AI TaxPilot keeps your company details in sync from Companies House, builds FRS 105 (or FRS 102 §1A) accounts from your bank feed, files the iXBRL to Companies House, and drives your confirmation statement from the same record.

Frequently asked questions
Can AI TaxPilot file my accounts to Companies House?
Yes — it builds FRS 105 or FRS 102 §1A accounts from your bank feed, tags them as iXBRL, and files them to Companies House.
Does it do the confirmation statement (CS01)?
Yes — it syncs your company details from Companies House, lets you confirm or update them, and files the CS01, driven from the same record as your accounts and CT600.
Which accounts standard will it use?
It checks your company size and picks FRS 105 (micro-entity) or FRS 102 §1A (small) automatically — you can override it.
When are company accounts due?
Nine months after the financial year end for a private company (21 months after incorporation for a first set), with automatic penalties for late filing.
