New Improved Effective Tax calculator
There is now a new improved "effective tax rate calculator" see sidebar link to activate. This performs all calculations for Income, Benefit (DPB or unemployment), Family Support (including Child Tax Credit), Accommodation Supplement and Student Loan repayment. All figures are calculated for the fiscal years 2005, 2006, 2007 and 2008 and are compared withwhat they woud be with a zero income. The final (take-home) income is calculated as Income+Benefit-Tax+Family Support+Accommodation Supplement-Student Loan Repayment, the net value of work is calculated as the difference between Income+Benefit-Tax+Family Support+Accommodation Supplement using the actual Income or setting Income to zero. The effective tax rate is calculated by scaling the value of work against actual income.
I've also created a link to a pdf document which uses this sort of analysis to highlight the inequities in NZ's present system and to suggest improvements. I also e-mailed this document to all the parties in parliament at the time (Maori Party weren't and I couldn't find an EMail address and have received replies from Labour and NZ First.
