FAQ

Good to know

  • How much do your services cost?

    We quote fixed fees before any work begins. Individual returns start at $450, business returns at $1,200, and monthly bookkeeping at $350. There are no hourly surprises.

  • Do I need to come into the office?

    No. Most clients work with us entirely through our secure portal, video calls and e-signature. You're always welcome to visit, and we're happy to meet in person for planning sessions.

  • When should I send you my tax documents?

    As soon as you have them — ideally by mid-February for individuals and by the end of February for businesses. We'll send a personalized organizer in January.

  • Can you help if I haven't filed for several years?

    Yes. We regularly bring clients current on unfiled returns, negotiate penalties and set up payment plans. The first step is a confidential conversation.

  • What accounting software do you support?

    QuickBooks Online and Xero primarily. We can also work with QuickBooks Desktop and migrate you from spreadsheets or other systems.

  • Should my business be an S-Corp?

    It depends on your profit level, state, payroll and long-term plans. We run the numbers in a short planning session and give you a clear recommendation.

  • Do you work with clients outside the area?

    Yes. Roughly a third of our clients are in other states. Multi-state returns are one of our specialties.

  • How quickly do you respond?

    Within one business day, year-round. During filing season we add extended hours and Saturday appointments.
