An informational summary. It does not replace the official tender documents. Always confirm the deadline and the terms against the official ΚΗΜΔΗΣ record before submitting a bid.

Bid discount

Work out your bid and its discount on the budget excluding VAT (€205,298.75), and see where it sits among the discounts comparable tenders were awarded at.

The tender documents prevail. This is an indicative comparison with historical ΚΗΜΔΗΣ data, not legal advice.

Discount = 1 − bid ÷ the notice's budget excl. VAT, the same basis as the awards below. It is not the single discount rate of a works bid, which the tender documents apply to their own sub-total.

Clarifications

The statutory answer day for clarifications passed on 01/10/2026

The day by which the law requires the authority to answer, not a deadline for questions. The tender documents may set a stricter limit for submitting them — send your questions earlier.

The authority answers timely requests by 01/10/2026 — 6 days before the submission deadline (4 in an accelerated procedure: by 03/10/2026). άρθρο 67 §2–3 ν. 4412/2016

The tender documents are not stored here, so the limit for questions set by the tender notice was not read.

The tender notice prevails: check it for the limit on submitting questions.

An indicative calculation, not legal advice.

Calendar days; the deadline day itself is not counted. The statutory day is given as the law counts it, not moved when it falls on a Saturday, Sunday or public holiday.

Provisions checked on 30/09/2026.

Pre-litigation appeal

Appeal against the tender notice until 08/10/2026 άρθρο 361 §1Α ν. 4412/2016

Tender notice, published on ΚΗΜΔΗΣ 23/09/2026 · this pageuntil 08/10/2026

Each amendment of the tender notice opens its own 15-day deadline from its publication on ΚΗΜΔΗΣ.

Appeal fee €1,026.49 άρθρο 363 §1 ν. 4412/2016

Lot 1€979.24
Lot 2€600.00

For an appeal concerning only some lots, the fee is computed on their value. άρθρο 363 §2 ν. 4412/2016

The tender documents prevail. This is an indicative calculation, not legal advice.

Calendar days: the day of publication or notification does not count, and the deadline ends at the end of its last day. If that is a Saturday, a Sunday or a public holiday, it ends on the next working day. Local holidays and a moved 1 May holiday are not taken into account. ΑΚ 241 · ΑΕΠΠ 403/2018

Applies to contracts with an estimated value above €30,000.00 excluding VAT, other than direct awards. άρθρο 345 §1 ν. 4412/2016

The provisions were checked on 30/09/2026.

Net amount received

What a contract payment leaves once the contracting authority withholds the statutory deductions and income tax.

The tender documents and the paying authority decide. This is a calculation under the general rules, not tax or legal advice.

Net amount received	€196,889.71

The income tax was withheld under the general rule. The law puts this withholding on «φορείς γενικής κυβέρνησης εκτός από τις κεφαλαιουχικές εταιρείες» (general-government bodies other than capital companies): if the buyer is a capital company it is not made, and the net amount is €205,093.45. The record does not state the buyer's legal form; state it in the field above.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.

VAT is received on top and paid over, and is not included. The tax withheld is credited against the year's income tax (art. 64 §4 ΚΦΕ).

Rules for a payment on 06/10/2026 · sources checked on 30/09/2026

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.
