Employee participants can choose to contribute 3%, 4%, 6%, 8% or 10% of their gross pay, and can switch rates three months after setting a rate (unless employers agree to a shorter time frame). These contributions are deducted from an employee's pay and sent by the employer to Inland Revenue alongside their PAYE tax returns. The self-employed and unemployed can choose how much they want to contribute; while most KiwiSaver schemes have minimum contribution amounts for people in this category, several schemes allow any level of contributions. All eligible participants aged 18 to 64 starting a new job, with some exceptions, are automatically enrolled in KiwiSaver. New employees can choose to opt out from day 14 to day 56 of their employment.
