MTD ITSA means quarterly updates, an end-of-period statement and a final declaration — roughly five service events a year where there used to be one. If your fees stayed annual, you're giving the extra work away. See what your client book is worth priced properly.

The unpriced quarterly work across your affected client book, annually.
Sole traders & landlords over the MTD ITSA income threshold — quarterly filers now and from April 2027.
What you charge each of them today, on the old annual model.
The extra the quarterly workload justifies — five filing events vs one. Set it to your own judgement.
Quarterly updates, an end-of-period statement and a final declaration replace a single annual return. Firms that hold annual prices for quarterly work absorb the cost in unpaid evenings. Engage assesses each client against the thresholds, builds the correctly-priced proposal and the updated engagement letter — so the repricing actually happens, at scale, before the April 2027 wave prices it for you.
MTD ITSA volumes: ~780k clients in quarterly filing since April 2026, ~970k more from April 2027 (gov.uk). Uplift is your judgement of what quarterly work is worth — the tool does the maths, not the pricing decision. Indicative, not advice.
