What are all the ways I can reduce my taxable income?

34/m, make about 250-300k/yr and I want to lower my taxable income.

Not sure if this is the right sub, but I max out my 401k, backdoor Roth, etc.

I'm trying to find ways to lower my taxable income. Would love to hear ideas from the smart people here on what to do.

Edit: other than asking my employer to reduce my salary 😆
