Married Filing Jointly vs. Married Filing Separately
Married taxpayers have a choice when selecting their filing status. They can choose Married Filing Separately (MFS) or Married Filing Jointly (MFJ). One common question often comes up, “Which one is best for me?”
As with most tax related questions, the answers starts with, “It depends.” First is to be sure you are married.
For federal taxes, you are considered married if on the last day of the year you are married and living together. This includes common law marriages that are recognized in the state where you now live or in the state where the common law marriage began. Even if living apart, on the last day of the year you are considered married if there is no legal decree of divorce or separate maintenance.
The following sections expand upon some benefits and pitfalls of choosing MFS or MFJ. Sometimes the only way to determine the best way is to try both and compare the results. the last heading shows how to run a comparison of filing separately vs. jointly to see which is best for you.
Married Filing Separately limits deductions and credits
Married Filing Separately taxpayers may not eligible to claim the following tax benefits:
- Tuition and fees deduction
- Student loan interest deduction
- Tax-free exclusion of US bond interest
- Tax-free exclusion of Social Security Benefits
- Credit for the Elderly and Disabled
- Child and Dependent Care Credit
- Earned Income Credit
- Education Credits
Other drawbacks of Married Filing Separately:
- Taxpayers have a much lower income phase-out range for IRA deductions.
- Both spouses must claim the standard deduction, or both must itemize their deductions. One spouse cannot claim the standard deduction if the other is itemizing.
- This filing status generally pays the most tax of all the filing statuses.
When it may make sense to file separately
Since filing a joint return requires the consent of both spouses, it might sometimes make sense to not be included on your spouse’s tax return. Signing a joint tax return makes you both responsible for the accuracy and completeness of the return and obligates you for any current or future tax liability or penalties.
There are specific situations when it can be better to file separately. These include:
- When you need to separate your tax liability from your spouse. If you file separately, you will only be responsible for the accuracy and payment of taxes for your own return.
- In certain situations when there is a large disparity between incomes of the spouses. This may result in a combined lower tax situation, but usually only in separate (non-community) property states. See Married Filing Separately in a Community Property State section below.
If you are not sure, complete your taxes both ways to see which one may be best for you.
Married taxpayers and Head of Household filing status
You and your spouse did not live together during the last six months of the year and you maintained a home for your child for more than half the year. In certain situations you can be considered unmarried for tax filing purposes.
This filing status can allow you to claim the earned income credit along with other credits. Additionally, your standard deduction will be higher than if you file as Married Filing Separately. For more information, see Do I Qualify for Head of Household?
Married Filing Separately in a Community Property state
When one or both spouse live in a community property state special rules apply for allocating income and deductions between each spouse’s tax return. Community property states are: Arizona, California, Idaho, Louisiana, New Mexico, Nevada, Texas, Washington, and Wisconsin.
Each spouse generally reports one-half of the total income on each tax return.
The same goes for deductions – each spouse generally gets half of the deductions. This is often not exact, as for couples with an odd number of children.
What if I change my mind?
Married Filing Separately taxpayers can amend their returns and change to Married Filing Jointly within three years of the original due date of the return.
However, Married Filing Jointly have only until the April 15th deadline to change their minds and switch to Married Filing Separately.
What if my spouse died during the year?
If your spouse died during the year, you are considered married for the whole year for tax filing purposes. File Married Filing Jointly for most situations.
What about annulled marriages?
If you obtain a court decree of annulment which holds that no valid marriage ever existed, you are considered unmarried even if you filed a joint tax return in an earlier year.
You must file amended returns for any previous years which you filed as Married Filing Jointly for all tax years affected by the annulment that are not closed by the statute of limitations (generally 3 years). The amended returns should use either single, or if you qualify, Head of Household status.
How to compare filing separately vs. filing jointly
Using TurboTax Online —
- Prepare a joint federal and state return but don't file.
- Then prepare two Married Filing Separately returns (but don't file! - now you should have 3 returns, keep track of the logins!), and
- Compare the results betweeen the Marrried Filing Jointly and the two Married Filing Separately returns.
- Then complete and file the tax return(s) for the status you prefer or that provides the better result.
You don't have to pay for the tax return(s) you don't file. However you have to enter everything several times; be sure you remember to enter everything in each of the 3 returns! Yes this may be awkward but it could save you money!

However, there are reasons that you might want to file Married Filing Separately, even though it does not result in the lowest tax.
For example, you might choose to file separately if you want to be responsible for only your tax return, or if you and your spouse do not agree to file a joint return.
