Running your own insurance brokerage means freedom from office politics and control over your own diary. It also means understanding your tax bill, which isn't as straightforward as PAYE. Many brokers we speak to are surprised by how much tax they owe once they've factored in National Insurance contributions. It's worth getting your head around this properly rather than discovering a nasty surprise in January.
The amount you'll pay depends on three things: how much you earn, whether you're a sole trader or limited company, and what deductions you can legitimately claim. There's genuine variation here, and the structure you choose genuinely matters.
Income Tax: The Straightforward Part
Income tax itself is the simplest piece of the puzzle. For the 2024-25 tax year, you pay nothing on your first £12,570 of profit (the personal allowance). After that, you pay 20% up to £50,270. Above that threshold, you move into the 40% higher rate.
If you're running a successful brokerage and earning £60,000 in profit, that's £12,570 tax-free, then £37,700 at 20%, which comes to £7,540. Sounds manageable. But then National Insurance enters the room.
National Insurance: The Hidden Tax Nobody Mentions
This is where self-employed brokers get caught out. As an employed person, your employer pays part of your National Insurance. Self-employed? You pay both parts yourself.
You pay 8% on profits between £12,570 and £50,270. Above £50,270, it drops to 2%. There's also a flat charge of £163.80 per year (2024-25) to maintain your National Insurance record, though you're exempt if earnings fall below £6,725.
Back to that £60,000 profit example. National Insurance would be: £37,700 at 8% equals £3,016, plus the annual charge of £163.80. That's £3,180 in National Insurance alone. Combined with income tax, you're now paying £10,720 on £60,000 profit, which is nearly 18%. Suddenly less cheerful.
This is why many brokers earning above £50,270 seriously consider incorporating as a limited company. The maths change when you can split income between salary and dividends.
Should You Incorporate? The Limited Company Question
There's no universal answer, but here's how it works. As a limited company, you might pay yourself a salary of £12,570 (matching the personal allowance). No income tax, no National Insurance. Then take the rest as dividends.
Dividends face Corporation Tax first. The rate is 19% on profits up to £50,000 (small profits rate). Once you've paid that tax, the remaining dividend is yours. You then pay dividend tax on it at 20% (higher than the basic rate now, after recent changes) if you're a higher rate taxpayer, but you get a £1,000 annual dividend allowance tax-free.
Let's say your brokerage makes £60,000 profit. Pay yourself £12,570 salary. That leaves £47,430. Corporation Tax at 19% is £9,011. You're left with £38,419 as distributable profit. If you take that as dividends, you pay 20% on the amount above £1,000 of allowance. That's £7,484 dividend tax. Your net take-home is roughly £43,905 plus the £12,570 salary. Total: £56,475.
Compare that to sole trader status on the same £60,000 profit: £60,000 minus £10,720 tax and National Insurance leaves £49,280 in your pocket.
The limited company doesn't win here, but it changes the picture if you're reinvesting profits or retaining earnings for business growth. You could leave profit in the company, pay Corporation Tax at 19%, and avoid the additional layers of National Insurance and higher-rate income tax. For brokers planning to build significant retained earnings, this is genuinely valuable.
Pension Contributions: One Tool That Works Both Ways
If you're self-employed, pension contributions are deductible from your profits before you calculate tax. If you earn £60,000 and pay £5,000 into a pension, you pay tax on £55,000 instead.
This reduces both income tax and National Insurance. On that £5,000, you're saving roughly £1,200 in combined tax and NI (at 20% income tax plus 8% NI). For a higher earner in the 40% bracket, it's nearer £2,400 on a £5,000 contribution. If you've had a particularly strong year in commissions, this is an efficient way to save for retirement whilst managing your immediate tax bill.
What You Can Actually Claim
Many brokers overlook deductions. You can claim professional fees (FCA registration, continuing professional development), office costs (rent if you have dedicated space, utilities, broadband), vehicle expenses if you visit clients, insurance (professional indemnity, business liability), accountancy fees, and software subscriptions. Even if you work from home, you can claim a proportion of your costs.
The test is simple: would you incur this expense if you weren't running the brokerage? If yes, it's usually deductible. Marketing, advertising, training in new insurance products, travel to industry conferences. These all count. Proper record-keeping is essential. HMRC is increasingly automated, and they do look at self-employment returns for the financial services sector.
Getting Help You Can Actually Use
This is complex enough that speaking to an accountant who understands insurance brokerage is worth every penny. They'll spot structure opportunities you've missed and ensure you're claiming everything you're entitled to. A good accountant costs £500 to £1,500 annually but often saves more in legitimate tax reductions than their fee.
There's no shame in getting professional help here. Most successful brokers do.
