A portfolio that throws off $60,000 a year sounds like a finished puzzle. The brokerage statement says $5,000 a month, the bills get paid, life goes on. Then the retiree adds up what actually reached the checking account and discovers the spendable amount is thousands of dollars lower than expected. Taxes, Medicare costs, and inflation all take their share before that income can be spent.
The case of the missing $15,000
Four suspects sit at the table: the IRS, the state, Medicare, and inflation. Taxes and Medicare reduce the dollars available to spend today. Inflation attacks from a different direction, reducing what those remaining dollars can buy in the future. Together, they create a much larger drag on retirement income than most investors realize.
The IRS does not tax all yield the same
Federal treatment depends entirely on what produced the income. Qualified dividends from Johnson & Johnson (NYSE:JNJ | JNJ Price Prediction), currently yielding 2.2% after the board lifted the quarterly payout to $1.34, are taxed at 0%, 15%, or 20% long-term capital gains rates. A married couple with $96,950 in taxable income still sits in the 0% qualified bracket.
REIT distributions are different. Realty Income (NYSE:O) pays a 5.2% yield on an annualized $3.234 dividend, and most is ordinary income, taxed at marginal rates up to 37%. Bond interest gets the same ordinary treatment. Covered-call ETFs like NEOS S&P 500 High Income ETF (NASDAQ:SPYI) often classify a meaningful share of distributions as return-of-capital, which defers tax but lowers cost basis. Same $60,000 gross. Three very different after-federal numbers.
Geography rewrites the math
Three identical retirees with identical portfolios face different outcomes by zip code. Florida charges no state income tax but its cost-of-living index sits at 103.4. Pennsylvania exempts most retirement income at the state level and has a 97.6 cost index. California taxes ordinary dividend and REIT income at up to 13% and runs a 110.7 index. The California retiree can lose $4,000 to $6,000 of the $60,000 before Medicare shows up.
Medicare is not free
Medicare costs vary widely depending on income and coverage choices. At higher income tiers, Part B premiums alone can exceed $500 per month per spouse. Add a Part D drug plan, a Medigap policy, or a Medicare Advantage premium, and a couple can easily spend thousands of dollars per year on healthcare premiums before a single copay or deductible enters the picture.
The IRMAA ambush
The Income-Related Monthly Adjustment Amount uses a two-year lookback on modified adjusted gross income. A one-time property sale or a large Roth conversion in 2024 can lift 2026 Part B premiums and add $12 to $80 a month per spouse on Part D. The thresholds are abrupt. Crossing an IRMAA bracket by even a small amount can trigger a higher Medicare surcharge for the entire year, which is why retirees often monitor Roth conversions, capital gains, and income-producing investments so carefully.
Inflation finishes the job
Headline PCE ran at almost 4%, with services stuck near 3.5%. A flat $60,000 income stream loses roughly 18% of its purchasing power over 10 years at 2% inflation, 26% at 3%, and 34% at 4%. Over 20 years at 3%, that $60,000 buys what $33,000 buys today. This is why a $0.6232 quarterly dividend from NextEra Energy (NYSE:NEE), up from $0.5665 a year earlier, matters more than a static high yield. NEE has guided to roughly 10% dividend growth through 2026.
How much do you actually keep?
The answer depends on tax character, location, Medicare costs, and other sources of income. A retiree living in a low-tax state and receiving mostly qualified dividends may keep well over three-quarters of a $60,000 income stream. A retiree holding REITs and other ordinary-income investments, living in a higher-tax state, and paying IRMAA surcharges may keep considerably less. The gap between two retirees receiving the same gross income can easily reach several thousand dollars per year.
When gross income still matters
Spendable income is the working number, but gross is not useless. Estate planning, beneficiary projections, and portfolio comparisons all run on pre-tax yield. A 30-year Monte Carlo of replacement income only works if the starting figure is gross.
Three things to do this week
- Sort your income by tax character. Tag every holding as qualified dividend, ordinary, REIT distribution, bond interest, or return-of-capital. The pie chart predicts your tax bill.
- Run an IRMAA projection two years forward. An almost 5% Treasury or a Roth conversion completed this year sets your 2028 Part B premium. Model it before you execute.
- Stress-test the portfolio at 3% inflation for 20 years. If the income stream does not grow, the spendable number shrinks every year. A 2.7% NEE yield that grows 10% beats a flat 12% yield within a decade.
Plug your own portfolio value in. The output is the gross. Your job is to figure out which version of $45,000 sits underneath it.
