Cyprus Invoice Requirements: What Every Invoice Must Show

One missing line on an invoice — the customer's VAT number, the words "Reverse charge", a per-rate VAT breakdown — can undo a zero-rating or resurface in an audit a year later. Cyprus invoice requirements are not one fixed list: a core set applies to every invoice, and the transaction adds the rest.

This guide covers the legal structure behind that — the invoicing rules of the EU VAT Directive (2006/112/EC), which apply in Cyprus as in every EU member state : core particulars, mandatory wording, deadlines, retention, simplified invoices. The aim: every required field, and a clean handoff to the accountant who files. One note up front: TaxItEasy is our product — where it appears below, we say so.

What must every Cyprus VAT invoice include?

Eleven core particulars form the every-invoice checklist EU-wide, Cyprus included: issue date, sequential number, both parties' names and addresses, the VAT numbers, a description of the supply, the supply date if it differs, per-rate net amounts, the VAT rate, the VAT amount, and an exemption reference where relevant.

The source is Article 226 of the EU VAT Directive, and it contains no flat list of "mandatory fields": 18 individual particulars in total, of which 11 form the core set relevant to every invoice and seven switch on only for specific transactions . The core set:

1. Date of issue
2. A sequential number uniquely identifying the invoice
3. Your VAT identification number
4. Your customer's VAT number — when they are liable for the VAT (reverse charge) or receive an intra-EU supply
5. Full name and address of both you and your customer
6. Quantity and nature of the goods, or extent and nature of the services
7. The supply date — where it differs from the issue date
8. The taxable amount per rate or exemption, unit price and any discounts
9. The VAT rate applied
10. The VAT amount payable
11. A reference to the exemption, where one applies

Even the core set flexes: several items apply only when triggered . Fixed field counts you see online compress this conditional structure into one list — and what drops out is usually a conditional item, like the differing supply date or the mandatory wording covered next.

When does your invoice need extra wording?

When the transaction itself changes the VAT treatment, the directive requires specific wording on the invoice. Bill an EU business customer who accounts for the VAT, and the invoice must carry the words "Reverse charge". Self-billing, cash accounting and margin schemes each trigger their own mandatory mention.

These are the transaction-dependent particulars of Article 226 :

• "Reverse charge" — mandatory in exactly those words whenever your customer is liable to account for the VAT (Article 226(11a)) ; the everyday case for Cyprus freelancers invoicing EU business clients.
• "Self-billing" — where your customer issues the invoice on your behalf .
• "Cash accounting" — where a cash-accounting scheme makes the VAT chargeable on payment .
• The relevant margin-scheme mention, details of a new means of transport, or tax-representative details — each in its specific case .

One distinction many guides blur: Article 196 decides who owes the VAT on a cross-border B2B service — your customer, under the reverse charge — while what the invoice must say comes from Article 226(11a) .

Standard practice before zero-rating a cross-border B2B supply: confirm the customer's VAT number in the EU's VIES database.

How does Cyprus invoice numbering work?

Every invoice needs a sequential number, from one or more series, that uniquely identifies it — Article 226(2) of the directive . In practice: an unbroken series, numbers issued in order, none skipped, none reused. A gap in the series invites questions in an audit.

The directive allows one or more series — a fresh series per year is common — but within each series the sequence must hold. The structural fix is numbering that lives in the system issuing the invoice, consumed only at finalize. TaxItEasy's invoicing works that way — year-scoped sequences, strict order, a built-in gap report ; mechanics in the invoice numbering help article.

When do you have to issue the invoice, and how long do you keep it?

It depends on where your customer is. For intra-EU B2B supplies under the reverse charge, EU law sets a hard deadline: the 15th day of the month after the month of supply. For domestic Cyprus sales, Cyprus sets its own cutoff — ask your accountant. Keep every invoice at least six years.

The cross-border rule is uniform EU-wide: for intra-EU supplies and for reverse-charge services to EU business customers, the invoice must be issued by the 15th day of the month following the month of supply (Article 222(1)) . Deliver in August; invoice by 15 September.

For purely domestic supplies, the directive leaves the deadline to each member state (Article 222(2)) . Cyprus sets its own domestic cutoff, and the figures circulating online aren't confirmed by a primary source we could verify — ask your accountant for the current rule.

Retention changed on 1 January 2026: Cyprus now requires books and records — invoices included — kept at least six years from the filing deadline or the actual filing date, whichever is later (law N. 243(I)/2025, Official Gazette No. 5070, 31 December 2025) . Older pages still cite seven or eight years; the enacted Gazette text says at least six .

Can you use a simplified invoice for small sales?

Yes, within limits EU law itself sets. Every member state, Cyprus included, must allow a simplified invoice with reduced content when the amount is €100 or less, and may raise that ceiling to €400. You may see €85 cited for Cyprus — that figure sits below the EU floor, so treat it with caution.

The floor is Article 220a: every member state must accept a simplified invoice up to €100, and may raise the ceiling to €400 (Article 238) . Cyprus's exact administrative threshold isn't confirmed against a primary source we could reach — and "€85" circulating online sits below the EU minimum, a reason to check with your accountant rather than repeat it .

