Can i mail my partners tax return with mine

In the United States, the IRS does not require you to mail your partner's tax return with yours. In fact, each individual is responsible for filing their own tax return and is required to sign and date their own return.

However, there are some situations where it might be beneficial to file jointly, and in those cases, you would need to file a joint tax return. Here are some scenarios where filing jointly might be a good idea:

  1. Marriage: If you're married, you can file a joint tax return, which can simplify your tax preparation and potentially reduce your tax liability.
  2. Same-sex marriage: If you're in a same-sex marriage, you can also file a joint tax return, as the Supreme Court's Obergefell v. Hodges decision legalized same-sex marriage nationwide in 2015.
  3. Jointly owned assets: If you and your partner own assets jointly, such as a home or investments, filing jointly can help you report these assets and any income or losses they generate.
  4. Dependents: If you have dependents, such as children, filing jointly can help you claim the child tax credit or other dependent-related tax benefits.

If you do decide to file jointly, you'll need to sign and date both returns, and you'll need to provide your partner's Social Security number or Individual Taxpayer Identification Number (ITIN) on your return.

On the other hand, if you're not married or in a same-sex marriage, and you're not jointly responsible for any assets or dependents, you may want to consider filing separately. In this case, you would file two separate tax returns, one for each individual.

Remember to consult with a tax professional or the IRS if you're unsure about which filing status is best for you and your partner.
