Selling or buying real estate in Los Angeles means navigating at least three layers of transfer tax: a City of Los Angeles base tax, a County tax, and a State tax — and if your property is worth more than $5.3 million, a fourth layer called Measure ULA. This guide walks through every calculation step in plain English, with two worked examples at each stage.
Step 1 — Calculate Net Value and Gross Value
Before the calculator touches any tax rate, it needs two foundational numbers: the Net Value and the Gross Value. These are the foundation of everything else.
Net Value is the sale price minus any mortgage or lien the buyer is taking over. It can never go below zero. The City of Los Angeles base tax, plus the County and State taxes, are all calculated on Net Value — because you're only being taxed on the actual equity changing hands, not on debt someone else already owed.[2]
Net Value = Sale Price − Liens Assumed (Minimum of $0 — can never be negative)
Gross Value is the sale price plus any liens. This is the number used for Measure ULA (the mansion tax), because that tax was designed to capture the full transaction size regardless of financing.[2]
Gross Value = Sale Price + Liens Assumed
Example A — Standard home sale with a mortgage
Sale Price: $800,000 | Liens assumed by buyer: $200,000
Net Value = $800,000 − $200,000 = $600,000
Gross Value = $800,000 + $200,000 = $1,000,000
Example B — Commercial sale with large existing loan
Sale Price: $10,000,000 | Liens assumed: $3,000,000
Net Value = $10,000,000 − $3,000,000 = $7,000,000
Gross Value = $10,000,000 + $3,000,000 = $13,000,000
Step 2 — Check Buyer Type Exemptions
Who is buying the property matters enormously. The calculator checks the buyer type before computing any tax, because certain buyers wipe out some or all of the taxes entirely.
Government buyers (federal, state, or local agencies) are completely exempt from every tax — City base, Measure ULA, County, and State. The rationale is that governments don't generate the kind of economic activity that transfer taxes are designed to capture.[1]
Nonprofit buyers — specifically IRS-recognized 501(c)(3) organizations, Community Land Trusts (CLTs), and Limited-Equity Housing Cooperatives (LEHCs) — are exempt from the Measure ULA surtax only. They still pay the City base tax, County tax, and State tax. The City of Los Angeles carved this out to encourage affordable housing acquisitions.[1]
| Buyer Type | City Base Tax | Measure ULA | County Tax | State Tax |
|---|---|---|---|---|
| Individual / Business | Owed | Owed | Owed | Owed |
| 501(c)(3) Nonprofit | Owed | Exempt | Owed | Owed |
| Community Land Trust | Owed | Exempt | Owed | Owed |
| Federal / State / Local Government | Exempt | Exempt | Exempt | Exempt |
Example A — Individual buyer at $6 million
Buyer type: Individual. No exemptions apply. The calculator proceeds with all four tax calculations in full.
Result: All four taxes computed normally.
Example B — City of Los Angeles acquires a building
Buyer type: Local Government. Sale price: $12,000,000.
Result: All four taxes = $0. Government exemption applies across the board.
Step 3 — City of Los Angeles Base Tax
If the property is inside the City of Los Angeles (not just LA County — the City itself), the calculator charges the City's base transfer tax. This has been in place since 1966 under Los Angeles Municipal Code Article 1.9.[2]
The rate is $2.25 per every $500 of Net Value — which works out to 0.45%. The calculator always rounds the Net Value up to the nearest $500 before applying the rate. This rounding-up rule is what makes it slightly different from a simple percentage calculation. No tax is charged if the Net Value is under $100.
Tax Units = Net Value ÷ 500, rounded UP to next whole number City Base Tax = Tax Units × $2.25
Key rule: The City base tax applies only to properties inside the City of Los Angeles. Properties in other parts of LA County — like Burbank, Pasadena, or unincorporated areas — do not pay this tax.
Example A — $100,000 sale, no liens, in LA City
Net Value = $100,000
Tax Units = $100,000 ÷ $500 = 200 (exactly, no rounding needed)
City Base Tax = 200 × $2.25 = $450
City Base Tax = $450
Example B — $7,000,000 net value, in LA City
Net Value = $7,000,000
Tax Units = $7,000,000 ÷ $500 = 14,000
City Base Tax = 14,000 × $2.25 = $31,500
City Base Tax = $31,500
Step 4 — Measure ULA (The Mansion Tax)
Measure ULA — officially the Homelessness and Housing Solutions Tax — was approved by LA voters in November 2022 and took effect April 1, 2023.[1] It applies on top of the base tax and is the single largest potential expense in this calculator.
Unlike the base tax, Measure ULA is calculated on the Gross Value (sale price plus liens), not the Net Value. It also uses a simple percentage rather than the per-$500 unit method. As of July 1, 2025, the thresholds are inflation-adjusted:[1]
If Gross Value ≥ $10,600,000 → ULA Tax = Gross Value × 5.5% If Gross Value > $5,300,000 → ULA Tax = Gross Value × 4.0% If Gross Value ≤ $5,300,000 → ULA Tax = $0
Notice that the higher tier takes full precedence: if your Gross Value hits $10.6 million, you pay 5.5% on the entire amount, not just the portion above the threshold. These thresholds are adjusted annually using the Consumer Price Index.
