Hello Community Users, we wanted to add an update to this thread. Previously adding an accountant user to the UK Self Employed product was not available to all Self-Employed users however this has changed. To add an accountant just go to the settings ⚙ in the top right and you should see> accountant>invite your accountant and you can add your accountants email address to invite them.
If you do not see that option please reply here and we'll investigate into it and go through the resolution with you.
