Tax and invoicing in Cyprus
What applies to invoices in Cyprus, in short. As of October 2026.
- VAT
- Rates 19 %, 9 %, 5 % and 3 %, plus 0 % until 31 December 2026 for infant milk, nappies, hygiene products and fresh fruit and vegetables.

- The threshold is €15,600 of taxable turnover over 12 months, or expected within the next 30 days. If you sell services to businesses in other EU countries, you generally register from the first sale. Until you are registered, Saldiqo leaves VAT off and adds up your turnover.
