What CATO’s closure means for small companies with simple tax affairs


The Government’s ‘Company Accounts and Tax Online’ (CATO) filing service allows small companies with the simplest affairs to file their company accounts and corporation tax return simultaneously with Companies House and HMRC. However, if you run a small business and use this service things are about to change.

The Government is closing the CATO portal on 31 March 2026. After that date, companies will no longer be able to file their company accounts and corporation  tax returns for free via CATO. You’ll need to either use commercial software or work with a professional accountant to do it for you. For the many micro‑entities and small companies that currently file on their own, this is a significant shift.

Some businesses may still be able to use a free web‑filing service from Companies House for micro‑entity or dormant accounts, but that only covers the filing of your statutory accounts – not your corporation tax return to HMRC – and that service is also expected to close in the near future. So, it makes sense to address both needs together when planning how you navigate the CATO closure.

Acting early to make life easier

Although CATO shuts on 31st March, many companies and their directors won’t feel the impact until months later, when their next filing deadline comes around. If you wait until that crunch point, you may find yourself:

  • choosing and learning new software under deadline pressure
  • hurriedly migrating or re‑entering data
  • settling for “whatever works right now”, even if it’s not a good long‑term fit.

And the reality is that all of these things increase the risk of making mistakes, filing incorrect data or even filing late, all of which could lead to penalties or in extreme cases being struck off.

If you usually use the Government’s free service and your filing deadline falls between now and 31 March, it’s business as usual for this year. Now is the time to start preparing for the transition. We recommend getting your filings in as early as possible this year to avoid a last-minute rush. This also gives you the space to begin exploring how a professional accountant or bookkeeper can support your business through these changes. Preparation is the key to a successful, stress-free transition next year.

If your filing deadline falls not long after the 31st March, say April, May or June then it would be worth giving some thought, if practical, to trying to file a little earlier this year in order to avoid rushed decisions. If you could file before the 31st March in order to utilise CATO then you’ve effectively bought yourself  a year to make the right long term decision that’s the right strategic fit for you and your business. This isn’t going to be possible in all cases but it’s certainly worth thinking about!   

Regardless of how or when you plan to file your next set of accounts and tax return, the Government is encouraging all CATO users to ensure they download and save all their previously submitted accounts and tax returns via the portal before it closes. After the 31st March you won’t be able to access your historical submissions and you may find you need them in the future. The government has provided instructions on how to do this here.

Why an accountant or bookkeeper is still best practice

For many small businesses, the best route through this change will be to work closely with an accountant or bookkeeper. They can:

  • guide you through software choices and setup
  • help you understand whether your affairs really are “simple enough” to keep doing it yourself or whether it’s time to get expert help from a professional
  • advise on the most suitable approach for your size and sector
  • make sure your bookkeeping, accounts and tax all join up smoothly.

The right software choice and set up coupled with good digital record keeping throughout the year can lead to a streamlined, stress free year end process that’s more about review and approval than last minute data entry, re-keying of data and stressful reconciliations. An experienced advisor can design and run that system with you, as hands on or as hands off as needed, so you stay compliant and confident without needing to become a tax or software expert yourself.

Whilst CATO’s closure is undoubtedly frustrating for many, it’s also a timely reminder to take a step back and make sure your whole set up and year‑end process is fit for the future. Take the opportunity now to talk to an accountant or bookkeeper and put a simple, joined-up plan in place – so when the portal disappears, you’re already one step ahead.

When evaluating the health of a small business, we typically focus on financial indicators: revenue, margins, expenses, and growth trajectory. But Xero’s Emotional Tax Return 2026 report highlights another critical metric – the psychological cost.

U.S. small business owners lose an average of 33 working days per year to stress. That’s more than a month of lost productivity, driven not only by market conditions but by the sustained mental load of managing cash flow, compliance, rising costs and daily financial decisions.

From a financial therapy perspective, this is not surprising. But what stands out most is how persistent this financial stress has become.

