Step 1: Establish your Colorado business’s corporate income tax obligations
Most states impose taxes on corporations based on the company’s income. Therefore, the first step in meeting your business tax obligation is to verify the corporate income tax obligations for Colorado small business taxes.
Filing Requirements for Corporations in Colorado
All corporations required to file a federal tax return must file a Colorado income tax return. Business owners must file business income tax returns by the 15th day of the fourth month after the end of the company’s tax year. Many corporations choose a calendar year for their tax year. If so, the state corporate tax return would be due by April 15th of each year.
As with federal corporate tax returns, the company may file for an extension to file a Colorado corporate tax return. However, the extension is only for filing the tax return. It doesn’t extend the requirement to pay taxes.
Income Taxes for Small Businesses in Colorado
Unlike pass-through entities, corporations that earn income within Colorado must pay corporate income taxes. Pass-through entities, such as sole proprietorships and many limited liability companies, “pass through” the business income to the company owners. The owners pay personal income taxes on the business income.
Corporations pay income taxes in Colorado based on the company’s federal taxable income reported to the Internal Revenue Service. The corporation’s net income may be modified by subtractions and additions as required by Colorado tax laws. Some deductions allowed on federal tax returns aren’t permitted when calculating Colorado small business taxes.
Colorado Small Business Tax Rates
The Colorado business tax rate for corporate income taxes for tax years beginning in 2020 is 4.55%. Always verify the Colorado business tax rate because the rate is subject to change in future years.
A corporation may choose to pay business taxes in Colorado of .05% of its annual gross receipts from sales in or into Colorado instead of based on its adjusted federal taxable income. The corporation must meet these qualifications to pay taxes based on annual gross receipts:
- The C corporation must file a Colorado return
- The C corporation’s only income in Colorado must be from sales
- The company can’t own real estate or rent real estate within Colorado
- The company’s gross annual sales in or into Colorado must total $100,000 or less
Corporations in Colorado must pay estimated tax payments if the net state tax liability for the year exceeds $5,000. Business owners pay estimated income taxes in four quarterly installments equal to 25% of the total annual tax requirement.
The quarterly tax requirement equals 70% of the corporate net tax liability for the current tax year or 100% of the net tax liability for the previous year (if the corporation meets specific requirements). Estimated quarterly corporate income tax payments are due the 15th day of the month in April, June, September, and December.
Failing to remit required estimated taxes could result in a tax penalty. Tax penalties aren’t charged for corporations with less than $5,000 in net tax liability for the tax year.
Step 2: Determine your Colorado business’s employment taxes
Businesses that transact business or receive income from Colorado sources and compensate an employee for services performed must register with the Colorado Department of Revenue as an employer. Generally, whenever employee compensation is subject to federal wage withholding, the wages are also subject to Colorado wage withholding.
Employers are responsible for paying state withholding taxes, even if the employer doesn’t withhold the tax from the employee’s wages. The Colorado Income Tax Withholding Worksheet for Employers (DR 1098) explains the method for calculating wage withholding. Employers must submit wage withholding payments and file returns weekly, monthly, or quarterly, depending on the employer’s annual Colorado wage withholding liability.
Employers must prepare and file W-2 statements for each employee. The statements must be filed with the Department of Revenue and supplied to the employee by January 31st of each year.
Step 3: Establish your Colorado business’s additional state tax obligations
A Colorado small business may have additional state tax obligations. Common business tax obligations that could apply to your small business include, but might not be limited to the following.
Colorado collects sales tax on retail sales of tangible personal property. Typically, sales tax isn’t charged for services performed unless a specific law taxes the service. The Colorado Department of Revenue collects sales tax for the state and many local municipalities.
Businesses are required to collect sales tax and remit those taxes to the Department of Revenue. The company must also maintain a sales tax license. The filing requirements and due dates for sales tax are determined when the business receives its license but could be changed in the future. Businesses can find more information about Colorado sales taxes on the Sales & Use Tax page on the state’s website.
Franchise or Privilege Tax
A franchise or privilege tax is an amount imposed on a company for doing business within a state. Franchise taxes may be a flat fee or based on a company’s net worth. Colorado doesn’t impose franchise or privilege taxes.
Most employers are subject to unemployment taxes if they pay wages of at least $1,500 or more in a calendar quarter or employ at least one person for at least one day during 20 weeks in a calendar year.
Unemployment tax is based on employee wages. There is an annual maximum amount a small business must pay in Colorado unemployment taxes. Quarterly reports and premium payments are due by the last day of the month in April, July, October, and January.
Excise taxes are taxes on specific goods, activities, and services. These taxes are in addition to any sales tax charged by the state. For example, Colorado imposes excise taxes on several products, including cigarettes, nicotine products, tobacco products, liquor, marijuana, and fuel.
Small businesses must apply for a license to sell these products. The filing and payment requirements for excise taxes depend on the type of product being sold.

There are several steps that successful small businesses take as they prepare to file and pay their taxes.
