Property taxes increased on more than half of Montgomery County’s residential parcels this year, a repercussion of a countywide reappraisal that saw property values climb by double digit percentages for a majority of owners.

“Draconian” is how Mark Tarjan described the 43% increase in value on the home he owns with his wife in Miami Twp.

“I usually don’t throw words like that around, but it seems a little extreme to me,” said Tarjan, whose annual tax bill on his 1,215-square-foot ranch home went up $1,043, or nearly 30%.

“It took me by surprise,” said the graphic artist now working from home due to the pandemic.

Tarjan is hardly alone.

He’s one of the 1,002 property owners who as of Thursday had filed a formal dispute with the county’s Board of Revision since final valuation notices and tax bills went out three weeks ago. Tentative values mailed out in August prompted owners of 4,021 parcels to ask the auditor for an informal review. Nearly half — 1,982 — resulted in the county decreasing the taxable value; 1,805 were unchanged; and 234 resulted in an increase.

Property owners have until March 31 to file an appeal with the county’s Board of Revision.

“You would think given the level of increases that we saw that we would get a record number of appeals. But it’s too early to tell,” Keith said.

The county’s Board of Revision heard a record 7,688 cases in 2009 following the 2008 reappraisal. Residential values went up 4% just as homeowners were reeling from a market downturn now known as the Great Recession.

Jeff Spisak said the tax value of his family’s Washington Twp. home jumped 13.7% to $640,490. While that increase is less than the 15.5% average countywide, he said that’s still far higher than he could sell it for in his neighborhood.

“I couldn’t sell our house for $530,000, let alone $630,000,” he said.

Spisak said an appraiser he hired placed the home’s value at $500,000.

“I realize they’re down on their money, but if you keep jacking up the property values no one’s going to live here anymore and you’re going to end up with a bunch of vacant houses,” he said.
