Short answer: if you are self-employed in Colorado with a profit, you can deduct the health insurance you pay for yourself, your spouse, your dependents and children under 27, on Form 7206 and Schedule 1, line 17. Three limits apply: no month you could join an employer plan (yours or your spouse’s), no more than the business’s profit, and no cut to self-employment tax. Colorado starts from federal taxable income, which already has the deduction taken out, so it lowers your Colorado tax too, at the flat 4.4% rate.

Who Qualifies in Colorado
- You have a net profit as a sole proprietor or single-member LLC (Schedule C or F), or self-employment earnings as a partner.
- The plan is under your business. For a sole proprietor, a policy in your own name counts, from the Colorado marketplace or a private plan.
- No employer plan was open to you that month, through your own job or your spouse’s, even one you turned down.
- The people covered are you, your spouse, your dependents, or a child under 27 at the end of the year.

The Three Limits
- The spouse ruleAny month your spouse’s employer offers you a subsidized plan is out, even if you never enrolled. Count the months carefully when a spouse changes jobs.
- The profit capNo more than the business earned after the deductible half of self-employment tax and your SEP, SIMPLE or solo 401(k) contributions. The cheapest Denver metro Silver plan at 40, $6,408 a year, needs at least that much left.
- Not for SE taxIt lowers income tax only. On $72,000 of profit, self-employment tax is still about $10,173 either way.

The Deduction and the Colorado Subsidy Line
For 2027 coverage there is no premium tax credit above 400% of the poverty line: $63,840 for one person, $132,000 for a family of four. The self-employed health insurance deduction comes off before that test, so it can move you to the right side of the line.
A single 40-year-old with $72,000 of profit pays $10,173 in self-employment tax and deducts half, $5,087. Before the health insurance deduction that leaves $66,913, over the line. Deduct a year of Anthem’s lowest-cost Silver plan in Denver, $6,408, and the figure drops to $60,505, $3,335 under it.
Then the credit lowers the premium you pay, which lowers the deduction. IRS Publication 974 has the method that settles both numbers together; a licensed agent or your tax preparer can run it before you pick a plan.
What It Is Worth in Colorado for 2027
| Household | Per month | Deductible per year | Federal tax saved at 22% | At 24% | Plus Colorado tax at 4.4% |
|---|---|---|---|---|---|
| One adult, 40 | $534 | $6,408 | $1,410 | $1,538 | $282 |

Colorado income tax starts from federal taxable income and is a flat 4.4%, the Department of Revenue’s rate for 2025 (a TABOR surplus can lower it temporarily under C.R.S. 39-22-627), so a deduction taken on the federal return lowers your Colorado tax too. Colorado runs its own marketplace, Connect for Health Colorado, so the federal plan file behind the other states’ numbers on this site does not cover it. The prices here are Anthem Blue Cross and Blue Shield’s 2027 rates by rating area, one of several insurers on Connect for Health Colorado.

Common Questions
Can I deduct health insurance if I am self-employed in Colorado?
Yes, if your business has a net profit and you could not join an employer plan, yours or your spouse’s, that month. You deduct the premiums on Form 7206 and Schedule 1, line 17. Colorado starts from federal taxable income, which already has the deduction taken out, so it lowers your Colorado tax too, at the flat 4.4% rate.
Can the deduction help me qualify for a premium tax credit?
It can. The deduction lowers the income tested against the 2027 subsidy line ($63,840 for one person, $132,000 for a family of four). The credit then lowers the premium you deduct, and IRS Publication 974 settles both together.
What is Colorado’s income tax rate?
A flat 4.4% (the Department of Revenue’s 2025 rate). A TABOR surplus can lower it temporarily for a given year under C.R.S. 39-22-627.
