HMRC’s consultation on tackling lower value tax debts closes at 11:59pm on 28 August 2026. This is not a soft policy note for the debt team. It is a cash-map change for every board that still treats sub-£10,000 tax balances as admin noise rather than a bank-account risk. The proposal would let HMRC recover lower-value debts by deducting affordable monthly instalments directly from UK bank and building society accounts where the customer has persistently not engaged.
Primary sources: the full consultation document, HMRC’s Direct Recovery of Debts (DRD) issue briefing, the tax debt strategy update, ICAEW’s note that the tool is effectively a “mandatory version of Time to Pay”, and the wider Tax Update 2026 package. If your working-capital model still assumes HMRC only bites hard above classic DRD thresholds, update it today.
The scale: why “small” debt is no longer small
HMRC’s numbers are blunt. Around 90% of customers pay in full and on time; the rest still creates roughly £100 billion of tax becoming debt each year. Within that stock, about 4.8 million individuals and companies hold debts at or below roughly £5,000 (individuals) / £10,000 (businesses) — around 11.5 million debts near £4 billion combined. Each year, more than 750,000 lower-value debts, worth over £2 billion, come back from debt collection agencies after failed recovery.
That is the gap. Court action and Taking Control of Goods are often uneconomic at these ticket sizes. Classic DRD — lump-sum recovery with a temporary hold and 30-day objection window — works as a deterrent but does not scale across high volumes of smaller balances. The new design is instalment automation, not another one-off grab.
Context for boards: HMRC’s debt strategy update puts the March 2025 tax debt balance at £42.8 billion (about 5% of receipts), with debt over a year old and not in a managed arrangement up from £5.3 billion in 2020 to £18.8 billion in 2025. Classic DRD restarted in a “test and learn” phase from September 2025 and broadened from April 2026. The lower-value tool is the next layer of that stack.
What changes versus classic DRD
Existing DRD, as set out in HMRC’s issue briefing, is still the reference baseline:
- Targeted at customers who can pay but will not engage after repeated contact.
- Debt threshold typically more than £1,000.
- A minimum of £5,000 left across accounts after deduction so wages, mortgages and essential costs are not wiped out.
- For individuals, a face-to-face visit before recovery is considered; companies and LLPs usually get multiple non-visit opportunities first.
- 30-day objection window after funds are held; county court appeal routes on specified grounds including hardship.
- Extra Support Team diversion where vulnerability indicators appear.
The consultation proposes extending that architecture into a high-volume regime:
- Instalments, not lump sums — monthly deductions sized off Time to Pay affordability logic.
- Expected envelope — HMRC does not expect in-scope debts to exceed about £10,000 (including interest and penalties at the point of action), with a possible lower individual cap still under design.
- All regimes, totalled — the customer’s combined tax debts across regimes, not a single siloed VAT or PAYE balance.
- Final chance first — only after standard collection is exhausted and a last opportunity to pay or contact HMRC.
- Automation with manual override — default machine process, but trained staff divert cases where support needs appear.
- Banks in the chain — UK banks and building societies would implement deduction instructions at scale.
ICAEW’s reading is useful: once instalments start, associated penalties are expected to stop accruing, as with conventional TTP. Early engagement remains the cheapest control. Disengagement no longer buys quiet permanence on a £3,000–£8,000 stack of CT, VAT, PAYE and interest.
CFO cash and control implications
Treat this as a treasury and controls problem, not a pure tax technicality.
1. Bank account topology becomes tax-sensitive. If HMRC can instruct monthly draws from the operating account that funds payroll, supplier runs and covenant tests, your liquidity ladder needs a named owner for HMRC correspondence. Shared inboxes are how persistent non-engagement is manufactured. Map which entities hold which UK accounts, who receives statutory post and digital alerts, and how quickly a Time to Pay request can be authorised.
