This is a one-year post-purchase ad valorem budgeting scenario, not an appraiser's assessment, Tax Collector bill, eligibility decision or escrow calculation. A transfer ordinarily leads to reassessment at the following January 1; confirm the applicable year and timing with the appraiser. Entered purchase price is only a possible proxy for just value. The modeled assessed base subtracts only an already approved portability amount; it does not continue the seller's assessment or project a multi-year Save Our Homes cap.

For declared qualifying homestead, the first exemption is up to $25,000 of modeled assessed value and reduces both ad valorem bases, including school taxes. The additional exemption applies dollar-for-dollar to assessed value above $50,000, up to the selected cap, and reduces only the non-school base. The 2026 cap is $26,411, fully reached at assessed value $76,411. It never reduces school taxable value or non-ad valorem assessments. The appraiser, not a primary-residence toggle, determines legal qualification.

Use the already approved transferable Save Our Homes amount, at most $500,000 and no more than entered just value. The model does not compute the transferable benefit from an old home, decide upsizing/downsizing or approve an application. The statutory timing is tied to January 1 of the old homestead's abandonment year, not a generic period after closing; verify forms, dates and approval with the appraiser. Do not subtract a benefit already reflected in the entered value. Without homestead, portability and the additional cap are inactive.

The 2026 additional non-school homestead cap of $26,411 is verified from the published DOR table, not extrapolated from an illustrative future-CPI example. For 2027, this model accepts assumed rates only and an explicit assumed cap of at least $26,411. Every 2027 result is a projection, not a published cap, adopted rate or official assessment. Independently confirm future official figures before relying on a real bill. This 2027 projection retains the current-law two-tier homestead formula. Amendment 3 (CS/HJR 1F) awaits the November 3, 2026 vote; it requires at least 60% approval and would take effect January 1, 2027 only if approved. The proposed $150,000 for 2027 and $250,000 for 2028 are total assessed-value exemptions for non-school taxes, not the additional-cap input. The amendment is not modeled here.

County selects official lookup references, not a universal millage. Enter the parcel's school and non-school rates for the selected year, with adopted/proposed/assumed status. School totals include applicable operating, voted and debt authorities. One mill is $1 per $1,000 of taxable value. The reviewed 2026 county publications were proposed; this does not prove that no authority has adopted a budget. Prior municipal/code rates and countywide defaults cannot certify a current parcel rate. This tool does not fetch or validate the parcel's rates.

Non-ad valorem assessments are included only through an explicit annual quote, including confirmed 0; without inclusion, combined annual/monthly totals are not modeled, not a whole bill with zero extra charges. The optional seller comparison uses pre-discount ad valorem only; missing is not zero and a negative difference is retained. Other exemptions, payment discounts, prorations, penalties, settlement charges and multi-year assessment changes are not modeled. Monthly amounts are budgeting averages, not actual escrow or collector installments.

Inputs retain cents; each school/non-school tax component rounds half-up to cents before the annual ad valorem sum. A quoted non-ad valorem amount is added once only when included. Monthly budgets round the respective annual amount divided by 12; they need not match an actual payment schedule. Effective rate is annual ad valorem divided by entered just value, not by assessed value and not a rate on the combined bill. It is displayed with at most four decimal percent places; that rounded display is not the exact underlying ratio. These are declared model conventions, not new statutory rounding rules. The $2 billion money and 100-mill rate bounds are computational, not legal limits.

What This Calculator Does

Build a one-year Florida property-tax budget after purchase, with separate taxable bases for school taxes and non-school taxes. Enter the parcel's rates and declared assumptions rather than using a countywide default. 2026 uses the verified additional homestead cap; 2027 is an assumed projection. This is not an appraiser's assessment, eligibility approval or complete collector bill.

Who Is This For

Florida buyers, owners and real-estate professionals comparing a proposed tax budget with parcel documents. Confirm just value, homestead, portability and applicable dates with the appraiser; confirm rates and billed assessments through the relevant official sources.

How It Works

Choose the county for lookup only, then enter estimated just value in USD and both parcel-applicable millages. Select the year and rate provenance; 2027 permits assumed rates only and requires an explicit assumed cap of at least $26,411 if homestead is active. Declare qualifying homestead and enter only already approved portability. Include non-ad valorem charges only with an annual quote, including confirmed 0; otherwise combined totals stay not modeled. Optionally enter comparable seller ad valorem before payment discount, not a full bill. Confirm scope and review separate bases, budgets and the signed comparison.

Frequently Asked Questions

Can I use the price or the seller's assessed value for my post-purchase estimate?

Purchase price may be a starting proxy for just value, but the appraiser can determine a different value. Do not substitute the seller's assessed or taxable value or a value already reduced by portability/exemptions. A transfer ordinarily brings reassessment at the following January 1; confirm which year applies. The model uses estimated just value less an already approved portability amount. It does not preserve the seller's assessment or compute a continuing owner's multi-year Save Our Homes cap.

Why must millage for school taxes and non-school taxes be separate?

For declared qualifying homestead, the first exemption is up to $25,000 and reduces both ad valorem bases. The additional exemption applies to assessed value above $50,000 for non-school taxes only, up to the cap: $26,411 for 2026, fully reached at assessed value $76,411. It cannot reduce school taxes or non-ad valorem assessments. With hypothetical rates of 6 mills for school taxes and 14 mills for non-school taxes, just value $500,000, homestead and no portability, the component-rounded annual ad valorem estimate is $9,130.25. Those are illustrative rates, not county quotes.

Does choosing a county supply an official tax rate?

No. County selection provides official lookup references only. Enter millages for school taxes and non-school taxes for the actual parcel, year and taxing authorities; one mill is $1 per $1,000 of taxable value. School-tax totals include applicable operating, voted and debt levies. For 2026, declare adopted/proposed/assumed provenance; the tool does not verify it. The reviewed 2026 county publications were proposed, not a verified adopted parcel table. That does not mean no authority has adopted a budget. TRIM is proposed, not the final bill; old municipal/code rates are not universal county rates.

Can the calculator determine my portable Save Our Homes benefit?

No. Enter only the already approved transferable amount, including explicit 0, up to $500,000 and no greater than entered just value. The old home's listed benefit is not automatically the amount you may transfer, especially when the new property's value differs. The tool does not calculate upsizing/downsizing, decide eligibility or approve filing. Verify application, approval and deadlines with the appraiser; timing is tied to January 1 of the old homestead's abandonment year, not a generic period after closing. Portability is inactive without homestead.

Is the 2027 cap or rate official in this model?

No. 2027 accepts explicitly assumed rates for school taxes and non-school taxes only. With homestead active, supply an assumed additional exemption cap for non-school taxes of at least $26,411; no blank or hidden future default is accepted. The actual 2026 published cap is not a certification of 2027. All 2027 results remain projections, not official assessments, adopted rates or a forecast of future CPI. Confirm future published figures separately. The $2 billion input and 100-mill rate bounds are computational, not legal tax limits.

Is the total a full bill, and can I compare it with the seller's bill?

Only if you include an explicit annual non-ad valorem quote does the model combine that amount with ad valorem; even then it remains a modeled budget, not a certified full bill. An included confirmed 0 is different from excluded or unknown charges, whose combined totals are not modeled. The seller comparison accepts pre-discount ad valorem only, not a bill with additional assessments; blank is not zero and the difference keeps its sign. Monthly amounts are annual/12 budgeting averages, not escrow or collector installments. Effective rate uses annual ad valorem/entered just value, displayed to at most four decimal percent places—not the exact ratio.
