Key Takeaways:
A property tax appeal in Maryland costs $0 if you file the paperwork yourself with your county's Supervisor of Assessments, or $129 per property for a flat-fee guided packet through TaxDrop One in 2026. Maryland doesn't have a contingency-fee, full-service appeal option — that pricing model exists only for TaxDrop customers in Texas.
TL;DR
- A Maryland property tax appeal costs $0 to file yourself or $129 per property with TaxDrop One's flat-fee packet in 2026.
- TaxDrop's contingency-fee, full-service option runs in Texas only — Maryland is flat-fee self-serve.
- Maryland reassesses one third of the state every year, so not every owner has a live appeal window each season.
- The $129 fee covers one property for one tax year, not a percentage of any reduction.
- Maryland's appeal window is roughly 45 days from your reassessment notice, or January 1 for off-cycle filings.
Why this matters
Most homeowners assume an appeal works the same everywhere. It doesn't. Texas protests run through an appraisal district and can carry a percentage-of-savings fee, but Maryland works through the state's Supervisor of Assessments (SDAT), and TaxDrop only offers a flat-fee self-serve packet there — not the contingency-fee service available in Texas.
That gap matters because 30-60% of properties are over-assessed based on aggregated public records data, and only about 5% of owners ever appeal. If you're one of the majority carrying an inflated Maryland assessment, knowing the real cost of fixing it in 2026 is step one, and it's a smaller number than most owners expect.
How much does a property tax appeal cost in Maryland?
A Maryland property tax appeal costs one of two amounts in 2026: $0 if you handle the research and paperwork yourself, or $129 per property if you use TaxDrop One's flat-fee packet. There's no percentage-of-savings fee anywhere in the state — that pricing model is reserved for TaxDrop's full-service Texas protests, which don't operate in Maryland at all.
File yourself with your Supervisor of Assessments
- Cost: $0
- Best for: Owners who can pull comparable sales and don't mind the paperwork
TaxDrop One flat-fee packet
- Cost: $129 per property, per tax year
- Best for: Owners who want the evidence packet built for them
Maryland's appeal process runs on three possible levels: the county Supervisor of Assessments first, then the Property Tax Assessment Appeals Board if you're not satisfied, then the Maryland Tax Court beyond that. Most owners resolve their case at the first level, which is where a stronger evidence packet does the most work.

The choice comes down to trading your own research time for a fixed packet fee.
Filing yourself: $0
Maryland lets any owner file an appeal directly with their county's Supervisor of Assessments at no charge. You'll need to pull comparable sales from public records, complete the appeal form, and make your case in writing or at a hearing. Maryland only accepts sales-based evidence — comparable assessments don't count the way they do in Texas or Georgia — so your comps have to hold up on their own.
Pros: no cost, full control over your case. Cons: hours of research, and one shot to get the evidence right before your deadline passes. Verdict: worth it if you already have comparable sales pulled and a few hours to spend.
TaxDrop One flat-fee packet: $129 per property
TaxDrop One starts with a free instant analysis, then charges a flat $129 per property, per tax year, if you move forward with the appeal packet. That fee covers comparable sales research, an evidence summary, and the paperwork prepared for you to file with your Supervisor of Assessments — you still submit it and represent yourself, since Maryland isn't a full-service state for TaxDrop.
Pros: you skip the sales-comp research, and the fee is fixed no matter how large your assessment correction turns out to be. Cons: it's priced as a flat fee rather than a contingency fee, so the $129 applies to the packet itself, not to a guaranteed dollar outcome. Verdict: worth it if you'd rather pay once than spend a weekend pulling comps.
Why the Maryland appeal cost varies
The base numbers are fixed — $0 or $129 — but what you actually end up paying and how often depends on a handful of factors specific to how Maryland runs assessments.
- Number of properties. Each property needs its own $129 packet through TaxDrop One — a landlord with three rentals pays for three separate filings, one per tax year.
