Every question we get asked,
answered properly
Straight answers to the accounting, tax and VAT questions UK small business owners actually ask. Written by Claritax Accountants, a UK-wide fixed-fee remote accountancy firm.
Working with an accountant
Costs, switching, and whether you need one at all.
How much does an accountant cost for a small business in the UK?
Most UK small businesses pay between £30 and £200 per month depending on their structure and needs. At Claritax, fees are fixed and agreed in writing before we start: sole trader plans from £35 per month and complete limited company packages from £95 per month. See exactly what each plan includes on our pricing page.
Do I actually need an accountant for my small business?
Legally, no. Practically, most business owners save more in tax and penalties avoided than the accountant costs, and they get their evenings back. The case is strongest for limited companies, VAT-registered businesses and anyone employing staff, where filing mistakes carry real penalties.
What does an accountant do for a limited company each year?
The core cycle is: year-end statutory accounts filed at Companies House, a corporation tax return (CT600) filed with HMRC, the confirmation statement, director payroll, and the director's personal self assessment. A good accountant also plans your salary and dividend mix and flags tax savings before deadlines arrive. Full details on our limited company accounts page.
How do I switch accountants?
You sign one authority letter and your new accountant does everything else: professional clearance, collecting your records, and registering with HMRC as your agent. A typical switch completes inside two weeks and there is no bad time of year to do it. We explain the whole process on our switching accountants page.
Will my current accountant be difficult if I leave?
Almost never. Professional clearance is a routine courtesy process between firms and accountants handle it constantly. You never need to have the awkward conversation yourself; your new accountant contacts them for you.
What should I look for when choosing an accountant?
Four things: a recognised qualification or regulated firm, fixed fees agreed in writing, a clear response-time promise, and proactive advice rather than a once-a-year filing service. Ask any prospective accountant when they last contacted a client with a tax-saving idea the client had not asked about.
Is an online accountant as good as a local firm?
For most small businesses, yes, and often better: cloud bookkeeping means your accountant sees live numbers rather than a year-old shoebox, and remote firms typically respond faster because they are built around it. We serve clients everywhere from London to Birmingham without a single office visit.
Ask us directly. Every question gets a same-day answer, whether or not you are a client yet.
Limited companies & directors
Paying yourself, deadlines, and running a company properly.
What is the most tax-efficient way to pay myself from my limited company?
For most one-director companies it is a small salary (typically at or near the £12,570 personal allowance) topped up with dividends, reviewed each tax year as thresholds change. The right split depends on your income and circumstances. Our guide to paying yourself tax-efficiently covers the detail, and our salary and dividend calculator shows your numbers instantly.
What taxes does a limited company pay?
Corporation tax on profits at 19% up to £50,000 of profit, rising on a sliding scale to 25% at £250,000 and above, see our corporation tax calculator for your own figure. On top of that, the company handles VAT if registered and employer National Insurance if it runs a payroll. Directors then pay personal tax on what they draw out as salary and dividends.
When are my company accounts and tax return due?
Companies House accounts are due 9 months after your financial year-end, corporation tax payment 9 months and 1 day after year-end, and the CT600 return 12 months after year-end. A brand-new company's first accounts are due 21 months after incorporation, which arrives faster than most founders expect. Key dates are listed in our deadlines guide.
What is a confirmation statement?
An annual snapshot filing that confirms your company's registered details (directors, shareholders, registered office) with Companies House. It is due within 14 days of your review period ending each year. It is a small filing, but missing it can ultimately lead to your company being struck off.
What is a director's loan and is it taxed?
Any money you take from the company that is not salary, dividend or expense repayment sits on your director's loan account. If you owe the company more than £10,000 at any point, or the loan is unpaid 9 months after year-end, tax charges apply for you and the company. Tracked properly it is a useful tool; untracked it is one of the most common problems we untangle.
What expenses can I claim through my limited company?
Costs incurred wholly and exclusively for the business: software, equipment, travel (not ordinary commuting), a home-office allowance, professional fees, pension contributions and more. Claiming properly reduces corporation tax at up to 25%, so a thorough expense review usually pays for itself.
Should I close my company or make it dormant if I stop trading?
If you might trade again, dormancy keeps the company alive with minimal filings. If you are done for good, a formal closure (strike-off, or a members' voluntary liquidation for companies with significant retained cash) is usually better and can be very tax-efficient. The right route depends on how much is left in the company, so take advice before acting.
Self assessment
Who files, when, and what happens if you are late.
Who needs to file a self assessment tax return?
You generally must file if you are self-employed earning over £1,000, receive rental income, have significant untaxed income (dividends, crypto gains, side income), earn over £150,000, or HMRC has asked you to. First-timer? Our first self assessment page walks through the whole process.
When is the self assessment deadline?
Online returns and payment are due by 31 January following the end of the tax year; paper returns by the earlier date of 31 October. You must also register with HMRC by 5 October after your first tax year of untaxed income. All the dates are in our deadline dates guide.
What are payments on account?
Once your self assessment bill exceeds £1,000, HMRC asks you to prepay half of next year's estimated tax twice a year, on 31 January and 31 July. It surprises almost every first-time filer because the first January bill is effectively 150% of what they expected, our payments on account forecaster shows the split on your own numbers. A good accountant forecasts it months in advance.
What happens if I file my tax return late?
An instant £100 penalty the day after the deadline, even if you owe no tax. After 3 months, £10 daily penalties begin (up to £900), and at 6 and 12 months a further 5% of the tax or £300, whichever is higher, each time. Our late filing penalty calculator shows what you owe so far and what filing today saves. If you are already behind, our catch-up service stops the escalation.
