DoliTax: IVA, ajustes fiscales y provisión del impuesto de sociedades

DoliTax computes, from your Dolibarr data alone, the three figures you currently rebuild by hand in a spreadsheet: VAT payable, tax add-backs and your corporate income tax provision.

No artificial intelligence, no external call, no data leaving your server: only SQL aggregations over your invoices. Same inputs, same results, to the cent: a computation you can show your accountant and reproduce identically six months later.

1. VAT grid

Net bases and VAT broken down by legal rate, on both the output and input sides, with the balance (VAT payable or VAT credit), by month, quarter or year.

All three chargeability regimes are actually implemented, not merely advertised:

• Accrual: at invoice date.
• Cash: pro rata of the payments received in the period.
• Mixed (French default): goods on accrual, services on cash.

You can switch regimes on screen, without changing your configuration, to compare before deciding.

Special rules applied under every regime: down-payment invoices always taken on a cash basis (French tax code art. 269-2 since 1 January 2023), optional input VAT deductible on payment (Moroccan default), deduction pro rata for partially taxable businesses. Any rate outside the configured legal list falls into an « Other rates: to be checked » bucket shown on screen: nothing is ever silently dropped.

2. Tax add-backs

A table of deductibility ceilings per accounting account, with three distinct semantics:

• Annual ceiling: add back the excess only (passenger car depreciation above the legal cap).
• Unit ceiling: add back the whole amount of any line whose unit price exceeds the threshold: a gift above the threshold is entirely non-deductible, not just its excess.
• Zero ceiling: fully non-deductible account (fines and penalties).

Amounts come from the general ledger when the Accounting module is populated, otherwise from supplier invoice lines. The source actually used is always displayed.

3. Corporate income tax cockpit

Turnover, net accounting profit, add-backs and tax provision, then the accounting to taxable to tax reconciliation, detailed bracket by bracket.

• Progressive scale (profit split across brackets, France 15 % then 25 %) or proportional by threshold (Morocco, Switzerland).
• Optional minimum contribution, due even at a loss (Morocco).
• Scale stored per fiscal year: a new finance act does not break your history.

France, Switzerland, Morocco: and fully configurable

Three presets apply the country's rates, regime, ceilings and tax scale in one click. Everything stays editable: legal rates, ceilings, brackets, down to the account prefixes: essential outside the French chart of accounts, since Moroccan turnover sits in the 71x range.

What this module does not do

DoliTax is a pre-computation and management control tool, not tax-return software. This version does not handle offset fiscal years, reverse charge, import or margin VAT, structurally non-recoverable VAT, loss carry-forward or tax credits. These limits are stated plainly in the README shipped with the module: a clear boundary beats a wrong figure.

Technical

• Two tables only, kept if you disable the module. No hook, no trigger: pure read access to your data.
• 63 integration assertions checked to the cent: VAT grid under all three regimes, down payments, pro rata, all three ceiling types, French, Swiss and Moroccan scales, minimum contribution, period boundaries.
• Works with Dolibarr V18 to V24 and PHP 7.4 to 8.3. No dependency, no composer, no third-party service.
• Two separate permissions: dashboard access, and configuration.
