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.
Common misconception: 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:
One helpful change worth knowing: businesses with less than $20,000 in total personal property are no longer required to report the property detail — you simply answer the property questions on the Annual Report and skip the personal property schedules. Many small service businesses and home-based LLCs fall under this threshold. You still must file the Annual Report itself every year, and failure to file is treated seriously either way. 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.
Key deadline: April 15 each year. The Personal Property Tax Return and the SDAT Annual Report are typically filed together through Maryland Business Express. A free 60-day extension to June 15 is available — but only if requested through SDAT's online extension system on or before April 15, and no further extension is permitted beyond that.
Missing the deadline triggers SDAT's penalty structure. A late return receives an initial penalty of 1/10 of one percent of your county assessment — with graduated minimums starting at $30 and a statutory maximum of $500 — plus an additional 2% of that penalty amount for each 30 days (or part thereof) the return remains unfiled. For businesses with substantial equipment, the assessment-based penalty can climb well above the minimums, and the underlying tax plus interest still comes due.
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 — and after continued non-filing, SDAT can forfeit the entity entirely.
It compounds: 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 add up quickly. The good news: Maryland allows catch-up filings — up to ten years of overdue reports can now be filed online — 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 and answer the property questions accordingly. 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:
How we handle this for clients: we file both the SDAT Annual Report and Personal Property Tax Return for all of our business clients as part of our annual engagement.

Book a Free ConsultationYes, most likely. If your business is registered as an LLC or corporation in Maryland, you are required to file an Annual Report every year regardless of size or location, along with the $300 fee. The good news for small home-based businesses: if your total personal property is under $20,000, you're exempt from reporting the property detail — but the Annual Report itself is still mandatory.
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. The process typically begins with a request for revision to SDAT's Personal Property Division and can proceed to the Maryland Tax Court if unresolved — with strict deadlines from the date of your assessment notice. We assist clients with the appeal process when the assessment appears to be in error.
