Data Center Property Tax Abatement: How to Look Up What a Named Facility Actually Got

How to find a specific data center's property tax abatement — the bond validation order, the development authority, the shell LLC. Georgia's own auditors priced the average abatement at 17.3% of the bill, and in Northern Virginia there is no abatement at all: there is a separate rate class that has gone up seven years running.

People arrive at this page having searched for a building by name. Not "data center tax incentives" — something much more specific, like what tax break did this particular facility get. The three most common shapes of that question are a brand, a code and a town: an operator's name, the facility's own designator, and where it sits.

That is the right question. It is also the one the public record is worst at answering, and the reason is worth understanding before you start looking: the abatement is almost never filed under the name on the building.

This page is about how to find it anyway, what it is typically worth, and the two states where the answer is the opposite of what the phrase "property tax abatement" suggests.

Why the facility's name is not what the record is filed under

Sales tax exemptions are state programmes with published rules — that is why we could work through six states one at a time. Property tax abatements are not like that. They are negotiated one deal at a time, by a local authority, and they are usually implemented through a financing structure rather than a tax form.

Georgia's state auditors, evaluating the state's own exemption, put the problem plainly:

"Reliable data on local abatements can be rather difficult to obtain and even more difficult to analyze due to the wide variation in types of abatement agreements."

They went on to describe who decides: "At the local level, counties and development authorities play the decisive role in negotiating property tax abatements, PILOTs, and other discretionary incentives for specific projects. This local discretion means the fiscal tradeoffs and revenue impacts vary substantially across jurisdictions." (Georgia Department of Audits and Accounts, *Tax Incentive Evaluation: Georgia Data Center Sales & Use Tax Exemption*).

So there are three names in play for any one building, and only one of them is the one you searched for:

The entity on the abatement agreement is typically a single-purpose LLC formed for that project. The abatement itself typically lives in a bond validation order in a county court file.

The structure to look for: bonds for title

Across Georgia and much of the South, a local property tax abatement is delivered as a sale-leaseback through a development authority — commonly called a bonds-for-title deal. The mechanics, in order:

1. The county or joint development authority issues revenue bonds.
2. The authority takes legal title to the project — land, buildings, and often the equipment.
3. The authority leases it back to the company, which makes payments that service the bonds.
4. Because title sits with a public authority, the property is exempt or partly exempt from ad valorem tax for the term; the company instead makes payments in lieu of taxes, or pays on a rising fraction of value.
5. At the end of the term the company takes title for a nominal sum.

This is why there is no "abatement certificate" to look up. The abatement is a consequence of who holds title, and the document that creates it is a bond resolution plus a lease.

It is also why these deals surface publicly at one specific moment: Georgia requires bonds to be validated by a superior court, which puts the amount, the authority and the structure into a court record.

How to look up one named facility, in order

This is the procedure. It works because it goes from the one reliable key — the address — outward.

1. Get the street address, not the facility code. Operators publish addresses on their own location pages because customers need them.
2. Find the county, then the parcel. The county tax assessor's property search, keyed on the address, gives the parcel number, the current owner of record and the assessed value. If the owner of record is a development authority, you have just found an active bonds-for-title abatement without reading a single document.
3. Search the development authority's minutes and resolutions for the parcel or the LLC name the assessor gave you. Authorities are public bodies and post agendas.
4. Search the county superior court (or your state's equivalent) for the bond validation.
5. Read the assessed value history on the parcel. An abatement shows up as a taxable value far below the market value, or as a taxable value that steps up on a schedule.

Step 2 is the one most people skip, and it is the one that usually ends the search. The owner-of-record field is a public, single-field answer to "is this facility abated".

In Georgia, steps 2 and 4 have a statewide shortcut worth knowing: the Georgia Superior Court Clerks' Cooperative Authority runs a single index covering all counties, with a Real Estate Deed Index, a Lien Index, a Plat Index and a PT-61 (transfer tax) index (search.gsccca.org). A transfer of title to a development authority is a deed, so it appears there. Some of its searches are marked PREMIUM; we did not test which run without an account, so treat access as an open question rather than assuming it is free.

We ran this procedure on three real facilities, and here is how far we got

Being specific about where a method stops is more useful than a method that is only described. We took the three facility-level searches readers most often arrive on — an operator plus a market code plus a town — and tried to complete the lookup on 5 November 2026.

We did not finish any of them. Three different things went wrong, and each one is a thing you should expect:

• The assessor's parcel search would not open from our machine. Georgia county assessor and public-access property portals returned HTTP 403 or failed to connect. These are the free public records at the centre of step 2, and they are often behind bot protection that treats a script like a threat. A browser on a residential connection is a different experience from ours; we report what we actually got.
• The county itself was in dispute. For one facility, commercial data center directories disagreed about which county the building is in — and the county is what determines the authority, the mill rate and the court. Two commercial sources naming different counties for one address is a reminder that these directories are not records.
• No abatement document surfaced for any of the three. Not "we found a record showing no abatement" — nothing either way.

