This might be useful you're finalising your tax return and looking for cheap tax report for your crypto assets. In the past few years, I've relied on using the free Koinly pro subscription codes but I think they are no longer available this year unfortunately. Was looking at other alternatives but they are still quite pricey (at least for my circumstances).
Not sure if it works for other plans - I just went straight ahead with the Newbie plan as it was more than enough for me. You definitely need higher plan if you have more than 100 transactions in the past FY.
Edit: looks like the code provides $40 flat discount across all plans (credit @greenslade)
Edit (2): YMMV you might get either $40 or $50
I'm being offered $29, not $19. Consistent 40 AUD discount across all plans. Is that because I clicked for a referral code, or is the OP incorrect?
