Cheapest Company Tax Return (CT600) software, by checked price
This page lists the 16 company filing products we compare by one thing only: what a trading company would pay for a year of filing with each one, using the cheapest plan a single company can buy, lowest first. We read every price on the provider’s own site on the day shown. A monthly price counts for 12 months, and where a provider quotes a price without VAT, we add VAT at the standard rate before sorting, so every price is compared on the same footing. Products at the same price sit in alphabetical order, and nobody pays for a place.
The cheapest is not always the right choice for your company. Some of these prices cover the Company Tax Return alone, so your accounts may need other software or a separate fee, and some assume you already have accounts in the iXBRL format, so we say beside each product what its price covers. Products marked Company Tax Return only are on HMRC’s list but not on Companies House’s list of software for accounts, which matters for your accounts from 1 April 2028, as the comparison table explains. How we compare products explains how we check each price.
