SPIA vs MYGA for Bridging to Social Security: Which One Actually Works

TL;DR: Most people default to a MYGA when they want to bridge income to a later Social Security claim, because MYGAs feel familiar — they look like a CD. For actual monthly bridge income, a period-certain SPIA usually beats a MYGA on three fronts: no reinvestment or laddering, income comes out as income (not a lump sum you then convert), and non-qualified SPIAs get an exclusion ratio that cuts taxable income by 80-90%. MYGA wins when your delay decision is tentative and you want the optionality of a lump sum at the end.

Why people default to MYGA (and when it's the wrong default)

MYGAs feel safe because they map onto how people already think about savings. You deposit a lump sum, it grows at a fixed rate, you get it back at the end. It's a CD wearing an insurance label. That mental model is why 70-80% of the "how do I fund my SS bridge" conversations I have start with the client saying "I was thinking a 5-year MYGA."

Here's the friction: a MYGA doesn't actually pay you monthly income. It grows silently for the term and then hands you a lump sum. If your goal is to fund the years between 62 and 67 (or 65 and 70) with steady monthly income, you now have to convert that lump sum yourself. You either take penalty-free withdrawals up to the 10%/year corridor (usually not enough) or you eat the surrender charge to pull more.

The SPIA structure eliminates the middle step. Premium in, monthly checks out, no reinvestment, no laddering, no lump-sum-conversion problem. When the actual use case is "5 years of $2,800/month," that's what a SPIA delivers by design.

The $200K head-to-head at 5 years

Compare $200K premium into a 5-year MYGA at 5.5% vs a 5-year period-certain SPIA at current market rates.

Attribute	MYGA (5yr @ 5.5%)	SPIA (5yr period-certain)
Monthly income during bridge	$0 (accumulates)	~$3,780
Total received / value at end	~$261,600 lump sum	~$226,800 across 60 payments
Implied return	5.5% guaranteed	~5.15% guaranteed
Taxable income during bridge (non-qualified)	Deferred until withdrawal	~$450/mo (only interest portion)
Reinvestment / laddering risk	All at year 5	None — already streaming
Sequence risk on bridge cash flow	Full lump sum sits until year 5	None — payments locked
Death during term (beneficiary receives)	Current account value	Remaining scheduled payments

MYGA looks like it "returns more" because the lump-sum number is bigger. That's an illusion of accounting. The SPIA's total is smaller because it starts paying immediately — every dollar paid out in year one isn't sitting in the contract earning interest.

If you replicated the SPIA cash flow from the MYGA (pulling $3,780/month starting year one), you'd hit the 10% penalty-free corridor limit and start eating surrender charges by mid-year one. That's the mechanical friction the SPIA solves.

The tax angle changes the answer

Here's where non-qualified SPIA funding creates a real gap. On the MYGA, the interest is fully taxable when you eventually withdraw — either as ordinary income each year if you pull it, or as a lump sum tax hit at year 5.

On the SPIA, non-qualified funding means each monthly payment is split by an exclusion ratio: roughly 85-90% is treated as return of principal (not taxable), and only 10-15% is taxable interest. Across a 5-year SPIA, that's about $27K of total taxable income spread over 60 months — roughly $5,400/year.

Compare that to a MYGA that grew tax-deferred and gets fully liquidated at year 5. That's roughly $61,600 of taxable interest all landing in a single tax year. For someone trying to stay under IRMAA thresholds or avoid a 22% federal bracket, that's a real problem — the tax cliff at MYGA maturity can be worse than the interest earned.

MYGAs solve this partially by allowing 1035 exchanges into another annuity contract (deferring the tax further). But that just kicks the can. Eventually the taxable interest hits, and it hits as a lump sum.

The "what if you die at 66" question

This is the pushback I get on SPIA every time: "what if I die at 66 and don't collect the full amount?"

For a period-certain SPIA, this question is a non-issue. The contract pays a scheduled monthly amount for a fixed number of years. If you die at year 3 of a 5-year SPIA, your named beneficiary receives the remaining 24 payments. Nothing is forfeited.

The forfeiture concern is only real for life-only SPIAs (which pay until death, whenever that comes). Life-only SPIAs are a different product and rarely the right tool for bridge income — they're for retirees trying to maximize monthly payout on a lifetime basis.

