Hi Katrina,
Thanks for posting in the Community!
I understand you're only seeing subclass 417 and 462 in the tax calculation option when selecting Is approved for holiday maker. At the moment, we're unable to recommend what option to choose in the tax file declaration settings. I would recommend contacting directly the ATO to verify what is the correct tax calculation options for this subclass.

Post again in the Community if you have other payroll concerns. I'm around to assist you.
