Colorado LLC Taxes — Step 8 of 8
The final step: understanding what you'll actually owe. As a default pass-through LLC, your profit flows to your personal return — taxed federally, hit with self-employment tax, and then Colorado's flat income-tax rate on top. Here's the full picture, with an estimator.
By default, a Colorado LLC is a pass-through entity — profits flow to your personal 1040, taxed at federal rates plus 15.3% self-employment tax (Social Security + Medicare). Colorado then applies its flat rate rate on top, starting from your federal taxable income (Colorado has no separate state standard deduction — it simply uses the federal one). This is entirely separate from the $25 Periodic Report (Step 6) and any sales tax (Step 7).

How a Colorado LLC Is Taxed by Default
An LLC itself pays no federal income tax — it's a "pass-through" entity by default. Profits flow to the owners' personal returns, where two layers of tax apply:
- Single-member LLCs report profit on Schedule C, attached to the owner's personal Form 1040.
- Multi-member LLCs file Form 1065 (informational) and issue each owner a Schedule K-1 showing their share of profit.
- Self-employment tax (15.3%) applies to net profit — this covers Social Security and Medicare, since there's no employer withholding it for you.
- Federal income tax applies via the standard progressive brackets, after the QBI deduction and standard deduction.
- Colorado's flat income-tax rate then applies on top, starting from your federal taxable income — Colorado doesn't calculate its own separate standard deduction; it simply uses the federal one baked into that starting figure.
Federal + Colorado Tax Estimator
Enter your expected net profit to estimate total federal + Colorado tax as a default pass-through LLC:
Estimate only, assumes standard deduction (no itemizing), the simplified 20% QBI deduction, and half of SE tax deducted above the line. Doesn't include the $25 Periodic Report, sales tax, local occupational taxes, or S-corp election savings. Not tax advice — consult a CPA for your specific situation.
The S-Corp Election Option
Once your LLC's profit grows substantially, electing S-corp tax status (via Form 2553) can reduce your self-employment tax burden — you pay yourself a reasonable salary (subject to payroll tax) and take remaining profit as a distribution (not subject to SE tax). This adds payroll complexity and cost, so whether it makes sense depends on salary requirements, payroll costs, total profit, and your tax situation. Colorado's flat income-tax rate rate applies the same way regardless of your federal entity election.
Colorado's flat rate is separate from everything else in this guideThe Colorado flat income tax (4.4% for tax year 2025; verify the applicable 2026 rate) has nothing to do with the $25 Periodic Report (Step 6), which is a flat filing fee regardless of profit, or sales tax (Step 7), which only applies if you sell taxable goods. Budget for all three separately — they don't offset each other.
