Answer 1

ALTER PROCEDURE taxable_varsalary

 @emp_code bigint,
 @co_id bigint,
 @t_varsalary decimal(8,2) OUTPUT

AS

   select @t_varsalary  = sum(tran_value) 
   from emp_ded_ben_trans 
   where emp_code=@emp_code and co_id=@co_id and period_flg=2 and tax_flg=0

The return value for a stored procedure has to be an int. Use an output parameter instead or select it

Answer 2

A stored procedure return only returns an integer, either use an OUTPUT parameter or do a SELECT at the end

Answer 3

Create a Scalar-Valued Function:

CREATE FUNCTION taxable_varsalary
    @emp_code bigint,
    @co_id bigint
RETURNS DECIMAL(8,2)
AS
declare @t_varsalary decimal(8,2)

set @t_varsalary  = (select sum(tran_value) from emp_ded_ben_trans where emp_code=@emp_code and co_id=@co_id and period_flg=2 and tax_flg=0)

RETURN @t_varsalary
