Corporate Tax 2026

DOMINICAN REPUBLIC Trends and Developments Contributed by: Luis Miguel Pereyra, Pereyra & Asociados

A practical playbook for 2026 readiness Finance and tax teams should address the following in Q1–Q2, 2026. • E-invoicing roadmap: (a) confirm taxpayer classification and the applica - ble deadline (large/medium firms, 15 November 2025; micro/small/unclassified/state, 15 May 2026); (b) begin certification with the DGII, select an electronic invoicing service provider ( proveedor de servicios de facturación electrónica – PSFE)/ certified vendor and complete ERP/accounting integration; and (c) implement controls for real-time eCF valida - tion and ten-year archiving, with audit trails and data retention policies aligned to statutory requirements. • Monthly filings alignment: (a) automatically reconcile ITBIS (IR 17/IR 3) and forms 606/607 with eCF data; and (b) implement variance checks that flag discrep - ancies between invoicing data and returns before filing deadlines. • Excise modelling: (a) for alcohol and beverages, simulate margins under the new specific and ad valorem rates; and (b) evaluate reformulations, pack sizes and price points to manage both compliance and profit - ability. • Policy watchlist: (a) track DGII notices on eCF timelines, platform rules and any revived fiscal reform components ( anticipos régimen simplificado de tributación – RST; simplified tax regime); and (b) establish an internal change log for tax set - tings, ensuring consistent and timely updates across systems and teams. Small and micro businesses should consider the fol - lowing. • Do not defer eCF: (a) the 15 May 2026 deadline is firm – late adop - tion risks fines, system disruptions and lost sales if counterparties require eCF; and (b) consider the DGII free e-invoicer or certified

building, updated proposals are expected around or after the budget season. Crucially, the government has signalled it can boost collections via administrative measures, e-invoicing expansion, promoting traceability for alcohol and cig - arettes, and tech-enabled controls without an imme - diate congressional tax bill. That implies two parallel tracks for small businesses. • Administrative compliance will tighten regardless of statutory reform timing: Firms should invest now in process upgrades for eCF readiness, inventory controls and documentation traceability, even as they stay alert for simplification windows that will reduce compliance burdens once enacted. • Legislative simplification is still on the horizon and worth watching: When relief measures on anticipos or simplified regimes return to the agenda, they may materially improve net cash flows. Small busi - nesses that have already modernised their pro - cesses will be best positioned to capitalise quickly. Multinationals and the digital economy: documentation, withholding and special regimes Authorities have repeatedly identified cross-border digital services, sector incentives and special regimes as leakage points. The year 2026 is likely to bring more stringent withholding rules, updates in treatments for certain cross-border flows and tighter documentation requirements. For multinationals: • intercompany and cross-border transactions should be reconciled against eCF frameworks where applicable, with consistent codes and descriptions that facilitate DGII validation; • digital platform services (from advertising to cloud and streaming) are an explicit focus for consump - tion tax coverage – local tax teams must map ser - vice flows, identify taxable events and align returns with eCF data; and • special regimes and incentives will face ration - alisation pressures – firms relying on preferential treatment should prepare for changes in eligibility, reporting or benefit calculation.
