HMRC's Tax Update 2026 and the Bank Account Gambit: What Every Compliance Practice Must Do Before August

31 July 2026. Mark it. That is the second Self-Assessment payment on account deadline, and this year it arrives alongside the most consequential package of HMRC reform proposals in a generation.

On 23 June, the government launched what it is calling Tax Update 2026: forty measures spanning simplification, modernisation, and fairness. ICAEW describes it as containing significant changes, and for once the understatement is doing real work. The headline that will concentrate minds in every practice from Truro to Edinburgh is a proposal to allow HMRC to recover low-value tax debts by deducting instalment payments directly from a taxpayer's bank account, without requiring a court order. The consultation document is live. The policy intent is not ambiguous.

What HMRC Actually Proposed on 23 June

The bank account debt recovery proposal applies to customers who can pay but have not responded to multiple contact attempts from HMRC. A separate but related consultation proposes requiring PAYE and VAT liabilities to be paid by direct debit. Taken together, these two measures represent a structural shift in HMRC's enforcement posture: from persuasion to automated extraction.

Also in the package: a proposed criminal offence for reckless untrue declarations or reckless false statements in direct tax matters, aligning the direct tax framework with powers that already exist for indirect tax. HMRC also proposes to reform its Publishing Details of Deliberate Defaulters policy, raising the threshold for publication to £50,000 potential lost revenue while simultaneously broadening what it can publish about non-compliant taxpayers. The government has, in the same breath, announced a comprehensive review of the end-to-end customer journey for small businesses, examining how firms interact with HMRC across their lifecycle. One hand soothes. The other reaches for the wallet.

For accounting and legal practices advising owner-managed businesses, the bank account proposal demands immediate client communication. The 31 July payment on account deadline is the obvious prompt. Clients who are habitually slow to engage with HMRC correspondence need to understand that the tolerance window is closing, and that the next logical step beyond a penalty notice may be a direct deduction from their current account.

What This Means for Your Monday Morning

Three things require action this week:

First, review your client base for outstanding HMRC correspondence. The direct debt recovery proposal targets those who have ignored multiple contact attempts. If you have clients in that category, they need a call before they need a letter from HMRC.

Second, check whether any accounts were caught in the Companies House outage of 12–16 June. A technical issue closed webfiling, software filing, and company incorporation services for four days. Companies House has confirmed that filing deadlines missed due to those service issues will generate late filing penalties, but that they can be appealed. If a filing deadline was missed during that window, file immediately and preserve a record of the date and time you attempted to access the service. The appeal mechanism is online. Use it.

Third, revisit your ACSP registration status. Third-party agents will only be able to file Companies House documents if they are registered as Authorised Corporate Service Providers. That requirement, originally expected in Spring 2026, has been pushed back to no earlier than November 2026. The delay is welcome. It is not a reprieve. November is not far away, and registration takes time.

The Identity Verification Ratchet

Companies House identity verification enforcement is entering a new phase. From 18 November 2025, IDV of directors and PSCs became a mandatory obligation. Companies House has now published its enforcement strategy, and the architecture is worth understanding.

Enforcement operates through four broad categories: education and engagement first, then reminders tied to confirmation statement filing deadlines, then civil financial penalties, and finally criminal prosecution under the Companies Act 2006 for deliberate evasion or fraudulent activity. The threshold for prosecution is three or more offences in a five-year period, use of fraudulent identity documentation, or evidence of criminal activity. What the guidance makes clear is that even inadvertent non-compliance is likely to attract consequences. The transition period was never an amnesty. It was a runway, and it is shortening.

For professional services firms managing IDV on behalf of clients, the practical risk is transactional. Delays to deals, challenges to corporate authority, and adverse due diligence findings can all flow from poor identity verification compliance, particularly as enforcement activity ramps up from the end of 2026. An incomplete IDV record discovered during M&A due diligence is the sort of problem that generates fee write-offs and uncomfortable partner conversations in equal measure.

The Formation Data: A Market Under Pressure

Against this backdrop of escalating compliance burden, the company formation market is telling an interesting story. AIBD analysis of Companies House data shows 489 new SIC 69.10 companies incorporated in Q2 2026, a 24.1% fall against the prior period. SIC 69.10 covers legal activities: solicitors, barristers, and the broader legal practice formation market.

A quarter-on-quarter drop of that magnitude in new legal entity formation is not noise. It may reflect founders delaying incorporation pending clarity on the ACSP filing requirements. It may reflect the cumulative weight of IDV obligations deterring casual incorporations. It may simply reflect a market in which the friction of getting a new legal practice off the ground has increased materially since the Economic Crime and Corporate Transparency Act began its phased implementation. Probably all three.

What it does not mean is that demand for legal and compliance services has declined. The opposite is closer to the truth. Firms already in practice are busier with regulatory work than at any point in the past decade. The formation rate tells you about the supply side. It says nothing reassuring about the workload arriving at the front desk.

The Debt Recovery Proposal in Historical Context

For those with a taste for regulatory history: HMRC's proposed direct bank account deductions have a precedent, of a sort. The 2015 Autumn Statement originally proposed direct recovery of debts from bank accounts, and it was withdrawn after a sustained campaign by professional bodies concerned about safeguards. ICAEW and others argued successfully that the protections were insufficient. The current consultation is differently structured, applying to instalment payments rather than lump sum seizures, but the principle is recognisably the same. Whether the professional bodies mount a similar response this time remains to be seen. The consultation is live. The submission window will not stay open indefinitely.

Next Deadline on the Horizon

6 July 2026 is the P11D submission deadline for the 2025-26 tax year. Benefits in kind provided to employees must be reported to HMRC by that date. Class 1A National Insurance contributions associated with those benefits must be cleared by 22 July for electronic payment or 19 July by cheque. These are not new deadlines. Firms that miss them in 2026 will find a regulator in a demonstrably less forgiving mood than in previous years.
