Married Filing Jointly vs Separately for Immigrant Couples

The Direct Answer

Most immigrant couples pay less tax filing Married Filing Jointly (MFJ) than Married Filing Separately (MFS). The MFJ standard deduction for 2024 is $29,200 - double the $14,600 MFS amount - and MFJ filers retain access to valuable credits that MFS filers cannot claim. The main exception is mixed-status couples where one spouse is a nonresident alien, which requires a specific IRS election.

MFJ vs MFS: Quick Comparison

When MFJ Benefits Immigrant Couples Most

Filing jointly typically produces a lower tax bill when:

• Both spouses earn similar incomes (reduces the "marriage penalty" effect)
• The couple has children and wants to claim the Child Tax Credit or Child and Dependent Care Credit
• One spouse has little or no US income (the other spouse's income benefits from a wider tax bracket)
• The couple qualifies for the Earned Income Credit

When MFS May Be the Better Choice

Married Filing Separately can make sense in specific situations:

• One spouse has large medical expenses (deductible above 7.5% of adjusted gross income - a lower individual income makes this threshold easier to exceed)
• One spouse has significant foreign income that is excluded under Form 2555 or offset by foreign tax credits
• The couple is legally separating or has disputes about shared tax liability
• Immigration counsel has advised keeping financial filings separate

Note: if one spouse itemizes deductions on MFS, the other spouse must also itemize - they cannot take the standard deduction.

Mixed-Status Couples: One Spouse Is a Nonresident Alien

This is the most complex situation for immigrant couples. If your spouse does not meet the Green Card Test or the Substantial Presence Test, they are a nonresident alien (NRA) by default.

Default Treatment

Without any election, a US resident married to an NRA must file as Married Filing Separately. The NRA spouse is taxed only on US-source income.

The Section 6013(g) Election

You can make a one-time election under IRC Section 6013(g) to treat your NRA spouse as a US resident for the full year. This allows you to file MFJ and access the full standard deduction and all joint credits.

The trade-off: your spouse's worldwide income becomes subject to US tax for that year and all future years (until you revoke the election). This matters if your spouse has substantial income from their home country.

How to Make the Election

1. Both spouses sign a statement including their names, addresses, and tax identification numbers
2. Attach the statement to your timely filed (including extensions) Form 1040
3. The statement must declare you are making the election under Section 6013(g)

The election is irrevocable for the tax year it is made. You can revoke it in a subsequent year.

Common Immigrant Scenarios

H-1B holder married to a spouse on F-1 visa: The F-1 spouse is generally a nonresident alien during the first 5 years. You may need the Section 6013(g) election to file jointly.

Permanent resident married to a citizen of another country who lives abroad: The foreign spouse may be an NRA. Filing separately is default; Section 6013(g) is optional if the worldwide income inclusion is manageable.

Two immigrants both in the US on work visas: If both pass the Substantial Presence Test, both are treated as resident aliens and can file MFJ without any special election.
