DRC Mid-Year Regulatory Roundup: Key Changes in H1 2026

← Back to Bulletin

Last reviewed: October 2, 2026

The first half of 2026 has been one of the most active compliance periods for businesses operating in the Democratic Republic of Congo in recent years. The Direction Générale des Impôts (DGI) has intensified enforcement across several tax obligations, the Electronic Fiscal Device (EFD) rollout has passed a critical implementation milestone, and the social security administration (CNSS) has tightened monitoring of employer declarations. This roundup covers the key regulatory developments from H1 2026 and the compliance priorities businesses must address over the remainder of 2026.

1. Electronic Fiscal Devices (MEF): Enforcement Now Active

Businesses that have not yet deployed compliant EFD devices under the DGI's MEF (Machines Électroniques de Facturation) programme — particularly those classified as Grands Contribuables or with annual TVA-registered turnover above CDF 80 million — are exposed to formal penalties. The programme's current enforcement stage, and the deployment deadline applicable to your taxpayer category, should be confirmed with your DGI provincial office.

The monthly reconciliation obligation between EFD transaction data and TVA declarations has become a standard audit trigger. DGI auditors are now routinely comparing MEF data (transmitted automatically to the tax system) against the monthly TVA-3 declaration. Unexplained variances are generating audit correspondence with increasing frequency.

Practical steps if you are not yet compliant:

• Register immediately with a DGI-approved MEF supplier (contact the DGI provincial office for the current approved supplier list in your province).
• Prioritise device deployment and staff training on receipt issuance protocols — incorrect receipt format is itself a compliance breach.
• Reconcile historical TVA declarations against any EFD transaction data already transmitted to identify any gaps before the DGI does.

2. TVA (Value Added Tax): H1 Filing Experience and Common Errors

The standard DRC TVA rate is 16%, in force for the 2026 fiscal year, alongside reduced rates and a 0% rate on exports and assimilated transactions. TVA returns (TVA-3) must be filed by the 15th day of each month in respect of transactions made the previous month. H1 2026 compliance monitoring has revealed several recurring error patterns that DGI audit teams are flagging:

• TVA credit misclassification: Businesses classifying non-recoverable TVA (on entertainment, fuel for non-business use, or purchases from non-TVA-registered suppliers) as recoverable input credits.
• Reverse charge omissions: Failures to self-assess TVA on imported services from non-resident suppliers — a requirement that applies to services from foreign consultants, technology providers, and group service companies.
• EFD/declaration reconciliation gaps: As noted above, variances between MEF data and TVA-3 declarations.
• Late submission penalties: A late TVA declaration (even if the TVA balance is nil) triggers automatic penalties. Set calendar reminders for the 15th of each month.

3. Impôt sur les Bénéfices et Profits (IBP): Provisional Instalments for 2026

For companies with a December 31 financial year-end, corporate income tax for 2026 is paid in three provisional instalments, not four quarterly ones: 30% before 1 August, 30% before 1 October and 20% before 1 December of the year in which the taxable income is earned. That schedule has applied since 1 January 2024; it replaced a regime of four instalments each representing 20% of the tax paid during the previous fiscal year. The first two instalments for 2026 have therefore already fallen due, and the remaining payment is the 20% instalment due before 1 December 2026. The balance is settled with the annual corporate income tax return, which is due by 30 April of the following year. Non-payment or underpayment of instalments generates late payment interest that accrues daily.

Finance teams should confirm the following before the 1 December 2026 instalment deadline:

• The correct instalment base — each instalment is a fixed percentage (30%, 30%, 20%) referenced to the year in which the taxable income is earned, not to the prior year’s DGI-assessed liability as under the pre-2024 rules
• Whether any tax credits, advance tax payments, or withholding tax deductions reduce the instalment base
• The correct DGI payment reference and bank account (payments must reference the specific tax period and taxpayer number)

4. CNSS (Social Security): Declaration and Payment Compliance

The Caisse Nationale de Sécurité Sociale has maintained active monitoring of employer contributions throughout H1 2026. CNSS contributions in the DRC comprise employer and employee portions for pension (retraite) and family benefit (prestations familiales) branches. Key compliance points:

• The INSS/CNSS, INPP and ONEM returns are all due by the 15th day of the month following the month in which the salary was paid — INPP is therefore a monthly obligation filed alongside the social security return, not a one-off annual payment. Late declarations trigger penalty surcharges.
• All employees — including expatriates subject to CNSS under the local regime — must be declared on the monthly payroll bulletin (bulletin de salaires).
• Arrears accumulation is a recurring audit risk.
• Companies with workforce reductions or restructurings must notify CNSS of any changes to declared employee headcount.

5. Transfer Pricing: DGI Focus on Cross-Border Transactions

DRC tax law requires companies established in the DRC that are dependent, in law or in fact, on companies or groups of companies established outside the DRC and whose annual turnover excluding tax is equal to or exceeds USD 1 million to file a simplified transfer pricing documentation declaration, on paper or electronically, using the tax administration’s template. That declaration is due within two months of the deadline for filing the annual corporate income tax return, which is itself due by 30 April of the following year. Businesses with cross-border transactions with related parties — including management fees, technical assistance fees, intercompany loans, and royalties — are required to maintain contemporaneous transfer pricing documentation demonstrating that intercompany prices comply with the arm's length principle.

Companies that cannot produce contemporaneous documentation face both primary transfer pricing adjustments and penalty surcharges on underpaid tax. If your business has not yet prepared transfer pricing documentation for FY2024, FY2025 or the current FY2026, this should be prioritised before any DGI audit correspondence arrives. On the two-month rule, the FY2025 simplified declaration fell due by 30 June 2026 and is already late for any business that has not filed it; the FY2026 declaration falls due by 30 June 2027.

Q4 2026 Key Compliance Calendar

Date	Obligation	Notes
15 October	TVA-3 declaration (September period)	Must reconcile with MEF data
15 October	CNSS/INPP/ONEM declarations (September payroll)	Include all employees; expatriates as applicable
15 November	TVA-3 declaration (October period)	Standard monthly deadline
15 November	CNSS/INPP/ONEM declarations (October payroll)	INPP is a monthly obligation filed with the social security return, not a one-off payment
Before 1 December	Third provisional corporate income tax instalment (20%)	Final 2026 instalment — see section 3
15 December	TVA-3 declaration (November period)	–
15 December	CNSS/INPP/ONEM declarations (November payroll)	Due by the 15th of the month following the month the salary was paid

Regulatory compliance in the DRC requires active calendar management. A single missed filing triggers a cascading penalty obligation that is disproportionately difficult to unwind. The best defence is a structured monthly compliance checklist reviewed by a dedicated finance or compliance officer.