What expenses can I claim as a self-employed person?
Costs that are wholly and exclusively for the business: materials, travel, phone and internet (business share), professional fees, marketing, and either simplified flat-rate home-working expenses or a share of actual household costs. Alternatively, the £1,000 trading allowance can replace expense claims for very small incomes.
How do I register for self assessment?
Register online with HMRC by 5 October following the end of the tax year in which your untaxed income started; HMRC then issues your Unique Taxpayer Reference (UTR). We handle registration for clients as standard, including chasing the UTR when HMRC is slow.
VAT
Thresholds, schemes and Making Tax Digital.
When do I have to register for VAT?
Registration is mandatory once your taxable turnover passes £90,000 in any rolling 12-month period, not your accounting year. You must also register if you expect to pass it within the next 30 days alone. Our plain-English VAT registration guide covers the details and edge cases.
Should I register for VAT voluntarily before the threshold?
Sometimes. If your customers are mainly VAT-registered businesses, voluntary registration lets you reclaim VAT on costs without making your prices effectively higher to customers. If you sell mainly to the public, it usually means either raising prices or absorbing the VAT. It is a genuine trade-off worth modelling before deciding.
Which VAT scheme is best for a small business?
The standard scheme suits businesses with significant VATable costs; the flat rate scheme can win for service businesses with few costs; cash accounting helps if customers pay slowly. The best choice depends on your cost profile and we review it as part of our VAT returns service.
What is Making Tax Digital (MTD)?
HMRC's requirement to keep digital records and file through compatible software rather than typing figures into the HMRC website. It already applies to VAT and is being extended to income tax for landlords and the self-employed. Cloud bookkeeping platforms like Xero, QuickBooks and FreeAgent handle it automatically.
Do I charge VAT to overseas customers?
Usually not for services supplied to businesses outside the UK, and the rules for goods depend on where they are shipped and who handles import VAT. Cross-border VAT is one of the most error-prone areas in tax, especially for e-commerce sellers, so get specific advice for your setup. See how we help online sellers.
Can I deregister from VAT if my turnover falls?
Yes, once you can show HMRC your taxable turnover will stay below the £88,000 deregistration threshold over the next 12 months. Whether you should depends on your customers and costs; deregistering means you stop reclaiming VAT on purchases too.

Payroll & employing people
What hiring really costs and what HMRC requires.
What does it cost to employ someone beyond their salary?
Budget roughly 12% to 18% on top of gross salary. The main additions are employer National Insurance at 15% on earnings above £5,000 per year and a minimum 3% employer pension contribution for eligible staff, plus holiday cover, equipment and software, our employee cost calculator works out the full figure for a given salary. The Employment Allowance can offset up to £10,500 of employer NI for qualifying businesses.
Do I need to run payroll if I am the only director?
If you pay yourself any salary, yes: the company needs a PAYE scheme and must report each payment to HMRC in real time, even for one person. Most directors run a simple annual or monthly scheme; it is quick when set up properly and included in our payroll service.
What is auto-enrolment?
The legal duty to enrol eligible employees (aged 22 to State Pension age, earning over £10,000) into a workplace pension, with minimum contributions of 8% of qualifying earnings, at least 3% from the employer. Duties start the day your first employee starts, and there are fines for missing them.
What is RTI?
Real Time Information: the requirement to report pay and deductions to HMRC on or before every payday, not at year-end. It is the reason payroll needs to run on time every single period, and it is handled automatically by proper payroll software.
Can I employ my spouse or family members in the business?
Yes, provided the pay is genuinely for work performed and at a commercially justifiable rate. Done properly it can use a family member's personal allowance and lower tax bands. Done as a paper exercise with no real work, it is a classic HMRC challenge, so keep evidence of the role.
Property & landlords
Rental income, capital gains and ownership structures.
Do I pay tax on rental income?
Yes. Rental profit (rent minus allowable expenses) is added to your other income and taxed at your marginal rate through self assessment. Allowable costs include letting agent fees, repairs, insurance and most running costs, but mortgage interest is treated separately. Our landlord accounting page covers the full picture.
What is Section 24 and how does it affect landlords?
Since 2020, individual landlords cannot deduct mortgage interest from rental profit; instead they receive a flat 20% basic-rate tax credit on the interest. For higher-rate taxpayers with mortgaged properties this raised effective tax bills significantly, and it is the main reason company ownership gets discussed so much.
How much is capital gains tax when I sell a rental property?
Residential property gains are taxed at 18% within your basic rate band and 24% above it, after the £3,000 annual exempt amount, our property capital gains tax calculator works this out on your own numbers. Crucially, the sale must be reported and the tax paid within 60 days of completion, a deadline many sellers only discover after missing it.
Should I hold my rental properties in a limited company?
Sometimes, but far less often than the internet suggests. Companies deduct mortgage interest in full and pay corporation tax rates, but moving existing personally-held properties in triggers stamp duty and possibly capital gains tax, and company mortgages cost more. It tends to suit higher-rate taxpayers building a portfolio with new purchases. Model the actual numbers before deciding.
I have never declared my rental income. What should I do?
Come forward voluntarily through HMRC's Let Property Campaign, which offers significantly better terms than waiting to be found (and HMRC does find landlords, via letting agents, deposit schemes and Land Registry data). We prepare the disclosure and negotiate the position for you, without judgement.
