Quantinuum CPA

Quantinuum CPA is an MBA-led boutique firm founded by Pierre Chayeb, CPA, MBA, that delivers advanced tax strategy, executive compliance, and fractional CFO guidance. They specialize in proactive tax planning, multi-year backfiled taxes, and complex IRS resolution for high-earning professionals and entrepreneurs. The firm operates out of Solon, Ohio, serving clients in Cleveland and nationwide.

The firm offers a partner-only model that guarantees direct senior-level access without junior staff handoffs, ensuring total privacy and strategic continuity. Clients can choose between ongoing monthly bookkeeping or a one-time cleanup to get accurate, organized books. They also provide custom quotes for tax and international compliance work.

Pierre Chayeb, the founder, has a decade of experience with world-class organizations including Ernst & Young (EY) and DocuSign. He brings that same level of technical precision and multi-state compliance expertise to private clients who demand total transparency. The firm moves beyond basic tax filing to provide forensic-level reconstruction and proactive 2026 planning.

The firm provides comprehensive advisory in Arabic, English, French, and Spanish for a diverse global clientele. They handle U.S. business and individual returns, state filings, foreign-owned entity compliance, and cross-border tax planning. This multilingual support caters to their diverse global clientele.

To get started, clients can book a free consultation call where they review their goals and tax situation. The firm prioritizes flat-rate projects or monthly plans for predictable budgeting with no hidden hours. They offer clear, upfront fees based on needs with a transparent quote before any work begins.

The firm serves Solon, Cleveland, and clients nationwide, with a specific focus on helping small- and mid-sized businesses. They support entrepreneurs and international clients who want accurate books and reliable U.S. compliance. Their perspective is shaped by experience with large organizations to bridge the gap between impersonal firms and standard preparers.

The firm helps clients navigate options for LLC versus S-Corp taxation based on profit levels and self-employment tax savings. They assist with the choice between filing a Schedule C for LLCs or setting up payroll for S-Corps. This guidance helps businesses decide which structure is best for their specific profit margins.

Clients need income records, expense receipts, payroll documents, prior year returns, and any 1099s or K-1s for tax preparation. A common mistake to avoid is mixing personal and business expenses, which can be corrected by establishing good bookkeeping practices early. Organized records make tax preparation far less stressful for business owners.

The firm offers a proprietary plan to minimize IRS liability and free up capital to scale business growth. They focus on mastering the nuances of tax law and complex codes to optimize tax burdens before tax season hits. This proactive approach helps businesses discover and implement growth-minded strategies tailored to their goals.

The firm handles unfiled returns, back taxes, and unexpected IRS letters that act like engine drag on a growing business. They step in to handle the IRS directly and resolve past liabilities so clients can regain control. This service is part of their tax problem resolution offering.

The firm operates on a Monday through Friday schedule from 9am to 5pm. They provide clear, upfront flat rates with no hourly billing to ensure transparency. Clients can call (440) 999-0555 or email [email protected] to connect with the team.

The firm was founded to bridge the gap between impersonal Big-4 accounting firms and standard high-street tax preparers. They provide high-earning professionals and business owners with sophisticated financial leadership usually reserved for enterprise-level organizations. This approach ensures total privacy and strategic continuity without jargon.

The firm offers a weekly 'Real World' Strategy notes email series that includes playbooks used by successful clients. These notes are designed to keep margins fat and tax bills lean without being dry tax memos. Clients are added to this series upon completing a consultation form.

The firm provides a refund tracker that covers every state except Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. To establish identity, many states will ask for the exact amount of the expected refund in whole dollars. Clients can reach out for a copy of their return if unsure.
