Payment Issues in recurring payments and deductions

Hi All,

I am facing some problems with recurring payments and deductions

1. 1. Uniform Allowance- Once in Year- January only once.

Regarding uniform allowance,  I have created I payment model  TEAL and assigned deduction period January Month and run the  pay roll it is working fine.But when again I tried to assign January month it is not taking.

Further, every month it is adding the payment.  ( It suppose to pay only once in a year) or in some cases twice in a year.

1. 2. Other Allowances – Once in every quarter

How to assign

1. a. Is this payments are eligible for tax calculation?
2. b. How to upload the data of this kind of payments and deductions to system for some 140 employees?

Please help me.
