The wedding is over. You've unpacked the gifts, settled into your new routine, and then—tax season arrives. For many newlyweds, it's the first time they realize just how much getting married affects their finances on paper.
The good news: your first tax season as a married couple is very manageable once you know what to expect. And if you want one place to store your tax documents, track financial updates, and stay organized year-round, The Vow Vault was built for exactly that.
Your Marital Status on December 31 Is What Counts
The IRS determines your filing status based on your marital status on the last day of the tax year. If you were married any time before December 31, you're considered married for that entire tax year—even if the wedding was on December 30.
Make Sure Your Name Matches
If you changed your last name after the wedding, your name on your tax return must match what's on file with the Social Security Administration. If there's a mismatch, your return could be delayed. Update your SSA record before you file.
Update Your W-4 With Your Employer
Getting married changes your tax situation, which means your withholding may need to change too. Submit a new W-4 to your employer to reflect your updated filing status. The IRS withholding estimator can help you figure out the right amount.
Filing Jointly vs. Separately: What to Know
Most married couples benefit from filing jointly—it typically results in a lower tax rate and access to more credits and deductions. However, filing separately can make sense in certain situations, such as when one spouse has significant medical expenses or income-based student loan repayments.
If you're unsure, a tax professional can run the numbers both ways to see which option saves you more.
Watch for the "Marriage Penalty" or "Marriage Bonus"
Depending on your combined income, you may owe slightly more or less in taxes than you did as individuals. This is a normal result of how tax brackets work for married filers and isn't something to worry about—just something to be aware of when planning.
Gather Your Documents Early
Tax season is much smoother when your documents are already organized. You'll typically need:
- W-2s from all employers
- 1099s for any freelance or investment income
- Records of deductible expenses
- Last year's tax return (for reference)
- Social Security numbers for both spouses
Start Your Marriage With Good Financial Habits
Tax season is a great reminder of why staying organized year-round matters. When your documents are in one place and your financial records are easy to find, filing becomes a task instead of a project.
