About this service

This service allows you to file the annual company's income tax return, online. This is the same as completing the Income tax return: Companies 2015 (IR4) form. You should set aside an hour to complete this return online and already have available your income details for the 2015 year.

When to use this service

Use this service once you have received a letter detailing your company's registration details or your IR4 income tax return in the mail and are ready to file it online with IRD.

The numbers to the right of the input field of the online return correspond to the question numbers on the paper IR4 return. This means you can use the IR4 guide to help explain each step when filing online.

What you will need

• The company's income details for the 2014-2015 period.
• The company's IRD number - if you do not have this call us on 0800 377 774.
• The DLN number is the 14-character number printed either in the text of the letter we sent you or at the top right or bottom of your paper return. If you don't have this number either call us on 0800 377 774 or download a printable return to complete and send back by post.
• Access to a printer. You must print a copy of your return so please ensure your computer is connected.
