Gig Workers in Colorado: taxes and retirement for 2026
For rideshare and delivery drivers, shoppers and app-based workers in Colorado. Colorado has a flat 4.4% state income tax for 2026. Here are the 2026 rules, a worked example and the official sources.
Colorado rules for gig workers
- State income tax (2026)
- Colorado has a flat 4.4% state income tax for 2026. The statutory rate is 4.40% (Proposition 121, starting tax year 2022), and the 2026 DR 0104EP worksheet figures estimated tax at 4.4%. Under SB24-228 (tax years 2024 through 2034), the rate can be temporarily lowered for a tax year when TABOR surplus revenue passes set thresholds. The 2026 estimated tax form does not reflect any reduction for 2026.
- State estimated tax
- You generally must pay estimated tax if you expect to owe more than $1,000 in net Colorado tax for 2026 after withholding and credits. The required annual payment is the smaller of 70% of your 2026 tax or 100% of your 2025 tax (110% if your 2025 federal AGI was over $150,000). Same dates as federal: April 15, June 15, and September 15, 2026, and January 15, 2027. Form DR 0104EP.
- Unemployment insurance independent contractor test (C.R.S. 8-70-115)
- A worker is presumed to be in covered employment unless shown to be free from control and direction and customarily engaged in an independent trade or business related to the work. A signed written contract with the statutory clauses and a bold disclosure (no unemployment benefits; contractor pays own income taxes) creates a rebuttable presumption of independent contractor status.
- Delivery network company driver protections (HB24-1129, C.R.S. 8-4-126)
- Since January 1, 2025, delivery apps must show drivers and customers what the customer paid and what the driver receives, along with delivery distances. They must pass through 100% of tips and cannot cut base pay because of a tip. They must also publish a written deactivation policy with a challenge process and give drivers at least 60 seconds to accept an offer.
- Transportation network company transparency (SB24-075, C.R.S. 8-4-127)
- Rideshare companies must tell drivers and riders what the rider paid and what the driver was paid. Since June 1, 2025, they must follow a written deactivation and suspension policy with a reconsideration process, and starting October 1, 2025, a state-certified driver support organization can represent drivers in deactivation and suspension cases.
- State retirement program
- Colorado SecureSavings is live. It is built around W-2 employers and does not cover 1099 contractors through the employer mandate; self-employed residents can enroll on their own.
Federal rules for 2026
Mileage is the big deduction
Business miles are deductible at the IRS standard rate: $0.725 a mile for miles driven January through June 2026 and $0.76 from July 1. Keep a log of each trip; Gigaverse lets you start and stop trips in the app.
App fees and phone
Platform service fees, a business share of your phone and plan, insulated bags and parking or tolls while working are deductible.
Self-employment tax
On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
A worked example
| Mileage deduction | $11,138 |
|---|---|
| Net profit after mileage | $33,863 |
| Self-employment tax | $4,785 |
| Self-employment tax the mileage saves | $1,574 |
Miles split evenly between the two 2026 rates. Federal figures only; the mileage also lowers income tax. Computed from 2026 IRS limits (Notice 2025-67, Rev. Proc. 2025-32) and the SSA wage base.
