GRAND RAPIDS, Mich. (WOTV) – What’s the best age to start collecting social security? You can start collecting as early as 62 or as late as age 70, but it definitely pays to wait. If you can hold off collecting, you’ll increase your benefits by 8% every year. over your lifetime, this could add up to thousands of dollars. but be sure to collect once you reach 70. After that there are no additional benefits accrued. AARP has tons of resources about social security on their website.
