Ever feel like running a limited company is like trying to follow a rulebook that no one handed you? You’re not alone. Whether you’ve just started your limited company or you’re thinking about making the leap, chances are you’ve heard a lot of conflicting advice—some of it flat-out wrong.
In this blog, we’re busting ten of the most common myths about limited companies in the UK. Why? Because falling for these could cost you time, money, and maybe even land you in trouble with HMRC.
Let’s set the record straight.
1. “I can use the company bank account however I want.”
Wrong. Your limited company is a separate legal entity—basically, it’s its own (imaginary) person. That means you can’t treat the business bank account like your personal piggy bank. If you start taking money out without proper justification—like salary, dividends, or business expenses—you could trigger a tax headache. And no one wants that.
Takeaway: Keep your company and personal finances separate. Always.
2. “I don’t need an accountant—I’ve got QuickBooks.”
Ah yes, the classic “DIY accounting” myth. While cloud software is brilliant for day-to-day bookkeeping, it won’t file your company accounts, produce your corporation tax return, or keep you fully compliant with HMRC. Plus, one wrong entry could lead to a full-blown tax investigation.
Takeaway: Think of your accountant as your compliance safety net—not a luxury, but a necessity.
3. “I haven’t made any money, so I don’t need to file anything.”
Nope. Even if you’ve made zero profit—or didn’t trade at all—you still need to file your accounts with Companies House each year. And unless your company is dormant, you’ll also need to submit a corporation tax return.
Takeaway: No activity, no responsibility. Stay on top of your filings or face penalties.
4. “I’ve got limited liability, so I’m fully protected.”
Well… sort of. While limited liability can protect your personal assets, most banks won’t lend to a brand-new company without a personal guarantee. That means if your company defaults on a loan, you’re still on the hook.
Takeaway: Read the fine print before signing anything—and don’t rely solely on limited liabil
5. “I’ll just take dividends and avoid tax.”
Sounds lovely, doesn’t it? But dividends come after corporation tax (which ranges from 19%–25%) and are not tax-deductible. On top of that, you’ll pay dividend tax based on your personal tax band.
Takeaway: Work out your total effective tax rate before deciding how to pay yourself—it might surprise you.
6. “VAT? I’ll worry about that later.”
If your turnover exceeds £90,000 per year, VAT registration becomes mandatory—unless your business is VAT-exempt. And once registered, you’ll need to file quarterly VAT returns. Yes, it’s admin. But it also means you can reclaim VAT on your purchases.
Takeaway: Don’t sleepwalk into VAT obligations. Know your numbers and plan ahead.
7. “I can just use my personal bank account.”
Stop right there. Mixing personal and business transactions is a recipe for confusion—and potentially missed tax reliefs. Plus, it just looks unprofessional.
Takeaway: Open a separate business bank account. It’ll save you time, stress, and accounting fees later on.
8. “I don’t need a payroll—I’m the only one in the business.”
Technically, that’s true. But if you’re taking money out, a small salary can be a smart move. Why? Because it’s tax-deductible for the company and could reduce your overall tax burden.
Takeaway: Pay yourself strategically. A bit of payroll planning can go a long way.
9. “HMRC will tell me everything I need to do.”
We hate to break it to you—but they won’t. Yes, they’ll send reminders for deadlines, but they won’t spoon-feed you all your legal responsibilities. As a director, that’s on you.
Takeaway: Be proactive. Know your responsibilities—or get help from someone who does.
10. “If things go wrong, I’ll just walk away.”
Wishful thinking. If your company becomes insolvent (more liabilities than assets), you can’t just disappear. You’ll need to go through a formal liquidation process, and it will leave a mark on your record.
Takeaway: Always have an exit strategy. And ideally, build your business with a view to sell, not run from
