One of the hardest things to keep track of as a CPA who prepares income taxes is the due date of tax returns, income tax estimates and other filings. Normally, these due dates fall on the 15th of a month. However, if the 15th is a Saturday, Sunday or federal holiday, the due date rolls over to the next business day.
Looking at a calendar for what the actual due date is can sometimes be confusing. For example, in my post yesterday, I referred to the farmer's tax estimate being due on Jan. 16 this year since Jan. 15 falls on a Sunday. I had looked at my calendar and noted those dates. However, my calendar did not tell me that the Martin Luther King federal holiday is on Jan. 16. Therefore, the actual due date is Tuesday, Jan. 17, not Monday, Jan. 16.
Just remember that if a tax filing due date is on a weekend day or federal holiday, it automatically rolls over to the next business day.
