Colorado is one of the most affordable states to form and maintain an LLC. This guide to LLC formation in Colorado explains the filing, the periodic report and Colorado taxes.
Colorado's online filing is quick and its fees are low. However, the annual periodic report is still required. Therefore, set a reminder.
Our attorneys form Colorado LLCs and draft operating agreements at fixed prices.
Filing your Colorado LLC
Colorado LLCs are formed by filing Articles of Organization with the Colorado Secretary of State online. State fees change from time to time, so confirm the current amount when you file. Colorado's fees are among the lower ones in the country.
You must appoint a registered agent with a Colorado address. The name must include "LLC" or similar. Our LLC Formation service, from $99, handles the filing.
Colorado periodic reports
Colorado LLCs file a periodic report each year, during a window around the anniversary month of formation. The fee is low.
Missing the report can lead to delinquency and, eventually, loss of good standing. Our annual report filing service tracks it.
Colorado taxes
Colorado has a flat personal income tax. Pass-through LLC income flows to members. In addition, Colorado has state and local sales taxes, with many home-rule cities administering their own.
Therefore, businesses selling goods should register for sales tax carefully. Consequently, local rules matter.
Your Colorado operating agreement
Filing creates the LLC, but the operating agreement decides how it works. Without one, Colorado's default rules apply, and they may not match your deal.
A strong agreement sets ownership percentages, capital contributions, profit allocations and distributions. Moreover, it sets voting rules and whether members or managers run the company. In addition, it plans for exits: death, divorce, disability or a member who simply wants out. A buy-sell agreement can add detail on valuation and payment.
Colorado does not require you to file the operating agreement with the state. However, banks, investors and courts often ask for it. Our LLC Operating Agreement service drafts a Colorado-ready agreement, starting at $79.
LLC or corporation in Colorado?
Most small businesses in Colorado choose an LLC for its flexibility and simple taxes. By default, a single-member LLC is taxed like a sole proprietorship, and a multi-member LLC like a partnership. Moreover, an LLC can elect S corporation tax treatment if it qualifies, which can reduce self-employment tax for profitable businesses.
However, a corporation is sometimes better. For example, startups seeking venture capital usually need a C corporation, often formed in Delaware and registered in Colorado. In addition, Colorado corporations also file periodic reports, so paperwork is similar either way.
Consequently, compare both before you file. Our business formation consultation walks through the trade-offs, and our corporation formation service sets up corporations when needed.
Your first month after forming a Colorado LLC
Forming the LLC is only the first step. Next, obtain an Employer Identification Number from the IRS. It is free and usually issued online the same day. Then open a business bank account in the LLC's name, so business and personal money stay separate.
After that, register with the Colorado Department of Revenue where needed, and check home-rule city sales tax and licensing. Moreover, if you will hire employees, register for unemployment insurance and set up payroll withholding.
Finally, sign your operating agreement and store it with your formation documents. In addition, calendar recurring deadlines, such as annual reports and tax filings. Consequently, your LLC starts life organized and compliant.
Protecting your liability shield in Colorado
An LLC protects your personal assets only if you treat it as a separate business. Courts in Colorado, like courts elsewhere, can disregard the LLC in serious cases of abuse, often called piercing the veil.
Therefore, sign contracts in the LLC's name, keep business money in a business account and keep the LLC adequately funded. In addition, carry appropriate insurance, because an LLC does not protect you from your own personal negligence. Consequently, good habits from day one keep your protection strong.
If you operate in other states too, you may need to register there. Our foreign qualification service handles those filings. For the national picture, read our national guide to LLC formation and corporate structuring.
Common Colorado LLC mistakes
The most common mistake is missing a state deadline. In Colorado, that means the periodic report filed around the anniversary month. Consequently, set a recurring reminder or use a compliance service.
Another frequent problem is missing home-rule city sales tax registration. As a result, owners face penalties they did not expect. Therefore, confirm state and local tax registrations in the first month.
Similarly, many owners skip the operating agreement, mix personal and business money, or sign contracts in their own name. Each of these weakens liability protection. Finally, some owners forget to update the Secretary of State when addresses or managers change. Consequently, important notices can go astray.
Choosing a name and registered agent in Colorado
Your LLC name must be distinguishable from other names on file with the Secretary of State. Therefore, search the state database before filing. In addition, check that a matching domain name and social media handles are available.
A name search is not a trademark search. Even if Colorado accepts your name, another business may hold trademark rights to it. Consequently, consider a trademark search before investing in branding.
Next, choose a registered agent. The agent must have a physical address in Colorado and be available during business hours to receive legal papers. Many owners use a professional agent service for privacy, because the agent's address appears in public records instead of their home address.
Single-member vs. multi-member LLCs in Colorado
A single-member LLC has one owner. It is simple to run, and for federal tax it is usually treated as a disregarded entity. However, a written operating agreement still helps prove the LLC is separate from you.
A multi-member LLC has two or more owners. By default, it files a federal partnership return, and each member receives a Schedule K-1. Moreover, its operating agreement must cover voting, profit sharing and exits in detail. Consequently, Colorado owners with partners should invest more care in the agreement from the start.
