Does TinyTax Handle Self Assessment Tax Returns?

TinyTax is a filing tool for UK limited companies. It handles corporation tax (CT600) returns and Companies House accounts — not personal Self Assessment.

What TinyTax Files

TinyTax supports:

  • CT600 — the annual corporation tax return, submitted to HMRC
  • Companies House accounts — statutory micro-entity accounts in iXBRL format, filed electronically to Companies House
  • Tax computations — generated automatically from your figures
These filings are required annually by every UK limited company, whether trading or dormant.

What TinyTax Does Not File

TinyTax does not handle:

  • Self Assessment (SA100) — the personal tax return for individuals and sole traders
  • Partnership returns (SA800)
  • VAT returns (MTD VAT is a separate service for registered companies, not personal SA)
  • PAYE / payroll
If you are a sole trader, freelancer, or individual who needs to submit a Self Assessment return, TinyTax is not the right tool.

Filing for Multiple Companies

If you need to file CT600 returns for several limited companies, the Portfolio plan covers multiple companies under a single annual subscription — you do not pay per company. Visit https://tinytax.co.uk/pricing to see the current price and explore the software for free before subscribing.

Self Assessment Alternatives

For personal Self Assessment returns (SA100), options include:

  • HMRC's free online service — suitable for straightforward returns, available at gov.uk
  • GoSimpleTax, TaxCalc, or Capium — commercial software suited to agents handling multiple SA returns
  • An accountant — for complex returns or large volumes
