How Colorado LLCs are taxed
Colorado LLCs don't pay income tax at the business level. Instead, profits pass through to the owners, who report them on their personal tax returns and pay state and federal income tax there. On top of that, LLC members owe self-employment tax, and businesses with employees take on payroll tax obligations as well.
Most Colorado LLC owners end up dealing with 4 categories of tax: state income tax, federal income tax, self-employment tax, and — if they sell taxable goods or services — sales tax. If you have employees, payroll taxes add another layer. The sections below break down each one.
- State income tax on your share of LLC profits
- Federal income tax on your share of LLC profits
- Self-employment tax (Social Security and Medicare) on net earnings
- Sales tax if you sell taxable goods or certain services in Colorado
- Payroll taxes if you pay employees
Colorado state income tax
Colorado taxes individual income at a flat 4.4% rate for tax year 2024. Because an LLC's profits pass through to its members, each member pays this rate on their share of the business income — the LLC itself doesn't file a Colorado income tax return.
Colorado doesn't have a franchise tax or a separate business privilege tax, which keeps the state tax picture relatively straightforward for most LLC owners. You'll report your Colorado business income on your individual Colorado income tax return using Form DR 0104.
One thing that catches people off guard: if your LLC has members who live outside Colorado, those nonresident members may still owe Colorado income tax on their share of income earned in the state. A tax professional can help you figure out the right approach for multi-state situations.
Colorado sales and use tax
Colorado has a statewide sales tax rate of 2.9%. On top of that, counties, cities, and special districts can add their own rates — the combined rate in some areas reaches 11.2% or higher. If your LLC sells taxable goods or certain services, you need to collect and remit sales tax to the Colorado Department of Revenue.
Colorado's sales tax structure is more complex than most states because local jurisdictions often administer their own taxes separately from the state. If you sell in multiple Colorado cities or counties, you may need to register with each jurisdiction individually. The Colorado Department of Revenue's Sales Tax Guide is the best starting point for figuring out your specific obligations.
Use tax applies when you buy taxable goods outside Colorado for use in the state without paying sales tax at the time of purchase. If that applies to your business, you'll report and pay use tax on your Colorado return.
Federal income tax and self-employment tax
At the federal level, how your LLC is taxed depends on how many members it has and whether you've made an election to change the default classification.
Single-member LLC
A single-member LLC is treated as a disregarded entity by default. You report business income and expenses on Schedule C of your personal Form 1040. You also owe self-employment tax — 15.3% on net earnings up to the Social Security wage base, then 2.9% on earnings above that — which covers your Social Security and Medicare contributions.
Multi-member LLC
A multi-member LLC is treated as a partnership by default. The LLC files Form 1065 with the IRS and issues a Schedule K-1 to each member showing their share of income. Each member then reports that income on their personal return and pays self-employment tax on their share of net earnings.
S Corporation election
An LLC can elect S Corporation tax treatment by filing Form 2553 with the IRS. Under this structure, you pay yourself a reasonable W-2 salary and only that salary is subject to self-employment tax — the remaining profits pass through without it. This can reduce your self-employment tax bill, but it adds payroll administration. A tax professional can help you figure out whether the math works for your situation.
Payroll taxes for Colorado LLCs with employees
If your Colorado LLC pays employees, you take on payroll tax obligations at both the federal and state level. These are separate from the income and self-employment taxes you pay as an owner.
- Federal income tax withholding: withhold from employee wages and remit to the IRS on a deposit schedule based on your payroll size
- Social Security tax: withhold 6.2% from employee wages and match it as the employer, up to the annual wage base
- Medicare tax: withhold 1.45% from all employee wages and match it; an additional 0.9% applies to wages over $200,000 for single filers
- Federal unemployment tax (FUTA): paid by the employer only, not withheld from employees
- Colorado state income tax withholding: withhold Colorado income tax from employee wages and remit to the Colorado Department of Revenue
- Colorado unemployment insurance (UI): register with the Colorado Department of Labor and Employment and pay UI premiums based on your assigned rate
Payroll tax deadlines are strict, and getting behind can mean penalties and interest. Most small businesses use payroll software or a payroll service to stay on schedule. A tax professional can help you set up the right deposit schedule from the start.
Estimated tax payments
Because LLC owners don't have an employer withholding taxes from a paycheck, you're generally responsible for paying taxes throughout the year in quarterly estimated payments — both to the IRS and to the Colorado Department of Revenue.
The IRS requires estimated payments if you expect to owe at least $1,000 in federal tax for the year after withholding and credits. Colorado has a similar threshold for state estimated payments. Federal estimated payments are due in April, June, September, and January. Missing a payment or underpaying can mean an underpayment penalty — even if you pay the full amount owed when you file.
Most LLC owners find it helpful to set aside 25–30% of net income each quarter to cover both federal and state estimated taxes. A tax professional can help you figure out the right amount based on your actual income and deductions.
FAQ
It depends on your LLC's structure and activities. Most Colorado LLC owners pay state income tax at the 4.4% flat rate, federal income tax, and self-employment tax on their share of net profits. If you sell taxable goods or services, you also collect and remit Colorado sales tax. If you have employees, payroll taxes apply on top of that.
No. Colorado does not have a franchise tax or a separate business privilege tax. LLC owners pay state income tax on their share of profits through their personal returns, but there's no additional annual tax levied on the business itself for the privilege of operating in Colorado.
Yes. Colorado taxes individual income at a flat 4.4% rate for 2024. Because LLC profits pass through to members, each member reports their share of business income on their personal Colorado return and pays tax at that rate. The LLC itself doesn't file a separate Colorado income tax return under the default pass-through structure.
Yes. Colorado's statewide sales tax rate is 2.9%. Counties, cities, and special districts add their own rates on top of that — combined rates in some areas reach 11.2% or higher. If your LLC sells taxable goods or certain services, you need to register with the Colorado Department of Revenue and collect sales tax from customers.
Yes, in most cases. If you expect to owe at least $1,000 in federal tax for the year, the IRS requires quarterly estimated payments. Colorado has a similar requirement for state taxes. Federal payments are due in April, June, September, and January. Not paying enough on time can mean an underpayment penalty even if you settle the full balance when you file.
It depends on how your LLC is classified. A single-member LLC reports income on the owner's personal Form 1040 — no separate LLC return. A multi-member LLC files Form 1065 with the IRS and issues Schedule K-1s to members, but members pay tax on their personal returns. An LLC taxed as an S Corporation files Form 1120-S. Colorado follows the same pass-through structure for state purposes.
Yes. Self-employment tax covers Social Security and Medicare contributions for people who work for themselves. LLC members pay 15.3% on net earnings up to the Social Security wage base, then 2.9% on earnings above that. This is separate from income tax. If your LLC elects S Corporation status, only the salary portion you pay yourself is subject to self-employment tax — not the full profit.
