Regards Section 89, when I am calculation the previous years tax along with adding current year arearrs, do I just have to calculate normal tax as per slab or I have to add the interest under section 234 etc (because I think not to be added interest as I dint receive the arrear that year so thats why extra tax not paid so why interest in question) please clarify
