Why Misunderstanding Tax Can Destroy a Profitable Business

30/03/2025by admin

Many business owners think they understand tax—but in reality, this misconception is silently killing businesses across the UK. 

At Adaptive Accountancy, we’ve worked with hundreds of small business owners and directors who come to us after realising too late that their tax understanding didn’t match the financial decisions they were making. 

Today, we want to share a real (and very common) client scenario that highlights just how dangerous this misunderstanding can be—and why proper tax planning with a good accountant is essential. 

 

The Client Thought They Were Fine – Until We Broke Down the Numbers 

Last week, a potential client sat down with us for a discovery call. 

After the usual introductions and small talk, we started talking about their lifestyle and income needs. 

“I only need about £60,000 a year,” they said. “The business makes that easily, so I’m good.” 

That sentence made my ears prick up. 

Because they weren’t good—not even close. 

 

Let’s Break Down the Tax Reality 

Here’s what the client thought was happening: 

  • £12,570 paid through payroll (tax-free personal allowance) 
  • £47,340 paid via dividends 
  • Total income = £60,000 

But what they hadn’t accounted for was personal tax on the dividends. 

The Reality: 

  • Personal tax due = £6,508 
  • Actual take-home = £53,492 

Suddenly, they’re £6,508 short of their target lifestyle. 

To hit their £60,000 take-home goal, we ran the numbers again: 

  • PAYE salary: £12,570 
  • Dividends: £57,300 
  • Personal tax: £9,870 
  • Net income: £60,000 

 

The Business Needs to Earn More Than You Think 

To extract that much in dividends, the company needs available post-tax profits of £57,300. 

Which means: 

  • Profit before tax: £72,860 
  • Corporation tax (at 25%): £15,560 
  • Available for dividends: £57,300 

Add in the PAYE salary, and the business actually needs to profit £85,430, not £60,000. 

That’s £25,430 more than the client realised. 

 

What Happens Without Tax Planning? 

This is where it gets dangerous. Without an accountant who proactively explains tax, here’s what can go wrong: 

You withdraw £60,000 thinking you’re covered
You forget the personal tax due
You keep withdrawing more than the business can actually afford
You create an overdrawn director’s loan account (a serious red flag with HMRC)
You face interest charges, additional tax liabilities, and stress you weren’t prepared for 

Worst of all, you’ve already spent the money—so when the tax bill hits, you can’t afford it. 

 

We See This Too Often – And It’s Avoidable 

We’ve seen many clients in this position—hard-working business owners who simply didn’t realise how tax actually works. They weren’t reckless—they just weren’t informed. 

And the shame that follows is real:
💬 “I’ve let my family down.”
💬 “I’ve got to get a job again.”
💬 “I thought we were doing well.” 

But it doesn’t have to be this way.
