Ineligible for PIN: The spouse reported is under the age of 16 and/or has never filed a tax return and/or has an invalid Pin/AGI. This rejection is typically in conjunction with rejection code R0000-503 but not always. It means that you did not enter the correct prior year Adjusted Gross Income (AGI) amount for your spouse.
Fix #1: Sign into your PriorTax account and double check the amount you entered. Update from your rejection status page if incorrect. Resubmit for filing.
Fix #2: If the amount seems correct to the best of your knowledge, you may need to paperfile your tax return for the year. You can print your return by signing into your PriorTax account. You can simply sign and mail that to the IRS for filing.
