Hello - using a friends motorbike and she asked me to help her pay the taxes on it. They havent been paid in a few years as she has been out of the country since before COVID - the sticker says 2561.

Does anyone know if the transport office makes you backpay all the years or just this current year to update the road tax? Dont want to get in trouble or pay a huge fine!

Thank you kindly if you have some accurate information 🙏
