How Colorado treats self-employment deductions

  • Half of self-employment tax: deductible. Inherited: federal taxable income already reflects the deductible half of SE tax.
  • Self-employed health insurance: deductible. Inherited through federal taxable income.
  • SEP-IRA / solo 401(k) contributions: deductible. SEP-IRA and solo 401(k) deductions are inherited through federal taxable income.
  • Federal QBI deduction: kept. Federal taxable income is after the QBI deduction, so Colorado keeps it, except single filers with AGI over $500,000 and joint filers over $1,000,000 must add it back.

How the calculator handles Colorado

  • Flat 4.4% rate for tax year 2026 (DOR 2026 DR 0104EP worksheet). The TABOR-triggered temporary rate reduction does not apply to 2026.
  • Colorado starts from federal taxable income, so the federal standard (or itemized) deduction is already applied; Colorado standard deduction and personal exemption are therefore 0 here.
  • For tax years 2026 and later, taxpayers with federal AGI over $300,000 must add back federal standard or itemized deductions in excess of $1,000 (single) / $2,000 (joint). This addback is not modeled, so tax is understated above $300,000 AGI.
  • Taxpayers with AGI over $500,000 (single) or $1,000,000 (joint) must add back the federal QBI deduction (made permanent from 2026 by HB25B-1001); not modeled.
  • Colorado subtractions (e.g., state income tax refunds, pension/Social Security subtraction), credits (e.g., Colorado EITC and child tax credit) and Colorado AMT are not modeled.

Local income taxes in Colorado

No Colorado locality taxes income. Several cities (e.g., Denver) levy flat monthly occupational privilege (head) taxes on workers and businesses, which are not income-based and are not modeled.

Colorado estimated tax payments

  • Who must pay: Required if you expect to owe more than $1,000 of Colorado net tax for 2026 after withholding and credits.
  • 2026 due dates: April 15, 2026, June 15, 2026, September 15, 2026, January 15, 2027
  • Safe harbor: Required annual payment is the smaller of 70% of 2026 net Colorado tax or 100% of 2025 net Colorado tax (110% if 2025 federal AGI exceeded $150,000, or $75,000 MFS); the prior-year method requires a full 12-month 2025 Colorado return.
  • Form: Form DR 0104EP (or Revenue Online)
