Sales Tax

The City of Lamar relies on sales tax revenue to fund its operations and services. Prompt remittance of sales tax helps our City and its residents.  If you have any questions about City sales tax deadline dates, forms, or other sales tax-related questions, contact Missy Mason at 719-336-1370.

The City has attempted to make all 2025 and 2026 forms web accessible, but not all are compliant with ADA regulations. If you require assistance with accessing or understanding these documents, please contact the Clerk's office at 719-336-1370.
