Frequently Asked Questions

What is Know Property Tax?
Know Property Tax is a free educational resource that explains property tax in plain English — your state and county rates, whether you are overpaying, how to appeal your assessment, and the exemptions you qualify for. We are an independent resource, not a government agency and not a tax-appeal service.
Is it free to use?
Yes — Know Property Tax is completely free. We never charge readers for access to any of our guides or tools. There is no signup, no email gate, and no required form to read anything.
Do you provide legal, tax, or financial advice?
No. Know Property Tax is an informational site, not a law firm, an accountant, a financial advisor, a government agency, or a tax-appeal service. We provide general, plain-English information, and any estimate is illustrative only. We recommend you confirm your rate, any exemption, and any deadline with your county assessor and a licensed professional before you act.
How do you make money?
Know Property Tax earns revenue through display advertising (Google AdSense) and property-tax-appeal-service advertising — on appeal-related pages, where such a service operates, we may earn a commission if you choose to use one through our links (at no extra cost to you, always disclosed). These links are advertising, not a referral or endorsement, and none of these relationships influence our editorial content.
How current are the figures?
Property tax rates, median bills, and exemption amounts reset every year, and relief laws change through the year. Every page displays a Verified badge showing when it was last reviewed. Always confirm the current figure and any deadline with your county assessor.
