The correct answer is A, Tax deferral. Both qualified and nonqualified retirement plans share the feature of tax-deferred growth, meaning that earnings within the account are not taxed until they are withdrawn.
Step-by-step, in qualified plans (such as 401(k)s), contributions are often made with pre-tax dollars, and taxes are deferred until distribution. In nonqualified plans (such as annuities or certain deferred compensation plans), contributions are typically made with after-tax dollars, but the earnings still grow tax-deferred. This shared feature is the key similarity between the two types of plans.
Choice B, tax deduction, applies mainly to qualified plans, where contributions may be tax-deductible. Nonqualified plans generally do not offer this benefit. Choice C, nondiscrimination, is a requirement only for qualified plans to ensure fairness among employees and prevent favoring highly compensated individuals. Choice D, creditor protection, is typically stronger in qualified plans under ERISA, but not consistently available in nonqualified plans.
Therefore, the only characteristic common to both qualified and nonqualified retirement plans is tax-deferred growth, making Answer A correct.
