You do not automatically need a separate return for a joint brokerage account, but without a valid joint resident election you may need Form 1040-NR for your filing status and your legally allocated taxable investment income.
“I am a G4 visa holder married to a US citizen, and we have a joint brokerage account funded mostly by my salary. My husband reports all of it on his tax return and I do not file. Should I have been filing and paying tax on this account separately?”
Summary
Your husband’s reporting may already be correct if you made a valid resident election and filed one joint return. If you did not, the problem is still fixable year by year by allocating the account correctly and filing or amending only the returns the IRS rules require.
Your answer depends first on whether you and your husband made a federal and filed jointly, and then—if you did not—on who owned each investment item and what kind of income it produced.
If the return says “married filing jointly” and you made the required , that was your return too—not only your husband’s. Both spouses are treated as U.S. residents and report their worldwide income on the joint return, so you do not file a separate return merely for this brokerage account (IRS “Nonresident spouse,” IRC §6013(g) guidance).
Ordinary G-4 days do not count toward the substantial-presence test, so this normally leaves you a unless another residency rule applies. File Form 1040-NR if you were engaged or considered engaged in a U.S. trade or business—even if your income was exempt—or, if not engaged, when your allocated taxable U.S.-source income was not fully covered by withholding. U.S.-corporation dividends are generally U.S.-source and subject to 30% or a lower treaty rate; qualifying bank-deposit or portfolio interest can be exempt; and net U.S.-source capital gains have the separate 183-day rule (Form 8843; IRS Publication 519 (2025); 2025 Instructions for Form 1040-NR).
After the first election year, the IRS permits joint or separate returns while the election remains effective. You remain a U.S. resident for federal income-tax purposes and must report your worldwide income on the appropriate resident return; the brokerage allocation follows ownership and applicable community-property rules (IRS “Nonresident spouse”; Publication 555).
That treatment is not automatically correct merely because the brokerage issued the 1099 under his taxpayer number. It works only to the extent the income was legally his; amounts belonging to you require allocation, and the named recipient may have reporting duties (2025 General Instructions for Certain Information Returns; Publication 555).
Ordinary G-4 status excludes your days from the substantial-presence test and does not require Form 8843, but it does not itself exempt investment income.

Next steps
These steps determine your status first, allocate the account second, and correct only the affected years.
Start with filing status
Classify every filed tax year
For each year, mark one of three cases: valid married-filing-jointly return with a ; later separate returns while that election remained effective; or no election and treatment. The first election year required a joint return and a statement signed by both spouses containing the declaration and each spouse’s name, address, and identification number. The governing instructions are at https://www.irs.gov/individuals/international-taxpayers/nonresident-spouse.
Requirements
Before calculating tax
Allocate each brokerage item
If the return was joint, include both spouses’ reportable account income once on that return. If returns were separate, determine community and separate income under Publication 555 at https://www.irs.gov/pub/irs-pdf/p555.pdf; state domicile law governs the classification, and its special nonresident-spouse rule applies when no resident election was made. Do not use the taxpayer number printed on the 1099 as the ownership answer.
Requirements
Only for no-election years
Apply the nonresident income rules
Classify your allocated items using Publication 519 at https://www.irs.gov/publications/p519: domestic-corporation dividends are generally U.S.-source and subject to 30% or a lower treaty rate; qualifying bank-deposit and portfolio interest can be exempt; and net U.S.-source capital gains use the 183-day rule. Separately determine whether you were engaged or considered engaged in a U.S. trade or business, because that status can require Form 1040-NR even when income is exempt.
Requirements
File now for overdue years
File the required returns and corrections
For a no-election year, file Form 1040-NR when either filing trigger in its instructions applies; use https://www.irs.gov/instructions/i1040nr. A calendar-year return is generally due April 15 when you receive wages subject to U.S. income-tax withholding and June 15 when you do not; the 2025 no-withheld-wage deadline was June 15, 2026. If your husband’s separate return included income allocable to you, he files Form 1040-X through https://www.irs.gov/filing/file-an-amended-return, and the person named on the original 1099 files the same type of nominee Form 1099 for your amount under https://www.irs.gov/instructions/i1099gi. If choosing resident treatment retroactively, file a joint Form 1040-X within the later of three years after the original return or two years after payment, and amend later affected returns.
Requirements
Legal sources
This answer is based on IRS Form 8843, Publications 519 and 555, Form 1040-NR and information-return instructions, and the IRS’s spousal-election and amendment guidance.
2025 Form 8843
A regular G-4 holder is an exempt individual for substantial-presence purposes and does not file Form 8843 solely to exclude those days.
