Tax Benefits of Marriage: How Tying the Knot Can Lower Your Tax Bill

The Tax Advantages of Marriage

Marriage is often viewed as a romantic and personal milestone, but it also comes with financial implications—especially when it comes to taxes. For American couples, saying “I do” can unlock several tax benefits that may reduce their overall tax liability. From the possibility of a lower tax bracket to enhanced deductions, filing jointly as a married couple can offer significant advantages. However, there are also cases where marriage may result in a higher tax bill, often referred to as the “marriage penalty.” In this article, we’ll explore the various tax benefits of marriage, how they can impact your financial situation, and what you need to know when filing your taxes (as a lovingly married couple!) in 2025.

Filing Status Options After Marriage

You know how there’s plenty of filing statuses to choose from? Once you get married, you have two filing status options: married filing jointly (MFJ) or married filing separately (MFS). For most couples, filing jointly is the better choice, as it typically offers more generous tax benefits. When you file jointly, you and your spouse combine your incomes, deductions, and credits into a single tax return. This often leads to lower tax rates and eligibility for valuable credits.

Filing separately is less common but may be advantageous in specific situations, such as when one spouse has substantial medical expenses or if you want to keep tax liabilities separate due to personal or legal reasons. However, separate filing can disqualify you from many credits and deductions, which makes it a less appealing option for most married couples.

Lower Tax Rates and Larger Standard Deduction

One of the most immediate tax benefits of marriage is the potential for lower tax rates. When you file jointly, the tax brackets for married couples are generally more favorable than those for single filers. This can reduce your overall tax liability, particularly if you and your spouse have significantly different income levels.

For example, in 2025, the standard deduction for married couples filing jointly is $29,200, which is double the $14,600 standard deduction for single filers. This higher deduction reduces the amount of income subject to taxation, lowering your overall tax bill.

Access to Valuable Tax Credits

Married couples filing jointly often have access to tax credits that single filers or those filing separately may not qualify for. Some of the most significant tax credits include:

• Child Tax Credit: If you have children, filing jointly allows you to claim the child tax credit, which reduces your tax bill by up to $2,000 per qualifying child.
• Earned Income Tax Credit (EITC): This credit is designed to benefit low- to moderate-income earners. When filing jointly, you may qualify for a larger EITC compared to filing separately.
• Education Credits: If you or your spouse is pursuing higher education, you may qualify for education-related credits, such as the American Opportunity Credit or the Lifetime Learning Credit. Filing jointly can increase the income threshold for these credits, making you more likely to qualify.

Tax-Free Transfer of Assets and Gifts

One significant tax benefit of marriage is the ability to transfer unlimited assets and gifts between spouses without triggering gift taxes. This is known as the unlimited marital deduction, and it can be a powerful tool for both tax planning and wealth preservation.

Under this rule, married couples can transfer property, cash, or other valuable assets to each other without facing federal gift tax consequences. This benefit applies regardless of the value of the transferred assets. For example, if one spouse owns a home, they can transfer full or partial ownership to their partner without it being considered a taxable gift. Similarly, you can gift large sums of money, stocks, or valuable personal property to your spouse without any tax implications.

The unlimited marital deduction is particularly useful for estate planning purposes. When one spouse passes away, the surviving spouse can inherit the deceased partner’s entire estate tax-free. This allows couples to delay estate tax liability until the death of the second spouse. By doing so, families can preserve more wealth and potentially reduce or avoid estate taxes altogether.

It is important to note that the unlimited marital deduction only applies to transfers between U.S. citizens. If one spouse is a non-U.S. citizen, the deduction is limited. In 2025, the annual tax-free gift limit to a non-citizen spouse is $185,000. While this is still a sizable exclusion, it is not unlimited.

Additionally, while the unlimited marital deduction helps with tax-free transfers between spouses, it does not shield assets from estate taxes entirely. After the death of the second spouse, the estate may still be subject to federal estate taxes. However, married couples can take advantage of “portability,” which allows the surviving spouse to inherit the unused portion of the deceased spouse’s estate tax exemption.ially shield around $27.22 million from federal estate taxes by using portability.

Overall, the unlimited marital deduction is a valuable tax benefit that allows married couples to transfer wealth freely between each other without immediate tax consequences. It also plays a key role in estate planning strategies, helping couples maximize the amount of wealth they can preserve for their heirs.

Increased IRA Contribution Limits

Being married can also offer advantages when it comes to retirement savings. If only one spouse has earned income, the couple can still contribute to two Individual Retirement Accounts (IRAs) by utilizing the spousal IRA contribution rules. This allows the non-working spouse to make tax-advantaged contributions, effectively doubling the couple’s retirement savings potential.

