The order affects the owners of roughly half a million properties across Allegheny County.<\/p>\n<p>It is intended to bring greater consistency to a system that has long faced criticism for being antiquated and unfair.<\/p>\n<p>So what does that mean for you? Will your property\u2019s assessed value go up or down? Could your tax bill change?<\/p>\n<p>Here are four things you need to know about Allegheny County\u2019s mandated property reassessment.<\/p>\n<p>The basics: What is a reassessment, and<br \/>\nwhy is it needed?<\/p>\n<p>Property reassessments act as a reset of the values used to calculate property taxes. Allegheny County determines what properties are worth based on current real estate conditions, said Mike Suley, chair of the Allegheny County Board of Property Assessment Appeals and Review.<\/p>\n<p>A property\u2019s assessed value is then used by local taxing bodies \u2014 such as the county, municipalities and school districts \u2014 to calculate a property tax bill.<\/p>\n<p>Property values change over time, as neighborhoods develop, homes get renovated or deteriorate and real estate prices rise and fall. Suley said that if assessed values stay frozen for years, they can become increasingly disconnected from what the properties actually are worth, which can create an uneven tax system.<\/p>\n<p>\u201cA lot of the assessments are way out of whack. You can go up and down any street in Allegheny County and see the disparity in the tax bills,\u201d Suley said. \u201cThere are tens of thousands of people right now paying more than they should be paying, and they don\u2019t even know it.\u201d<\/p>\n<p>For example, Suley explained that two people could live in identical 2,000-square-foot condos in the same building yet face drastically different tax bills. One owner might pay about $8,000 a year while the other pays $16,000, a disparity he said that does not make sense.<\/p>\n<p>The misconception: Do reassessments guarantee a tax increase?<\/p>\n<p>Suley said there is a common misconception reassessments are a guaranteed tax increase. He stressed state anti-windfall protections ensure the scale stays balanced.<\/p>\n<p>Essentially when one thing goes up, another must come down.<\/p>\n<p>Property taxes are calculated by the value of a property and the tax rate set by each taxing body. Allegheny County pays for county government services, a municipality pays for local government services and the school district pays for public schools.<\/p>\n<p>The county determines an assessed value of the property. That value is different from what the property might be able to sell for today.<\/p>\n<p>Under the current system, the county bases assessment on 2012 property values. A state-calculated percent called the \u201ccommon level ratio\u201d is used to compare a county\u2019s older assessed property values with current open-market real estate prices.<\/p>\n<p>Then, the three different taxing bodies can apply a millage rate to that assessed value.<\/p>\n<p>A mill is $1 in tax for every $1,000 of assessed property value. So, if a property has an assessed value of $100,000 and the school district\u2019s millage rate is 30 mills, the property owner would owe $3,000 in school property taxes.<\/p>\n<p>Under state law, if aggregate assessed values rise, the millage rate must drop in proportion, yielding the same tax revenue and <a href=\"https:\/\/alleghenycontroller.com\/the-controller\/property-tax-watch\/\" target=\"_blank\" rel=\"nofollow noopener\">avoiding a windfall<\/a>, Suley said.<\/p>\n<p>Members of Allegheny County Council have been on a crusade for a bill that would standardize reassessments in the county to every three years beginning in 2028. This summer, council held a handful of public hearings at different locations around the county. During these meetings they stressed this point.<\/p>\n<p>\u201cLegally every single taxing body will have to, after the new assessed values hit, adjust the millage rate. They legally have to. So that\u2019s your municipality, your school district, and the county,\u201d said County Councilwoman at-large Bethany Hallam, D-North Side, at a public hearing on June 3.<\/p>\n<p>Suley said property values are not necessarily relevant to residents\u2019 concerns about higher taxes.<\/p>\n<p>If the millage rate were cut in half, a homeowner\u2019s tax bill would generally fall by half only if the assessed value remained the same. Conversely, Suley said, if the millage rate increased, assessed property values could offset that increase.<\/p>\n<p>This would mean a homeowner could potentially pay less in taxes despite a higher rate.<\/p>\n<p>The math: Can you predict a property\u2019s reassessed value using common level ratio?<\/p>\n<p>Suley said there is no way to know how a property will be impacted by the reassessment \u2014 because the homes that will establish the market value for the mandated reassessment have not sold yet. Therefore, there is no way to calculate whether a property\u2019s taxes will go up or down.<\/p>\n<p>The order reassessment will replace the existing 2012 base values, with data to be gathered beginning in 2027 and completed within five years. The reassessment determines the home\u2019s relevant market value based on sales occurring during that period.<\/p>\n<p>While it may appear as though a homeowner could do the math to form a prediction, the county\u2019s current 49.3% common level ratio cannot simply be plugged into a calculation. Part of the information needed \u2014 the market value \u2014 has not yet been determined.<\/p>\n<p>\u201cLook, I\u2019m an expert. And I don\u2019t know \u2014 I can\u2019t predict what homes they\u2019re going to be selling for in three, four years,\u201d Suley said. \u201cSo anyone who\u2019s doing that shouldn\u2019t be doing that.\u201d<\/p>\n<p>The right to appeal: What if the county gets it wrong?<\/p>\n<p>The first step in performing a new assessment is defining the county\u2019s neighborhoods, so that an assessor understands which properties are comparable and how values vary from one area to another.<\/p>\n<p>The assessor then looks at the condition of the property, its size, its physical characteristics and the quality of its construction. To do this doesn\u2019t mean the assessor necessarily has to walk through the home, Suley said.<\/p>\n<p>Instead, the information can be gathered by looking at the exterior, existing records and aerial photography. That information then is used to create a sketch of the property.<\/p>\n<p>\u201cIn the 2012 reassessment, this is very important. We did a data collection. We changed 300,000 sketches before we assigned new values. So that means there were probably additions or something was taken off,\u201d Suley said.<\/p>\n<p>\u201cWe haven\u2019t looked at these properties in 14 years. What we will find is the county has something listed as a vacant lot, and there\u2019s a building on it. We don\u2019t know that until we go look,\u201d he continued.<\/p>\n<p>Property owners will have the opportunity to review the information the county collects and request changes to any errors, such as an incorrect number of bathrooms or the size of the building footprint, before the new assessments are finalized.<\/p>\n<p>Once the new assessments are certified, Suley said, property owners can appeal to the county if they still feel the information is incorrect. The homeowner will need to provide evidence that the assessor\u2019s information is wrong with comparable property sales or an appraisal.<\/p>\n<p>\u201cThe goal is uniformity,\u201d Suley said. \u201cIf I have 10 identical cookie-cutter homes, all of them should receive similar tax bills.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"For the first time in more than a decade, Allegheny County is preparing to reassess the value of&hellip;\n","protected":false},"author":2,"featured_media":275675,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9],"tags":[73,75,74],"class_list":["post-275674","post","type-post","status-publish","format-standard","has-post-thumbnail","category-pittsburgh","tag-pittsburgh","tag-pittsburgh-headlines","tag-pittsburgh-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/posts\/275674","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/comments?post=275674"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/posts\/275674\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/media\/275675"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/media?parent=275674"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/categories?post=275674"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-pa\/wp-json\/wp\/v2\/tags?post=275674"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
