Indiana Form 103 Business Personal Property Return: Pools, Exemption, and Filing

Indiana Form 103 is the business tangible personal property return you file each year with your county assessor to report equipment, furniture, tools, and other movable business assets for local property tax. It’s due May 15, covers what you owned on January 1, and must be submitted with Form 104. Starting with the January 1, 2026 assessment date, the acquisition-cost exemption threshold jumps from $80,000 to $2 million, so most small and mid-sized Indiana businesses will only need to file a one-time exemption declaration instead of a full valuation return.¹

Who Has to File

Any person or entity that owns, holds, possesses, or controls business personal property in Indiana on the assessment date must file a personal property return under Indiana Code § 6-1.1-3-7. The assessment date is January 1. Whatever taxable property you have on hand that day is what you report on the return due May 15 of the same year.²

The obligation reaches beyond for-profit companies. Churches, nonprofits, and other tax-exempt organizations also file, even when they owe nothing.

Check the $2 Million Exemption First

Before you fill out a full Form 103, add up the original acquisition cost of every piece of business personal property you have in the county. Acquisition cost means the original purchase price of each asset, not its current depreciated value. If the total is below the statutory threshold, the property is exempt from taxation. For assessment dates before 2026, the threshold is $80,000. For January 1, 2026 and every year after, it rises to $2 million.¹

Being exempt does not mean skipping the filing. You still submit a personal property return containing a declaration that claims the exemption, states whether your property sits at one or multiple locations in the county, and gives the address of the location with the highest total acquisition cost. Once that declaration is on file, you don’t file again in future years unless your total acquisition cost crosses the threshold. Failing to file the declaration at all triggers a $25 penalty.³

Short Form or Long Form

Indiana offers two versions. Most businesses use Form 103-Short. You must use Form 103-Long if any of these apply:

You are a manufacturer or processor.
The total assessed value of your business personal property in the taxing district is $150,000 or more.
You are claiming deductions other than the enterprise zone credit, or reporting equipment not yet placed in service, special tooling, permanently retired equipment, or abnormal obsolescence.

If none of those apply, use the Short form.⁴ Businesses with multiple locations in the same taxing district file a single consolidated return covering all property in that district.

What to Have Ready Before You Start

Pull together your federal employer identification number (FEIN), the Department of Local Government Finance taxing district code for your business location, and a complete inventory of every tangible asset you own or control at that location. For each asset you need two data points: the year you acquired it and its original cost.

Sorting Assets Into the Four Pools

Indiana groups depreciable personal property into four pools based on each asset’s federal income tax recovery life. The pool determines how quickly the asset depreciates for Indiana property tax purposes.⁵

Pool 1: federal tax life of 1–4 years (computers, small tools, some software).
Pool 2: federal tax life of 5–8 years (office furniture, most machinery, vehicles).
Pool 3: federal tax life of 9–12 years (certain manufacturing equipment, land improvements).
Pool 4: federal tax life of 13 years or longer (some specialized industrial equipment, utility property).

If you’re unsure which recovery life applies to a particular asset, check the class life tables in IRS Publication 946 or your federal depreciation schedule. Getting the pool wrong can shift your assessed value enough to trigger an undervaluation penalty, so this step deserves care.

Calculating True Tax Value

Once each year’s acquisitions are sorted into the correct pool, multiply the adjusted cost of each group by the percentage factor from the state’s depreciation table. Indiana administrative rule 50 IAC 4.2-4-7 provides the factors. Reference points from the table:

Pool 1: Year 1 — 65%, Year 2 — 50%, Year 3 — 35%, Year 4 — 20% (fully depreciated after four years).
Pool 2: Year 1 — 40%, peaks at 56% in Year 2, then falls to a floor of 15% in Year 7.
Pool 3: Year 1 — 40%, peaks at 60% in Year 2, falls to a floor of 10% in Year 11.
Pool 4: Year 1 — 40%, peaks at 63% in Year 3, falls to a floor of 5% in Year 13.

Add the true tax value from all four pools. The total is the assessed value you report on Form 103.⁶ You must use these state-mandated percentages. The form does not accept values based on your own depreciation schedule or an independent appraisal. Abnormal obsolescence adjustments are available on the Long form for assets that have lost value beyond normal wear and tear.

Leased or Non-Owned Property

If you hold, possess, or control personal property you don’t own (leased equipment, property on consignment, borrowed tools), you are liable for the taxes on that property unless you can show the owner is already being assessed for it or a contract makes the owner responsible. Even when the owner pays the tax, you file Form 103-N listing all non-owned property at your location, including the owner’s name and address, a description of the property, and its value.⁷ Skip Form 103-N and the property can be assessed to you by default, since the assessor needs the information to route the tax correctly.

File Form 104 With Your Return

Every business filing Form 103 (Short or Long) must also complete Form 104, the Business Tangible Personal Property Return summary. Form 104 pulls together your taxpayer information, the assessed values from Form 103, and a handful of additional questions such as whether you made improvements to real estate you own or occupy in the taxing district. The assessor uses it for data entry and as the cover sheet for your filing.⁴ Submit both together. One without the other is incomplete.

Where and How to Submit

File your completed Form 103 and Form 104 with the county assessor in the county where your property is located. The deadline is May 15. You can request an extension from the county or township assessor, but the extension has to be granted before the deadline passes. Filing late and hoping for leniency doesn’t work.

Indiana developed the Personal Property Online Portal (PPOP-IN) at ppopin.in.gov as an electronic filing option.⁸ The authorizing statute, Indiana Code § 6-1.1-3-7(a)(3), originally covered assessment dates through 2025. If you’re filing for the 2026 assessment year, check the Department of Local Government Finance website or call your county assessor to confirm whether the portal remains available. Paper filing through the county assessor’s office is always accepted. You can download blank forms from the DLGF’s personal property forms page or pick them up at the assessor’s office.⁴

Late Filing and Undervaluation Penalties

Indiana Code § 6-1.1-37-7 stacks several penalties:

Initial late filing: $25, added to your next property tax installment the moment you miss May 15.
Still unfiled after 30 days but filed by November 15: an added 10% of the taxes due on the unreported property, capped at $10,000.
Filed after November 15: the added penalty rises to 20% of the taxes due, capped at $50,000.
Undervaluation: if the assessed value you report is more than 5% below what it should be, the county auditor adds a 20% penalty on the extra taxes resulting from the undervaluation.

These stack. A business that ignores the filing entirely and lets the assessor estimate the value can owe the $25 flat penalty, the 20% late-filing penalty, and a 20% undervaluation penalty on top of the taxes.

What Happens After You File

The county assessor reviews your calculations and pool assignments. If the assessor finds an error or disagrees with your reported value, they issue Form 113/PP, a Notice of Assessment/Change, showing the new assessed value they’ve assigned.⁹ From the date on that notice, you have 30 days to file a corrected return with the assessor or 45 days to file a formal appeal with the county’s Property Tax Assessment Board of Appeals.¹⁰ Do nothing within those windows and the Form 113 assessment stands. The appeal clock starts when the Form 113 is issued, not when your tax bill arrives the following calendar year, so waiting for the bill is too late.
