If you are able to make or increase deductible contributions to a retirement plan, it will reduce your current taxable income. It could be a traditional IRA, a traditional 401(k), or other tax-deferred plan. This defers, but does not eliminate, the tax. The money that you contribute to the retirement plan will become taxable income when you take it out of the plan.
Other than that, there is not much you can do to reduce the amount of your income that is taxable.
