Company tax returns and accounts have gone digital

HMRC and Companies House have confirmed that from 1 April, all businesses must use compliant, commercial software to file their company’s tax returns.


As of 31 March, the free joint online service, commonly known as the CATO portal, from these two Government bodies has been removed and you must now use software to file company tax returns to HMRC.


For the time being, you will still be able to file annual accounts at Companies House using third-party software, WebFiling services or paper filing.


The decision has been made to end this service as it is “outdated and no longer aligns with modern digital standards”, according to Companies House.


This change is in line with the introduction of the Economic Crime and Corporate Transparency Act, which implemented “enhanced corporation tax requirements and changes to UK company law.”


It also follows on from a major IT security breach at Companies House, identified in March 2026, that exposed the WebFiling system and allowed some users to potentially access and amend the details of other companies.


Although the breach has now been resolved and security strengthened, it has raised concerns about the reliability of GOV.UK One Login service.



Can you still amend previous returns using the free service?


HMRC and Companies House have confirmed that now that the free filing service has closed, company directors will have to use commercial tax software if they need to make changes to a previously submitted Corporation Tax return or refile a rejected return.


From now onwards, any previously filed financial information will no longer be available in the system, as it has not been retained and will need to be entered again.

HMRC has said that, for amendments, it will also be acceptable to send a paper return to the Corporation Tax Services office.


If you have previously filed financial accounts with Companies House and you want to make changes or corrections, this will also need to be done via commercial software or by sending paper accounts to Companies House via post.


Are there any exceptions to this new rule?


Companies can file a paper Corporation Tax return only in limited circumstances, such as if they wish to submit it in Welsh or can demonstrate a valid, reasonable excuse to HMRC. Otherwise, returns must be filed online using commercial software.


If you are affected by this change and need help choosing and utilising commercial software to complete your Corporation Tax return, please speak to our team. 

Are your finances at risk of cyber-attack? Planning for the worst

By Charlie Flockhart • October 5, 2026
According to the latest Hiscox Cyber Readiness Report, almost two in five small businesses in the UK suffered a successful cyber-attack in the last year, with each attack costing an average of £26,650. Globally, cyber incidents cause around 32 hours of operational disruption a year on average. Cyber-attacks are no longer exceptional events, being viewed more as recurring costs, so businesses must prepare themselves financially for the impact. How should you prepare your finances in advance of a cyber-attack? A cyber-attack is slowly and sadly becoming a reality for many SME owners across the UK. To prepare, business owners should assess the potential financial risk a cyber-attack poses and forecast cash flow to ensure their business can survive one. It could also be beneficial to value your data assets to estimate the worth of any lost revenue and recovery expenses. Business owners may also want to keep offline playbooks. These are secure, printed offline copies of critical financial contacts, account numbers and recovery protocols to ensure that your business has key information in the event of a cyber-attack. Additionally, your business should establish strict double-check procedures for unusual payment requests or changes to supplier details to prevent business email compromise. You should also factor cyber insurance premiums into your operational risk management to ensure that you are prepared for any eventuality. What should you do to get your finances back in check after a cyber-attack? Should the worst-case scenario happen, once you are back on track, the first thing you should do is speak with your accountant. Your accountant will help you to calculate the exact monetary value of damaged assets, lost revenue and stolen money so that you know exactly where your business stands. They will then review your financial data and your tax records to establish a baseline for recovery and determine if the business can continue or if restructuring is necessary. Accountants can also help during complex cyber insurance claims by submitting the required evidence to ensure fair financial assessments of the business interruption costs. Once you have received any insurance payments, an accountant can advise on the tax implications.  How can we help? Cyber-attacks are becoming more prevalent for businesses up and down the UK. That is why it is imperative that you receive advice on how you can best prepare your finances in a worst-case scenario. Our team of accountants can help you to prepare your business for a cyber-attack and in the event of a cyber-attack, we can help you pick up the financial pieces.

Borrowing amongst SMEs is on the rise – preparing your business for finance

By Charlie Flockhart • October 5, 2026
According to UK Finance, gross lending to SMEs from the main high street banks reached £5.35 billion in the second quarter of 2026, the highest quarterly level recorded since the pandemic. Real estate and professional service firms drove much of this growth, while manufacturers and hospitality businesses borrowed less. How can loans help SMEs? A loan can often be a lifeline for SMEs in a financial rough patch. It can help a business bridge cash flow gaps in the short term, ensuring that it has enough money to cover payroll, rent and supplier obligations. It could also be the case that a loan can help to fund expansion to increase business opportunities or hire more staff. Additionally, loans can help business owners to retain ownership of the company rather than selling equity to investors. However, SMEs need to remember that a loan must be paid back with interest regardless of business performance. How should SMEs prepare for a loan? Preparing your business for a loan can often be a tricky process. First, you will need to gather two to three years of profit and loss statements alongside cash flow forecasts and up-to-date tax filings. Next, you will have to check and correct any errors that may be on your personal or business credit reports in order to optimise your credit profile before borrowing. You will then have to create a strong business plan outlining your core growth strategy and market opportunity. There should be a clear breakdown of how the funds will be used, linking every borrowed pound to revenue generation, as well as a risk mitigation section addressing potential economic downturns. You must consider the lender that you are selecting by comparing criteria across high street banks and alternative providers.  How can an accountant help? An accountant can be one of your most valuable assets when applying for finance. They can help to improve your financial record-keeping, build advanced financial models and stress-test your cash flow to give lenders greater confidence in your business. We understand that it is tough for SMEs to obtain funding at the moment. That is why our team can help you obtain the loan that you need.

Medium-sized companies may qualify for audit exemption

By Charlie Flockhart • October 5, 2026
The Department for Business, Innovation, Science and Trade (DBIST) initiated a ‘modernising corporate reporting’ consultation on 7 September 2026, which closes on 30 November 2026. Under the proposed overhauls, many medium-sized companies may be exempt from mandatory audits. This consultation forms part of a wider Government pledge to cut administrative burdens on businesses by 25 per cent by 2029. What is being proposed? The Companies Act 2006 considers various company size categories to assess which reporting, audit and disclosure requirements apply. For medium-sized businesses wanting to access exemptions currently exclusive to small companies, they must not exceed two of the following three thresholds: Turnover of £54 million Balance sheet total of £27 million Average of 250 employees Under these exemptions, many businesses would no longer need to have an audit, provide cash flow statements or prepare consolidated accounts. Elsewhere, the proposals from DBIST include: Introducing an SME accounting standard Allowing companies to calculate employee numbers on a full-time equivalent basis Removing strategic report requirements for most medium-sized private companies Simplifying financial reporting rules Is it always smart to forgo an audit? While the proposals mean audits may become optional for some SMEs, forgoing an audit isn’t always the smartest move. An audit can often go one step further than simple compliance and financial reporting, providing insights and peace of mind that your numbers are accurate. Lenders also often rely on audited accounts when deciding how much to lend and at which interest rate. Likewise, when it comes to selling a business, buyers and investors often look at audited figures when conducting due diligence as they offer greater credibility. For any businesses mulling the exemption, it is important to evaluate long-term plans and whether spending money on an audit could have benefits. At the moment, these changes are part of an ongoing consultation and so may be subject to change in future. We will bring you further updates as they emerge. Speak to an accountant to evaluate whether an audit may be beneficial to your business.
