Making property taxes understandable.

Our mission.

Property taxes are the largest recurring expense for most homeowners, yet the process of understanding how they are calculated remains confusing and opaque. Assessment notices arrive in the mail with updated values, but rarely explain what that change means for your monthly budget. Local tax authorities use different formulas, assessment ratios, mill rates, and exemption structures — all of which make it difficult for ordinary homeowners to estimate the real impact on their finances.

MyTaxHike was created to bridge that gap. Our mission is to make property tax information transparent, accessible, and understandable for everyone, regardless of where they live or how their local government calculates property taxes. We believe that every homeowner deserves to know, in clear and simple terms, how much more they will pay when their assessment changes.

What we do.

MyTaxHike is a free property tax increase calculator that covers 190+ countries and 500+ states, provinces, and regions worldwide. Enter your current and new assessed property values, select your location, and we calculate your estimated annual, monthly, and 5-year tax increase using locally accurate effective tax rates.

In addition to the calculator, we publish original educational content about property taxes — including guides on how to appeal an assessment, explanations of tax terminology like mill rates and effective rates, state-by-state comparisons, and actionable strategies for reducing your tax burden. All of our content is written by our research team and reviewed for accuracy.

Our methodology.

We compile effective property tax rates from official government sources, tax authorities, and reputable research organizations. For each jurisdiction, we use the rate methodology most appropriate to that country's tax system:

• Effective rate: Used for most jurisdictions. The effective tax rate represents the total annual property tax paid as a percentage of the property's market value, accounting for all local levies and assessment ratios. This is the most common methodology in our database.
• Mill rate: Used in parts of the United States and Canada. One mill equals $1 of tax per $1,000 of assessed property value. We convert mill rates to effective rates for consistent calculations.
• Band-based: Used in the United Kingdom and some other countries. Properties are grouped into value bands, and tax is charged at a fixed annual amount per band rather than a direct percentage of value.
• Area-based: Used in parts of Europe and Asia. Property tax is calculated based on the property's physical area (square meters or square feet) rather than its market value, with adjustments for location, zone, and property type.

We clearly note which methodology is used for each country and region in the calculator results, so you always understand how the estimate was derived. Where sub-national data is not available, we use national averages with appropriate disclaimers.

Data sources.

Our tax rate data is compiled from the following categories of sources:

• Official government publications: State and provincial revenue departments, local assessor offices, and national tax authorities.
• Research organizations: Tax policy think tanks, academic studies, and international taxation databases.
• Industry data: Real estate associations and mortgage industry analyses that publish state-level effective tax rate comparisons.

Each country and region entry in our database includes a methodology note that cites the general source category and approach used to derive the rate. We encourage users to report inaccuracies so we can maintain the highest possible data quality.

Data updates and currency rates.

Tax rates change regularly as governments adjust budgets and reassessment cycles complete. We update our tax rate database every 1–2 months to keep estimates as accurate as possible. When a jurisdiction undergoes a major tax reform or rate change, we prioritize updating that data as soon as reliable figures become available.

Our currency exchange rates are hardcoded snapshots rather than live feeds. This approach ensures consistent calculations regardless of daily currency fluctuations. The date of the most recent exchange rate snapshot is displayed in the calculator's currency conversion section so you always know when rates were last refreshed.

Editorial standards.

All content published on MyTaxHike — including blog articles, guides, and FAQ answers — adheres to the following editorial principles:

• Accuracy: We fact-check all claims against official sources and clearly distinguish between universal tax principles and jurisdiction-specific rules.
• Originality: All content is written by our research team. We do not scrape, copy, or republish content from other websites.
• Objectivity: We present information without political bias or advocacy. Our goal is to inform, not to influence opinions on tax policy.
• Transparency: We clearly label estimates as estimates, note data sources and methodologies, and provide disclaimers where appropriate.
• Accessibility: We write in plain language that is understandable to homeowners who may not have a financial or legal background.
