<prompt> Human: I have 95,000 in my business checking account from my side business. I have very few expenses and Id like to reduce my tax exposure by the end of the year. Im considering purchasing investment property although I dont think this fits my timeline for this year. I dont really have any ideas beyond that. Moving forward, my AR looks like it will be 90k per month starting in January. The problem persists with a high taxable gross sales and limited expenses.Any advice would be appreciated.  <response>: Solo 401k. Can contribute and subsequently lower your taxable income 18k 25 of your gross compensation.May want to query rsmallbusiness as well, though Id look into getting an accountant at this point.
