March 15 Filing Deadline
Most S corporation returns have a filing deadline of March 15. Some short-year or fiscal year S corporation may have a different filing deadline.
The penalty for late filing of a S corporation return is $205 per shareholder per month. If you cannot file by the March 15 deadline, you can request a 5-month extension of time to file (generally until September 15) by filing IRS Form 7004. To be accepted, Form 7004 must be filed on or before the original due date of the return.
Record-Keeping Requirements
All businesses are required by law to maintain income and expense records. Record-keeping requirements are described in IRS Pub 583 Starting a Business and Keeping Records. Generally IRS requires you keep two kinds of records for all business expenses you incur or pay:
- Proof of the expense - such as a receipt or log, and
- Proof you paid the expense - such as a cancelled check, bank statement, or credit card statement.
If you have questions about recordkeeping requirements for your business, please ask our staff.
