The Salt Lake County treasurer's office began mailing about 252,000 notices for 1991 property taxes Tuesday, including forms to register for monthly property tax payments.

Treasurer Art Monson said approximately 1,600 county property owners have registered to pay their property taxes by the month since the program was created one year ago.The monthly payment plan was designed for people on fixed incomes whose yearly tax burden might be unnecessarily burdensome when it came due all at once at the end of the year. But Monson said people of "considerable wealth" and professional property managers have also showed an interest in the program.

Mailings containing the 1991 tax notices will contain information about the monthly property-tax payment plan and a registration form that gives property owners the option of paying with monthly coupons or by authorizing an automated bank withdrawal.
