Are There Benefits to Filing Jointly?

Married couples typically choose between filing separately or filing jointly. Filing as “married filing jointly” means a couple combines their incomes, deductions, and credits on a single tax return. This approach is a common choice for many married couples. It consolidates financial reporting for both spouses onto one form, simplifying tax preparation.

Eligibility for Joint Filing

To qualify for married filing jointly status, a couple must be considered married as of the last day of the tax year. This means the marriage is recognized under federal and state law. If legally separated by a divorce or separate maintenance decree by year-end, they generally cannot file jointly. However, individuals separated without a formal decree may still be considered married for tax purposes.

If one spouse passes away during the tax year, the surviving spouse can still file a joint return for that year. For the two tax years following the spouse’s death, a qualifying widow(er) status may be available, providing similar tax advantages.

Tax Rate Advantages

Joint filers often find advantages in their overall tax liability. One benefit is the standard deduction, which for married filing jointly filers is higher than for individuals. For 2024, the standard deduction for married couples filing jointly is $29,200. This reduces the combined taxable income, potentially leading to a lower tax obligation compared to filing separately.

Tax brackets also offer an advantage for joint filers. Income thresholds are generally twice as wide for married couples filing jointly compared to single filers. This allows a larger portion of a couple’s combined income to be taxed at lower rates before reaching higher brackets. For example, a combined income that might push a single filer into a higher tax bracket could remain in a lower bracket on a joint return.

Joint filing creates an income-splitting effect. If one spouse earns more than the other, combining incomes can result in a lower overall tax burden than if they filed two separate returns. The higher earner’s income is averaged with the lower earner’s, allowing more combined earnings to be taxed at lower joint rates.

Access to Tax Credits

Filing jointly can enhance a couple’s ability to access various tax credits, which directly reduce the amount of tax owed. The Child Tax Credit (CTC) provides up to $2,000 per qualifying child for the 2024 tax year, with a refundable portion known as the Additional Child Tax Credit (ACTC) potentially providing up to $1,700 per child. Joint filing allows couples with higher combined incomes to claim the full credit amount, as the credit begins to phase out for married couples filing jointly only when their modified adjusted gross income exceeds $400,000. Filing separately could cause one spouse to lose eligibility or receive a reduced credit if their individual income exceeds lower thresholds.

The Earned Income Tax Credit (EITC) is another credit that can be more accessible or provide a larger benefit for joint filers. This credit supports low-to-moderate-income working individuals and families. The maximum credit amount and the income thresholds for eligibility are higher for married couples filing jointly, especially for those with qualifying children. For example, for the 2024 tax year, married couples filing jointly with three or more children can qualify with an earned income of up to $66,819.

Education credits, such as the American Opportunity Tax Credit (AOTC) and the Lifetime Learning Credit (LLC), also have more favorable income limitations for joint filers. The AOTC offers a maximum annual credit of $2,500 per eligible student for the first four years of higher education. For the 2024 tax year, the AOTC begins to phase out for joint filers when their modified adjusted gross income is between $160,000 and $180,000. Similarly, the Lifetime Learning Credit, which offers up to $2,000 per tax return, has a phase-out range for joint filers between $160,000 and $180,000 in modified adjusted gross income for 2024.

The Child and Dependent Care Credit allows taxpayers to claim a credit for expenses paid for the care of a qualifying person to enable the taxpayer (and spouse, if filing jointly) to work or look for work. For 2024, the maximum eligible expenses are $3,000 for one qualifying person and $6,000 for two or more. The credit amount ranges from 20% to 35% of these expenses, depending on income. This credit is typically claimed on a joint return, ensuring that the work-related expenses of both spouses are considered.

Other Financial Advantages

Beyond direct tax rate and credit benefits, filing jointly can offer other financial advantages for married couples. One relates to Individual Retirement Arrangements (IRAs). For 2024, individuals can contribute up to $7,000 to an IRA, or $8,000 if age 50 or older. A key advantage for joint filers is the ability to contribute to a spousal IRA. This means that even if one spouse has little or no earned income, the working spouse can contribute to an IRA on behalf of the non-working spouse, allowing the couple to make two IRA contributions and double their tax-advantaged retirement savings.

The deduction for capital losses also presents a more favorable limit for joint filers. For 2024, this deduction limit is $3,000 for married couples filing jointly. This is double the $1,500 limit allowed for those married filing separately.

The student loan interest deduction is another area where joint filing can provide a financial edge. Taxpayers can deduct up to $2,500 in student loan interest paid during the year. For 2024, the income phase-out for this deduction is more generous for joint filers, beginning when their modified adjusted gross income is $165,000 and disappearing entirely at $195,000.

Lastly, the deductibility of contributions to Traditional IRAs can be affected by filing status and workplace retirement plan coverage. If one spouse is covered by a workplace retirement plan but the other is not, the non-covered spouse’s Traditional IRA contributions may be fully deductible regardless of their combined income when filing jointly. If the working spouse is covered by a workplace retirement plan, contributions are fully deductible for joint filers with a household income below $230,000 for 2024.