Important: Divorce, gifts, and trusts do not exempt you from Measure ULA. The City of Los Angeles does not recognize those state-law exemptions for its own taxes. A divorce transfer on a $7 million property still triggers ULA.[2]
Example A — $6,000,000 sale with $1,000,000 lien (Tier 1)
Sale Price: $6,000,000 | Liens: $1,000,000
Gross Value = $6,000,000 + $1,000,000 = $7,000,000
$7,000,000 > $5,300,000 but < $10,600,000 → Tier 1 applies
ULA Tax = $7,000,000 × 4.0% = $280,000
Measure ULA Tax = $280,000
Example B — $13,000,000 gross value (Tier 2)
Gross Value = $13,000,000
$13,000,000 ≥ $10,600,000 → Tier 2 applies
ULA Tax = $13,000,000 × 5.5% = $715,000
Measure ULA Tax = $715,000
Step 5 — Los Angeles County Tax
The LA County Documentary Transfer Tax is imposed under California Revenue and Taxation Code §11911 on all real property transfers throughout LA County — including those inside the City of Los Angeles. It's collected by the County Recorder at the time of recording.[2]
The rate is $0.55 per $500 of Net Value, using the same rounding-up method as the City base tax. However, the County tax recognizes several transfer types as exempt — situations where no real economic transaction is occurring:
Exempt transfers include: divorce (R&T §11927), gifts (R&T §11930), inheritance (R&T §11930), trust transfers without change of ownership, foreclosures (R&T §11926), certain partnership transfers (R&T §11925), and bankruptcy court orders (R&T §11921).[3]
Tax Units = Net Value ÷ 500, rounded UP County Tax = Tax Units × $0.55 (= $0 if transfer type is exempt)
Example A — $7,000,000 standard sale
Net Value = $7,000,000 | Transfer type: Standard Sale
Tax Units = $7,000,000 ÷ $500 = 14,000
County Tax = 14,000 × $0.55 = $7,700
County Tax = $7,700
Example B — $7,000,000 divorce transfer
Net Value = $7,000,000 | Transfer type: Divorce (R&T §11927)
Divorce transfers are exempt from County tax.
County Tax = $0
Step 6 — California State Tax
California imposes its own Documentary Transfer Tax under Revenue and Taxation Code §11911 at the same rate as the County: $0.55 per $500 of Net Value.[3] In practice, the County Recorder collects both taxes together (half goes to the county, half to the state), but the calculator shows them as separate line items for clarity.
The State tax follows the same exemption rules as the County tax — the same transfer types (divorce, gift, trust, foreclosure, etc.) that are exempt from County tax are also exempt from the State portion. Government buyers are always exempt. Individual sales with no special transfer type pay in full.
Tax Units = Net Value ÷ 500, rounded UP State Tax = Tax Units × $0.55 (= $0 if transfer type is exempt or buyer is government)
Example A — $1,000,000 sale, no liens, standard sale
Net Value = $1,000,000
Tax Units = $1,000,000 ÷ $500 = 2,000
State Tax = 2,000 × $0.55 = $1,100
State Tax = $1,100
Example B — $5,000,000 gift transfer
Transfer type: Gift (R&T §11930 — no consideration exchanged)
Gift transfers are exempt from both County and State documentary tax.
State Tax = $0
Step 7 — Add It All Together
Once all four components are calculated, the total transfer tax is simply the sum. This is what you'd need to budget for — and what will be collected at the time the deed is recorded by the LA County Recorder.[2]
Total Tax = City Base Tax + Measure ULA + County Tax + State Tax

Inputs: Sale Price $10,000,000 | Liens $3,000,000 | LA City: Yes | Buyer: Individual | Transfer: Standard Sale
Net Value = $7,000,000 | Gross Value = $13,000,000
City Base Tax = 14,000 × $2.25 = $31,500
Measure ULA = $13,000,000 × 5.5% = $715,000 (Gross ≥ $10.6M → Tier 2)
County Tax = 14,000 × $0.55 = $7,700
State Tax = 14,000 × $0.55 = $7,700
Total Transfer Tax = $31,500 + $715,000 + $7,700 + $7,700 = $761,900
Full Example 2 — Nonprofit acquiring affordable housing
Complete walkthrough
Inputs: Sale Price $6,000,000 | Liens $0 | LA City: Yes | Buyer: 501(c)(3) Nonprofit | Transfer: Standard Sale
Net Value = $6,000,000 | Gross Value = $6,000,000
City Base Tax = 12,000 × $2.25 = $27,000
Measure ULA = $0 (Nonprofit buyer — ULA exempt)
County Tax = 12,000 × $0.55 = $6,600
State Tax = 12,000 × $0.55 = $6,600
Total Transfer Tax = $27,000 + $0 + $6,600 + $6,600 = $40,200
