DoliTax · FOR DOLIBARR

Your VAT and corporate tax figures,
straight from Dolibarr.

DoliTax reads your validated invoices, payments and ledger and produces three screens: the VAT grid (collected and deductible by rate, balance due), the tax add-backs by deductibility ceiling and the corporate tax cockpit. Deterministic SQL, no external call.

YOUR DAILY WORKFLOW

What changes once the module is active.

01

The VAT return prepared, not rebuilt in a spreadsheet

Net bases and VAT broken down by legal rate, collected and deductible, with the balance (VAT payable or VAT credit) by month, quarter or year. Accrual, cash or mixed regime, switchable on screen to compare. Amounts on an unexpected rate land in an “Other rates: to be checked” bucket, never dropped.

02

Add-backs that follow the rule, not an estimate

A ceiling per accounting account with three semantics: annual (add back the excess), unit (add back every line whose unit price exceeds the threshold) and zero (fully non-deductible). Figures come from the ledger when the Accounting module is populated, otherwise from supplier invoice lines, and the source used is displayed.

03

A corporate tax provision you can show your accountant

Turnover, net accounting profit, add-backs, taxable profit and tax, bracket by bracket. Progressive scale (France 15 % then 25 %) or proportional by threshold, optional minimum contribution, scale stored per fiscal year.

INSIDE THE MODULE

The VAT grid

Period selector (month, quarter, year), a drop-down to view the grid in another regime without changing the configuration (here “Mixed: goods on accrual, services on cash”), and a reminder of the scope: validated and paid invoices only, credit notes negative, down payments on a cash basis. Two tables, VAT invoiced (collected) and VAT recoverable (deductible), list the net base and VAT for each legal rate (20, 10, 5.5, 2.1 %) with totals, then the VAT balance due.

Before you choose.

Does it generate the CA3 return?

No. It gives the net bases and VAT by rate, collected and deductible, and the balance for the period, in the shape you carry over to the return. An option rounds displayed amounts to the currency unit as the CA3 or SIMPL forms do. Filing stays in your tax portal.

Which VAT regimes are supported?

Accrual (invoice date), cash (pro rata of payments received in the period) and mixed (goods on accrual, services on cash, the French common-law regime). Down-payment invoices are always taken on a cash basis. You can view the grid in another regime without changing the configuration.

Where do the add-back amounts come from?

From the general ledger when the Accounting module is populated, otherwise from supplier invoice lines through their accounting allocation. The screen always states the source used. Unit ceilings compare the unit price including tax, line by line.

Can I use it outside France?

Yes. Presets exist for France, Switzerland and Morocco (proportional scale by threshold, minimum contribution, input VAT deductible on payment). Legal rates, ceilings, brackets and account prefixes are editable, which matters outside the French chart of accounts.

Does the figure match the native Dolibarr VAT report?

Situation invoices are handled exactly like the native report so both agree. Drafts and abandoned invoices are excluded, credit notes are counted negatively. In cash regime, VAT is rounded per period, so a multi-instalment invoice can differ by one cent across periods.

Does it write anything into my accounting?

No. The module only reads invoices, payments and ledger entries. It stores only its tax brackets and ceilings in two tables, which are kept if you disable it.
