 2012 Federal Payroll Tax Tables and Rates (Notice 1036 - 1/5/12)
Federal Tables are updated annually by the Internal Revenue Service, generally in December. The Federal Tables posted here are the inputs for the percentage method formulas used to calculate Federal withholdings from wages earned. These tables are imported into a transaction file when setting Payroll preferences by using the Import... button on the Tax Tables panel.
A table only needs to be imported once, tax data is saved with the transaction data.
