Do I need to fill up a form or pay for a tranit visa (visa on arrival) at the HK airport althogh I don't need a visa to visit HK?

I am an Indian national and I understand that I dont need to apply for a visa to stay in HK for 14 days or less. But would that mean I have to complete some formalities in the airport... like filling up a form or paying for a tranit visa (visa on arrival).

Thx.
