Most colleges in Boston are falling short when it comes to paying the city what it requests as compensation for municipal services.

Under a 4-year-old program, the city asks nonprofits with more than $15 million worth of tax-exempt property to voluntarily help offset the cost of police and fire protection, snow removal, and other services through the PILOT program — payments in lieu of taxes.

The Boston Globe ( ) reports that according to data released Tuesday, of the 19 colleges in the program, 13 paid less than requested during the just-ended fiscal year.

Two small schools paid nothing. Six schools, most of them smaller paid 100 percent. Tufts was among those that paid the full amount.

Boston University paid 86 percent; Harvard paid 44 percent; Boston College 23 percent; and Northeastern 13 percent.
