India and Japan on Saturday signed an agreement to amend the Double Taxation Avoidance Agreement (DTAA) which will help in reducing tax avoidance and act as a deterrent against tax evasion. The agreement was signed in the presence of Prime Minister Narendra Modi and Japanese Prime Minister Shinzo Abe. This pact amends the convention between India and Japan for the avoidance of double taxation and the prevention of fiscal evasion with respect to taxes on income, signed in 1989, an official statement said.
