Any increase in the registration fee under gst

No effect over stamp duty & registration charges of immovable properties, as these are out of direct purview of GST.

" But if purchasing directly from builders / developers than local vat & service tax will be applicable"

Before implemetation of GST : ST & VAT after GST: CGST & SGST with almost same percentage. But here query is effect of GST w.r.t. registration charges: no effect.

Thanks for the response and clarification..
