Summary
In the United States, property tax is the largest source of own-source revenue for local governments. Unlike property values, which fluctuate with the economy, assessed values—the basis for property tax—are not routinely updated, and reassessments generally occur infrequently. The timing of these reassessments has significant implications, particularly during economic fluctuations. For example, reassessing during periods of low property values can result in reduced revenue, requiring rate increases or service cuts. Therefore, municipalities can strategically schedule reassessments to mitigate adverse financial effects. This study investigates whether delays in property reassessment served as strategic financial management tools in North Carolina municipalities from 2000 to 2019. The results indicate that municipalities employed the timing of reassessment strategically, primarily in the periods immediately following recessions. Furthermore, municipalities that delayed reassessments had marginally higher property appraisals compared to those that did not.
- Policy Problem
According to Afonso (2026), the main political challenge discussed in the study is the tension between ensuring equity in property tax assessment and preserving the fiscal stability of local governments, especially during periods of economic recession. Although infrequent and inconsistent reassessments generate evident inequalities—as demonstrated in the Delaware court case, where properties had not been reassessed since 1974—the imposition of rigid and frequent schedules can inadvertently weaken the very fiscal resilience that makes property tax such a reliable source of revenue for local governments. Thus, the study argues that the lag between property value changes and reassessments, often treated as mere administrative inefficiency, actually functions as an important protective mechanism: it allows local governments to weather recessions without suffering immediate drops in revenue or being forced to increase tax rates during times of crisis.
Afonso also highlights a second political challenge: the balance between state mandates and local autonomy regarding the timing of reassessments. Some states have completely eliminated municipal discretion by establishing mandatory schedules, while others—such as North Carolina—allow counties to conduct reassessments at any interval, up to a maximum of eight years. The study questions whether eliminating local autonomy in the name of tax equity could harm fiscal health by depriving municipal administrators of a strategic tool for dealing with periods of economic contraction. This raises fundamental questions about the ideal design of intergovernmental policies: should states prioritize horizontal and vertical equity, imposing frequent and uniform reassessment cycles, or should they allow flexibility for municipalities to strategically schedule their reassessments, avoiding shocks to the tax base that exacerbate economic difficulties?
Finally, the third policy problem identified concerns the scarcity of empirical evidence on how local governments actually use discretion in reassessment and whether this behavior constitutes a sound financial management practice. Although academics and tax reform advocates defend more frequent and mandatory reassessments, it is still unknown whether municipalities actually strategically delay reassessments during recessions, whether such delays improve fiscal health, and whether local governments adjust their schedules over time to preserve future flexibility. Thus, policymakers face important decisions without clear evidence on the consequences of restricting local autonomy or on the potential inequalities created not only by infrequent reassessments but also by the unequal application of reassessment schedules among jurisdictions with different capacities to use this financial management strategy.
- Policy Implementation Context
According to Afonso, this study fits into an academic tradition that has long considered the reassessment of property tax a neglected area in public administration. Despite recent interest in tax inequality—with research on bias and regressivity in valuation (Atuahene & Berry 2018; Berry 2021; Rakow 2023)—little is known about the timing and flexibility of reassessments. This gap is significant: Rakow showed that controlling the timing of reassessment substantially reduces inequality estimates, indicating that when properties are assessed can be almost as important as how they are assessed.
The author reiterates that few existing studies reveal consistent patterns. Stine (2010) observed that Pennsylvania counties tend to reassess late within their mandatory cycles, influenced by economic conditions and fiscal pressures. Wealthier and rapidly growing counties postpone reassessments, while those with strong business expansion conduct them more frequently. In another study, Stine (2005) showed that counties near the legal tax rate limit are more likely to initiate reassessments, suggesting their use as an alternative to increase revenue. Eom et al. (2017) added evidence of regional diffusion and the role of institutions in determining the frequency of assessments.
