Social Security Questions? Ask a Social Security Expert
Hi. My name is ***** ***** I will be happy to help you.
You cannot file and suspend your benefits after April 30, 2016 any more. But I think that's not what you want to do. If you want to apply for lower spousal benefits and let your own grow until 70, you will need to file a "restricted application", no file and suspend. File and suspend means no benefits at all. If your own benefits are lower than your spousal benefits (50% of your husband's benefits), you can apply for spousal benefits online or by calling social security directly.
If you want to apply for restricted application I would suggest to call instead of applying online, to make sure that you don't apply for your own by accident.
Here's how you can apply: https://www.ssa.gov/forms/apply-for-benefits.html