Why avoidance is common – and predictable

The report reveals a pattern many small business owners will recognize:

  • 73% have been caught off guard by a tax outcome
  • 34% fear making financial mistakes
  • Owners lose an average of eight hours per week to stress

Avoidance is often misunderstood as poor discipline. In reality, it is a common psychological response to perceived threat. When systems feel fragmented or unclear, financial tasks can trigger anxiety. Choosing to disengage reduces discomfort temporarily, but it allows the uncertainty to compound.

When financial visibility is low, stress increases. And when stress increases, decision-making quality declines. Reducing small business stress requires addressing that cycle directly. Stress, in this context, is not only a mental health issue. It is an operational constraint that affects small business productivity.

When financial stress becomes structural

According to the report:

  • 70% of owners say financial management is a major stressor
  • 81% say this fiscal year has been more stressful than previous years
  • 74% report stress negatively affects their professional performance

That strain shows up in missed opportunities (34%), slower decision-making (28%) and reduced creativity (30%).

In clinical practice, I often see how chronic financial stress narrows cognitive bandwidth. When uncertainty around cash flow, tax obligations or operating expenses becomes constant, the brain shifts into threat mode. Attention tightens. Working memory declines. Over time, this doesn’t just feel exhausting. It becomes limiting.

Financial visibility reduces perceived threat

One of the most effective stress-reduction strategies in financial therapy is increasing perceived control. Control does not mean eliminating uncertainty entirely. It means improving clarity within what can be managed.

This is where a platform like Xero plays a crucial role. Real-time dashboards, automated bank reconciliation, integrated reporting and digital receipt capture centralize financial data and reduce manual workload. Instead of chasing paperwork or reconciling transactions late at night, business owners can access up-to-date cash flow information in one place.

Eighty-seven percent of U.S. customers say Xero improves financial visibility. Ninety percent say it helps their business run more efficiently.

From a psychological standpoint, improved visibility reduces threat activation. When business owners can clearly see what’s coming in, what’s going out and what’s due, decision-making becomes proactive rather than reactive.

Bookkeeping automation protects mental bandwidth

The average small business owner spends 22 hours per month managing finances. That’s nearly three full workdays devoted to admin. Automation meaningfully reduces that burden. Businesses using Xero save an average of six hours per week on bill management alone.

Those hours add up. But more importantly, so does cognitive relief. Less manual data entry. Fewer surprises at tax time. Fewer last-minute reconciliations. The result is not just greater efficiency, but stronger cash flow management and better long-term planning.

When administrative friction decreases, small business productivity improves – and so does wellbeing.

Collaboration reduces isolation

Despite the documented impact of financial stress, only 9% of small business owners seek advice from an accountant or advisor as a coping strategy.

Isolation intensifies pressure. Collaboration diffuses it.

Real-time collaboration features allow business owners and advisors to work from the same live financial data. That reduces errors, improves forecasting and increases confidence. For the 34% who fear making financial mistakes, shared visibility offers both technical accuracy and emotional reassurance.

In my experience, financial clarity combined with trusted guidance is one of the most powerful antidotes to chronic financial stress. It transforms financial management from a solitary burden into a supported system.

Turning emotional tax into resilience

Forty percent of small business owners report having considered giving up their business. That statistic underscores the broader economic implications of sustained financial stress.

Entrepreneurship will always involve risk. But persistent, preventable financial stress does not need to be part of the model.

Reducing the Emotional Tax starts with structural shifts:

  1. Improve real-time financial visibility
  2. Automate repetitive bookkeeping and admin
  3. Collaborate proactively with financial advisors

When business owners can clearly see their numbers, anticipate obligations, and reduce manual workload, they regain more than time. They regain perspective.

The Emotional Tax is measurable. But so is the return when clarity replaces uncertainty.

And when clarity returns, confidence follows – not just in the numbers, but in the long-term health of the business itself.
