Rachuba by Wisent
Payroll for a company with one employee
Rachuba computes each paycheck from gross to net with the published federal and state tables, records every run in a ledger you keep under version control, and tells you what to deposit, where, and by when. It also projects the employee's own federal return, so the estimated tax still owed and the worth of each retirement choice are known before the year closes.
