As the 2022 tax filing season races toward its end, there are some dates to remember to ensure your returns make it to their destination as required. September 15 is the final extended due date for all S-Corporation returns and Partnerships. October 16, 2023 is the final extended deadline to have all Personal, Trust and Corporation income tax returns submitted. If an extention was not filed for your returns prior to the March 15 or April 18 original due dates, the returns are considered late when filed. Fines may be assessed for late filings and interest and penalties will be assessed on any tax due at the time of filing those returns.
