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 4.4% 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 4.4% 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 4.4% 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 it typically only makes sense once net profit clears roughly $60,000–$80,000/year. Colorado's flat 4.4% rate applies the same way regardless of your federal entity election.
Colorado's flat rate is separate from everything else in this guideThe 4.4% income tax 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.
