Sole Trader vs Limited Company Which Is Better?
According to Companies House's own figures, just 2.86% of directors and people with significant control who were required to complete the new mandatory identity verification had actually done so by the point the government felt compelled to publish the number. That's not really a story about defiance. It's a story about how easy it is to fall behind on company obligations that keep quietly multiplying, especially when you're genuinely focused on running your business rather than tracking every regulatory change affecting it.
I get asked "do I actually need an accountant?" more often than almost any other question, usually from a director who's just incorporated and is trying to keep costs down in the early days. It's a completely reasonable question, and the honest legal answer is: no, there's no law requiring a limited company to use one. But "legally required" and "genuinely sensible" are two very different tests, and 2026 in particular has made the gap between them wider than it's been in years. Let's go through exactly what you're on the hook for, what an accountant actually handles, and where doing it yourself stops being a sensible saving and starts being a genuine risk.
I think of a client, the director of a small events management company near Southborough, who incorporated his business himself, filed his first confirmation statement himself, and genuinely managed perfectly well for the first eighteen months without any real trouble. What eventually brought him to us wasn't a disaster — it was simply the accumulating weight of obligations that had grown considerably more complex than the simple company he'd originally pictured: he'd taken on his first employee, crossed the VAT threshold without quite realising it, and then found himself facing the new identity verification requirement with no real idea where to start. None of it was individually catastrophic. Together, it was more than he wanted to keep managing alone, and he told me afterward that he wished he'd made the switch a full year earlier than he actually did.
Every limited company must file a confirmation statement at least once every 12 months, confirming key details about the company — including, as of 2026, a full list of shareholders rather than just changes since the last filing. The digital filing fee rose to £50 from 1 February 2026, with paper filing now costing considerably more at £110, a deliberate nudge toward digital filing.
The bigger change for 2026, though, is identity verification. Every director and person with significant control is now required to formally verify their identity with Companies House, either directly through GOV.UK One Login or via an Authorised Corporate Service Provider. This isn't optional paperwork you can quietly ignore: a confirmation statement will now be rejected outright if even one director hasn't completed verification and provided their personal code. Existing directors have had a transition window running through much of 2025 and 2026 to get this done, tied to their confirmation statement date, but enforcement action against those who haven't complied is expected to begin by the end of the year. Given that barely 3% had completed it at one recent checkpoint, this is genuinely worth checking today, not filing away as a someday task.
Beyond the confirmation statement, every company must also file statutory annual accounts with Companies House, generally within nine months of your company's year-end. Miss it, and penalties start at £150 for accounts filed even a single day late, rising to £375, then £750, then £1,500 the longer the delay continues — and the penalty doubles if you're late two years running. Persistent non-filing can ultimately lead to the company being struck off the register entirely.
It's worth being honest about how much has changed here in a single year. A director who confidently handled their own Companies House compliance in 2024 or 2025 is now navigating a genuinely different process — verification steps, personal codes, and rejection risk that simply didn't exist before. This isn't a case of the rules becoming marginally more complicated; for many directors, it's the first genuinely new compliance hurdle they've faced since incorporating, and it's landed at a moment when Companies House's own enforcement approach is still being worked out in real time.
Separately, you must register for Corporation Tax with HMRC within three months of starting to trade — a deadline that catches out more new directors than you'd expect, since it's easy to assume incorporation and tax registration are the same step when they genuinely aren't. You then need to file a Company Tax Return, the CT600, within 12 months of your accounting period ending, though — and this trips people up constantly — the actual Corporation Tax payment is due considerably earlier, nine months and one day after your accounting period ends. If you employ anyone, including yourself as a director drawing a salary, you need to operate PAYE correctly, submitting Real Time Information to HMRC every pay period. And once your taxable turnover crosses £90,000 in any rolling 12-month period, VAT registration becomes compulsory, with quarterly returns to follow.
None of this is impossible to manage yourself. All of it needs to be done correctly, on time, and it genuinely adds up to more ongoing obligation than most first-time directors expect when they first picture "running a small company." I'd add, too, that HMRC's penalty regime for late Corporation Tax payment compounds in a similarly unforgiving way to the Companies House one — interest accrues from the payment date regardless of when the return itself is filed, which catches out directors who assume, reasonably but wrongly, that the twelve-month filing deadline and the nine-month payment deadline are the same thing.
Preparing statutory annual accounts to the correct standard, formatted properly for Companies House and HMRC, is core accountant territory. Get the format or the figures wrong, and you risk rejection, delay, or — worse — an inaccurate set of accounts that then feeds into an incorrect tax return, compounding a single mistake across two separate filings.
Calculating your Corporation Tax liability correctly involves more than applying a flat percentage to your profit. Capital allowances, allowable expenses, R&D relief where genuinely applicable, and the marginal relief calculation for profits between £50,000 and £250,000 all affect the final figure, and getting any of them wrong means either overpaying tax you didn't need to, or underpaying and risking a later HMRC correction with interest attached. Most directors have no reason to know these rules in detail — that's precisely what the qualification behind a good accountant is for.
Running PAYE correctly — accurate payslips, correct tax codes, timely RTI submissions, and pension auto-enrolment compliance — is a genuinely detailed, deadline-driven task that most directors underestimate until they're the one responsible for it. Get it wrong and the consequences fall on your employees as much as on you, which makes this an area where professional handling tends to be worth it even for a very small team. I've seen directors genuinely surprised by how much ongoing attention payroll requires — it isn't a set-and-forget system, and even a modest change like a pay rise or a new starter needs handling correctly every single time.
