Why your BC assessment doesn't match your market value

It is common to look at a BC assessment and feel it does not match what the property is worth today, higher in a falling market, lower in a rising one. Usually that is not an error. It is the calendar. BC assessments are tied to specific dates, and once you understand those dates, most of the mismatch explains itself, and the cases that are genuinely appealable become easier to spot.

Why doesn’t my assessment match today’s market?

Because your assessment is not meant to reflect today. BC Assessment values every property as of July 1 of the prior year, and considers its physical condition as of October 31. So a notice that arrives in January 2027 reflects what the property was worth on July 1, 2026, in the condition it was in on October 31, 2026, not its value the day you open the envelope.

The Province sets both dates in law. BC Assessment estimates market value as of July 1 and considers physical condition and permitted use as of October 31 each year. The July 1 date fixes the market moment everyone is measured against, so every property in the province is valued on the same footing. The October 31 date captures new construction, renovations, damage or a change in permitted use. A building half-finished on October 31 is assessed as half-finished, even if it is complete by the time the notice lands.

This is why a mismatch with today’s market is normal rather than suspicious. If prices have moved since last July, your assessment will naturally look out of step. The question that matters for an appeal is not whether the value matches today, but whether it was correct on July 1 of the prior year.

What happens to my assessment in a rising market? A falling one?

The assessment lags in both directions. In a rising market, your assessment reflects a July 1 value that is now several months old, so it can look low compared with current prices. In a falling market, the same lag works the other way: the assessment can look high because it captured a peak that has since passed. Neither lag is a mistake.

In a rising market, a lower-looking assessment is not something to correct. It simply means values climbed after the valuation date, and the next roll will catch up. In a falling market, an assessment that feels too high is the more frustrating case, and it is the one owners most want to appeal. But the test is still July 1. If comparable sales and market evidence show the property really was worth less on July 1 than BC Assessment concluded, there is a case. If the value was fair on July 1 and only the market that followed turned down, the decline belongs to the next assessment, not this one. For commercial owners, the same logic applies to income: what mattered on July 1 was the rent, vacancy and capitalization rate the market supported then, which our guide on how BC Assessment values commercial property covers in detail.

When is a mismatch appealable, and when isn’t it?

A mismatch is appealable when you can show the July 1 value was wrong; it is not appealable simply because the number went up or feels high. The size of an increase is not a foundation for a complaint on its own. What carries weight is evidence that the assessed value does not match what the property was worth on the valuation date.

Two kinds of evidence do that work. The first is market evidence: comparable sales around July 1 that point to a lower value than BC Assessment assigned, or, for commercial property, actual rents, vacancy and income that do not support the assumptions behind the assessment. The second is equity: comparable properties assessed lower than yours without a defensible reason. BC assessments are supposed to be fair relative to similar properties, so a genuine inequity is a legitimate ground.

It is worth being honest about what does not qualify. A jump that simply tracks the market, an assessment that looks high only because prices fell after July 1, or a gut feeling that the number is too big without supporting evidence, none of these is a strong appeal. And appealing carries a real risk worth naming: a review panel looks at the whole assessment, so a property that is actually under-assessed can have its value confirmed or raised. Our guide on whether you should appeal works through that decision in full, and what a jumped assessment actually means explains why a higher value does not automatically raise your taxes.

How do you check what your assessment should have been?

Start by anchoring on July 1. Look for what comparable properties were selling for around that date, and how similar properties were assessed. The goal is a defensible answer to one question: what was this property worth on July 1 of the prior year? That is the number BC Assessment was trying to reach, and the number an appeal argues about.

For a home, that usually means comparable sales near the valuation date and a scan of how neighbouring, similar properties were assessed. For commercial property, it means the income the building could reasonably earn, actual rents, realistic vacancy and a market capitalization rate, set against BC Assessment’s assumptions, plus comparable assessments for the equity check. If those point clearly below the assessed value, you likely have a case. If they land in the same range, the assessment is probably fair, and the honest move is to leave it. When the numbers do support a challenge, the deadline is fixed: a Notice of Complaint must be filed by January 31, as our guides on how to appeal your BC Assessment and appeal deadlines explain.

One caution about the equity check: it cuts both ways. Comparable properties assessed lower than yours can point to a genuine inequity, but small differences often reflect real differences in size, age, condition or exact location, so a single lower neighbour is a reason to look closer, not proof of an error. And because a review panel can adjust a value in either direction, the honest test before filing is not just whether some comparables are lower, but whether the weight of the July 1 evidence, sales, income and assessments together, says the value should come down. If it does, you have a case worth making; if it does not, leaving the assessment alone is the better decision.

How do you research the July 1 value?

The free BC Assessment search is the natural starting point. You can look up any property in the province by address, roll number, or PID, and a free account lets you save properties and compare several assessments side by side. The goal is not just to see your own value but to build a small set of genuine comparables: similar properties, in the same class, that anchor what the July 1 value should have been.

Because the standard is market value on July 1 of the prior year, the most useful sales are ones that closed around that date. A sale from six months after the valuation date, in a market that has since moved, tells you less than a sale near July 1 of a truly comparable property. When you compare assessments rather than sales, hold the important variables constant, size, age, class, and location, so a lower neighbour reflects a real difference in value rather than a real difference in the building. A consistent pattern across several close comparables is far stronger evidence than a single low number.

Keep the physical condition date in view as well. BC Assessment fixes condition and permitted use as of October 31, so if your property lost value between July 1 and October 31, through damage or a change in use, that belongs in this year’s assessment. Work or improvements finished after October 31 do not, and neither does a market decline that arrived after July 1. Sorting what falls inside the year from what falls into the next one is often the difference between a case that holds and one that does not.

What if the July 1 value really was too high?

If your research points clearly below the assessed value, the first step is to raise it with BC Assessment directly. Many genuine mismatches, a wrong class, an overstated size, a clear factual error, get corrected in a conversation without any formal process. When that does not resolve it, the first level of appeal is a free complaint to the Property Assessment Review Panel, filed with BC Assessment by January 31. The panel gives each complaint a short hearing, by phone or in writing, between early February and the middle of March.

If the panel decision still does not reflect the July 1 value, there is a second level: an appeal to the Property Assessment Appeal Board by April 30. That step carries a per-folio filing fee and requires that you went through the review panel first, so it is a genuine escalation rather than a starting point. Our guide on PARP vs PAAB compares the two levels, and appeal deadlines sets out the full calendar so nothing lapses.
