Do you prepare and file information slips for clients? If so, make sure to include an early December 2nd closure of electronic services in your scheduling. Slips that are filed late or using the incorrect method will result in financial penalties to your business. The hard stop will be December 1st and services will not reopen until January 13th, 2025. In addition to the earlier shut down, information returns filed after January 1, 2024, containing five or more slips must be filed electronically.
