Rto — Charging more tax in BH series number

I have bought Tata Nexon from Kota, Rajasthan whose invoice generated on on 31st December 2021 having ex-showroom price 9.99 lacs. Dealer has applied for 'BH number' registration on 5 February 2022. The price of the vehicle was increased on 18th January 2022 from 9.99 Lacs to 10.09 Lacs. As per Gazette notification, CG-DL-E[protected], NEW DELHI, FRIDAY, AUGUST 27, 2021/BHADRA 5, 1943 motor vehicle tax should be calculated on 'Invoice price excluding Goods and Services Tax (GST)'.But when Dealer registered for BH number in RTO Chittorgarh, the Motor Vehicle (MV) tax imposed on me was 10%(i.e. on price 10.09 Lacs) plus late fees from 31st December 2021. The ideal tax should be on invoice price excluding GST. Dealer is not helping saying its RTO automatically taking higher value.
