About
Property tax = assessed value × millage rate. NY/NJ/IL/TX have highest. HI/AL/CO lowest. Texas has high tax but no state income tax. California's Prop 13 caps reassessments at 2%/year - older owners pay way less.

Frequently asked questions
How accurate is the Property Tax Calculator?
It applies the standard formula. Accuracy is limited only by your input precision. For decisions with material consequences (taxes, medical, legal, structural), use the result as a starting point and verify with a qualified professional in the relevant field.
Is the Property Tax Calculator free to use?
Yes. 100% free, no signup, no payment, no API key. The site is funded by display ads around the tool but not inside the calculation flow.
Are my inputs saved anywhere?
No. All inputs stay in your browser tab. Closing the tab discards them. The site uses Google Analytics for traffic measurement (anonymized) but the analytics never see what you type into the form.
Can I use the Property Tax Calculator on my phone?
Yes. The tool is responsive and tested on iOS Safari, Android Chrome, and major desktop browsers. Touch targets meet Apple's 44pt and Google's 48dp minimum.
Does the Property Tax Calculator work offline?
Yes. Once the page has loaded, it works without internet. The calculation runs in JavaScript on your device.
How do I report a bug or suggest improvement to the Property Tax Calculator?
Email hi@3tej.com with the URL of this page and a description of what you saw vs expected. We typically respond within 72 hours.
Can I share results from the Property Tax Calculator?
Take a screenshot or copy the output. The page doesn't generate shareable URLs for specific calculations - inputs stay in your browser only.
Why are the results different from another property tax tool?
Most likely: different formula assumptions, different default values, different rounding rules, or different applicable rates. Check the methodology if both tools document it. Both can be valid for different scenarios.
Will moving to a higher bracket cost me money?
Almost never. Only the income above the bracket boundary is taxed at the higher rate. Income below it stays at the lower rate. The exceptions are 'cliff' benefits - some welfare programs end at hard income thresholds rather than phase out smoothly.
Is it better to invest in retirement or pay down debt?
Compare expected after-tax investment return to interest rate on the debt. Tax-advantaged retirement with employer match almost always wins. High-interest credit-card debt (>15%) wins over almost any investment.
How accurate is this calculator for my situation?
It applies the official brackets, standard deduction, and FICA/NI/CPP/EI rates for the year you select. It does NOT model itemized deductions, dependents, education credits, or self-employment - which can shift your final liability ±5-15%. Use the result as a starting estimate.
What's the difference between tax credits and deductions?
Deductions reduce your taxable income before tax is calculated. Credits reduce your tax bill dollar-for-dollar. A $1,000 deduction at the 22% bracket saves $220 in tax. A $1,000 credit saves $1,000. Credits are more valuable per dollar.
When should I update my withholding?
After major life events: marriage, divorce, baby, new job, large bonus, home purchase. Otherwise once a year, after filing, to align with the previous year's actual liability. The IRS Tax Withholding Estimator and HMRC PAYE adjustments handle this.
How income tax brackets work
Almost every modern country uses a progressive tax system: you pay a low rate on the first slice of income, a higher rate on the next slice, and so on. Critically, moving into a higher bracket does NOT raise the tax on income below the bracket boundary - only the income above it.
Example with simplified brackets: 10% up to $10K, 20% from $10K to $50K, 30% above $50K. On $60K income:
- First $10K: $1,000 tax (10%)
- Next $40K: $8,000 tax (20%)
- Last $10K: $3,000 tax (30%)
- Total: $12,000 tax = 20% effective rate, not 30%.
Marginal vs effective rate
Two numbers you'll see on every tax calculator:
| Rate type | Definition | Use it for |
|---|---|---|
| Marginal | Rate on your NEXT dollar of income | Deciding whether to take overtime, a bonus, or a second job. Estimating value of a deduction. |
| Effective / Average | Total tax / total income | Comparing tax burden across countries or states. Budgeting. |
Effective rate is always lower than marginal rate (unless you're in the lowest bracket). The gap widens as income rises.

Most-missed tax-saving levers
- Retirement contributions - 401(k), RRSP, EPF, NPS, super all reduce taxable income today. Employer matching is typically a 50-100% instant return.
- Health spending - HSA (US), salary sacrifice (UK), group health (India 80D) - pre-tax medical spend.
- Home loan interest - deductible in US (with SALT cap), UK BTL, India 80EEA, Canada (rental only), Germany.
- Education - 529 (US), Junior ISA (UK), 80C (India), RESP (Canada).
- Charitable giving - 60% AGI cap (US), gift aid (UK), 80G (India), donation tax credit (Canada).
- Capital losses - offset capital gains in same year + carry forward.
- Tax-loss harvesting - realize paper losses to offset realized gains. Watch the wash-sale rule (30 days US, 30 days UK).
