There is no change in the due date for filing sales and use tax returns. Returns and payment are due on the 20th of each month.

Please file your monthly sales & use tax return with the City. If full payment is not included the City will waive penalties and interest as long as the tax filer files the return and makes contact with the City to make payment arrangements. 
 
The Sales Tax Division is available by phone at 303-651-8672 or by email at Sales.tax@longmontcolorado.gov. 
 
Sales tax returns and payments can still be made by mail or online at  https://www.longmontcolorado.gov/departments/departments-e-m/finance/sales-and-use-tax/online-sales-and-use-tax-return.