The literature also demonstrates that revaluations are used strategically. Ross and Yan (2012) and Ross and Mughan (2018) documented how counties exploit the “fiscal illusion” created by increasing assessed values, which generates additional revenue even with stable or declining tax rates. This reinforces that the timing of the revaluation is a political, not just administrative, decision. However, there are still no studies investigating whether municipalities deliberately postpone revaluations during recessions, nor whether such delays strengthen fiscal health or produce adaptive behaviors after mandatory revaluations in adverse periods.
According to Afonso, the state of North Carolina offers an ideal institutional context for examining these issues. State legislation requires reassessments at least every eight years, but grants broad discretion for shorter cycles. Counties must publicly announce the planned year, and may adjust it as long as they respect the legal limit. This combination of minimal standardization and local flexibility generates significant variation in the schedules and the effective timing of reassessments, under uniform state rules.
This arrangement allows for testing different theoretical frameworks. The autonomy-effectiveness theory (Rainey & Steinbauer 1999) suggests that greater autonomy improves performance, provided it is accompanied by accountability mechanisms—precisely the balance created by the eight-year limit. Here, "effectiveness" is operationalized as fiscal health, measured by the ability to maintain stable services with sufficient and predictable revenues. The context also allows for the application of organizational adaptation theory (Hendrick 2011; Jimenez & Afonso 2022), according to which organizations develop flexible strategies to withstand fiscal shocks. Just as revenue diversification stabilizes local finances, flexible revaluation cycles can mitigate the impact of recessions on the main source of municipal revenue. The theory predicts that counties forced to revalue during recessions—when real estate values are depressed—will learn from this experience and adopt shorter cycles subsequently.
Finally, the study's hypotheses derive directly from this context. The first predicts that counties with discretionary power will postpone reassessments during recessions, especially in the years immediately following them. The second and third postulate that flexibility—and its effective use—will be associated with greater fiscal health. The fourth examines organizational adaptation, testing whether counties forced to reassess during recessions adopt shorter cycles to avoid future exposure. Together, these hypotheses transform North Carolina's reassessment policy into a natural laboratory for understanding how local governments strategically manage their primary source of revenue.
- Evaluation Details
This study adopts a multi-method approach using data from all 100 counties in North Carolina over twenty years (2000–2019). Information on property tax reassessments comes from the state Department of Revenue, while the other variables are obtained from the Office of Budget and Management. The analytical strategy combines three techniques: (i) logistic regression to analyze decisions about the timing of reassessment; (ii) propensity score matching to compare counties that delayed reassessment with those that did not; and (iii) propensity score-adjusted regression to estimate impacts on fiscal health. This triangulation reinforces causal inference while acknowledging the observational nature of the data.
North Carolina provides an ideal scenario because it mandates reassessments at least every eight years, but allows counties to adopt shorter cycles, creating situations of both mandatory and optional reassessment. Property tax accounts for approximately 25% of total county funding and half of own revenues, making the timing of reassessment fiscally relevant. Because values are set on January 1st, decisions and administrative work occur in the preceding year; therefore, the study analyzes reassessment years with a time lag (e.g., the 2008 fiscal year reassessment is treated as 2007). Assessors are appointed by county commissioners, and decisions involve assessers, boards, and administrators.
The study examines two recessions: the dot-com bubble burst (2001) and the Great Recession (2007–2009). During the formal recession years, 65 reassessments occurred, of which 36 were optional; only two counties with discretion postponed the reassessment, indicating a lack of strategic postponement in those years. The pattern changes in the post-recession periods (2002–2004 and 2010–2013): of the 115 reassessments conducted, 62 were optional and 57 were postponed—44 after the Great Recession and 13 after the dot-com bubble burst. Almost half of the counties with optional reassessments in these periods opted for postponement, a behavior that was much more intense after the 2007–2009 housing crisis.
Finally, the study uses Zillow's real estate valuation data, which captures market variations in real time, to demonstrate the lag between economic conditions and property values. Although more representative of populous counties, this data shows that value declines were greater in post-recession periods than during recessions—a pattern observed across all quartiles, especially among higher-value properties. This lag explains why strategic deferral occurs after, and not during, recessions: it is in the subsequent period that depressed values materialize, reducing the tax base if revaluation is carried out. The severity of the Great Recession generated substantially larger deferrals than the 2001 recession, reflecting the magnitude of the shocks to the housing market.
