Which wave is your business in?

ZATCA brings businesses into e-invoicing Phase 2 in batches it calls waves. Each wave has a minimum revenue threshold and its own integration date. Pick your revenue band and you will see your wave and your date.

What was your annual VAT-taxable revenue, in your highest year between 2022 and 2025?

Pick the band that applies to you. Your result appears directly below.

Choose a revenue band to see your wave and your integration date.

No wave announced Less than 187,500 SAR

Not in any announced wave yet

What to do about it

  • You are not in an announced wave yet — but Phase 1 (generation and storage) has applied to every taxpayer subject to the regulation since 4 December 2021.
  • VAT registration is mandatory once annual taxable revenue exceeds SAR 375,000.
  • Watch ZATCA’s announcements: every new wave lowers the revenue threshold.

ZATCA’s notice to your business is the authoritative answer. This tool is an inference from the published criteria.

What to do about it

What Phase 2 actually requires

Four technical obligations, no more and no fewer

Integrate with the Fatoora platform

Your invoicing solution connects to Fatoora over an API, after a cryptographic stamp identifier is issued for each solution unit.

A specified invoice format

Invoices are issued as XML (or PDF/A-3 with embedded XML) carrying a digital signature, QR code, UUID and a hash chaining to the previous invoice.

Real-time clearance, 24-hour reporting

Standard tax invoices (B2B) are cleared before you hand them to the customer. Simplified tax invoices (B2C) are reported within 24 hours of issue.

Six months’ notice

ZATCA notifies every targeted business at least six months before its integration date. That notice is the authoritative answer for your wave.

The full reference

Every announced wave

Newest first. A business falls into the first wave from the top whose threshold its revenue exceeded in one of the reference years, and a later fall in revenue does not release it.

Common questions

How is my wave determined?

By one criterion only: your total VAT-taxable revenue in the reference years ZATCA names for each wave. It has nothing to do with your sector, headcount or entity type. You fall into the first wave from the top whose threshold your revenue exceeded.

If my revenue drops, am I out of my wave?

No. The obligation is built on exceeding the threshold in a reference year. If you exceeded it in an earlier reference year you are bound to that wave, and a later fall in revenue does not lift it.

What if I never received a notice from ZATCA?

ZATCA notifies targeted businesses at least six months before the integration date, through the channels registered against your account, and it appears in your Fatoora account. Not receiving a notice is not an exemption — check your account and contact ZATCA if your revenue is above one of the announced thresholds.

Does this tool replace ZATCA’s notice?

No. This tool is an inference from the published criteria; the notice issued to your business is the authoritative answer. The tool is for placing yourself quickly and planning before the notice arrives.

How long does getting ready take?

The longest part is usually obtaining the cryptographic stamp identifier and testing the connection, which can take weeks. Waiting until the final month before the date is the most common reason businesses miss it — which is why each wave gets an integration window rather than a single day.

Is Mezan ready for Phase 2?

Yes. Mezan is integrated with the Fatoora platform and issues e-invoices under both Phase 1 and Phase 2, including from the POS. We can set the integration up for you as part of your subscription, with no separate setup fee.
