Unique Transaction Reference Number (UTRN)

The UTRN can be found on:

• the submission receipt, if you've filed your SDLT return online

• the foot of page 2 of the paper return SDLT1

• on the payslip found on page 7 of the paper return SDLT1 (in the box marked 'reference number')

Enter 'none', if you do not have a UTRN
