Do I get any tax savings by doing all my investments through an S corporation vs personal account?

Last year as I sold some mutual funds I had to pay a lot of taxes on capital gains and every year I find myself paying taxes on dividends for stocks I own. Can I simply open an S Corporation and invest my funds through that? I can then offset gains with corporate expenses.

As lovely an idea that it, no it won't avoid any taxes. The only way to avoid the capital gains or ordinary income taxes on ivestments is for you to invest in a tertirement account like an IRA or Roth IRA or employee benfit plan.

It sounds like you own a business. Speak with your CPA to find out which plan is best for you. SOme examples are

SEP
Simple SEP
Simple IRA
Simple 401k
Roth IRA
Traditional IRA

AS you can see, there are alot of choices. Each one has its benefits and srawbacks. Some are tax free and some are just tax deferred until retirement.

If these plans arent an option for you, look into index funds, they typically have low if not any turnover.

Turnover=capital gains=taxes

Good luck
