The state’s school tax rebates appear to be going out relatively quickly this year.

About 350,000 New Yorkers have received Property Tax Relief Credit checks in the past three weeks, according to the state Department of Taxation and Finance.

“The fact that it’s done this way raises some eyebrows,” said David Friedfel, director of state studies for the Citizens Budget Commission, a fiscal watchdog group.

State officials have noted that sending out the checks this time of year can help people pay their school taxes, which are typically due in September. Still, Friedfel noted that most people with mortgages have their school taxes collected through escrow accounts that are part of their monthly mortgage payments.
