How To File Wage Withholding

Withholding tax filing periods are normally based on the amount of tax withheld. If you have employees, estimate how much wage withholding you expect to pay for all your employees in one year. New businesses can file quarterly or can request more frequent filing if desired.

The department determines whether an employer will be a quarterly, monthly or weekly filer based on an annual review of the amount of Colorado withholding tax that the employer reported during the prior 12-month period of July 1 through June 30.

 

 

Quarterly Filers

  • Employers whose Colorado wage withholding reported during the lookback period was less than $7,000.
  • Due dates for quarterly filers will be the last day of the month following the close of the calendar quarter. First quarter is due April 30, second quarter is due July 31, third quarter is due October 31, and the fourth quarter is due January 31.
  • File Income Withholding Tax Returns (DR 1094) supplied in a withholding tax coupon book. Remittance should be made by check or by Electronic Payment (EFT). If you file by EFT, you do not need to mail in your return.

Monthly Filers

  • Employers whose Colorado wage withholding reported during the lookback period was at least $7,000 but not more than $50,000.
  • Monthly filers must file a withholding return on or before the 15th day of the following month. For example, March Filing is due by April 15.
  • File Income Withholding Tax Returns (DR 1094) supplied in a withholding tax coupon book. Remittance should be made by check or by Electronic Payment (EFT). If you file by EFT, you do not need to mail in your return.

Weekly Filers

  • Employers whose Colorado wage withholding reported during the lookback period was more than $50,000.
  • Weekly filers must remit any Colorado withholding taxes accumulated as of any Friday on or before the third business day following that Friday. Always provide the department with a Friday date for the filing period ending date.
  • Employers who withhold more than $50,000 annually must file all payments by Electronic Funds Transfer (EFT). 

Seasonal Filers -- Employers who do not operate their business during the entire calendar year and who do not have Colorado wage withholding when the business is not operating. The employer must obtain Colorado Department of Revenue approval and inform the Colorado Department of Revenue of the months in which there will be withholding. Seasonal filers must file a return on or before the 15th business day of the month following each month of operation. Returns for scheduled months must be filed even if no taxes are withheld.
