We send our administration invoices in April of each year. This invoice covers the annual administration for the prior year. Here are the following timelines and deadlines to consider: Invoices will go out on approx. April 15th for the prior year administration. For example, you will be billed in April 2023 for the 2022 plan year. You will have 45 days to pay. Emailed invoice reminders will go out every two weeks. For example, you would be billed on April 15th and receive a reminder on May 1st, May 15th and so forth. A late fee of $50 will be assessed for each month the invoice is open starting on June 1st. So, if you pay the invoice during June you will have a late fee of $50, July late fee is $100, August $150 and so forth. Please also realize that payment must be received before July 31st if you want us to file an extension for your IRS Form 5500 filing.
