You and your wife can file a joint federal income tax return even if she doesn’t work. Although each couple’s tax situation is different, you can generally claim more deductions and credits by filing a joint return. In most cases, your tax liability will be lower. Although your wife must file a tax return if she has unearned income that exceeds the limit the IRS allows, filing a joint rather than separate return can be advantageous to you both.
All married couples can file married filing jointly regardless if one spouse works and another doesn't.
What Is Taxable Income?
Even if your wife doesn’t work, she might still have taxable income. The gross income you calculate to arrive at the taxable income you report on your tax return includes both earned and unearned income. Earned income is the salary, wages, commissions and tips that a taxpayer earns. It also includes bonuses, sick pay and unemployment benefits. Any unearned income you or your wife receives is also added to your gross income. Unearned income includes business income, interest you earn on savings, income from investments, alimony payments, rents, royalties, distributions from retirement accounts and profits from assets you sell.
Married Filing Jointly Rules
Both you and your spouse must agree to file a joint return. One spouse can't file as married filing jointly and the other as married filing separately. Because you and your spouse must sign a joint return, you are both responsible for any tax liability or penalties you owe. On the other hand, if your wife had income tax withheld from her unearned income or she qualifies for certain credits, it can get you a tax refund.
Benefits of Filing Jointly
Filing a joint tax return when you are married provides several benefits. First, you can take advantage of a number of credits and deductions that you can’t claim if you file a separate return. In addition, the government gives the highest standard deduction to taxpayers using the married filing jointly status. If you choose to file a separate return, the standard deduction is half of what you would get filing a joint return. This can make a big difference in the amount of your income subject to tax. A lower taxable income can also qualify you for more tax credits. One of the most important advantages to your wife if she doesn’t work is that by filing jointly she can contribute to an IRA account.
Paying Less Tax
One of the biggest reasons for filing a joint return is to pay less tax. A joint return works by combining you and your spouse’s income and deductions on a single return. Usually, filing jointly reduces the tax liability for couples with one unemployed partner. If you earn a decent income but your wife has no earnings from employment to report, your income gets taxed at a lower rate.
However, if your wife has minimal income from sources other than employment, but that income is low, she may be able to write off more of the expenses than she could on a joint return. For example, a spouse with considerable medical expenses can itemize them as deductions. However, both of you must itemize deductions if you file separate returns.
