WASHINGTON (PAI) — Tax filing for union members is free if your adjusted gross income is under $28,500 with the new Union Plus online tax service. For other union members, the service costs $21.95 — half the cost of Quicken’s Turbo-Tax computer program or of (nonunion) H&R Block.

The service, launched Jan. 17, is easy to use. Log on to www.unionplus.org, answer some simple questions posed by the program, enter the information requested, and relax. The program does the math, even checking for errors.

Unlike other computer tax programs, Union Plus says it bans come-ons and pop-up ads. Refunds are deposited, usually within two weeks, directly into your checking or savings accounts. Also unlike many other tax preparers, Union Plus charges no high-cost “rapid refund” service fees.
