Who can’t use the service

You need to buy other software or download other forms to send a Self Assessment tax return:

  • for a partnership
  • for a trust and estate
  • if you get income from a trust, you’re a Lloyd’s underwriter, a religious minister or you need to fill in the non-residence part of the return
