act) and FBAR reporting has grown, supported by data-sharing agreements between the US and banks around the world. If you hold savings, investment, or pension accounts in your home country or elsewhere, those accounts are increasingly visible to the IRS whether or not you report them.<\/p>\n Low-Cost and Free Filing Options<\/h4>\nThe IRS continues to steer eligible taxpayers toward electronic filing, including free options for lower- and moderate-income households. Availability changes from season to season, so check IRS.gov for what is offered this year before paying for commercial tax preparation.<\/p>\n Your Tax Record Can Affect Your Immigration Case<\/h4>\nImmigration benefit decisions can touch on financial history. An unfiled or inaccurate tax return can complicate visa renewals, employment-based green card applications, and naturalization in ways that go beyond an IRS penalty notice. If you are managing an investor or employment visa alongside a US business, working with a CPA who specialises in foreign-owned US companies is often a sound investment. Our guide, Best CPAs for Foreign-Owned US Businesses in 2026: Tax Filing, FATCA, and ITIN Help, covers what to look for.<\/p>\n Step 1: Confirm Whether You Are Legally Required to File<\/h3>\nYour filing obligation depends on three things: your tax residency status, your filing status, and your gross income.<\/p>\n Resident Alien vs Non-Resident Alien: The Test That Decides Your Tax Bill<\/h4>\nThe IRS does not use your visa category to decide how to tax you. It applies two tests.<\/p>\n Green Card Test:<\/strong> If you held a lawful permanent resident card at any point during the tax year, you are a resident alien for tax purposes.<\/p>\nSubstantial Presence Test (SPT):<\/strong> You meet this test if you were physically present in the US for at least 31 days in the current year, and at least 183 days when you add all days in the current year, one-third of the days in the prior year, and one-sixth of the days in the year before that.<\/p>\n\n \n\n\n| Category<\/th>\n | Form to File<\/th>\n | Income Taxed<\/th>\n<\/tr>\n<\/thead>\n | \n\n| US Citizen<\/td>\n | Form 1040<\/td>\n | Worldwide income<\/td>\n<\/tr>\n | \n| Resident Alien (Green Card or SPT)<\/td>\n | Form 1040<\/td>\n | Worldwide income<\/td>\n<\/tr>\n | \n| Non-Resident Alien<\/td>\n | Form 1040-NR<\/td>\n | US-source and effectively connected income only<\/td>\n<\/tr>\n | \n| Dual-Status Filer<\/td>\n | Combination (see IRS Publication 519)<\/td>\n | Varies by period<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n If you arrived mid-year and crossed the SPT threshold, you may be a dual-status alien: a resident for part of the year and a non-resident for the rest. This is one of the more complex areas of US tax law, and the fee for a specialist CPA is usually far lower than the cost of an error.<\/p>\n Income Thresholds, and Why Filing Can Pay Even When It Is Optional<\/h4>\nThe IRS sets minimum gross income levels below which most people do not need to file. These thresholds change annually and depend on filing status and age. Check IRS Publication 501 or the current Form 1040 instructions.<\/p>\n Even if your income is below the threshold, filing is often worthwhile. If federal income tax was withheld from your paycheck, filing a return is the only way to get that money back. Refundable tax credits work the same way and can produce a refund larger than the tax you paid.<\/p>\n Step 2: Get Your SSN or ITIN Before You File<\/h3>\nEvery US tax return requires either a Social Security Number (SSN) or an Individual Taxpayer Identification Number (ITIN).<\/p>\n \n- SSN:<\/strong> Issued by the Social Security Administration to citizens, permanent residents, and visa holders authorised to work in the US.<\/li>\n
- ITIN:<\/strong> Issued by the IRS through Form W-7 to people who are not eligible for an SSN but have a US tax filing requirement, including non-resident aliens with US income and dependants claimed on a return. For a full walkthrough, see our ITIN Application Process for Business Owners 2026 guide.<\/li>\n<\/ul>\n
