A Slovak VAT invoice is governed by Act No. 222/2004 Coll. on VAT. It needs the supplier's name or business name, address, and VAT identification number, plus the recipient's name or business name, address, and VAT identification number where the supply was made under that number. Add the sequential invoice number, issue date, and the supply or payment receipt date when it differs from the issue date.
The line items need enough detail to show the quantity and type of goods or the scope and type of service. Include the taxable base for each VAT rate, unit price excluding VAT, discounts or rebates not already included, the VAT rate or exemption, and the total VAT payable in euros. A registered VAT payer generally issues the VAT invoice within 15 days from the supply, advance payment, or relevant month-end event.
Slovakia's indirect tax is value added tax, called daň z pridanej hodnoty or DPH. The 2026 VAT Act sets a 23% standard rate and reduced rates of 19% and 5% for listed goods and services. VAT registration controls whether the supplier charges VAT, so the invoice should match the supplier's VAT status and the specific supply.
A Slovakia-established taxable person becomes a VAT payer from the first day of the next calendar year after taxable turnover exceeds €50,000 in the previous calendar year, or from the supply that causes current-year turnover to exceed €62,500. VAT-exempt supplies need the Slovak VAT Act or EU VAT Directive provision, or a statement that the supply is exempt. Reverse-charge invoices must state prenesenie daňovej povinnosti.
Slovakia has a B2G e-invoicing mandate for public procurement, and public authorities must accept EN 16931-compliant e-invoices. B2B and B2C e-invoicing are not currently mandatory. Domestic B2B e-invoicing and real-time reporting are planned from 1 January 2027, with intra-EU reporting from 1 July 2030.
Language also matters after the invoice is sent. If an invoice is issued or received in a foreign language, the VAT payer or taxable person must provide a Slovak translation when the tax office requests it for inspection. Payment terms should be explicit. For EU commercial transactions with no agreed period, late-payment interest becomes payable 30 calendar days after invoice receipt.
A one-off invoice tool is enough when you need a single Slovak invoice, know the correct DPH treatment, and can store the final document with your tax records. It also works for occasional billing where every line item, VAT rate, exemption note, and payment term can be reviewed manually before sending.
A managed workflow becomes necessary when billable time, expenses, client defaults, discounts, and invoice status need to stay connected. Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, calculates amounts from rates, excludes non-billable work, and exports invoices to QuickBooks Online, Xero, or FreshBooks while keeping invoice status visible in Everhour.

A Slovak invoice can show DPH/VAT at the 23% standard rate or the 19% and 5% reduced rates for listed goods and services under the 2026 VAT Act. The correct rate follows the supply, not the customer's preference. Separate taxable bases by VAT rate so the invoice shows the taxable base and VAT amount clearly.
A Slovak VAT invoice must show the supplier's VAT identification number. It must also show the recipient's VAT identification number where the supply was made under that number. Buyer identity still needs the name or business name and address, even when the buyer's VAT ID is not applicable.
An invoice can be issued or received in a foreign language, but the VAT payer or taxable person must provide a Slovak translation when the tax office requests it for inspection. Keep the original invoice and make sure tax labels, exemption wording, and reverse-charge wording remain clear enough to support the VAT treatment.
B2B and B2C e-invoicing are not currently mandatory in Slovakia. B2G e-invoicing applies to public procurement, and public authorities must accept EN 16931-compliant e-invoices. Domestic B2B e-invoicing and real-time reporting are planned from 1 January 2027, so billing systems should be prepared for that change.
For EU commercial transactions, if the contract sets no payment period, late-payment interest becomes payable 30 calendar days after invoice receipt. Slovakia's statutory late-payment rate for 1 January-30 June 2026 is 10.15%, with a €40 flat recovery-cost compensation per late invoice.
Everhour Billing & Invoicing turns tracked billable time and expenses into invoices, calculates invoice amounts from rates, and excludes non-billable tasks. Client records can hold taxes, discounts, payment terms, and contact details that become invoice defaults before export to QuickBooks Online, Xero, or FreshBooks.
Everhour marks time as invoiced after it is included in an invoice, so the same billable work does not appear again in future invoices. Invoice status, number, issue date, and amount sync back from connected accounting tools for connected billing reports.
Turn approved billable work into client invoices with Everhour Billing & Invoicing. Keep rates, non-billable exclusions, invoice status, and accounting export connected to the same billing workflow.
