US Colorado Sales Tax on SaaS, Software and Digital Products

Background

Colorado is moving from a relatively narrow state-level software tax base to a much broader one. Under current law, Colorado generally taxes tangible personal property and digital goods, but downloaded software and remotely accessed software have historically benefited from a specific exemption where the statutory criteria were not met. 

HB26 1223 changes that position from January 1, 2027, by repealing the downloaded software exemption so that software available for repeated sale or licence becomes taxable tangible personal property, subject to sales and use tax, unless it qualifies for a remaining exemption such as custom software or software under a negotiable licence agreement. 

The Colorado General Assembly bill page confirms that HB26 1223 became law, and that the governor signed it on June 4, 2026.

Colorado’s state sales tax rate base is 2.9 percent, but local jurisdictions, special districts, and home rule cities may add additional tax. Colorado is especially complex because many home rule municipalities administer their own taxes and may apply different rules or separate registration and filing requirements.

Colorado Sales Tax for Software and Digital Products

Colorado generally imposes sales tax on retail sales of tangible personal property. The Department of Revenue’s sales tax guide summary states that Colorado imposes sales tax on retail sales of tangible personal property, and that services are generally not taxed unless specifically made taxable.

Colorado’s tangible personal property rules include digital goods, and Colorado rules provide that the method of delivery does not affect taxability where the item is taxable tangible personal property. The rule commentary states that delivery methods can include compact disc, electronic download, and internet streaming.

This means Colorado should not be analysed as a state where everything digital is automatically exempt. Instead, the analysis must identify whether the transaction is taxable tangible personal property, taxable digital goods, taxable software, exempt custom software, exempt downloaded software under current law, or a nontaxable service.

Sales Tax on Prewritten Software, Custom Software, SaaS, and Cloud Access Services

Canned or prewritten software

Canned or prewritten software is software made available for repeated sale or licence. Under Colorado’s current structure, prewritten software has historically been taxable mainly where it met specific statutory conditions, including delivery in tangible medium and a nonnegotiable licence agreement. Legislative materials describing the prior exemption explain that software is not delivered in tangible medium if it is provided through an application service provider, electronic computer software delivery, or load and leave delivery.

In practical terms, before January 1, 2027, Colorado state-level tax often turns on whether the software is delivered physically or electronically and whether the software falls into the existing exemption.

Customized software

Custom software is generally software developed for a particular user. HB26 1223 preserves an exemption for software developed for use by a particular user. The enacted bill summary states that downloaded software governed by a negotiable licence agreement or developed for use by a particular user remains exempt.

A practical example would be a Colorado business hiring a foreign developer to create a bespoke internal platform, where the programme is developed specifically for that customer and is not made available for repeated sale. That fact pattern is much closer to exempt custom software than to taxable mass market SaaS.

SaaS and Remote Access to Cloud-Based Software

Under current Colorado state-level rules, SaaS has generally been treated as nontaxable because the customer does not receive software in a tangible medium and the current downloaded software exemption has effectively kept many remotely accessed software models outside the state tax base. 

SALT summaries describe current Colorado law as generally treating SaaS as nontaxable at the state level until the 2027 change.

However, this is only the state-level answer. Colorado home rule jurisdictions may already tax SaaS. Denver is the leading example. Denver imposes sales or use tax on the purchase price for software programmes, SaaS, software licence fees, and software maintenance agreements.

That means a SaaS provider may currently be outside Colorado state sales tax, but still exposed to a self-collecting local city tax where the customer uses the software in that city.

Other Digital Products

Colorado’s digital goods framework is broader than software alone. Rule guidance states that delivery method does not affect the taxability of tangible personal property and lists electronic download and internet streaming as delivery methods.

So, for digital products other than software, such as streaming or certain digital content, Colorado can already treat the transaction as taxable depending on the category.

Taxability Rules under HB26 1223 

HB26 1223 is no longer merely a proposal. The Colorado General Assembly page lists the status as Became Law, and the bill history shows that the governor signed it on June 4, 2026.

The key software change takes effect from January 1, 2027. The bill summary states that beginning on that date, the act repeals the downloaded software sales and use tax exemption so that all software available for repeated sale and licence qualifies as tangible property and becomes subject to sales and use tax. It also states that the act exempts downloaded software governed by a negotiable licence agreement or developed for use by a particular user.

The same summary clarifies that the repeal applies to the sale, storage, use, and consumption of tangible personal property on or after January 1, 2027.

What will be different, considering the taxability rules around digital products or services? 

From January 1, 2027, Colorado state sales and use tax is expected to apply much more broadly to:

• SaaS subscriptions
• Downloaded software
• Mobile applications
• Cloud-hosted software access
• Electronically delivered prewritten software
• Standard software licences
• Remotely accessed software available for repeated sale or licence

HB26 1223 is expanding Colorado sales and use tax to software regardless of delivery method, including SaaS and software accessed remotely through the internet.

Two main software exemptions remain particularly important.

Custom software

Software developed for a particular user remains exempt. This should be supported by contracts, statements of work, intellectual property terms, and development documentation showing that the customer purchased a bespoke development service rather than access to a standard product.

Negotiable licence agreement

Software governed by a negotiable licence agreement remains exempt. This is one of the most technically sensitive areas. SALT commentary notes that the statute does not fully define the term, so future Colorado Department of Revenue guidance will be important. 

A standard SaaS subscription accepted through online terms will likely be taxable from 2027.

