First comes love, then comes marriage… then comes figuring out how to file your taxes together.
If you recently tied the knot, congratulations! Whether you eloped on a beach or walked down a candlelit aisle, marriage brings plenty of changes, and your taxes are one of them. Here are some practical, IRS-backed tips to help you and your spouse start your married life off on the right (tax) foot.
1. Choose your filing status wisely
After you’re married, your tax filing status is either married filing jointly or married filing separately. You can’t file single anymore. Most couples benefit from filing jointly. In fact, the tax code is set up to encourage it.
To reduce the so-called marriage penalty, Congress structured six of the seven federal tax brackets so that joint filers receive exactly double the threshold amounts of single filers. That means many couples see no increase in tax simply because they got married. Better yet, some couples may even enjoy what’s known as the marriage bonus, especially when one spouse earns significantly more than the other. Combining incomes could pull some of the higher earner’s income into a lower bracket.
The only bracket where this doubling doesn’t apply is the top 37% rate. For tax year 2025, that bracket kicks in at $751,600 for joint filers.
What about married filing separately? It’s not typically beneficial from a tax standpoint. In most cases, you’ll pay more in taxes, and you’ll lose eligibility for various deductions and credits, like the student loan interest deduction and most education credits. However, filing separately may be helpful in specific cases, like when one spouse has significant medical expenses, but for most, it’s worth running the numbers both ways before deciding.
2. Update the IRS and Social Security Administration
If either of you changed your name after marriage, make sure the Social Security Administration (SSA) knows about it. The name on your tax return must match what’s on file with the SSA. If it doesn’t, your e-filed return could be rejected, or your refund could be delayed.
Also, update your address with the IRS and U.S. Postal Service, if applicable. Use Form 8822, Change of Address, to report address changes to the IRS, and make sure your employer has your new address, so your Form W-2 ends up in the right place.
3. Rethink your withholding
Now that you’re married, your combined income may push you into a different tax bracket – or reduce your overall tax liability, depending on your situation. Either way, checking your federal income tax withholding is a good idea.
Use the IRS Tax Withholding Estimator to help decide whether to update your Form W-4, Employee’s Withholding Certificate, with your employer. Both you and your spouse should do this to avoid unpleasant surprises at tax time or accidentally withholding too much.
4. Coordinate tax benefits
Some tax breaks have income limits, like Roth IRA contributions, child tax credits or education credits. These phase out when your joint income hits certain thresholds. Your new household income could affect your eligibility for certain deductions or credits you previously qualified for as a single filer.
Also, remember that there are rules about claiming dependents, especially if one of you has children from a prior relationship. Understanding who qualifies as a dependent is crucial for filing accurately and avoiding delays.
5. Selling a home? You could double your tax-free gain
If you sold a home recently or plan to, you may qualify for a much larger tax break now that you’re married. The home sale exclusion allows up to $500,000 of tax-free profit on the sale of a primary residence for married couples filing jointly (compared to $250,000 for single filers).
To qualify, at least one spouse must have owned the home for at least two of the last five years, and both spouses must have lived in it for at least two of the last five years.
Other smart tax and financial moves for newlyweds
Marriage is about more than just shared finances. Here are a few other areas where combining your lives could require an update:
Update beneficiaries
Make sure to update the beneficiary designations on your retirement accounts, life insurance, and investment accounts. These designations override your will, so it’s important they reflect your new marital status.
Review health insurance options
Marriage is a qualifying life event that allows you to join your spouse’s employer-sponsored health plan or shop for coverage on the marketplace. Compare costs, deductibles, and coverage to choose what’s best for both of you.
Rethink your IRA and Roth strategy
Your joint income could affect your eligibility for Roth IRA contributions. If you’re above the phaseout limits, consider spousal IRAs or explore backdoor Roth strategies with a tax professional’s help.
Notify the Marketplace to avoid premium tax credit surprises
If either of you receives health insurance through the Marketplace, be sure to report your marriage and household income changes right away.
Your premium tax credit (PTC) is based on your projected household income and family size, so going from single to married can significantly affect your subsidy. If you don’t update your account, you may:
- Receive too much credit and owe some back when you file
- Lose eligibility altogether and be underinsured, or
- Miss out on additional savings you are now eligible for
To avoid surprise tax bills or coverage gaps, log into your Marketplace account and update your application as soon as your marital status or income changes.
Understand community property rules
If you live in a community property state, you may need to split income and deductions equally between spouses, regardless of who earned or paid what. Check the rules in your state and consult a professional if needed.
Pay attention to estimated taxes
If you’re self-employed or one of you has side income, your combined earnings could increase your quarterly estimated tax requirements. Don’t wait until next April, adjust your withholding as needed to avoid penalties.
Update or create an estate plan
Marriage changes everything to include wills, powers of attorney and your health care directives. Talk to an estate planning attorney about updating your documents, especially if either of you has children from a previous relationship.
Review your student loans
Getting married can affect student loan repayment, especially if you’re on an income-driven repayment plan. Your spouse’s income may now be factored into your monthly payment, and filing status (joint or separate) can impact how much you owe.
Final thoughts
Marriage changes more than your last name and filing status. Marriage changes your financial future. By updating your records, reviewing your withholding, and planning around new financial realities, you’ll set yourselves up for a smooth transition into married life.
Taxes might not be romantic, but thoughtful planning today means fewer headaches tomorrow and more time to enjoy your honeymoon phase.
