When applying for Social Security retirement benefits, do you specify month and day or just month?

You only need to specify the month, not the day. Social Security retirement benefits always begin on the first day of whatever month you select. The application just asks for the month and year. Keep in mind that your first payment will come the month AFTER your benefits start (so if you select September 2025, your first payment would arrive in October).

just applied last month and yes you only put the month not the day. they actually dont even ask for a day on the form

My brother applied last year and they messed up his start date somehow. He wanted January but they started him in February! He had to call like 20 times to get it fixed. Make sure you print out confirmation pages!!

When I talked to SSA about this recently, they explained that retirement benefits are always effective the first day of a month, regardless of when in the month you were born. The only exception is if you're born on the 1st of the month - then you can actually get benefits for the month before your birthday month. So your application will only ask for month/year, not a specific day.

Anyone else spending HOURS trying to get through to SSA to ask simple questions like this? I needed to ask about my application start date too and spent 3 days trying to reach someone! Finally found this service called Claimyr (claimyr.com) that got me connected to an agent in about 20 minutes. They have a video showing how it works: https://youtu.be/Z-BRbJw3puU - way better than the constant busy signals and disconnects I was getting before.

Does anyone know how this works if I change my mind about the start month after submitting my application? Let's say I apply now specifying September 2025, but later decide I want to start in October instead. Is that difficult to change?

One more important thing about the month selection: if you're filing BEFORE your Full Retirement Age, be extremely careful about which month you select. The earnings test could significantly reduce your benefits if you're still working. You need to calculate your projected earnings carefully against the annual limit ($22,750 in 2025 for those below FRA the entire year). This gets very complicated very quickly if you're still working!

Just want to add that if you're planning to apply for September 2025 benefits, you can actually submit your application up to 4 months in advance (so as early as May 2025). This gives SSA plenty of time to process everything and ensures your benefits start on time. I learned this the hard way when I applied too close to my desired start date and had to wait an extra month. The online application at ssa.gov walks you through everything step by step and clearly shows you're only selecting month/year, not specific days.

As someone who works as a benefits counselor, I can confirm everything that's been shared here is accurate! You only select the month, not a specific day. The SSA application form doesn't even have a field for the day because all retirement benefits automatically begin on the 1st of the selected month. One additional tip I'd offer: when you're ready to apply, consider doing it online at ssa.gov rather than in person or by phone. The online application saves your progress automatically, so you can take your time and come back to it if needed. It also gives you immediate confirmation of what you've submitted. Just remember that applying 3-4 months before your desired start date gives you the best chance of having everything processed smoothly and on time.
