Can i mail multiple year tax returns in one envelope

According to the IRS, you can mail multiple year tax returns in one envelope, but there are some guidelines to follow:

1. Use a single envelope: You can mail multiple year tax returns in a single envelope, but make sure to use a sturdy envelope that can withstand the mailing process.
2. Use a separate cover sheet: Create a separate cover sheet with the taxpayer's name, address, and identification number (Social Security number or Individual Taxpayer Identification Number). This will help the IRS process the returns more efficiently.
3. Label each return: Clearly label each tax return with the year and the taxpayer's name. For example, "2020 Form 1040" or "2019 Form 1040A".
4. Use the correct postage: Make sure to use the correct postage for the total weight and size of the envelope.
5. Keep a copy: Keep a copy of each tax return and supporting documents for your records.

Some additional tips:

• If you're mailing multiple returns for the same taxpayer, you can use a single envelope, but make sure to use a separate cover sheet for each year.
• If you're mailing returns for multiple taxpayers, you can use separate envelopes for each taxpayer.
• If you're using a certified mail service, you'll need to use a separate envelope for each return.

Remember to check the IRS website for any specific guidelines or requirements for mailing tax returns.
