Filing a Joint Return

Both you and your spouse must include all of your income, exemptions, and deductions on your joint return.

Accounting period. Both of you must use the same accounting period, but you can use different accounting methods. See Accounting Periods and Accounting Methods in Chapter 1.

Joint responsibility. Both of you may be held responsible, jointly and individually, for the tax and any interest or penalty due on your joint return. This means that if one spouse does not pay the tax due, the other may have to. Or, if one spouse does not report the correct tax, both spouses may be responsible for any additional taxes assessed by the IRS. One spouse may be held responsible for all the tax due even if all the income was earned by the other spouse.

You may want to file separately if:

• You believe your spouse is not reporting all of his or her income, or
• You do not want to be responsible for any taxes due if your spouse does not have enough tax withheld or does not pay enough estimated tax.

Divorced taxpayer. You may be held jointly and individually responsible for any tax, interest, and penalties due on a joint return filed before your divorce. This responsibility may apply even if your divorce decree states that your former spouse will be responsible for any amounts due on previously filed joint returns.

Relief from joint responsibility. In some cases, one spouse may be relieved of joint responsibility for tax, interest, and penalties on a joint return for items of the other spouse that were incorrectly reported on the joint return. You can ask for relief no matter how small the liability.

There are three types of relief available.

1. Innocent spouse relief.
2. Separation of liability (available only to joint filers who are divorced, widowed, legally separated, or have not lived together for the 12 months ending on the date the election for this relief is filed).
3. Equitable relief.

You must file Form 8857, Request for Innocent Spouse Relief, to request relief from joint responsibility. Pub. 971, Innocent Spouse Relief, explains these kinds of relief and who may qualify for them.

Signing a joint return. For a return to be considered a joint return, both spouses generally must sign the return.

Spouse died before signing. If your spouse died before signing the return, the executor or administrator must sign the return for your spouse. If neither you nor anyone else has yet been appointed as executor or administrator, you can sign the return for your spouse and enter “Filing as surviving spouse” in the area where you sign the return.

Spouse away from home. If your spouse is away from home, you should prepare the return, sign it, and send it to your spouse to sign so that it can be filed on time.

Injury or disease prevents signing. If your spouse cannot sign because of disease or injury and tells you to sign for him or her, you can sign your spouse’s name in the proper space on the return followed by the words “By (your name), Husband (or Wife).” Be sure to also sign in the space provided for your signature. Attach a dated statement, signed by you, to the return. The statement should include the form number of the return you are filing, the tax year, the reason your spouse cannot sign, and should state that your spouse has agreed to your signing for him or her.

Signing as guardian of spouse. If you are the guardian of your spouse who is mentally incompetent, you can sign the return for your spouse as guardian.

Spouse in combat zone. You can sign a joint return for your spouse if your spouse cannot sign because he or she is serving in a combat zone (such as the Persian Gulf Area, Serbia, Montenegro, Albania, or Afghanistan), even if you do not have a power of attorney or other statement. Attach a signed statement to your return explaining that your spouse is serving in a combat zone. For more information on special tax rules for persons who are serving in a combat zone, or who are in missing status as a result of serving in a combat zone, see Pub. 3, Armed Forces’ Tax Guide.

Other reasons spouse cannot sign. If your spouse cannot sign the joint return for any other reason, you can sign for your spouse only if you are given a valid power of attorney (a legal document giving you permission to act for your spouse). Attach the power of attorney (or a copy of it) to your tax return. You can use Form 2848, Power of Attorney and Declaration of Representative.

Nonresident alien or dual-status alien. Generally, a married couple cannot file a joint return if either one is a nonresident alien at any time during the tax year. However, if one spouse was a nonresident alien or dual-status alien who was married to a U.S. citizen or resident alien at the end of the year, the spouses can choose to file a joint return. If you do file a joint return, you and your spouse are both treated as U.S. residents for the entire tax year. See chapter 1 of Pub. 519.

Special Rules

If you choose married filing separately as your filing status, the following special rules apply. Because of these special rules, you usually pay more tax on a separate return than if you use another filing status you qualify for.

