Welcome to the Laskey Costello Onvio Client Portal

Once your portal username and password are established, you can log in to the client portal via our website and gain access to tax returns and other confidential  documents anytime in a completely secure and simple manner.

We are always looking for ways to deliver an improved tax filing experience, and we hope that having the convenience and safety of electronic account access will make archiving and retrieving your tax returns easier than ever.

Thank you for the opportunity to serve you in 2024!
