I've opened a UK company — what do I need to do next?
Forming the company is the easy part — staying compliant is the ongoing job. Here's what a brand-new UK company owner needs to set up in the first weeks, especially when you're based overseas.
What usually happens
Your company must have a valid registered office and an appropriate email address. Within roughly three months of becoming active you should register for Corporation Tax with HMRC. You'll have a confirmation statement and annual accounts due each year, and every director needs to verify their identity. Missing these is what leads to penalties and strike-off later.
What to check first
- 1
Set up a proper registered office (a London address with mail scan/forward if you're abroad).
- 2
Note your confirmation statement date and accounting reference date (year-end).
- 3
Register for Corporation Tax with HMRC within ~3 months of starting to trade.
- 4
Verify each director's identity and decide who keeps the bookkeeping.
- 5
Check whether you need to register for VAT or PAYE yet.
