In the News – What Business Owners Need to Know
Nearly time for the Autumn Budget
The Autumn Budget 2025 has been confirmed for 26 November 2025. Chancellor Rachel Reeves will share all the information in November and we would prefer to not speculate, we will share facts once we know the actual changes, we don’t take action on guesses, we wait for full details and then help you plan accordingly.
Jenners tip: If you’re a company director, investor, or you receive dividends or significant capital gains, now is a good time to review your structure you may want to model how different tax-scenarios could affect you. If you draw dividends, receive investment income, or are planning asset sales, it’s worth reviewing the timing before any policy changes are announced.
Companies House ID Checks begin 18 November 2025
From 18 November 2025, new identity verification rules come into effect for all company directors, People with Significant Control (PSCs), and those filing documents on behalf of a company. This is part of Companies House’s wider plan to improve transparency and prevent fraudulent company activity.
All individuals will need to verify their identity either directly through Companies House or via an authorised agent before they can act in these roles.
Good news: As we are a registered authorised agent, we can complete the identity verification process on your behalf — saving you time and ensuring everything is handled correctly. If you’d like us to take care of this for you, please get in touch with our team.

👉 Jenners tip: If you’re a director or PSC, don’t ignore the verification request it’s a legal requirement. Check the email or letter from Companies House carefully and complete the process early to avoid any filing delays or penalties.
Countdown to the Self Assessment Deadline
With only around 100 days to go until the online filing deadline for the 2024/25 tax year, HM Revenue & Customs is urging contractors, directors, landlords and other taxpayers to start gathering their records now. HMRC is encouraging millions of taxpayers to file their Self Assessment returns early this year, reminding everyone that the 31 January online filing deadline comes around quickly. Filing early gives peace of mind, avoids system slowdowns in January, and helps you budget for any tax owed.
Jenners tip: Start pulling together invoices, dividend vouchers, bank interest statements and CIS documents this month, the earlier you know your tax bill, the better your cash-flow planning. Don’t leave it too late gather your paperwork now so we can help you plan ahead.
Business Rates Back in the Spotlight
Proposals to increase property-based taxes have drawn criticism from retailers and hospitality groups, who warn that rate rises could lead to job losses. The government insists reforms are aimed at creating a fairer, more modern system. Industry bodies warn that proposed changes to business rates particularly for larger retail or hospitality sites may increase costs and put jobs at risk. For business owners this is a reminder that property tax remains a dynamic area of risk and opportunity.
Jenners tip: If your business leases, owns, or occupies commercial property, review your rateable value and contract terms now. Early dialogue with your adviser may uncover savings, or flag upcoming liabilities.
Simple Assessment letters: HMRC targeting bank/building-society interest
From October 2025, HMRC will start issuing “Simple Assessment” notices for tax owed on bank and building society interest where previously the full picture was not captured. This means taxpayers may receive additional tax bills for previous years if interest wasn’t included initially.
Jenners tip: Check whether you have received such a notice and review interest statements going back at least one year. Ignoring it could lead to surprise liabilities and penalties. If you’re unsure what to include, we can review this as part of your year-end preparation.
Review Your Cash Flow Before Year-End
With Christmas approaching and costs rising, November is a good checkpoint to review cash flow. Forecasting the next few months can help you plan for payroll, VAT, and tax payments with confidence.
Jenners tip: A quick forecast can highlight potential shortfalls and give you time to make smart financial decisions before year-end.
Client Q&A – This month’s Hot Topics
Q1: When should I start my Self Assessment if I haven’t yet?
A: Now. The earlier you start, the sooner we can identify any missing information and calculate your liability — avoiding January panic.
Q2: Will the Autumn Budget affect my 2024/25 return?
A: No — any tax changes announced will likely apply to future years. But early awareness helps with planning dividends, investments, and expenses.
Q3: I received a letter about extra tax on savings interest — what should I do?
A: Don’t ignore it. It’s part of HMRC’s new “Simple Assessment” process. Check your bank interest figures and contact us if you’re unsure what to do next.
Q4: Can I still offset CIS deductions against my tax bill?
A: Yes, CIS deductions count as tax already paid. Keeping accurate CIS statements ensures you don’t overpay and can claim what’s due.
