[CoinDesk] Hong Kong passes law requiring crypto exchanges to report customer transactions to tax authorities

Hong Kong’s legislature passed a law requiring crypto exchanges to collect customer and transaction data starting in 2027, with the territory sharing that information with overseas tax authorities from 2028. The rules extend Hong Kong’s tax-transparency framework to digital-asset platforms, tightening reporting obligations for exchanges operating in the jurisdiction. The change matters because it brings crypto trading into the same information-sharing system long applied to traditional finance, raising compliance burdens for platforms and potentially affecting how overseas clients use Hong Kong venues. What to watch next is how exchanges implement data collection ahead of the 2027 start and which foreign tax authorities begin receiving reports in 2028.
