Local Laws Overview

When operating an online business in Denver, key local and state legal issues to understand include the following:

• Sales and use tax - Colorado and Denver collect sales and use taxes. Denver imposes its own local sales tax in addition to the Colorado state sales tax. If your business has nexus with Colorado or Denver - for example by having substantial in-state sales, inventory, employees, or a physical presence - you may be required to collect and remit state and local sales taxes. Colorado also has economic nexus rules for remote sellers and marketplace facilitators that can create tax collection obligations even without a physical presence.
• Business licensing and registration - Denver requires business registration and certain licenses for merchants and businesses operating in the city. Online sellers based in Denver should register with local business licensing authorities and with the Colorado Department of Revenue as appropriate.
• Consumer protection - Colorado law, including the Colorado Consumer Protection Act, and corresponding local enforcement protect consumers from deceptive business practices. The Colorado Attorney General enforces state consumer protection rules; Denver may also have local consumer complaint processes.
• Data privacy and breach notification - Colorado enacted the Colorado Privacy Act, which requires certain disclosures and consumer rights when applicable. Colorado also has data breach notification rules requiring timely notice to affected residents and state authorities in many cases. These state requirements operate alongside federal laws such as COPPA for children and sector-specific rules for financial and health data.
• Accessibility - While the law is primarily federal under the Americans with Disabilities Act, Denver-based businesses that are public accommodations should consider website and app accessibility. Courts and demand letters have challenged inaccessible websites, so following accessibility best practices - for example Web Content Accessibility Guidelines - reduces litigation risk.
• Advertising, marketing and email rules - Federal rules such as the FTC Act and CAN-SPAM govern online advertising, endorsements and commercial email. State laws in Colorado can add consumer protections or additional prohibitions against unfair practices.
• Intellectual property protections - Trademarks, copyrights, domain name disputes and DMCA takedowns are handled under federal law, but enforcement often involves local counsel and local courts when litigation occurs in the Denver area.

Because tax rates, licensing requirements and enforcement priorities change, businesses should confirm current Denver and Colorado rules before relying on a specific practice.

Frequently Asked Questions

Do I need to collect Denver sales tax for online sales?

It depends on whether you have tax nexus with Colorado or Denver. Nexus can be created by a physical presence such as inventory, employees or offices in Colorado, or by economic thresholds for remote sellers and marketplace facilitators. If you meet Colorado or Denver thresholds, you must register, collect and remit the proper state and local sales taxes. Consult a tax advisor or lawyer to determine your nexus status and registration obligations.

What is Colorado economic nexus for remote sellers?

Colorado has economic nexus rules that can require remote sellers and marketplace facilitators to collect Colorado sales tax if they exceed certain sales thresholds into the state. Threshold amounts and the specifics for counting transactions may change over time, so check current law and consult an accountant or lawyer to confirm whether your sales meet the threshold and whether marketplace facilitator rules shift collection responsibility to a third-party marketplace.

Do I need a privacy policy for my website or app?

Yes. A privacy policy is required by many laws and is a baseline best practice. State privacy laws such as the Colorado Privacy Act, federal requirements for certain sectors, and platform or payment processor rules often require clear disclosure of how you collect, use, share and secure personal data. If you serve children, you may also need to comply with COPPA and provide parental notices. A tailored privacy policy prepared or reviewed by counsel will better reflect your practices and legal obligations.

What should I do if my business has a data breach?

Act quickly - contain the breach, preserve evidence, and follow your incident response plan. Assess the scope of affected data and determine whether state or federal breach-notification laws apply. Colorado law and other laws may require prompt notice to affected residents and to state authorities. Consider engaging legal counsel and cybersecurity professionals immediately to guide communications, compliance, and mitigation steps. Legal counsel helps manage regulatory risks and preserves privilege for internal investigations.

How do I protect my trademarks and brand online?

Choose a distinctive mark, search existing trademarks and domain names before using the mark, and consider registering your trademark with the U.S. Patent and Trademark Office. Monitor marketplaces and the web for infringing uses, issue cease-and-desist or DMCA notices when appropriate, and be prepared to enforce your rights in federal court or through domain dispute forums. A local attorney can help with clearance searches, registration filings and enforcement strategies.

Are my online terms of service and return policy enforceable in Denver?

Yes, properly drafted and presented terms of service and refund policies can be enforceable. To improve enforceability, make terms clear, conspicuous, and reasonably accessible before purchase or account creation. Include choice-of-law and dispute resolution clauses if appropriate, but be aware that consumer protection laws may limit or override some contract provisions. Having an attorney draft or review these documents will reduce litigation risk and ensure compliance with Colorado consumer laws.

What rules apply to email marketing and online advertising?

At the federal level, CAN-SPAM sets requirements for commercial email - including opt-out mechanisms and truthful header information. The FTC enforces rules on deceptive advertising and endorsements. State consumer protection laws also apply. If you work with influencers or affiliates, ensure disclosures meet FTC endorsement guidelines. Maintain records of consent for marketing communications and honor unsubscribe requests promptly.

Can I be sued for an online customer review or comment?

Possibly. Defamation claims can arise from false, harmful statements. However, many online platforms provide some protections, and the standards for proving defamation are strict. If you face a defamatory review, document the statements, avoid retaliatory conduct, and consult an attorney to evaluate legal options such as takedown requests or litigation. Conversely, be careful issuing public statements about customers - avoid false or misleading claims.

Do I need to comply with accessibility standards for my website?

While federal ADA rules are still evolving with respect to websites, many businesses face accessibility demands or litigation where websites are not reasonably accessible. Following accessibility best practices such as Web Content Accessibility Guidelines helps reduce legal exposure and improves usability for customers. Consider an accessibility audit and remedial plan, and consult counsel for guidance tailored to your business and risk tolerance.

What if a platform like a marketplace suspends my account?

First, review the platform's terms of service and reason for suspension. Document communications, respond through the platform appeal process, and preserve evidence showing compliance. If suspension causes substantial harm, speak with a lawyer about possible contractual remedies or temporary relief, keeping in mind that many marketplace agreements favor the platform. Early legal advice can help evaluate options and negotiate reinstatement or settlement.
