Denver's CPA market is characterized by Colorado's unique combination of industries — oil and gas extraction, legal cannabis operations (with Section 280E complexity), aerospace and defense, and a growing tech sector. Colorado's 4.4% flat income tax is relatively straightforward, but the state's unique industries require CPAs with specialized federal expertise.
Colorado CPAs are licensed by the Colorado State Board of Accountancy. Colorado has a 4.4% flat income tax (reduced from 4.55% in 2023 under TABOR) with generally good federal conformity. Cannabis businesses face Section 280E federal tax treatment — CPAs cannot deduct ordinary business expenses for federal or state filing purposes.
Section 280E cannabis returns in Denver command significant premiums — the complexity of separating COGS (deductible) from operating expenses (non-deductible) under 280E requires specialized knowledge available at few general-practice CPA firms.
