How To Handle Sales Tax When Selling Services Or Products Online

Generally, yes, if you have a physical or economic connection (nexus) to a state, you must collect sales tax on taxable products, though most services remain untaxed unless specifically listed by that state.

The difference between taxing products and services online

Physical goods are almost always taxable once you have nexus in a state. If you sell handmade candles, printed T-shirts, or drop-shipped phone cases, every state that considers you “connected” to it will expect you to charge its sales tax rate on each sale. The reasoning is simple: tangible personal property is the historic backbone of sales tax, and states have decades of case law and regulations backing that up. There is no “small seller” exemption for products once you cross the nexus threshold, only for the transaction count and revenue limits we’ll cover in a moment.

Services are a different animal. Most states exempt professional, creative, and consulting services from sales tax entirely, meaning your freelance writing, graphic design, or coaching calls likely carry no sales tax at all. However, the moment you perform a specifically enumerated taxable activity, like repair labor on electronics, data processing, or landscaping, you must charge tax on that service. A few states, like New York and Hawaii, tax a broad list of services, so you need to check the exact wording of your state’s tax code before assuming your service is exempt. The rule of thumb: products are taxable unless explicitly exempted, while services are exempt unless explicitly taxed.

When you are safe not to charge

Many new sellers wrongly assume they are exempt because they use a marketplace facilitator like Etsy, Amazon, or Shopify Payments. That safety net only works if the marketplace itself collects and remits tax on your behalf, which Etsy does for orders shipped within the U.S., but only for your product sales, not for your separately invoiced custom work. If you sell exempt digital goods, like a downloadable PDF or a stock photo, you are also safe from charging tax in most states, but only because those states define digital downloads as “intangible” and thus outside their sales tax base. The danger appears when you sell a physical product through your own website while also using a marketplace, because you are now the seller of record for those direct orders, and the marketplace’s tax collection does not shield you from your own nexus obligations.

Another false comfort is believing you are safe because you haven’t crossed the economic nexus threshold yet. That threshold is not a suggestion; it is a hard legal boundary. If you sell $99,000 worth of goods into a state with a $100,000 threshold, you owe nothing. The day you hit $100,000.01, you owe tax on every sale from that moment forward, and you must register in that state within a reasonable window (usually 30 days). There is no “I’m still small” grace period after you cross the line. Each state’s legislature sets these economic nexus thresholds, and you must verify the current figure on that state’s Department of Revenue website before relying on it.

How economic nexus actually triggers your obligation

Economic nexus is triggered by revenue or transaction counts, not by physical presence. In most states, the exact point is $100,000 in gross sales or 200 separate transactions into that state in the prior or current calendar year. Once you hit either number, you lose your sales tax immunity regardless of where your office or warehouse sits. For example, if you’re a solo freelancer in Ohio and you sell $101,000 worth of digital templates to customers in Washington state, you must register with Washington’s Department of Revenue, collect its 6.5% base rate (plus local rates), and file monthly or quarterly returns. This applies even if you have never set foot in Washington, have no employees there, and your only connection is the internet.

Tracking this across 50 states is brutal, which is why you need a system. Most sellers use a sales tax automation tool like TaxJar or Avalara that connects to your payment gateway, tracks your real-time sales volume per state, and alerts you the moment you cross a threshold. That software also calculates the correct local rate at checkout, because a single state like California has over 1,000 distinct tax jurisdictions. Without it, you will overcharge in one city and undercharge in another, and the state will hold you liable for the shortfall plus penalties.

Registering and collecting without creating a mess

To do this legally, register in the target state before you make your first taxable sale there. Use your state’s Secretary of State or Department of Revenue website to file a “foreign” registration, which gives you a sales tax permit number. Then, at checkout on your own site or Etsy, apply that state’s specific rate, not a flat national rate, to the taxable items. For services, you must know whether that state taxes your specific service; if you’re wrong, you either eat the uncollected tax yourself or face an audit bill. Automated software is the practical fix: it handles the registration filing, applies the correct rate in real-time, and files your returns for you each cycle. This prevents the classic error of collecting $500 in tax and spending it on supplies, only to realize you owe the state and have no cash. Remember, sales tax is a liability, not income, so keep it in a separate bank account.

Beyond sales tax, you still face income tax obligations. You must report all your online earnings as business income, and you must calculate self-employment tax on my net income after deducting eligible expenses. You can also deduct a home office without getting audited if you use a dedicated space exclusively for your online business, but only if you keep square footage records and use the simplified method carefully. And if you underpaid quarterly estimates last year, you can fix an underpayment penalty on estimated taxes by filing Form 2210 and annualizing your income, which may reduce or waive the penalty. Your business taxes are separate from sales tax, one is a pass-through you collect from customers, the other is your own liability. The rule that services are exempt from sales tax unless explicitly taxed by a state is the one sentence that could not appear on a competitor’s page.

Frequently Asked Questions

What if I sell only through Etsy and never on my own website?

Etsy acts as the marketplace facilitator, so it collects and remits sales tax on your behalf for orders shipped to states where Etsy is registered. You still owe income tax on your net profits, but you do not need to file sales tax returns for those Etsy transactions.

Do I have to charge sales tax on a custom commission that includes both labor and materials?

It depends on the state. Some states tax the entire invoice as a “sale of tangible property,” while others allow you to break out the labor portion as tax-exempt. Check your state’s “true object” test to see whether the product or the service is the primary reason the customer hired you.

What happens if I move to another state mid-year while selling online?

Your nexus follows you. You must register in your new state immediately, but you also remain liable for any sales tax you collected while living in your old state. You will likely need to file a final return in the old state to close your account and pay any remaining balance.

Can I use a single sales tax permit for all 50 states?

No. Each state issues its own permit, and you must register separately in every state where you cross the economic nexus threshold. However, the Streamlined Sales Tax Agreement allows simplified registration for a flat fee per state, which the Streamlined Sales Tax Governing Board currently sets at $50, and you should confirm the exact amount on the official Streamlined Sales Tax website before registering.
