Tax prep support

Sales tax and nexus support

Short answer

Finbryn tracks when your Saudi revenue crosses a new obligation, the SAR 40 million VAT monthly-filing threshold and each falling Fatoora Phase 2 integration threshold, then prepares the VAT return workpapers and e-invoicing readiness checklist from your reconciled books before ZATCA's deadline arrives.

The threshold that changes your filing calendar

VAT registration in Saudi Arabia is close to universal once a business trades commercially, so the obligation most growing companies actually watch is the filing frequency threshold: cross SAR 40 million in annual taxable supplies and the return moves from quarterly to monthly. We check your rolling twelve-month supplies against that figure every close, not once a year, so the switch is expected rather than discovered from a ZATCA notice.

Building the return from reconciled books

Each VAT return is built from the same reconciled sales and purchase ledgers our bookkeeping team already produces, mapped to standard-rated, zero-rated and exempt categories under Saudi VAT rules. Where a business sells across GCC member states or into free zones, we flag the treatment separately rather than assuming every sale carries the standard 15% rate.

Fatoora integration, wave by wave

ZATCA has been lowering the revenue threshold for Phase 2 e-invoicing integration in successive waves, so a business that was below the line last year can find itself notified this year. We monitor where your VAT-subject revenue sits against the current wave and prepare the integration readiness checklist, the connected invoicing setup and the workpapers ZATCA expects, ahead of the deadline it assigns rather than after the notice lands.

Filing deadline, every period

Whichever cycle applies, the return itself is due by the last day of the month following the tax period. We build the draft early enough in that window that a review happens before the deadline, not on it.

Who reviews and submits

We prepare the VAT return workpapers and e-invoicing readiness documentation. A ZATCA-licensed tax agent reviews the position and handles submission or any ZATCA correspondence that follows.

Where this fits

This pairs with monthly bookkeeping, which keeps the sales and purchase ledgers current enough that a VAT return is a review, not a rebuild. See pricing for VAT preparation rates.

Questions

Frequently asked questions: Sales tax and nexus support

How do we know when our VAT filing moves from quarterly to monthly?

Once your annual taxable supplies pass SAR 40 million, filing moves to monthly. We track your rolling twelve-month supplies each close so the switch is not a surprise.

Does Fatoora Phase 2 apply to us yet?

It depends on your VAT-subject revenue against ZATCA's current wave threshold, which has been falling with each round. We check where you sit and prepare the integration workpapers ahead of the deadline ZATCA assigns.

Who actually submits the VAT return?

We prepare the return workpapers from your reconciled books. A ZATCA-licensed tax agent reviews the position and submits it, or handles any related ZATCA correspondence.

What happens if a VAT filing deadline falls on a public holiday?

ZATCA extends the deadline to the next working day when it falls on an official holiday, and we build our own internal timeline around the original date so the extension is a buffer, not the plan.

How do you know where we owe tax?

We review your sales by state against each state's economic nexus threshold and flag where a new obligation has started.

Do you file the returns yourselves?

We prepare the return workpapers; filing is handled by a registered filing partner or transmitted through your sales-tax automation platform.

How is sales tax and nexus support priced?

Pricing for sales tax and nexus support depends on your transaction volume, the software you use, and how much cleanup is needed before ongoing work starts. Current ranges are published on the pricing page, and your exact fee is confirmed in writing before anything begins.

What software works with sales tax and nexus support?

Sales tax and nexus support runs inside Avalara or TaxJar, whichever you already use. If you are not yet set up in either, we can configure a file in your name so you keep ownership of it once the engagement is under way.
