This page reduces the pre-submission guesswork: what to upload first, what can follow later and what must be complete before filing.
For most iXBRL filings, start with final or near-final statutory accounts, the tax computation, CT600 data if available and any prior-year iXBRL file for rollover. If something is missing, we can often begin a readiness review, but final filing needs complete approved accounts and filing context.
AA02 or dormant accounts, company number, year end and confirmation of dormant status.
Micro-entity accounts, balance sheet, notes where included and entity details.
Accounts, basic notes, directors report where applicable and supporting schedules.
Full accounts, all notes, directors report, auditor report if applicable and tax schedules.
Group accounts, subsidiary accounts, consolidation schedules and intercompany support.
IFRS accounts, ESEF context where relevant and supporting review evidence.

SORP-based accounts, trustee report, notes and restricted fund information where relevant.
