TRF
From XFamily - Children of God
Tither's Report Form (or TRF) is a monthly, required report sent World Services by every Home along with their tithes.
This report was previously a paper form sent via post, however, it is now done electronically with a software program called teleTRF. This report requires detailed accounting of all income, expenses, member's personal information, proselytising statistics, etc. Failure to send this report to World Services could result in excommunication.
David Berg insisted that tithable "income" constituted the entire income before tax, (perhaps unaware of countries where tax rates can run at 50+%). He warned of severe punishments by God for those who did not tithe.
