Every quarter, BTG (formerly Begbies Traynor) publishes its Red Flag Alert. Every quarter, founders scroll past it because it's about pubs and hotels. This quarter, read it properly.

The Q2 2026 edition puts 53,756 UK companies in "critical financial distress" — up 9% on last year, with 21 of the 22 sectors tracked getting worse. Winding-up petitions rose 15.7% across 2025. And buried a few paragraphs down is the number that should actually stop you: HMRC was owed around £27 billion in corporation tax, PAYE and VAT at the end of 2025.

‍

That £27bn isn't a statistic about the economy. It's a statistic about how thousands of businesses funded their last twelve months.

‍

The lender you never applied to

‍

Here's the uncomfortable mechanic. VAT you've charged customers isn't your money. PAYE you've deducted from salaries isn't your money. But both sit in your bank account for weeks before they're due, and when cash is tight, they are the easiest thing in the world to lean on.

‍

Nobody decides to borrow from HMRC. They just pay the payroll first, then the supplier who's chasing, then look at the VAT return and think next month. Three "next months" later, the balance sheet has a creditor on it who doesn't negotiate like a supplier, doesn't need a court order to start enforcement, and charges late payment interest at Bank Rate plus four points — currently 7.75% with Bank Rate at 3.75%.

‍

It is, by some distance, the most expensive line of credit most UK startups will ever use. And it doesn't appear on any funding slide.

‍

Why the P&L won't warn you

‍

The reason this catches founders out is structural. VAT and PAYE liabilities live on the balance sheet, not the P&L. Your monthly profit figure can look perfectly healthy while the HMRC creditor quietly grows underneath it. If your management accounts are a P&L and a bank balance — and for a lot of early-stage companies, that's exactly what they are — you are flying without the one instrument that matters.

‍

The context makes it worse. The Bank of England's August Decision Maker Panel found 61% of UK firms expect lower profit margins over the next year because of the energy shock, and 59% expect to raise prices. Margins are compressing across the board. That's precisely the environment in which "next month" becomes a habit.

‍

What a startup finance health check actually asks

‍

When we run a finance health check for a founder, we don't start with the P&L. We start with one number: real cash. Bank balance, minus VAT collected but not yet paid, minus PAYE and NI accrued, minus the next payroll. That's the cash you actually own. For a surprising number of businesses with a "comfortable" six-figure balance, real cash is close to zero or negative.

‍

Then we ask whether the management accounts for the startup show that number every month, alongside the P&L. Not in the year-end accounts. Not when the accountant files the VAT return. Every month, on the same page as revenue.

‍

Then the harder questions. Is the business profitable after the tax it's holding, or only before? Are debtor days creeping up while the HMRC balance creeps up alongside them? Has anyone actually modelled the next VAT quarter and the next corporation tax payment against the forecast, or is the plan simply that revenue will have caught up by then?

‍

None of this is complicated. It's just rarely done, because tax feels like an accountant's job and cash feels like a founder's job, and the gap between the two is where the £27bn lives.

‍

Time to Pay is a symptom, not a strategy

‍

HMRC's Time to Pay arrangements exist and they work. But if you find yourself on the phone negotiating one, understand what has already happened: your business borrowed money it didn't plan to borrow, from a creditor it didn't choose, to cover a gap it didn't see coming. The arrangement fixes the symptom. The forecasting gap that created it is still there.

‍

Critical distress isn't a lightning strike. Ric Traynor, BTG's chairman, described the rise in winding-up petitions as an ominous sign with no relief in sight. Most of the 53,756 companies on that list made the same small decision — we'll sort HMRC next month — twelve or eighteen months before the petition arrived.

‍

The businesses that stay off the list aren't the ones with more cash. They're the ones who knew, every month, exactly how much of the cash was theirs.

‍

Not sure how much of the money in your account is actually yours? Take a free hour with us and we'll run a startup finance health check — real cash, HMRC position, and what the next two quarters look like — no pitch, no boring numbers. Finance leadership, without the headcount.
