You paid into Social Security for decades.
That does not mean anyone explained how it works.
Start with the basics. Claiming age, taxes, spouses, survivors and working while collecting all matter, but they make more sense one piece at a time.
Social Security has a funding problem, but that does not mean your check goes to zero. Current projections show enough funding for full scheduled benefits into the 2030s. If nothing changed after the trust funds ran short, incoming payroll taxes would still cover most scheduled benefits.
A lot of people assume Social Security is tax-free. Depending on your other income, part of it can be taxable. Part-time wages, traditional IRA withdrawals, interest, dividends and other income may all matter.
It means up to 85% of the benefit can be included in taxable income. Your normal income-tax rates apply to that taxable income.
It does not mean the government takes 85% of your Social Security check.
Your own work history is not always the only benefit that matters. If your own retirement benefit is lower, you may qualify for additional spousal benefits based on your spouse's work record.
The "your spouse gets half" shortcut leaves out important rules.
The maximum regular spousal benefit is based on up to 50% of the worker's full-retirement-age amount, not necessarily half of the check the worker actually receives. The spouse's own benefit and claiming age also matter.
Waiting longer does not increase the ordinary spousal benefit above its normal maximum.
But delaying the higher earner's own benefit can increase the survivor benefit available after that person dies.
Before full retirement age, earning above the annual work limit can cause Social Security to temporarily withhold benefits.
For people born in 1960 or later, full retirement age is 67.
When you reach full retirement age, Social Security recalculates your monthly benefit and gives you credit for months when benefits were withheld.
It is not a lump-sum refund. Your monthly check going forward is adjusted.
For people born in 1960 or later, full retirement age is 67.
You can claim as early as 62, but the worker benefit can be about 30% lower.
Wait until 70 and the worker benefit is roughly 24% higher than the full-retirement-age amount.
Waiting past 70 does not make it grow further.
