The Home Buyers' Plan (HBP) is a program that allows eligible first-time home buyers to withdraw up to $35,000 from their registered retirement savings plans (RRSPs) to buy or build a qualifying home without paying any tax on the withdrawal. The withdrawn amount must be repaid to the RRSP over a period of up to 15 years, starting from the second year after the withdrawal. If the required repayment for a year is not made, it is added to the taxpayer's income and subject to tax. Therefore, option B describes a feature of the HBP. The other options are not correct descriptions of the HBP. Option A is false because to qualify as a first-time home buyer, you or your spouse must not have owned and lived in another home as your principal place of residence during the four-year period before the date of withdrawal. Option C is false because a qualifying home must be purchased or built before October 1 of the year following the year of withdrawal. Option D is false because if you have a spouse or common-law partner, each of you can withdraw up to $35,000 from your RRSPs, not $50,000.
