PTAX-203 Forms

The Lake County Clerk's Office is a participant in the Illinois Department of Revenue's MyDec program which allows for the FREE online preparation and submission of real estate property transfer tax declarations. The MyDec program also allows users to track the status of and make corrections to electronically prepared PTAX-203 forms throughout the entire recording process.


Please register to become a MyDec user at https://mytax.illinois.gov/MyDec so you can submit electronically prepared PTAX-203 forms to any Illinois county that participates in the MyDec program.


A detailed set of instructions for the MyDec program can be found at https://www2.illinois.gov/rev/localgovernments/property/Documents/IDOR-PT1 MyDec Preparer Access Procedures.pdf and the Illinois Department of Revenue has a toll-free hotline dedicated to supporting the MyDec program.
