A valid Swedish invoice must include the seller’s value-added tax (VAT) number, sequential invoice number, description of the goods or services supplied, applicable VAT rate and amount, and total payable inclusive of VAT. These are all required under the VAT Act and Bookkeeping Act. Getting any of those wrong could result in rejected VAT deductions, bookkeeping corrections, or a customer who can’t close out their own accounts.

Below, we’ll explain every required invoice field, common mistakes, and how invoicing software manages compliance requirements automatically.

Highlights

• Swedish invoices must include specific VAT details, sequential invoice number, and clear description of goods or services.

• Cross-border invoices to EU businesses require the buyer’s VAT number and reverse charge reference, while exports outside the EU must reflect zero-rated VAT.

• Invoicing software can automate the structural requirements, but the accuracy of the underlying data remains the business’s responsibility.

What must an invoice include in Sweden?

Swedish invoice requirements aren’t complicated, but they are precise.

A VAT-registered business must include the following:

• Invoice date

• Invoice number

• Seller’s full name, address, and VAT registration number

• Buyer’s full name and address, and VAT registration number (if the buyer is liable for VAT on delivery or if it is an exempt Intra-Union sale of goods)

• Quantity, scope, and nature of the goods or services

• Date of delivery or performance of services

• Applicable VAT rate(s)

• Taxable amount for each tax rate

• Amount of VAT owed

• Total amount payable. This must also be stated in Swedish kronor (SEK) if invoicing in a foreign currency, or in euros if the accounting currency is euros.

A due date isn’t mandatory, but without one, you can’t enforce late payment interest.

Sweden also allows simplified invoices for transactions under 4,000 SEK, including VAT. A simplified invoice can omit the buyer’s details and per-rate breakdown, but still needs the date of issue, seller identity, description of the goods or services, and VAT amount owed or the applicable rate. Receipts from card terminals generally qualify.

What do Swedish bookkeeping and VAT laws require for invoices?

Beyond the list of details that need to be included on an invoice, the Bookkeeping Act and VAT Act specify a few other requirements businesses should be aware of.

Here’s what to know:

• Invoice retention: Every invoice (issued or received) must be retained for seven years from the end of the fiscal year in which it was created. The invoice serves as the supporting document that proves a transaction occurred.

• VAT-exempt supplies: If what you’re selling is exempt, note the exemption basis explicitly. Referencing the specific provision of the VAT Act that applies (e.g., “exempt under chapter 3, section 9 of the VAT Act”) is better practice than writing “VAT-exempt” without elaborating.

• Self-billing: Sweden permits the buyer to issue an invoice on the seller’s behalf, but only under a prior written agreement between both parties, and the invoice must be clearly marked as self-billed.

• Credit notes: When you correct or cancel an invoice, you issue an amending invoice, commonly called a credit note. It must reference the original invoice, clearly state what’s being changed, and carry the same identifying details as a standard invoice.

What must a Swedish invoice include for international trade?

Cross-border invoicing introduces additional requirements, and getting the invoices wrong can create customs delays, rejected VAT deductions, or unexpected tax liabilities.

Here’s how to get it right:

• EU B2B sales: When you sell goods or services to a VAT-registered business in another EU country, you don’t charge Swedish VAT. The buyer accounts for it under the reverse charge mechanism. Your invoice must include the buyer’s VAT number (verify it before issuing), state that the reverse charge applies (often written as “omvänd betalningsskyldighet” in Swedish), and show 0% VAT.

• Exports outside the EU: Goods exported to non-EU countries are generally zero-rated. The invoice should reflect 0% VAT and indicate the supply is an export. You’ll need to retain export documentation to support the zero rating if you’re audited.

• Services to non-EU customers: B2B services supplied to businesses outside the EU are typically outside the scope of Swedish VAT entirely. The invoice should show that no VAT applies.

• Currency: There’s no legal requirement to invoice in SEK for international transactions, but Swedish VAT amounts must be shown in SEK. Include the exchange rate and its source if you’re invoicing in another currency.

How do you create compliant invoices?

Invoice errors typically fall into a handful of categories. The consequences range from minor (e.g., payment delay) to material (e.g., rejected VAT deduction or VAT audit).

Here are some common mistakes:

• Missing or incorrect VAT registration number: Without your VAT number on the invoice, the recipient can’t reclaim input VAT. Check that your number appears on every invoice you issue.

• Nonsequential invoice numbering: Swedish tax authorities expect invoice numbers to follow an unbroken sequence. Make sure numbers aren’t accidentally being skipped.

• Vague service descriptions: The description needs to identify what was actually done. “Strategic communications consulting, 12 hours, related to product launch campaign” is the right level of detail. A third party reading the invoice should be able to understand the nature of the transaction.

• Wrong VAT rate: Sweden has three rates—25%, 12%, and 6%. Applying 25% to something that qualifies for 12% overcharges your customer and creates a correction to process later.

• Missing reverse charge reference on EU invoices: EU B2B invoices without the buyer’s VAT number or the reverse charge reference look like domestic invoices with no VAT. The buyer in another member state needs that reference to account for the tax correctly.

• Credit notes that don’t reference the original invoice: A credit note with no link to the original invoice number is nearly useless for bookkeeping purposes on both sides.
