DIY Accounting

If you work through your own limited company, it can be tempting to think about doing your accounts yourself. But should you? If you're thinking about DIY accounting, we've put some information together to help you decide.

Let's talk

Can I do my own company accounts?

There is no requirement to have a professional do your accounts, and you are well within your rights to do them yourself. Some things to consider are:

How much time do you have to dedicate to doing your accounts?

In order for you to be able to successfully manage your finances, you should be able to dedicate around 15 minutes each day. For busy contractors, it can be a challenge to balance this alongside work.

How much do you know about doing your accounts?

While you don't need to be a trained professional to manage your own company numbers, you do need an understanding of bookkeeping and finance. If you make a mistake or miss a deadline, HMRC won't be lenient.

What can an accountant do for me?

Providing an accountancy service involves far more than simply checking invoices and receipts, and then filling in a tax return form once a year. A good accountant will provide ongoing, proactive advice throughout the year and not just at the end when it will probably be too late to save you from an excessive tax bill. And in order to do this, they have to keep abreast of the UK tax system and all of its regulations and legislative changes.

An accountant should:

  • Help you to structure your company in the most tax-efficient way possible
  • Help you to understand the best way to take money out of your company
  • Understand what you can claim by way of expenses and the impact on your income and taxes
  • Help you to understand all of your tax liabilities both personal and corporate. These include:
    • Employer's National Insurance contributions
    • Employee's National Insurance contributions
    • Personal income tax
    • VAT (Flat Rate Scheme or standard VAT)
    • Corporation Tax
  • Prepare and complete your personal Self-Assessment Tax Return each year
  • Understand when, how much and where to send a payment for all taxes that are due
  • Explain the benefits of not taking every penny out of your company along with other tax planning opportunities

Poor tax planning, or even worse no tax planning, can lead to any number of financial difficulties - such as an overdrawn directors loan account, financial penalties due to late or incorrectly submitted tax submissions, incurring additional tax for things that are classed as ‘benefits in kind’ and so on. The list is endless.
