The year has almost come to an end. Just a handful of things left to do. The term “Burning The Midnight Oil” comes to mind. Some things need to be done and date stamped on or before December 31 of each year or it does not count for the current year.
Payroll – Did you take any personal payroll (S-Corp) If not, it may impact your personal deductions.
IRA – 401K Making those final payments before midnight on December 31. (Do not wait until 11:59 PM)
Some plans allow you to make payments until April 15th (double check the dates– do not assume)
