Code:

     , sum(t.tax)    as TAX
from (
       select sum(salary)
            , sum(basic)
            , sum(tax)
         from table1
     union
       select sum(salary)
            , sum(basic)
            , sum(tax)
         from table2
      ) as t

Probably it should be an UNION ALL so that duplicates are retained.
