If you hire employees, you must comply with payroll tax withholding requirements under 26 U.S.C. §§ 3101–3406. The Gramm-Leach-Bliley Act (15 U.S.C. § 6801) requires accounting firms handling client financial information to implement safeguards protecting personal financial data and maintain privacy policies.

Accounting firms that prepare tax returns must comply with IRS Circular 230 (31 C.F.R. Part 10), which governs practice before the IRS and requires representation authorization.

The Sarbanes-Oxley Act (15 U.S.C. § 7201) creates additional compliance obligations if your firm audits public companies.

Portland and Multnomah County require accounting firms to comply with local business licensing and zoning regulations. If you operate a physical office in Portland, you must obtain a Business Licence from the City of Portland Bureau of Revenue and Financial Services, which costs approximately $50-$300 depending on gross revenue. Check zoning compliance through the City of Portland Bureau of Development Services to ensure your office location is zoned for professional services (typically B-1 or B-2 zones in downtown Portland, or offices in commercial areas).

Multnomah County does not impose additional licensing on accounting firms beyond state requirements, but if you operate outside Portland city limits in unincorporated areas, you must contact the Multnomah County Planning Division regarding zoning compliance. Some Portland neighbourhoods require conditional use permits if operating in residential zones. If your firm exceeds certain gross revenue thresholds, Portland requires annual business tax compliance.

Accountability offices handling payroll processing or tax preparation for Portland-area businesses must comply with the Portland Fair Chance Ordinance (PMC Chapter 12C) if hiring employees. The City of Portland requires all businesses to maintain Affirmative Action/Equal Employment Opportunity compliance (Title VII of the Civil Rights Act).

Professional liability insurance requirements are not mandated locally but are effectively required by client contracts and industry standards.

Oregon CPA licences and Public Accounting Firm registrations renew annually by June 30. The renewal deadline is strictly enforced; late renewals incur penalties. The annual renewal fee for CPAs is $275, and the firm registration renewal fee is also $275 (total $550 for a single-CPA firm). Renewal is entirely online through the Oregon Secretary of State Accountancy Board portal.

Continuing Professional Education (CPE) is mandatory. Each CPA must complete 80 hours of CPE during the two-year renewal cycle (40 hours per year average), with a minimum of 4 hours in Oregon Professional Responsibility. At least 4 hours must be live or group instruction; the remaining hours may be self-study. CPE must come from accredited providers (NASBA-approved). Documentation of completed CPE must be submitted with your renewal application.

If you miss the June 30 deadline, your licence is suspended automatically. Operating with a suspended licence is a criminal violation. You can apply for reinstatement within two years by paying the renewal fee plus a $50 late fee and submitting proof of required CPE. If you allow your licence to lapse for more than two years, you must retake the CPA Exam and reapply for certification. Online renewal is available 24/7 through the Oregon Secretary of State website. The renewal period begins April 1 and closes June 30 annually.

Operating an accounting firm or representing yourself as a public accountant without an active CPA licence in Oregon is a violation of Oregon Revised Statutes § 673.605. This is a Class A Misdemeanor, carrying a maximum criminal penalty of up to one year in jail and a fine up to $6,250. Repeat violations within 10 years elevate to a Class C Felony.

The Oregon State Board of Accountancy actively investigates unlicensed public accounting through complaint reports and audit sweeps. Violations are discovered through client complaints, IRS coordination, competitor reports, and online presence monitoring (websites claiming CPA services without licensure). The Board issues Cease and Desist Orders requiring immediate cessation of public accounting services.

Civil penalties include disgorgement of fees charged for unlicensed services and mandatory restitution to affected clients. The Board can impose administrative fines up to $5,000 per violation. Professional liability insurance is void if you operate without a licence, leaving you personally liable for all client damages. Operating unlicensed also creates tax compliance issues—the IRS does not recognize unlicensed preparers for certain representations, potentially exposing clients to audit liability that flows back to you.

Licence disciplinary actions include suspension (6 months to 2 years) or permanent revocation for fraud, incompetence, or gross negligence. A revoked licence requires a 5-year waiting period before reapplication. Settlements with the Board result in public disciplinary records accessible through the Board's online Lookup database, damaging professional reputation. Violating Board cease-and-desist orders triggers escalated penalties and potential criminal prosecution (Oregon Revised Statutes § 673.999).
