Not rich enough for financial advice but getting increasingly overwhelmed trying to manage money?

I wonder if any other young(ish) or early career HENRYs can relate. I am 25 years old and £150k total comp this year.

Is anyone else absolutely overwhelmed with the seemingly endless labyrinth of tax rules, student loan repayments, NI, pension, salary sacrifice, etc etc etc … I feel so incredibly fortunate to have a comfortable lifestyle where I can also save, but as I approach >£60k in savings it’s getting more and more confusing and difficult to know how to avoid getting retaxed on earnings 2 or 3 times!

Can anyone else relate to this sort of in between stage and how you avoided going mad?

Btw I enjoy living in the UK and am more than happy to stay here— just want to make the best of it!

Edit:

Thanks everyone - seeing lots of the same advice so feel like I am on the right track more or less. Overall takeaway is not to get too lost in the details!
