Compliance, equity, and rate classification aren't three separate consulting projects. They're three dimensions of the same problem — and findings from each one inform the others. Together they produce something no single product delivers alone: a complete picture of where your municipality is losing ground, and a documented path to recovering it.
You don't need to start with all three. But understanding how they interact changes how you think about which one to start with.
Models every permissible configuration across all five property classes — residential, commercial, industrial, open space, and personal property — independently and in interaction. Produces a board-ready recommendation and hearing presentation.
What it reveals about the other two: A properly structured personal property class rate — informed by what the compliance review found — can recover revenue that compliance gaps have been silently forfeiting. The rate classification and compliance products together close the same problem from two directions.
Explore → Rate ClassificationIdentifies non-resident property owners who are underpaying or not paying personal property, and applicable excise obligations taxes. Produces named, ready-to-act deliverables: demand packages, evidence files, inquiry lists, enforcement toolkit.
What it reveals about the other two: The personal property compliance gap tells you something about your assessed valuation picture. Undervaluers identified here often appear in the equity analysis as well — properties where the declared personal property value and the assessed real property value are simultaneously inconsistent.
Explore → Compliance ReviewCalculates assessment ratios by value tier and neighborhood using the IAAO framework. Identifies systematic patterns — over-assessment of modest homes, under-assessment of high-value properties — before they become an abatement wave or DOR compliance problem.
What it reveals about the other two: The equity analysis identifies which property classes are carrying a disproportionate share of the burden — which informs the rate classification analysis directly. If high-value residential is systematically under-assessed, a classification rate change may protect the wrong taxpayers unless the equity picture is understood first.
Explore → Equity AnalysisEach product produces findings that are useful on their own. But the intersections — where two products illuminate the same problem from different angles — are where the most significant findings live.
The compliance review identifies non-resident personal property non-payers and undervaluers. The rate classification analysis models personal property as an independent class with its own rate potential.
A community that pursues both simultaneously can recover compliance revenue through demand letters and structure the personal property rate to maximize the value of newly registered accounts going forward. The compliance findings become the baseline for a better-structured personal property rate.
Rate classification can protect residential taxpayers — but "residential" is not a homogeneous category. If the equity analysis reveals that lower-value homes are over-assessed and high-value properties are under-assessed, a blanket residential factor reduction primarily benefits the taxpayers who are already under-assessed.
The equity analysis tells you who within the residential class actually needs protection. The classification analysis tells you how much structural relief is available. Together, they produce a rate recommendation that is both analytically sound and defensible to the residents who ask why their bills aren't going down.
Undervaluers identified in the compliance review — non-resident owners declaring $800 in personal property for a $3M seasonal estate — often turn out to be the same properties that are under-assessed in the equity analysis. The estate that's paying too little personal property tax is frequently also assessed below its true market value.
These are not coincidental. High-value properties have more leverage to push back on assessments and more incentive to minimize their declared personal property. The compliance and equity analyses surface the same problem through different data — and together make a much stronger case for assessor action than either does alone.
A community of 3,500 parcels with significant seasonal ownership, softening commercial values, post-pandemic residential appreciation, and a governing body that has raised the residential rate three years running.
The Scenario Matrix shows that splitting commercial and industrial rates — setting industrial at 1.45× residential while holding commercial at 1.20× — combined with a residential factor of 0.88 produces $680 annual relief for the median homeowner on a $400,000 assessed home, while keeping commercial rates competitive with neighboring communities. Personal property classified separately at industrial rate level.
Cross-referencing the voter rolls against the assessor's database and PPT commitment list surfaces 340 non-resident-owned properties with no Form of List on file. Undervaluation analysis identifies 45 statistical outliers with publicly documented evidence. Applicable excise gap analysis — scoped to this community's profile — surfaces additional accounts for structured assessor follow-up.
The Ratio Report shows a community-wide COD of 17% — above the IAAO standard — with the highest ratios concentrated in lower-value residential tiers. The Heat Map shows two neighborhoods where assessment ratios average 22% above the community median. Industrial property ratios run 18% below median. The Abatement Watch List flags 28 properties for pre-revaluation review.
The first year establishes your baseline across all three products. Each annual review builds on it — tracking new non-compliance as ownership changes, monitoring assessment ratios as markets move, and updating the rate classification model as your valuation composition evolves.
A community that runs all three products annually doesn't need to react to abatement waves, compliance gaps, or rate-setting pressure. It stays ahead of all three simultaneously.
The data infrastructure is built once. The annual review uses it across all three products. The marginal cost of each subsequent year is a fraction of the first — which is why the annual review is where the return on the initial investment is realized.
Full data infrastructure built. All three analyses run. ROA delivered first, then named deliverables in sequence. Compliance demand letters sent. Classification hearing supported. Equity drift quantified and corrected.
New non-resident property purchases appear. First-year demand letter responses processed. Updated equity ratios reflect market movement. Classification matrix updated for current valuation composition.
Two years of equity data inform the next certification cycle. Compliance database is mature — focus shifts to net-new non-filers and updated undervaluation cases. Classification recommendation incorporates three years of trend.
The compliance gap doesn't re-accumulate. Assessment equity is monitored continuously. Rate structure is optimized annually. The governing body makes one decision each budget cycle — sustained by ongoing analysis.
The three products share the same data infrastructure. Start with whichever question is most urgent. Add products as the engagement develops — the incremental cost of each additional product is substantially lower than starting fresh.
Start with Rate Classification. The scenario matrix is the most time-sensitive product — if your hearing is approaching, this is where to focus. Compliance and Equity follow in the next cycle.
Start with Compliance Review. The Revenue Opportunity Assessment quantifies the probable gap and makes the internal business case for adding Classification and Equity later.
Start with Assessment Equity. The Abatement Watch List and DOR Compliance Memo address the most immediate legal risk. Compliance and Classification follow naturally once the equity picture is clear.
In every case, the Revenue Opportunity Assessment — the first deliverable in any engagement — will clarify which entry point makes the most sense for your specific community. You don't need to decide before we talk.
Start the ConversationWe'll talk through your community's budget situation, which questions are most urgent, and what a phased or comprehensive engagement looks like. No data required on your end to start. Legal and methodological briefing for your governing body or city/town counsel available at no charge.
