CHERRY HILL, N.J.  — In a season of sales, homeowners in affluent towns across the country are rushing to take advantage of a deal that they hope will save them big.

On taxes.

Tax collectors in many communities are seeing a surge in property tax prepayments before 2018 in an effort to cash in — for one last year — on a deduction that the coming tax overhaul will limit.

The tax office at the Cherry Hill Township building in New Jersey saw a steady stream of property owners on Friday.

One man said his buddies at an early-morning hockey game said it would be a good idea to prepay. A couple was there because their accountant called to recommend it. And Ron Brand — an accountant, though he doesn’t do other people’s taxes — was there with $15,000 to pay a full year’s worth of 2018 property taxes.
