Client - MTD Nominal Mappings

Mapping a client's chart of accounts to the boxes of an MTD Income Tax quarterly update, per income source, and pulling the cumulative period's figures from their connected books into a draft for review. Before anything is confirmed the mapping is a suggestion built from the platform's shipped catalogue crossed with the client's live chart; ambiguous accounts are left blank rather than guessed. Figures never leave here for HMRC — the quarterly-updates save and submit path does that — and disallowable expenses are never filled in, because a chart of accounts has no concept of the split.
