Income Tax Calculations

Hi Folks

My Project is going Live on July 2006. Regarding Income tax i would like to upload all the Master data and Salary data effective 1-Apr-06 and would like to run the payroll manually for three months(April, May and June)by changing the Control Record.

I do not want to go for mid year Go-Live.

If i run Payroll Manually for three months manually the Income Tax is getting calculated from April itself where in Actual go live is only from July and i would like to deduct the system for Income Tax from July only.

How to make the system to calculate Income Tax only from July when i run Payroll manually from April.

Appreciate any help or Any other idea to make the system to work fine.

Regards

Ragavan
