A significant change proposed in the Finance Bill 2026 will reduce the tax rate on unexplained income from 60% to 30%, according to details released today. The move, effective from April, represents a shift towards a system of proportionate taxation, although authorities maintain they will continue to rigorously investigate income sources.

The bill's authors state the reduction aims to balance revenue collection with fairness, acknowledging that in some cases, difficulties in immediately proving income origins may exist. However, officials emphasized that the lower tax rate does not imply a relaxation of scrutiny. Investigations into the source of unexplained income will remain a priority to prevent tax evasion and illicit financial activities.

The current 60% tax rate on unexplained income was introduced to deter the accumulation of wealth from undeclared sources. The reduction to 30% is intended to address concerns that the previous rate was excessively punitive, particularly in situations where proving the origin of funds proved challenging. The Finance Bill 2026 is currently under review by parliament and is expected to be debated in the coming weeks before a final vote.

Experts suggest the change reflects a broader trend towards simplifying tax regulations and promoting compliance. The government has indicated that further measures to enhance transparency and combat financial crime are also under consideration, complementing the adjustments outlined in the Finance Bill 2026. The precise impact of this change on government revenue remains to be seen, but officials are confident that robust enforcement mechanisms will ensure continued compliance.
