Knollmiller & Arenofsky

Knollmiller & Arenofsky is a Mesa-based law firm with a broad practice that includes tax law, business law, and estate planning. They've built a 5-star reputation among clients who value having a single firm handle multiple legal needs. Their tax practice covers both income tax matters and property tax appeals, which is useful for business owners and investors who want both handled under one roof. The firm serves individual property owners as well as business clients, and the overlap between practice areas is often practical. A business owner dealing with a commercial property assessment may also need help with entity structure or succession planning. Having attorneys who handle all of those issues means advice that accounts for the full picture, not just one piece of it.

Knollmiller & Arenofsky's property tax practice is part of a wider tax law offering that includes income tax representation, IRS matters, and business tax planning. On the property tax side, they handle assessment appeals for residential and commercial properties in Maricopa County, including petition filing, administrative hearings, and escalation to the State Board of Equalization or Arizona Tax Court if needed. For commercial clients, the firm brings additional context from their business law practice. If you're acquiring a property and want to understand the tax implications, structuring a business that owns real estate, or planning a 1031 exchange alongside an assessment review, the attorneys can coordinate those issues rather than treating them as separate matters. Estate planning intersects with property tax in specific ways, particularly around seniors' exemptions, the senior valuation protection option, and transfers of property within a trust or estate. Knollmiller & Arenofsky can handle the property tax and estate planning pieces together, reducing the chance of something falling through the cracks. They also assist clients with back-tax matters, penalty abatement, and other tax disputes outside the property tax arena.

The process starts with an initial consultation where the attorneys review your Notice of Value and discuss your goals. They'll explain the Arizona appeal timeline, assess whether your property looks over-assessed based on available data, and give you a candid recommendation on whether to proceed. If you decide to appeal, the firm files the petition before the April 25 deadline and handles communication with the Maricopa County Assessor's office. For residential properties, most cases resolve at the informal hearing stage. Commercial cases often require more detailed documentation and may take longer to settle. If the informal process doesn't produce a satisfactory result, they'll escalate to the Board of Equalization or, if warranted, Arizona Tax Court. Because they're a full-service law firm, there's no handoff involved. The same attorneys who started the case can finish it. For clients with combined property tax and estate or business needs, they'll typically structure consultations to address everything together rather than scheduling separate appointments for each issue.

Knollmiller & Arenofsky is based in Mesa and primarily serves Maricopa County, including the East Valley communities of Gilbert, Chandler, Tempe, and Scottsdale. Their practice extends to other parts of Arizona when clients have existing relationships or when a property tax case is connected to broader legal work they're handling. Mesa's central East Valley location makes them a practical choice for clients across the eastern half of the Phoenix metro who want to combine multiple legal needs.
