New tax regulations tighten data protections and audit rules by 2026

New tax regulations will come into force on April 1, 2026, following recent amendments. The Ministry of Finance has introduced changes aimed at improving transparency and efficiency in the tax system. These updates also strengthen protections for taxpayer rights while clarifying key procedures. The revisions set clearer limits on how taxpayer data can be accessed and used. Authorities must now follow stricter rules when disclosing information to government bodies, ensuring confidentiality remains intact. At the same time, the process for voluntary disclosures has been simplified, making it easier for taxpayers to correct past errors.

Taxpayers facing refund claims under review will now see their records retained for an additional two years. This extension applies to both document preservation and asset seizures during audits. The new rules also formalise how credit balances owed to taxpayers are processed, requiring authorities to follow standard refund procedures. The measures encourage voluntary compliance while reinforcing the accuracy of tax reporting. By refining data-sharing protocols and extending audit timelines, the Ministry aims to create a fairer and more reliable system.

The updated regulations take effect in early 2026, introducing stricter data protections and clearer procedures. Taxpayers will benefit from improved transparency and formalised refund processes. Meanwhile, authorities gain extended powers to preserve records during disputes, ensuring thorough reviews.
