Colorado State-Specific Tax Details (2026)
Pass-Through Entity (PTE) Tax Election
Colorado's SALT Parity Act allows partnerships and S corporations to elect to pay Colorado income tax at the entity level at the state's flat 4.4% rate, generating a federal deduction that bypasses the individual SALT cap. The election is annual and is made on form DR 1705 (or with an estimated payment on DR 0106EP); once made it is binding and irrevocable for that year for all partners/shareholders. The election remains available for tax year 2026 (Colorado published a DR 0106EP 2026 form), and OBBBA's continuation of the federal SALT cap keeps the workaround relevant. Caution: an electing entity's owners must add back the FULL federal Section 199A/QBI deduction on their Colorado return, regardless of income level.
Local & City Income Taxes
No percentage-based local income tax anywhere in Colorado. A few Denver-metro cities levy a flat-dollar Occupational Privilege Tax (OPT, a 'head tax') on workers earning at least $500/month: for 2026 Denver charges $5.75/month per employee plus $4.00/month per employee paid by the employer. Glendale, Greenwood Village, and Sheridan also impose an OPT (verify their current amounts directly). Aurora repealed its OPT effective January 1, 2025.
Entity-Level & Franchise Taxes
No franchise, gross-receipts, margin, or B&O tax. Colorado imposes a flat 4.40% income tax on both individuals and C corporations for 2026. S corporations are recognized and generally pay no entity-level income tax unless they make the SALT Parity Act election (then taxed at 4.4% at the entity level). Separately, Colorado levies an annual, locally-assessed business personal property tax on equipment and fixtures; the refundable state income tax credit that used to offset it (on the first $18,000 of value) is repealed for tax years beginning January 1, 2026 under HB25-1296, though the underlying property tax itself continues.
Colorado Tax Credits & Incentives
Businesses operating in one of Colorado's designated Enterprise Zones earn a $1,100 state income tax credit per net new employee (larger amounts for agricultural processors and enhanced rural zones); unused credit carries forward up to 5 years. Requires advance pre-certification through OEDIT.
A performance-based, eight-year Colorado income tax credit equal to 50% of the FICA paid per net new job, for expansion/relocation projects creating at least 20 net new jobs (5 in an enhanced rural enterprise zone) at competitive wages (at least 100% of county average). Unused credit carries forward up to 10 years; it is nonrefundable.
Colorado income tax credit to defray the cost of converting to an employee-owned structure (ESOP, worker cooperative, or employee ownership trust). For applications on or after January 1, 2026, the credit covers up to 75% of qualified conversion costs, capped at $25,000 (alternative equity structures) or $40,000 (worker cooperatives / employee ownership trusts), administered by OEDIT.
Three Colorado small-business changes take effect January 1, 2026 and warrant year-end planning: (1) the sales tax vendor fee / retention allowance is eliminated (HB25B-1005), so retailers lose the ~4% (capped at $1,000/period) they could keep; (2) the business personal property tax income credit is repealed (HB25-1296); and (3) a permanent QBI add-back (HB25B-1001) requires single filers above $500k AGI / joint above $1M to add back the federal Section 199A deduction to Colorado taxable income. High-income pass-through owners should model whether a 2026 SALT Parity Act election still nets a benefit, since that election forces a FULL 199A add-back regardless of income and the federal SALT cap now sits near $40,000 under OBBBA. Confirm specifics with a Colorado tax professional.
Top Tax Strategies for Colorado Business Owners
Colorado offers a moderate tax environment. While state taxes are manageable, combining federal and state strategies can still save you thousands each year.
Flat rate simplifies planning
Colorado Enterprise Zone Tax Credits
S-Corp salary optimization
S-Corp Election in Colorado
For Colorado business owners with net income above $50,000, electing S-Corp status can save $5,000 to $20,000+ annually in self-employment taxes. As an S-Corp, you pay yourself a "reasonable salary" and take the remaining profits as distributions, which are not subject to the 15.3% self-employment tax. Keep in mind that Colorado's 4.25% flat income tax still applies to both your salary and your distributions, so the S-Corp election saves you federal self-employment tax while your state planning shifts to deductions, retirement contributions.
Example: A Denver S-Corp
A Denver business owner earning $150,000 in net business income pays themselves a reasonable salary of $60,000. The remaining $90,000 in distributions avoids the 15.3% SE tax, saving $13,770 in self-employment taxes alone — on top of whatever your Colorado state planning adds.
Retirement Plan Strategies for Colorado
Retirement plan contributions are the single most powerful tax deduction available to Colorado business owners. A Solo 401(k) allows contributions up to $69,000 in 2026 ($76,500 if you're 50+), generating tax savings of $17,000 to $24,000 at a 25-32% effective tax rate. For Colorado owners, those contributions cut both your federal bill and your 4.25% flat state income tax, stacking the savings.
SALT Deduction Impact in Colorado
Moderate SALT impact with the flat 4.25% rate. The federal SALT (State and Local Tax) deduction cap increases from $10,000 to $40,000 in 2026, providing meaningful relief for business owners in states with income taxes.
