If your personal tax bill for the year ended 5th April 2022 exceeds £1,000, you will likely be required to make payments on account of the year ended 5th April 2023. This will be made up of half your future tax bill upfront in January 2023, and another half in July 2023. This means that by the 31st July 2023, you should have paid HMRC the equivalent tax for the year ended 5th April 2023, as you did for the year ended 5th April 2022.
