What qualifies as a ‘signed’ tax return?

To qualify as a ‘signed tax return’ the document must either:

• Be signed by at least one of the tax filers. The signature must be on the line on the tax return designated for the signature of the tax filer.
• Or, include the tax preparer’s stamped, typed, signed, or printed name and SSN, EIN (Employer Identification Number), or PTIN (Preparer Tax Identification Number).

If your tax return includes neither the signature of at least on of the tax filers nor the preparer’s certification, it does not qualify as a ‘signed tax return’.
