What happened
DataTracks Nova is preparing UK micro-entity accounts and Corporation Tax returns, producing the iXBRL format required by HMRC and Companies House. Nova replaces the functionality previously provided by the closed CATO service. This software is also built to meet requirements when Companies House moves accounts filing to commercial software on April 1, 2028.

Why it matters
CATO, a free HMRC online service, was closed on March 31, 2026, requiring smaller UK companies to generally use commercial software for tax returns since April 1, 2026. The shift to commercial software and the required iXBRL format for 2028 represents a major regulatory change for UK businesses.
