Sweden Omvänd Skattskyldighet: Reverse Charge Moms Guide (2026)

Swedish VAT is called moms (mervärdesskatt), and its reverse charge mechanism is omvänd skattskyldighet — literally "reversed tax liability". If you invoice Swedish business customers, or receive invoices from Swedish suppliers, you need to know when the buyer (not the seller) accounts for the moms. This English-language guide covers the 2026 rules: the rates, the construction-sector byggmoms rules, and exactly what your invoice must say.

What omvänd skattskyldighet means

Normally the seller adds moms to the invoice and pays it to Skatteverket (the Swedish Tax Agency). Under omvänd skattskyldighet, the invoice is issued without moms, and the buyer reports both output and input moms on the same transaction in their momsdeklaration (VAT return). The mechanism is used for cross-border B2B trade within the EU and in fraud-sensitive domestic sectors — most notably construction.

The rules now sit in the current VAT act, Mervärdesskattelagen (2023:200), which replaced the 1994 act on 1 July 2023. Older guides referencing the old law's chapter numbers may be out of date, so always check references against the 2023:200 act.

Swedish moms rates in 2026

• 25% — standard rate, applies to most goods and services
• 12% — food, restaurant and catering services, hotel accommodation
• 6% — books, newspapers, passenger transport, cultural and sporting events

When a buyer self-assesses under reverse charge, they apply the rate that would have applied to a domestic sale — so knowing the correct rate category matters even though the seller charges nothing.

When reverse charge applies in Sweden

1. Intra-EU B2B supplies of goods

Goods sold by a Swedish business to a VAT-registered business in another EU country are invoiced at 0% with reverse charge. The buyer self-assesses moms in their own country. The legal basis is Article 196 of the EU VAT Directive, implemented in the Swedish act. The buyer's VAT number must be valid in VIES.

2. Intra-EU B2B supplies of services

Services supplied to a business customer established in another EU country are generally taxed where the customer is established — the Swedish supplier invoices without moms and the customer self-assesses. This is the most common reverse-charge scenario for consultants, agencies and SaaS companies.

3. Domestic construction: byggmoms

Sweden applies reverse charge domestically in the construction sector — byggmoms. When construction services are sold to a buyer who is themselves a taxable person supplying construction services (typically a main contractor buying from a subcontractor), the buyer accounts for the moms, not the subcontractor.

Practical points for byggmoms:

• The seller must verify that the buyer is a taxable person active in the construction sector — if the buyer is a private individual or a business outside construction, normal 25% moms applies.
• The invoice must state "Omvänd betalningsskyldighet" and include the buyer's VAT number.
• The buyer reports output moms on the purchase and simultaneously deducts it as input moms (assuming full deduction rights).

4. Other domestic reverse-charge goods

Reverse charge also applies domestically to certain high-fraud-risk goods, including scrap metal, mobile phones and integrated circuits above thresholds (notably electronics sales exceeding 100,000 SEK), and gas/electricity sold to resellers. If you trade in these categories, check the specific thresholds in the current act.

What your Swedish invoice must contain

A reverse-charge invoice in Sweden must include:

• The words "Omvänd betalningsskyldighet" — this exact phrase is required, not just "reverse charge" in English
• The buyer's VAT number in the format SE + 12 digits (e.g. SE556677889901)
• Net amounts with no moms added
• All standard invoice details: sequential number, dates, description of goods/services, both parties' names and addresses

One Sweden-specific rule: if any VAT amount is shown on the invoice (for example on a mixed invoice), it must be expressed in SEK. Foreign-currency invoices should show the moms equivalent in kronor.

What the buyer must do

The buyer reports the transaction in their momsdeklaration: output moms calculated at the applicable rate on the net amount, and — if they have deduction rights — the same amount as input moms. For a fully taxable business the two cancel out. Businesses with exempt activities or partial deduction must be careful: the output moms is a real cost to the extent they cannot deduct.

Common mistakes

• Charging 25% moms to an EU business customer. If the customer has a valid EU VAT number and the place-of-supply rules point to their country, charge 0% with reverse charge — not Swedish moms.
• Byggmoms to the wrong buyer. Selling construction services to a private homeowner or a non-construction business? Normal moms applies. Reverse charge is only for qualifying construction-sector buyers.
• Missing "Omvänd betalningsskyldighet". The Swedish phrase is mandatory. Without it (and without the buyer's VAT number), the buyer cannot properly self-assess, and the invoice is formally defective.
• Wrong VAT number format. Swedish VAT numbers are SE followed by 12 digits — not 9, not 10. Validate in VIES before invoicing.
• Using the old 1994 act's references. Since 1 July 2023 the applicable law is Mervärdesskattelagen (2023:200). Old chapter/section citations in templates should be updated.

Frequently asked questions

Does reverse charge apply to sales to Swedish consumers?

No. Omvänd skattskyldighet is a B2B mechanism. Sales to private individuals (consumers) always carry Swedish moms at the applicable rate, and byggmoms never applies to consumer jobs.

I am a foreign business selling services to a Swedish company. Do I charge moms?

Generally no — for B2B services the place of supply is Sweden (the customer's country), and the Swedish customer self-assesses under omvänd skattskyldighet. You invoice 0% with the reverse-charge wording and report the sale according to your own country's rules (e.g. EC Sales List).

What rate does the buyer use when self-assessing?

The rate that would apply to an equivalent domestic supply: 25% for most services, 12% for food-related services, 6% for books, passenger transport and cultural services.

Do I need to register for moms in Sweden to receive reverse-charge invoices?

To self-assess as a buyer you must be a taxable person registered for moms in Sweden (or registered for the specific transaction type). Non-established businesses should check whether they need a Swedish VAT registration or can use the reverse charge as the customer.

How does byggmoms differ from normal reverse charge?

Byggmoms is a domestic reverse charge: both parties are Swedish, but the construction-sector buyer accounts for the moms instead of the subcontractor. Cross-border reverse charge involves two different EU countries. Both require the "Omvänd betalningsskyldighet" invoice mention.
