Wait a minute - has anyone mentioned the impact on taxes here? When my wife started collecting her retirement on top of my SSDI, it pushed our combined income into a higher tax bracket and suddenly 85% of my SSDI became taxable! The extra benefit amount wasn't worth the tax hit. Make sure to consider the tax implications before you get excited about any potential increase!

Based on the numbers you shared, let's do a quick calculation: If your husband's benefit at his full retirement age (before any delayed retirement credits) is around $2,800, then 50% of that would be $1,400. Since your current SSDI is $1,650, which is higher than the $1,400 spousal benefit you might be eligible for, you likely won't receive any additional amount through dual entitlement. However, these are just estimates. Your husband's PIA (Primary Insurance Amount) might be different from his actual benefit if he's delaying past full retirement age. I'd still recommend applying for the spousal benefit once he files, just to make sure you don't miss out on any potential increase.

have you checked whether you can get benefits based on YOUR work record? my friend thought her ex would give her more but turned out her own SS was actually better!!!

I wish they would make these rules simpler to understand. It's like they WANT us to mess up our retirement planning! When my mom retired, she had no idea she could have gotten more by waiting until her FRA. Now she's stuck with a permanently reduced benefit. The whole system feels rigged sometimes.

Has your SIL checked if she'd be subject to WEP or GPO??? My friend's wife thought she'd get spousal benefits too but got hit with the windfall elimination provision because she had a government pension!!! If your SIL worked for state govt or federal job without paying into SS, that could change EVERYTHING!!!!

Just wanted to share that I was in this exact situation - high earner husband, also good income myself. I got ZERO spousal benefits. My own benefit at FRA was about $2,800 and half of his PIA was only $1,900 so no excess for me. Probably same for your sister-in-law if she has a good earnings record.

One thing to keep in mind - if your ex hasn't claimed yet but does so in the future, they might get a higher benefit from their own record depending on their earnings history. The SSA will pay whichever is higher: their own retirement benefit or the spousal benefit (which maxes out at 50% of your PIA). So don't assume they'll automatically claim on your record even if eligible.

Does your ex know that you're delaying until 70? Because if they're collecting on your record while you're delaying, they're only getting the benefit calculated on your PIA at your full retirement age, not the increased amount you'll get at 70. Just FYI.

my neighbor works for our state pension system and she said they've been swamped with questions about this! apparently the state retirement systems don't have any more info than we do right now lol

One important update: Based on the information shared, I ran a quick calculation using what we know about the new proportional formula. With 18 years of substantial earnings under Social Security out of a 48-year career, approximately 37.5% of your career was in covered employment. The new formula will likely result in you keeping about 37.5% of the difference between your WEP-reduced benefit ($675) and your non-WEP benefit ($1,850). So: $675 + (0.375 × ($1,850 - $675)) = approximately $1,116 per month. This is just an estimate based on the general formula, but it gives you a better idea of what to expect. The actual calculation will be more complex and depend on your specific earnings history.
