No formal notification is required, but your tax filing status automatically changes based on your marital status as of December 31, 2025. If you’re legally married by year-end, you must file as either Married Filing Jointly (MFJ) or Married Filing Separately (MFS) for that entire tax year.
The IRS will match your names and Social Security numbers against their records. If either of you changed your name after marriage, make sure to update it with the Social Security Administration first. This avoids delays in tax processing or issues with your refund.
Client Example: Mark and Elena married on December 28, 2025. Though they were single for most of the year, they qualified to file jointly and saved over $3,000 in federal taxes thanks to Elena’s higher income and the joint brackets.
In most cases, filing Married Filing Jointly (MFJ) results in a lower combined tax bill. For 2025, MFJ couples receive a $29,200 standard deduction, nearly double the $14,600 for single filers. Joint filers also benefit from wider tax brackets, better access to education credits, and more favorable phase-outs for deductions.
However, you may benefit from filing separately if:
CPA Insight: One mistake I see all the time is couples assuming joint is always better. Sometimes filing separately helps preserve a lower student loan payment or isolate tax risk.
Client Example: James and Sophia filed separately because James had $120K in student loans on an IDR plan. Their separate returns kept his monthly payment at $380, instead of $1,150 — saving over $9,000 annually.
Yes — and don’t delay. Once you’re married, your tax bracket, standard deduction, and household income all change. If you keep your old W-4 settings, you risk under-withholding or over-withholding, which could lead to a surprise tax bill or smaller paycheck.
Use the IRS Tax Withholding Estimator to update both of your W-4s based on:
CPA Insight: I recommend updating your W-4s within 30 days of getting married, then reviewing them again early in the new year to make sure they’re aligned.
Generally, wedding expenses are not tax-deductible. This includes venue costs, food, dresses, rings, and most other wedding-related expenses. However, you may be able to deduct certain costs if the wedding was tied to business or professional purposes (e.g., for a business promotional event or a charitable wedding auction).
CPA Insight: While wedding expenses themselves are not deductible, certain gifts and contributions made at a wedding could be. For example, charitable donations made in lieu of gifts might be deductible as charitable contributions.
Opening a joint bank account is a common step for married couples to simplify finances. By combining income, it becomes easier to manage household expenses, savings goals, and investments. However, you can also maintain separate accounts, which allows for more financial independence.
Before opening a joint account, make sure both parties agree on budgeting and spending habits. Setting up automatic transfers for shared expenses, like mortgage payments or utilities, can streamline this process.
CPA Insight: Keep track of who is making the deposits and withdrawals from the joint account, as this could have implications for taxes, especially when it comes to credit and debt management.
Yes! Marriage often calls for a review and update of your health, life, auto, and homeowners’ insurance policies. Be sure to add your spouse to your existing policies and ensure you are both covered adequately.
For health insurance, check if you can join your spouse’s plan or if you need to update your own. Consider reviewing life insurance, as your beneficiaries might need to be updated to reflect your new marital status.
Client Example: Sarah and Joe saved $1,200 annually by combining their auto insurance into one plan and updating their health coverage through Sarah’s employer.
This depends on your financial habits. Some couples prefer to keep separate credit cards for maintaining financial independence or for managing personal spending. Others combine their cards for easier tracking of shared expenses.
Before making a decision, check the credit limits, interest rates, and rewards programs for each card. If you combine cards, you may benefit from higher credit limits and more flexible rewards programs, but it's essential to communicate about managing credit responsibly to avoid debt.
CPA Insight: If you keep separate accounts, ensure you have a shared system for tracking joint expenses. This will help when it comes time to file your taxes and potentially qualify for deductions based on joint costs.
It’s important to update your beneficiary designations on your retirement accounts after marriage. This includes 401(k)s, IRAs, and life insurance policies.
By default, many retirement accounts pass to a spouse, but it’s good practice to review and ensure your spouse is listed as the beneficiary. This can prevent issues if something happens unexpectedly, and you want to avoid probate court.
CPA Insight: Failure to update beneficiary designations can lead to complications. If a spouse is not listed as a primary beneficiary, assets could end up in the hands of a different person, which can delay the transfer process.
Refinancing your mortgage after marriage can potentially save you money, especially if you have a stronger joint credit score or a lower interest rate. If one of you has a higher credit score or income than the other, refinancing into a joint mortgage can help secure a better rate.
Additionally, refinancing could allow you to adjust your mortgage terms or access cash if you’ve accumulated home equity. However, make sure to weigh the costs of refinancing against potential savings to determine if it’s worth pursuing.
Client Example: After marrying, Jane and John refinanced their mortgage into both of their names, securing a lower interest rate, which saved them $400 per month in payments.
Student loan debt can be a significant concern for many couples. The way you handle this debt will vary depending on the type of loans (federal or private), whose name the loan is under, and your filing status.
If both spouses have student loans, consider consolidating or refinancing them. Federal loans may offer income-driven repayment plans that could lower monthly payments based on joint income. But refinancing federal loans with private lenders could eliminate these protections, so it’s important to carefully consider your options.
CPA Insight: Be cautious with student loan consolidation or refinancing. Depending on the type of loans you have, this could impact your eligibility for forgiveness programs or other government relief options.
Yes. Marriage significantly impacts your estate plan. After getting married, ensure your will, trust, and power of attorney documents reflect your new spouse as your beneficiary and decision-maker.
In many cases, marriage automatically grants a spouse inheritance rights, but updating your estate plan can prevent disputes and ensure your wishes are clearly stated. If you have children or other beneficiaries, this update is particularly important to ensure everyone’s rights are addressed.
Client Example: Tim and Rachel created a joint trust after getting married to ensure their assets would pass smoothly without probate, avoiding a lengthy and costly process.
Yes — preferably sooner than later. Marriage triggers cascading financial changes that ripple through taxes, payroll, investments, insurance, and estate planning.
A CPA can help you:
Client Example: A couple who met with me post-wedding saved $3,200 by adjusting their withholdings and using a spousal IRA strategy. They also caught an outdated beneficiary designation that could have created conflict down the road.
