Basis of calculation

Deductions are computed on the amount excluding VAT. Withholding on goods, fuels and services is computed on the amount after the deductions; on works and on an individual's fees, on the amount excluding VAT. The tender documents may set further deductions, depending on the buyer and the funding.

No tax is withheld when the payment is for electricity, telephone calls, telegrams, stamps, town gas (φωταέριο), water or tickets (case ββ), nor on a purchase of up to €150 without a contract (case αα) or from the suppliers of case δδ. The record is read as such only when every one of its CPV codes is one of these items; otherwise you set it under type of contract.ν. 4172/2013 (ΚΦΕ), άρθρο 64 §2 εδ. β΄ περ. ββ΄ · 03/10/2026

The withholding on goods, fuels and services is owed by «φορείς γενικής κυβέρνησης εκτός από τις κεφαλαιουχικές εταιρείες» (general-government bodies other than capital companies). No record states the buyer's legal form, so you state it; the category the registry states for the buyer can only suggest the answer «No».ν. 4172/2013 (ΚΦΕ), άρθρο 64 §2 εδ. α΄ · 04/10/2026Codified text as read on www.taxheaven.gr; not read at an official source.