General Instructions—Who Must File; Exempt Individuals
The term “exempt individual” also includes an individual temporarily present in the United States as a foreign government-related individual under an “A” or “G” visa, other than individuals holding “A-3” or “G-5” class visas. If you are present under any other “A” or “G” class visa, you are not required to file Form 8843.
IRC 6013(g) IRS guidance
A valid spousal election makes both spouses U.S. residents for federal income tax and requires a joint return in the election year.
Nonresident Spouse Treated as a Resident
You and your spouse are treated, for federal income tax purposes, as U.S residents for all tax years that the choice is in effect. You must file a joint income tax return for the year you make the choice (but you and your spouse can file joint or separate returns in later years). Each spouse must report their entire worldwide income for the year you make the choice and for all later years unless the choice is ended or suspended. However, you can also make the choice by filing a joint amended return on Form 1040X, Amended U.S. Individual Income Tax Return within 3 years from the date you filed your original U.S. income tax return or 2 years from the date you paid your income tax for that year, whichever is later.
IRS international-organization employee guidance
A qualifying international-organization compensation exemption does not shelter separate investment returns.
Employees of international organizations
The tax exemptions described above apply only to compensation you receive for official services performed for the foreign government or international organization. These tax exemptions do not apply to any other U.S. source income you may earn such as interest, dividends, rents, or royalties.
IRS Publication 519 (2025)
Domestic-corporation dividends are generally U.S.-source income, while the nonresident FDAP rate is generally 30% unless a treaty lowers it.
Chapter 2—Dividends; Chapter 4—The 30% Tax
In most cases, dividend income received from domestic corporations is U.S. source income. The 30% (or lower treaty) rate applies to the gross amount of U.S. source fixed, determinable, annual, or periodical (FDAP) gains, profits, or income. Interest income that is not connected with a U.S. trade or business is excluded from income if it is from: Deposits (including certificates of deposit) with persons in the banking business;
IRS Publication 519 (2025)
Nonresident capital-gain taxation turns on U.S. source, tax home, and physical presence for at least 183 days.
Chapter 4—183-day rule; Chapter 2—Personal Property
If you were in the United States for 183 days or more during the tax year, your net gain from sales or exchanges of capital assets is taxed at a 30% (or lower treaty) rate. If you were in the United States for less than 183 days during the tax year, capital gains (other than gains listed earlier) are tax exempt unless they are effectively connected with a trade or business in the United States during your tax year. Gain or loss from the sale or exchange of personal property generally has its source in the United States if you have a tax home in the United States. If you do not have a tax home in the United States, the gain or loss is generally considered to be from sources outside the United States.
2025 Instructions for Form 1040-NR
The instructions distinguish nonresidents engaged in a U.S. trade or business from those whose filing duty depends on unsatisfied tax on U.S.-source income.
Who Must File; When To File
A nonresident alien individual engaged or considered to be engaged in a trade or business in the United States during 2025. You must file even if: Your income did not come from a trade or business conducted in the United States, You have no income from U.S. sources, or Your income is exempt from income tax. You were a nonresident alien not engaged in a trade or business in the United States during 2025 and: a. You received income from U.S. sources that is reportable on Schedule NEC, lines 1 through 12; and b. Not all of the U.S. tax that you owe was withheld from that income. If you didn’t receive wages as an employee subject to U.S. income tax withholding, file Form 1040-NR by the 15th day of the 6th month after your tax year ends. A return for the 2025 calendar year is due by June 15, 2026.
IRS Publication 555
When no resident election exists, special nonresident-spouse community-income rules apply and state domicile law matters.
Nonresident alien spouse
If you are a U.S. citizen or resident alien and don't choose to treat your nonresident alien spouse as a U.S. resident for tax purposes, treat your community income as explained next under Spouses living apart all year. However, you don't have to meet the four conditions discussed there. Generally, the laws of the state in which you are domiciled govern whether you have community property and community income or separate property and separate income for federal tax purposes.
General Instructions for Certain Information Returns (2025)
The person named on a 1099 must issue nominee forms when some reported income actually belongs to another owner.
Nominee/middleman returns
Generally, if you receive a Form 1099 for amounts that actually belong to another person, you are considered a nominee recipient. You must file a Form 1099 with the IRS (the same type of Form 1099 you received) for each of the other owners showing the amounts allocable to each. You must also furnish a Form 1099 to each of the other owners.
Form 1040-X IRS guidance
Form 1040-X corrects an individual return, while refund claims have the three-year/two-year time limit.
To amend a return, file Form 1040-X, Amended U.S. Individual Income Tax Return. Generally, to claim a refund, you must file an amended return within 3 years after the date you filed your original return or 2 years after the date you paid the tax, whichever is later. You can use tax software to electronically file your 1040-X online.
These are the official IRS rules for the cited tax years and update dates; tax rules and annual forms can change.
