Accounting methods
From the 2024 to 2025 tax year, the cash basis is the default way of doing your accounts. You must opt out if you want to use traditional accounting or if you can't use cash basis accounting.
With cash basis, you only record income and expenses when money comes in or goes out. This means you only pay Income Tax on the money you actually receive during your accounting period.
Registering for VAT
You must register for VAT if your turnover is over £90,000. You can register voluntarily if it suits your business, for example if you sell to other VAT-registered businesses and want to reclaim the VAT. Read guidance on VAT registration.
