The Crucial Role of Taxes in Your Retirement Income

Generating an extra $1,000 a month is wonderful, but it’s important to remember that Uncle Sam will want his share. The amount of tax you pay on your new income stream depends on its source, and it can also affect how much of your Social Security benefits are taxed.

How Social Security is Taxed

Many retirees are surprised to learn that a portion of their Social Security benefits may be taxable. Whether they are, and how much, depends on your provisional income. This is a specific calculation used by the IRS.

Your provisional income is your Adjusted Gross Income (AGI) from your tax return, plus any non-taxable interest (like from municipal bonds), plus one-half of your Social Security benefits for the year. For the 2024 tax year, if your provisional income as an individual is between $25,000 and $34,000, you may have to pay income tax on up to 50% of your benefits. If it’s over $34,000, up to 85% of your benefits may be taxable. The thresholds are different for married couples filing jointly.

Therefore, a new $1,000 monthly income stream ($12,000 per year) could easily push you into a higher threshold, increasing the tax on your Social Security. It is crucial to account for this. You can find more detailed information on the official Social Security Administration website.

Managing Your Tax Bill

You don’t want to be hit with a large, unexpected tax bill when you file your return. One way to manage this is through tax withholding. Just as your employer withheld taxes from your paycheck, you can arrange to have taxes withheld from your retirement income sources.

For Social Security, you can voluntarily request that federal taxes be withheld from your monthly payments. You do this by completing Form W-4V (the “V” stands for Voluntary) and sending it to the SSA. You can choose to have 7%, 10%, 12%, or 22% of your total benefit withheld. You can find this form and instructions on the IRS website.

The type of account your income comes from also matters. Withdrawals from a traditional IRA or 401(k) are generally taxed as ordinary income. Dividends from stocks can be “qualified” or “non-qualified,” each with different tax rates. Withdrawals from a Roth IRA or Roth 401(k) are typically tax-free. Strategizing which account to pull from can have a significant impact on your overall tax bill.
