🔴 2026 Protest Deadline: May 15, 2026 — or 30 days after your Notice of Appraised Value is mailed, whichever is later. Miss this date and you waive your right to protest.
Collin County has seen some of the most dramatic property value increases in the Dallas-Fort Worth metroplex. Cities like Plano, Frisco, McKinney, Allen, Prosper, and Celina have drawn corporate relocations, new development, and rapid population growth — and appraisal values have followed. That growth is real. But the appraisal district’s numbers don’t always reflect market corrections, and too many property owners simply pay what they’re billed without questioning it.
You have the right to protest. In 2023, more than 115,000 Collin County properties were protested — and owners who did protest saved an average of nearly $1,975 per account. The tools below are your starting point.

McKinney · Realtors
RES-Real Estate Services is at 1833-A West Hunt Street, Suite 102 in McKinney, and it is not a conventional residential shop. The firm specializes in commercial property, farm and ranch, investment opportunities and development land across North and Northeast Texas, serving McKinney, Melissa, Princeton, Van Alstyne, Anna and the surrounding area. Owner and broker Charles B. McKissick has been in business since 1980.The team's background is unusually agricultural for a county now dominated by subdivisions: one agent runs a Black Angus cattle operation and has closed more than $100 million in transactions, another grew up on a working farm, another is a former rancher and roper, and another specializes in farm, ranch and development property.That matters for property taxes in a specific way. Collin County land is under enormous development pressure, and land carrying an agricultural or timber valuation is taxed on its productive use rather than its market value — a very large difference on a tract in the path of growth. Change the use, sell to a developer, or simply stop qualifying, and the county can assess a rollback: additional taxes recapturing part of the benefit from prior years, plus interest. Owners weighing whether to sell, lease or keep grazing a tract are making a tax decision as much as a real estate one, and the rollback exposure is worth understanding before anything is signed.This directory lists local businesses that work with property owners.

McKinney · Realtors
Carey Cox Company is a commercial real estate firm at 321 North Central Expressway, Suite 370 in McKinney, and it has been working Collin County since 1977 — more than forty years in one market. The firm offers investment sales, tenant advisory, project leasing, investment advisory and property management. Principals include Bill Cox, named 2022 Realtor of the Year by the Collin County Association of Realtors, and David Cox.Commercial property is taxed on a different footing than a house, and that difference is where a firm like this becomes relevant to a tax question. A house is usually valued by comparing it to nearby sales. An income-producing building is commonly valued on what it earns — actual rents, vacancy, operating expenses, and the capitalization rate applied to net income. So a protest on commercial property is frequently an argument about the rent roll and the operating statement rather than about what the building down the street sold for.Property management sits directly on top of that data. Whoever collects the rents and pays the bills is holding the evidence an income-approach argument runs on, and a landlord protesting a value usually needs it organized before the appraisal review board hearing, not after.Texas also requires businesses to render business personal property — equipment, furniture, inventory and fixtures — a separate filing from the real property value that catches many first-time commercial owners off guard. It is due each spring and carries its own penalty for filing late, separately from anything happening with the building's appraised value.Listing here is not an endorsement of any firm or any outcome.

McKinney · CPAs & Tax Preparers
Murray, Mensch & Brooks P.C. is a CPA firm at 6928 Mediterranean Drive, Suite 100 in McKinney. It was founded in 1986 as Patrick L. Murray, P.C. by Pat Murray, a longtime McKinney resident, and has practiced in the county for more than thirty-five years. The firm points to clients who have used it for personal and business returns for twenty years or more.Services cover individual income tax returns, small business accounting, tax projections and strategic planning, trust and estate tax planning, fractional CFO work and financial statement compilations.Trust and estate planning is the piece with the clearest property-tax consequences in Texas. How a home is titled decides which exemptions follow it. A residence homestead exemption belongs to an individual occupying the property, and moving a house into certain entities can complicate or forfeit it; a qualifying trust generally can hold a homestead, but the details matter and are worth checking before the deed is signed rather than after the exemption disappears. The over-65 school-tax ceiling and its transfer to a surviving spouse aged 55 or older are likewise applications filed with the appraisal district, not automatic adjustments, and they are easy to miss in the months following a death. Owners who inherit a McKinney home mid-year often find the exemption question lands before the estate is settled.Small business accounting also touches the annual business personal property rendition Texas expects from businesses owning equipment or inventory.Nothing here is tax advice, and a listing is not an endorsement.

