The honest answer most pastors avoid: it depends on whether you tithed on those wages while you were working. The governing principle is no double-tithing on the same dollar.
How Social Security is funded (this matters)
Your Social Security check has two sources:
- Your contributions — 6.2% of every paycheck during your working years, deducted as FICA tax. You already received this as income and (if you tithed) already tithed on it.
- Your employer's matching contributions — another 6.2%, paid by your employer on your behalf. You never saw this as income, never tithed on it.
Plus the system pools and redistributes, so the actual check you receive isn't a clean return of your specific contributions. But the principle holds: roughly half of every Social Security dollar was paid by your employer and never tithed.
Three honest positions
- Position 1: Tithe the full check. Safest, simplest, most generous. The argument: don't try to be clever with God's math; the check is current increase, tithe 10% of it.
- Position 2: Tithe ~50%, representing the employer portion. Mathematically defensible if you faithfully tithed on every paycheck during your working years. The argument: don't double-tithe on dollars you've already tithed.
- Position 3: Tithe the full check if you didn't tithe consistently during your working years. If you only started tithing late in life, treat Social Security as untithed increase and tithe the full amount.
What about 401(k) and IRA distributions?
Same principle, cleaner application:
- Traditional 401(k)/IRA — pre-tax contributions, never tithed during working years (you tithed on gross, but contributions went in pre-tax, so the matching/growth wasn't tithed). Tithe the full distribution.
- Roth 401(k)/IRA — post-tax contributions, already tithed. Tithe only the growth portion if you can separate it, otherwise tithe nothing on principal and tithe full on growth.
- Employer match in any account — never tithed during your career. Tithe distributions of the match portion.
Our recommendation
If you can afford it, tithe the full check. The accounting gymnastics of separating out tithed-vs-untithed portions are real, but the spiritual posture of generous, simple firstfruits-giving in retirement matters more than optimizing the math.
If you genuinely can't afford to tithe the full check on a fixed income, the 50% (employer-portion) position is defensible. What's not defensible: stopping tithing entirely because "I'm retired now." Retirement is not a sabbatical from stewardship.
