If you are buying a newly built home in Charles County, Maryland, there is a tax that most buyers never hear about until the bill arrives in the mail. The Charles County school construction excise tax has been on the books since 2003, and it applies to every new residential home in the county for ten years after the property receives its Use and Occupancy permit. It is separate from your regular property tax, and it does not appear on most mortgage escrow estimates unless someone specifically asks about it.
This post explains exactly what the Charles County school construction excise tax is, how much it costs, how it gets billed, who pays it, and what questions you should ask before you close. If you are a 100% disabled veteran who assumed you were covered by Maryland’s property tax exemption, there is something specific here you need to know before closing.

What Is the Charles County School Construction Excise Tax?
The Charles County school construction excise tax is a local tax assessed on all new residential construction in the county. It was created in 2003 to fund school expansion projects as the county grew. From 2000 to 2025, Charles County’s population jumped more than 46 percent, from 120,546 to 176,593 people. More residents means more school-age children, and the tax was designed to make new-home buyers help pay for the classroom space that growth requires.
Projects funded by the Charles County school construction excise tax include the $133 million expansion of La Plata High School. The county conducts an annual rate study to determine whether the amount needs to be adjusted based on actual school construction costs.
Despite being in place for over 20 years, many buyers, title companies, and some real estate agents do not mention it during the purchase process. That creates a problem, because this tax shows up as a separate bill from the Charles County Treasurer’s office, sometimes months after closing.
How Much Is the Charles County School Construction Excise Tax?
The most recent officially published figures for the Charles County school construction excise tax come from the county’s FY2025 budget documents:
- Single-family detached home: approximately $21,351 total
- Townhouse or attached home: approximately $21,398 total
- Multi-family unit: approximately $18,868 total
These are the total amounts assessed against the property over ten years, not the annual payment. On a townhome, that works out to roughly $2,140 per year, or about $178 per month added to your housing cost. A 7News I-Team report published in September 2026 cited a Charles County townhome owner who received a bill from the Treasurer’s office for more than $2,500, consistent with this installment structure.
| Home Type | Total Tax (FY2025) | Annual Installment | Monthly Equivalent |
|---|---|---|---|
| Single-family detached | ~$21,351 | ~$2,135/yr | ~$178/mo |
| Townhome / attached | ~$21,398 | ~$2,140/yr | ~$178/mo |
| Multi-family unit | ~$18,868 | ~$1,887/yr | ~$157/mo |
The county adjusts the rate annually. The FY2026 figures may differ from the FY2025 amounts listed above. Always confirm the current Charles County school construction excise tax rate directly with the Charles County Treasurer’s office at 301-645-0685 before you close.
Who Has to Pay the Charles County School Construction Excise Tax?
The Charles County school construction excise tax applies to any new residential home in the county, with one exception. According to county tax information:
- All new single-family homes are subject to the tax
- All new townhomes and attached homes are subject to the tax
- All new multi-family units are subject to the tax
- Age-restricted communities are exempt
The Charles County school construction excise tax follows the property, not the original buyer. If you purchase a home that is three years into its ten-year window, you inherit the remaining seven years of tax obligations. Any buyer of a Charles County home built within the last ten years should ask specifically how many installments remain before making an offer.
How the Tax Gets Billed: The 10-Year Payment Structure
The Charles County school construction excise tax is assessed the July 1st following issuance of your Use and Occupancy permit. The total is divided into annual installments and appears as a separate line item on your property tax bill each year for ten years.
Two things trip buyers up here. First, if you close in the spring, your first school construction excise tax installment may not arrive until the following summer or fall. That gap can catch you off guard if you built your housing budget around the initial mortgage estimate only. Second, the tax appears under a label like “School Construction Excise Tax” or, in some older county documents, “impact fee.” It is not folded into your base property tax line.
Your mortgage servicer’s escrow account may or may not include this tax. Ask in writing before you close. Some buyers have found it was not included in their initial escrow analysis, which means the annual bill arrives directly to them rather than being paid through escrow.
Does a 100% Disabled Veteran Exemption Cover the Charles County School Construction Excise Tax?
This question brought the Charles County school construction excise tax into the news in September 2026, and the answer matters if you are a military veteran buying new construction in the county.
Maryland provides a property tax exemption for veterans rated 100% permanently and totally disabled, or found 100% permanently unemployable, under Tax-Property Article Section 7-208. This exemption covers real property taxes on the veteran’s principal residence. There is no income cap. It is one of the most valuable benefits for disabled veterans relocating to Southern Maryland or buying a home here.
Here is the problem: Charles County’s position is that this exemption applies to real property taxes but does not extend to the school construction excise tax. The county told 7News that the two assessments are legally separate, and the veteran exemption does not automatically transfer.
Retired Air Force Master Sgt. Jannine Pete, a 100% disabled veteran with more than 20 years of service including time on the Presidential support team for Air Force One, purchased a three-year-old townhome in Charles County in August 2025. In July 2026, she received a Charles County school construction excise tax bill for more than $2,500. Her title company, her real estate agent, and county representatives had all led her to believe her 100% disabled veteran status would protect her. The 7News I-Team report from September 28, 2026 documented her case and the county’s response.
As of October 2026, no exemption specific to the Charles County school construction excise tax for disabled veterans has been publicly established. If you are a 100% disabled veteran and you are buying new construction in Charles County, confirm directly with the Charles County Treasurer’s office in writing whether your exemption covers this specific tax. Do not rely on verbal assurances from a builder, title company, or agent. If you are also using a VA loan in Southern Maryland, add this question to your pre-closing checklist.
