Small Business Accountants London- Fixed Fee, No Surprises

Yes. A UK Limited Company must file statutory accounts with Companies House and a Corporation Tax return (CT600) with HMRC every year. While not legally required, a qualified accountant ensures compliance, claims all available reliefs, structures director pay efficiently, and protects you from costly HMRC penalties.

Small business accountant fees in London typically range from £75 to £300 per month on a fixed fee basis, depending on business structure, VAT registration, payroll complexity, and transaction volume. Protax Consultants offers transparent fixed-fee packages from £75 per month with no hidden charges.

A fixed fee accountant charges a pre-agreed monthly or annual fee covering a defined set of services, rather than billing by the hour. This gives small business owners cost certainty and removes the fear of unexpected invoices. All Protax packages are fixed fee, agreed in writing before we begin.

Yes. We support startups from before incorporation, advising on sole trader vs limited company, registering with Companies House, setting up Xero, VAT registration where needed, and building a tax-efficient structure from day one. Early-stage tax planning saves far more than reactive compliance.

Yes. Protax Consultants is based at Lombard Business Park, Wimbledon, SW19 3TZ. We offer in-person meetings at our Wimbledon office and a fully digital service for clients across London and the UK who prefer remote support.

Making Tax Digital is HMRC’s programme requiring businesses to keep digital records and submit tax data through compatible software. MTD for VAT is already mandatory for all VAT-registered businesses. MTD for Income Tax Self Assessment (MTD for ITSA) applies from April 2026 for those earning over £50,000. We ensure full compliance for all clients.

If HMRC opens a compliance check, aspect inquiry, or full investigation, Protax manages all communication on your behalf. We respond professionally, gather the required evidence, and represent your business throughout the process. You are never left to deal with HMRC alone.

Yes. Protax is Xero Certified and supports QuickBooks and Sage users. We set up, configure, and review your cloud accounting software to ensure it integrates correctly with your tax position and MTD obligations.

Switching accountants typically takes one to two weeks. We manage the entire transition, contacting your previous accountant, obtaining all records and authority letters, and setting up your new file. There is no disruption to your business and no HMRC penalty for changing advisers mid-year.

Mandatory VAT registration is required when your taxable turnover exceeds £90,000 in any rolling 12-month period (2025/26 threshold). You can voluntarily register below this threshold, which may be beneficial for recovering input VAT. We monitor your turnover and advise on the optimal timing and scheme.

A sole trader is a self-employed individual personally liable for all business debts, taxed through Self Assessment. A limited company is a separate legal entity offering liability protection and often a more tax-efficient structure for profits above approximately £35,000. We advise on the right structure for your situation and income level.

Yes. Many of our clients require both company accounts and a director's Self Assessment tax return. These are filed together within our standard limited company package. We handle both HMRC submissions and Companies House filings, and ensure your personal and company tax positions are optimised together.

We recommend Xero for most small businesses due to its ease of use, bank feed integration, MTD compliance, and strong reporting features. For clients already on QuickBooks or Sage, we provide full support on those platforms. We set up, configure, and train you on your chosen software as part of our onboarding process.

No. While our office is in Wimbledon, SW19, we serve clients across all London boroughs and throughout the UK. Our fully digital service means geography is no barrier. Many clients across South West London, Central London, and the rest of the UK never visit our office and receive an identical quality of service remotely.

From April 2023, UK Corporation Tax operates on a two-rate structure. Companies with profits up to £50,000 pay 19%. Companies with profits above £250,000 pay 25%. Companies in between pay a tapered rate via marginal relief. We calculate your exact liability and identify every legitimate relief available to minimise your bill.
