Digital Product Sellers: $100K Economic Nexus Rules for Ebook, Course, and Downloadable Software Revenue

The Digital Goods Taxability Patchwork

Before you can determine what to collect, you need to understand what each state actually taxes. Digital products do not have a uniform federal definition. Each state decides independently whether ebooks, online courses, downloadable software, digital music, streaming content, and other electronically delivered goods are subject to sales tax.

The variation is significant. Pennsylvania taxes “canned software” and “digital goods” broadly — ebooks, downloaded music, and prewritten software all fall within the tax base. Florida taxes canned software delivered electronically but does not tax ebooks or digital audio/video content. Georgia generally does not tax digital goods that are not delivered on tangible media, though specific categories like canned software may still apply. North Carolina taxes most digital property including ebooks, digital audio, and software. Arizona applies its Transaction Privilege Tax to downloaded software and many digital goods under the Retail classification.

This matters for digital product sellers because you might sell the exact same ebook to customers in all five states and face five different tax treatments. The ebook might be taxable in Pennsylvania and North Carolina, exempt in Florida and Georgia, and subject to TPT in Arizona depending on how the state classifies it.

State-by-State: Digital Goods Taxable vs. Counts Toward Threshold

The following table summarizes how each Tier-A state treats common digital product categories for both taxability and nexus-threshold purposes.

Florida: Canned Software Downloads Are Taxable

Florida draws a sharp line between canned software and other digital products. Under Florida law, canned (prewritten) software delivered electronically is taxable. This includes downloadable apps, productivity tools, design software, and any pre-built software sold to multiple customers without substantial customization. If you sell a downloadable project management tool or a Photoshop plugin, Florida treats it as taxable tangible personal property.

However, Florida does not tax most other digital goods. Ebooks, digital audio, digital video, and online courses delivered electronically are generally not subject to Florida sales tax. This means an ebook seller shipping exclusively digital downloads to Florida customers would owe no sales tax on those transactions — but every dollar of that ebook revenue still counts toward Florida's $100K economic nexus threshold.

For sellers with blended product lines — say, an ebook plus a companion software tool — this creates a split obligation. Once you cross the $100K threshold and register, you collect tax on the software download but not on the ebook. Both products' revenue counted toward the threshold, but only the software generates a tax liability.

Georgia: Narrow Digital Goods Exclusions

Georgia's treatment of digital goods is narrower than many states. Georgia generally does not tax digital products that are delivered electronically without tangible media — meaning a downloaded ebook or streaming video course is typically not subject to Georgia sales tax. The state's sales tax base is built around tangible personal property, and purely electronic deliveries often fall outside that definition.

The exception is canned software. Georgia taxes prewritten computer software regardless of delivery method. A downloadable software application is taxable whether the customer receives it on a CD or downloads it from your website. This distinction matters for digital product sellers who offer both content (ebooks, courses) and tools (software, plugins, apps).

Georgia's economic nexus threshold is $100,000 in gross revenue or 200 transactions. All digital sales — taxable and exempt — count toward this threshold. A course creator selling $120K in online courses to Georgia customers would cross the nexus threshold and must register, even though none of those course sales may be taxable. After registration, the seller files returns showing the exempt sales and remits tax only on any taxable items (such as bundled software downloads).

North Carolina: Digital Products Broadly Taxable

North Carolina takes a broad approach to digital product taxation. The state taxes “digital property,” which includes audio works, audiovisual works, books (including ebooks), magazines, newspapers, newsletters, reports, photographs, and greeting cards delivered electronically. This definition captures most content products that digital sellers offer.

Canned software delivered electronically is also taxable in North Carolina. Whether you sell a downloadable design tool, a pre-built spreadsheet template, or a mobile app, North Carolina treats it as taxable.

Online courses fall into a gray area depending on delivery format. A pre-recorded course delivered as downloadable video files is more likely to be classified as taxable digital property. A live, interactive webinar or coaching session is more likely treated as a non-taxable service. The distinction hinges on whether the customer receives a “digital good” they can store and access repeatedly, or whether they are purchasing access to a live service.

