Ask HN: Has anyone built a tax simulation environment?

Was curious if anyone had attempted such endeavour. The use case I see is you input your finances (eg. money spread over different investments, in a business, multiple incomes, etc.) and your goal (purchase home that costs $x) and an optimizer will try different solutions (eg. sell these assets for this tax liability, take this mortgage at this rate, pay it in lump sums to be able to withdraw assets from your business as dividends spread over N years, etc.)
