Law & Regulation
Council of Ministers Decision No. 39 of 2019 Issuing the Executive Regulations of the Income Tax Law
The Executive Regulations operationalise the Income Tax Law by developing computation, registration, filing, documentation, withholding, assessment, audit, objection and administrative procedures. They should be consulted for how the statutory tax framework works in practice, while later amendments and GTA materials must be version-controlled.
Legal Significance
What This Instrument Does
Converts the parent Law's framework concepts into procedural and calculation rules, clarifying evidence, timing and taxpayer-GTA interaction.
Why It Matters
Many tax failures arise not from misunderstanding that tax exists but from using the wrong method, documentation, deadline or filing route. In project transactions, these mechanics influence model assumptions, contractor payments, compliance covenants and closing diligence.
Key Provisions
- Tax registration and taxpayer files
Operational requirements for entering and maintaining the tax administration system.
- Source and permanent-establishment application
Detailed application of nexus and attribution concepts in the parent Law.
- Accounts and taxable-profit adjustments
Computation mechanics, accounting support and adjustments to commercial accounts.
- Deductions, depreciation and losses
Conditions and evidence for claiming costs, capital allowances and loss treatment.
- Related-party documentation
Practical transfer-pricing and evidentiary expectations where applicable.
- Withholding procedures
Deduction, remittance, reporting and supporting documentation for covered payments.
- Returns, payment and records
Filing mechanics, retention and substantiation requirements.
- Audit and information requests
GTA review processes and taxpayer response obligations.
- Assessments and estimated treatment
Administrative determination where filings are absent, incomplete or adjusted.
- Objections and procedural time limits
How challenges are initiated and supported; exact periods must be checked in current text.
- Refunds, collection and penalties
Administrative handling of amounts due, overpayments and non-compliance.
- Electronic administration
Procedures increasingly delivered through the GTA's digital platform, without replacing statutory requirements.

InfraLex Relevance
This is the operational companion to Law No. 24 of 2018. Its strongest product value is a map from legal obligation to evidence and procedure. Technical forms and portal instructions should be linked as guidance, not misclassified as legislation.
