Cost to Appeal Property Taxes on a Condo (2026)

Appealing property taxes on a condo costs $129 flat with TaxDrop's self-serve packet, or 1% of the assessment reduction you actually win with a full-service protest — never a cut of your tax savings, and never a fee if the appeal comes back with no change, in 2026. The number that catches people off guard isn't the fee itself: it's that New Jersey is the one state TaxDrop serves where filing costs anything upfront, $5 to $150, non-refundable, before your county board of taxation even hears the case.

TL;DR

• How much does it cost to appeal property taxes on a condo: $129 flat with TaxDrop One, or 1% of the assessment reduction with a full-service protest.
• Full-service condo protests only run in Texas' 17 covered counties — everywhere else, TaxDrop One's flat fee is the paid option.
• New Jersey charges $5 to $150 upfront to file, non-refundable, the only state on this list with any upfront cost.
• 30-60% of properties are over-assessed and only about 5% of owners ever appeal, according to aggregated public-records data.

Why this matters

Most condo owners never check whether their county got the valuation right. Only about 5% of owners appeal in any given year, even though 30-60% of properties carry an inflated assessment, based on aggregated public-records data.

A condo isn't valued like a detached house. Your county typically leans on comparable unit sales inside your own building or complex, pulled from public records, rather than a broader neighborhood comp set. That narrower pool of comps is exactly why it's worth checking your number instead of assuming the county got it right. TaxDrop runs that comparison for free before you spend a dollar on either option.

How much does it cost to appeal property taxes on a condo?

Two cost structures exist, and which one applies to your condo depends on where it sits.

Cost

• TaxDrop One (self-serve): $129 per property, per tax year
• Full-service protest: 1% of the assessment reduction won

Coverage

• TaxDrop One (self-serve): Texas, California, Georgia, Florida, New Jersey, Maryland
• Full-service protest: Texas only, 17 counties

Fee if the appeal doesn't reduce your assessment

• TaxDrop One (self-serve): None charged for the analysis itself; the $129 covers filing the packet
• Full-service protest: None

Best for

• TaxDrop One (self-serve): Condo owners comfortable reviewing their own comps
• Full-service protest: Texas condo owners in a covered county who want a licensed consultant handling it

The free instant analysis comes before either fee. It tells you in under two minutes whether your condo looks over-assessed, so you're not paying $129 or committing to a protest on a hunch.

TaxDrop One for condos: $129 per property, per tax year

The self-serve packet is a flat $129 per property, per tax year, regardless of state. It pulls comparable unit sales from public records inside your building or nearby comparable buildings, packages the evidence, and walks you through filing it with your assessor's office, appraisal district, or board of tax assessors, depending on where your condo sits.

Pros: predictable cost that doesn't scale with the size of your reduction, available across all six states TaxDrop serves, and the analysis showing whether you're over-assessed is free before you commit.

Cons: you're the one filing and, in states that hold a hearing, presenting the case — there's no licensed consultant arguing it on your behalf.

Verdict: Buy if you want a low, fixed cost and you're fine reviewing the comps yourself. Skip it if your condo is in one of Texas' 17 full-service counties and you'd rather hand the whole thing off.

Full-service condo protests: 1% of the reduction you win (Texas only)

Full-service is licensed-consultant-led and limited to 17 Texas counties. The fee is 1% of the assessment reduction the consultant actually wins — not 1% of your tax bill, and not a percentage of dollars saved. No reduction means no fee.

For a condo, that means the consultant pulls comparable unit sales, files the protest with your county's appraisal district (CAD), and represents you at the informal hearing if one happens. Texas's informal success rate runs 80-90%, based on aggregated data.

Pros: hands-off from filing to hearing, and the fee only exists if the assessment actually drops.

Cons: it doesn't exist outside those 17 Texas counties — a condo in Austin might qualify; a condo in Dallas or anywhere outside Texas won't.

Full-service only covers 17 Texas counties; everywhere else, the flat packet is the paid option.

Why condo appeal costs vary

Cost isn't one number nationally because the process, the office, and the deadline all shift by state.

