The job that costs you when it slips
Setting up a company at Companies House is only half the job. HMRC still needs to be told the company is active, normally within 3 months of trading, and getting your accounting dates and first period right at this stage saves a lot of confusion later.
Plenty of founders miss this step entirely, then face penalties and a messy first tax year. Others set the wrong dates and end up with overlapping or unexpectedly long periods. It is the kind of thing that is easy to get right at the start and painful to fix afterwards.
- Assuming incorporation already registers you for tax
- A 3-month deadline that is easy to miss
- Accounting dates set wrongly from day one
- Penalties for telling HMRC late
- Needing PAYE and VAT registration as well
- A confusing, overlapping first accounting period
Hand it over, and consider it handled
When a limited company starts to trade, it must register for Corporation Tax with HMRC, usually within 3 months of becoming active. Although Companies House issues a UTR on incorporation, you still have to tell HMRC the company is active and provide details about the business and its accounting period.
We handle the registration for you, make sure your accounting reference date and first period are set correctly, and explain your Corporation Tax deadlines so the first year does not catch you out.

The honest answers to what you’re thinking
Can I not register myself on the HMRC website?
You can, if you are confident about your start date, business activity and how to set your accounting period. We do it correctly, set your dates to suit you, and map your deadlines, so your first year runs cleanly.
Is this not included when I form a company?
Not by default. Forming a company and registering for Corporation Tax are separate steps. We can do both together, or just the registration if your company already exists.
I think I am already late, what now?
Contact us and we will register you right away and help minimise any penalties. The sooner it is sorted, the better.
Do I definitely need this if I have not made any money yet?
If the company is genuinely dormant and not trading, you may not need to register yet, and we can confirm that. Once it becomes active, the 3-month clock starts and registration is required.
