How much does it cost to register a limited company?

There are different costs depending on which method you use to register (these are accurate as of January 2016):

  • Online applications cost £15, you can pay by debit or credit card or with a PayPal account.
  • Postal applications cost £40,  this is paid by cheque made out to ‘Companies House’ 
  • There is also ‘a same day service’; you must get your application to Companies House by 3pm, the cost for this is £100. Your envelope (and any courier’s envelope) must be marked ‘same day service’ in the top left-hand corner.
     

How long does it take to register a limited company?

  • Online applications are usually registered within 24 hours
  • Postal applications take between 8 – 10 days.

How do I update these details if they change?

You must tell Companies House about any changes to your limited company.

These changes might be:

  • directors and company secretaries, for example new appointments, resignations or changes to personal details
  • changing your company name
  • changing your registered office address
  • changing your accounting reference date
  • changing where your company records are kept, if this is different from your registered address
  • which records you’ll keep at an alternative address
  • changes to your company’s share structure, for example if you issue new shares.

Check on the Companies House website to see the full list of changes that need to be notified. You can update changes online via Companies House.

You will also need to tell HM Revenue & Customs (HRMC) of any changes. 

Do I need to register for Corporation Tax?

You need to register for tax within three months of starting to do business. ‘Doing business’ includes:

  • buying
  • selling
  • employing someone
  • advertising
  • renting a property.

If you register late you may incur a penalty.

To register you will need your business 10-digit Unique Taxpayer Reference (UTR). This will have been posted to your business address by HM Revenue and Customs (HMRC). This is usually usually within a few days of the company being registered with Companies House.

I’ve been working through the how to start a business in 20 days ebook and so many of the things I’d done are now nicely tied together and some gaps now filled. I love the simplicity. Thank you.
