eTAX Security Statement

The secrecy and confidentiality of taxpayers' information are our utmost concern.
We have taken the following security measures:
1.  The eTAX System, including Business Tax Portal (BTP), Individual Tax Portal (ITP) and Tax Representative Portal (TRP), has been designed and will be reviewed with reference to the latest best practice for Information Security Management as defined by ISO 27001 and ISO 27002.
2.  IRD's eTAX Services, including BTP Services, ITP Services and TRP Services, are operated in a secure site that use Transport Layer Security (TLS) encryption technology - a well-proven industry standard for encryption to ensure both confidentiality and integrity during data transmission over the Internet. All personal data provided to the IRD via eTAX System are secured, and access to them is restricted to authorised officers in the Department only.
3.  You have to use the following means to authenticate your identity every time you login your eTAX Account, including ITP Account, BTP User Account and TRP User Account. Your username for the ITP Account shall not be the same as your username for the BTP User Account and/or TRP User Account. Your password will be revoked upon 5 unsuccessful login attempts.
  
a. For ITP Account, your Tax Identification Number (TIN) and password or Digital Certificate or "iAM Smart".
  
b. For BTP User Account, your username and password or "iAM Smart".
  
c. For TRP User Account, your username and password or "iAM Smart".
4.  If your computer remains inactive for a period of time after login, the system will automatically log out itself to prevent any unauthorised access.
5.  Our web servers are protected by "firewalls" and our systems are monitored to prevent any unauthorised access.
6.  Stringent administrative control is put in place to monitor all access to the system and ensure that all transactions are properly authorised.
7.  We do not send personal information to you by unencrypted email nor embed hyperlinks in email for accessing your eTAX Account.
We recommend that you adopt the following practices :-
1.  Always remember to log out properly and close the browser after you have finished using eTAX Services.
2.  Do not use easy-to-guess characters (such as your birthday or Hong Kong Identity Card Number) as your password.
3.  Change your password on a regular basis.
4.  Access eTAX System only through the GovHK or the IRD's website or type the URL https://www.gov.hk/etax in the address bar of the browser.
5.  Avoid conducting transactions from public terminals.
6.  Install proper firewalls, anti-virus software and anti-spyware software in your computer, and update them on a regular basis.
7.  Do not disclose your password to anyone, including a person who claims to be a staff member of IRD.
8.  If you suspect any security breach or unusual activity, please contact us immediately at (852)183 2011.
