Yes, you may be able to claim your fiancé as a dependent on your federal income tax return, but only if your fiancé meets all the IRS requirements for a qualifying relative.
Being engaged does not itself create a qualifying family relationship for tax purposes. Your fiancé will normally have to live with you for the entire tax year, earn less than the applicable income limit and receive more than half of their total support from you.
Does Your Fiancé Have to Live With You?
Yes. Because a fiancé is not one of the relatives who can qualify while living elsewhere, your fiancé must generally live with you all year as a member of your household.
For example, to claim your fiancé on a 2025 return, your home generally must have been their home throughout 2025. A fiancé who moved into your home partway through the year will normally fail this requirement. Temporary absences for reasons such as illness, education, business, vacation or military service may still count as time lived with you.
The relationship must also not violate local law. The IRS gives the example of a significant other who cannot qualify when the living arrangement violates state law because that person is legally married to someone else.
How Much Income Can Your Fiancé Earn?
For a 2025 federal tax return, your fiancé’s gross income must be less than $5,200.
Gross income generally includes taxable income received in the form of money, property or services. It may include wages, taxable unemployment benefits, taxable Social Security benefits, rental income and business income.
The limit applies to gross income, not take-home pay. Therefore, a fiancé who earned exactly $5,200 or more in gross income during 2025 would generally fail the qualifying-relative income test.
This amount can change from year to year. The applicable limit for the specific tax year should be used.
How Does the Support Test Work?
You must provide more than half of your fiancé’s total support for the year.
Support generally includes expenses such as:
- Housing and utilities;
- Food;
- Clothing;
- Medical and dental costs;
- Transportation;
- Education;
- Recreation; and
- Other basic living expenses.
Free housing also counts as support. When your fiancé lives in a home that you own or rent, the fair rental value of their share of the accommodation may be included when calculating the support you provided.
Compare the total support you provided with support paid by your fiancé and other people. You must have paid more than 50% of the total.
For example, suppose your fiancé’s total support for the year was $18,000. You paid $11,000 and your fiancé paid $7,000. You satisfy the support test because you provided more than half.
What If Your Fiancé Has No Job?
A fiancé who has no income may qualify, but having no job does not automatically make the person your dependent.
Your fiancé must still have lived with you throughout the year, must not be another taxpayer’s qualifying child and must satisfy the citizenship, residency, joint-return and support requirements. The IRS requires all four basic qualifying-relative tests to be met.
What If Your Fiancé’s Parents Can Claim Them?
You generally cannot claim your fiancé as a qualifying relative when they are the qualifying child of their parents or another taxpayer.
This issue may arise when the fiancé is under age 24, attends college full-time and meets the residency and support requirements to be claimed by a parent. The IRS qualifying-relative rules require that the person not be the qualifying child of any taxpayer.
The result depends on whether the fiancé actually meets the qualifying-child tests, not merely whether their parents decide to claim them.
What If You Get Married During the Year?
You cannot claim the person as your dependent if they were your spouse at any time during the tax year.
If you marry your fiancé before the end of the year, they are treated as your spouse rather than as your qualifying relative. Married couples normally use married filing jointly or married filing separately. A joint return may be filed even when one spouse has no income.
For example, if you lived together throughout 2025 but married on December 31, 2025, you would not claim your partner as a dependent for 2025. You would generally file using a married filing status.
Does Your Fiancé Need a Social Security Number?
A dependent must generally have a valid taxpayer identification number. This may be a Social Security number or, when permitted, an Individual Taxpayer Identification Number.
For the 2025 Credit for Other Dependents, the dependent must have an eligible taxpayer identification number issued by the return’s due date, including extensions. The person must also satisfy the applicable citizenship or residency requirements.
What Tax Benefit Can You Receive?
An eligible fiancé claimed as a qualifying relative may allow you to claim the Credit for Other Dependents, subject to the credit’s identification, residency, income and tax-liability rules.
This is a nonrefundable credit, meaning it may reduce the federal income tax you owe but cannot by itself create a refund beyond your tax liability. The credit may also be reduced at higher income levels.
However, claiming an unrelated fiancé as a dependent generally does not make you eligible to file as head of household. A person who qualifies only because they lived with you all year is not normally a qualifying person for head-of-household status.
The Bottom Line
You may claim your fiancé as a dependent when all the qualifying-relative requirements are satisfied. For a 2025 return, your fiancé generally must:
- Have lived with you throughout the year;
- Have gross income below $5,200;
- Have received more than half of their support from you;
- Not be another taxpayer’s qualifying child;
- Meet the citizenship or residency rules; and
- Not have been your spouse at any time during the year.
Engagement alone is not enough. The claim depends on your living arrangement, your fiancé’s income, the support you provided and whether another taxpayer is entitled to claim them.
