here are the types of WT's which gets involved in the tax calculation.

when you run the payroll driver program along with a schema, the U000 schema has subschema UTX0 in which you call the BSI which calculates the taxes for you.

here you have to send /3xx and /6xx WT's. once BSI calculates the taxes it will send the taxes amount back to SAP by storing the actual tax amount in /4xx.

below is the description of the WT which are invloved in the tax calculation.

/ 3xx = gross pay

/6xx = gross pay u2013 deductions

/7xx = taxable amount

/4xx = withholding amount

Where xx defines the tax types

01 = federal tax

= state tax

03 = EE social security tax

04 = ER social security tax

05 = EE medicare tax

06 = ER medicare tax

here there are some tax tables which you have to look at it when you do payroll configuration.

T5UTT: contains tax types.

T5UTD: assigning tax types per tax authority.

T5UTB: work tax areas.

T5UTA: resident tax areas.

T5UTH: Tax number u2013 BSI INTERFACE

T5UTL: tax company

T5UTM: tax model

T5UTS: states without withholding tax.

T5UTY: Tax type combinations

therefore you dont have to worry about the tax calculation, because BSI takes care about it.

hope this explanation gave you some understanding.

reward points if helpful.
