Sales Tax Filing Support in Louisiana

Tracking your Louisiana taxable sales against $100,000 in sales, keeping the liability account reconciled to what was actually collected, applying local rates to the right jurisdiction, and preparing and filing the return on the cadence the Louisiana Department of Revenue assigns you.

Parishes administer their own sales tax collection. The Remote Sellers Commission provides a single filing point for qualifying remote sellers only.

Registration runs through the Louisiana Department of Revenue. Once registered, Louisiana assigns a filing frequency based on your liability — monthly or quarterly by liability. We work the monthly close backward from those due dates, so the liability account is reconciled to what you actually collected before anything is filed. When collected tax does not tie to the return, that gap is a real obligation, and it is far cheaper to find monthly than annually.

Registration for a Louisiana sales tax permit runs through the Louisiana Department of Revenue. You will need the entity details filed with the Louisiana Secretary of State, your federal EIN, the date you first had activity in the state, and an estimate of expected volume — that last one is what the state uses to assign your filing frequency.

Register before you start collecting, not after. Once you cross $100,000 in sales, any tax you charge Louisiana customers is already the state's money whether or not you hold a permit — so collecting without one is a worse position than registering slightly late and filing a first return.

Louisiana assigns frequency by liability — monthly or quarterly by liability — and reassigns it as you grow. The notice goes to whatever address or portal contact the Louisiana Department of Revenue has on record, which is how businesses become delinquent without doing anything wrong.

A zero return is still a return. Once registered in Louisiana you file on your assigned cadence even in a period with no sales, and skipping it produces a delinquency notice for a business that owes nothing. Because Louisiana has no annual bracket, that check comes round at least quarterly.

Sales tax is a trust tax: the 4.45% you add to a Louisiana invoice was never revenue, so the consequences of getting it wrong are stiffer than for an ordinary underpayment. Penalties and interest generally run from the original due date rather than from when the problem was found, which is why a small monthly gap becomes an expensive number by the time anyone reconciles it.

Responsible-person rules in many states can attach that liability to owners and officers personally, and it is not reliably discharged by dissolving the entity registered with the Louisiana Secretary of State. Whether Louisiana would apply them to your situation is a question for your CPA or a state tax professional — what we do is keep the collected-versus-remitted figure right every month, so the question stays hypothetical.
