He Collects Toyota Dividends at 66 While Drawing Social Security. His Checks Won’t Shrink, Yet Up to 85% Could Become Taxable

Take a hypothetical 66-year-old retiree. He’s single, owns shares of a Japanese car maker in a taxable brokerage account and gets a Social Security check every month. On November 5, Toyota (NYSE:TM | TM Price Prediction) said it plans to return up to $89 billion to shareholders through March 2031 in dividends and buybacks.

The same day, Toyota raised its earnings forecast, and the stock had its biggest gain in several decades. Shares are up about 11% over the past week, to around $216. For our hypothetical retiree, the development raises a practical question: can more dividend income cost him part of his Social Security check? Social Security applies separate rules to his monthly check and to the tax on his benefits.

Why Dividends Can’t Touch His Monthly Check

Assume he was born in 1960, which makes him eligible for full benefits at 67. People who collect before that age face the retirement earnings test. In 2026, it holds back benefits once earnings go above $24,480.

That test counts only wages and net self-employment income. It ignores dividends, interest and capital gains completely. He could collect $5,000 or $50,000 in dividends, and Social Security wouldn’t withhold any of his benefits because of that income. In January, that check also gets a 3.6% inflation adjustment.

Where 85% of His Benefits Become Taxable

Taxes work differently. The IRS uses what’s called combined income: adjusted gross income (AGI), plus tax-exempt interest, plus half of Social Security benefits. For single filers, up to 50% of benefits become taxable once combined income passes $25,000, and up to 85% once it passes $34,000. Those thresholds don’t rise with inflation.

Say he gets $24,000 a year from Social Security and $50,000 in taxable dividends from a portfolio that includes Toyota. He has no other income. Half his benefit is $12,000, so his combined income comes to $62,000.

Plug that into the federal formula, and $20,400 of his benefits becomes taxable. That’s 85%, the most the law ever counts. To be clear, 85% is the share of his benefits added to taxable income. His actual tax rate is set by his bracket. The $20,400 raises his AGI to about $70,400, and his bill depends on his deductions and how much of his dividends qualify for lower rates.

He also gets the new $6,000 senior deduction, which is available to people 65 and older. It starts shrinking once modified adjusted gross income (MAGI) passes $75,000, so he keeps all of it. One retiree recently told another online that under the new tax law, “The 85% rule doesn’t apply anymore.” The rule still applies. The deduction brings down his taxable income, but the formula for taxing benefits hasn’t changed (it’s one of several subtle IRS rules we charted in a free retiree tax trap guide).

Buybacks and Dividends Reach His Tax Return Differently

Toyota’s $89 billion figure counts buybacks as well as dividends. When Toyota buys back shares, there are fewer shares left. That can push the stock price higher and increase his ownership stake without creating any taxable income for him. Dividends show up as cash and are reported on Form 1099-DIV.

Toyota pays dividends twice a year. Its interim dividend of 50 yen per Japanese share pays on November 26, and the company expects 100 yen for the full year, a yield of about 3%. Each U.S.-listed Toyota share represents 10 Japanese shares, and payment timing for American investors can differ. Japan usually deducts tax before the money reaches U.S. holders. He can generally claim a foreign tax credit, but the full dividend, before deducts, still counts toward his income.

Only gains from actually selling shares count toward combined income. He’s already at the 85% cap, so selling won’t make more of his benefits taxable. A large gain could still push his income above $75,000 and start shrinking the senior deduction. At much higher income levels, it could also trigger Medicare premium surcharges. For 2026, those begin above $109,000 for single filers, although the thresholds change each year.

Two Calculations Worth Keeping Apart

Mixing up the earnings test with the tax on benefits leads to costly mistakes, like selling a solid dividend stock to protect a check that was never at risk.

Timing matters most for retirees below the cap. In that range, every extra dollar of dividends or gains can pull more benefits into taxable income. Once someone reaches the 85% cap, as he has, extra income can’t make any more of his Social Security taxable. Dividends and capital gains may still qualify for lower tax rates. Another option is to ask Social Security to withhold federal tax using Form W-4V, which spreads the cost across the year and helps avoid a big bill in April.

Filing status, state taxes and the mix of qualified and ordinary dividends all vary from one person to the next, so the same $50,000 in dividends can produce a different tax bill for someone else.