A large enterprise software licence individually negotiated, signed by authorised representatives, and materially modified between the parties may have a stronger exemption argument, depending on the final guidance and facts.

Remote Seller Framework

Colorado applies an economic nexus threshold to remote sellers. The Colorado Department of Revenue sales tax guide search result states that if a retailer’s Colorado sales in the previous year exceed USD 100,000, the retailer is subject to Colorado sales tax licensing and collection requirements.

Remote seller guidance also confirms the USD 100,000 threshold and notes that Colorado removed the separate 200 transaction threshold.

For software and SaaS providers, this means:

• A remote provider below the Colorado threshold may not be required to collect Colorado state sales tax.
• A remote provider above the threshold must register and collect on taxable Colorado sales.

From 2027, many SaaS and cloud software receipts that were previously not taxable at the state level may become part of the taxable collection framework.

Foreign providers are not excluded from this rule. If a non-US SaaS provider or digital product seller exceeds Colorado’s remote seller threshold and sells taxable products or services into Colorado, it should review Colorado registration and collection obligations.

Marketplace Facilitators and Marketplace Sellers

Colorado marketplace rules shift collection responsibility to marketplace facilitators for marketplace sales. Colorado’s own online seller guidance states that, as of October 1, 2019, marketplace sellers are no longer required to collect and remit state sales tax for products sold through a marketplace facilitator.

The Department has also issued Form DR 1290, Certification of Registered Marketplace Facilitator, which marketplace facilitators may use to certify that they are registered with the Colorado Department of Revenue and will collect and remit Colorado state and applicable taxes.

However, marketplace relief is transaction-specific. It generally does not cover:

• Direct website sales
• Enterprise sales outside the marketplace
• Sales through non-certifying platforms
• Historical exposure before facilitator collection began
• Local home rule obligations not handled by the marketplace
• Sales where the product is not treated as facilitated by the marketplace

A SaaS vendor selling through an app marketplace and also through its own website should split both channels. The marketplace may collect on app store sales, but the vendor may still need to register and collect on direct Colorado sales if it exceeds the threshold.

B2C and B2B treatment

Colorado sales and use tax is not limited to B2C transactions. It applies to taxable retail sales and taxable use. A business customer is not exempt merely because it is registered for sales tax.

Therefore, a remote SaaS or software provider may need to charge, collect, and remit Colorado sales tax on B2B transactions where:

• The customer is in Colorado
• The product or service is taxable
• The provider has nexus and collection responsibility
• The customer does not provide a valid exemption certificate, resale certificate, or other acceptable documentation
• The transaction is not exempt custom software or exempt software under a qualifying negotiable licence agreement

A Colorado sales tax registered business buying SaaS for its own internal use is normally the end user. If the SaaS is taxable and no exemption applies, the seller should collect tax if required. If the seller does not collect, the purchaser may owe use tax.

Use Tax Rules

If a taxable item or taxable service is purchased for use, storage, or consumption in Colorado and the seller does not collect tax, the purchaser generally owes consumer use tax. The Colorado Department of Revenue states that consumer use tax must be paid by Colorado businesses and individuals for purchases, and identifies Form DR 0252, Consumer Use Tax Return.

There is no general “small purchase” threshold that eliminates the purchaser’s underlying use tax liability. The threshold rules are mainly for seller collection obligations. For purchasers, the more relevant administrative rule concerns timing. 

That USD 300 rule is a filing timing rule, not a taxability exemption.

Colorado Sales and Use Tax Notice for Software Providers

Home rule cities

Colorado is more complex than many states because home rule cities may administer their own taxes and may have taxability rules that differ from the state. Denver already taxes software and SaaS under its local guide. Therefore, a provider cannot rely only on state-level guidance.

State rules are changing, but local rules may already be broader

The 2027 state change will bring Colorado state rules closer to some local rules. However, local tax bases, definitions, registrations, and filing requirements may still differ.

Negotiated licence agreements will need documentation

The new exemption for software under a negotiable licence agreement is likely to be a key audit issue. Standard online terms should not be assumed to qualify. Providers should retain signed agreements, redlines, correspondence, and evidence of actual negotiation.

Custom software must be truly custom

Labeling a product “custom” is not enough. If the provider sells a standard SaaS platform and merely configures settings, tax authorities may view the transaction as taxable prewritten software rather than exempt custom software.

Remote access and server location

Server location is unlikely to be the controlling factor. The more important question is whether the customer is using taxable software or digital goods in Colorado. Denver’s local guidance, for example, taxes SaaS where sale, storage, use, distribution, or consumption occurs in Denver, regardless of where servers are located, according to SALT commentary summarising the local approach.

Final Remarks

Colorado’s treatment of software and digital products is entering a major transition. Until December 31, 2026, SaaS and downloaded software may often remain outside Colorado state sales tax, although digital goods and some local home rule city rules, especially Denver, can already create tax exposure.

From January 1, 2027, HB26 1223 expands the state tax base to most software available for repeated sale or licence, including SaaS, remotely accessed software, mobile apps, and electronically delivered software, while preserving exemptions for custom software and qualifying negotiated licence agreements.

For local and foreign remote providers, the compliance message is clear: review Colorado sales volume, classify software and digital offerings, check customer locations, analyse home rule jurisdictions, prepare for 2027 taxability, and put registration, return filing, marketplace reconciliation, and exemption certificate processes in place before the effective date.
