I wrote 2 payroll checks in December 2013 and the year it printed on the check was 2014. So, in my quickbooks program everything is now incorrect. Problem was not found until today which means the payroll tax numbers are incorrect along with the company end of year and the employee W2. Is there an easy way to fix this?
Thanks!

You will need to amend the Forms 941 that were submitted in January.

The answer is NO, there is NO easy way to fix this.
