A taxpayer’s filing status plays a crucial role in determining the tax rate at which tax will be calculated and the amount of standard deduction that will be applied to calculating taxable income.
Therefore, it is very important to correctly indicate your filing status before submitting your return, as choosing the wrong filing status can lead to an audit or result in overpaying taxes.
How to Determine Filing Status
A taxpayer’s filing status depends on their marital status and whether they have dependents. The IRS provides five statuses, from which you must choose one that best fits when completing your tax return:
-
Single
-
Married Filing Jointly
-
Married Filing Separately
-
Head of Household
-
Qualifying Widow(er) (Surviving Spouse)

Detailed Guide to Each Filing Status
Determining Marital Status
A taxpayer’s marital status is determined as of December 31 of the tax year.
1. Single
The Single filing status applies to taxpayers who are not married or are legally divorced as of December 31. Additionally, choosing this status assumes that the person filing the return has no other family members as dependents.
2. Married Filing Jointly (MFJ)
The Married Filing Jointly status can be chosen by married couples, including same-sex couples. This status involves filing a joint return that shows the couple’s combined income and expenses for the reporting year.
Pros & Cons:
-
Pro: MFJ status provides somewhat more tax benefits than filing separate married returns.
-
Con: You and your spouse bear “joint and several liability,” meaning each of you is personally responsible for the accuracy of the return and paying taxes owed. The IRS can collect the full amount from you personally, even if you earned only 10% of the income.
3. Married Filing Separately (MFS)
This status involves spouses filing separate tax returns. Individuals who choose Married Filing Separately (MFS) cannot claim certain tax benefits and credits, including the Earned Income Credit and American Opportunity Credit.
Reasons why spouses might file separately:
-
One spouse wants to file a tax return, and the other has no desire to do so.
-
One spouse suspects that the joint return may be inaccurate.
-
One spouse does not wish to be responsible for paying the full tax shown on the joint return.
-
One spouse owes taxes and the other is due a refund.
-
Husband and wife have separated but are not yet legally divorced, and they want their finances to be separate.
Note: Even when choosing MFS, spouses will have to coordinate tax information if they have minor children to determine who will claim them as dependents.
4. Head of Household (HOH)
Individuals who are not married as of December 31 are entitled to this status if they have dependent(s) under their care.
Requirements:
-
You were not married as of December 31 (or considered unmarried and lived apart from your spouse for the last 6 months).
-
You paid more than half the cost of maintaining your household during the tax year.
-
You cared for a qualifying person (e.g., child) who lived with you for more than half the year.
5. Qualifying Widow(er) With Dependent Child
If one spouse died during the tax year, the widow(er) may file a joint return for that period.
From the following year, the widow(er) may be able to file as Qualifying Widow(er) for two more years. This status allows you to use the MFJ tax rates and standard deduction.
Requirements:
-
You cannot remarry during the two years.
-
You must have a dependent child who lived with you throughout the entire tax year.
Can You Change Status After Filing?
Married couples must decide whether they want to file their tax return for the year jointly or separately.
-
Separate to Joint: You can switch from two separate returns to a single joint return within three years from the date of filing the first return.
-
Joint to Separate: Switching from a joint return to two separate ones is only possible until the end of the tax deadline for that tax year.
Conclusion
Determining filing status is an important stage of completing tax reporting. An error when choosing filing status can lead to unpleasant consequences.
