There are two ways you can file your end of year RWT withholding certificate (IR15). You can file the certificates electronically or alternatively you can print them off and send them to us. Read the information below to find out how:
You can also file your end of year New Zealand NRWT (non-resident withholding tax) withholding certificate (IR67) in the same way.
RWT/NRWT certificate details can be emailed to us in an electronic format. To make sure the file's secure, it must be encrypted.
The due date for RWT/NRWT certificates is 31 May.
Create your file(s) following the data format specified under file format.
Encrypt your file following the instructions under encryption requirements.
If you have multiple RWT/NRWT files, you can zip the files first, and then encrypt the zip file.

Files sent to us must be encrypted to a PGP level of data encryption. To encrypt your file(s), download our public key and import it into a PGP/GPG application.
You can download the public key by clicking on the link below. You will need to right click to 'save as' and make sure the file is saved with the extension '.asc'
The public key above will encrypt your file so there is no need to send us an additional password.
There are a number of software packages which will let you import our public key and encrypt your files including PGP Desktop and Gpg4win. Gpg4win software is free (as at 29 February 2012) and runs on Windows XP, Vista and 7. Both 32 and 64bit systems are supported.
Gpg4win is subject to a license agreement, which you should read before deciding whether to download Gpg4win.

There are other GPG and PGP applications available for Windows, Mac and Linux which can be used for file encryption. However, we don't have user instructions defined for those alternatives.
