Must Read! How TIN Abuse Undermines Tax Compliance, Costs Government Billions

By Our Reporter

The abuse of Taxpayer Identification Numbers (TINs) is emerging as a major threat to tax compliance in Uganda, raising concerns over revenue losses and fairness in the business environment, tax experts have warned.

A TIN is a unique identifier issued by the Uganda Revenue Authority (URA) to individuals and businesses to facilitate tax administration. It enables URA to track taxpayers, process returns, and enforce compliance. However, misuse of TINs by some taxpayers has increasingly undermined the effectiveness of the tax system.

According to URA officials, common forms of TIN abuse include multiple TIN registrations by the same individual or business to conceal income, shift tax liabilities, or evade detection. In other cases, registered taxpayers fail to file returns but continue conducting business transactions, making it difficult for authorities to assess their true tax obligations.

The impact of such practices is far-reaching. Government loses significant revenue that would otherwise be used to fund essential services such as healthcare, education, and infrastructure. At the same time, compliant businesses face unfair competition from tax evaders who are able to offer lower prices by avoiding statutory obligations.

“There is also a growing concern about erosion of taxpayer morale,” a tax policy analyst noted. “When compliant taxpayers see others evading taxes without consequences, trust in the system weakens, and voluntary compliance declines.”

In response, URA has intensified efforts to curb TIN abuse. These include tightening TIN registration controls through enhanced verification processes and integration with national identification systems. The authority has also stepped up taxpayer education campaigns to raise awareness about compliance obligations and the risks associated with misuse of TINs.

Additionally, enforcement measures such as audits, penalties, and prosecutions have been strengthened, while digital systems like the Electronic Fiscal Receipting and Invoicing System (EFRIS) and Digital Tax Stamps (DTS) are being used to improve transparency and monitoring of business transactions.

Experts argue that while progress has been made, sustained enforcement, technology adoption, and taxpayer education remain critical to safeguarding Uganda’s tax system and ensuring equitable economic development.
