What Is Inventory Tax? Which States Tax Business Inventory

What is inventory tax? Inventory tax is a property tax on the value of goods a business holds in stock — raw materials, work in progress, and finished goods. It is levied by state and local governments in a minority of US states as part of tangible personal property (TPP) tax. How is inventory taxed? According to Tax Foundation analysis (last updated April 2025), nine US states fully tax business inventory (Arkansas, Kentucky, Louisiana, Maryland, Mississippi, Oklahoma, Texas, Virginia, West Virginia) and five partially (Alaska, Georgia, Massachusetts, Michigan, Vermont). The tax is typically assessed on a specific date (usually January 1) on the value of stock held then (Mississippi may use a 12-month average), and charged whether or not the business is profitable.

There is no federal inventory tax; it does not apply in most states. But where it does apply, it lands hardest on distributors, importers, and businesses holding large safety stock, because the tax is based on inventory value rather than profit. For businesses choosing between states for a warehouse location, this is one of the few tax differences that can genuinely change the answer.

The rest of this guide explains how the tax works, which states levy it, the freeport exemptions and foreign-trade zone relief that can remove it where available, and a state-by-state table with assessment dates and filing requirements. Start with the broader state comparison framework and port and inland hub guide, then come back here for the inventory-specific detail. For region-specific context, see our ports directory (including Port Houston and Port of Savannah) and state pages, including Texas, California, Georgia, New Jersey, and Illinois.

How inventory tax works

There is no federal inventory tax. What people call inventory tax is a component of tangible personal property (TPP) tax — a property tax levied by state and local governments on business-owned movable property. Where inventory is included in the TPP base, your raw materials, work in progress, and finished goods are assessed and taxed like any other property.

Three structural points matter more than the headline:

It is usually a local tax. Assessment and collection generally happen at county or municipal level, and rates are set locally. That means the state-level answer is only the first half — two counties in the same state can produce materially different bills. It also means you cannot finish this analysis from a national map.

It is taxpayer-active. You self-assess and file. The compliance obligation is yours, and it recurs annually. This is an administrative cost even where the tax itself is small.

It is charged whether or not you make money. Inventory taxes are levied regardless of profitability, and they fall disproportionately on businesses with larger inventories — retailers, wholesalers, and manufacturers. A loss-making year does not reduce the bill.

Which states tax inventory

According to Tax Foundation analysis, nine states fully tax business inventory:

Arkansas · Kentucky · Louisiana · Maryland · Mississippi · Oklahoma · Texas · Virginia · West Virginia

And five states partially tax it:

Alaska · Georgia · Massachusetts · Michigan · Vermont

Everywhere else, inventory is broadly outside the property tax base — though many of those states still tax other tangible personal property such as machinery, equipment, and fixtures, which matters if you are installing racking and material handling equipment. For a worked example of a statewide inventory exemption, see the California state page. For Georgia's combination of state exemption and local freeport options, see the Georgia state page. For New Jersey's limited approach to business personal property taxation, see the New Jersey state page. For Illinois, where only real property is taxed, see the Illinois state page. For Pennsylvania, where business inventories are not taxed, see the Pennsylvania state page.

Treat this list as a starting point with a date on it, not a current legal position. It reflects Tax Foundation's published state-by-state analysis, and this area moves: states have been reforming TPP taxes steadily, generally in the direction of narrowing them. Georgia's de minimis TPP exemption rose from $7,500 to $20,000 on 1 January 2025. Texas exempts up to $125,000 of income-producing tangible personal property per location per taxing unit as of 2026. Vermont has been phasing inventory taxation out at municipal level for years — the number of municipalities taxing inventory fell from 34 in 2013 to 7 in 2018. Verify the current position with the state revenue department and the specific county before you commit.

State-by-state inventory tax table

This table covers the states that fully tax business inventory, with assessment dates, return filing deadlines, and freeport exemption availability where verified from state revenue departments and authoritative sources. Local rates vary widely within each state.

