E-Invoicing (FATOORA) in Saudi Arabia: Phase 2, Waves and the Rules

The short answer

Every VAT-registered business resident in the Kingdom must issue its tax invoices and credit/debit notes electronically. In Phase 2, B2B tax invoices are cleared by ZATCA before they reach the buyer and B2C simplified invoices are reported within 24 hours. Wave 25 covers taxpayers whose VAT-subject revenue exceeded SAR 187,500 in 2022, 2023, 2024 or 2025: they must integrate by 1 February 2027, once ZATCA notifies them.

Who and what is in scope

  • Every taxable person resident in the Kingdom, and any customer or third party issuing a tax invoice on its behalf.

    Source:E-Invoicing Regulation Art. 3(A)-(B), p.3 [T02-0200]
  • In scope: standard and zero-rated supplies, exports, intra-GCC supplies, deemed supplies and advance payments. Credit and debit notes wherever the VAT regulations require them.

    Source:ZATCA Resolution 62738 Clause First(5)-(6), pp.1-2 [T02-0207]
  • Out of scope: fully exempt supplies, reverse-charge supplies and imports of goods.

    Source:ZATCA Resolution 62738 Clause First(7), p.2 [T02-0208]

How Phase 2 works

  • Clearance (B2B): the invoice goes to ZATCA first; ZATCA checks it, stamps compliant invoices, and only then is it shared with the buyer.

    Source:ZATCA Resolution 62738 Clause Second(3)(A), pp.2-3 [T02-0211]
  • Reporting (B2C): the business stamps the simplified invoice itself and reports it to ZATCA within 24 hours; the customer can receive it at once.

    Source:ZATCA Resolution 62738 Clause Second(3)(B), p.3 [T02-0212]
  • Each invoice carries a UUID and a hash of the previous invoice, forming a chain that shows any deletion; a tamper-resistant counter cannot be reset.

    Source:ZATCA Resolution 62738 Clause Third(2)(C)(3),(5),(7), pp.4-5 [T02-0215]
  • A QR code is mandatory on all Phase 2 invoices and notes, adding the XML hash and the ECDSA signature and key to the Phase 1 fields.

    Source:ZATCA Resolution 62738 Annex 1 pp.12-13 [T02-0217]
  • Invoice solutions must not allow anonymous access, editing or deleting issued invoices, resetting the counter, or (from Phase 2) exporting the stamping key or changing the time.

Invoice content and corrections

  • A B2B e-invoice shows “Tax Invoice”, a sequential number, issue date and time, seller and buyer details and VAT numbers; Phase 2 adds UUID, previous hash, QR, counter and a seller ID such as the branch CR.

  • Where a B2B buyer is not VAT-registered, Phase 2 needs another buyer ID (CR, national ID and similar). Export invoices need neither.

  • A simplified invoice may be used for a B2B sale only below SAR 1,000.

    Source:Detailed Guideline v2 s.4.2.1(b), p.17 [T02-0227]
  • Every credit or debit note references the original invoice number(s); one note may cover a range of invoices.

    Source:Detailed Guideline v2 s.4.3, p.19 [T02-0230]
  • Visible invoice data must be in Arabic; other languages may be added.

    Source:Detailed Guideline v2 s.6.6, p.36 [T02-0232]
  • Self-billing and third-party billing need ZATCA’s prior approval and their own transaction flags.

Frequently asked questions

Who must issue electronic invoices?

Every taxable person resident in the Kingdom, and anyone issuing a tax invoice on its behalf, issues all tax invoices and credit/debit notes electronically. Non-residents are outside the obligation for their own supplies.

What is the difference between clearance and reporting?

B2B tax invoices are cleared: ZATCA checks and stamps them before they go to the buyer. B2C simplified invoices are reported: the business stamps them and reports them to ZATCA within 24 hours.

Does Wave 25 apply to us?

Wave 25 covers taxpayers whose VAT-subject revenue exceeded SAR 187,500 in 2022, 2023, 2024 or 2025. They must integrate by 1 February 2027, once ZATCA notifies them. Wave 24 (above SAR 375,000, deadline 30 June 2026) has passed.

How much notice does ZATCA give?

ZATCA selects each Phase 2 target group and notifies it at least 6 months before its due date. Taxpayers integrate by API according to their wave.

Source:ZATCA Resolution 62738 Clause Sixth(1)-(2), p.6 [T02-0223]
Can we cancel an e-invoice?

No. An issued e-invoice can never be edited, cancelled or deleted. Issue a credit note referencing it and, if needed, a new invoice. If ZATCA rejects a B2B invoice at clearance, fix it and submit a new document with its own counter and hash.

Source:Detailed Guideline v2 s.6.5, p.34 [T02-0229]
Is a PDF invoice enough?

Not on its own. Phase 2 invoices are generated in XML, or PDF/A-3 with the XML embedded, and only XML is transmitted to ZATCA. A scanned or photographed paper invoice is not an electronic invoice.

Source:ZATCA Resolution 62738 Clause Second(2), p.2 [T02-0210]E-Invoicing Regulation Art. 1(1)-(2), p.2 [T02-0202]
Do exports need an e-invoice?

Yes. Exports are zero-rated but still need a full e-tax invoice, cleared in Phase 2. The foreign buyer’s VAT number and additional ID are not required, and the export flag is set.

Source:ZATCA Resolution 62738 Clause First(5)(B), p.1 [T02-0242]
How long must e-invoices be kept?

At least 6 years, in the Kingdom, under the VAT record rules. The solution must allow offline archiving and export to an external archive.

Source:ZATCA Resolution 62738 Clause Fifth, p.6 [T02-0221]VAT IR Art. 66(1), (2) and (3) [T02-0013]
What penalties apply to e-invoicing breaches?

Breaches of the E-Invoicing Regulation and its Resolution are penalised under the VAT Law, by the violation classifications set by ZATCA Board resolutions.

Source:ZATCA Resolution 62738 Clause Eighth(2), p.8 [T02-0225]
Do simplified invoices have to be printed?

Simplified (B2C) invoices are given to the customer as a printed copy, unless the parties agree to share them electronically. B2B tax invoices must be shared electronically.
