Married Filing Jointly vs. Separately: Which Filing Status Is Right for You?

Marriage changes everything—including your taxes. When tax season rolls around, married couples have an important choice to make: Should you file jointly or separately? Your decision can impact how much tax you pay, the size of your refund, and your financial stability.

In this guide, we’ll explore the pros and cons of both filing statuses so you can make the best decision for your unique situation.

The Benefits of Filing Jointly

Filing jointly means you and your spouse submit a single tax return that combines your incomes, deductions, and credits. This filing status offers several advantages:

1. Higher Standard Deduction

Couples filing jointly enjoy the largest standard deduction. For example, in 2021, the standard deduction for joint filers was $25,100, significantly reducing taxable income.

2. Lower Tax Rates

Joint filers benefit from more favorable tax brackets. For instance, in 2021, the 10% tax bracket applied to the first $19,900 of taxable income for joint filers, compared to $9,950 for those filing separately.

3. Access to Key Tax Credits

Certain tax credits are only available to joint filers, such as:

• Earned Income Tax Credit (EITC): For low-to-moderate income households.
• Child and Dependent Care Credit: To offset childcare costs.
• Education Tax Credits: Including the American Opportunity and Lifetime Learning Credits.

4. Simplicity for Community Property States

If you live in a community property state (e.g., California, Texas, or Arizona), filing jointly can avoid the complexities and extra rules that come with separate filings.

When Filing Separately Might Be Better

While joint filing is usually more beneficial, there are certain situations where filing separately could save you money or protect your interests.

1. High Medical Expenses

You can deduct medical expenses that exceed 7.5% of your adjusted gross income (AGI). Filing separately lowers the AGI threshold, making it easier to qualify for this deduction. For example:

• Joint filers with a $90,000 AGI need over $6,750 in medical expenses to deduct.
• Separate filers with a $50,000 AGI only need $3,750.

2. Avoiding the Alternative Minimum Tax (AMT)

If one spouse’s income is subject to the AMT, filing separately may reduce your liability. For 2021, the AMT threshold for joint filers was $114,600, but it was only $57,300 for separate filers. Filing separately ensures only the higher-income spouse faces the AMT.

3. Protecting Yourself During Divorce

If you’re going through a divorce, filing separately can separate your tax liabilities. This prevents shared responsibility for taxes owed by your spouse.

4. Shielding Refunds from Student Loan Debt

If one spouse has defaulted on federal student loans, filing separately protects the other spouse’s tax refund from being seized to cover unpaid debt.

How to Decide: Jointly or Separately?

The best way to choose your filing status is to run the numbers both ways. Many tax software programs and professionals can help you compare scenarios to determine which option saves you the most money.

Here are some general guidelines:

• File jointly if you want access to more tax credits and deductions.
• File separately if one of you has high medical expenses, faces the AMT, or has other liabilities.

Conclusion: Choose the Option That Works for You

Filing jointly offers most married couples greater tax benefits, but it’s not always the best choice. By understanding your financial situation and running a side-by-side comparison, you can choose the filing status that minimizes your taxes and maximizes your refund.
