Spouse contributions are non-concessional contributions made by a person on behalf of their spouse. The contributor can claim a tax rebate of 18% (up to $540) for the first $3,000 of spouse contributions made, provided the spouse has an assessable income of $37,000 or less.
Over this threshold, the rebate reduces by 18 cents for every $1 of income and reduces to $0 where the spouse’s income is greater than $40,000.
The amount you contribute will count towards the receiving spouse’s non-concessional contributions cap and the receiving spouse will need to have a super balance below the total super balance cap to receive the contribution.
