Letter from our firm

Dear Clients,

We understand that everyone is concerned about the Coronavirus outbreak. And we are as well, which is why we are taking extra precautions to keep our clients and staff safe.

While the threat of Coronavirus exists, our firm is implementing the following safety guidelines:

Documents: Please refrain from dropping off your tax documents. Instead, please upload them to your secure web portal. Please refer to the below portal instructions. If you have any questions, please call Diane at (614) 854-9000 extension 207.

Alternatively, you can mail them to our office. Please note: If you choose to mail or drop off your tax documents, they will be quarantined for one week upon receipt.

Completed returns: When your return is complete, we will send you an email. If we do not have your email address, we will contact you by phone.

Return delivery: Returns will not be available for pick-up. Instead, your return will be available in your client portal. If you need help accessing your return, please let us know. Any mandatory city paper filings will be mailed to you via first-class postal service. In addition, any original tax documents we have will be mailed back to you in the same envelope. Please note: If you need us to assemble and mail your return to you, please send an email to

Extensions: If an extension is necessary, you will be notified.

Thank you for your cooperation during this time of uncertainty. Our main focus is the continued good health of everyone! We greatly appreciate your cooperation and business!
