The study in Jordan found that elements of the tax system like tax laws and administration help reduce tax evasion. They surveyed 140 tax auditors and discovered that better governance mechanisms also play a role in decreasing tax evasion. The researchers suggest raising awareness among taxpayers, avoiding frequent changes in tax laws, and imposing stricter penalties on tax evaders. It's important to release official statistics on tax evasion to combat exaggerated claims and ensure effective policies are in place.
