As a small business owner operating in the UK, it is important to stay on top of accounting and tax dates in order to ensure compliance and avoid penalties from HMRC or the companies house.

Below are the key dates to note, including examples for each:

1. Self-Assessment Tax Return (for Individuals, Sole Traders, and Partnerships)

Filing Deadline (Paper): 31 October following the end of the tax year.
Filing Deadline (Online): 31 January following the end of the tax year or 30 December to be eligible (if other conditions are met) for paying tax through the PAYE tax code.
Payment Deadline: 31 January following the end of the tax year for balancing payment and first payment on account. The second payment on account is due on 31 July.
Example: For the tax year ending 5 April 2024:
- Paper filing deadline: 31 October 2024
- Online filing deadline: 31 January 2025
- Payment deadlines: 31 January 2025 (first payment) and 31 July 2025 (second payment)

*Tax year is a 12 month period which runs from 6 April to the following 5 April.

*Class 2 & 4 NICs are paid via Self Assessment by 31 January following the end of the tax year.

*An accounting period is a duration for reporting accounting functions. It is not necessarily from January to December and could also be longer in the first year of incorporation. The accounting period affects the deadline for filing accounts, corporation tax return filing and payment.

Never miss a deadline again!

Remember to mark these on your calendar to ensure compliance.

Tips:

Where the deadline falls on a weekend or bank holiday, the submission or payment is still required by that date.
Corporation tax payment is due before the tax return submission. However, the tax return should be prepared in order to determine the corporation tax due for payment.
