How US sales tax on digital products works: nexus and taxability

The United States has no national sales tax. States and, in many cases, counties and cities impose it, and the seller collects it from the buyer and remits it. That structure comes from state law.

The background on how it works is set out in Sales taxes in the United States - Wikipedia.

For a digital seller, two questions decide everything. First, do you have nexus in the state? Second, does that state treat your product as taxable? If the answer to either is no, you generally do not collect there.

Nexus: physical and economic

Physical nexus is the old rule. An office, an employee, a warehouse or a contractor in a state creates it. For digital sellers with no property or staff, physical nexus is rare.

Economic nexus is the rule that matters now. After the 2018 South Dakota v. Wayfair decision, states may require collection from remote sellers who cross a threshold of sales or transactions into the state.

Thresholds vary widely. Some states use a dollar figure alone, some use transactions alone, and some require both. A common pattern is $100,000 in sales or 200 transactions, but states such as Texas, New York and Washington set their own numbers and measurement periods.

Once you cross a threshold, collection usually starts on the next sale, not retroactively, though a few states look back. Track cumulative sales by state from your first day, because the threshold can arrive mid-year.

Taxability: is a download a taxable good?

States classify digital products in different ways. Some treat a download as tangible personal property. Some create a separate category for digital goods. Some tax only prewritten software. Some exempt digital products entirely.

That classification decides your rate and your filing. A taxable ebook sold in one state may be exempt in another, and a live online course may be treated as a service rather than a good. This is why sellers need a state-by-state view rather than a single setting in their checkout.

If you are unsure whether your store should collect at all, start with the practical test in charge sales tax on digital products, which walks through the nexus and taxability questions in order.

The seller's obligation

Where you have nexus and the product is taxable, you must register with the state, collect the correct rate at checkout, file returns on the state's schedule and remit the tax. Registration and filing pages differ by state; New York's are a typical example at Sales and use tax.

Rates are not one number per state. Local and district taxes stack on top of the state rate, and they change. California publishes current district rates at California City & County Sales & Use Tax Rate Information, which is the kind of page a seller checks before setting the rate for a California buyer.

Destination sourcing

Most states with economic nexus use destination sourcing. You charge the rate at the buyer's address, not your own. That means a single sale can carry a combined state, county, city and special district rate. For digital sellers, the buyer's billing address is usually the sourcing point, though some states use the address where the product is received.

Destination sourcing is why a flat national rate is impossible. Your checkout needs address-level rate lookup, or a service that provides it.

What the Streamlined Sales Tax Governing Board does, and what it does not do

The Streamlined Sales Tax Governing Board is a multi-state body that writes uniform definitions and procedures for member states. Its purpose is to reduce the cost of compliance for sellers who operate in many states. Member states adopt the same definitions for terms such as "digital products" and the same rules for exemptions and returns.

What it does:

What it does not do:

The practical value is definitional and administrative. For sellers in many member states, the uniform definitions remove guesswork about whether a product is a "digital good" or a "service." For sellers mostly in non-member states, the board's rules help less, and each state's own guidance governs.

A seller with a large catalog should compare member-state definitions against the state's own statutes. Where the two differ, the state statute controls.

States that tax digital goods, states that do not, and the states still deciding

Treatment falls into three rough groups: states that tax most digital goods, states that exempt them, and states that tax only some categories or are still clarifying. The table below covers six states with clearly different rules, plus a note on the broader pattern.

States that generally do not tax digital goods, or exempt broad categories, include Oregon, Montana, New Hampshire and Delaware, which have no statewide sales tax at all. Alaska has no state sales tax, though some local jurisdictions do. Those states still matter for income tax and for marketplace rules.

States still deciding or applying narrow rules include those that tax only specified digital categories, such as prewritten software or digital audio, while leaving ebooks or online courses outside the tax base. Some states have issued guidance rather than statute, so the position can change with a new ruling.

Because of that movement, a one-time map is not enough. Check the current position for each state where you cross a threshold, and use a state-by-state reference such as digital product sales tax by state to keep the list current.

