New Jersey Gov. Phil Murphy signed a law Friday that will allow homeowners in the state to declare property taxes as charitable donations. The state law, which had broad bipartisan support in the state, was in response to the tax-law changes passed late last year by congressional Republicans, which capped the state and local tax deductions in federal filings at $10,000. Governors in higher-tax, higher-property-value states, most of whom are Democrats, had vowed to fight the law by coming up with workarounds like the one adopted in New Jersey. At the time, New York Gov. Andrew Cuomo called the tax law "economic civil war." On Friday, Murphy, also a Democrat, said of the federal legislation, "It is divisive, it is wrong, and we will continue to fight." In fact, many legal and tax analysts believe New Jersey will have to fight the IRS in court after taking this step. The law will allow property owners to donate up to 90% of their tax bill to charitable funds set up by municipalities in exchange for tax credits.
