RESPA RESP is a savings plan for post-secondary education which allows funds to accumulate on a tax-deferred basis up to certain limits. There is no annual limit for contributions. For each beneficiary the lifetime limit on contributions is $50,000. Although there is no tax deduction, the interest and income earned within the plan is sheltered, which means that the tax is only payable on the funds withdrawn to fund the student’s education. And it is taxed at the student’s low rate.
