Do you mail your federal and state taxes together

In the United States, you can mail your federal and state taxes separately, but it's generally recommended to mail them together to ensure accuracy and efficiency. Here's why:

Why mail them together:

  1. Convenience: Mailing your federal and state taxes together can simplify the process and reduce the risk of errors or lost documents.
  2. Accuracy: When you mail them together, you can ensure that your federal and state tax returns are accurately matched, which can help prevent delays or errors in processing.
  3. Streamlined processing: Many states and the IRS have streamlined processing systems that can quickly and accurately match your federal and state tax returns when they're filed together.

When to mail them separately:

  1. If you have a state-specific issue: If you have a specific issue with your state tax return, such as a refund or audit, it may be necessary to mail your state tax return separately.
  2. If you're filing an amended return: If you need to file an amended return for either your federal or state taxes, it's generally recommended to mail the amended return separately to ensure accuracy and avoid confusion.

Tips for mailing your taxes:

  1. Use the correct mailing addresses: Make sure to use the correct mailing addresses for your federal and state tax returns. You can find these addresses on the IRS and your state's tax authority websites.
  2. Use certified mail: Consider using certified mail with return receipt requested to ensure that your tax returns are received by the IRS and your state tax authority.
  3. Keep a copy: Keep a copy of your tax returns and supporting documents for your records, in case you need to refer to them later.

In summary, while you can mail your federal and state taxes separately, it's generally recommended to mail them together to ensure accuracy, convenience, and streamlined processing.
