On 29 October 2026, Hong Kong signed a comprehensive avoidance of double taxation agreement (CDTA) with the Lao People’s Democratic Republic in Hong Kong. Financial Secretary Paul Chan witnessed the ceremony; Acting Secretary for Financial Services and the Treasury Joseph Chan and Laos Deputy Minister of Finance Soulivath Souvannachoumkham signed. For overseas directors and investors who use a Hong Kong company for ASEAN or Belt and Road exposure, this is a treaty development worth tracking — but it is signed, not yet in force.

This page summarises the IRD and ISD press materials only. Do not assume the reduced withholding rates apply until both sides have completed ratification and the agreement has entered into force. Check the IRD CDTA pages for current status before relying on any treaty benefit.

Why CDTAs matter for overseas Hong Kong company owners

At a high level, a CDTA allocates taxing rights between jurisdictions, helps investors assess cross-border tax liabilities, and aims to avoid double taxation on the same income. For groups that route investment, dividends, or financing through a Hong Kong company into Laos (or that receive Laos-sourced income as Hong Kong residents), clarity on which side may tax which income — and whether foreign tax can be credited — is often part of structuring and cash-flow planning.

None of this replaces tax advice. Treaty residence, beneficial ownership, limitation-on-benefits style rules (where applicable), and domestic anti-avoidance can all affect outcomes. For company setup context, see our Hong Kong company incorporation guide for overseas clients and Hong Kong vs BVI company structure.

Key points from the press release

Per the official announcements, the Hong Kong–Laos CDTA is:

  • Hong Kong’s 61st CDTA overall;
  • the sixth signed this year;
  • the 16th signed by the current-term Government.

On substance highlighted for investors:

  • Taxing rights — the agreement allocates taxing rights so investors can better assess cross-border liabilities and avoid double taxation.
  • Foreign tax credit — tax paid by Hong Kong residents in Laos may be allowed as a credit against Hong Kong tax on the same income, subject to the Inland Revenue Ordinance (Cap. 112).
  • Laos withholding tax on dividends for Hong Kong residents: currently 10%, reduced under the CDTA to a minimum of 5%.
  • Laos withholding tax on interest for Hong Kong residents: currently 10%, reduced under the CDTA to 5%.

Exact conditions, definitions, and any residual domestic rates are in the treaty text and domestic law — wait for the gazetted order and IRD guidance rather than relying only on the press summary.

Status: signed but not yet in force

The CDTA comes into force only after ratification by both sides. In Hong Kong, the Chief Executive in Council makes an order under the Inland Revenue Ordinance; that order is then tabled at the Legislative Council for negative vetting. Details will appear on the IRD website when available. Until entry into force, treat the current Laos withholding rates as continuing to apply for planning purposes, and diary a follow-up when the order is gazetted and LegCo vetting is complete.

ASEAN and Belt and Road context

Laos is an ASEAN member state and a Belt and Road participant. With this signing, Hong Kong has CDTAs with seven ASEAN member states, covering more than 70% of ASEAN population and GDP — a network point for groups that use Hong Kong as a regional holding or financing hub. For the full list of Hong Kong’s CDTAs, see the IRD comprehensive double taxation agreements page.

Practical takeaways for Harbor clients

  • Watch ratification — signed on 29 Oct 2026; not in force until both sides complete approval and the HK order completes LegCo negative vetting.
  • Map dividend and interest flows via Hong Kong — if you have (or plan) Laos-sourced dividends or interest received by Hong Kong residents / HK companies, note the press-release WHT reductions (dividends to a minimum of 5%; interest to 5%) and the foreign tax credit framing under Cap. 112.
  • Do not assume the new rates apply yet — contracts, cash forecasts, and board papers should flag “subject to entry into force” until IRD confirms.
  • Keep structuring and compliance separate — treaty benefits sit alongside Hong Kong incorporation, accounts, and audit calendars. See HK incorporation, HK accounting & audit, and our comparison of HK vs BVI.
  • Read the primary sources before instructing agents; secondary summaries can lag behind the gazetted order.
