If you're self employed, that's not a problem at all!
We'll need proof from HMRC to confirm this though. Please send one of the following documents to us:
Welcome letter with confirmation of your UTR number
Notice of Self-Assessment tax return
VAT certificate, if applicable
If you do not already have a letter from HMRC or any of the above documents, you can request confirmation of your UTR number directly from HMRC by calling them on 0300 200 3310.
