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
What we do

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.

FAQ

Corporation Tax Registration questions, answered

Do I need to register for Corporation Tax if my company is already at Companies House?
Yes. Incorporation gives you a company and a UTR, but it does not register you for Corporation Tax. You must separately tell HMRC the company is active, normally within 3 months of starting to trade, and we handle that for you.
When does the 3-month clock start?
It starts when the company becomes active, which usually means when it starts trading, buying, selling, employing or otherwise doing business. We work out your date and register in good time.
What happens if I miss the deadline?
Late registration can lead to penalties and a tangled first tax year. If you are already late, we register you straight away and get your position back on track.
Can you register me for PAYE and VAT at the same time?
Yes. New companies often need more than one registration. We handle Corporation Tax, PAYE and VAT registration together so the whole setup is done once and done right.
What is a UTR?
A Unique Taxpayer Reference is the 10-digit number HMRC uses to identify your company for tax. Companies House passes your details to HMRC and a UTR is issued after incorporation; we use it to register you for Corporation Tax.
