I have been paying installments on my flat since last December and for each installment, I have been filling out form 26QB and deducting TDS. My total consideration value is excluding GST. BUT the installments contain gst because the builder divided the whole amount including GST by 10 (because ten installments) and split it by 99% to him and 1% TDS. Now if I add up all the installments in the end (during the last payment), won't it exceed the total consideration value (because it excludes gst)? If so, is this a concern?

Also , to add to the complexity there is a blended gst here - 5% on the base value and 18% on the maintenance charges for 2 years.

Can someone please explain this to me! TIA.
