234a b c allowed as deduciton

Deduction on interest always allowed on paid basis. So in this case deduction for interest is allowed in fy14-15

As per Section 43B CERTAIN EXPENSES ARE DEDUCTABLE ON PAYMENT BASIS-

a. "Any sum payble by way of tax, duty, cess or fee (by whatever name called under any law for the time being in force)....." 

Interest under section 234 A/B/C is not allowed as a deduction as per section 40a(ii). Though there have been recent cases to the contrary, however, it is advisable to not go with those cases and instead disallow them to avoid litigations.