Age-Restricted Communities: The One Exemption That Exists
If you are buying in an age-restricted community in Charles County, the school construction excise tax does not apply. The county’s tax information confirms this exemption. The rationale is straightforward: age-restricted housing does not add school-age children to the county’s enrollment projections, so it does not contribute to the school construction demand the tax is meant to fund.
If you are considering a 55-plus community in Charles County, confirm the formal age restriction is recorded on the deed or plat before assuming you are exempt. Not all communities that market themselves as “active adult” carry a formal recorded restriction. The marketing language and the legal exemption are two different things.
What Buyers Are Often Told vs. What the Bill Says
One of the persistent problems with the Charles County school construction excise tax is that buyers close without ever hearing the phrase. Here is the pattern I see in the field:
What buyers are told at closing: Your total monthly cost is X. That includes principal, interest, property taxes, and insurance. Your property taxes in Charles County are estimated at Y per month.
What arrives in the mail: A bill from the Charles County Treasurer’s office for the annual school construction excise tax installment, roughly $2,000 to $2,500 per year, that was not in the original estimate.
On a tight budget, a $2,000 to $2,500 annual surprise is not a minor adjustment. It is $175 to $210 per month that was not in your original housing cost calculation. That is real money.
The three questions every new construction buyer in Charles County should ask before signing anything:
- Is this property subject to the Charles County school construction excise tax?
- How many annual installments remain?
- Will my escrow account include this tax, or will I receive a separate bill from the county?
Charles County Growth and Why New Construction Keeps Getting This Tax
Charles County is one of Maryland’s fastest-growing counties. The population grew 46 percent between 2000 and 2025. That kind of growth creates real strain on school capacity, and the county’s policy response has been to require new construction to help fund the expansion. The school construction excise tax funds projects like the $133 million La Plata High School expansion that accommodate the new residents moving in each year.
There is nothing wrong with that policy in principle. What is wrong is when buyers walk into closings without knowing this obligation exists. The money goes to real infrastructure serving real children. The problem is a transparency failure in how the tax gets communicated, not the existence of the tax itself.
What to Ask Your Builder and Title Company Before You Sign
If you are buying new construction in Charles County, or a home built within the last ten years, these questions are non-negotiable before closing:
- Is this property subject to the Charles County school construction excise tax? If your agent, builder, or title company is unsure, contact the Charles County Treasurer at 301-645-0685.
- When was the Use and Occupancy permit issued? This starts the ten-year clock. A home permitted in 2018 would still owe installments through approximately 2028.
- How many annual installments remain? Know exactly where you are in the ten-year window before you make an offer.
- Will your mortgage servicer escrow this tax? Ask for a written answer before closing. Do not assume.
- If you are a 100% disabled veteran: Contact the Charles County Treasurer in writing and ask whether your exemption covers the school construction excise tax specifically. Do not assume the regular property tax exemption carries over.
Your agent should be raising these questions proactively. If they are not, that is a gap in your representation.
How This Tax Affects Your Monthly Budget: A Real Example
Using FY2025 Charles County school construction excise tax rates, here is what this looks like in a real budget. Confirm current rates with the county before using these figures for your own closing calculations:
New townhome, total tax assessed at approximately $21,398:
- Annual installment: approximately $2,140
- Monthly equivalent: approximately $178
- Duration: 10 years from U&O permit date
New single-family home, total tax assessed at approximately $21,351:
- Annual installment: approximately $2,135
- Monthly equivalent: approximately $178
- Duration: 10 years from U&O permit date
Add that $178 per month to your real housing cost calculation before deciding how much home you can afford in Charles County. It is not optional, and it does not go away until the ten-year window closes.
James’s Take: What I Tell Every New Construction Buyer in Charles County
I have been working with buyers in Charles County since 2011. The school construction excise tax is not a secret. It is on the county’s website, in budget documents, and documented by the Treasurer’s office. But it gets missed in transactions all the time because no one in the deal makes it their job to raise it. That is a failure of representation, not a failure of the county.
My job is to make sure you go into closing knowing exactly what you will owe, every month, for every year you own the home. If you are looking at new construction in Waldorf, White Plains, La Plata, or anywhere else in Charles County, I will pull the U&O permit date, confirm the remaining installment count, and build that number into your actual monthly cost estimate before you make an offer. If that changes what you can qualify for or afford, I would rather you know that before you sign than after.

Does a 100% disabled veteran exemption cover the Charles County school construction excise tax?
Not under the county’s current position. Maryland’s 100% disabled veteran property tax exemption covers real property taxes on a principal residence. Charles County has stated publicly that this exemption does not extend to the school construction excise tax, which is a legally separate assessment. This was raised in a September 2026 WJLA I-Team report. Disabled veterans should confirm their specific situation with the Charles County Treasurer’s office in writing before closing.
Who is exempt from the Charles County school construction excise tax?
Age-restricted communities are exempt. All other new residential construction in Charles County is subject to the tax. If you are buying in a 55-plus community, verify the formal age restriction is recorded on the deed or county plat before assuming the exemption applies.
Does the school construction excise tax transfer when a home is sold?
Yes. The Charles County school construction excise tax follows the property, not the original buyer. If you buy a home that is three years into its ten-year window, you take on the remaining seven years of installment obligations. Always ask how many years remain on any Charles County home built within the last decade before making an offer.
Will my mortgage servicer pay the school construction excise tax through my escrow account?
Some servicers include it; others do not. This is not automatic. Ask your lender and title company in writing before closing whether the Charles County school construction excise tax will be escrowed or billed directly to you by the Treasurer’s office. Do not assume it is included just because your other property taxes are.
