If you knows that the payment to contractor will exceeds 100000 during the year then deduct TDS on each Payment to Contractor.
Or if you can't predict that payment would exceeds 100000 then don't deducd TDS till the time payment does not exceeds limit.
In future if that payment to contractor exceeds 100000 then deduct TDS on whole amount which you have paid till that time.
