Tax Department — TAXISnet, Ariadni, VAT return

Everything tax-related in Cyprus goes through the Tax Department (Τμήμα Φορολογίας — the tax administration). To file online, you authenticate via Ariadni, the government's single sign-on gateway (the Cypriot equivalent of a national identity gateway), then access TAXISnet, the e-filing portal. This is where a company files its VAT return (in Greek ΦΠΑ) and obtains its payment reference.

History — the 2014 merger and digitisation

Until 2014, Cyprus separated direct tax (Inland Revenue) and VAT (VAT Service) into two distinct administrations. The 2013 banking crisis and the adjustment programme accelerated a deep reform: the merger into a single, more efficient and more digital Tax Department. TAXISnet, already in place for some returns, became the central electronic counter, and authentication was streamlined via the Ariadni gateway, shared with the other online public services.

Governance — Tax Department + DITS

The Tax Department holds the business responsibility (tax rules, forms, audit). The DITS (Department of Information Technology Services) provides the state's shared technical infrastructure, including Ariadni. This separation is classic: the tax authority decides "what" to file, government IT handles "how" to connect and secure access.

Schema — Ariadni → TAXISnet → ΦΠΑ return

The filing journey follows a simple chain: authentication via Ariadni, access to the TAXISnet VAT service, entry or import of the ΦΠΑ return, submission, then referenced payment.

TAXISnet vs neighbouring portals

Calendar, payment and obligations

• Period: VAT return in principle quarterly, with staggered calendars depending on the taxable-person group.
• Due date: filing and payment 40 days after the end of the VAT period.
• Payment: via JCCsmart (the Cypriot payment platform) or transfer, using the reference generated by TAXISnet.
• Other filings: intra-EU recapitulative statements (VIES) and Intrastat returns above thresholds.

Common pitfalls

• Believing TAXISnet transmits invoices. It is a filing portal; B2G e-invoicing goes over PEPPOL / Treasury.
• Inactive Ariadni account. Without a valid Ariadni identity, no access to TAXISnet — enrolment is a prerequisite.
• Missing the P + 40 deadline. Late filing or payment triggers penalties and interest.
• Forgetting VIES. Intra-EU supplies must be reported in the VIES recapitulative statement, separate from the ΦΠΑ return.