The reduced content is fixed by Article 226b: issue date, identification of the supplier, the type of goods or services supplied, the VAT amount payable or the information to calculate it, and, for a document amending an earlier invoice, a reference to it and the changes . Member states may not demand more on a simplified invoice .

What happens if an invoice is missing a mandatory field?

Practical friction, mostly on your customer's side first. An invoice missing a required particular may not support the VAT treatment it claims: without the customer's VAT number, a reverse-charge invoice doesn't document why no VAT was charged; without a per-rate breakdown, your customer's input-VAT deduction rests on shaky paper.

The failure rarely shows at issue time: it surfaces when your customer's bookkeeper rejects the invoice, or when an auditor finds the words "Reverse charge" missing from a zero-VAT invoice a year later . Corrections — a credit note plus a corrected invoice — cost time and delay payment.

The cheaper option is catching the gap before the invoice leaves — a job software can do. TaxItEasy checks every required field is on the invoice before you can send it: pre-finalize validation refuses to issue an invoice with a required particular missing .

Is a PDF invoice legally valid in Cyprus?

Yes. EU VAT law treats an electronic invoice — a PDF sent by email included — as equivalent to paper, provided the recipient accepts it and you can ensure authenticity of origin, integrity of content and legibility. Ordinary business controls with an audit trail are enough; no electronic signature is required.

Article 232 makes electronic invoicing subject to the recipient's acceptance; Article 233 requires authenticity of origin, integrity of content and legibility until the end of the retention period — achievable through any business controls that create a reliable audit trail . An advanced electronic signature (based on a qualified certificate) or EDI is an example, not an obligation . The everyday setup — a PDF emailed to a willing customer, records kept on both sides — qualifies.

TaxItEasy sends invoices as PDFs by email straight from the editor, filed into your records at issue . Structured e-invoicing formats — a separate topic from PDF validity — are rolling out on country-specific timetables; our EU e-invoicing overview tracks them.

How this fits into your Cyprus VAT and bookkeeping workflow

A correct invoice is the first record in your VAT chain: its per-rate totals build your quarterly VAT position, and clean invoices now mean fewer questions at review time later.

The invoice is one station in a loop: invoices out, receipts in, the amounts feed a running VAT picture, your accountant reviews and files. The whole loop — VAT registration at €15,600 , the 19%, 9%, 5% and 3% rates , the 2026 reform — is covered in our Cyprus bookkeeping and accounting software guide.

Disclosure: TaxItEasy is our product, and this is the section about it. On the invoicing side: an editor that mirrors the final PDF — same layout, same totals, same number ; seven VAT treatments in one dropdown, each with the mandatory notice wording generated automatically ; customer VAT numbers checked against the EU's VIES register . Before anything goes out, TaxItEasy checks every required field is on the invoice before you can send it .

Then it stops, on purpose. The totals flow into your running VAT overview, and your accountant — not the software — reviews the quarter and files the return. To see it, create your first invoice on the free plan via the invoicing page — or take the freelancer tour first.

Frequently asked questions

What are the mandatory fields on a Cyprus VAT invoice?

There is no single fixed count. Article 226 of the EU VAT Directive names 11 core particulars potentially relevant to every invoice — dates, numbers, names, VAT IDs, amounts per rate — plus seven more that switch on for specific transactions, such as reverse charge or self-billing . Round numbers cited elsewhere are informal compilations.

What must a reverse-charge invoice say in Cyprus?

The words "Reverse charge", verbatim — required by Article 226(11a) of the EU VAT Directive whenever the customer is liable to account for the VAT . The invoice shows no Cyprus VAT and must carry the customer's VAT number , which identifies who will account for the tax instead.

Do I need to register for VAT before I can issue a Cyprus invoice with VAT on it?

Yes. An invoice can only show Cyprus VAT if you are VAT-registered, and registration becomes mandatory once taxable turnover passes €15,600 in the last 12 months . Below that line you can still invoice clients — just without a VAT line and without a Cyprus VAT number. Ask your accountant about your registration position.

What are Cyprus's VAT rates in 2026?

The standard rate is 19% , with reduced rates of 9% and 5% and a super-reduced 3% , per the European Commission's VAT rates table (last checked July 2026). Which goods and services fall under each reduced rate follows detailed category rules — confirm yours with your accountant before relying on it.

How long do I need to keep my Cyprus invoices?

At least six years from the filing deadline or the date you actually filed, whichever is later — the Cyprus rule since 1 January 2026, set by reform law N. 243(I)/2025 . Retention extends if an examination starts late in the period. Pages citing seven or eight years describe pre-2026 rules.

Does invoicing software file my Cyprus VAT return for me?

Some tools do; TaxItEasy deliberately does not. It prepares the invoice and the numbers behind it: required fields checked before you can finalize, VAT wording generated, gapless numbering, PDF sent by email . The VAT totals feed your quarterly figures; your accountant reviews and files the return.