An ITIN is a tax processing number only. It does not authorise employment, does not grant immigration status, and does not qualify you for Social Security benefits. Some tax credits, including the Earned Income Tax Credit, require a valid SSN for the taxpayer and each qualifying child.<\/p>\n Step 3: Gather Your Tax Documents Before Opening Any Software<\/h3>\nJumping into tax preparation software without your paperwork is one of the most common causes of costly errors and amended returns. Collect these first.<\/p>\n Income Documents<\/h4>\n\n- Form W-2:<\/strong> Wages from US employers, usually issued by late January<\/li>\n
- Form 1099-NEC \/ 1099-MISC:<\/strong> Freelance, contract, or miscellaneous income<\/li>\n
- Form 1099-INT \/ 1099-DIV:<\/strong> Interest and dividends from US bank and brokerage accounts<\/li>\n
- Form 1099-B:<\/strong> Proceeds from selling stocks or other investments<\/li>\n
- Form 1042-S:<\/strong> Income paid to non-resident aliens subject to withholding, often from employers, universities, or financial institutions<\/li>\n
- Foreign income records:<\/strong> Pay slips, bank statements, or employer letters for income earned abroad, needed by resident aliens reporting worldwide income<\/li>\n<\/ul>\n
Deduction and Tax Credit Documents<\/h4>\n\n- Mortgage interest statements (Form 1098) if you own a home<\/li>\n
- Student loan interest statements<\/li>\n
- Charitable donation receipts<\/li>\n
- Health insurance premium records, if you are claiming the premium tax credit<\/li>\n
- Records of state and local taxes paid, for the SALT deduction<\/li>\n
- Business expense records if you are self-employed<\/li>\n<\/ul>\n
Prior-Year Information<\/h4>\n\n- Last year’s tax return, especially your Adjusted Gross Income, which the IRS uses to verify your identity when you e-file<\/li>\n
- Any IRS notices received during the year<\/li>\n<\/ul>\n
Foreign Account Information<\/h4>\n\n- Account numbers, bank or institution names, and maximum balances for every foreign bank or investment account, needed for the FBAR (FinCEN Form 114) and possibly Form 8938<\/li>\n<\/ul>\n
Step 4: Choose the Right IRS Form and Schedules<\/h3>\nThe Main Return<\/h4>\nResident aliens and US citizens file Form 1040<\/strong>. The old 1040-EZ and 1040-A no longer exist; everyone uses the same base form, with different schedules attached.<\/p>\nNon-resident aliens file Form 1040-NR<\/strong>, which is structured around the income categories taxed for non-residents.<\/p>\nKey Schedules to Know<\/h4>\n\n \n\n\n| Schedule<\/th>\n | Purpose<\/th>\n | Common Filers<\/th>\n<\/tr>\n<\/thead>\n | \n\n| Schedule B<\/td>\n | Interest and ordinary dividends<\/td>\n | Anyone with more than $1,500 in interest or dividends, or with foreign accounts<\/td>\n<\/tr>\n | \n| Schedule C<\/td>\n | Profit or loss from self-employment<\/td>\n | Freelancers, gig workers, sole proprietors<\/td>\n<\/tr>\n | \n| Schedule D<\/td>\n | Capital gains and losses<\/td>\n | Anyone who sold stocks, crypto, or property<\/td>\n<\/tr>\n | \n| Schedule E<\/td>\n | Rental income, partnerships, S-corps<\/td>\n | Landlords, LLC and partnership members<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n If you own a US LLC or corporation, the business tax return is separate from your personal return. See How to File US Business Taxes as a Non-Resident Owner in 2026: Form 5472, 1120, and Penalties Explained.<\/p>\n Step 5: Calculate Taxable Income, Tax Credits, and Your Refund<\/h3>\nThis is where most refunds are won or lost.<\/p>\n \n- Total gross income:<\/strong> All income from all sources, worldwide for citizens and resident aliens.<\/li>\n
- Above-the-line deductions:<\/strong> Subtract eligible adjustments such as student loan interest, contributions to certain retirement accounts, and half of self-employment tax. The result is your Adjusted Gross Income (AGI).<\/li>\n
- Standard or itemised deduction:<\/strong> Subtract whichever is larger. The standard deduction adjusts for inflation each year; confirm the current amount in the Form 1040 instructions. Non-resident aliens generally cannot claim it and must itemise on Schedule A.<\/li>\n
