I am seeking an experienced tax advisor (preferably licensed in CA) with strong expertise in US and German tax law, particularly in real estate investments, mixed income (W-2 & self-employment), and international taxation matters. 

@Nicole GrazianoI recommend that you have a consultation with a real estate tax accountant regarding your taxes.Bigger Pockets is a great place to find a real estate tax accountant. 

So, when Trump changes to no tax on tips I feel inclined to change my rental income structure.50% reduction in rent.Previous 50% made up from a mandatory nontaxable tip. 

I am seeking mentors and or guides to help me invest in business that can eventually help offset W2 income tax.

It is most likely 2025 income.

Insurance-  we had 18 months of full lost income coverage.  

We are in a very low tax bracket this year but should be 10% higher in 2025.

Interest income is interest income, unless you decided to roll some of the current cash into a self directed IRA at which point your interest income would be deferred for a later time and allow your funds to grow tax free.

I am in one of the higher tax brackets and could be saving around 40k~ a year on taxes with this.