What an abatement is actually worth, with the arithmetic

Here the Georgia evaluation is unusually useful, because its authors did the thing we cannot: they obtained the agreements.

They got data on four large data center projects across the metro Atlanta area — nine individual buildings, $6.5 billion of investment. Then, "[i]n order to avoid publication of individual project level data", they combined them into one "representative" complex.

That sentence deserves a moment, because it is the direct answer to the question that brought you here. The state's own researchers held the named-facility data and deliberately did not publish it. If you are looking for one building's number and not finding it, you are not searching badly.

What they did publish is the shape of the bill:

And the bill itself: the average combined local mill rate in the sample was 3.68%, property is taxed on 40% of fair market value, so the complex "would owe $33.6 million in local property taxes in a given year". The average annual abatement was 17.3% of calculated property tax at the prevailing mill rate, leaving the jurisdiction "collecting $27.8 million in property tax after accounting for the abatement" (same source). The abated amount is therefore about $5.8 million a year.

Two things follow, and both matter more than the headline.

First: 17.3% is not 100%. The way these deals are discussed — "a huge tax break", "decades of abatement" — invites the assumption that an abated data center pays little. In this sample it paid 83% of the calculated bill. If a projection carries a property tax line near zero for the abatement years, it is not describing the average Georgia deal. Ask for the schedule.

Second: the servers are the tax base. About 79% of the taxable value is equipment, not real estate. That single fact reorganises how to read a data center's property tax exposure:

• The bill tracks the refresh cycle, not the building. Equipment is revalued as it is installed, depreciated and replaced.
• An abatement limited to real property touches about a fifth of the value. Whether equipment is included is the most important term in the agreement, and the easiest one to leave vague in a summary.
• It is why the states that tax this well do it through a separate class for computer equipment — which brings us to the two counties where the whole premise of this page inverts.

Northern Virginia: there is no abatement. There is a rate class, and it keeps rising

If you search for a Loudoun or Prince William facility's property tax abatement, you will not find one, because that is not how those counties treat data centers. They treat them as a named classification of business personal property, taxed at a rate the board sets each year.

Loudoun County's published business tax rates list, line by line:

• "Business Equipment": $4.15 per $100 of assessed value
• "Computer Equipment in a Data Center": $4.15
• "Machinery and Tools as Defined in Va. Code Sec 58.1-3507": $2.75
• "Wireless Broadband Equipment": $2.10

(Loudoun County, Business Tax Rates). The county states that this rate, which "applies to property in data centers, remains the same as the current rate for tax years 2026 and 2027: $4.15 per $100 in assessed value" (Loudoun County, Data Centers: Tax Revenues & County Budget).

Prince William County's tax year 2026 rates set "Computer equipment and peripherals used in a data center" at $4.50 per $100 of assessed value — the same as its "General classification of tangible personal property", against a real estate base rate of $0.865 (Prince William County, Tax Rates).

Read those two tables together and the design is clear. The data center rate is not a discount; in both counties it equals the ordinary business equipment rate. What the separate line does is make the class independently adjustable — and Prince William has adjusted it.

Seven increases in seven years

S&P Global Ratings, in a report published 28 October 2026 and hosted on the county's own site, describes the fiscal 2027 budget:

"The budget increases personal property tax on computer equipment and peripherals to $4.50 per $100 assessed valuation (AV), an increase from $4.15 in fiscal 2026 and the seventh annual tax rate increase since $1.25 in 2019."

(S&P Global Ratings, *Prince William County, VA Series 2026 Special Obligation School Financing Bonds Rated 'AAA'*, 28 October 2026).

From $1.25 to $4.50 is 3.6× in seven years, on the line item that is about 79% of a data center's taxable value. No abatement expired. No agreement was breached. The rate simply went up, every year, by vote.

This is the single most under-modelled risk on this page. A ten-year projection that holds the local property tax rate flat is not being conservative; in this county it would have been wrong seven times running. The question for a sponsor is not "do we have an abatement" but "what rate does the model assume in year seven, and what has this jurisdiction's rate done for the last seven?"

The same report records the county's own view of why it can keep going: "Management states that the taxes are a relatively small portion of a data center's operating costs and has not observed reduced demand for data center construction or operation as the result of tax increases."

It also names the volatility that cuts the other way, and it is the mirror of the 79% finding: "Changes to chip valuations, reduced hardware refreshes, scaled back operations, or chip supply constraints could all lead to volatile" assessed value. A tax base made of servers moves with the price and pace of servers.

Why the rate goes up: it is paying for the homeowner's rate going down

Both counties say this themselves, which makes the political mechanism unusually easy to verify.

