Married vs. Unmarried: Does It Make Sense to Marry for Social Security?
In our recent posts, we looked at Social Security claiming strategies for unmarried couplesandfor married couples. The two playbooks look very different. Married couples coordinate spousal and survivor benefits as a team. Unmarried partners each stand on their own record.
That raises a natural question: does it make sense to get married for Social Security? For some couples, the answer is yes, and the difference can be worth hundreds of thousands of dollars over a lifetime. For others, marriage adds little or even costs them a benefit they already have.
Married vs. Unmarried: Side by Side
| Married couples | Unmarried couples | |
|---|---|---|
| Your own retirement benefit | Yes | Yes |
| Spousal benefit (up to 50% of partner's FRA benefit) | Yes, after one year of marriage | No |
| Survivor benefit (up to 100% of partner's benefit) | Yes, after nine months of marriage | No |
| $255 lump-sum death payment | Yes | No |
| Benefits from a prior marriage (10+ years) | Lost if you remarry (divorced-spouse benefits), or if you remarry before 60 (survivor benefits) | Kept |
| Key claiming strategy | Higher earner delays to protect the survivor; lower earner times claim around cash flow | Each partner maximizes their own record |
| Protecting the survivor | Built into Social Security | Must be built with life insurance, beneficiary designations, and estate documents |
| Tax on benefits | Joint thresholds: $32,000 / $44,000 | Each partner's own thresholds: $25,000 / $34,000 |
The biggest difference is the survivor benefit. A married survivor keeps the larger of the two checks. An unmarried survivor keeps only their own.
When Marriage Can Pay Off
Marriage tends to add the most Social Security value when:
One partner earned much more than the other. The lower earner can collect a spousal benefit worth up to half of the higher earner's FRA benefit, and later step up to the higher earner's full check as a survivor.
One partner has little or no work history. Someone without 40 credits may not qualify for a benefit of their own. Marriage can give them access to spousal and survivor benefits.
The higher earner is older or in poorer health. The younger or healthier partner may collect a survivor benefit for many years.
The higher earner plans to delay to 70. Delaying grows the check by about 8% a year past FRA. In a marriage, the survivor inherits that larger check. Unmarried, that extra value ends when the higher earner dies.
Savings are limited. Without enough assets or life insurance to replace a lost check, the survivor benefit may be the most affordable protection available.
When Marriage May Not Help, or Could Cost You
Marriage adds little Social Security value, or can even reduce it, when:
You both earned about the same. Each of you will likely collect more on your own record than a spousal benefit would pay. The survivor benefit still helps, but the gain is smaller.
You collect benefits from a prior marriage. A divorced-spouse benefit ends if you remarry. A survivor benefit from a late spouse ends if you remarry before 60. If that benefit is larger than what a new marriage would provide, staying unmarried may protect it.
Your benefits are taxed more as a couple. Single filers each get their own thresholds before benefits become taxable. Married couples share lower combined thresholds, so the same income can lead to more tax on benefits.
You can already protect the survivor another way. Couples with substantial assets, life insurance, and solid estate planning may be able to replace a lost check without the survivor benefit.
Social Security is only one piece. Marriage also affects income taxes, estate planning, health coverage, and legal rights, so weigh the full picture.
Illustration: One Couple, Two Outcomes
Let's revisit the couple from our married-couples post. Both partners are 65. Partner A, the higher earner, has a $3,000 FRA benefit and waits until 70 to claim $3,720 a month. Partner B has a $1,200 FRA benefit and claims at 67. Partner A dies at 80, and Partner B lives to 92.
Here's what Partner B receives each month, married or not:
| Partner B's age | If married | If unmarried |
|---|---|---|
| 67 to 70 | $1,200 (own benefit) | $1,200 (own benefit) |
| 70 to 80 | $1,500 (own benefit + $300 spousal top-up) | $1,200 |
| 80 to 92 | $3,720 (survivor benefit) | $1,200 |
| Total, ages 67 to 92 | About $759,000 | About $360,000 |
In this example, marriage is worth nearly $400,000 to Partner B, before cost-of-living adjustments. Most of that comes from the survivor benefit. After Partner A's death, Partner B's monthly income is $3,720 if married, compared with $1,200 if not.
This is a hypothetical example for illustration only. Your results depend on your own benefits, ages, and life expectancy.
If You Decide to Marry: Timing Matters
Spousal benefits generally require one year of marriage. Plan the wedding date around when the lower earner hopes to start a spousal benefit.
Survivor benefits generally require nine months of marriage. Exceptions apply, such as an accidental death.
Check your prior-marriage benefits first. Remarrying at 60 or later keeps a survivor benefit from a late spouse. A divorced-spouse benefit ends with any remarriage.
Common-law marriage depends on your state. Florida doesn't allow new common-law marriages, so most Florida couples need a legal marriage for these benefits.
Questions to ask before deciding:
How far apart are our benefits at full retirement age?
Who is likely to live longer, and by how much?
Is either of us receiving benefits from a prior marriage?
How would marriage change our income taxes and estate plan?
Could life insurance or savings protect the survivor just as well?
The Bottom Line
Marriage can make a big difference in Social Security, especially for couples with uneven earnings, where the survivor benefit alone can be worth hundreds of thousands of dollars. For couples with similar earnings, or those already collecting benefits from a prior marriage, the math may point the other way.
Either way, Social Security shouldn't be the only reason to marry or stay single. At Merited Wealth, we help couples bring Financial Clarity and Action to decisions like these.
