MicroFiler is an ICAEW regulated chartered accountants firm specialising in annual accounts, corporation tax, confirmation statements, and tax returns for micro companies. The firm has been filing for UK businesses for over 20 years and is registered with HMRC as an authorised tax agent. Alongside the core micro-company work, the firm also files for dormant limited companies, small limited companies, sole traders, and individual landlords. Every service runs on a fixed annual or monthly fee, with all prices published openly on the website.
A micro-entity company is a UK limited company that meets at least two of three conditions: turnover of £632,000 or less, balance sheet total of £316,000 or less, and 10 or fewer employees. Companies of this size form one of the largest segments of the UK business population and have specific filing requirements under FRS 105 of the Financial Reporting Standard.
MicroFiler has built its service around this segment for three reasons.
The filing requirements for micro companies are well-defined and consistent. FRS 105 simplifies disclosure compared to larger company reporting, which makes the work predictable in shape. Predictable work supports predictable pricing, faster turnaround, and consistent quality across hundreds of clients.
The recurring nature of the work builds depth quickly. The firm sees the same scenarios across micro-entity filings each year, including first-year accounts, dormant-to-active transitions, single-director companies with mixed salary and dividend structures, and contractor companies handling IR35 boundary cases. Familiarity with these scenarios shows up in the speed and accuracy of the work.
Clients in this segment are usually directors running their own business without an in-house finance function. The service is built to fit that reality. It removes admin from the director, files directly with HMRC and Companies House, and surfaces only the questions that a director actually needs to answer to approve a return.
Three principles guide how the firm operates.
Every service has a fixed price listed on the website. Dormant company accounts and corporation tax cost £285 a year. Micro company accounts and corporation tax cost £445 a year. Small company accounts and corporation tax cost £695 a year. MTD for Income Tax costs £199 setup plus from £25 a month. Self Assessment returns cost a fixed fee per return.
The fixed price covers the full filing service, including bookkeeping review, draft preparation, client review, and final submission. In practice, fixed pricing means clients know the cost before they engage, not after the work has been done.
MicroFiler is registered with HMRC as an authorised tax agent and submits filings directly to HMRC and Companies House on behalf of clients. Clients do not need their own Government Gateway accounts, presenter codes, or Companies House WebFiling credentials for routine filings. Where HMRC or Companies House query a submission, the firm responds to and resolves the query as the registered agent.
Day-to-day client work runs by email, which keeps a written record of every instruction, every approval, and every confirmation. The written record protects both client and firm: it shows what was filed, when, and on whose authority. Calls can be arranged for situations that call for them, but the default is written.
Four client groups make up most of the firm’s work.
Active limited companies with annual turnover up to £40,000 that meet HMRC’s micro-entity criteria. The firm files statutory accounts under FRS 105, the CT600 corporation tax return, and the annual confirmation statement.
Limited companies that need to remain on the Companies House register without active trading. The firm files dormant accounts (form AA02), the corporation tax return where required, and the annual confirmation statement.
Active limited companies with annual turnover up to £90,000. The firm files statutory accounts under FRS 102 Section 1A, the CT600 corporation tax return, and the annual confirmation statement.
Self-employed sole traders and individual UK landlords filing Self Assessment returns or, from April 2026 onward, MTD for Income Tax quarterly updates and final declarations. Common income types covered include trading profit, rental income from one or multiple properties, dividends, savings interest, and capital gains.
Four points define the firm’s positioning.
Years of repeating the same statutory filings produce a level of speed and accuracy that mixed-practice firms find harder to maintain across more varied work. The depth shows up in turnaround times, low error rates, and the quality of the questions the firm asks during preparation.
All prices are published on the website. There is no hidden quote process, no pricing bands behind a contact form, and no completion-stage upsell. Clients see the price before they engage.
Fixed fees of £285 a year for dormant companies, £445 a year for micro companies, and £695 a year for small companies sit below the rates many firms charge for the same statutory work. The price point reflects how the service is built and run rather than a discount on expertise.
The firm has been filing accounts and tax returns for UK companies for over 20 years. The continuity of experience matters when filing rules change, as they have repeatedly across that period: the introduction of FRS 105 in 2016, MTD for VAT in 2019, the Economic Crime and Corporate Transparency Act in 2023, and MTD for Income Tax in 2026.
MicroFiler operates under the registrations required of UK accounting firms.
The firm is registered with HMRC as an authorised tax agent for corporation tax, Self Assessment, and MTD for Income Tax filings. The agent registration permits the firm to submit returns directly to HMRC on behalf of clients and to handle HMRC correspondence as the registered agent.
The firm is registered with the Information Commissioner’s Office (ICO) for the processing of personal data under UK GDPR.
