Calculate Mello-Roos Community Facilities District taxes. See your total property tax with and without Mello-Roos assessments.
Mello-Roos is a special tax levied on properties within a Community Facilities District (CFD) to fund infrastructure such as schools, roads, parks, and utilities. Common in California new-home developments, Mello-Roos can add $1,000–$10,000+ per year to your property tax bill for 20–40 years until the bond is repaid.
Unlike regular property taxes based on assessed value, Mello-Roos is a fixed or formula-based assessment tied to the original CFD bond. The annual tax is specified in the bond documents and may increase by a fixed percentage (typically 2%) each year. Since Mello-Roos is not based on assessed value, it cannot be reduced through a property tax appeal.
This calculator shows your total annual property tax burden with and without Mello-Roos, helping buyers compare true housing costs between CFD and non-CFD neighborhoods. For investors, Mello-Roos significantly impacts monthly cash flow and must be factored into rental property analysis.
Homebuyers, investors, and real-estate professionals all benefit from precise mello-roos (cfd) tax figures when evaluating properties, negotiating deals, or planning long-term investment strategies. Save this calculator and revisit it whenever market conditions or your financial situation changes.
Many homebuyers are surprised by Mello-Roos taxes that can add $200–$800+ per month to their housing costs. This calculator makes the true tax burden transparent so you can compare neighborhoods, budget accurately, and make informed purchase decisions. Instant recalculation lets you compare scenarios side by side, so every buying, selling, or investment decision is grounded in solid financial analysis.
Total Annual Tax = Base Property Tax + Mello-Roos + Other Assessments Effective Tax Rate = Total Annual Tax / Property Value × 100 Monthly Tax Impact = Mello-Roos / 12
Result: $10,800/year total — 1.80% effective rate
Base property tax at 1% of $600,000 = $6,000. Adding $4,200 in Mello-Roos and $600 in other assessments brings the total to $10,800/year or $900/month. The effective tax rate is 1.80% vs the 1.0% base rate—Mello-Roos alone adds $350/month.
Regular property tax is based on assessed value (1% base rate in California under Proposition 13) and can be appealed if you believe the assessment is too high. Mello-Roos is a separate, additional tax based on a fixed formula unrelated to assessed value and cannot be reduced through appeals.
Mello-Roos can add 0.3–1.5% to your effective property tax rate. On a $600,000 home, that's $1,800–$9,000 per year in additional taxes. Always ask about Mello-Roos early in the home search process and factor it into your monthly budget and debt-to-income calculations.
For rental property investors, Mello-Roos reduces net operating income and cash-on-cash return. A $4,000/year Mello-Roos on a property generating $2,000/month rent significantly impacts profitability. Always verify total tax burden before purchasing investment property in a CFD.
Mello-Roos is a special tax authorized by the Mello-Roos Community Facilities Act of 1982 in California. It allows local governments to create Community Facilities Districts (CFDs) that issue bonds to fund infrastructure for new developments. Property owners within the CFD pay an annual special tax to repay the bonds.
Mello-Roos taxes vary widely from $1,000 to $10,000+ per year depending on the CFD's bond size and the property's formula allocation. Typical amounts for single-family homes range from $2,000–$6,000 annually. The exact amount is specified in the CFD's Rate and Method of Apportionment.
Mello-Roos bonds typically mature in 20–40 years from issuance. Once all bonds are repaid, the special tax terminates. Some CFDs have shorter terms of 15–25 years. Check the CFD's bond maturity date to know when your Mello-Roos ends.
Mello-Roos taxes are deductible as property taxes on your federal income tax return, subject to the $10,000 SALT (state and local tax) deduction cap. If your total state, local, and property taxes exceed this cap, the deduction benefit is limited.
Yes. Properties in Mello-Roos districts often sell for less than comparable non-CFD properties because buyers factor in the additional tax burden. The discount roughly equals the present value of future Mello-Roos payments, though this varies by market and buyer awareness.
Mello-Roos is a California-specific mechanism, but other states have similar special tax districts (STDs, SIDs, BIDs) that fund infrastructure through assessments. The concept of bond-funded infrastructure taxes on new development exists nationwide under different names.
