Important Notice:
Opening of the 2023 Tax Filing Season
Maryland will begin processing personal income tax returns for Tax Year 2023 the same day the Internal Revenue Service (IRS) begins accepting returns (the IRS has not yet announced the date). Note: If the IRS experiences delays, these delays will postpone our opening date.
When we resume our normal processing, the online supporting tax years will be for 2021, 2022, 2023 and estimated payments for tax year 2024.
We stop processing returns and payments each year during our annual cut over period from late December to mid-January. Debits scheduled to be withdrawn between 12/26/2023 and the date we resume processing may be delayed.
