Do I need an accountant?
No UK business is legally required to use an accountant - you can file everything yourself for free. The real question is whether one pays for itself in tax saved, time returned and risk removed. That depends entirely on your situation, so here it is by type.
If you are employed (PAYE only)
Usually no. If all your income is a salary taxed under PAYE, your tax is handled automatically and you generally do not need to file anything, let alone pay an accountant. The exception is if you have side income, high earnings, or something unusual like a large one-off gain.
If you are a sole trader or freelancer
It depends on how simple things are. A single income stream with tidy records is a return you can file yourself for free. Once you have expenses to judge, a first year of trading, or income alongside a job, an accountant earns the GBP 150-400 fee by finding allowances and taking on the accuracy risk. See our Self Assessment cost guide.
If you are a landlord
Often worth it. Property income has its own rules - what counts as an allowable expense, the mortgage-interest restriction, and how gains are taxed on sale. One property may be manageable alone; a portfolio, or anything involving a sale, is where an accountant usually pays off.
If you run a limited company
Almost always yes. You can file company accounts and Corporation Tax yourself, but they follow statutory formats, the penalties for errors are steeper, and directors have duties. The fee is modest against the risk, and a company is where salary-and-dividend planning tends to save real money. See the limited company cost guide.
The honest test
Ask two things: is there judgement involved in my tax, and is my time worth more than the fee? If your affairs are genuinely simple, filing yourself on GOV.UK is fine and free. The moment there are decisions to make - a company, VAT, property, capital gains, or a business growing fast - an accountant usually returns more than it costs. And whatever you decide, if you do hire one, check they are qualified and regulated first.

Frequently asked questions
Do I legally have to have an accountant?
No. There is no legal requirement to use an accountant for any UK business, including a limited company. You can prepare and file everything yourself. Most people use one because it saves time, reduces errors, and often recovers its own cost in tax saved.
Can I do my own limited company accounts?
Yes, it is allowed. But company accounts follow statutory formats, the Corporation Tax return has its own rules, and the penalties for mistakes are higher than for a sole trader. Most directors decide the modest fee is worth the certainty.
When is an accountant not worth it?
If you are employed under PAYE with no other income, you usually do not need to file anything at all. And a very simple sole trader return with one income source is straightforward to file yourself for free on GOV.UK. The value appears once there is judgement involved.
Will an accountant save me more than they cost?
Often, but not always. For simple affairs the fee may exceed the tax saved. As soon as there are allowances, reliefs or structuring decisions in play - rental property, a company, VAT, capital gains - a good accountant frequently saves more than the fee, on top of the time and risk removed.