This is where 2026's changes have shifted the calculation meaningfully. A qualified accountant, registered as an Authorised Corporate Service Provider, can handle your Companies House filings — including the identity verification process — on your behalf, navigating the new requirements properly rather than leaving you to work through an unfamiliar system alone during a year when even Companies House's own enforcement approach is still bedding in. Given how many directors were still behind on verification at the most recent check, having someone whose job it is to track these deadlines has become genuinely more valuable this year than in previous ones, and it's worth confirming directly that any accountant you're considering is genuinely ACSP-registered before you rely on them for this.
Registering at the right time, choosing the most appropriate VAT scheme, and filing accurate quarterly returns — increasingly under Making Tax Digital requirements — is another area where an accountant's ongoing oversight prevents the kind of quiet drift that leads to a backdated registration and an unwelcome penalty. A modest amount of regular attention here tends to be all it takes to avoid the problem entirely, which is exactly the kind of low-effort, high-value oversight an ongoing accountancy relationship provides almost as a byproduct.
Yes, entirely legally. Plenty of very small, simple limited companies are managed successfully by directors doing their own bookkeeping, using accounting software to prepare accounts, and filing everything themselves. I wouldn't want this guide to suggest otherwise, because it genuinely isn't true. What I would say, honestly, is that the number of businesses for whom this remains the right long-term choice tends to shrink as the company's affairs — and, as of this year, the compliance landscape itself — grow more complex.
The honest test I'd suggest applying to yourself is this: are you confident you'd notice if something changed in the rules that affected you? For most of the directors I meet who manage everything themselves successfully, the answer is genuinely yes — they read the relevant updates, stay on top of deadlines, and treat compliance as a genuine, ongoing responsibility rather than an afterthought. For those where the answer is honestly "probably not," that's less a judgement on their competence and more a sign that their time is better spent running the actual business than tracking regulatory change.
The £90,000 threshold is based on rolling 12-month turnover, not your accounting year, which means it can be crossed mid-year without anyone noticing until it's already happened. I've seen more than one director discover this months after the fact, facing a backdated registration and a penalty that a modest ongoing accountancy fee would have avoided entirely. It's precisely the kind of threshold that a busy director, focused on winning work rather than watching a rolling turnover figure, can genuinely miss.
The moment PAYE enters the picture, the margin for error narrows considerably, and the consequences of getting it wrong land on someone other than just you. This is, in my experience, one of the most common points at which a previously DIY director decides it's time to bring in proper support — not because they've done anything wrong yet, but because they can see clearly how much more there now is to get right.
As covered above, 2026's identity verification and ACSP requirements have genuinely raised the bar for what "doing your own Companies House filings" now involves. A director confident filing a simple confirmation statement a year ago may find the process now includes verification steps, personal codes, and rejection risk that didn't exist before — precisely the kind of shifting regulatory ground where professional support earns its fee. Given that a rejected confirmation statement can, if left unresolved, escalate toward strike-off proceedings, this isn't a corner worth cutting purely to save a modest ongoing fee.
Being genuinely represented by a qualified, regulated professional during an HMRC compliance check tends to produce a considerably smoother, less stressful process than managing it entirely alone — particularly if the enquiry touches on judgement calls, like whether an expense was genuinely allowable, where professional experience makes a real difference to the outcome. Facing this kind of correspondence for the first time, with no professional support and genuine uncertainty about how seriously to take it, is one of the more stressful experiences a director can have, and it's precisely the moment DIY compliance tends to feel like the wrong choice in hindsight.
A few honest signals worth taking seriously: you're genuinely unsure whether you're claiming everything you're entitled to; you've missed, or nearly missed, a deadline in the past year; your accounting software throws up numbers you don't fully understand; or you've simply started dreading the admin rather than managing it comfortably alongside running the business. Any one of these is a reasonable moment to bring in proper help, rather than waiting for a genuine mistake to force the decision.
A small limited company's full accountancy support — annual accounts, Corporation Tax, and Companies House compliance — typically runs from £800 to £2,000 a year, rising with complexity, payroll, and VAT involvement. Doing it entirely yourself costs no direct fee, but it costs genuine time — often considerably more than directors initially estimate, particularly once identity verification, RTI payroll submissions, and quarterly VAT are all factored in — plus the real, if harder to quantify, risk of an error, a missed deadline, or a rejected filing costing considerably more than the fee would have. We've covered accountancy pricing in full detail in a separate guide on this site, but the short version is this: for most limited companies beyond the very simplest, the fee tends to be considerably cheaper than the cost of getting something wrong.
It's worth genuinely valuing your own time in this calculation too, not just the risk of error. A director spending several hours a month on compliance admin that could be handled properly, and faster, by someone qualified to do it, is a director spending less time on the parts of the business that actually generate revenue. That trade-off is easy to overlook when the accountancy fee is the only cost that shows up on a bank statement.
We work with limited company directors across Tunbridge Wells, Tonbridge, Sevenoaks, and the wider South East, and 2026's Companies House changes have made this an unusually good year to have that conversation, if you haven't already. As an ACSP-registered firm, we can handle your identity verification and Companies House filings alongside your accounts, Corporation Tax, and payroll — all under one roof, so you're not left navigating an unfamiliar new compliance regime on your own during a year when even the regulator's own enforcement approach is still settling in.
We understand, too, that plenty of directors reading this genuinely have been managing everything themselves successfully, and that's a perfectly reasonable position to be in. We're not here to tell every director they need us. We're here to give you an honest read on whether your specific business, at its specific stage, still benefits from doing it entirely alone — and if it does, we'll tell you that plainly rather than manufacturing a reason for you to sign up regardless.
If you're a director currently managing everything yourself and wondering whether that's still the right call, we'd be glad to talk it through honestly — including telling you plainly if your current approach genuinely still works fine. Get in touch with us to find out where you stand.
