From the start of the scheme until May 2015, those who joined KiwiSaver received a $1,000 tax-free "kick start" to their KiwiSaver account from the government. The Fifth National Government removed it effective from 21 May 2015 as part of its 2015 budget. Those aged 18 and over also receive from the government a "member tax credit" (MTC) of 50 cents per dollar contributed (or part thereof) for the first $1,042.86 contributed per year (1 July to 30 June). The MTC is not a true tax credit; it is a monetary contribution paid by the government via Inland Revenue, mainly to offset the tax paid on interest earned. Those withdrawing KiwiSaver funds to help buy a first home may also get a deposit subsidy of up to $5,000 (existing homes) or $10,000 (new builds) from Housing New Zealand, provided they meet the required income, deposit and house price requirements.
