A Swedish aktiebolag (AB) selling into the United States trades one tax regime for dozens. At home, value-added tax (VAT) is a single national system: Skatteverket administers a 25% standard rate across the whole country. In the US, sales tax runs across 45 states, the District of Columbia, and thousands of local jurisdictions. Your obligation depends on where your customers are and how much you sell them, not where your business sits.
That shift started with one court case. In South Dakota v. Wayfair, Inc. (decided June 21, 2018), the US Supreme Court ruled that states can require out-of-state sellers to collect sales tax with no physical presence. For Swedish software, direct-to-consumer (D2C) e-commerce, industrial, furniture, and fashion exporters, US tax duties can now attach straight from Stockholm.
How Is US Sales Tax Different From Sweden’s VAT?
US sales tax is a state-level, single-stage tax added at checkout with no input credits. Swedish VAT is a national, multi-stage, reclaimable system run by Skatteverket at a 25% standard rate plus 12% and 6% reduced rates. The mental-model shift matters: Swedish firms habitually reclaim input VAT, but in the US you cannot reclaim tax you pay and only collect at the final sale.
| Feature | Sweden (VAT) | US sales tax | Source |
|---|---|---|---|
| Standard rate | 25% (reduced 12% and 6%) | Varies by state, 0%–10%+ | Skatteverket |
| Authority | Centralized (Skatteverket) | Decentralized (state and local) | Skatteverket |
| Collection stage | Every supply-chain stage | Final sale only | Skatteverket |
| Credit mechanism | Input VAT reclaimable | No reclaim on tax paid | Skatteverket |
| Price display | Included in listed price | Added separately at checkout | Skatteverket |
| Filing cadence | Uniform monthly or quarterly | Varies by state | State tax authorities |
Do Swedish Sellers Pay US Sales Tax?
Yes. Swedish sellers must collect US sales tax once they establish nexus with a state, and since South Dakota v. Wayfair (2018) no physical presence is required. Nexus attaches state by state through sales volume and customer location, not your Swedish address.
Four routes trigger it:
- Direct e-commerce above a state’s economic threshold.
- Marketplace sales through platforms like Amazon or Etsy.
- SaaS and digital products sold to US customers.
- Physical presence, such as inventory in a warehouse or staff on the ground.
What Creates Sales Tax Nexus for a Sweden-Based Business?
Nexus is the legal connection to a state that triggers a duty to collect sales tax, and it attaches state by state, not nationally. Four types create it, and a growing Swedish business can trigger several at once. Run an exposure check before you register, using Commenda’s US nexus guide.
- Physical nexus: inventory, warehouses, employees, or trade shows in a state.
- Economic nexus: crossing a state’s revenue or transaction threshold.
- Marketplace nexus: selling through a facilitator platform.
- Click-through nexus: paying US affiliates commissions for referrals.
What Are the Economic Nexus Thresholds by State?
Most states set economic nexus at $100,000 in sales. California, Texas, and New York use $500,000, and New York uniquely requires $500,000 AND more than 100 transactions. Transaction-count prongs are a shrinking feature: South Dakota repealed its 200-transaction prong effective July 1, 2023 under Senate Bill 30, and California, Texas, and New York never paired one with a pure dollar test.
| State | Dollar threshold | Transaction count | Measurement basis | Effective date | Source |
|---|---|---|---|---|---|
| Most states | $100,000 | Varies or none | Gross, retail, or taxable sales | N/A | State tax authorities |
| South Dakota | $100,000 | None (200-txn prong repealed) | Gross sales | July 1, 2023 | South Dakota SB 30 |
| California | $500,000 | None | Tangible personal property (TPP) delivered | April 1, 2019 | California Dept. of Tax and Fee Administration (CDTFA) |
| Texas | $500,000 | None | Total Texas revenue, rolling 12 months | October 1, 2019 | Texas Comptroller |
| New York | $500,000 AND >100 sales | More than 100 required | TPP over 4 sales tax quarters | $500k since June 24, 2019 | NY Dept. of Taxation and Finance |
| Tennessee | $100,000 | None | Retail sales, resale excluded | October 1, 2020 | Tennessee Dept. of Revenue |
The measurement basis matters for Swedish sellers with exempt B2B volume. In some states gross or retail sales count toward the threshold even when no tax is due, while others count only taxable sales. Thresholds are set in USD, so your SEK revenue tracking must convert on a fixed, documented methodology.