- Method
To test whether counties strategically postpone reassessments during recessionary periods (H1a and H1b), the study uses logistic regression with fixed effects. The model estimates the probability of a county postponing its scheduled reassessment in a specific year, incorporating county fixed effects—which control for unobserved and time-invariant characteristics—and year fixed effects, which capture shocks common to all counties. The main independent variables represent economic conditions through two specifications: a single indicator for any recessionary period (official recessions and subsequent years) and separate indicators for recessions defined by the NBER and their after-effects. The model also controls for the time remaining until the statutory reassessment deadline and includes a comprehensive set of socioeconomic and fiscal variables, such as changes in property tax rates, population dynamics, party affiliation, property valuation, per capita spending, unemployment, median income, and demographic composition.
The sample is restricted to the 69 counties (861 observations) that had a scheduled reassessment and the discretion to postpone it. Counties with fixed eight-year cycles or no scheduled reassessment are excluded. After completing a reassessment, the county leaves the sample, ensuring that the model captures only the active decision window.
The second stage assesses whether revaluation flexibility and effective deferral decisions influence fiscal health (H2 and H3). Fiscal health is measured by two variables: the operating ratio—general fund revenues divided by expenses—which reflects annual and structural solvency; and the total property valuation, which represents the tax base directly affected by revaluations. The study employs two-way fixed-effects models. To test H2, a flexibility indicator (fixed eight-year cycle versus shorter cycles) is included, in addition to interactions with recessionary periods. For H3, the main variable is the effective deferral decision, analyzed in three subsamples: all counties, counties that deferred versus counties without flexibility, and counties that deferred versus counties with flexibility that chose not to defer. This approach distinguishes the effects of discretion from the effects of the deferral itself.
As robustness tests, the study applies propensity score matching and propensity score-adjusted regression, creating comparable groups of counties that did and did not postpone reassessment, reducing selection biases and approximating experimental conditions.
The final stage tests the organizational adaptation hypothesis (H4): whether counties required to reassess during recessions—when property values were temporarily depressed—later adopt shorter cycles, preserving future flexibility and correcting reduced valuations more quickly. The analysis focuses on the 82 counties that faced mandatory revaluations during recessionary periods, comparing their subsequent cycle length choices with counties that revalued during non-recessionary periods. A fixed-effects logit model is used, in which the dependent variable indicates the adoption of a cycle shorter than eight years, and the main independent variable identifies whether the previous mandatory revaluation occurred during a recession. Socioeconomic controls, recession indicators, and county and year fixed effects are included, with propensity score methods providing alternative specifications to mitigate potential confounding factors.
- Main results
Afonso reiterates that logit models with fixed effects show robust evidence that North Carolina counties strategically postpone property tax reassessments, but only during periods of "recession effects"—the years immediately following recessions—and not during official recessions. Counties with scheduled reassessments in these post-recession years are 2,06 times more likely to postpone them than in normal periods, a statistically significant and substantial effect. The absence of postponement during recessions is consistent with administrative lag: reassessments need to be completed by January 1st, and property values only fully decline after some time. The fact that the postponement occurs primarily after the Great Recession, and not after the milder recession of 2001, suggests that the central motivation is to avoid reassessing properties at temporarily depressed values, and not to save administrative costs.
According to Afonso, some results from the control variables are also relevant. The probability of postponement increases as the scheduled year approaches, indicating that counties are awaiting more complete information before deciding. Increases in property tax rates reduce the probability of postponement, consistent with the use of reassessment as a revenue-raising alternative when raising rates is politically difficult. Counties with rates above the state average are more likely to postpone, possibly because they face greater resistance to further increases if reassessment reduces the tax base.
