Can I file micro-entity accounts myself?

By DormantFile · Updated 1 June 2026

Yes — there is no rule that micro-entity accounts must be prepared or filed by an accountant. As a director you can file them yourself, the same way you could file dormant accounts.

The question is whether it's practical. FRS 105 micro-entity accounts have to be submitted to Companies House as an iXBRL document — a machine-readable file with the figures tagged to the FRS 102 taxonomy. Companies House WebFiling can handle simple cases, but the tagging is where most people get stuck.

It comes down to how complicated the accounts are:

• A non-trading company whose only activity is a loan being repaid (such as a Bounce Back Loan) has a short, predictable balance sheet. This is exactly what DormantFile does: you enter a few figures, we build the FRS 105 iXBRL and submit it directly to Companies House, with a nil CT600 to HMRC if needed. From £19/year.
• A trading company, or one with income, assets, or anything unusual should use an accountant — there are judgement calls that software shouldn't make for you.