- Taxable income:<\/strong> AGI minus deductions, and any qualified business income deduction if you qualify.<\/li>\n
- Tax calculated:<\/strong> Apply the current federal tax brackets, published in the Form 1040 instructions.<\/li>\n
- Tax credits:<\/strong> Subtract credits such as the child tax credit, education credits, and the foreign tax credit. Credits reduce your tax dollar for dollar, so they are usually worth more than deductions.<\/li>\n
- Payments already made:<\/strong> Subtract withholding from your W-2 or 1099 and any estimated tax payments.<\/li>\n
- Refund or balance due:<\/strong> The difference is either refunded to you or payable by the deadline.<\/li>\n<\/ol>\n
Illustrative Example: H-1B Employee Claiming a Tax Refund<\/h4>\nIllustrative only. Figures are hypothetical, use an older standard deduction for simplicity, and are not tax advice.<\/em><\/p>\nAisha is on an H-1B visa and was in the US for the full year, so she passes the Substantial Presence Test and files as a resident alien.<\/p>\n \n \n\n\n| Item<\/th>\n | Amount<\/th>\n<\/tr>\n<\/thead>\n | \n\n| Wages (W-2 Box 1)<\/td>\n | $72,000<\/td>\n<\/tr>\n | \n| Interest income (1099-INT)<\/td>\n | $400<\/td>\n<\/tr>\n | \n| Gross income<\/td>\n | $72,400<\/td>\n<\/tr>\n | \n| Student loan interest deduction<\/td>\n | \u2013$1,800<\/td>\n<\/tr>\n | \n| AGI<\/td>\n | $70,600<\/td>\n<\/tr>\n | \n| Standard deduction (illustrative)<\/td>\n | \u2013$14,600<\/td>\n<\/tr>\n | \n| Taxable income<\/td>\n | $56,000<\/td>\n<\/tr>\n | \n| Tax calculated<\/td>\n | about $7,400<\/td>\n<\/tr>\n | \n| Federal tax withheld (W-2 Box 2)<\/td>\n | $8,500<\/td>\n<\/tr>\n | \nRefund<\/strong><\/td>\n| about $1,100<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n Aisha files Form 1040 and receives a refund. Without the student loan interest deduction, her refund would have been several hundred dollars smaller.<\/p>\n Illustrative Example: Freelancer With Foreign Clients and a Foreign Bank Account<\/h4>\nIllustrative only.<\/em><\/p>\nMarco holds an O-1 visa, passes the SPT, and does freelance video production for US and overseas clients. He keeps a bank account in his home country.<\/p>\n \n \n\n\n| Item<\/th>\n | Amount<\/th>\n<\/tr>\n<\/thead>\n | \n\n| US client income (1099-NEC)<\/td>\n | $55,000<\/td>\n<\/tr>\n | \n| Foreign client income (no withholding)<\/td>\n | $18,000<\/td>\n<\/tr>\n | \n| Gross income (worldwide)<\/td>\n | $73,000<\/td>\n<\/tr>\n | \n| Deductible half of self-employment tax<\/td>\n | about \u2013$5,150<\/td>\n<\/tr>\n | \n| AGI<\/td>\n | about $67,850<\/td>\n<\/tr>\n | \n| Standard deduction (illustrative)<\/td>\n | \u2013$14,600<\/td>\n<\/tr>\n | \n| Taxable income (before any QBI deduction)<\/td>\n | about $53,250<\/td>\n<\/tr>\n | \n| Income tax calculated<\/td>\n | about $6,800<\/td>\n<\/tr>\n | \n| Self-employment tax (Schedule SE)<\/td>\n | about $10,300<\/td>\n<\/tr>\n | \n| Foreign tax credit (Form 1116)<\/td>\n | \u2013$2,100<\/td>\n<\/tr>\n | \n| Total tax after credit<\/td>\n | about $15,000<\/td>\n<\/tr>\n | \n| Estimated payments made<\/td>\n | $12,000<\/td>\n<\/tr>\n | \nBalance due at filing<\/strong><\/td>\n| about $3,000<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n Marco files Form 1040 with Schedules B, C, and SE plus Form 1116. If his foreign account’s maximum balance crossed the FBAR threshold at any point in the year, he must also file an FBAR separately through FinCEN.<\/p>\n Step 6: File Your Return With Free File, Tax Software, or a CPA<\/h3>\nE-Filing vs Paper Filing<\/h4>\nElectronic filing is faster, more accurate, and gets refunds to your bank account sooner.<\/p>\n \n- IRS Free File:<\/strong> Free guided tax software for filers under an income limit. Check eligibility at IRS.gov.<\/li>\n
- IRS free e-file tools:<\/strong> The IRS’s own options change from year to year. Confirm what is available for the current season.<\/li>\n
- Commercial tax software:<\/strong> Products such as TurboTax, H&R Block, and TaxAct handle more complex returns but charge for certain forms and features. Not all of them support Form 1040-NR.<\/li>\n
