Property tax appeal software that keeps every county filing deadline on the parcel it belongs to

A property tax appeal is a challenge to the assessed value a local assessor placed on a parcel, filed to a board of review or equalization inside a window each jurisdiction sets for itself. The dates do not agree. King County takes petitions until July 1 or within 60 calendar days of the value notice, the District of Columbia allows 45 days at the second level, and Ohio gives 30 days to appeal a board decision. Neurobird tracks every parcel, deadline and exhibit on one case.

What property tax consultants and appeal firms actually deal with

Every county writes its own deadline and the master list is a spreadsheet one person maintains.
Evidence for a hearing is assembled from email attachments the night before.
A client asks where their parcel stands and the answer takes an hour of digging.

Why it stays broken

An appeal practice is a deadline problem wearing a valuation costume. The valuation work is skilled and the filing work is clerical, but the filing work is what loses cases, because every jurisdiction writes its own calendar and its own evidence rule. No national system models that calendar, so firms rebuild it in a spreadsheet each year and hope the person maintaining it does not leave.

In King County a petition must be postmarked by July 1 of the assessment year or within 60 calendar days of the value notice, and evidence is due at least 21 business days before the hearing.

If you or the Assessor disagree with our decision, parties can file an appeal with the Washington State Board of Tax Appeals within 30 days of the mailing date of our decision.

Who is this for?

The same appeal, three different practices.

Solo consultant

You file a few hundred parcels a year

The calendar is the business. You need every deadline in one place and a reminder that fires before it, not after.

Commercial practice

You appeal income producing property

Income and expense exhibits are the case. You need them attached to the round they were filed in rather than to a folder on a drive.

Law firm tax group

You take appeals to the next level

A board decision starts a short clock. You need the escalation window tracked as its own deadline with its own owner.

The case board, as your practice would run it

Tick a step to close it and watch the parcel move through filing, evidence and hearing with the clock intact.

How does Neurobird Property Tax Appeal work?

  1. Load the parcel

    Parcel, jurisdiction, assessed value, owner and the deadline that applies are captured once, so nobody rebuilds the county calendar in a spreadsheet each spring.

  2. File and evidence

    The petition, the comparables and every exhibit stay attached to the round they were filed in, with the date evidence was due sitting next to the date it actually went.

  3. Decide and escalate

    The board decision closes the round and starts the clock on the next level, which in Ohio runs 30 days from the date the board of revision mailed it.

What the rules say about assessment appeals

Filing windows in four jurisdictions, the evidence clock before a hearing, and the federal limit behind a client interest in appealing at all.

Property tax appeal software questions, answered

Key terms

What is a property tax appeal?
It is a challenge to the assessed value an assessor placed on a parcel, filed to a board of review or equalization inside that jurisdiction window. The windows differ: King County allows 60 calendar days from the value notice or until July 1, while Ohio gives 30 days to appeal a board of revision decision.

Does this replace our valuation model?

No. Your comparables and your income model stay where they are. This holds the parcel, the deadline, the exhibits and the decision, which is the clerical half that actually loses appeals.

How does it handle many jurisdictions?

Each jurisdiction carries its own filing window and evidence rule, and parcels inherit it. A deadline becomes a date on a case rather than a row somebody has to remember to update.

Can clients see status without emailing us?

Yes. Each parcel has one status a client can read: which round it is in, what was filed, when the hearing is and what the board decided. You choose what is published and what stays internal.
