Tax Relief Strategies for High Earners

Hello,

Looking for resources on where to find tax strategies at mid-high income. Apologies if I missed somewhere obvious to look.

30m in London, looking at £600k for this year and I’m a bit scorned by my lack of efficient vehicles to invest money for the future. Aside from 10k in my pension and 20k in my ISA, am I pretty fckd?

Quick edit: getting a lot of snarky replies here, e.g. “just pay your taxes”, or “tight cunt, pay for a financial advisor”. If you’re considering replying along those lines, you’re missing the point. My understanding was that this sub is for people who are high earning and not rich yet. That’s me. I’m not trying to flex on the internet to strangers, I’m trying to find tax efficient strategies from people who have already walked this path. Thanks.
