How Bad Would Eliminating Social Security’s Deficit Feel?


Alicia Munnell, the director of the Center for Retirement Research at Boston College, is a weekly contributor to “Encore.”

Each year the trustees of the Social Security system report on its financial health over the next 75 years.  The 2011 report shows that, despite reduced revenues and increased benefit claims in the short run, the system continues to face a 75-year deficit equal to about 2% of taxable payroll (click on figure below and to your right).

The shortfalls over the last two decades are in sharp contrast to the projection of a 75-year balance in 1983 when Congress enacted the recommendations of the so-called Greenspan Commission.  The table below shows the reasons for the shift from a 0.02 surplus in 1983 to a deficit of 2.22% in 2011.  Leading the list is the impact of changing the valuation period.  That is, the 1983 report looked at the system’s finances over the period 1983-2057; the projection period for the 2011 Report is 2011-2085.  Each time the valuation period moves out one year, it picks up a year with a large negative balance.  Persistent increases in disability rolls and worsening economic assumptions – primarily a decline in assumed productivity growth and the impact of the recent recession – also contributed to the deficit.   Changes in demographic assumptions – primarily higher mortality for women – and the effect of regulation and legislation, such as the Affordable Care Act of 2010, have partially offset the negative factors.

Reasons for Change in Social Security 75-Year Deficit as a Percent of Payroll, 1983-2011

Item Change
Actuarial balance in 1983 0.02
Changes in actuarial balance due to:
Valuation period -1.63
Disability data and assumptions -0.68
Economic data and assumptions -0.54
Projection methods and data -0.11
Demographic data and assumptions 0.44
Legislation/regulation 0.30
Other factors* -0.02
Total change in actuarial balance -2.24
Actuarial balance in 2010 -2.22

Is a 75-year deficit of 2.22% of taxable payrolls big or small?  One way to think about it is the amount by which the payroll tax would have to increase for the government to be able to pay the current package of benefits for everyone through 2085.  That is, if payroll taxes were raised immediately by 2.22 percentage points – 1.11 percentage points each for the employee and the employer – the system would be in 75-year balance.

How bad would a 1.1 percentage-point increase in the payroll tax feel?  We could be about to find out.  The Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 reduced the Social Security payroll tax rate for 2011 by 2 percentage points for employees and the self employed.  (The Treasury makes up for this reduction by reimbursing the trust funds from general revenues, so it has no financial implications for Social Security’s short- or long-term outlook.)  The tax is scheduled to rebound to its original level in January 2012.  (Whether such an increase will actually occur in an election year is another story, particularly since extending the payroll tax cut has been discussed in the ongoing budget negotiations.)  Thus, the scheduled increase for employees in 2012 is twice the size of that required to restore balance for 75 years.  Assuming the increase does occur, it will be interesting to see if anyone even notices.

One final note, a lasting fix for Social Security would require that the payroll tax increase be accompanied by some other changes.  Solutions that provide just enough to restore balance for the next 75 years leave the system in deficit in the 76th year.  The most logical adjustment on the benefit side would be to index the full retirement age (after it reaches 67) to improvements in longevity.   Those two changes – a 1-percentage-point increase in the payroll tax for employees and employers and indexing the full retirement age to longevity – would take us a long way towards a permanent solution.  And I bet that it would be almost painless.

    • Most of the education setysm has a huge amount of inertia built into it. Adding a new subject, no matter how important, needs a lot of public pressure to over come the objections of setysm. Often time the only way to get a change is to get the state officials to put it on the standardized high school graduation test.There has been some progress in some states / cities.

    • I think something missed in this discussion, is that we’re talking about the age at which someone can collect their full benefits. That has little to do with the age they retire from full time work. I’m 48 and just quit my full time job, because I can afford to. At my age, full retirement for SS is 67, so I’ve got 19 years to go before I collect (assuming I don’t opt to file early) SS should only be a portion of your retirement income, so you should be able to make it to 67, 68 before you start collecting on that. I’ve only made over $50k once, and I don’t have an expensive lifestyle, but it shows that it can be done. Like any other sensible program, it should be adjusted from time to time to reflect realities. Save your butt off, and chill out!
