A client recently had their tax return completed by their accountant. The client is self employed and has a Simple IRA for himself and his employees. On the 2012 tax return, the client reported employer matching contributions to each of the employees Simple IRA accounts. However, the client forgot to make those contributions, and this was not discovered until they had their 2013 tax return prepared recently. According to their acocuntant, they need to make those 2012 employer match contribuitons right away, and it is legal to do so. Our understanding is that the 2012 contributions would need to have been made by Oct. 15 of 2013. Can our client make 2012 employer match contributions for his employees today?

Thanks!
