What do Denver CPAs typically charge for individual tax returns?

In Denver's market, individual returns typically run $250-$500 for straightforward situations. Returns with investment income, rental properties, or self-employment income generally range from $450-$900. These are slightly below major coastal markets (NYC, SF) and comparable to other secondary cities like Austin and Nashville. Rates at downtown Denver firms tend to run 15-20% higher than suburban practices.

Are there Denver CPAs who specialize in Colorado-specific tax issues?

Yes. Colorado has a flat state income tax rate of 4.4% in 2026, but there are important Colorado-specific items: the Taxpayer's Bill of Rights (TABOR) refund mechanism, Colorado-specific deductions and subtractions, property tax exemptions for primary residences, and Colorado enterprise zone credits for businesses operating in designated areas. Denver CPAs who work primarily with Colorado businesses will be familiar with all of these.

What industries do Denver CPAs specialize in?

Denver's economy drives several specialty niches: energy and natural resources (oil, gas, and mining companies), real estate and construction (a major sector given Denver's growth), technology and startups (the Denver-Boulder tech corridor), cannabis businesses (Colorado's established legal market), and outdoor and recreation businesses. Finding a CPA with industry experience in your sector is worth the effort.

How do I find a Denver CPA who handles cannabis business taxes?

Cannabis businesses in Colorado face unique federal tax challenges under IRC §280E, which disallows deductions for businesses trafficking Schedule I controlled substances — meaning cannabis businesses can only deduct cost of goods sold, not normal operating expenses. This creates effective tax rates far above other industries. Seek a CPA who specifically mentions cannabis tax experience, ideally with references from Colorado dispensary or cultivation clients.

Do Denver CPAs handle Colorado sales tax for businesses?

Colorado has a notoriously complex sales tax system — the state rate is 2.9%, but home rule municipalities (including Denver at 4.81% city sales tax) administer their own rates and rules independently. Denver businesses selling into multiple municipalities need a CPA or sales tax specialist who understands the Colorado home rule structure. Some Denver CPA firms have dedicated sales tax practices for this reason.

Denver's CPA Market: What You're Working With

Denver has grown rapidly over the past decade, and its accounting market reflects a maturing economy: a mix of large regional firms (Plante Moran, FORVIS Mazars, Eide Bailly all have significant Denver presence), mid-size boutique firms, and solo practitioners. The market is large enough to find specialists in almost any industry or tax situation, and competitive enough that fees remain below coastal equivalents.

Denver's economy is diversified — energy, real estate, technology, healthcare, outdoor recreation, and an established cannabis industry — which means the city's CPA firms have developed genuine specialization across these verticals. Finding a CPA who understands your specific industry is more achievable here than in smaller markets.

Colorado Tax Landscape for Denver Businesses and Individuals

State Income Tax

Colorado uses a flat income tax rate of 4.4% for both individuals and corporations in 2026. This simplicity is one of Colorado's competitive advantages for businesses. However, the TABOR (Taxpayer's Bill of Rights) provision requires excess state revenues to be refunded to taxpayers — the "TABOR refund" mechanism creates annual adjustments that affect effective state rates. Denver CPAs track this closely, as the refund mechanism can affect tax planning strategies year to year.

Denver City and County Tax Obligations

Denver imposes an Occupational Privilege Tax (OPT) on employees earning more than $500/month — $5.75/month for each employee and an employer match of $4.00/month per employee. Small as this sounds, it's a compliance obligation that catches out-of-state employers hiring Denver workers off guard. Denver also levies a business personal property tax on assets used in your business — an annual filing requirement often missed by small business owners.

Colorado Sales Tax Complexity

Colorado has one of the most complex sales tax systems in the country because of its home rule structure. Over 70 home rule municipalities — including Denver — administer their own sales tax rates and rules independently of the state. Denver's combined sales tax rate is approximately 8.81% (2.9% state + 4.81% city + other local taxes). Businesses selling into multiple Colorado cities need careful tracking of which rates apply where — a topic where a Denver CPA with sales tax experience earns their fee quickly.

Cannabis Business Taxes in Colorado

Colorado's legal cannabis industry is one of the largest in the country, but federal law creates a punishing tax environment under IRC §280E: because cannabis remains a Schedule I controlled substance federally, cannabis businesses cannot deduct ordinary business expenses — only cost of goods sold. Effective federal tax rates for cannabis businesses often run 50-70% of net income. CPAs serving this industry must structure COGS carefully and navigate the tension between federal and state tax treatment.

If you operate in the cannabis space, this is non-negotiable: find a CPA with specific Colorado cannabis experience, not a generalist who will learn on your dime.

When Denver Businesses Typically Need a CPA

Denver's growth has created a steady stream of first-time business owners who've never worked with a CPA. The most common situations where Denver business owners seek out professional help:

Entity selection for new businesses — LLC vs. S-corp vs. C-corp, particularly for tech companies considering VC funding from the Boulder-Denver startup ecosystem
Real estate investment — Denver's hot real estate market has created a large base of rental property investors navigating depreciation, 1031 exchanges, and passive activity rules
Multi-state tax issues — Denver serves as a hub for mountain west businesses with operations in multiple states (Colorado, Utah, Wyoming, Montana), creating nexus and apportionment questions
Energy sector tax — oil and gas operations have specific intangible drilling cost deductions, depletion allowances, and tax credit opportunities that require specialized knowledge

What to Look for in a Denver CPA

Beyond the standard license verification (Colorado State Board of Accountancy at dora.colorado.gov), look for:

Industry experience in your specific sector — Denver's specialization makes this achievable
Colorado-specific knowledge — TABOR refund mechanics, OPT compliance, Colorado enterprise zone credits, home rule sales tax
Proactive communication — does the CPA reach out during the year with relevant planning opportunities, or only during tax season?
Technology integration — modern Denver firms use cloud accounting (QuickBooks Online, Xero), secure portals, and automated bill processing; paper-based workflows are a yellow flag

Typical CPA Fees in Denver (2026)

Individual return (simple): $250-$450
Individual return with investments/rental: $450-$800
Small business return (S-corp or LLC): $900-$2,500
Monthly bookkeeping: $300-$1,200/month depending on transaction volume
Tax planning consultation: $400-$1,500
