Payments are based on a percentage of earnings of workers which become an obligation, or [[debt]], of the United States government. The current rates are 15.3% -- half provided by the worker and half paid by the employer, which ''includes'' Medicare. No deduction or personal exemption is allowed, meaning the very first dollar of earnings is taxed. | Payments are based on a percentage of earnings of workers which become an obligation, or [[debt]], of the United States government.
