If someone has used your social security number fraudulently you should immediately contact the Social Security Administration, toll-free at 800-772-1213. You should also report the unauthorized use to your state taxing authority, both income tax and sales tax, as well as your local police authorities regarding identity theft. This is a major matter, not an inconvenience and you should not delay at all.