• Which state your condo sits in. Texas calls it a protest, filed with the appraisal district (CAD). California, Georgia, Florida, New Jersey, and Maryland call it an appeal, filed with an assessor, board of tax assessors, property appraiser, or SDAT.
• Whether full-service is available. The 1% fee only exists in Texas' 17 full-service counties. Outside those counties, the $129 TaxDrop One packet is the only paid option.
• New Jersey's upfront filing fee. $5 to $150, non-refundable, paid before the county board of taxation hears the case — no other state on this list charges anything upfront.
• How your specific condo gets valued. Comparable unit sales inside your own building carry more weight than broader neighborhood comps, which narrows the evidence pool compared to a single-family appeal.
• Your filing deadline. Texas is May 15; Georgia gives roughly 45 days from your Annual Notice of Assessment; Florida gives roughly 25 days from your TRIM notice; New Jersey is April 1 except Burlington, Gloucester, and Monmouth counties, which file January 15; Maryland's window runs roughly 45 days and only applies to the one-third of the state reassessed that cycle.
• HOA-maintained common areas. Some counties fold shared amenities into a building's overall valuation, which can shift your unit's assessed value more than it would for a detached home.

Is it worth appealing property taxes on a condo?

The $129 self-serve fee is worth it for most condo owners: 30-60% of properties are over-assessed, and appeals that succeed typically cut the assessed value 10-15%, based on aggregated data across TaxDrop's states in 2026. The math only fails to work if your county's tax rate is negligible or your condo's comps already look accurate.

Do condos get over-assessed as often as houses?

30-60% of properties are over-assessed, condos included — that range comes from aggregated data across property types, not a condo-specific figure. Condo appeals lean on comparable unit sales inside your own building, pulled from public records, which is the same sales-based evidence standard used for single-family appeals.

How much can you save appealing a condo's property tax?

10-15% is the typical annual savings from a successful property tax appeal, condo or house, according to aggregated data across TaxDrop's states. There's no guaranteed dollar figure — your actual savings depend on your county's tax rate and how much the assessed value comes down.

Owners juggling a condo alongside rental units often run into the same evidence questions on a bigger scale; the guide on property tax appeals for condo and HOA property owners walks through HOA-specific documentation. Texas condo owners weighing the two cost structures can see full county-by-county numbers in the property tax appeal cost in Texas breakdown.

FAQ

How much does it cost to appeal property taxes on a condo?

It costs $129 flat with TaxDrop's self-serve packet, or 1% of the assessment reduction won with a full-service protest in 2026. The self-serve fee is the same regardless of state; full-service only applies in 17 Texas counties.

Is there a fee if my condo tax appeal doesn't win?

Full-service charges nothing unless the assessment actually drops — that's the 1% fee. TaxDrop One's $129 packet fee applies once you decide to file, but the initial analysis showing whether you're over-assessed is free.

What is the full-service fee based on?

The 1% fee is based on the assessment reduction won, not on the tax dollars saved and not on your original assessed value. No reduction means no fee.

Does full-service protest cover condos outside Texas?

No. Full-service is limited to 17 Texas counties. Condo owners in California, Georgia, Florida, New Jersey, and Maryland use the $129 TaxDrop One packet instead.

Are there upfront costs to appeal a condo's taxes in New Jersey?

Yes. New Jersey charges $5 to $150 upfront to file, non-refundable, before the county board of taxation hears the case. It's the only state on this list with any upfront filing cost.

How is a condo's assessed value determined for an appeal?

Counties typically pull comparable unit sales from inside your own building or a similar nearby building, using public records. That's a narrower comp pool than a single-family home appeal usually draws from.

When is the deadline to appeal condo property taxes?

It depends on the state: Texas is May 15, Georgia gives roughly 45 days from your notice, Florida gives roughly 25 days from your TRIM notice, and New Jersey is April 1 except in three counties that file January 15.

Can HOA fees affect my condo's property tax appeal?

HOA fees themselves don't factor into your assessed value, but common areas the HOA maintains sometimes do, depending on how your county values the building. Your appeal focuses on your individual unit's assessed value.

One last thing

The deadline is the part condo owners miss most, not the fee. A $129 packet or a 1% success fee is meaningless if the window already closed — New Jersey's is the sharpest example, with three counties filing in January while the rest of the state gets until April 1. Check your specific date before you decide which of the two cost structures fits your condo.
