Compliance first
Every return we generate is validated against HMRC's Corporation Tax schema v3 and the FRC's iXBRL taxonomy. We don't approximate — we compute to the penny and validate to the specification.
ABOUT
Affordable UK tax filing, built for micro-entity directors.
Over one million UK limited companies qualify as micro-entities. Most of them pay an accountant £300–£800 a year to file straightforward corporation tax returns — returns that follow predictable patterns and can be automated end-to-end. SimpleCompanyTax exists to change that equation.
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. Not by cutting corners — by focusing scope and automating everything that can be automated.
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 — Full three-band corporation tax with marginal relief where applicable.
Everything is generated from a single guided session — no accounting jargon, no manual XML editing, no iXBRL tagging tools.
APPROACH
Compliance first. Focused scope. Transparent pricing.
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 for dormant companies and £25 for trading micro-entities. No hidden tiers, no upsells, no per-filing surcharges. Our focused scope allows us to automate 99% of the process and pass those efficiencies directly to customers.
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
- Companies with associated companies (complex marginal relief calculations)
- R&D tax credit claimants
- Group relief or consolidated accounts
- Multi-entity corporate structures
- 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 happily tell you so.
