To calculate taxable Social Security, determine your "combined income" (AGI + nontaxable interest + 1/2 of your SS benefits) and compare it to IRS thresholds: if below $25k (single) or $32k (joint), none is taxed; if above, 50% or 85% of benefits may be taxed, using IRS Publication 915 or worksheets in Form 1040 instructions to find the exact taxable portion (0%, 50%, or 85%).
You know if your Social Security is taxable by calculating your "combined income": add your Adjusted Gross Income (AGI), any nontaxable interest, and half your Social Security benefits; if this total exceeds the IRS thresholds ($25k single, $32k married filing jointly), some or all of your benefits are taxed, with up to 85% potentially being taxable, depending on the income level. The SSA-1099 form, received annually, shows your total benefits for the year, which you use for this calculation.

The amount you pay in federal income tax on your Social Security benefits is based on your “combined income,” as the Social Security Administration (SSA) terms it. That's your adjusted gross income, plus any nontaxable interest you earned (along with certain other items), plus half your Social Security income.
Social Security benefits are calculated using your highest 35 years of inflation-adjusted earnings, averaged to get your Average Indexed Monthly Earnings (AIME), then applying a progressive formula (using bend points) to find your Primary Insurance Amount (PIA), which is your monthly benefit at full retirement age, adjusted for early or delayed claiming and Cost-of-Living Adjustments (COLAs).
Yes, Social Security benefits can be taxable at the federal level (and sometimes state level) if your "combined income" (half your benefits + other income) exceeds certain thresholds ($25,000 single / $32,000 married filing jointly), with up to 50% or 85% of benefits becoming taxable depending on how high your income goes.

You can generally earn up to around $25,000 (single) or $32,000 (jointly) in other income, plus your Social Security, before any benefits become taxable, but if Social Security is your only income, you can receive up to $25,000 in benefits without filing taxes (single) or $32,000 (joint). The key is your combined income: half your benefits plus other income (wages, pensions, investments). If this combined income is below the threshold, no taxes; above it, up to 50% or 85% of benefits can be taxed, depending on how much over the threshold you are.
Social Security income becomes taxable when your "combined income" (half your benefits + other income) exceeds certain thresholds: $25,000 for individuals or $32,000 for joint filers; above these, up to 50% or 85% of your benefits may be taxed, depending on how much higher your income is, with higher thresholds of $34,000 (single) and $44,000 (joint) triggering the 85% taxation level.

Yes, many Social Security recipients have to file taxes if their total income (including half their benefits, pensions, and other earnings) exceeds certain thresholds, but if Social Security is your only income, you generally don't need to file unless your benefits are very high (e.g., over $25,000 for singles). The key is your "combined income" (AGI + tax-exempt interest + half your benefits); if it's over $25,000 (single) or $32,000 (married filing jointly), a portion of your benefits becomes taxable, up to 85%.
The "Social Security 50% Rule" refers to the maximum spousal benefit, where a spouse can receive up to 50% of the primary earner's full Social Security retirement benefit, but only if they wait until their own Full Retirement Age (FRA) (FRA) to claim, otherwise it's reduced, with a potential future reduction in the percentage to 33% by 2042 under current proposals. This spousal benefit is paid if it's higher than the spouse's own earned benefit, and claiming early for the primary earner doesn't reduce the potential 50% spousal benefit amount if the spouse waits until their FRA.
