Possible online services disruption due to Internet related outage

A worldwide technology outage is causing disruption to some State of Illinois online systems.  We are aware of this issue and are diligently working on restoration.

Property Transfer Tax Declarations and MyDec

Notice: The Illinois PTAX-203, Real Estate Transfer Declaration Fill-in Form program is available only for those Counties that are not currently utilizing the MyDec system.

MyDec at MyTax Illinois

The Illinois Department of Revenue (IDOR) updated our processing system and applications, effective September 7, 2021. This upgrade implemented enhancements and will improve the user experience on all applications, including MyDec.  All MyDec functionality will remain available, but the application has a new look and will redesign the entry of PTAX-203 information to present the entry screens in a user-friendly manner (ex. display fewer entry boxes on one screen and allow clean navigation backwards and forwards). For more information, see MyDec Helpful Resources under Resources below. 

MyDec at MyTax Illinois allows users to search for Illinois Real Estate Transfer Declarations (Forms PTAX-203, PTAX 203-A, PTAX 203-B), as well as Cook County and City of Chicago Real Estate Transfer Declarations, if applicable, without logging in to a MyDec account. Visit the MyDec at MyTax Illinois website to perform a search.