Which US States Have No Sales Tax?
Five states levy no statewide sales tax: New Hampshire, Oregon, Montana, Alaska, and Delaware, known together as the NOMAD states. A Swedish seller shipping only into these states owes no state sales tax there.
Alaska is only a partial exemption. It has no statewide tax, but its local governments levy sales tax, and remote sellers register and file through the Alaska Remote Seller Sales Tax Commission (ARSSTC). If your Alaska customers sit in a participating borough or city, you still collect at the local rate.
Do Marketplace Facilitator Laws Cover Swedish Sellers?
Yes. In every US sales-tax state, marketplace facilitator laws require the platform (Amazon, Etsy, eBay, Walmart) to collect and remit sales tax on the seller’s behalf. If you sell only through a marketplace, the platform generally handles the tax on those sales.
The traps are real. Some states still require you to register even when the marketplace remits. In many states, marketplace sales count toward your own economic nexus threshold for direct sales. If you run both a marketplace channel and a direct Shopify or own-site channel, you face the most complex position and must track both streams separately.
How Does a Swedish Company Get an EIN?
Most Swedish companies cannot get their Employer Identification Number (EIN) through the IRS online tool, because it requires a responsible party with a US Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). Instead, you apply using IRS Form SS-4 by fax or mail, or call the IRS International EIN line at +1-267-941-1099 (not toll-free, staffed during US business hours).
How Do You Register for US Sales Tax From Sweden?
Register state by state through each Department of Revenue (DOR) portal, or across multiple member states at once through the Streamlined Sales Tax (SST) registration system, which covers 24 member states. Processing typically takes several business days to a few weeks, and international verification can extend it. The big non-member states, including California, Texas, and New York, must be handled separately.
You need this documentation, made Sweden-specific:
- Bolagsverket registration certificate and your organisationsnummer.
- Your EIN.
- A US bank account or international wire arrangement for remittance.
- A registered agent for a US mailing address.
- Business and product descriptions.
Registration brings ongoing obligations: your sales tax permit per state, collection configuration, a filing calendar, rate updates, and audit-ready records for any future sales tax audit.
How Do You Collect and Remit US Sales Tax as a Swedish Seller?
Unlike VAT-inclusive Swedish pricing, US sales tax is added as a separate line at checkout, and the rate depends on the customer’s exact location: state, plus county, plus municipality. You collect at that combined rate, then remit to each state through its own portal, and many states mandate electronic payment.
A calculation engine keeps rates current by customer location across jurisdictions. SEK-to-USD conversion between the sale date and the remittance date creates timing exposure, so apply one consistent conversion methodology. Look up any rate with Commenda’s sales tax calculator.
How Do You File US Sales Tax Returns From Sweden?
Each state assigns your filing frequency (monthly, quarterly, or annual) based on your tax liability, and moves you to more frequent filing as volume grows. Most state deadlines fall on the 20th of the month after the period ends. Frequencies vary by state, so there is no single national schedule, and the state sets yours at registration.
Stockholm is 6 to 9 hours ahead of US time zones, which makes deadline scheduling a real operational issue. Common filing errors carry real cost: inconsistent SEK/USD conversion, mismanaged B2B exemption certificates, and misapplied product taxability across states.
Is SaaS Taxable in the US? State Rules for Swedish Software Companies
It depends on the state. Some tax software as a service (SaaS) fully, some partially, and some exempt it entirely, so a Swedish SaaS company must map taxability state by state. Texas taxes SaaS as a data processing service, while California exempts it. Many Swedish software sellers wrongly assume software is never taxed.
| State | SaaS taxable? | Notes | Source |
|---|---|---|---|
| Texas | Yes (partial) | Taxed as a data processing service; 80% of the charge taxable | Texas Comptroller |
| New York | Yes | Taxed as prewritten software | NY Dept. of Taxation and Finance |
| Washington | Yes | Taxed as a digital automated service | Washington Dept. of Revenue |
| Tennessee | Yes | Remotely accessed software taxable | Tennessee Dept. of Revenue |
| California | No | SaaS generally not taxable | CDTFA |
| Florida | No | SaaS generally not taxable | Florida Dept. of Revenue |
Cloud-delivered and downloadable software can be taxed differently in the same state. Bundled software plus services may need allocation. Customer-location sourcing is hard when users log in from multiple states, and USD threshold tracking against SEK pricing applies here too.
