Real Estate Taxes and Considerations for Tax Appeal

Real property taxes are a significant source of income for local authorities. Generally there are three main taxes levied on real property in Pennsylvania:

  • County Taxes
  • Municipal Taxes
  • School Taxes

Several municipalities have other real property taxes including library, fire services, and several other community amenities that may be in addition to or built into the taxes above.

Pennsylvania assessment laws require that real estate be valued according to its "actual value" and at a bona fide rate and price for which the property would separately sell, which is interpreted as market value. Therefore properties are assigned an assessment value.

The assessed value and the appropriate millage rate is used to calculate real estate taxes. Millage rates are the amount per $1,000 that is used to calculate taxes on property. County millage rates are the same for all municipalities in the county, while the municipal and school taxes vary by municipality and school district. The assessed value is multiplied by the millage rate to calculate the tax expense for a property.

In most counties taxes are due twice a year. In late winter/spring the County and Municipal taxes are sent to taxpayers and in mid-summer the school taxes are sent to taxpayers.

Are Taxes Appropriate for Property Value

A 'base year' establishes an assessed value equal to market value for properties within each county. However as property values increase or decrease over years, the assessment value remains unchanged for a property. To reflect market value using the 'fixed' assessment value, a common level ratio is established annually for each county. A common level ratio (CLR) is: 'the ratio of assessed value to current market value used generally in the county as last determined by the State Tax Equalization Board (STEB)." The common level ratio factor is the reciprocal of the common level ratio. A common level ratio of .98 would be equivalent to a common level ratio factor of 1.02 (1 ÷ 0.98). If a property is assessed for $450,000 and the county has a common level ratio factor of 1.02, the 'implied' market value is $459,000 ($450,000 x 1.02). Or, if a property is assessed for $450,000 and the common level ratio factor is 0.90, the implied market value is $405,000 ($450,000 x 0.90).

Note, counties do not typically re-assess each year. When a county has a re-assessment, the common level ratio factor is 1.00 and is considered the new base year. Following are the current common level ratio factors for several South Central Pennsylvania counties:

County CLR Appeal Deadline Last Re-Assessment
Adams .96 August 1 2010
Cumberland 1.08 September 1 2010
Dauphin 1.57 August 1 2001
Lancaster 1.2 August 1 2018
Lebanon 1.14 September 1 2013
Perry 1.14 September 1 2010
Franklin 9.09 August 1 1961
York 1.24 August 1 2006

*CLR Factors as of January 2021

When considering a tax appeal, the 'implied market value' is calculated using assessed value and the common level ratio factor. This amount is then compared to actual market value of a property. If the implied market value exceeds the actual market value, a tax appeal may be warranted. Other factors to consider when deciding to appeal your real estate taxes is how much money will you actually save compared to the cost of filing an appeal. Tax appeal costs include the initial filing fees, possible appraisal fees and possible attorney/legal fees. Not all tax appeals are successful so there is the risk of no change to your assessed value or your annual real estate taxes. Each county has an appeal deadline when all appeals for the following year must be submitted for consideration for taxes for the next year. Above is the deadline for each county.

Covid-19 Observations

The start of 2020 marked approximately ten years of real estate market growth, both in the residential and commercial sectors. This period of economic growth had been one of the longest in more recent history. Many had predicted a slow-down with stable market conditions in 2020 – that was until Covid-19.

The Coronavirus pandemic (Covid-19) came into world view during late 2019 and early 2020. In February 2020, the severity of the virus came into focus and the United States began seeing more cases and deaths. In Mid-March the Country ‘shut down’ for a two-week period in an attempt to stop the spread of the virus. The two-week period turned into months, and states eventually began re-opening at varying times and at different levels. Late spring saw a slow-down, however as business and ‘life’ opened up the summer months saw a resurgence of cases and deaths. This was followed by a brief slowdown of increases in cases and deaths in late summer, early fall in some parts of the Country. As predicted by health leaders, the second wave hit hard in late fall and into early 2021, significantly increasing the number of United States hospitalizations and deaths.

