Prepare your Maryland property tax appeal

Have a current notice? Check its deadline and reviewing office, verify the property details, then organize evidence that supports the correction you are requesting. Confirm official forms and fees before filing.

Preparing for a future window? Use the worksheets to review property records, list errors to investigate and plan your evidence. Buying now does not reopen a closed deadline or guarantee lower taxes.

The kit organizes those steps into a reusable guide and worksheets. It does not find comparable properties for you, file an appeal or replace your local authority’s instructions.

How a Maryland appeal works

The short version, free. The paid kit adds the evidence workbook, filing controls, and editable letter.

  1. Maryland's state agency SDAT (not your county) values your home, reassessing one-third of the state each year and mailing a Notice of Assessment in late December.
  2. If you got a notice, you have 45 days from the date printed on it. You choose a written, phone, video, or in-person hearing with an assessor, and all of it is free.
  3. If you were NOT reassessed this year, you can still appeal: file a Petition for Review by the first business day after January 1. Nothing arrives in the mail to remind you, which is why almost nobody does it.
  4. If the assessor says no, you have 30 days to your county's PTAAB board, and 30 more to the Maryland Tax Court. All three levels are free, and a residential assessment cannot be increased mid-cycle because you appealed.

What to check on your assessment notice

  • The appeal deadline printed on page 1, plus the Notice Number and Control Number. You need both to file online.
  • The total new market value. Is that genuinely what your home would sell for as of January 1? That single number is the only thing an appeal can change.
  • The assessment phase-in box: three separate figures for three years. The largest one is not this year's number, and the taxable figure shown for July 1 is what actually drives your bill.
  • The Homestead Tax Credit status line. If it reads "No Application" you have never applied and you are unprotected against future increases. Fixing that is a separate action from your appeal, and often worth more.

What’s inside

✓A plain-English Maryland appeal walkthrough across all three free levels: Supervisor, PTAAB, and the Maryland Tax Court.
✓The Petition for Review route that two-thirds of Maryland homeowners are entitled to use every year, with the deadline and the form.
✓The 60-day new-owner appeal, which is the strongest fact pattern in the state if you bought between January 1 and June 30.
✓How to get SDAT's own property worksheet and area sales listing for free, before your hearing, and what to look for in them.
✓The date-of-finality rule that decides which comparable sales actually count.
✓How the three-year phase-in works, so you calculate your real savings rather than the headline number.
✓The Homestead Tax Credit trap: why it is not an appeal, and how to tell from your notice whether you have ever applied.
✓A ready-to-edit appeal letter citing the right Tax-Property Article sections.

How it works

  1. Buy the kit — the PDF lands in your inbox instantly.
  2. Work out which route you are on first: a Notice of Assessment dated late December means 45 days from the date printed on it; no notice this year means a Petition for Review by the first business day after January 1; and a purchase between January 1 and June 30 means 60 days from the transfer.
  3. Gather the evidence on the checklist and edit the appeal-letter template.
  4. File the current instrument required by your local SDAT Supervisor of Assessments office before your deadline.
Deadline: Which deadline applies depends on which of three situations you are in. If you received a Notice of Assessment (mailed in late December to the third of the state being reassessed), § 14-502 gives you 45 days from the date of that notice, and the exact date is printed on the notice. Read it there rather than counting yourself, because it is a postmark deadline. If you were NOT reassessed this year, § 14-503 lets you file a Petition for Review on or before the date of finality for the next taxable year; the date of finality is January 1, and because January 1 is a legal holiday § 1-303 carries the deadline to the first business day after it. This right exists in any year of the cycle and nothing is mailed to prompt it. If you bought the property between January 1 and June 30, § 14-502 gives you 60 days from the date of transfer, and you should attach a copy of the deed if it was recorded after June 30 or the appeal may be dismissed. Escalation runs on two separate hard clocks: 30 days from the supervisor's final notice to PTAAB (§ 14-509, waivable only for good cause shown from physical inability), then 30 days from the PTAAB order to the Maryland Tax Court (§ 14-512, timely if postmarked in the window).

What Maryland charges to file

These are your county or state’s fees, not ours. Listed so there are no surprises.

  • Maryland Tax Court: explicitly no fee. The court states that there is no fee for filing a petition.
  • Supervisor's Level (SDAT): SDAT publishes no filing fee, and the Property Owner's Bill of Rights guarantees the appeal, the explanatory brochure, and the area sales analysis at no charge.
  • PTAAB: publishes no filing fee.
  • Copies of OTHER properties' comparable worksheets cost $1.00 per comparable, by check or money order payable to the State Department of Assessments and Taxation, and require an active appeal. Your own worksheet and the area sales listing are free.
  • Above the Tax Court, an appeal to Circuit Court does carry filing fees set by the Maryland Rules, and the appealing party must order the transcript at their own expense. That is beyond the scope of a do-it-yourself appeal.

Questions

Why is this $29 and not $49?
The Property Assessment Audit provides the filing or valuation output supported by your property's available evidence. Check your address and preview the available evidence before buying. This $29 kit is the state process guide, filing materials, evidence checklist, and appeal-letter template; you gather the property evidence yourself.
When is the Maryland property tax appeal deadline?
Which deadline applies depends on which of three situations you are in. If you received a Notice of Assessment (mailed in late December to the third of the state being reassessed), § 14-502 gives you 45 days from the date of that notice, and the exact date is printed on the notice.

What form do I file to appeal my Maryland property assessment?
the Notice of Assessment appeal form (or form SDAT-RP-PetRevForm) (Appeal of Assessment / Petition for Review), filed with your local SDAT Supervisor of Assessments office. The kit explains the filing steps and includes a ready-to-edit appeal letter.
Do you file the appeal for me?
No — this is a do-it-yourself product. You file with your local SDAT Supervisor of Assessments office. The kit provides the preparation workflow, evidence organizer, filing checks, and ready-to-edit letter.
What if it doesn't help?
30-day money-back guarantee, no questions asked. If the kit isn't useful, reply to your delivery email and we'll refund you.
Is this legal or tax advice?
No. It's general information to help you file your own appeal. Always rely on the date and instructions printed on your own assessment notice and confirm current requirements with your county.
