ABOUT

Affordable UK tax filing, built for micro-entity directors.

Directors with prepared figures can use suitable software to file their Company Tax Return and accounts. Our generated company accounts use FRS 105 for eligible micro-entities. For periods beginning on or after 6 April 2025, the size test uses at least two of three limits: annual turnover no more than £1,000,000, balance sheet total no more than £500,000 and an average of no more than 10 employees. Adjust turnover for the accounts-period length and apply the qualifying-year rules and exclusions.

We appear as SimpleCompanyTax on HMRC’s Corporation Tax software supplier list. This listing is not an HMRC endorsement. Explore supported features.

Why we exist.

We built a purpose-built filing platform that handles the full CT600 and iXBRL workflow for micro-entities at a fraction of the traditional cost by focusing scope and automating routine preparation and filing.

PRODUCT

What we do.

SimpleCompanyTax prepares and files:

  • CT600 corporation tax returns: HMRC-compliant XML, submitted via Government Gateway with IRmark receipt.
  • iXBRL statutory accounts: tagged against the FRS 105 (micro-entity) taxonomy, accepted by Companies House and HMRC.
  • Tax computations: Corporation Tax with marginal relief where applicable.

Everything is generated from a single guided session, with no manual XML editing, no iXBRL tagging tools.

APPROACH

Compliance first. Focused scope. Transparent pricing.

Compliance first

Every return we generate is validated against HMRC's Corporation Tax schema v3 and the FRC's iXBRL taxonomy. We compute to the penny and validate to the specification.

Focused scope

We deliberately serve one market: UK micro-entity limited companies with straightforward filing needs. By not trying to be everything to everyone, we can automate more deeply and charge less.

Transparent pricing

Two simple prices per company, per year: £10 +VAT for dormant companies and £25 +VAT for eligible active micro-entities using FRS 105. Supported filings and amendments are included for each paid year. Check your accounts standard and filing route before buying.

AUDIENCE

Who we're built for.

Micro-entity directors who want filing done properly without the accountant fees.

Who we're for

  • Dormant-company directors who need to file annual returns without paying accountancy fees
  • Single-director micro-entities with straightforward income and expenses
  • Low-turnover trading companies that don't need full-service accountancy software
  • Accountants managing multiple micro-entity clients who want faster, cheaper preparation

Who we're not for

  • R&D tax credit claimants
  • Group relief or consolidated accounts
  • Companies that prepare group accounts or are consolidated into a parent
  • Companies with overseas permanent establishments

If your company falls into one of the excluded categories, you'll need specialist software or professional advice, and we'll tell you so.
