Your Q1 2023 deadlines for the diary

We always aim to keep you up to date with the most pressing dates and deadlines for your business diary. To help you get prepared and on the ball, we’ve highlighted some of the forthcoming deadlines for Q1 of 2023.

NOTE: If your company’s accounting period is longer than 12 months, the first tax payment deadline is normally 21 months and 1 day after your accounting period started, and the second one is 9 months and 1 day after your accounting period ends.

For example, a company with an accounting period running from 01/06/2021 to 30/09/2022 will pay the first tranche of corporation tax by 01/03/2023 and the balance by 01/07/2023

If your profits are more than £1.5 million, then tax is payable quarterly with two payments before the end of your accounting period and two after. The first payment is normally six months and 13 days after the start of the period, with the others three-monthly from that point.

Some general deadlines to plan for:

• End of personal/payroll tax year: 5th April 2023, but practically speaking, for monthly payrolls the last one processed in the tax year is to 31 March 2023
• Enterprise Management Incentives Scheme notice of options granted: within 92 days of grant
• Final date to submit self-assessment tax return online for personal tax: 31 January 2023. Note: Making Tax Digital for Income Tax Self Assessment begins for self-employed businesses and landlords, as of April 2024. So, make sure your self-assessment process is ready for digital records and quarterly returns by 2024.
• Make Capital Gains Tax payment for 2021/22 tax year: 31st January 2023 (60 days after completion for gains re residential property)
• Make first payment on account for 2022/23 personal tax and balancing payment for 2021/22: 31st January 2023
• PAYE and National Insurance Payments due: 19th calendar day of the month after end of month or quarter as applicable (22nd for electronic payments)
