Hong Kong Flips On Crypto Reporting in 2027, South Korea Pushes Tax to 2029

Hong Kong's Legislative Council waved through new crypto tax-reporting legislation on November 4, 2026, and the clock starts ticking fast. Under the OECD's Crypto-Asset Reporting Framework (CARF), exchanges and other qualifying intermediaries must start collecting data on customers' tax residency and their digital asset moves. The first reporting period opens in 2027, with authorities scheduled to begin swapping that information internationally in 2028, according to the Hong Kong Inland Revenue Department.

The net is wide. Covered providers have to log fiat-to-crypto buys and sells, crypto-to-crypto swaps, and reportable transfers out to external wallet addresses. That last one is the sharp edge: if you buy Bitcoin on a regulated platform and ship it to a hardware wallet, the exchange may have to flag the transfer even though it has no idea what you do with the coins next. A withdrawal isn't automatically a taxable sale — but it is now visible.

South Korea is taking the opposite tack. The government said on November 5 that it will ask parliament to push crypto gains taxation all the way to January 2029 — the fourth time the levy has been kicked down the road since it was first slated for 2022. As things stand, annual crypto gains above 2.5 million won would face a combined 22% national and local tax, and that threshold applies to qualifying gains, not the total value of coins sold.

Why the stall? According to Yonhap News Agency, Seoul pointed to planned virtual-asset information exchanges with the United States landing in 2029 as a reason to wait. The logic is simple: tax authorities could see everything happening on domestic platforms while flying half-blind on overseas trades, which would make enforcement messy and compliance burdens lopsided. Officials also want a public-private working group to sharpen the rules, plus a separate proposal letting crypto losses carry forward for up to three years. Neither the delay nor the loss treatment is locked in — parliament still has to sign off.

The reporting puzzle gets thornier when cost basis enters the room. Picture buying 1 ETH for $2,000 on Exchange A, moving it to a personal wallet, then selling it for $3,000 on Exchange B. The second platform can see the $3,000 in proceeds but has no reliable window into the $2,000 you paid. The real gain — $1,000 before fees — can't be reconstructed from one side of the trade, and that's precisely where cross-border reporting frays.

Hong Kong and Seoul aren't operating in a vacuum. The European Union's DAC8 framework chases similar transparency through standardized crypto-asset reporting, and U.S. broker-reporting rules under Internal Revenue Code Section 6045 aim at the same visibility, with different scope and timing. None of these systems decide whether you owe tax — they just build the paper trail. Self-custody stays legal, but moving coins off an exchange no longer means moving them out of sight.
