The recent wave of property tax appeals filed by U.S. Steel has left several municipalities in Pennsylvania’s Mon Valley scrambling for resources. From North Braddock to West Mifflin, communities report a combined loss of more than $1 million in annual tax revenue, even as the steelmaker pours billions into upgrades at its Mon Valley Works sites following the Nippon Steel acquisition.
County officials are still awaiting a comprehensive reassessment that could mitigate some of the shortfalls, but in the meantime local leaders must decide how to stretch dwindling budgets while still providing essential services.
North Braddock and adjacent boroughs feel the pinch
North Braddock, a 1.5-square-mile borough bordering Pittsburgh, sees roughly 11 % of its real-estate tax intake come from the Edgar Thomson Plant. Prior to the 2025 appeals, the plant generated about $79,000 in tax revenue; the new assessment reduces that figure to $34,000, a $45,000 drop. Borough manager Cory Ruff summed up the mood: “We’re just kind of left trying to figure out how to do the best we can with what we have left.”
The shortfall forced the borough to abandon plans for a new code-enforcement officer—a position that would also have served East Pittsburgh and Braddock. Since the start of the year, North Braddock alone has recorded roughly 400 code violations, a workload that now falls on an already thin staff.
Braddock and surrounding townships
In Braddock, the loss of assessed value at the Edgar Thomson site—down from $58.5 million to $33.7 million—translates to an estimated $39,000 less in yearly property taxes, based on the borough’s 13.65-mill rate. Similar reductions are felt in East Pittsburgh and North Versailles, which share the plant’s footprint.
Settlement and credit arrangement with U.S. Steel
U.S. Steel’s spokesperson Amanda Malkowski described the agreement with municipalities and school districts as a “practical resolution” that avoids prolonged litigation. Instead of receiving the typical partial refunds that accompany lowered assessments, the company elected to forgo refunds on more than 50 of its highest-value parcels for the past two years. Those amounts were then applied as a tax credit toward the company’s 2026 and 2027 bills.
“Importantly, we agreed to forgo significant refunds associated with prior tax years so that school districts and municipalities would not experience significant impacts to existing operating budgets,” Malkowski said. The settlement means that for the next three years, North Braddock will receive only half of its newly assessed $34,000 bill, a total loss of $175,000 compared with pre-settlement levels.
West Mifflin, school districts and broader regional impact
West Mifflin bears the brunt of the reassessment, with an estimated $11 million drop in taxable value across its U.S. Steel-owned parcels. The borough’s manager, Brian Kamauf, warned that the loss translates to $127,000 less in annual tax revenue, but assured residents that essential services will not be cut. Still, the West Mifflin Area School District reports a $273,000 per-year reduction from 13 appealed parcels, prompting a modest tax hike earlier this year.
School districts farther east are also adjusting. The Woodland Hills School District, which spans twelve communities and includes the Edgar Thomson Plant in its tax base, projects a $50.2 million property-tax take for 2026-27—up from $47.3 million the prior year—by raising its millage rate to 29.08 mills. Even so, the decline in U.S. Steel’s assessed value by $6.7 million carves out a $197,000 loss, less than 1 % of the district’s total revenue.
In Clairton, the city and its school district together lose about $383,000 annually after the Coke Works’ assessed value fell by $5.7 million. The city relies on U.S. Steel for roughly one-third of its tax base, a fact highlighted by former mayor Rich Lattanzi.
Despite the fiscal strain, many local officials note that U.S. Steel continues to contribute to community projects—ranging from utility vehicle donations to annual toy drives—and has pledged up to $3 billion in upgrades at the Edgar Thomson Plant. Yet no comparable investment has been announced for the Irvin Works or Clairton facilities.
Legal experts, such as municipal attorney Lee Dellecker, describe the credit arrangement as “not a typical resolution,” noting that it may have been pushed by the hardest-hit municipalities that could not afford to refund the steelmaker. A pending Allegheny Court of Common Pleas decision, which mandates a full countywide reassessment by 2032, could bring greater uniformity to property valuations, potentially easing future budgeting surprises.
For now, borough leaders across the Mon Valley must juggle reduced revenues, delayed infrastructure projects, and the challenge of maintaining public safety and code-enforcement capacity—all while watching the next chapter of U.S. Steel’s investment plans unfold.