2. Small multi-regime balances compound. The consultation is explicit that the power looks at total tax debts across regimes. A £2,400 VAT remainder, a £1,800 PAYE underpayment and £900 of interest are not three harmless leftovers — they are one enforcement candidate. Your tax risk dashboard should show consolidated HMRC exposure by entity, not only the next big return deadline.
3. Time to Pay remains the preferred off-ramp — if you engage. HMRC cites roughly 90% successful completion of TTP plans with an average length around 14 months. Online self-serve options continue to expand for lower balances. The new power is designed for the population that ignores that route. From a board perspective, a managed TTP is almost always better than an automated draw you did not schedule against the cash forecast.
4. Group and PE portfolio hygiene. Thin finance teams, post-deal systems migrations, or disputed assessments parked “pending adviser review” are exactly where letters age into “persistent non-engagement.” Put a monthly HMRC debt ageing report into the PE pack: balance, regime, age, last contact, TTP status, and Extra Support or dispute markers. For holdcos and SPVs, name a responsible officer for HMRC mail and Agent Services monitoring.
5. Working-capital covenants and audit committee narrative. Automated instalments are still cash outflows. Near RCF headroom or tight supplier terms, an unplanned HMRC draw can create a secondary problem even when the tax itself is “small.” Put known HMRC debt service into the 13-week cash forecast, and disclose material enforcement risk in the audit committee tax paper the same way you would flag a threatened winding-up petition.
6. Vulnerability and hardship processes are not optional theatre. The consultation stresses Extra Support diversion, hardship-aware instalment design, objection rights, complaints routes and potential tribunal oversight where the power is misapplied. Evidence capacity or trading-shock markers early if a genuine hardship case sits inside the group — do not wait for the deduction notice.
Where this sits in the wider 2026 stack
Do not read it in isolation. Tax Update 2026 and ICAEW coverage place it beside:
- mandatory Direct Debit proposals for much of VAT and PAYE payment;
- more timely payment design for Income Tax Self Assessment;
- MTD for Income Tax live from April 2026 for the first cohort;
- restarted classic DRD after the COVID pause;
- heavier use of debt collection agencies on older stock.
Direction of travel: fewer forgotten balances, more automated payment rails, less patience for silence. CFOs who still run tax cash as an annual Self Assessment or quarterly VAT event will under-model the monthly friction.
What every CFO should lock this week
- Debt inventory by entity and regime — CT, VAT, PAYE/NIC, Construction Industry Scheme, personal liabilities of directors where relevant, interest and penalties. Age everything. Flag anything over 60 days without a live TTP or formal dispute.
- Engagement log — last HMRC letter, portal message, agent contact, and response. “We never saw it” is the fact pattern this power is built to defeat.
- TTP decision rights — who can approve a plan within 48 hours, including out-of-hours cover for month-end and holiday periods.
- Bank mandate map — UK accounts that could receive a deduction instruction; minimum cash buffers; which account funds payroll.
- Agent and software alignment — Agent Services account access, Making Tax Digital software, and the person who owns bounce-back mail from HMRC and the bank.
- Board language — one paragraph in the next finance pack: scale of lower-value HMRC debt, engagement status, and residual risk if the power is enacted broadly after consultation responses.
- Response window — views on design (value caps, company vs individual thresholds, bank burden, hardship tests) still go to taxdebtsconsultation@hmrc.gov.uk until tonight. After that, plan for the legislation that follows the response summary later this year.
Bottom line
Classic DRD taught the market that HMRC can reach into a bank account when someone can pay and will not talk. The 28 August consultation does the same job at industrial scale for the long tail of lower-value debt — monthly instalments, across regimes, automation first, human override where vulnerability appears. ICAEW’s “mandatory TTP” framing is the right management metaphor.
For CFOs, the control is not clever structuring. It is boring excellence: see the debt early, answer the letter, put affordable cash against a plan you own, and keep the operating account out of silent default. Most losers under this regime will simply be the ones who never opened the envelope — a process failure, not a technical tax mystery, and fixable before the power hardens into statute.
