Every Maryland business is required to file an annual Personal Property Tax Return by April 15 — but it's one of the most commonly missed filings we see from new clients. Here's what it is, who has to file, and what happens if you don't.
The Maryland Personal Property Tax Return — officially Form 1 — is an annual filing required by the State Department of Assessments and Taxation (SDAT). It is completely separate from your federal or state income tax return, and it has nothing to do with your income. Instead, it reports the value of tangible personal property your business owns or uses in Maryland.
Based on the values you report, your county assesses a local personal property tax — essentially a tax on your business assets. In Frederick County, the personal property tax rate is set annually by the county council. The tax applies to most businesses operating in Maryland, regardless of whether they are profitable.
Many business owners assume their CPA or tax software handles this automatically along with their income tax return. In most cases, it does not — especially if you use national software or an out-of-state preparer. The Personal Property Tax Return is a Maryland state filing that requires separate attention and a separate deadline. We file it for all of our business clients every year.
The short answer: almost every business entity in Maryland. Specifically, you are required to file if you are any of the following:
Even if your business has no taxable personal property — for example, a purely service-based business with minimal equipment — you may still be required to file a return indicating zero value. Failure to file is treated the same as failure to pay. For a full overview of all Maryland business filing requirements, see our Maryland Tax Guide.
Maryland personal property includes tangible, movable assets used in your business. Common examples include:
Real property — land and buildings — is assessed and taxed separately through a different SDAT process and is not reported on the Personal Property Tax Return. Vehicles that are separately titled and registered are also generally excluded, as they are subject to the Maryland vehicle excise tax.
The process works in two steps. First, you report the original cost and acquisition year of each category of personal property on Form 1. SDAT then applies a depreciation schedule to determine the assessed value of your property. Second, your county applies its local personal property tax rate to the assessed value to calculate the tax owed.
In Frederick County, the personal property tax rate has historically been in the range of $2.25 to $2.50 per $100 of assessed value, though rates change annually. A business with $100,000 in assessed personal property value would owe approximately $2,250 to $2,500 in Frederick County personal property tax.
April 15 each year. The Personal Property Tax Return and the SDAT Annual Report are typically filed together through Maryland Business Express. Extensions are not generally available for the Personal Property Tax Return — unlike income tax returns, there is no automatic extension option.
Missing the April 15 deadline triggers Maryland's penalty structure immediately. Penalties for late filing of the Personal Property Tax Return can reach up to 25% of the tax due, plus interest that accrues from the original due date. There is also a $30 minimum penalty per return.
Beyond the financial penalties, a business that fails to file its Personal Property Tax Return will also be out of compliance with its Annual Report obligation — since both are typically filed on the same form. This puts your business in "Not Good Standing" status with SDAT, which can affect your ability to obtain financing, renew licenses, and enter into contracts.
We regularly see new clients who have missed the Personal Property Tax Return for multiple years without realizing it. The penalties, interest, and back taxes can add up quickly. The good news: Maryland generally allows catch-up filings, and we handle this process for clients who are behind. The earlier you address it, the lower the total exposure.
The Personal Property Tax Return is filed through Maryland Business Express at businessexpress.maryland.gov. Most businesses file Form 1, which covers the Annual Report and Personal Property Return together. The filing requires:
If your business has no personal property to report, you still complete Form 1 but check the box indicating no assessable personal property. Some businesses — particularly those in manufacturing or certain exempt categories — may qualify for partial or full exemptions on certain property types.
No — and this trips up many business owners. The personal property tax depreciation schedule used by SDAT is completely separate from the depreciation you take on your federal or Maryland income tax return. Even if you fully expensed a piece of equipment under Section 179 or 100% bonus depreciation on your income tax return, that same equipment is still reportable on your Personal Property Tax Return at its original cost, subject to SDAT's own depreciation schedule.
This means businesses that have aggressively used bonus depreciation — especially following the One Big Beautiful Bill Act's permanent restoration of 100% bonus depreciation — still owe personal property tax on those assets in Maryland. The two systems are entirely independent. See our OBBBA guide for more on federal depreciation changes.
Frederick County's mix of contractors, farms, restaurants, medical practices, and small manufacturers means personal property tax is a real and recurring obligation for most local businesses. A few Frederick-specific points worth knowing:
We file both the SDAT Annual Report and Personal Property Tax Return for all of our business clients as part of our annual engagement. We maintain a property listing for each client, track acquisitions and disposals throughout the year, and ensure the return is filed accurately and on time every April. If you're a new client who has missed prior years, we handle the catch-up process too. Contact us to get started.
Possibly. If your business is registered as an LLC or corporation in Maryland, you are required to file an Annual Report and Personal Property Tax Return regardless of size or location. If you have no assessable personal property, you file a return indicating zero value — but you still must file and pay the $300 Annual Report fee.
Your first Annual Report and Personal Property Tax Return will be due April 15 of the year following your registration. For example, if you formed your LLC in October 2025, your first filing is due April 15, 2026. You will report any personal property acquired from the date of formation through December 31, 2025.
Yes — it is a state form filed online through Maryland Business Express. However, accurately categorizing and valuing business personal property, applying the correct SDAT depreciation schedules, and identifying any applicable exemptions requires some familiarity with Maryland's assessment rules. Many business owners choose to have their CPA handle it to ensure accuracy and avoid penalties.
You have the right to appeal SDAT's personal property assessment. The appeal process involves filing a written protest with the Maryland Tax Court within 30 days of receiving the assessment notice. We assist clients with the appeal process when the assessment appears to be in error.