Additionally, filing jointly may allow you to qualify for a larger deduction for traditional IRA contributions. Since the income phase-out thresholds for Roth IRA contributions are higher for married couples filing jointly, you may be able to contribute to a Roth IRA even with a higher combined income.

Estate Tax Benefits for Married Couples

Marriage provides couples with significant estate tax benefits. When one spouse passes away, the unlimited marital deduction allows the surviving spouse to inherit the deceased spouse’s estate tax-free. This deferral of estate taxes can be a powerful tool in estate planning, helping couples preserve wealth for their heirs.

Additionally, married couples have the option to combine their estate tax exemption amounts. In 2025, the federal estate tax exemption is projected to be approximately $13.61 million per person, meaning a married couple can protect up to $27.22 million from estate taxes.

The Potential for the Marriage Penalty

While there are many tax benefits to marriage, it’s worth noting that some couples may experience the so-called marriage penalty. This occurs when combining two incomes pushes the couple into a higher tax bracket, resulting in a larger tax bill than if they filed separately. The marriage penalty is more likely to affect couples with similar incomes.

For example, if two high-earning individuals marry, their combined income may push them into a higher tax bracket, reducing the benefits of filing jointly. This is less of an issue for couples with significantly different income levels, who are more likely to benefit from the marriage bonus.

Tax Planning Tips for Married Couples

To make the most of the tax benefits of marriage, it’s helpful to engage in strategic tax planning. Here are some tips to consider:

• Adjust Your Withholding: Once married, review your W-4 withholdings to avoid overpaying or underpaying taxes.
• Maximize Retirement Contributions: Take advantage of the higher income thresholds for Roth IRA contributions and spousal IRA rules.
• Coordinate Deductions: When filing jointly, you can combine deductions, such as mortgage interest and charitable contributions, which may result in a larger tax benefit.
• Consider Filing Separately in Specific Cases: While filing jointly is typically better, there may be rare cases where filing separately is advantageous, such as when one spouse has substantial medical expenses.

The Final Word on the Tax Benefits of Marriage…

Marriage can provide numerous tax benefits, from lower tax rates and larger deductions to access to valuable credits and estate tax advantages. However, the benefits vary depending on your financial situation. While most couples enjoy a marriage bonus, some may face a marriage penalty.

To fully take advantage of the tax benefits of marriage (and you really do, trust us), it’s important to review your tax situation each year and consider consulting with a tax professional. With proper planning, marriage can not only be a meaningful personal commitment but also a financially rewarding one.

Tax Advantages of Marriage: FAQ

1. How does getting married affect my tax filing status?
When you get married, you have two filing status options: married filing jointly or married filing separately. Filing jointly combines both spouses’ income, deductions, and credits, which often results in a lower overall tax liability. On the other hand, filing separately can be beneficial in certain situations, such as when one spouse has high medical expenses or if you want to keep your tax responsibilities separate. However, filing separately can disqualify you from many credits, making it less advantageous in most cases.

2. What is the “marriage bonus” and how does it work?
The marriage bonus is a tax benefit that occurs when a couple’s combined income is taxed at a lower rate than if they had filed separately. This is because the lower-earning spouse’s portion helps reduce the couple’s combined taxable income, potentially pushing them into a lower tax bracket. The marriage bonus results in a smaller tax bill and can also make it easier to qualify for credits with higher income thresholds.

3. Are there any tax penalties for married couples?
Yes, some married couples experience what is known as the “marriage penalty.” This happens when two individuals with similar incomes get married and their combined earnings push them into a higher tax bracket. As a result, they may pay more in taxes than they would have as two single filers. The marriage penalty is more common among higher-income couples or when both spouses have similar and relatively high earnings.

4. What tax credits do married couples qualify for?
Married couples who file jointly have access to several valuable tax credits. The Child Tax Credit is one of the most significant, providing up to $2,000 per qualifying child. The Earned Income Tax Credit (EITC) is another important credit, especially for low- to moderate-income households. Married couples often qualify for a larger EITC due to the higher income thresholds for joint filers. Additionally, couples may benefit from education-related credits, such as the American Opportunity Credit or the Lifetime Learning Credit, which help offset the cost of higher education expenses. Joint filers also have a higher income threshold for these credits, making it easier to qualify.

5. How does marriage affect retirement contributions and deductions?
Marriage can positively impact your ability to contribute to retirement accounts. When filing jointly, couples benefit from higher income thresholds for Roth IRA contributions, allowing them to continue contributing even with a higher combined income. Additionally, if one spouse does not have earned income, the working spouse can make contributions to a spousal IRA on their behalf. This effectively allows the couple to double their IRA contributions, helping them maximize their retirement savings. Joint filers may also qualify for a larger deduction on traditional IRA contributions, depending on their combined income and whether they are covered by a workplace retirement plan.
