Between 6 and 8 September we incorrectly sent around 43,000 letters to tax agents instead of to their clients. This error was due to us incorrectly applying the tax agent mail redirect.
These letters were part of a wider campaign of over 650,000 emails and letters sent to businesses and employers, telling them about the Business Transformation changes coming in October.
If you receive one of these letters, you do not need to forward it to your client. Another reminder will be going to all businesses early next month around 4 October.
