End of Tax Year Preparation 2021

Attention Southwestern Payroll Clients

It’s time to start gathering all the details of the past year! Don’t forget to submit the following to us for processing by December 31st in order to be included on the employee’s W-2.

  • All year-end adjustments
  • Supplemental payrolls
  • Cost of Healthcare amounts
  • W-2 Additions (i.e., personal use of company auto)

Any adjustment received after December 31, 2021, will not be addressed until after January 20, 2021. Those adjustments will then be processed on Form W‐2c and may accrue extra processing fees as well as penalties and interest on late tax deposits.

Third-party sick pay amounts will have a separate deadline. If we are aware of your third-party sick pay, we will contact you, but it is your responsibility to make sure we are aware that you will be reporting third-party sick pay amounts.

END OF YEAR CHECKLIST 2021

We will begin processing W-2s in the first week of January.

All employee data must be current in our system by December 31st, including SSNs, addresses, name changes, etc.
