What this means for a South Carolina lease
South Carolina’s Infrastructure and Economic Development Reform Act moved qualifying registered vehicles into the Infrastructure Maintenance Fee system. For a purchase or lease from a dealer, the fee is the lesser of 5% of gross proceeds or sales price and $500, collected in connection with first registration.
The cap is reached once the applicable value reaches $10,000. That means a $25,000 vehicle and a $55,000 vehicle can both show the same $500 state IMF. A worksheet applying 5% without the cap, or adding ordinary local sales tax to the same registered vehicle, deserves correction.
The fee is not a recurring percentage of the monthly lease payment. A lessor can capitalize the $500 and recover it through the payment, but the legal event remains the first South Carolina registration. Separate title, registration, property-tax, and dealer charges still need their own lines.
State-specific calculation
Worked example: South Carolina IMF cap
Assume the registered lease uses a $38,000 applicable dealer value. The example calculates the one-time state Infrastructure Maintenance Fee and a comparison equivalent over 36 months.
- Uncapped calculation
- $38,000 × 5%$1,900.00
- Statutory maximum
- Lesser of $1,900 or $500$500.00
- 36-month comparison equivalent
- $500 ÷ 36$13.89/mo
What the example proves: The official state fee in this illustration is $500, not $1,900 and not 5% of every payment. If the $500 is financed, the payment may increase by more than $13.89 because rent can apply to the capitalized amount.
What to check on the dealer worksheet
- IMF line: Look for Infrastructure Maintenance Fee or IMF rather than a generic monthly sales-tax percentage.
- Applicable vehicle value: Ask which gross-proceeds, sales-price, or fair-market-value figure was used before the cap.
- $500 cap: For values above $10,000, confirm the state IMF stops at $500.
- Registration timing: The fee is connected to first registration in South Carolina, even if the lessor later finances it.
- Other charges: Keep title, registration, county property tax, and dealer fees separate so none is mislabeled as additional IMF.
- Trade-in: Trade-in value is excluded from gross proceeds (S.C. Code § 12-36-90), but because of the $500 cap it changes the fee only when the value net of the trade-in is under $10,000.
If one of these figures is missing, ask for a revised itemized worksheet before discussing the monthly payment. Use the lease worksheet guide to locate cap cost, residual, rate, fees, and total drive-off.
Why older South Carolina lease guides can be misleading
Some older lease charts describe South Carolina as taxing monthly payments. The IMF system took effect July 1, 2017, and current SCDOR material ties the vehicle fee to registration with a 5% calculation capped at $500.
A lease of a vehicle registered or titled in South Carolina is exempt from state and local sales and use tax under S.C. Code § 12-36-2120(83), because the one-time IMF applies instead. County vehicle property tax is a different annual obligation and should not be confused with the one-time IMF.
South Carolina lease-tax questions
Why is South Carolina lease tax usually $500?
The state IMF is 5% of the applicable value but cannot exceed $500. Any vehicle value of $10,000 or more reaches that cap.
Does South Carolina charge IMF on every lease payment?
No. The IMF is a one-time fee tied to first registration. A lessor may finance it, which can make its cost appear inside the payment.
Is South Carolina county property tax the same as IMF?
No. The one-time state IMF and recurring county vehicle property tax are separate obligations and should appear as separate items or disclosures.
