Can you prepay real estate tax before the new law kicks in?

WASHINGTON — Homeowners in the D.C. area with some extra money on hand are hustling to prepay their 2018 property taxes before the new tax law takes effect Jan. 1.

The new federal law caps deductions at $10,000 for all combined state and local taxes, including both income and property taxes. That means owners of expensive homes and cars have only one more chance to avail themselves of healthy deductions.

The prospect of losing that valuable deduction has prompted homeowners to inquire whether they can prepay future property taxes before the limitations of the new law.

Despite the interest, tax experts have not determined that prepayment will benefit all homeowners.

On Wednesday, the IRS released a statement explaining that “whether a taxpayer is allowed a deduction for the prepayment of state or local real property taxes in 2017 depends on whether the taxpayer makes the payment in 2017 and the real property taxes are assessed prior to 2018.  A prepayment of anticipated real property taxes that have not been assessed prior to 2018 are not deductible in 2017.”

The question of when property tax is assessed is up to “state and local law,” the IRS said.

The City of Fairfax, Virginia, allows prepayment of property tax, but in a statement Wednesday evening, the city government said that the IRS announcement “means that such prepayments of 2018 taxes to the city may not be deductible in 2017 and city officials will immediately review options for refunds as appropriate.”

The laws in other counties and cities in the D.C. area may be structured in such a way that prepayments are deductible; taxpayers will need to contact their tax professionals or county governments.

City of Alexandria

“We’ve always taken prepayments,” said Craig Fifer, spokesman for the City of Alexandria. “What’s new is the level of interest this year.” By Saturday, Fifer said, the city had received more than $1.6 million in prepayments. While payments can be made online, Fifer said the city prefers payments by check, with the word “prepayment” included. Payments can be placed in a drop box at City Hall.