- Tax professional:<\/strong> A CPA, IRS enrolled agent, or licensed tax preparer. Especially valuable for non-resident returns, treaty claims, FATCA and FBAR reporting, or self-employment with foreign income.<\/li>\n
- Paper filing:<\/strong> Still accepted but slower and more error-prone. Some non-resident and amended returns may still require it.<\/li>\n<\/ul>\n
Signing Your Return<\/h4>\nAn e-filed return is signed using your prior-year AGI or an IRS-issued Identity Protection PIN. A paper return needs a handwritten signature. An unsigned return is invalid.<\/p>\n How to Pay Tax Owed and IRS Payment Plan Options<\/h4>\nPayment is due by the original deadline, even if you have an extension to file.<\/p>\n \n- IRS Direct Pay by bank transfer, with no fee<\/li>\n
- Debit or credit card, through a processor that charges a fee<\/li>\n
- Electronic funds withdrawal when you e-file<\/li>\n
- Check or money order with Form 1040-V<\/li>\n
- IRS Online Account, where you can request an installment agreement if you cannot pay in full<\/li>\n<\/ul>\n
If you cannot pay the full balance, setting up an IRS payment plan is almost always better than not filing. Failing to file adds its own penalty on top of the unpaid tax.<\/p>\n Step 7: FBAR and FATCA Reporting for Foreign Bank Accounts<\/h3>\nThis step sits outside your tax return but is closely tied to it, and it is where penalties become expensive fastest.<\/p>\n FBAR (FinCEN Form 114)<\/h4>\nIf you had a financial interest in, or signature authority over, foreign financial accounts whose combined maximum value exceeded the threshold at any time during the year (confirm the current figure at fincen.gov), you must file an FBAR. It is submitted through FinCEN’s BSA E-Filing System, not the IRS. It is due on the same date as your tax return, with an automatic extension to October.<\/p>\n Form 8938 (FATCA)<\/h4>\nIf your foreign financial assets exceed the Form 8938 thresholds, which vary by filing status and by whether you live in or outside the US, you attach Form 8938 to your tax return. FBAR and Form 8938 overlap but do not replace each other. Many filers need both.<\/p>\n Step 8: Extensions, Deadlines, and Late Filing Penalties<\/h3>\nAn extension to file is not an extension to pay. If you expect to owe, estimate the amount and pay by the original deadline to limit failure-to-pay penalties and interest. Form 4868 gives you six extra months to file only.<\/p>\n Costly Tax Filing Mistakes Immigrants Make<\/h3>\n1. Filing as a non-resident when you are a resident alien.<\/strong> Run the Substantial Presence Test before choosing your form. If you arrived mid-year, count your days carefully using IRS Publication 519.<\/p>\n2. Leaving out foreign income.<\/strong> Resident aliens must report worldwide income. Salary, freelance pay, rental income, or pension income from abroad belongs on your return even if the money never entered a US bank account.<\/p>\n3. Missing the FBAR or Form 8938.<\/strong> Add a foreign account check to your filing routine. Penalties for not filing can far exceed any tax you might have saved.<\/p>\n4. Claiming the standard deduction as a non-resident alien.<\/strong> With limited treaty exceptions, non-resident aliens must itemise. Review Schedule A and Publication 519.<\/p>\n5. Using an expired ITIN.<\/strong> An ITIN not used on a federal return for three consecutive years expires. Renew with Form W-7 well before filing season to avoid refund delays.<\/p>\n6. Not keeping proof of foreign tax paid.<\/strong> If you paid income tax to another country, you may qualify for the foreign tax credit on Form 1116, which directly lowers your US tax bill. Without records, you cannot claim it.<\/p>\n7. Ignoring state income tax.<\/strong> Most states with an income tax require a separate return. Check the revenue department website for every state where you lived or worked.<\/p>\n8. Filing late out of uncertainty.<\/strong> File an imperfect return on time and correct it later with Form 1040-X. Penalties for not filing are generally harsher than those for honest errors you fix.