How VAT Payments on Account Work

Businesses owing over £2.3 million in VAT annually must make advance payments on account. These are based on the previous year’s VAT liability and paid in instalments. Late payments incur penalties, but adjustments may be possible for fluctuating liabilities.

The payments are usually based on the previous year’s VAT liability, and businesses are required to pay 1/24th of their estimated annual liability to HMRC by the last working day of the second and third months of the VAT quarter.

For example, if your VAT quarter ends on 31 March, your payments on account for that quarter will be due by 31 May and 30 June. Businesses that fail to make these payments on time will be subject to interest and penalties.

The payments on account and the balancing payments must be made electronically and cleared funds must be in HMRC's bank account by close of business on the due date. Businesses making POA do not benefit from the seven extra calendar days allowed to other VAT registered businesses for paying electronically.

The payment amount is calculated by HMRC based on the previous year’s VAT liability. If your liability changes and fluctuates by more than 20%, you may be able to request an adjustment to reduce your payments. This request must be approved by HMRC, and any adjustments will only be applied once HMRC has confirmed that the changes are valid. If the amount of VAT payable is higher than anticipated, the payment on account may increase, but it cannot exceed your total VAT liability from the previous year.
