At Zastenchik & Co. CPAs, tax planning isn’t a seasonal task—it’s a year-round process. We design tailored tax strategies that reflect your current goals and your future plans. Whether you’re navigating a major investment, planning for retirement, or trying to reduce your quarterly burden, we’re here to help you stay in control of the numbers.

Serving Clients Coast-to-Coast

Sagacity Tax & Accounting’s expertise isn’t limited by geography. Wherever you are in the U.S., our virtual tax services bring a licensed CPA to your laptop, tablet, or phone. We currently serve clients in more than 25 states, helping individuals, families, and small businesses handle tax preparation, tax planning, bookkeeping, and IRS representation entirely online.



Instead of being limited to the nearest storefront preparer, you can work with a nationwide tax accountant who understands complex, real-world situations: multi-state returns, moves, remote work, rental properties, and growing service-based businesses. You get the same “small-firm relationship feel” Sagacity is known for in Minnesota—just delivered virtually.

How Our Virtual Service Works

Working with an online CPA USA doesn’t need to feel complicated. We’ve built a clear, secure process so your experience is straightforward from the first conversation to the final filed return.


Typical steps:


  1. Initial consultation via phone or Zoom to understand your situation, goals, and deadlines.
  2. We provide a custom document checklist so you know exactly what to upload.
  3. You securely upload documents through our encrypted online client portal (or mail/fax if you prefer, though we recommend the portal for sensitive data).
  4. Your CPA prepares draft returns or reports, then walks you through the results via phone or video.
  5. You sign electronically where allowed; we e-file your returns and provide copies and confirmations.
  6. We remain available for questions, future planning, and year-round support.

Throughout the process, you’ll communicate directly with a CPA—by email, phone, or video—not a rotating call-center team. Data security and personal attention are built into every step.

We Do More Than “Year-End Cleanups”

At Zastenchik & Co., we work with business owners who want more from their CPA. Our team provides timely, understandable reports, structured planning meetings, and responsive answers all year long—not just at tax time. With us, you’re not hiring a bookkeeper—you’re gaining a financial partner.

Saving You Money with Sagacious Strategies

Nationwide Tax Expertise

Because Sagacity is a licensed CPA firm, we can handle federal returns and any state return you need, coordinating filings across multiple jurisdictions.


Whether you:


  • Moved from one state to another mid-year,
  • Live in one state and work remotely for an employer in another,
  • Own rental property or a small business across state lines,

we manage the multi-state tax requirements for you and help avoid both overpaying and underpaying.



Whether you’re in a high-tax state, a state without income tax, or juggling a mix of both, our nationwide tax accountant capabilities ensure compliance with all applicable rules.

Benefits of a Virtual CPA


Choosing a virtual CPA means you’re no longer limited to whoever happens to be down the street. Key benefits of Sagacity’s virtual tax services include:


  • Access to specialized expertise anywhere in the U.S.—not just in your city.
  • Time savings: no office visits needed; everything is handled online or by phone.
  • Flexible meeting times that can accommodate different time zones and busy schedules.
  • The same individualized advice and “small-firm feel” as an in-person relationship—not a call-center experience.
  • Secure document exchange through an encrypted portal specifically designed for confidential tax and financial information.


Many clients tell us their virtual experience feels just as connected as meeting face to face—often more, because it’s easier to schedule quick check-ins when questions come up.

Frequently Asked Questions – Virtual Services


  • Can my CPA be in another state?

    Yes. It is legal to use an out-of-state CPA for federal tax preparation, and Sagacity prepares returns for clients in over 25 states. CPA licenses are state-specific, but tax preparation is federally authorized; we maintain required credentials (such as PTIN) and ensure compliance with the rules in every state we work in.

  • How do virtual accounting services work in practice?

    Everything happens through secure digital tools—an encrypted portal for documents, e-signatures where allowed, and meetings via phone or Zoom. We follow a clear workflow so you always know what we’re working on and what we need from you next. Most clients find this smoother than traditional office visits.

  • How do I send you my documents securely?

    We provide an encrypted online portal specifically for document upload and sharing. You can also mail or fax documents if necessary, but we recommend the portal for sensitive data like Social Security numbers and bank details.

  • Will communication be difficult if we never meet in person?

    Not at all. We schedule regular check-ins via video or phone and respond promptly to emails. Our clients across the country often say it feels like we’re just next door because of how accessible and responsive we are.

  • What about time zone differences?

    We already serve clients from East Coast to West Coast and are used to finding mutually workable meeting times. When needed, we can offer extended hours during busy seasons to accommodate different schedules and time zones.

  • Do virtual clients get the same services as local clients?

    Yes. Virtual clients have access to the full range of Sagacity services—tax preparation, tax planning, bookkeeping and accounting, and IRS representation. The only difference is how we meet and exchange information, not what we can do for you.