Additionally, the results regarding the effects of flexibility and deferral on fiscal health (H2 and H3) are modest and heterogeneous. Fixed-effects OLS models show no significant relationship between operating on a mandatory eight-year cycle and the operating index or property valuation. However, counties required to reassess during recessions show significantly lower property valuations than those with shorter cycles, indicating a fiscal cost associated with mandatory revaluation during adverse periods. The actual decision to defer is associated with higher valuations, both compared to mandatory revaluations and optional revaluations conducted according to schedule. There are no consistent effects on the operating index. Propensity score methods offer only partial support, suggesting that the benefits of deferral are context-dependent and not universal.
Finally, the study finds no evidence of organizational adaptation (H4). Counties forced to reassess during recessions do not demonstrate a greater likelihood of adopting shorter cycles subsequently. This result holds true both with the aggregate measure of recession and with separate indicators of recession and recession effect. Although population and per capita spending increase the likelihood of shorter cycles, the experience of reassessing under unfavorable economic conditions does not alter future behavior. Surprisingly, propensity score methods suggest that counties that were forced to reassess outside of recessions are more likely to shorten subsequent cycles, directly contradicting the adaptation hypothesis. Thus, there is no evidence that municipalities learn from adverse reassessment experiences to increase their future flexibility.
- Lessons in Public Policy
The main policy lesson of the study is that discretionary authority for revaluation—limited autonomy within a maximum range defined by the state—functions as a valuable fiscal infrastructure for local governments. Municipalities that adopt shorter cycles retain the option to postpone revaluation when economic conditions demand it, and those that exercise this option in the post-recession period achieve slightly higher property valuations than counties forced to revalue during unfavorable times. The fact that postponement occurs almost exclusively after severe recessions, motivated by concern for temporarily depressed values and not by administrative economy, indicates prudent, not opportunistic, use of discretion. Thus, for the 24 states that impose maximum limits but allow local flexibility, the point is not that short cycles are always better, but that the combination of shorter planned cycles and the possibility of postponement offers the ideal balance. The nine states with mandatory annual reassessments and the eighteen with rigid four-year cycles may inadvertently compromise fiscal resilience by eliminating this countercyclical tool.
The study also questions the political consensus that favors frequent and mandatory reassessments as a solution to tax inequalities. Although technical recommendations—such as those from the International Association of Appraisal Officials—advocate three- to five-year cycles to reduce dispersion and horizontal inequality, and although cases like Delaware show the risks of long delays, the results indicate that rigid mandates have fiscal costs. Counties required to reassess during recessions suffer statistically significant drops in property valuations, putting pressure on revenues and potentially requiring service cuts or politically difficult rate increases. The challenge, therefore, is not to choose between equity and resilience, but to balance both. The North Carolina model—an eight-year cap with broad discretion to shorten or postpone—offers a plausible balance. States with short mandatory cycles could relax their caps, while states without discretion could introduce limited autonomy that reconciles equity and fiscal stability.
A worrying finding is the lack of organizational adaptation. Municipalities forced to reassess during recessions do not subsequently adopt shorter cycles to protect themselves from future crises. This lack of institutional learning suggests that adverse fiscal experiences do not, in themselves, generate proactive changes. Thus, state policymakers cannot assume local self-correction; follow-up mechanisms, technical assistance demonstrating the benefits of flexibility, or incentives for adopting shorter cycles may be necessary. The fact that larger counties with higher per capita spending are more likely to shorten cycles indicates that administrative capacity and fiscal slack are prerequisites for adaptation, reinforcing the importance of investments in local capacity.
Finally, the study offers empirical support for Rainey and Steinbauer's autonomy-effectiveness theory in the context of property tax. Counties with significant, yet limited, discretion outperform those subject to rigid mandates—and presumably, those with unrestricted autonomy as well. This suggests that state policies in areas such as zoning, public health, or emergency management should seek similar arrangements: clear boundaries that ensure accountability, combined with substantial discretion within those boundaries and deference to local knowledge regarding timing and implementation. In the specific case of property tax, the ideal policy involves state-defined maximum ranges, long enough to allow for strategic deferral, accompanied by minimum standards that prevent long delays and technical support that allows counties to exercise their discretion effectively.
