Tax Treaty Amendments clarify residency, dividend withholding limits, information exchange, and cross-border tax collection assistance. Amendments revise definitions and residency to base residence on liability to tax under domestic criteria while excluding persons taxed only on source income and limiting partnership/trust application; restructure dividends to allow recipient state taxation with capped source state withholding for beneficial owners resident in the other State and special treatment for certain investment vehicles; delete the partnerships article; expand exchange of information and add provisions for tax examinations abroad, assistance in collection of revenue claims, and a limitation of benefits clause to deny treaty advantages when a principal purpose is obtaining them.
