Social Security if you were born in 1956: the year you turn 70
This is the deadline year: the 70th birthday month is the last one that adds anything to the check.
Checked by Radif Partners · Editorial policy · How we calculate
People born in 1956 (from January 2, 1956 to January 1, 1957) turn 70 during 2026, which makes this the final year in which waiting raises a Social Security retirement benefit. Their full retirement age, 66 and 4 months, arrived in 2022; each month of delay since then has added two thirds of 1% to the primary insurance amount, so a claim starting in the month of the 70th birthday pays 129.33% of the PIA, the result of 44 months of credit. The PIA itself was set by the 2018 formula (bend points $895 and $5,397) on earnings indexed to 2016 wages, then raised by every COLA from December 2018 through the 2.8% increase of December 2025. For a career at $60,000 in today's pay, that means $2,163 a month at full retirement age against $2,798 from 70. Any month after 70 adds nothing.
Delayed credits until the month you turn 70
Monthly benefit starting at 70
$2,845
| Full retirement age | 66 and 4 months |
| Months of credits by 70 | 44 (29.3%) |
| Starting at 69 instead | $2,669 |
| Year you turn 70 | 2026 |
No credit is earned after the month you reach 70. Before COLAs.
The last stretch of delayed credits
Delayed retirement credits exist only between full retirement age and 70 (20 CFR 404.313). For people born in 1956 that window opened in 2022 and closes in 2026, in the month of the 70th birthday. Late in the window each month adds the same two thirds of 1% as early on, which is why the table keeps climbing in a straight line right up to the end.
| Benefit starts at | Months of credit | Share of PIA | Example (PIA $2,163.90) |
|---|---|---|---|
| 66 and 4 months (2022) | 0 | 100.00% | $2,163 |
| 67 (2023) | 8 | 105.33% | $2,279 |
| 68 (2024) | 20 | 113.33% | $2,452 |
| 69 (2025) | 32 | 121.33% | $2,625 |
| 69 and 6 months (2025-2026) | 38 | 125.33% | $2,712 |
| 69 and 9 months (2026) | 41 | 127.33% | $2,755 |
| 70 (2026) | 44 | 129.33% | $2,798 |
The step from 69 to 70 is worth $173 a month in this example, for life and before future COLAs. Whether a year of waiting pays off is a question of how long benefits are collected; the claiming-age tool computes the break-even age.
Filing on time, or a little late
Being a few weeks late is not costly. The retroactivity rule allows benefits for up to 6 months before the month you apply, provided the benefit is not reduced for age, which is never the case at 70. An application filed in the autumn can therefore still begin in the birthday month. Waiting longer than 6 months after 70 does lose money, because the oldest months fall outside the window.
One timing detail matters for the first check. Normally credits earned during a year are added only the next January, but the year of the 70th birthday is handled differently, and the full 29.33% increase is applied from the start (SSA delayed retirement page).
The 2018 formula behind every 1956 benefit
All 1956 births share the 2018 bend points, $895 and $5,397, a year in which the first bend point rose by only $10 because the national average wage index grew only 1.1% in 2016. Their AIME was indexed to the 2016 national average wage, 48,642.15, and the earnings of 2016 and later count at face value. Since 2018 the PIA has grown by 32.4% through COLAs, from $1,634.30 to $2,163.90 in this example.
Still at work at 70? Earnings no longer trigger any withholding past full retirement age, and a strong year can replace a weak one in the 35 used for the average, as explained on working after full retirement age.
