Appeal your Colorado property taxes yourself.
A guided workbook for homeowners preparing their own appeal. Turn your notice, property records and supporting documents into an organized filing plan.
Have a notice or a property-record question? Start with a plan.
The $29 kit helps you check what needs investigating, organize the evidence you collect, and work through the filing steps. Use it if you want a structure for doing the preparation yourself.
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.
- State-specific process guidance with official-source links
- Evidence organizer and filing checklist
- Ready-to-edit appeal-letter template
No setup required to buy. Add optional details below for a personalized PDF, or complete the editable fields yourself after download. See a completed preparation example.
Turn your question into an organized preparation draft
Get a preparation plan, the Colorado process guide, three fillable worksheets and an editable letter. Optional setup below carries your question and document list into the paid PDF.
Personalize your included letter and evidence organizer
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.
County Assessor - protest / objection to real property valuation
Official local property assessment appeal form or written appeal
This is the Colorado 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.
Open official filing instructionsAdd evidence you have already found (optional)
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.
See setup and purchase options · $29Preview your setup before checkout. You gather and verify evidence, complete required local forms, and file yourself.
After purchase: your preparation plan, the complete state guide, three fillable worksheets, official-source links and editable appeal letter. The full evidence organizer and letter are not included in this excerpt. You gather evidence and file yourself.
Prepare your Colorado 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 Colorado appeal works
The short version, free. The paid kit adds the evidence workbook, filing controls, and editable letter.
- Start with the current assessment notice; it identifies the property, value, and usually the local appeal route.
- Confirm the controlling deadline and required filing instrument at the official source linked below.
- Build a concise evidence file around value, uniformity, condition, or record accuracy, limited to grounds allowed locally.
- File yourself and keep proof; AppealMyTax provides the workbook and templates but does not file or manage the appeal.
What to check on your assessment notice
- Notice date and appeal deadline.
- Parcel identifier, property characteristics, assessment, and any stated market value.
- The named appeal body, official form, filing method, fee, and signature requirements.
- Instructions for evidence exchange, conferences, or hearings.
