Welcome to the Laskey Costello Onvio Client Portal

We are pleased to announce that Laskey Costello is now offering a private and secure client portal for you on our website.

Beginning with the 2020 filing season, all clients will receive a paper copy of their tax returns along with access to an electronic version via the portal. Once we complete your tax return, you will receive an email notifying you that documents have been uploaded to the portal. This email will also include instructions on how to setup your username and password to access your account.

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 2020!