To date, cases have slowed and with the roll-out of the vaccine, many are hopeful that by summer or early fall life may resume to some degree of normalcy.

The impact of Covid-19 on the commercial real estate market has short-term and long-term effects. The short-term effects vary by market sector and type of property. The full extent of the long-term impact is yet unknown. Next we discuss some of the short-term effects impacting property value and touch upon key points that may have an impact in the long-term.

Short-Term Effects on Market Sectors: First, a point to be made regarding the short-term (and long-term) impact is the length of time that Covid-19 has lingered and imposed a threat. In 2020 when the virus came into focus, most of America believed it to be a few-month event that could be contained and would quickly be eradicated. This obviously proved false, and most predictions were dependent on the duration of the virus. So short-term in our definition is defined as through the beginning of 2021.

  • Industrial Market – The industrial market has remained strong and has felt minimal impact from the virus, except initial interruptions during the initial shut-down. E-commerce has fueled the manufacturing and distribution industrial market. Overall there has been minimal to no negative short-term impact on the industrial market.
  • Office Market – Short term impact has been moderate. Although many office workers are working from home, companies have maintained their office space. There has been some foot-print downsizing and some rent concessions, however the impact has been moderate to date. This market sector may be more impacted in the long-term as described below.
  • Apartment Market – The apartment market has remained strong overall. Higher-rent apartment owners are reporting minimal disruptions in payment and collection loss. Lower-rent apartments have felt a greater impact with increased collection loss. This disparity is consistent with the types of jobs that have been impacted.
  • Retail Market – This market sector varies by product type. ‘Essential’ businesses have had strong earnings during 2020. Home goods stores, exercise equipment, furniture sales are among those reporting record years. Whereas restaurant and bar businesses, which were thriving prior to the pandemic, have been significantly impacted. We spoke with several restaurant owners who could not have survived without PPP money. There are restaurants and bars that have not and will not survive in the short-term.
  • Hospitality Market – This market sector has felt the most significant impact of all market types. The hospitality market had several prosperous years prior to the pandemic. The virus had a huge impact on travel, greatly increasing vacancy rates for hotels. Economists predict this market will have the longest recovery of all market sectors. The short-term impact has been devastating for this market sector.

Long-Term Effects on Market Sectors: As stated above, the length of the impact on ‘normal’ life due to the virus will play a role in determining long-term effects on the commercial real estate market. Future economic impacts on real-estate are always unknown, and the future impact from Covid-19 remains speculative.

Although no one is certain of the full impact on the commercial real estate market, there are some key points for discussion that may shed some light on future impact.

  • Industrial Market: This market sector is anticipated to remain strong in the long-term. The primary potential impact is an overall slow-down in the economy due to permanent lost jobs that impacts the purchasing power of consumers.
  • Office Market: This market sector remains the most speculative. Much depends on the success of productivity from the work-at-home scenario. There has been much discussion about working from home, with both negative and positive feedback. Predictions lean more towards increasing vacancies in the upcoming years and a negative impact in the long-term.
  • Apartment Market: The long-term impact is anticipated to be minimal to moderate. Due to an overall economic slow-down rental rates may be slow or remain stable. A large shift in this market is not anticipated and conditions are predicted to remain economically strong. Sales that occurred during the pandemic support this future expectation as prices have not dropped.
  • Retail Market: While this market was hit hard in the short-term, the long-term picture is brighter. Pent-up demand for eating out and purchasing is expected to boom after Covid-19 is contained. Those businesses that were able to survive the short-term impact will likely benefit in the long-term. We note here that prior to Covid-19 some retail market sectors were struggling due to e-commerce, and the habits of shoppers continues to impact this market sector outside the Covid-19 influence.
  • Hospitality Market: Because of the drastic short-term impact this market sector is anticipated to have a much longer recovery time. Whereas office space had long-term leases in place, and retail had e-commerce and ‘take-out’, this sector has no backup plan. When travel resumes it is expected to slowly build and based on overall slow-down effects from Covid-19 may not return to pre-Covid 19 levels for some time.