IRS treatment of digital product revenue versus state sales tax on digital products

The IRS does not impose sales tax. It taxes income. Revenue from ebooks, courses, software licenses, memberships and downloads is ordinary business income, reported on Schedule C for a sole proprietor or on the business return for a corporation or partnership.

That income is reported whether or not the state sale was taxable. State sales tax is money you collect as an agent for the state, so it is not your income when properly collected and remitted. If you fail to remit it, the state treats the amount as a liability owed by you.

The IRS hub for business obligations, Businesses | Internal Revenue Service, covers the federal side: income tax, self-employment tax, estimated payments and employment tax if you have staff. None of that replaces state sales tax registration.

The SBA frames the same split for small online businesses in Manage your business - Small Business Administration, which is a reasonable starting checklist for a new digital store.

Other federal issues sit alongside tax. The FTC requires disclosure of affiliate relationships, which matters if you sell through partners or run an affiliate program. The U.S. Copyright Office governs protection of the content you sell.

The SEC has jurisdiction when a digital product looks like an investment. None of those change the sales tax analysis, but they change how you market and license the product.

Keep federal and state records separate. Your accounting system should show gross digital revenue, state sales tax collected, and tax remitted as three distinct lines.

Reading your own state department of revenue guidance without a tax adviser

State departments of revenue publish the rules that actually bind you. The pages are long and use statutory language, but a seller can extract the answer with a repeatable method.

A checklist you can reuse for each new state:

Two cautions. First, a call center answer is not binding; written guidance or statute is. Second, a state's general sales tax page may not mention digital goods at all, which is not the same as an exemption. Absence of guidance usually means the general rule applies.

If the product is bundled with a physical item or a service, the analysis gets harder. Many states tax the entire bundle unless the seller can show separate prices and separate delivery.

Marketplace facilitator laws and who collects when a platform sells for you

Marketplace facilitator laws require the platform to collect and remit sales tax on sales it facilitates. Every state with a sales tax now has one in some form. If you sell a course through a large platform, the platform usually collects from the buyer and remits to the state.

That does not remove your obligation in every case. The rules turn on who is the seller of record and whether the platform is a registered facilitator in that state.

Your own store remains your responsibility. When a buyer checks out on your site, you are the seller, and the marketplace rules do not apply. That is where rate lookup, registration and filing fall on you.

The fees a platform charges for hosting, delivery and payment are a separate cost line, and they vary by provider. A comparison of delivery platform fees helps you see the net after tax and fees.

If you sell through affiliates, the commission structure and the merchant-of-record question also affect who remits. Getting affiliate marketing for digital products right the first time covers the numbers sellers see in practice.

Keep a report of facilitated sales by state. Even when the platform collects, some states require the seller to file a zero or informational return, and the state may still count those sales toward your own nexus threshold.

A workable process for tracking sales tax on digital products across states

A small seller can run this without a tax adviser if the product catalog is simple and the state list is short. The process below is the one to follow when adding a state or a product.

A worked example. Suppose you sell a $49 ebook and a $199 online course from a home office in Oregon. Oregon has no sales tax, so your home state charges nothing. You sell into California, Texas and New York.

California: you cross $500,000 in combined sales late in the year. From the next sale, you collect California tax at the buyer's address, including district taxes. Texas: same $500,000 threshold, and you register and collect state and local tax, using the single local use tax rate if you qualify as a remote seller.

New York: you need both $500,000 in sales and more than 100 transactions in the prior four quarters, so a high-ticket course with few buyers may never cross it.

If the same course sells through a registered marketplace, the platform collects on those sales. Your direct sales still need your own registration and filing in California and Texas.

The system that supports this is the same one that supports checkout and conversion. Sellers often pick a stack for that reason, and a review of shopify vs woocommerce digital products is useful because the platform must pass the buyer's address to the tax calculation step. If it cannot, you calculate manually and carry the risk.

Finally, keep evidence. Save rate lookups, exemption certificates, platform reports and filed returns for at least the state's record retention period, which is often three to four years.
