Cash accounting is available if your VAT taxable turnover is £1.35 million or less, and you can use it to improve cash flow by delaying VAT payments.

Invoice accounting is mandatory if turnover exceeds £1.35 million, and it provides consistency but may require upfront VAT payments.

With cash accounting, you only account for VAT when cash is received or paid, which can benefit businesses with slow-paying customers.

With invoice accounting, VAT is accounted for on invoice dates, so you might pay VAT before receiving payment, impacting liquidity.

You can switch from cash to invoice accounting if your turnover grows, but HMRC approval may be needed for changes.

Cash accounting simplifies record-keeping as you track actual payments, reducing errors for small businesses.

Invoice accounting requires careful tracking of invoice dates, which is essential for Making Tax Digital (MTD) compliance.

For VAT returns, cash accounting uses payment dates, while invoice accounting uses invoice dates on your VAT return submissions.

Bad debts are handled differently: under cash accounting, no VAT is due on unpaid invoices; under invoice accounting, you may need to adjust for bad debt relief.

Choosing the wrong method can lead to penalties, so consider your business model, customer payment terms, and cash flow needs.
