Spent it last year, so nothing. If you get a big return, you paid too much in and thats why its called a refund. Theres no law saying you have to loan the government interest-free cash each week. You only have to be paid up with them once a year anyway. Give yourself a raise by adjusting the amount that is taken out of your check to closely match the actual tax requirement and forget about the fat wad of (your own) cash at tax time. Its like paying $500 for a $300 tire and saying "Just mail my change to me next year". Mine comes out + or - about a hundred bucks each year, once state and federal are both figured.