1. Your tax rate generally is higher than on a joint return.
2. Your exemption amount for figuring the alternative minimum tax is half that allowed on a joint return.
3. You can’t take the credit for child and dependent care expenses in most cases, and the amount you can exclude from income under an employer’s dependent care assistance program is limited to $3,000 (instead of $6,000). However, if you are legally separated or living apart from your spouse, you may be able to file a separate return and still take the credit. For more information about these expenses, the credit, and the exclusion, see chapter 33.
4. You cannot take the earned income credit.
5. You cannot take the exclusion or credit for adoption expenses in most cases.
6. You cannot take the education credits (the American opportunity credit and lifetime learning credit) or the deduction for student loan interest or the tuition and fees deduction.
7. You cannot exclude any interest income from qualified U.S. savings bonds you used for higher education expenses.
8. If you lived with your spouse at any time during the tax year:
   1. You cannot claim the credit for the elderly or the disabled, and
   2. You must include in income a greater percentage (up to 85%) of any social security or equivalent railroad retirement benefits you received.
9. The following credits and deductions are reduced at income levels half those for a joint return:
   1. The child tax credit,
   2. The retirement savings contributions credit,
   3. The deduction for personal exemptions, and
   4. Itemized deductions.
10. Your capital loss deduction limit is $1,500 (instead of $3,000 on a joint return).
11. If your spouse itemizes deductions, you cannot claim the standard deduction. If you can claim the standard deduction, your basic standard deduction is half the amount allowed on a joint return.

Adjusted gross income (AGI) limits. If your AGI on a separate return is lower than it would have been on a joint return, you may be able to deduct a larger amount for certain deductions that are limited by AGI, such as medical expenses.

Individual retirement arrangements (IRAs). You may not be able to deduct all or part of your contributions to a traditional IRA if you or your spouse were covered by an employee retirement plan at work during the year. Your deduction is reduced or eliminated if your income is more than a certain amount. This amount is much lower for married individuals who file separately and lived together at any time during the year. For more information, see How Much Can You Deduct in Chapter 17.

Rental activity losses. If you actively participated in a passive rental real estate activity that produced a loss, you generally can deduct the loss from your nonpassive income, up to $25,000. This is called a special allowance. However, married persons filing separate returns who lived together at any time during the year cannot claim this special allowance. Married persons filing separate returns who lived apart at all times during the year are each allowed a $12,500 maximum special allowance for losses from passive real estate activities. See Limits on Rental Losses in Chapter 9.

Community property states. If you live in Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, or Wisconsin and file separately, your income may be considered separate income or community income for income tax purposes. See Pub. 555.

Considered Unmarried

To qualify for head of household status, you must be either unmarried or considered unmarried on the last day of the year. You are considered unmarried on the last day of the tax year if you meet all the following tests.

1. You file a separate return. A separate return includes a return claiming married filing separately, single, or head of household filing status.
2. You paid more than half the cost of keeping up your home for the tax year.
3. Your spouse didn’t live in your home during the last 6 months of the tax year. Your spouse is considered to live in your home even if he or she is temporarily absent due to special circumstances. See Temporary absences, under Qualifying Person, later.
4. Your home was the main home of your child, stepchild, or foster child for more than half the year. (See Home of qualifying person, under Qualifying Person, later, for rules applying to a child’s birth, death, or temporary absence during the year.)
5. You must be able to claim an exemption for the child. However, you meet this test if you cannot claim the exemption only because the noncustodial parent can claim the child using the rules described in Children of divorced or separated parents (or parents who live apart) under Qualifying Child in chapter 3, or referred to in Support Test for Children of Divorced or Separated Parents (or Parents Who Live Apart) under Qualifying Relative in chapter 3. The general rules for claiming an exemption for a dependent are explained under Exemptions for Dependents in chapter 3.

Nonresident alien spouse. You are considered unmarried for head of household purposes if your spouse was a nonresident alien at any time during the year and you do not choose to treat your nonresident spouse as a resident alien. However, your spouse is not a qualifying person for head of household purposes. You must have another qualifying person and meet the other tests to be eligible to file as a head of household.

Choice to treat spouse as resident. You are considered married if you choose to treat your spouse as a resident alien. See Pub. 519.

Keeping Up a Home

To qualify for head of household status, you must pay more than half of the cost of keeping up a home for the year. You can determine whether you paid more than half of the cost of keeping up a home by using Worksheet 2-1.

If the total amount you paid is more than the amount others paid, you meet the requirement of paying more than half the cost of keeping up the home.

Costs you include. Include in the cost of keeping up a home expenses such as rent, mortgage interest, real estate taxes, insurance on the home, repairs, utilities, and food eaten in the home.

If you used payments you received under Temporary Assistance for Needy Families (TANF) or other public assistance programs to pay part of the cost of keeping up your home, you cannot count them as money you paid. However, you must include them in the total cost of keeping up your home to figure if you paid over half the cost.

Costs you do not include. Do not include the costs of clothing, education, medical treatment, vacations, life insurance, or transportation. Also, do not include the rental value of a home you own or the value of your services or those of a member of your household.

Qualifying Person

See Table 2.1 to see who is a qualifying person. Any person not described in Table 2.1 is not a qualifying person.