State	Assessment Date	Return Filing Deadline	Freeport Exemption Available	Notes
Arkansas	January 1	May 31	No	Lien attaches first Monday in January per Ark. Code Ann. § 26-34-101. Local rates vary by county.
Kentucky	January 1	May 15	No	Personal property must be listed between January 1 and May 15 per KRS 132.220.
Louisiana	January 1	April 1	Yes, limited	Inventory assessed at 15% of fair market value (La. Const. art. VII, § 18(B)). Voters defeated Amendment 4 on May 16, 2026, which would have let parishes reduce or exempt business inventory tax; Act 357 of 2025 was effective only if that amendment was adopted. For C corporations, the inventory tax credit is no longer earned for ad valorem taxes paid on or after July 1, 2026 (RIB 26-011). La. Const. art. VII, § 21(D) exempts certain goods imported from outside the United States, goods held in specified facilities for export, and goods in storage in transit, subject to the conditions stated there; the import exemption does not apply to goods held by a retail merchant as stock-in-trade.
Maryland	January 1	April 15	No	Assessed and taxed locally. Rates set by county and municipality.
Mississippi	January 1	April 1	No	Inventory valued as of January 1 or as average of prior 12 months. Personal property rendition due by April 1. State has been phasing out related capital stock taxes.
Oklahoma	January 1	March 15	Not verified	Assessment date January 1. Filing deadline March 15. Freeport exemption existence not confirmed from Oklahoma Tax Commission.
Texas	January 1	April 15	Yes, county-optional	Freeport exemption for goods in Texas ≤175 days and forwarded out of state per Comptroller guidance. Up to $125,000 exemption per location per taxing unit per Tex. Tax Code § 11.145 (2026). Oil, gas, petroleum excluded from freeport. Application due annually Jan 1–Apr 30.
Virginia	January 1	May 1	Limited	Generally assessed as of January 1 per Va. Code § 58.1-3515; localities may use July 1 per § 58.1-3011. Inventory taxed as merchants' capital at local option. Returns due by May 1.
West Virginia	July 1	September 1	No	Assessed and taxed locally. Assessment date differs from most states.

Partial-tax states (not shown in detail above):

• Alaska: Taxes inventory locally in some boroughs. Assessment procedures vary by borough.
• Georgia: Exempt at state level, but localities may tax. Many Georgia counties offer freeport exemptions ranging from 20% to 100% of inventory value under O.C.G.A. 48-5-48.1 and 48-5-48.2 (Level 1) or 48-5-48.5 and 48-5-48.6 (Level 2) — adoption is local-option and requires voter approval. Application required.
• Massachusetts: Inventory held as stock in trade is exempt for business corporations per G.L. c. 59, § 5, cl. 16(2). Manufacturing corporations classified by DOR are exempt from local tax on all tangible personal property except poles, conduits, wires, pipes, and certain electric-generation machinery.
• Michigan: Exempts inventory from property tax except inventory under lease.
• Vermont: Only 7 municipalities taxed inventory as of 2018, down from 34 in 2013. Effectively phased out in most of the state.

This table reflects Tax Foundation and state revenue department data as of 2026. Assessment dates, exemptions, and rates change. Confirm your position with the county assessor and a qualified tax advisor before selecting a location.

The partial states are partial in different ways

"Partial" is doing a lot of work in that second list, and the mechanisms are not interchangeable:

• Georgia exempts inventory at state level, but localities may still tax it. Over sixty percent of Georgia counties and cities have adopted freeport exemptions, which can exempt 20%, 40%, 60%, 80%, or 100% of inventory value depending on what the local governing authority has adopted. Georgia offers two levels: Level 1 categories include: goods in process of manufacture and raw materials (no holding limit); Georgia-manufactured finished goods held by the original manufacturer up to 12 months from manufacture; finished goods stored on January 1 in a warehouse, dock or wharf and destined for shipment outside Georgia, up to 12 months from storage; fulfillment-center stock stored on January 1, up to 12 months. Level 2 covers inventory that does not qualify for Level 1. Applications must be filed with the county Board of Tax Assessors.
• Michigan exempts inventory from property tax except for inventory under lease — meaning if you lease inventory to another party, that leased inventory remains taxable.
• Louisiana taxes inventory locally at 15% of fair market value (La. Const. art. VII, § 18(B)). Voters defeated Amendment 4 on May 16, 2026, which would have allowed parishes to reduce or exempt business inventory from property tax; Act 357 of 2025, which provided for optional parish exemptions, was effective only if that amendment was adopted. For ad valorem taxes paid on or after July 1, 2026, C corporations and certain estates and trusts can no longer earn the state inventory tax credit (RIB 26-011); S corporations and entities taxed as partnerships can continue to earn it.
• Vermont has been phasing inventory taxation out at the municipal level. Only 7 municipalities taxed inventory as of 2018, down from 34 in 2013. For most of Vermont, inventory is no longer taxed.
• Alaska taxes inventory locally in some boroughs, with rates and rules varying by borough.

