Massachusetts Extension

Massachusetts grants an automatic six-month extension if 80% of the tax due is paid by the original due date. The extension is for filing a return, not for paying the tax due.

If 80% of the tax due for 2021 has been paid through:

  • withholding;
  • timely estimated payments of tax;
  • credits from your 2021 return;
  • an overpayment from the prior tax year applied to the next year's estimated tax,
your extension is automatic. No filing is required.

If you need to make a payment to reach the 80%, fill out Form M-4868 , Massachusetts Income Tax Extension Payment Worksheet and Voucher, and file it with your payment.
