To receive a six-month extension of time to file your income tax form, file Form IN-151 on or before April 15.
An extension only allows more time to file the income tax return. It does not extend the due date for tax payment.
Interest and penalty accrue on tax due from April 16 to the receipt of payment.
NOTE: An extension to file an income tax form does NOT apply to Homestead Declaration or Property Tax Adjustment Claim (HS-122) or Renter Rebate Claim (PR-141).
