# 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 Neurobird Property Tax Appeal does

- Hold each jurisdiction filing window against the parcels that sit inside it
- Keep comparable sales and exhibits attached to the appeal round they were filed for
- Track the hearing, the decision and the next level appeal window on the same case
- Give the client one status page per parcel instead of a status email

## How it works

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.

## Questions

### 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.
