Tax reserve & financial planning
This topic covers a Premium-tier capability in the full Play Store N78-Ops release. It is not included in N78-Ops Community Edition (Basic tier).
The tax reserve line (30%) appears in Business status on Premium and is a conservative estimate to help you set aside funds for taxes. It is based on your net profit (revenue minus expenses) where the screen shows it. You can change the rate under Tax & pricing → Federal tax reserve.
