With respect to our services and how we may be able to continue to assist you during these challenging times, below is an update on changes at Siepert & Co., LLP that will affect the manner in which we provide our services to you:

  • As an essential service, we will continue to be in operation to service your needs during the regular business hours of Monday through Thursday from 8am until 5pm and Friday from 8am unitl 1pm. We will be closed on Saturdays and Sundays.
  • All three of our office locations have reopened to the general public and we kindly request you consider wearing a mask into the premises and practice social distancing for everyone’s safety.  In addition, we still recommend sending all correspondence electronically whenever possible.
    • We can establish a secure portal for you to directly upload your data onto our website 
    • You can e-mail the information to your accountant
    • You may mail the information to our offices
    • If you find the need to drop off at our offices, you may do so during normal business hours.
  • We will continue to be available to assist clients over the phone, via video chat or through e-mail communications on an on-going basis.  Face-to-face meetings will require touch free temperature checks and screenings regarding any potential Covid-19 symptoms and will be scheduled at the staff members discretion.
  • Any information that has been received or that will be received will continue to be analyzed and processed with the goal of completing it in a timely basis.
  • Once your completed processing is available, we will notify you.  You may choose to have the information delivered in the following manners:
    • We can upload it to a secure portal on our website for immediate viewing and availability.  For income tax returns, the signature pages can then be printed at your location and executed.  This will allow for transfer back of your signed paperwork and ultimately the filing of those income tax returns. 
    • We can e-mail the information with password-protection.  This is less secure than the portal technology we utilize, but can be available if needed.  Note, if you choose either of these first two methods, we can either retain the hard copies on our end until the stay at home order is lifted or we can mail them to you.
    • We can mail the completed processing for your review and approval.
    • Client pickup of income tax returns will only be available during normal business hours

For Audit Clients: Because your engagement will be affected by this new policy, we would like to provide you with options to get your engagement started.

  • We can send you a comprehensive list of schedules and documentation that you have provided us in the past. This would include schedules and documentation. You can than scan and upload this information via e-mail or web portal.  This information will not be all inclusive so you will need to remain available to obtain additional information as the engagement progresses.
  • In addition to schedules that you normally prepare, you can box up all your records for the engagement and we will pick up those items. This will include but is not limited to all bank statements and reconciliations, investment statements, deposit and disbursement documentation and other source material.  The items we pick up will be subject to the previously mentioned quarantine period prior to our team beginning their work.
  • We will postpone your engagement until a future period when it will be safer for our staffs to interact with each at your location. Due to the unknown nature of the current pandemic we cannot guarantee a future time period but will attempt to accommodate as best we can.
