Frequently Asked Questions
Why doesn't TinyTax file CIC accounts?
CIC accounts must be filed alongside the CIC34 community interest report, which is a Companies House-specific submission outside the standard third-party software channel. TinyTax handles the CT600 to HMRC; you file accounts and CIC34 directly with Companies House (their online portal or paper).
Where do I file CIC accounts?
Companies House WebFiling or paper submission. The CIC Regulator also receives a copy of the CIC34 report. TinyTax can't file these for you, but the CT600 side is fully supported.
What CIC types are supported?
CICs limited by guarantee and CICs limited by shares are both detected from Companies House data. TinyTax files CT600 for both — accounts route is the same regardless.
Do CICs pay corporation tax?
Yes. CICs are not charities (charities have separate tax exemptions) — they pay corporation tax on profits like any other limited company. The CT600 is the same form, filed via TinyTax.
