Starting in the late 1980's, the Social Security Administration received a flood of W-2 earnings reports with incorrect - sometimes simply fictitious - Social Security numbers. It stashed them in what it calls the "earnings suspense file" in the hope that someday it would figure out whom they belonged to.
The file has been mushrooming ever since: $189 billion worth of wages ended up recorded in the suspense file over the 1990's, two and a half times the amount of the 1980's.
In the current decade, the file is growing, on average, by more than $50 billion a year, generating $6 billion to $7 billion in Social Security tax revenue and about $1.5 billion in Medicare taxes.
In 2002 alone, the last year with figures released by the Social Security Administration, nine million W-2's with incorrect Social Security numbers landed in the suspense file, accounting for $56 billion in earnings, or about 1.5 percent of total reported wages.
Social Security officials do not know what fraction of the suspense file corresponds to the earnings of illegal immigrants. But they suspect that the portion is significant.
"Our assumption is that about three-quarters of other-than-legal immigrants pay payroll taxes," said Stephen C. Goss, Social Security's chief actuary, using the agency's term for illegal immigration.
Illegal immigrants help even more because they will never collect benefits. According to Mr. Goss, without the flow of payroll taxes from wages in the suspense file, the system's long-term funding hole over 75 years would be 10 percent deeper.
Yet to immigrants, the lack of retirement benefits is just part of the package of hardship they took on when they decided to make the trek north
