The Chancellor of the Exchequer, Rachel Reeves confirmed, in a video message, that the next UK Budget will take place on Wednesday, 26 November 2025.

Details of all the Budget announcements will be made on a special section of the GOV.UK website which will be updated following completion of the Chancellor’s speech in November.

HM Treasury is inviting written representations for the Autumn Budget 2025 from individuals, interested groups, MPs and organisations. Submissions should propose evidence-based policy ideas or comment on existing policies, with clear rationale, costs, benefits, and deliverability. The deadline for submissions is 23:59 on Wednesday, 15 October 2025.

The Budget will be published alongside the latest forecasts from the Office for Budget Responsibility (OBR). This forecast will be in addition to that published for the Spring Statement and fulfil the obligation for the OBR to produce at least two forecasts in a financial year, as is required by legislation.

The OBR has executive responsibility for producing the official UK economic and fiscal forecasts, evaluating the government’s performance against its fiscal targets, assessing the sustainability of and risks to the public finances and scrutinising government tax and welfare spending.

Paying Corporation Tax? Always use the correct reference or risk delays and penalties.

To pay Corporation Tax via online or telephone bank transfer, you can use either a UK or overseas bank account.

UK Bank Accounts

You can transfer funds using Faster Payments, CHAPS, or Bacs, either online or by calling your bank. Faster Payments usually reach HMRC on the same or next day (including weekends), CHAPS payments arrive the same working day if made within your bank’s cut-off time, and Bacs payments typically take up to 3 working days.

Use the account details provided in your HMRC ‘notice to deliver your tax return’ or reminder. If unsure, use one of the following:

• HMRC Cumbernauld
  • Sort code: 08 32 10
  • Account number: 12001039
• HMRC Shipley
  • Sort code: 08 32 10
  • Account number: 12001020

Overseas Bank Accounts

You can also pay from an overseas account using:

• HMRC Cumbernauld
  • IBAN: GB62 BARC 2011 4770 2976 90
  • BIC: BARCGB22
• HMRC Shipley
  • IBAN: GB03 BARC 2011 4783 9776 92
  • BIC: BARCGB22

You must ensure to include your 17-character Corporation Tax payment reference number for the correct accounting period. This reference changes each year so it is important to use the up-to-date reference number. Using the wrong one can delay your payment. You can find it in your company’s HMRC online account or on your ‘notice to deliver your tax return’ or on any reminders from HMRC.

From 13 October 2025, access to Companies House WebFiling will require GOV.UK One Login. This replaces the older Government Gateway sign-in and is part of the wider move towards a single, more secure login across government services.

When you next log into WebFiling after that date, you will be prompted to connect your existing account to GOV.UK One Login. Without doing so, you will not be able to file company documents. This shift follows the earlier transition of the “Find and update company information” service in 2024.

The new login system provides additional benefits. It brings stronger security through two-factor authentication, reducing the risk of fraud and misuse. It also allows you to use one set of login details for multiple government services, cutting down on the need to manage different usernames and passwords. Over time, GOV.UK One Login will replace all other government login systems.

To prepare for the change, users should check that their WebFiling email address is up to date and accessible. If they also use the “Find and update company information” service, they should ensure both accounts use the same email address. It may be worth creating a GOV.UK One Login in advance using that same email. Companies House is also advising that users review and clean up their “My companies” list to remove any businesses they no longer file for.

Looking further ahead, identity verification becomes compulsory from 18 November 2025 for all new and existing directors and Persons with Significant Control. This can be completed voluntarily now via GOV.UK One Login or, alternatively, through an authorised agent.

In short, from mid-October WebFiling accounts must be connected to GOV.UK One Login. Preparing early will help avoid delays and ensure users are ready for the new identity checks that follow in November.

Running a small business comes with plenty to juggle, and while insurance might not be the most thrilling task, it is absolutely essential. There is one policy you are legally required to have: employers' liability insurance (EL). If you employ anyone, EL covers legal and compensation costs if someone falls ill or gets injured at work. Missing it could cost you a hefty £2,500 per day in penalties.

Beyond what is required, there are a number of other smart protections to think about:

• Public liability insurance (PL) protects against claims from members of the public, for instance, if someone has an accident at your premises or your team accidentally damages someone's property. Many clients or suppliers will require proof of this cover before doing business.
• Contents and portable equipment insurance covers your essential business gear, such as furniture on-site or gadgets you take out (laptops, tablets, smartphones), in case of theft, fire, flood, loss, or damage.
• Professional indemnity insurance (PI) is vital if you offer expertise or advice. It covers you if a client suffers a financial loss because of something you did or did not do. Many clients expect this sort of protection before hiring you.
• Directors’ and officers’ liability (D&O) protects company leaders personally if there is a claim against them, such as breaches of health and safety laws, pension mismanagement, or financial errors.
• Cyber liability insurance is increasingly important in the digital world. It helps cover the costs of data breaches or cyber-attacks, including claims, compensation, and even IT or legal support.