North Carolina's threshold is $100,000 in gross revenue or 200 transactions. All revenue — from taxable ebooks, exempt services, and everything in between — counts toward the threshold. Digital sellers with significant North Carolina customer bases should monitor their NC-delivered revenue closely, because crossing the threshold in a state that broadly taxes digital goods means immediate collection obligations on most product lines.

Pennsylvania: Broad Digital Taxation

Pennsylvania is one of the most aggressive states when it comes to taxing digital products. The state taxes “canned software” delivered electronically, and it also taxes a broad category of “digital goods” that includes ebooks, digital audio (music, podcasts for purchase), digital video, digital photographs, and digital books. Pennsylvania's tax base for digital products is among the widest of the Tier-A states.

Online courses in Pennsylvania depend on the delivery mechanism. A downloadable course — pre-recorded videos, PDFs, and workbooks that the buyer downloads and keeps — is likely taxable as a digital good. A live streaming course or real-time webinar is more likely a non-taxable service. SaaS-delivered course platforms where the buyer accesses content through a browser without downloading files may be treated differently depending on the specific arrangement.

Pennsylvania uses a $100K revenue-only threshold with no transaction count alternative. All gross revenue delivered to Pennsylvania — taxable and exempt — counts toward the threshold. For digital product sellers, Pennsylvania is often the first state where the “registration cliff” becomes painful: you cross $100K, register, and immediately owe tax on nearly every digital product you sell because Pennsylvania taxes digital goods so broadly.

Arizona TPT: Digital Goods and the Retail Classification

Arizona's Transaction Privilege Tax applies to the privilege of doing business in Arizona, and the treatment of digital goods falls primarily under the Retail classification (A.R.S. § 42-5061). Downloaded software is generally taxable under TPT — it is treated as tangible personal property transferred electronically. Pre-built software tools, downloadable apps, and software plugins sold to Arizona customers are subject to TPT at the combined state and local rate.

Other digital products receive more nuanced treatment. Arizona has been evolving its position on digital goods, and the taxability of ebooks and digital content can depend on the specific format and delivery method. Online courses delivered as live instruction are generally treated as non-taxable services. Pre-recorded content delivered as downloads may fall under the Retail classification.

Arizona's economic nexus threshold is $100K in gross revenue from Arizona customers. All revenue — from TPT-taxable software downloads, potentially exempt digital content, and physical goods — counts toward this threshold. Once crossed, you must obtain a TPT license and begin collecting TPT on taxable transactions under the appropriate business classification.

The Registration Cliff: When Taxability and Nexus Collide

The “registration cliff” is the moment when two conditions become true simultaneously: you have nexus in a state (because you crossed the $100K threshold), and that state taxes the products you sell. Before you cross the threshold, you have no obligation — no registration, no collection, no filing. The day after you cross it, you owe registration, ongoing collection on every taxable transaction, and periodic return filing.

For digital product sellers, the cliff is especially steep in states with broad digital taxation. Consider a seller of downloadable design templates who crosses the $100K threshold in Pennsylvania. Before crossing, they collected zero tax from PA customers. After crossing, every template sale to a PA customer now requires tax collection at the 6% state rate (plus any applicable local tax). There is no gradual phase-in — the obligation is immediate and applies retroactively to the date the threshold was exceeded in many states.

The cliff is less severe in states where your specific product is exempt. Crossing the $100K threshold in Florida as an ebook-only seller still triggers registration, but since Florida does not tax ebooks, your collection obligation may be zero. You still must file returns — showing exempt sales — but you do not charge customers additional tax.

Tracking Blended Physical and Digital Revenue

Many digital product sellers also sell physical goods — printed books, merchandise, hardware accessories, or physical course materials. Blended revenue complicates nexus tracking because physical and digital products may have different taxability rules, but all revenue counts toward the same $100K threshold.

The best practice is to track revenue by state and by product category from the start — before you approach any threshold. Set up your e-commerce platform to tag each product as physical, taxable digital, or exempt digital. Then generate state-level reports that show total revenue (for threshold monitoring) and revenue by category (for collection configuration after registration).

For threshold monitoring across states, the number you care about is total gross revenue delivered to each state — physical plus digital, taxable plus exempt. Once you cross a state's threshold, switch to the detailed breakdown to configure which products require tax collection in that specific state.
