What Is the Legislative Mandate for the Annual Report?

1) Trust Fund operations of the past year and the 

next five years

2) Actuarial status of the trust funds

– This means the ability to meet the cost of scheduled 

benefits with scheduled revenue and trust fund 

reserves

– And the extent to which scheduled revenue will fall 

short, forcing cuts or delays in benefits in the absence 

of legislative change

SOLVENCY: OASDI Trust Fund Reserve Depletion 2034 (same as last year)

o Reserve depletion date varied from 2029 to 2042 in reports over the past 25 years (1992-2017) 

o DI Trust Fund — reserve depletion in 2028, five years later than last year

o Due largely to lower recent and near-term disability applications and incidence rate

Applications for Disability Benefits Continue to Fall

At the peak of the last economic cycle in 2007, applications were low, but increased 

rapidly in the recession to over 2 million in 2010. In 2016, with the economy still below 

the sustainable full-employment level, applications have dropped below the 2007 level

The Bottom Line

• Long-term projections provide information to assess 

solvency and changes needed to eliminate shortfalls

• If trust fund reserves were to deplete:

– Full benefits cannot be paid timely

– NO pressure on the Budget or Federal Debt

– So Congress must and WILL act, as always

• Straightforward solutions:

– Add revenue and/or lower cost for OASDI

• Comprehensive changes implemented by 2034
How to Fix Social Security Long-Term

Make choices addressing OASDI deficits 2034-2091:

• Raise scheduled revenue after 2033 by about 

33%: increase revenue from 4.6 to 6.1% of GDP

• Reduce scheduled benefits after 2033 by about 

25%: lower benefits from 6.1 to 4.6% of GDP

• Or some combination of the two

• Invest trust funds for higher return? 

– Limited help—it is a PAYGO world

–So invest in coming generations of workers

21
Ways to Lower Cost

• Lower benefits for retirees—not disabled?

– Increase normal retirement age (lowers OASDI cost, but 

increases DI cost)

– Can exempt long-career low earners

• Lower benefits mainly for high earners?

– Reduce PIA above some level

– Often combined with increasing PIA below some level, subject to 

work year requirements

• Lower benefits mainly for the oldest old?

– Reduce the COLA

– Some say increase it with the CPI-E (based on purchases of 

consumers over age 62

22
Ways to Increase Revenue

• Raise tax on highest earners?

– Increase taxable maximum amount

– Some tax on all earnings above the maximum

• Tax employer group health insurance premiums?

– Affects only middle class if taxable maximum remains

• Maintain larger trust fund reserves?

– Added interest can lower needed taxes