McKinney · CPAs & Tax Preparers
Harman CPAs & Associates is a locally owned accounting firm at 1402 South Custer Road, Suite 102 in McKinney, led by owner John Harman and operating for more than fifteen years. It works with business owners, physicians, real estate professionals and individuals who need specialized tax guidance.The practice covers tax preparation and planning, business formation, payroll, bookkeeping and strategic business planning, and extends into less common territory: expatriate taxation, cryptocurrency tax preparation and multi-state business filings. It also handles IRS representation covering back taxes, liens and other resolution work.The real estate professional client base is the relevant detail here. Investors and agents who own rental property in Collin County face a set of property-tax realities owner-occupants do not. A rent house gets no residence homestead exemption and no ten percent homestead cap on annual appraisal increases, so its taxable value can move with the market in a way an owner-occupied home cannot. Non-homestead property also loses a temporary shield when the twenty percent circuit-breaker cap on certain non-homestead property expires at the end of 2026 — which makes 2027 planning worth starting early for anyone holding rentals, land or a second property. Anyone holding more than one property should know which one carries the homestead exemption, because only one residence can.The firm advertises a Best Financial Advisor in McKinney recognition and a Texas Monthly Five Star Wealth Manager award. Those are marketing distinctions, not regulatory credentials.A listing here is not an endorsement, and nothing on this site is tax advice. More Less

McKinney · Title Companies
WG Title is a title and escrow company at 7701 Eldorado Parkway, Suite 200 in McKinney. It was founded in 2011, is attorney-founded and operated with founding attorney Taylor Willingham still involved, and reports more than 10,000 closings since opening.The core work is what any title company does: a careful title search, owner and lender title insurance built on what that search turns up, and escrow and closing — securing funds, preparing accurate documents, coordinating the signing. The firm handles residential closings, commercial and investor transactions, and probate or inherited property work, and it issues title commitments and coordinates payoffs.That probate and inherited-property line is the one Collin County owners should notice. When a home passes to heirs and the deed is never cleared, the appraisal district can end up with no clean record of who owns the property, and a homestead exemption the heir qualifies for may not follow until ownership is sorted out. That is title and legal work, not a protest, and it is the kind of problem that quietly costs someone an exemption for years.For a protest, the useful artifact is the closing file. A settlement statement showing what you actually paid, on a dated and recorded transaction, is the most direct evidence of market value in the year you bought, and appraisal districts find it harder to argue with than any automated estimate. Collin County owners who bought recently should keep that paperwork somewhere they can find it in the spring.Inclusion in this directory is not an endorsement and implies nothing about outcomes.

McKinney · Title Companies
Money Law & Title's McKinney office sits at 208 East Louisiana Street, just off the historic downtown square, and operates as both a title company and a law firm. The Collin County office serves buyers, lenders, real estate agents and builders, covering residential transactions, commercial agreements, builder and developer support, and lender services.The combination is the point. A conventional title company can close your purchase; it cannot fix the legal problem the title search turns up. When one firm does both, the gap between finding a defect and resolving it gets shorter. The legal side covers real estate law, business law, wills, estate planning and probate.Several Texas property-tax headaches are really legal problems in disguise. An estate that was never probated leaves ownership unclear on the appraisal roll. A property held in a trust or an LLC may need different paperwork to claim a residence homestead exemption than the owner expects. Land split between heirs can lose an agricultural valuation if the use or the ownership changes without anyone filing anything. None of those are fixed by protesting a value.The same firm keeps offices in Greenville, Sulphur Springs, Emory, Terrell, Mount Vernon and Cooper, which matters for owners whose property sits across a county line from where they live — a common situation on the Collin and Hunt county border. The county the property sits in decides which appraisal district values it and which protest deadline applies, regardless of where the owner receives mail.A listing here is not an endorsement, and nothing on this site is legal or tax advice.