The lesson generalises: in this area the exemption machinery matters as much as whether a tax nominally exists.

Freeport exemptions

Several inventory-taxing states offer a freeport exemption, which removes from the tax base goods that are in the state only temporarily on their way somewhere else — typically finished goods held for shipment out of state within a defined window. This is the single most important mechanism for distribution operations, because a distribution centre is precisely the case freeport exemptions were designed for.

How freeport exemptions work by state

Texas offers a freeport exemption for goods acquired in or imported into Texas that are detained for 175 days or less and then forwarded to a location outside the state. The exemption covers goods held for assembling, storing, manufacturing, repair, maintenance, processing, or fabricating purposes. Oil, gas, and petroleum derivatives are explicitly excluded. The exemption is county-optional: taxing units may elect to tax freeport goods notwithstanding the exemption, so you must verify whether the specific county has adopted it. Applications must be filed annually between January 1 and April 30 (or by May 15 if extended by the chief appraiser).

Georgia freeport exemptions are adopted locally by county or municipal governing authorities with voter approval. Level 1 categories include: goods in process of manufacture and raw materials (no holding limit); Georgia-manufactured finished goods held by the original manufacturer up to 12 months from manufacture; finished goods stored on January 1 in a warehouse, dock or wharf and destined for shipment outside Georgia, up to 12 months from storage; fulfillment-center stock stored on January 1, up to 12 months. Level 2 covers inventory that does not qualify for Level 1. The percentage of exemption can be set at 20%, 40%, 60%, 80%, or 100% of inventory value. Applications must be filed with the Board of Tax Assessors within the same period that returns are due, with partial exemptions available for late applications up to June 1.

Oklahoma assessment date is January 1, with returns due March 15. The existence and mechanics of a freeport exemption could not be verified from Oklahoma Tax Commission sources.

Louisiana has limited freeport provisions for goods in transit. The May 2026 constitutional amendment that would have expanded parish-level exemptions was defeated.

What to verify before relying on a freeport exemption

If you are considering a state on the list above and your inventory turns and ships onward, find out:

1. Whether the state offers a freeport exemption at all.
2. Whether the specific county or municipality has adopted it — it is often local option, not statewide.
3. What percentage of value is exempted (Georgia allows partial exemptions; Texas and Oklahoma are typically all-or-nothing).
4. What the holding-period limit is (175 days in Texas, 12 months in Georgia for most categories).
5. What you must file, and by when, to claim it — freeport exemptions are not automatic and require annual applications.
6. Whether your goods qualify — distribution inventory moving out of state typically qualifies; inventory for in-state consumption does not.

An operation that qualifies for a generous freeport exemption in an inventory-tax state can end up better off than one in a state with no inventory tax but higher rent or wages. Do not eliminate states on the headline tax alone.

The foreign-trade zone route

There is a second exemption path worth knowing. Foreign goods and domestic goods held for export inside a foreign-trade zone are exempt from state and local inventory taxes.

For an importer holding significant stock in an inventory-tax state, this can be a substantial standalone reason to use a zone — separate from the duty deferral and re-export benefits that usually drive the decision. See Foreign-Trade Zones Explained for whether a zone makes sense for your profile.

Bonded warehouses, in contrast, do not provide inventory tax exemption. Goods in a customs bonded warehouse remain subject to state and local inventory taxes despite the duty deferral. If inventory tax is a meaningful cost for your operation and you are choosing between a bonded warehouse and an FTZ, this difference can tip the decision. See Foreign-Trade Zone vs. Bonded Warehouse: The Comparison for the full trade-off.

What to do with this

Do not pick a state on this factor alone. Inventory tax is one line in a total cost that includes rent, labour, freight, and other taxes. States without inventory taxes are not automatically cheaper. See The True Cost of US Warehouse Space for the full cost breakdown.

Do quantify it before you sign. The calculation is roughly: assessed value of your typical inventory × the local rate, adjusted for any exemption you qualify for. Use your peak inventory if the assessment date falls near your peak — which leads to the next point.

Find out the assessment date. Inventory taxes are typically assessed on stock held on a specific date. Where that date falls relative to your seasonal cycle can swing the bill dramatically. Businesses with pronounced seasonality sometimes find that a warehouse in a neighbouring jurisdiction, or a different assessment date, matters more than the rate itself.

Ask the county, not just the state. Rates and exemptions are local. Your broker should be able to put you in touch with the county assessor, and a direct conversation before signing is worth more than any national summary — including this one.
