UAE VAT and Corporate Tax Compliance Suite

For several years UAE finance teams had one indirect tax to manage and a fairly stable rhythm around it: raise invoices with the correct treatment, file the periodic VAT return, pay, move on. Corporate tax changed the shape of the work. The same ledger now has to answer two different questions with two different definitions of income, over two different period cycles, with two sets of supporting evidence. VAT asks what was supplied, where, at what treatment, and in which emirate. Corporate tax asks what the accounting profit was, which items are added back or deducted to reach taxable income, whether relief or an exemption applies, and whether the entity qualifies for free zone treatment on that particular stream of revenue.

Generic accounting tax settings do not model the second question at all. Zoho Books will happily hold your registration number, apply a standard rate, split zero-rated and exempt supplies, and produce a summary you can transcribe onto a return. What it does not do out of the box is track emirate of supply across your revenue lines in the shape a return actually wants, distinguish reverse charge on imported services from reverse charge on imported goods with their own offsetting entries, evidence a designated zone movement, keep a running corporate tax provision that ties back to the trial balance, or maintain the qualifying versus non-qualifying revenue split that a free zone entity has to be able to demonstrate. Teams close that gap with spreadsheets rebuilt every quarter, and every rebuild is a new opportunity to get it wrong.

What ECOSIRE builds

A compliance layer that lives inside your Zoho org — not a separate system to reconcile against.

VAT modelled properly at the transaction, not at the report

We configure the tax rates, tax groups and tax treatments in your Zoho Books organization to match how you actually trade, then extend them with Deluge custom functions and custom fields so that each invoice, bill, credit note and expense carries the classification the return will need. Emirate of supply is captured on the transaction rather than inferred later. Reverse charge on imported services and on imported goods are treated as distinct flows with their own recoverable and payable postings. Designated zone and out-of-scope movements are flagged and evidenced. Where you have a mix of taxable and exempt activity, the input apportionment basis is applied consistently and recorded, so the method you used is defensible months later.

A return pack, not a screen you copy from

A scheduled Deluge function assembles the return package for the period: output tax analysed by emirate and by treatment, supplies subject to reverse charge, imports, adjustments, recoverable input tax with the apportionment working, and a control reconciliation between the return figures and the VAT control accounts in the general ledger. Every figure drills to the underlying document list. The pack is generated as a workbook plus a set of Zoho Analytics views, and archived to Zoho WorkDrive against the period so that you have the exact evidence set that supported each filing.

Corporate tax as a computation, not an estimate

We build a Zoho Creator application that holds your corporate tax workpapers and drives them from Books data. It pulls the accounting result for the tax period, then applies a configurable adjustment schedule you control: non-deductible expenditure, the entertainment restriction, interest deduction limitation inputs, exempt income, unrealised amounts, depreciation differences, and any relief you are eligible for. Each adjustment line references the accounts or transactions it came from, so the computation is auditable rather than asserted. The resulting tax charge is posted to Zoho Books as a provision journal through the Journals API on a schedule you approve, so management accounts carry the liability during the year instead of being restated at year end.

Free zone and group structure handling

For a free zone entity the application maintains a revenue classification per stream — qualifying activity, excluded activity, mainland-sourced, and non-qualifying — with the de minimis test computed and shown against its threshold each period. Where you operate several entities, each has its own Books organization and its own computation, with an intercompany schedule identifying related party transactions and the balances that will need disclosure. The rates, thresholds and relief parameters are configuration values you and your tax adviser set, not assumptions we bake in.

Calendars, alerts and evidence

Zoho Flow drives the compliance calendar: period-end lock reminders, return preparation windows, filing and payment due dates, and escalation if a pack is not approved by its internal deadline. Notifications route to the responsible owner in Zoho Cliq or by email. Every generated pack is versioned, so an amended return has a clear before-and-after. If the UAE e-invoicing programme applies to you within the engagement window, we scope the data-readiness work against the published requirements at that time rather than promising a certified integration.

Who this is for

UAE-registered businesses running Zoho Books that now file both VAT and corporate tax: mainland companies with multi-emirate revenue, free zone entities that must evidence a qualifying income split, and small groups with intercompany flows and related party disclosures. It suits finance functions of roughly five to a few hundred people where the tax workload has outgrown a quarterly spreadsheet but does not justify a dedicated tax system.

How delivery works

1. Scoping call. We walk through your entity structure, licences, emirate footprint, revenue streams, current VAT treatment map and how your corporate tax position has been determined so far, with your adviser present where possible. 2. Fixed quote. A written scope stating which entities, which returns, which adjustment lines and which reports are in build, at a fixed price. 3. Build. Tax configuration, Deluge functions, custom fields, the Creator computation app, Analytics views and the Flow calendar are developed against your real chart of accounts and a copy of your data. 4. Test organization. Everything is installed and run in a sandbox Zoho Books organization. We reproduce your last filed VAT return and your most recent corporate tax computation from the system and compare line by line to what you actually filed. Differences are explained before we go further. 5. Production install. The approved configuration is applied to your live organization, with the first live period run alongside your existing process as a parallel check. 6. Support window. We stay through your first live VAT filing and first corporate tax computation produced from the system.

An honest boundary

ECOSIRE builds software, not tax opinions. We are not a tax agent, we do not file on your behalf, and we do not determine whether your activity qualifies for free zone treatment or any relief — your adviser does, and the system is configured to their determination. What we deliver is a ledger that carries the right classification at the point of entry, computations that show their working, and evidence packs you can hand over without rebuilding them. Nothing here is pre-built or downloadable: it is built to order after a quotation, with a typical lead time of two to four weeks depending on the number of entities and the complexity of your revenue classification.
