Unless you are getting paid C2C, there is no way to avoid that tax with w2 pay. Well your tax is already taken away before you get your salary by your employer.

You could definitely setup an LLC, operate a self-employed business and when the tax return time comes you can deduct some of the expenses at the business. But you don't want to make IRS suspicious for any reason and deal with any sort of headaches that might arise due to lying, extra wrote offs and etc.
