LLC Taxes in Colorado
LLCs in Colorado are pass-through entities for federal tax purposes. This means all net business income flows through to your personal tax return and is subject to federal self-employment tax (15.3% on 92.35% of net earnings up to $176,100 for Social Security, plus 2.9% Medicare on all earnings). An additional 0.9% Medicare tax applies to earnings above $200,000 ($250,000 married filing jointly).
In addition to federal taxes, Colorado applies a flat 4.4% state income tax on your LLC income. Since LLC income passes through to your personal return, it is taxed at the same rate as your other income.
Colorado offers a standard deduction of $14,600 for single filers and $29,200 for married filing jointly, which reduces your state taxable income.
If your LLC elects S-Corp status, you can potentially reduce your self-employment tax burden by paying yourself a reasonable salary and taking remaining profits as distributions. Use the calculator above to compare the default LLC treatment with S-Corp election for your specific situation in Colorado.
