How a Retired Couple Can Realize ~$116,000 of Capital Gains at $0 Federal Tax in 2026

The three deductions a senior stacks in 2026

For a married couple, both age 65 or older, taking the standard deduction:

The senior bonus is the new one — created by the One Big Beautiful Bill Act for tax years 2025 through 2028. It's worth up to $6,000 per person 65+ ($12,000 for a couple), whether you itemize or not. It phases out above $150,000 MAGI for couples ($75,000 single) and disappears by $250,000 ($175,000 single) — so it rewards keeping income modest, which is the whole point below.

Now add the 0% long-term capital gains bracket

Long-term capital gains are taxed at 0% federally as long as your taxable income stays under roughly $99,000 (MFJ, 2026). Gains stack on top of your ordinary income — so the less ordinary income you have, the more gain fits inside the 0% band.

Worked example — a retired couple, both 65+, in 2026:

• Ordinary income (pension, interest): $30,000
• Deductions wipe it out: $30,000 − $47,500 = $0 taxable ordinary income (with $17,500 of deduction to spare)
• They then realize long-term capital gains. To stay in the 0% bracket, taxable income must stay ≤ ~$99,000.
• Gain they can realize at 0%: ~$99,000 + $47,500 − $30,000 ≈ $116,000

That couple realizes about $116,000 of long-term capital gains and owes $0 in federal capital-gains tax. A single filer 65+ (standard $16,100 + $2,050 + $6,000 = $24,150 in deductions, 0% bracket ~$49,500) can do roughly $73,000 the same way.

The catch — and why a structured installment sale is the answer

Here's the trap: if that couple sells a $2M rental outright, the entire gain lands in one year. Taxable income rockets past $99,000, so the 0% bracket is blown — and MAGI blows past $150,000, so the senior bonus deduction phases out too. They get crushed on both ends.

A structured installment sale (IRC §453) fixes it. Instead of one giant gain year, the sale pays out over a schedule you choose, and the gain is recognized proportionally each year. Keep the annual recognized gain inside the 0% band, and:

• Each year's gain can be taxed at 0% federal (if income stays under the threshold),
• MAGI stays low enough to keep the senior bonus deduction every year,
• and the balance keeps earning a guaranteed, insurer-backed yield while it waits.

For a senior sitting on a highly appreciated property or business, that turns a one-time tax bomb into a multi-year, potentially zero-federal-tax harvest. California still taxes the gain as ordinary income (there is no separate CA capital-gains rate), so this is a federal strategy — but stretching the gain lowers the California bill too by keeping each year in lower brackets.

Who this actually fits

• Retirees 65+ with modest ordinary income and a large appreciated asset (rental, land, a business, a concentrated stock position).
• MAGI that can be kept under $150,000 MFJ / $75,000 single per year — which the installment schedule is designed to do.
• Sellers who don't need the full lump sum on closing day.

Not a fit if you need all the cash at once, or your other income already fills the brackets every year regardless (see the high-earner analysis for that case — the win there is deferral, not the 0% bracket).

Frequently asked

Is the senior bonus deduction real, and how long does it last? Yes — it's in the One Big Beautiful Bill Act, worth up to $6,000 per person 65+, available for tax years 2025–2028, and it applies whether you itemize or take the standard deduction. It phases out above $150,000 MAGI (MFJ) / $75,000 (single).

Can a senior really pay $0 federal capital gains? On gains that fit inside the 0% long-term bracket, yes — that bracket has existed for years. The OBBB senior deduction simply enlarges the room by lowering taxable income further. The hard part on a large sale is keeping each year's income low enough — which is exactly what a structured installment sale does.

Does this eliminate California tax too? No. California has no separate capital-gains rate — it taxes the gain as ordinary income, up to 13.3%. Spreading the gain lowers the California bill by keeping each year in lower brackets, but it doesn't zero it out the way the federal 0% bracket can.
