If you run a small or owner-managed business, you’ve probably felt this over the last few years:
“We’re doing our best, but it feels like HMRC are on our case more than ever.”
You’re not imagining it.
HMRC has made it very clear that small businesses are now a prime focus for closing the “tax gap”, the difference between what they think should be collected and what actually comes in.
The uncomfortable reality is this:
- Small businesses now account for the majority of that tax gap.
- HMRC is investing heavily in compliance and debt collection specifically aimed at this group.
Let’s unpack what that means in real life, and what you can do so your business isn’t the one they decide to make an example of.
Why HMRC is suddenly so interested in small businesses
For years, the story has been about “cracking down on big multinationals”.
That plays well in headlines. But if you’re HMRC and you want to actually collect more money, you go where:
- There are lots of taxpayers
- Processes and records are often a bit messy
- People are more likely to make mistakes
That’s the small business sector in a nutshell.
So HMRC has:
- Put more money into compliance teams
- Upgraded their data-matching and risk systems
- Started targeting sectors and behaviours they think are “high risk”
This isn’t about “evil HMRC”. It’s about a system under pressure, looking for easy wins.
And a busy small business with patchy records is a very easy win.
What this crackdown looks like in practice
You might picture a dramatic dawn raid and brown envelopes everywhere.
In reality, HMRC’s new push looks more like this:
- More nudge letters:
“We’ve noticed XYZ on your return, please check and correct if necessary.” - More enquiries triggered by software:
Their systems flag things like unusual margins, mismatched data, late returns, inconsistent payroll. - More focus on “known risky” areas, such as:
- VAT (especially in cash-heavy businesses)
- CIS in construction
- Director’s loan accounts
- Undeclared benefits in kind
- R&D claims that look too good to be true
- Non-compliant or unregulated “tax scheme” advisers
- More pressure on old tax debts:
If you’ve got historic arrears or Time to Pay arrangements, expect less patience and more chasing.
It’s less “detective drama” and more “constant background pressure”.
The brutal truth: most problems are not deliberate
In my experience, most of the small businesses HMRC are contacting are not crooks.
They are:
- Growing quickly with no time to sort systems
- Relying on outdated processes that haven’t kept up with the size of the business
- Doing their own bookkeeping on weekends
- Following “advice” picked up from a mate, a forum, or a cheap, box-ticking accountant
Typical issues I see all the time:
- VAT:
- Claiming VAT on things you shouldn’t
- Not applying the correct VAT rate
- Messy partial exemption or mixed supplies
- Late and inconsistent submissions
- Payroll & PAYE:
- Incorrect treatment of benefits and expenses
- Directors’ salaries not matching RTI submissions
- Missing or incorrect auto-enrolment complianc
- CIS (Construction):
- Wrongly treating people as self-employed
- Incorrect deductions and returns
- Poor records of what’s been withheld or paid over
- Director’s loan accounts:
- Directors “borrowing” from the company with no plan to repay
- Overdrawn accounts triggering Section 455 charges
- Dividends declared after the event to try and fix it
None of these usually start as fraud.
They start as “We’ll sort that later.”
HMRC’s new approach is built around the idea that “later” never comes, and that’s where they’ll find easy money.
Why this is dangerous in the current climate
HMRC stepping up compliance wouldn’t be so bad if everything else were calm.
But at the same time, you’re dealing with:
- Higher wages and running costs
- A rising overall tax burden
- Higher interest rates and tighter lending
Which means:
- A surprise VAT bill, PAYE underpayment or s455 charge can be genuinely damaging.
- You have less spare cash to throw at unexpected demands.
- The stress lands on your shoulders, usually at the worst possible moment.
This is why I keep banging on about getting ahead of compliance, not because I like rules, but because I don’t want you wasting your hard-earned profit on avoidable mistakes.
What “good” looks like to HMRC (and should look like to you)
If HMRC turned up tomorrow, in person or digitally, here’s what would make your life a lot easier.
1. Clean, consistent bookkeeping
Not perfect. Not beautiful. Just:
- Up to date
- Bank reconciled
- Sales and purchases posted to the right codes
- VAT treated consistently
If your records are three quarters behind, on a spreadsheet nobody else understands, you’re starting on the back foot.
2. VAT done properly, not just submitted on time
MTD means lots of businesses are now submitting VAT digitally, but:
- Digital rubbish is still rubbish.
You want:
- Clear evidence behind your VAT returns
- A sensible approach to things like fuel, entertaining, assets
- Confidence that the numbers could be explained if someone asked
3. Payroll that matches reality
HMRC’s systems see your payroll data in real time.
So you want:
- Directors and staff actually being paid what RTI says they are
- Benefits and expenses treated correctly
- Bonuses, commissions and overtime properly recorded
If what you’re doing in the bank doesn’t line up with what’s being reported, alarms go off.
4. Director’s loan accounts under control
As a rule of thumb:
- Don’t use the company as your personal overdraft.
- Don’t let your director’s loan account drift further and further overdrawn.
You want a clear plan:
- Are you going to repay it?
- Or clear it via properly documented dividends/bonuses that make sense for the business?
A messy DL account is one of the first places HMRC will look.
5. Avoiding “too good to be true” schemes
If you’ve ever been sold:
- A very aggressive R&D claim
- A “magic” way of paying almost no tax as a director
- Highly creative uses of offshore structures, image rights or contrived arrangements
You might be sitting on a ticking time bomb.
HMRC is paying particular attention to non-compliant advisers and the clients they’ve put into schemes.
If something feels too clever for your size of business, or you don’t fully understand it, it’s worth getting a second opinion.
The mindset shift: from “hope we’re fine” to “we know we’re fine”
Most small businesses live in one of these three states:
- Blissful ignorance
- “HMRC leave us alone, so we must be fine.”
- (Translation: “We’ve just not been picked yet.”)
- Quiet anxiety
- “I really hope everything we’re doing is okay”
- (You’re pretty sure there are gaps, but you’re too busy to look.)
- Calm confidence
- “We know where the risks are and we’ve tidied them up.”
- (Not perfect, but robust enough to sleep at night.)
In a world where HMRC is actively targeting small businesses, Option 1 is getting riskier by the year.
The goal isn’t perfection. It’s to move you from 1 or 2 into 3.
What I’d do now if I were you
If you’re an owner-manager and any of this is ringing alarm bells, here’s a simple plan:
- Be honest with yourself
- How up to date are your records?
- Are VAT, PAYE, CIS and corporation tax all filed and paid on time?
- Do you actually understand your own director’s loan position?
- Identify the “red zones”
- Construction? I’d look at CIS and VAT first.
- Hospitality/retail? I’d look at cash handling, tips, VAT.
- Consultancy/online? I’d look at VAT, overseas customers, R&D if relevant.
- Get a professional to stress-test your setup
- Ask an accountant who actually cares (not just files) to review your systems as if HMRC had asked to see them.
- Fix the quick wins first
- Tidy up book-keeping
- Sort DLAs
- Correct obvious VAT or PAYE issues
- Get rid of anything that looks like a dodgy scheme
You don’t have to do everything at once. But doing nothing is now the riskiest option on the table.
