Bridging to Social Security
You retire at 62 but plan to wait until 70 for maximum SS. Eight critical years with no guaranteed income — here's how to navigate them.
This scenario covers
OverviewThe Bridge Challenge: 8 Years Without SS
Delaying SS from 62 to 70 increases the monthly benefit by approximately 77%. But to collect that premium, you must fund 8 years entirely from your portfolio. The math must work in both directions: enough portfolio to bridge, and enough left after the bridge to last the full retirement. For the broader decision of which age to claim at all, see Social Security 62 vs. 67 vs. 70.
| SS claiming age | Monthly benefit | Annual income | Breakeven vs. age 62 |
|---|---|---|---|
| 62 (reduced) | $1,680/mo | $20,160/yr | — (baseline) |
| 67 (FRA) | $2,400/mo | $28,800/yr | ~Age 79 |
| 70 (max) | $2,976/mo | $35,712/yr | ~Age 82 |
Tax StrategyThe Roth Conversion Window
The bridge years (62–70) are a golden opportunity for Roth conversions. With lower income (no SS yet, possibly no pension), your marginal tax rate may be unusually low — making it ideal to convert Traditional IRA money to Roth at reduced rates.
- Why convert now: At 73, RMDs from Traditional IRAs begin and could push you into a higher bracket — especially if SS is also being taxed up to 85%.
- Fill up the lower bracket: In 2026, a single filer can have up to $50,400 in taxable income in the 12% bracket — permanently, under the One Big Beautiful Bill Act (2025). Converting Traditional IRA funds up to that amount each year reduces future RMDs.
- ACA interaction: Each dollar converted counts as MAGI for ACA subsidy purposes. Plan conversions carefully to avoid crossing the subsidy cliff.
HealthcareThe ACA Subsidy Window: Age 62–65
Before Medicare at 65, healthcare is a significant expense. ACA marketplace subsidies are based on MAGI. In the bridge years, careful income management can yield massive subsidy savings.
- Below 400% FPL (<~$62,600 MAGI for single, 2025 poverty guidelines): Subsidized premiums, often $200–$500/month.
- Above 400% FPL: Full premium, potentially $1,000–$1,500/month for a 63-year-old.
- Roth conversion vs. subsidy trade-off: Each $10,000 of conversion narrows your subsidy margin. The optimal strategy balances long-term tax savings vs. near-term premium savings.
ExecutionOptimal Withdrawal Mix During Bridge Years
With multiple accounts (taxable brokerage, Traditional IRA, Roth IRA), the order of withdrawals during the bridge years significantly impacts lifetime taxes and ACA subsidies.
| Year | Primary withdrawal source | Why |
|---|---|---|
| 62–65 (pre-Medicare) | Taxable brokerage (capital gains) | Long-term cap gains taxed at 0% in lower brackets; no impact on ACA until gains realized |
| 62–70 (Roth conversion) | Traditional IRA → Roth (partial) | Fill 12% bracket, reduce future RMDs |
| 65–70 (post-Medicare) | Mix of Roth + small Traditional | Minimize IRMAA exposure; Roth withdrawals have no MAGI impact |
Verdict: Is the SS Bridge Worth It?
For most retirees in good health who can afford the bridge, waiting to 70 is the highest-value financial decision available. The break-even is typically age 82 — well within average life expectancy. Combined with strategic Roth conversions during the bridge, the plan can save $50,000–$100,000 in lifetime taxes. The key requirement: enough portfolio to fund 8 years without touching SS prematurely.
