Where do I find my company's tax reference and Government Gateway sign-in?
For the Company Tax Return you need two things that belong to the company.
The Unique Taxpayer Reference (UTR)
A 10-digit number that HMRC gave the company for Corporation Tax. It is on letters from HMRC about the company's Corporation Tax. [Draft note: OWNER TO ADD: GOV.UK link to find a lost company UTR.]
The Government Gateway sign-in
The company's user ID and password for HMRC's online services for Corporation Tax. [Draft note: OWNER TO ADD: GOV.UK link to set up or recover them.] The Government Gateway account is the company's, not your personal one.
What Yearfile does with them
We ask for the sign-in when we send your return. We use it once, in memory, to send the return. We do not store it and we do not write it to a log. Close the page after you have filed.