- DIY vs. guided. Filing directly with your Supervisor of Assessments is free but time-consuming; the $129 fee is essentially buying back the hours you'd spend pulling and formatting comparable sales.
- Reassessment cycle. Maryland reassesses one third of the state's properties each year on a rotating three-year cycle, so whether you have a scheduled appeal window in 2026 depends entirely on your county's group.
- Missing the window. Maryland's appeal deadline runs roughly 45 days from your reassessment notice, with a January 1 filing option for off-cycle appeals. Miss it and you wait for your next scheduled reassessment — no extra fee, just lost time.
- Extra evidence. Hiring an independent appraiser for supplemental support is a separate cost outside anything TaxDrop charges, and it's only worth it on higher-value properties.
Is there a cost to file an appeal directly with Maryland's Supervisor of Assessments?
No, filing directly with your county's Supervisor of Assessments costs $0 in 2026. The only real cost is your time gathering comparable sales, since Maryland's process leans entirely on sales evidence rather than comparable assessments, and a thin evidence file is the most common reason a Level 1 appeal doesn't move the number.
How does Maryland's flat-fee appeal cost compare to Texas?
Maryland's $129 flat-fee packet is a fixed cost regardless of outcome, while Texas protest costs can run on a percentage-of-savings basis through TaxDrop's full-service option. Maryland doesn't have that full-service tier at all — TaxDrop One is the only path available there, and it's priced the same way whether your assessment is $250,000 or $800,000.
How often can I appeal my Maryland property tax assessment?
Maryland reassesses one third of the state's properties each year on a rotating three-year cycle, so most owners get a scheduled appeal window roughly once every three years. Off-cycle appeals are possible with a January 1 filing, but they're the exception, not the standard path, and they typically apply when a property changes hands or undergoes new construction.

FAQ
How much does a property tax appeal cost in Maryland?
A Maryland property tax appeal costs $0 if you file it yourself with your Supervisor of Assessments, or $129 per property through TaxDrop One's flat-fee packet in 2026. There's no percentage-based fee anywhere in the state.
What's the deadline to appeal a Maryland property tax assessment?
Maryland's appeal deadline is roughly 45 days from your reassessment notice, with a January 1 filing window for off-cycle appeals. Missing it means waiting for your county's next scheduled reassessment.
Does TaxDrop offer full-service property tax appeals in Maryland?
No, TaxDrop's full-service, consultant-led option operates in Texas only. Maryland owners get TaxDrop One's flat-fee self-serve packet instead.
Is Maryland's appeal process the same as Texas's protest process?
No, Maryland appeals go through the state's Supervisor of Assessments and SDAT, not a county appraisal district like in Texas. Maryland also only accepts comparable sales as evidence, not comparable assessments.
How much of my property could be over-assessed in Maryland?
Nationally, 30-60% of properties are over-assessed based on aggregated public records data. Only about 5% of owners ever file an appeal to correct it.
Can I appeal my Maryland property taxes every year?
No, Maryland reassesses one third of the state each year on a three-year rotating cycle, so most owners get a scheduled appeal window roughly once every three years. Off-cycle filings exist but are the exception.
What happens if I miss Maryland's appeal deadline?
You wait until your next scheduled reassessment, which is typically about three years out under Maryland's rotating cycle. There's no way to reopen the same-year window after the roughly 45-day deadline passes.
Is the TaxDrop One fee a percentage of my savings?
No, TaxDrop One charges a flat $129 per property per tax year regardless of the outcome. That's different from TaxDrop's Texas full-service model, which charges 1% of the assessment reduction won.
One last thing
Maryland is the outlier among the states TaxDrop serves: it's the only one that's state-assessed with no county appraisal district, and the unequal-appraisal argument that works in Texas and Georgia doesn't exist there at all. If your evidence isn't comparable sales, Maryland's Supervisor of Assessments won't weigh it — that rule affects your odds more than which $0-or-$129 path you pick.
