Could your client use the IRA 'bridge' strategy? Here are the numbers

For some clients, taking distributions from their traditional individual retirement accounts before retirement may be a bridge too far. For others, the strategy could lead them from pre-retirement jitters to higher Social Security benefits and lower taxes a decade or more down the road.

That's because the array of rules and figures outlined in the slideshow below add up to complex calculations that vary greatly among clients whose financial advisors and tax professionals may want to consider the so-called bridge strategy. The idea revolves around how clients can take IRA distributions in pre-retirement in order to avoid facing required minimum distributions later while gaining the cash flow necessary to delay Social Security until the payments are bigger.

The thicket of financial calculations, IRS guidelines, Medicare rules and long-term planning involved with deciding when to begin withdrawals and Social Security benefits shows the need for careful, individualized advice, according to four experts who spoke with Financial Planning. 

The last two months of a year mark an especially good time to discuss the possibilities of the bridge with clients. Prior to New Year's Day, factors such as the level of capital gains, investment dividends, business-related transactions or job situations are coming into focus, said Valerie Escobar, a senior wealth advisor with Kansas City, Missouri-based advisory practice BMG Advisors. Advisors and their clients can weigh them against the possible IRA distributions.

"As we're approaching the end of the year, you have a better sense of what your income picture is going to look like," Escobar said. "Having that clarity of the picture makes the year-end the best time to be looking at that."

The fourth quarter "is the most important time to be looking at your taxes" because "it's the last chance you have to fix things," said Erin Wood, a senior vice president for financial planning and advanced solutions with Omaha, Nebraska-based registered investment advisory firm Carson Group. Client decisions on when to take required minimum distributions and when to begin claiming Social Security can have major consequences — including on their spouse's survivor payments or the size of their monthly benefit checks (clients could see a bump of 8% a year if they wait until age 70).

"Those are a great example of something that you really only get one chance to make the right decision," Wood said. "Once you make your decision, you are very much going to be stuck with that decision."

In addition, those considerations often determine whether clients get stuck with "stealth taxes" on their benefits and whether they have to pay an income-related monthly adjustment amount on their Medicare premiums according to Sarah Brenner, the director of retirement education with retirement consulting firm Ed Slott and Company.

Once traditional IRA owners reach 59½ years old — or the age they must be to avoid getting "whacked with a 10% penalty" for a withdrawal, unless they're for certain exceptions — they're going to be thinking through how the distribution affects their income.

"It bumps up what you're going to pay for Medicare," Brenner said. "One thing they hate is IRMAA charges."

Other than a general rule that claiming Social Security benefits while still employed is not usually a good idea, Heather Schreiber, the founder of advanced planning consulting firm HLS Retirement Consulting, said she had no one-size-fits-all standard timeline for beginning the payments.

"First of all, I'd say, 'Don't listen to your neighbor,'" Shreiber said. "Everyone's decision is very unique to them. I really don't have an, 'Everyone should file at X date.'"

Calculating Social Security benefits

The Social Security Administration provides benefits calculators enabling people of any age to see the amount of their projected monthly payments. The amount comes from a mean of 35 years worth of earnings indexed for inflation for each worker that result in a number known as their "average indexed monthly earnings" that form an equation leading to another figure called their "primary insurance amount," according to the agency. The amount of benefits depends on yearly changes to the national average wage index that alter which parts of the average monthly earnings are calculated into the primary insurance amount.

Income taxes on Social Security benefits

For 2024, nine states will charge some residents income taxes on their Social Security benefits and roughly 40% of recipients must pay federal duties on their benefits. 

A number known as "combined income" that is a taxpayer's adjusted gross income plus nontaxable interest and half of their level of Social Security benefits will decide the level of federal taxation, according to the SSA.

For individuals:
  • Combined income between $25,000 and $34,000: Up to 50% of benefits may be taxable.
  • Combined income of more than $34,000: Up to 85% of benefits may be taxable.
For spouses filing jointly:
  • Combined income between $32,000 and $44,000: Up to 50% of benefits may be taxable.
  • Combined income of more than $44,000: Up to 85% of benefits may be taxable.

The ‘full retirement age’ impact on Social Security benefits

Americans may begin receiving their Social Security retirement benefits as young as 62, but they won't get the highest technical amount until they reach their "full retirement age," according to the SSA.

  • For birth years 1943 to 1954, the FRA is 66. Claiming at 62 reduces benefits 25%.
  • For 1955 birth, the FRA is 66 and 2 months. Claiming at 62 reduces benefits 25.83%.
  • For 1956 birth, the FRA is 66 and 4 months. Claiming at 62  reduces benefits 26.67%.
  • For 1957 birth, the FRA is 66 and 6 months. Claiming at 62  reduces benefits 27.5%.
  • For 1958 birth, the FRA is 66 and 8 months. Claiming at 62 reduces benefits 28.33%.
  • For 1959 birth, the FRA is 66 and 10 months. Claiming at 62 reduces benefits 29.17%.
  • For 1960 or later birth, the FRA is 67. Claiming at 62 reduces benefits 30%.

Working while receiving Social Security benefits

Working while receiving Social Security benefits doesn't pay dividends before the full retirement age. In fact, it's quite the opposite, according to the SSA.

  • If the client is younger than full retirement age, $1 is removed from benefits for every $2 earned over $22,320.
  • In the year of the client's full retirement age, $1 is removed for every $3 earned above $59,520. 
  • Starting in the month of full retirement age, there are no limits-based penalties to benefits.

The incentive of waiting past full retirement age for Social Security benefits

Social Security retirement benefits climb even more in each month past the full retirement age that beneficiaries wait to begin payments, up until they turn 70, according to the SSA.

  • Those born in 1933 or 1934: increase of 11/24 of 1% every month or 5.5% per year.
  • Those born in 1935 or 1936: increase of ½ of 1% every month or 6% per year.
  • Those born in 1937 or 1938: increase of 13/24 of 1% every month or 6.5% per year.
  • Those born in 1939 or 1940: increase of 7/12 of 1% every month or 7% per year.
  • Those born in 1941 or 1942: increase of ⅝ of 1% every month or 7.5% per year.
  • Those born in 1943 or later: increase of ⅔ of 1% every month or 8% per year.

Estimating required minimum distributions

An IRA's owner's year-end account balance divided by the life expectancy listed on the current IRS "uniform lifetime table" will determine the amount of the required minimum distribution in most cases. Under the current rules, pre-retirees won't need to start RMDs until they're 73. And by 2033, they'll be able to wait until they're 75.

Here are the life expectancies for 2024 based on the IRA owner's age, up to 100.

  • Age 72: Distribution period of 27.4 years
  • Age 73: Distribution period of 26.5 years
  • Age 74: Distribution period of 25.5 years
  • Age 75: Distribution period of 24.6 years
