You are a CPA being paid for a tax return for a client who just started a new job. Your client is attempting to fill out Form W-4 and has asked for your help. He would like to receive a large refund when he files his return and would like to claim as few allowances as possible. Even though he is married and has four children, he is planning on claiming no allowances. What would you tell your client? Do you agree with this financial planning strategy? Why are large tax refunds considered giving the government an "interest-free loan"?
