Build the reserve

Use one currency and one tax period. Do not enter taxpayer IDs, account numbers, client names or invoice details.

Arithmetic contract

All amounts are user-entered. Credits reduce the planning reserve but never below zero. Instalments only split the reserve evenly; they are not official due dates.

Privacy and tax boundary

No input is stored, put in a URL, sent to analytics, AI or an API. This plan is not a return, assessment, tax opinion or proof that an expense is deductible.
