Ask Rusty – Will My Social Security Benefits Ever Be Non-Taxable?

Published 12:01 am Sunday, February 6, 2022

Dear Rusty: If we take our Social Security at our full retirement age (66 years and 6 months for both of us) and we both continue to work, what are the income tax consequences? Is there an age at which we can still work and draw Social Security without tax consequences on our benefits? Signed: Overtaxed Couple

Dear Overtaxed Couple: Regardless of when you claim your Social Security benefits, whether those benefits are subject to federal income tax depends entirely upon your income as reported to the IRS. This is true even if you collect Social Security benefits after you reach your full retirement age – there is no age at which SS benefits become exempt from Federal Income Tax. Here’s how it works:

Taxation of your Social Security benefits depends on two things – first, the amount of your combined income from all sources (known as your Modified Adjusted Gross Income or “MAGI”) and second, your income tax filing status (whether you file your income taxes individually or jointly as a married couple). Your “MAGI” consists of your Adjusted Gross Income (AGI) on your income tax return, plus half of your Social Security benefits received for the tax year, plus any other non-taxable income you may have had.

If your MAGI for the tax year exceeds certain thresholds, then some of your Social Security benefits are taxable at whatever your normal IRS tax rate is. If, as a couple, you file your income taxes as “married-filing jointly,” and your MAGI is over $32,000, then 50% of your Social Security benefits received during the tax year becomes part of your overall taxable income at whatever tax rate is standard for your income. But if your MAGI as a couple for the tax year exceeds $44,000 then up to 85% of your SS benefits becomes part of your overall taxable income. If your MAGI as a married couple is less than $32,000 then your Social Security benefits aren’t taxable.

For those who file their federal income taxes as a single the thresholds are lower. If your MAGI as a single filer is $25,000 or less, your Social Security benefits aren’t taxable. However, if your MAGI as a single filer is more than $25,000, then half of your Social Security benefits received during the tax year becomes part of your overall taxable income, and if your MAGI as a single filer is more than $34,000 then up to 85% of your benefits for the tax year becomes part of your taxable income. But a word of caution for those who are married but choose to file taxes “married – filing separately”- if you file separately and live together at any time during the tax year, the threshold for taxation of Social Security benefits is zero.

So, Federal taxation of your Social Security benefits depends entirely upon your combined income from all sources and your income tax filing status – your age doesn’t come into the picture at all, even if you are collecting Social Security benefits after your full retirement age. Be aware, however, that a dozen U.S. states levy an income tax on Social Security benefits, so you should check the tax laws in your state of residence to see if some or all your Social Security benefits will be taxed by the state you live in.