For a bridge, always use period-certain. There's no death-forfeiture downside relative to a MYGA. Both pass to beneficiaries.

Break-even scenarios and edge cases

Three scenarios where MYGA wins over SPIA for the same client:

The delay decision might reverse. Client isn't fully committed to delaying SS. Maybe they'll take it at 65, maybe 67, maybe 70. Health event or lifestyle change could change the answer. MYGA leaves flexibility — you can just take the lump sum at end of term and redeploy.
Qualified money only. If the funding source is a traditional IRA, the SPIA's exclusion-ratio advantage goes away (everything's taxable ordinary income either way). The MYGA's simplicity in an IRA context often wins.
Small bridge amount. If you only need to bridge $500/month, the mechanical complexity of a SPIA is overkill. Just do MYGA and pull the interest annually.

And three scenarios where SPIA clearly wins:

Non-qualified funding source. Taxable brokerage, matured CD, or matured MYGA rolling into the bridge. Exclusion ratio benefit is substantial.
Firm delay decision. Client is definitely delaying to 70 and needs exactly 5-8 years of steady income. SPIA maps to the use case directly.
IRMAA sensitivity. Client is close to the Medicare IRMAA threshold. SPIA exclusion ratio keeps taxable income lower and can save $1,500-$5,000/year in IRMAA surcharges.

How I structure this for clients

The workflow when a client is evaluating SPIA vs MYGA for bridge income:

Confirm the delay decision. Is this firm or tentative? Firm = SPIA gets the lead consideration. Tentative = MYGA gets it.
Identify the funding source. Qualified or non-qualified? Non-qualified unlocks the SPIA exclusion ratio benefit.
Model the after-tax cash flow. Quote both products across the same term (usually 5-7 years). Compare after-tax net monthly income, factoring in IRMAA thresholds.
Stress-test the sequence. What happens if the client's spending needs change mid-bridge? Which product handles the change more gracefully?
Write the recommendation. One-page memo showing side-by-side, plus the specific carrier and product I'd use for the client's exact situation.

For most non-qualified, delay-committed bridge cases, the SPIA wins by 10-25% on after-tax net over the term. But it's case by case — the modeling matters.

Frequently Asked Questions

What's the difference between a SPIA and a MYGA?

A MYGA is a fixed-rate deferred annuity — it grows at a locked rate for a fixed term and you take the lump sum at the end. A SPIA is a payout annuity — you hand the carrier a premium and they pay you monthly income for a set number of years or for life. For bridge income, they're solving the same problem in different ways.

Which one is safer?

Both are backed by the issuing insurance carrier's claims-paying ability and, secondarily, by state guaranty association limits. Neither is FDIC-insured. Safety comes from the carrier's financial rating, not the product type. Both SPIA and MYGA from an A-rated carrier are functionally equivalent on default risk.

Why does the SPIA have lower tax drag if funded with non-qualified money?

Non-qualified SPIA payments have an exclusion ratio — part of every payment is treated as return of principal and isn't taxed. Only the interest portion is taxable. On a 5-year SPIA, roughly 85 to 90 percent of each payment can be excluded, dramatically reducing annual taxable income compared to a MYGA where you may face full ordinary income on the interest at maturity.

What if I die during the SPIA bridge period?

With a period-certain SPIA, remaining payments go to your named beneficiary. Same with a MYGA — the death benefit is the account value at time of death, which passes to the beneficiary. Both avoid forfeiture. The difference is that the SPIA beneficiary continues receiving the same monthly payments; the MYGA beneficiary gets the current account value.

Which is better if I'm not sure I'll actually delay Social Security?

MYGA. If your decision to delay might reverse (income needs change, health event, etc.) the MYGA leaves you with a lump sum you can redeploy however you want. The SPIA commits you to the payment stream. When the delay decision is firm, SPIA wins on income mechanics; when it's tentative, MYGA wins on flexibility.

Can I use a MYGA and just take withdrawals during the bridge years?

Most MYGAs allow 10 percent free withdrawals per year, but withdrawals above that trigger surrender charges. Trying to use a MYGA as a payout vehicle usually violates the surrender schedule and costs more than the interest earned. That's what makes the SPIA the cleaner bridge tool.
