Frequently Asked Questions

Can I sit down with you in person this year? +

Yes! The office operates on a walk-in basis during tax season for in-person consultations. This is the most efficient means of gathering information with all tax documents.

Can I make an appointment to meet with you? +

During the tax filing season we operate on a walk-in basis without appointments. In the off season we work remotely and meet clients by appointment only.

Do I have to come to the office in person to have my taxes prepared? +

No, we accept documents via dropbox on the front porch or by mail. However, remote returns will have a longer turnaround time.

Do you have any remote / digital options? +

Yes, all existing clients have an online portal set up via SmartVault. You can upload tax documents digitally, but must notify the office when done. Remote returns have longer turnaround times and may need an extension.

What are your office hours for the 2025 tax season? +

May 10, 2026 - Jan 4, 2027, open by appointment only.

What services do you offer besides tax preparation? +

We offer bookkeeping, payroll and payroll tax preparation, S-corporation services, partnership returns, fiduciary/trust returns, and tax consulting year-round.
