Louisiana doc fee cap: $436.00 and what it covers

• Louisiana caps the documentary fee at $436.00. A dealer cannot charge more than that, and a figure above it is a billing error rather than a negotiating position.
• The cap is inflation-indexed, so it moves on a schedule rather than staying fixed. The figure above is the one currently in force.
• The rule: La. R.S. 6:969.18(A)(2): capped at $436 for 2026 (CPI-U or 3%, whichever is less); LMVC bulletin B-2026-001..

• The doc fee is part of the taxable amount in Louisiana, so sales tax is calculated on it as well. A larger doc fee costs you more than the fee itself.
• Because the cap is a legal ceiling rather than a required charge, a dealer is free to charge less. It is a smaller lever than the vehicle price, but it is not fixed by law at the maximum.
• Taxed at Louisiana's 5% to 12%, a $436.00 doc fee really costs between $457.80 and $488.32.

• The doc fee is capped at $436 for 2026 (the base is $425; it adjusts every January for inflation, at most 3% a year). The dealer has to give you a written notice that it is not a mandatory state fee. Louisiana taxes charges a seller adds to make the sale even when they are billed separately, and no rule exempts the doc fee, so the calculator taxes it. The Department of Revenue has not ruled on the doc fee itself.