Example 1—child. Your unmarried son lived with you all year and was 18 years old at the end of the year. He did not provide more than half of his own support and does not meet the tests to be a qualifying child of anyone else. As a result, he is your qualifying child (see Qualifying Child in chapter 3) and, because he is single, your qualifying person for you to claim head of household filing status.

Example 2—child who is not qualifying person. The facts are the same as in] Example 1 except your son was 25 years old at the end of the year and his gross income was $5,000. Because he does not meet the age test (explained under Qualifying Child in chapter 3), your son is not your qualifying child. Because he does not meet the gross income test (explained later under Qualifying Relative in chapter 3), he is not your qualifying relative. As a result, he is not your qualifying person for head of household purposes.

Example 3—girlfriend. Your girlfriend lived with you all year. Even though she may be your qualifying relative if the gross income and support tests (explained in chapter 3) are met, she is not your qualifying person for head of household purposes because she is not related to you in one of the ways listed under Relatives who do not have to live with you in chapter 3. See Table 2-1.

Example 4—girlfriend’s child. The facts are the same as in Example 3 except your girlfriend’s 10-year-old son also lived with you all year. He is not your qualifying child and, because he is your girlfriend’s qualifying child, he is not your qualifying relative (see Not a Qualifying Child Test in chapter 3). As a result, he is not your qualifying person for head of household purposes.

Home of qualifying person. Generally, the qualifying person must live with you for more than half of the year.

Special rule for parent. If your qualifying person is your father or mother, you may be eligible to file as head of household even if your father or mother does not live with you. However, you must be able to claim an exemption for your father or mother. Also, you must pay more than half the cost of keeping up a home that was the main home for the entire year for your father or mother.

If you pay more than half the cost of keeping your parent in a rest home or home for the elderly, that counts as paying more than half the cost of keeping up your parent’s main home.

Death or birth. You may be eligible to file as head of household even if the individual who qualifies you for this filing status is born or dies during the year. If the individual is your qualifying child, the child must have lived with you for more than half the part of the year he or she was alive. If the individual is anyone else, see Pub. 501.

Temporary absences. You and your qualifying person are considered to live together even if one or both of you are temporarily absent from your home due to special circumstances such as illness, education, business, vacation, military service, or detention in a juvenile facility. It must be reasonable to assume the absent person will return to the home after the temporary absence. You must continue to keep up the home during the absence.

Qualifying Widow(er) With Dependent Child

If your spouse died in 2017, you can use married filing jointly as your filing status for 2017 if you otherwise qualify to use that status. The year of death is the last year for which you can file jointly with your deceased spouse. See Married Filing Jointly, earlier.

You may be eligible to use qualifying widow(er) with dependent child as your filing status for 2 years following the year your spouse died. For example, if your spouse died in 2016, and you have not remarried, you may be able to use this filing status for 2017 and 2018.

This filing status entitles you to use joint return tax rates and the highest standard deduction amount (if you do not itemize deductions). It does not entitle you to file a joint return.

How to file. If you file as qualifying widow(er) with dependent child, you can use Form 1040. If you also have taxable income of less than $100,000 and meet certain other conditions, you may be able to file Form 1040A. Check the box on line 5 of either form. Use the Married filing jointly column of the Tax Table or Section B of the Tax Computation Worksheet to figure your tax.

Eligibility rules. You are eligible to file your 2017 return as a qualifying widow(er) with dependent child if you meet all of the following tests.

• You were entitled to file a joint return with your spouse for the year your spouse died. It does not matter whether you actually filed a joint return.
• Your spouse died in 2015 or 2016 and you did not remarry before the end of 2017.
• You have a child or stepchild for whom you can claim an exemption. This does not include a foster child.
• This child lived in your home all year, except for temporary absences. See Temporary absences, earlier, under Head of Household. There are also exceptions, described later, for a child who was born or died during the year and for a kidnapped child.
• You paid more than half the cost of keeping up a home for the year. See Keeping Up a Home, earlier, under Head of Household.

Example. John’s wife died in 2015. John has not remarried. During 2016 and 2017, he continued to keep up a home for himself and his child, who lives with him and for whom he can claim an exemption. For 2015 he was entitled to file a joint return for himself and his deceased wife. For 2016 and 2017, he can file as qualifying widower with a dependent child. After 2017 he can file as head of household if he qualifies.

Death or birth. You may be eligible to file as a qualifying widow(er) with dependent child if the child who qualifies you for this filing status is born or dies during the year. You must have provided more than half of the cost of keeping up a home that was the child’s main home during the entire part of the year he or she was alive.

Kidnapped child. You may be eligible to file as a qualifying widow(er) with dependent child even if the child who qualifies you for this filing status has been kidnapped. See Pub. 501.
