Which CDS Step Takes the Longest?
What Is the Slowest Step?
The slowest step in CDS registration is getting a Unique Taxpayer Reference. It arrives by post in around 10 working days, while every other stage takes minutes to hours. If you start it last, it holds up the whole process.
Why the Post Slows You Down
The UTR is a 10-digit number that proves your business identity to HMRC. Companies get one at formation, but sole traders must register for Self Assessment and wait for the letter. This waiting time paces your whole registration, as explained in this guide on how to register for CDS UK.
How the Other Steps Compare
Government Gateway account: same day
GB EORI: often minutes, up to a week when busy
CDS subscription: usually 2 hours, up to 5 working days if HMRC runs checks
The Simple Fix
Request the UTR on day one. Then run the quick steps while the letter is on its way. This one change keeps most registrations inside two weeks.
A Quick Check First
Companies should check their records before requesting a UTR, since they may already hold one from incorporation.