Prince William's board, adopting the FY2027 budget on 21 April 2026, in one action "adjusted the personal property computer equipment and peripherals tax rate from $4.15 to $4.50 per $100 valuation" and "reduced the real estate tax rate from $0.906 to $0.865 per $100 of assessed value" — a cut the county says lowers the average residential bill by $56 (Prince William County news release, 22 April 2026).

Loudoun describes the same trade: data center revenue has allowed the board to "generally lower the real property tax rate for homeowners every year for the past decade", and to eliminate the "$25 vehicle license fee" (Loudoun County, same page as above).

So the data center rate is the adjustable side of a deliberate exchange. For an investor that converts a tax line into a political variable with a direction: it rises when residential rates need to fall, and residential rates usually need to fall.

Named reversals: the direction of travel is not toward more abatement

Two 2026 actions, both from official sources, show which way local sentiment is moving.

Fulton County, Georgia — 5 August 2026. The Board of Commissioners approved a resolution "opposing tax abatements or other financial incentives from any development authority within Fulton County" for data center projects, and "urging the Development Authority of Fulton County (DAFC) to decline consideration of such incentives", citing "significant and increasing public concerns about data centers' water and power use, noise and traffic" (Fulton County).

The detail that matters for diligence is in the same notice: the DAFC operates independently of Fulton County government. The commission's resolution therefore urges; it does not bind the body that actually grants abatements. A project in Fulton is neither safe because the authority is independent nor dead because the commission objects — which is precisely the kind of question to settle with a document rather than a headline.

Prince William County, Virginia. The S&P report records that "[l]ast month, the county eliminated by-right data center development and proposed data centers to now require special use permits", and that the county has "59 completed data center buildings", "29 buildings under construction", and "53 planned buildings that have received land use approvals". It then adds a sentence any investor in an approved-but-unbuilt project should read twice: "it is unclear whether the county would have legal authority to prevent these projects from proceeding in the future."

An entitlement is not a right until someone decides it is.

Two states where taking the sales tax exemption costs you the abatement

The property tax question is not separable from the sales tax question, because in two of the six states we have examined they are explicitly linked.

Michigan makes them mutually exclusive by default. An enterprise data center must show it "does not receive and, through the applicable date, will not receive any state or local property tax benefit" — defined to include "property tax exemptions, millage rate or valuation reductions, and property tax capture". There is one way through, and it is political: the bar "does not apply if the governing body of each local unit of government affected by the property tax benefit approves the receipt of the property tax benefit by resolution" (worked through here). Every affected city, village, township and county.

So a Michigan model carrying both benefits is carrying an assumption about several councils' votes. Ask for the resolutions, by name and date.

Michigan's repayment provision reaches further than most, and it reaches the property tax question too: on revocation the certificate holder repays the exemptions received "by all persons" — its own, its affiliates' and its construction contractors' — "plus interest".

Texas does a narrower version. Its sales tax exemption excludes a data center holding certain appraised-value limitation agreements under Tax Code Chapter 313, so those two particular incentives do not stack (worked through here).

Ohio's proposed H.B. 646 would cap local property tax abatements at 50% of improved value — not law, but the direction (discussed here).

The general lesson is the one the stacking rules make concrete: a projection that adds up every incentive it can name has probably added two that cannot be held at once.

Eight checks on a property tax abatement

1. Who is the owner of record on the parcel? If it is a development authority, there is a bonds-for-title abatement in place. This is a free, one-field check and it should be the first thing you do.
2. What entity is the counterparty — and is it the sponsor, the parent, or a single-purpose LLC with no other assets?
3. Does the abatement cover equipment, or only real property? About 79% of the taxable value is equipment. An abatement on the building alone is worth roughly a fifth of what it sounds like.
4. What is the schedule, and what is the percentage? Georgia's sampled average was 17.3% of the calculated bill, not 100%. Ask for the step-up table year by year.
5. What rate does the model assume, and in which years? Then look up what that jurisdiction's rate has done for the last five years. In Prince William it rose every year since 2019.
6. What happens at expiry? The abatement years are the years the projection shows. Model the first full-rate year.
7. Is a sales tax exemption also assumed? In Michigan the two are mutually exclusive without a resolution from every affected council; in Texas, certain Chapter 313 agreements disqualify the exemption.
8. Is the entitlement final? By-right development is being withdrawn in some jurisdictions, and an approval that has not been built on is a weaker thing than it looks.

The full diligence list is in questions to ask a sponsor, and the per-state sales tax treatment is in data center tax incentives, with the six states side by side.

Whether any of this reaches you depends on the lease: if property taxes are passed through to the tenant, the abatement is the tenant's benefit and the expiry is the tenant's problem — until renewal. What a hyperscaler lease contains is where that is decided.
