Bone up on strategies that will get you the maximum Social Security benefits you've earned. Getty Images By Rachel L. Sheedy, Editor February 23, 2018From Kiplinger's Retirement Report A big reason experts advise waiting until at least full retirement age to claim Social Security: You get to skip the benefits earnings test, which hits early claimers who are still working. But there are actually two earnings tests–and the second test can help early retirees leaving work midyear avoid the trap.SEE ALSO: Quiz: Do You Know the Best Social Security Claiming Strategies? The Social Security Administration always applies the annual earnings test first. Based on that test, the agency temporarily withholds $1 of a worker's benefits for every $2 earned over $17,040 in 2018. In a year the worker hits full retirement age, the test is more generous–the worker forfeits $1 in benefits for every $3 in 2018 earnings above $45,360. In the month a worker hits full retirement age–poof!–the earnings test goes away. The worker can earn whatever he or she likes, and the monthly benefit amount will be adjusted upward to take into account all benefits forfeited in the past (more on recouping lost benefits below). But if you're tripped up by the annual test, you still have a shot at your full benefit. The agency will apply a monthly earnings test and set your payments according to whichever test is better for you. "It helps people who retire in the middle of the year not to be penalized," says Jim Blair, a former Social Security district manager and a partner at Premier Social Security Consulting, in Sharonville, Ohio. The monthly test can be used for only one year, usually the first year of retirement. And it comes into play generally for midyear retirees who have already earned more than the annual limit. Those who pass the monthly earnings test can receive 100% of their benefits for any whole month the agency considers them retired, regardless of total annual earnings. Advertisement Taking the Monthly Social Security Earnings Test Here's how the monthly earnings test works: If you are under full retirement age for all of 2018, you are considered retired in any month you earn $1,420 or less. If you reach full retirement age in 2018, you are considered retired in any month you earn $3,780 or less. SEE ALSO: 13 States That Tax Social Security Benefits Say a beneficiary turns 62 in June. He wants to start benefits in July after working through the end of June and making $80,000 in 2018. On an annual basis, he'd get no benefit. But in July through December, if he earns $1,420 or less each month, the monthly earnings test would open the door to full benefits. "You have to be careful if you go up to $1,421–then the agency would add the $80,000," Blair says. In that case, you would lose a check for that month, but not for other months when benefits are below the monthly threshold. "A sneaky five-Friday payday month might end up passing the monthly earnings amount," he says. When retiring in the year you reach full retirement age, the earnings test only applies in the months prior to the month of your birthday. The higher threshold of $3,780 would apply if the monthly test is used in 2018. The earnings tests count only earned income from a job or self-employment; investment income, for example, and retirement-plan payouts are ignored.

The agency will want the money back–and will withhold benefit checks until the overpayment is cleared. Recouping Lost Benefits The burning question when a person loses Social Security benefits to the earnings test: When do I get my money back? Unfortunately, you won’t get all your temporarily forfeited benefits back in a lump sum at full retirement age. Instead, your monthly benefit amount is adjusted upward in the month you hit full retirement age to account for forfeited benefits. The disappearing benefits essentially reduce the amount of time you were considered to have claimed benefits early. SEE ALSO: Claim Social Security Early or Wait? Advice from the Pros Say you took benefits at age 62 instead of waiting to your full retirement age of 66, giving your benefits a haircut of 25%. If you forfeited 12 months’ worth of benefits to the earnings test, at your full retirement age, you’ll be treated as if you claimed benefits three years early, instead of four. Your lifetime benefits reduction will get slashed from 25% to about 20%. That puts more money in your check every month, and if you live long enough, you’ll recoup all the benefits the earnings test temporarily took away.
