Dominican ITBIS IT-1 Return

Compute ITBIS by rate, validate NCF and RNC, and build the DGII Formulario IT-1 figures

This module turns your posted sales and purchase invoices into a ready-to-file Formulario IT-1 worksheet for the Dirección General de Impuestos Internos (DGII) of the Dominican Republic. It classifies every line by its statutory ITBIS rate, computes the tax owed and the tax you may deduct, applies the withholdings suffered and your prior credit balance, and prints the exact casilla figures you transcribe into the DGII Oficina Virtual.

Built around the real DGII rules

ITBIS by rate of the IT-1

Lines are grouped into the rates of the IT-1 form (2020 edition, in force since the January 2020 period): 18%, 16%, 9% and 8% (Ley 690-16) and 0% / exento. Sales of depreciable assets (categories 2 and 3) are flagged on the invoice line and reported in casillas 15/20. Output tax (ITBIS facturado) and deductible input tax (ITBIS adelantado) are computed per rate with a deterministic, two-decimal HALF-UP money policy.

NCF / e-NCF validation

Every Número de Comprobante Fiscal is parsed and validated: pre-printed 11-char B series, 13-char electronic e-CF (E series), and legacy 19-char formats. The document-type code drives whether a purchase grants a deductible ITBIS credit: the Factura de Crédito Fiscal (01 / 31) does, consumo (02/32) invoices do not; purchases you support with your own comprobante de compras or pagos al exterior are listed for review.

RNC & cédula format

Company, partner and withholding-agent identifiers are checked for the shape the DGII uses: 9-digit RNC or 11-digit cédula. Identifiers of another shape are stopped before you file.

Withholding tracking

Capture the ITBIS withheld from you by third parties - large taxpayers, buyers of security services (Norma 07-2009), the State and card acquirers (Norma 06-2023) - per regime, with base, rate and source invoice. The total flows into casilla 30 and reduces the ITBIS payable.

21	Total ITBIS billed on sales
25	Total deductible ITBIS on purchases
26 / 27	Tax to pay / credit balance (21 - 25)
29	Prior period credit balance
30	ITBIS withheld by third parties
33	Difference to pay (equals casilla 38 when no surcharges apply)
34	New credit balance

Pre-filing validation

Before you transcribe anything into the Oficina Virtual, the module runs the IT-1 control set inside Odoo: company RNC format, valid filing month, per-rate base/tax consistency, output tax equal to the sum of per-rate ITBIS, mutually exclusive payable vs credit, and structural NCF/RNC checks on every line, plus a report of any purchase captured without its NCF — whose ITBIS is excluded from casilla 25 rather than silently claimed. Blocking errors are persisted on the return: the record moves to the Error status and the full list stays on the Validation Report tab, so you fix the data in Odoo rather than round-tripping the DGII tool.

Deterministic output

The worksheet is produced as readable text plus a flat CSV of every casilla, so the figures are auditable and reproducible to the cent — the printed worksheet, the CSV and the stored casilla fields are all produced from one single computation and carry the same amounts. An ITBIS retention on a vendor bill never nets off the input ITBIS, and a non-statutory tax percentage is reported naming the document that carries it.

One-click monthly wizard

Pick a year and month, confirm the company RNC, set any prior credit, and the wizard creates and computes the IT-1 return in a single step — for a DR ITBIS user, with no Settings administrator rights required.

Scope & boundary

This is a pure figures generator. It computes and presents the IT-1 declaration figures and worksheet from data already in your Odoo database. It does not transmit anything to the DGII and is not a certified filing agent - you file the IT-1 yourself through the DGII Oficina Virtual with your own credentials.

Built on the Odoo Community account base, it installs on Odoo 18, 19 and 20 with no Enterprise dependency.
