iXBRL tagging for SMEs
FRS 102 accounts and CT600 computations, tagged as a matched pair — the most common filing profile in the UK, done right every time.
The most common filing profile in the UK
Most UK companies are SMEs filing FRS 102 accounts alongside a CT600 — two documents, tagged as a matched pair, validated against both the HMRC and Companies House taxonomies. It's routine work for a specialist, but it's exactly the kind of work that goes wrong when it's done occasionally rather than every filing season.
What typically needs tagging
- Balance sheet, profit and loss account, and notes for Companies House
- Full tax computations and accounts for the CT600
- Any supplementary CT600 pages your specific circumstances require
Where this sits in our pricing
Most SME filings fall into our full tagging tier at £95 +VAT, with the combined CT600 & computations package at £140 +VAT when both documents need tagging together.
Frequently asked questions
Do all SMEs need iXBRL tagging?
Yes for CT600 — every company with a Corporation Tax return obligation needs iXBRL-tagged accounts and computations, regardless of size. Companies House currently accepts some non-iXBRL formats too; see our Companies House iXBRL guide.
What's the difference between minimum and full tagging for an SME?
Minimum tagging covers straightforward Companies House-only filings. Full tagging — required for CT600 attachments — maps every note and disclosure, not just headline figures. See our services page for the full breakdown.
How long does tagging take for a typical SME filing?
Standard turnaround is 24 hours once we have your draft accounts, with a faster express option available if your deadline is close.
