How capital is recovered
A four-step loop: discover activity, secure evidence, organize to program rules, sustain across filing cycles.
Step 01
Connect
Connect the systems TaxCalc already supports (engineering, finance, or payroll sources named on the vendor site) so eligible activity is visible without reconstructing year-end spreadsheets from scratch.
Step 02
Qualify
Surface candidate projects and spend against the programs TaxCalc markets for (Merged RDEC), with human review where the vendor includes expert checks.
Step 03
Document
Produce claim-ready narratives, cost schedules, and evidence packs structured for the administering authority's filing or enquiry posture.
Step 04
Sustain
Keep contemporaneous records across filing cycles so next year's claim is not a scramble, and so audit trails stay traceable.