<\/p>\nHow Your Visa Status Affects Tax Residency and Immigration Applications<\/h3>\nYour visa does not decide your tax residency, the SPT and Green Card Test do, but it provides important context.<\/p>\n H-1B, L-1, and O-1 Work Visa Holders<\/h4>\nWorkers present for a full year almost always pass the SPT and file Form 1040 as resident aliens.<\/p>\n F-1 and J-1 International Students and Scholars<\/h4>\nStudents and exchange visitors are “exempt individuals” under the SPT for a limited number of years, so their days in the US do not count during that period. Many F-1 students in their first five calendar years file Form 1040-NR as non-residents. Scholarship and fellowship income may be taxable or treaty-exempt depending on your country and how the funds are used.<\/p>\n E-2 Treaty Investor Visa Holders<\/h4>\nE-2 investors often deal with business income, treaty questions, and the interaction between investor status and tax residency, particularly when running a US company.<\/p>\n Green Card Holders<\/h4>\nPermanent residents are resident aliens taxed on worldwide income, including years spent mostly abroad, unless they formally give up their green card.<\/p>\n If you are pursuing an employment-based green card while on a work visa, clean and consistent tax filings matter, since tax transcripts are sometimes requested during immigration processing.<\/p>\n If you are still planning your move, understanding your full cost of living helps you budget for taxes and savings. Our guide to Affordable Co-Living Spaces in the USA for New Residents is a practical place to start.<\/p>\n State Income Tax Returns: The Second Filing Most Immigrants Forget<\/h3>\nMost states with a personal income tax require their own return. Rules on who must file, what income counts, and which deductions and credits apply vary widely.<\/p>\n Florida, Texas, and Nevada have no personal income tax. California, New York, and Massachusetts have significant state taxes and active enforcement.<\/p>\n If you moved between states during the year, you may need part-year resident returns in more than one state. If you worked remotely for an employer based in another state, that state may also claim tax on your income. Raise state tax early with any tax professional you hire.<\/p>\n Business owners also face entity-level filings and franchise taxes. See our Annual Report & Franchise Tax by State: 2026 Guide.<\/p>\n When to Hire an International Tax CPA or IRS Enrolled Agent<\/h3>\nA Certified Public Accountant or IRS Enrolled Agent with cross-border experience is worth the fee if any of these apply:<\/p>\n \n- You are a non-resident alien or dual-status filer<\/li>\n
- You earn income in more than one country<\/li>\n
- You are claiming a tax treaty benefit<\/li>\n
- You hold foreign accounts or assets above reporting thresholds<\/li>\n
- You own part of a foreign corporation or partnership<\/li>\n
- You are self-employed with international clients<\/li>\n
- You received a large inheritance or gift from abroad<\/li>\n
- You have unfiled prior-year returns to bring into compliance<\/li>\n<\/ul>\n
If cost is a concern, the IRS Volunteer Income Tax Assistance (VITA) programme offers free basic tax preparation for eligible filers, and some sites have volunteers trained in non-resident returns. Find a location on IRS.gov.<\/p>\n Amended Returns: Fixing Errors With Form 1040-X<\/h3>\nIf you discover an error after filing, such as missing income, a wrong deduction, or an omitted form, file Form 1040-X. To claim a refund, you generally have three years from the date you filed or two years from the date you paid, whichever is later. If you owe more, amend as soon as possible, since interest and penalties run from the original due date.<\/p>\n Non-resident filers also use Form 1040-X, indicating the original form filed. If you are amending to claim a treaty benefit you missed, get specialist advice.<\/p>\n How Long to Keep Tax Records<\/h3>\nThe IRS generally has three years from filing to audit a return, six years if more than 25% of gross income was omitted, and no time limit where fraud is involved or no return was filed. Special rules can apply to foreign-related filings. As a practical rule:<\/p>\n | | | | | | |
