iXBRL tagging for software & tech companies
R&D claims, deferred revenue, share-based payments, group structures — software company accounts are rarely simple. We tag the detail correctly, including the CT600L supplementary pages R&D claims need.
Growing software companies outgrow "simple" tagging fast
A pre-revenue startup's first accounts are usually straightforward. A funded software company two or three years in rarely is — and the tagging complexity grows with the accounts.
R&D tax credit claims
R&D and creative industry tax credit claims need the CT600L supplementary page correctly tagged alongside your core computations — easy to get wrong if it's not done often.
Deferred & recognised revenue
SaaS and subscription revenue recognition creates note disclosures that need individual tagging, not just headline totals.
Share schemes & investment rounds
EMI schemes, share-based payment charges, and funding round disclosures all need to be mapped to the correct taxonomy elements.
This is what our full tagging tier is built for
Once your accounts include R&D claims, deferred revenue schedules, or anything beyond the standard primary statements, minimum tagging won't cover what HMRC needs for your computations. Our full tagging service maps every note, disclosure and comparative figure — the level HMRC requires for Corporation Tax computations regardless of company size.
- CT600 supplementary pages tagged alongside core computations
- Every disclosure mapped, not just primary statement totals
- Independent second review before delivery
Full tagging — £95 +VAT
Line-by-line tagging for HMRC computations or complex Companies House accounts.
Frequently asked questions
Does R&D tax credit tagging cost extra?
R&D and creative industry claims typically fall into our full tagging tier at £95 +VAT, since the CT600L supplementary page needs full mapping alongside your core computations — send your figures over for a fixed quote.
Can you tag deferred revenue and subscription disclosures?
Yes — SaaS and subscription revenue recognition notes are mapped individually as part of full tagging, not collapsed into headline totals.
We're about to close a funding round — does that change our tagging needs?
It can — share-based payment charges, EMI scheme disclosures, and funding round notes all need correct taxonomy mapping. Send us your accounts once the round has closed and we'll confirm what's needed.
