Need property-specific evidence first? Check available records for your address free. The kit does not determine whether you are overassessed or supply comparable properties. You verify your local requirements and file yourself.

Text-based PDF, up to 8 MB / 10 pages. Your file stays in this browser. Only details you confirm are included in your order. Photos and scanned notices currently need manual entry.
Copy details from your assessment notice. We use these to prepare your letter draft, worksheets and evidence list. These are your entries, not a verified property analysis. You can also buy now and fill them in later.
Start by checking the property facts and valuation basis. Record a specific question before choosing supporting evidence. Preparation does not reopen an expired filing window.
Optional notes are included in your purchase record and PDF. Do not include sensitive documents, account credentials or other people’s personal information.

This is the Maryland statewide route. Your county may use its own office, deadline or fee, so confirm those against your assessment notice or the official directory before you file. The jurisdiction exceptions in this guide list the ones we hold.

We organize your entries in the paid PDF; we do not verify them or generate comparable sales in the $29 kit. For each record include the address, sale price or assessment, date, official source and why it is relevant. Use the correct valuation date and local evidence rules.

Fictional teaching example: a property record lists 2,400 square feet; the owner’s floor plan lists 2,000. This is a question to investigate, not proof of overassessment or a savings estimate.

1. Define the question. Compare the area definitions, dates and source documents before assuming either number is correct.
Notice worksheet: property-record errors to verify
“The two area figures differ. Check whether they measure the same space, and verify the current property record before requesting a correction.”
2. Make an evidence list. Use the filing tracker to separate documents you have from documents you still need.
Filing tracker: evidence index
“To collect and label: current property record, dated floor plan and any measurements needed to resolve the difference. Record each source, date and page number.”
Example preparation summary · fictional, not filed
Question: Do the two area figures use the same measurement definition?
Document index: A — current property record; B — dated floor plan. Add source dates and page numbers before relying on either.
Unresolved: measurement basis, current facts and the appropriate local correction or appeal route.
Next action: verify those points with the official local source before making a correction request.
The useful result: one defined issue and a document checklist. You still verify the facts and the correct local filing route. No correction or tax reduction has been established in this example.
These illustrative entries show how to use two fields in the paid worksheets. The paid PDF carries your optional question and document list into editable worksheets and adds a preparation plan for your selected starting point. It does not contain this fictional property or a verified case for your home.
Your starting details
The notice worksheet also helps you record:
- Property address and parcel identifier
- State, county, township and reviewing body
- Assessment year and valuation date
Make this preparation package your own
Add your name, property details and question before buying. Your entries become a personalized letter draft and preparation plan in the paid PDF. You can edit them later; no need to start with an empty letter.

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.
- 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.
- 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.
- 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.
- 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
How it works
- Buy the kit — the PDF lands in your inbox instantly.
- 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.
- Gather the evidence on the checklist and edit the appeal-letter template.
- File the current instrument required by your local SDAT Supervisor of Assessments office before your deadline.
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.
