Saudi Arabia halved its e-invoicing threshold to catch $50,000-a-year businesses, and the UAE launches a completely different system in ten weeks
Saudi Arabia's e-invoicing net just widened to catch businesses with one good year since 2022, while the UAE's own mandate launches in ten weeks on a system that works nothing like Saudi Arabia's or Egypt's.
On July 24, 2026, Saudi Arabia's tax authority announced the 25th wave of its mandatory e-invoicing rollout, Wave 25, and the headline number is the threshold: SAR 187,500 in annual VAT-subject revenue, about $50,000 at the riyal's fixed peg. That's half of Wave 24's threshold from two months earlier, which was itself half of Wave 23's threshold the wave before that. The businesses ZATCA is pulling into mandatory e-invoicing now aren't mid-size companies. $50,000 a year is a single freelancer with a good client, a two-person consultancy, a small retail counter.
Ten weeks from today, a separate mandate starts in the UAE, built on a different kind of system entirely. Where Saudi Arabia and Egypt clear every invoice through one government-run portal, the UAE requires businesses to transact through a network of private, accredited intermediaries, with the tax authority receiving the underlying data on the side rather than approving the invoice directly.
Neither mandate waits for a business to notice it. This piece covers what each one actually requires, going by what each country's own published criteria say, not by whichever compliance vendor's blog post gets there first.
Saudi Arabia's tax authority, ZATCA, set Wave 25's threshold at SAR 187,500 in revenue subject to VAT, and the rule that catches businesses is a lookback: scope is decided by whichever of a business's fiscal years from 2022 through 2025 had the highest VAT-subject revenue, not by what it's earning this year [1][2]. A business that had one strong year in 2023 and has since scaled back is still in scope for Wave 25 even if its current revenue is a fraction of the threshold. ZATCA notifies the specific taxpayers it has identified at least six months before their integration date, which for Wave 25 falls on February 1, 2027 [2].
The pattern across the last three waves is the real story. Wave 23 set the bar at SAR 750,000 (about $200,000) with an integration deadline of March 31, 2026. Wave 24, announced roughly four months later, halved that to SAR 375,000 (about $100,000), due June 30, 2026. Wave 25 halved it again to SAR 187,500 (about $50,000), due February 1, 2027 [2][3]. Three waves, two halvings, under thirteen months. Whatever threshold convinced a business it was safe six months ago isn't the threshold ZATCA is using now.
The UAE's own mandate, confirmed by its Ministry of Finance during 2026, starts with the largest businesses: anyone with AED 50 million or more in annual revenue, about $13.6 million, must be live on mandatory e-invoicing by January 1, 2027 [4]. Smaller businesses get a longer runway: an Accredited Service Provider appointed by March 31, 2027, and go-live by July 1, 2027. Government entities follow on October 1, 2027 [7].
What makes the UAE mandate a different build, not just a later deadline, is the model underneath it. Saudi Arabia and Egypt both run centralized clearance: every invoice passes through one government portal, which validates it before it counts as issued. The UAE instead runs what its Ministry of Finance calls a Decentralized Continuous Transaction Control and Exchange, commonly described as a five-corner model, built on the Peppol network with a UAE-specific data standard called PINT AE [5]. An invoice goes to the seller's own Accredited Service Provider, which validates it against PINT AE and sends it over Peppol to the buyer's Accredited Service Provider, which passes it to the buyer. The underlying tax data reaches the Federal Tax Authority separately and after the fact, as a structured report, not as part of clearing the transaction itself [5].
Appointing an Accredited Service Provider doesn't hand off responsibility for getting it right. The ASP converts, transmits and reports the data, but the taxpayer stays accountable for the invoice's accuracy and its retention [5]. Accreditation itself is gated: a UAE Ministerial Decision requires an ASP to be a registered Peppol participant, incorporated in the UAE, technically capable of the PINT AE specification, and compliant with the UAE's data security standards [6]. That's a narrower pool of vendors than any software that can email a PDF, and it's worth confirming before assuming a current invoicing tool already qualifies, or has a path to.
A business trading in more than one of these three markets, which is common for MENA retailers and distributors, now carries two structurally different compliance paths at once: the single-portal clearance that Saudi Arabia and Egypt both run, and the UAE's multi-party network exchange. An invoicing or ERP setup that already clears ZATCA's Fatoora platform or Egypt's e-invoicing pipeline doesn't automatically clear the UAE's bar. It needs its own PINT AE-compliant export and an actual contracted relationship with an Accredited Service Provider behind it, not a checkbox that happens to carry the same name.
Wave 25's lookback rule is built to catch exactly that assumption. It looks at a business's highest VAT-subject revenue in any year from 2022 to 2025, so one that had a good year and has since quietly shrunk can still be in scope, while a newer business that has never cleared the threshold genuinely isn't, yet.
The appointment deadline sits months before the go-live date on purpose, and accreditation is gated by Peppol registration, UAE incorporation and PINT AE capability, so the list of qualified ASPs isn't unlimited. Waiting until the quarter before go-live means choosing from whoever is left, on their onboarding timeline instead of yours.
It isn't the same wiring. Saudi Arabia and Egypt both clear invoices through one government portal before they count as issued. The UAE routes the same invoice between two private Accredited Service Providers over the Peppol network and reports the tax data to the Federal Tax Authority afterward. A connector built for a single clearance portal has no equivalent step for a five-corner exchange.
Treat whichever deadline applies as a vendor-integration project with its own lead time, not a date to circle on a calendar. Confirming an invoicing or ERP system's PINT AE support, or shortlisting an Accredited Service Provider, is a decision worth making this quarter. The business that makes it next quarter is choosing from whatever options, and whatever queue, is left by then.
- 1Have you checked your VAT-subject revenue against Saudi Arabia's Wave 25 threshold for every year back to 2022, or only against this year's number?
- 2If you operate in the UAE, have you actually signed with an Accredited Service Provider, or only shortlisted a few?
- 3Does your invoicing or ERP system already export PINT AE-compliant data, or would UAE compliance mean building a new integration from scratch?
- 4If your business sells into more than one of Saudi Arabia, Egypt and the UAE, does your system handle each clearance model on its own terms, or is it still assuming one model covers all three?
