Go through the last year’s tax return
You need to have a look at the front side of last year’s tax return. On form 1040, the first part shows all the sources of income that your were taxed on. If any amount of money is listed on the right side of that row, then your social security income is taxable; however, the modified adjusted gross income has to be $25000 or more if you file it individually. If you file your tax jointly, then it has to be $32000 or more.
Reallocating the investments
If you have taxable investment income like interest, dividends or capital gains, you can reallocate those investments into tax-free accounts or other kind of investment, which should help you get rid of the taxes.
Selling the investments to lower the income
One way of avoid paying tax on your social security is to sell your taxable investments and buy them back inside a traditional IRA. Keep in mind that you do not have to sell all your investments. Just sell them to an extent that your income is lowered and your social security is not taxed.
