For their 2025 federal income tax returns, married couples can choose to file either jointly or separately. This decision greatly affects your standard deduction amount, access to key tax benefits, applicable tax brackets, and your final tax liability. The best choice depends on your individual financial circumstances.
Which Filing Status Minimizes Tax?
Couples usually benefit from selecting the tax filing status that lowers their total tax bill, and this is most often filing jointly.
Joint filing can lead to significant tax advantages, especially when one spouse earns much more than the other. By combining incomes, some of the higher-earning spouse's income may be taxed at lower rates, which reduces the overall tax owed.
Tax Benefits Available Only to Joint Filers
Some valuable tax breaks are unavailable to married taxpayers who file separately, like:
Additionally, certain new deductions introduced under 2025’s One Big Beautiful Bill Act (OBBBA) are not available to separate filers, including:
Individuals who file separately may encounter restrictions, or even a total loss, of:
Deductions for IRA contributions, particularly if one spouse participates in an employer retirement plan like a 401(k)
The ability to exclude employer-provided adoption assistance from income
Exclusion of interest earned from Series EE or Series I savings bonds when used for higher education expenses
When Filing Separately Makes Sense
While joint filing is generally advantageous, certain scenarios may result in greater tax savings when spouses file separately. For instance, medical expenses are deductible only if they exceed 7.5% of adjusted gross income (AGI). In cases where one spouse incurs substantial medical costs, separate filing may enable that individual to claim a higher deduction due to a lower AGI. It is essential to perform thorough calculations for each situation.
If You Got Married in 2025
If you were married at any time during 2025, the IRS treats you as married for the entire year. This means you must file your taxes either jointly with your spouse or separately.
Although the lower and middle tax brackets and standard deductions are usually similar for both single filers and those married filing separately, some income thresholds are less advantageous for people who file separately. For instance, the highest tax rate of 37% starts at a much lower income for married individuals filing separately than for single filers. This also applies to:
The top long-term capital gains rate of 20%
The 3.8% Net Investment Income Tax
The 0.9% Additional Medicare Tax
Separate filers may also face greater exposure to the Alternative Minimum Tax (AMT).
Liability Matters: Joint and Several Responsibility
A key point to keep in mind when filing jointly is joint and several liability. By submitting a joint return, both you and your spouse become legally responsible for:
Paying all the taxes owed
Covering any extra tax that might be added later
Handling interest charges and most penalties
And the IRS can pursue either spouse for the entire balance.
While “innocent spouse” relief is available, it is not granted automatically and has limitations. Because of this, some couples especially those who are separated or having marital issues might opt to file separately, accepting higher taxes to avoid being responsible for their spouse’s tax debts.
Bottom Line
Deciding whether to file taxes as married filing jointly or separately can be complex. Factors such as income, deductions, credits, liability concerns, and long-term financial objectives all play a role in this choice. Comparing both options side by side is often the best way to figure out which suits your needs. If you're uncertain about the right filing status for 2025, we can assist you.
