Louisiana Payroll Tax Compliance: A Guide for New Employers

Hiring your first employee is one of the biggest steps a Louisiana business owner takes. It also triggers a set of payroll tax obligations that do not exist when you work alone. Federal income tax withholding, Social Security and Medicare taxes, federal unemployment tax, Louisiana state withholding, and Louisiana unemployment insurance all come into play — each with its own registration, filing, and payment requirements.

The businesses that get payroll right from the start avoid penalties, interest, and the kind of administrative mess that can take years to unwind. The businesses that get it wrong often find out the hard way — through a notice from the IRS or Louisiana Works.

This guide walks through what every new Louisiana employer needs to know before the first paycheck is issued.

Step 1: Determine whether you are a liable employer

Before you can register for payroll tax accounts, you need to know whether your business is subject to Louisiana unemployment insurance law. Not every business with a worker is automatically liable — but most are.

Under Louisiana law, you become a liable employer if any of the following apply:

• You pay wages of $1,500 or more during any calendar quarter
• You have at least one individual employed during some portion of a day during 20 or more separate calendar weeks in a calendar year
• You acquire all or part of a business that was already subject to the law
• You are an Indian tribe, state instrumentality, political subdivision, or certain nonprofit or educational organization
• You are subject to the Federal Unemployment Tax Act (FUTA) and have at least one employee in Louisiana
• You pay $1,000 or more in any calendar quarter for domestic services in a private home, local college club, or fraternity or sorority chapter
• You employ 10 or more individuals for 20 or more weeks in a calendar year, or pay $20,000 or more in wages in a calendar quarter for agricultural labor

If any of these apply, you must register with Louisiana Works.

Step 2: Register for the accounts you need

Every new Louisiana employer needs three things before issuing the first paycheck:

1. Federal Employer Identification Number (EIN). Apply online at IRS.gov/EIN. The EIN is free and is issued immediately in most cases. You need it for federal payroll tax filings and for most Louisiana registrations.

2. Louisiana Unemployment Insurance Account Number (EAN). Apply online through the Louisiana Works registration portal at laors9.laworks.net/LaStarsRegistration. Under Louisiana Employment Security Law Rule 317, you must file within 30 days of your first payment of wages, even if you believe you are not liable.

3. Louisiana Withholding Tax Account. Register with the Louisiana Department of Revenue through geauxBiz.com. This account is used to report and remit state income tax withheld from employee wages.

If you fail to register within 30 days of your first payment of wages, you may incur penalties and interest.

Step 3: Understand federal payroll taxes

Federal payroll taxes fall into three categories: income tax withholding, FICA (Social Security and Medicare), and FUTA (federal unemployment).

Federal income tax withholding

You must withhold federal income tax from each employee’s wages based on the filing status and dollar amounts they provide on Form W-4. Withholding allowances are no longer used. Instead, the filing status and dollar amounts provided on the W-4 are used to calculate withholding.

2026 Form W-4 changes. The 2026 Form W-4 includes notable revisions following the One Big Beautiful Bill Act (OBBBA), signed into law July 4, 2025. Key changes include:

• Expanded Deductions (Step 4b): The Deductions Worksheet now includes new tax deductions, including qualified overtime compensation. Employees should review the instructions carefully to confirm eligibility before entering amounts.
• New “Exempt” Checkbox: Employees claiming exemption from withholding no longer write “Exempt” on the form. There is a dedicated checkbox between Step 4 and Step 5. Exempt status must be claimed each year by February 15.

The withholding tables are no longer in IRS Publication 15. They are now in IRS Publication 15-T, Federal Income Tax Withholding Methods.

FICA — Social Security and Medicare

2026 Social Security wage base: $184,500, up from $176,100 in 2025.

Social Security tax rate: 6.2% each for employee and employer. Maximum Social Security tax withheld from the employee and matched by the employer: $11,439.

Medicare tax rate: 1.45% each for employee and employer. There is no wage base limit for Medicare tax.

Additional Medicare tax: 0.9% withheld from any employee’s Medicare wages in excess of $200,000. The additional Medicare tax is imposed only on the employee, not the employer. Withholding begins with the pay period in which wages exceed $200,000 and continues for the rest of the calendar year.

FUTA — Federal Unemployment Tax

The Federal Unemployment Tax Act (FUTA) tax applies to the first $7,000 of each employee’s wages. The gross FUTA rate is 6.0%, but employers receive a credit of up to 5.4% for state unemployment taxes paid. The effective FUTA rate for most Louisiana employers is 0.6%.

Step 4: Understand Louisiana payroll taxes

Louisiana payroll taxes fall into two categories: state income tax withholding and unemployment insurance.

Louisiana income tax withholding

You must withhold Louisiana state income tax from each employee’s wages based on the filing status and dollar amounts provided on Form L-4. The 2026 Louisiana withholding tables are issued by the Louisiana Department of Revenue and are used in calculating state tax deductions.

Louisiana unemployment insurance (UI)

Louisiana’s unemployment insurance program is funded entirely by employer contributions. Employees do not contribute. The tax should never be deducted from employee wages.

2026 taxable wage base: Beginning January 1, 2026, Louisiana employers are liable for UI taxes only on the first $7,000 of an employee’s wages per calendar year, depending on the balance in the Louisiana Unemployment Trust Fund. The taxable wage base may vary.

New employer rate: A new employer must serve a 24-consecutive-month eligibility period during which the account can be charged with UI benefits. Until this period ends, a new employer’s rate is the weighted average rate for employers in the same industrial classification.

After eligibility: Once the eligibility period is served, the employer becomes experience-rated. The rate is based on the ratio of the employer’s reserve balance to its average annual taxable payroll.

Filing and payment deadlines

Louisiana employers must file the Employer’s Quarterly Wage & Tax Report online through the Louisiana Works portal at laworks.net/LaWatsEmployer/. Reports and tax are due by the last day of the month following the close of each calendar quarter.

All reports must be filed electronically. Interest and penalty begin the first day past the due date and are calculated at 1% per month or fraction for interest, and 1% per month, not to exceed 25%, for penalty.

Domestic employers (household help, sitters, nannies) may elect to file annually. The Domestic Employer’s Annual Wage & Tax Report is due January 31.

New hire reporting

Federal and state law require employers to report newly hired and rehired employees to the Louisiana Directory of New Hires. Reporting must be completed within 20 days of hire.

Step 5: Distinguish employees from independent contractors

One of the most common — and most expensive — mistakes new employers make is misclassifying employees as independent contractors. Louisiana law presumes that a worker is an employee unless three conditions are met:

1. The individual is free from control or direction over the performance of services, both under the contract and in fact.
2. The service is outside the usual course of the business for which the service is performed, or is performed outside all places of business of the enterprise.
3. The individual is customarily engaged in an independently established trade, occupation, profession, or business.

If any of these conditions is not met, the worker is an employee, and you must withhold and remit payroll taxes.

Penalties for misclassification

• Fines up to $2,500 per worker per instance
• Imprisonment for up to 90 days
• Prohibition from contracting with any Louisiana state agency or political subdivision for three years

Suspected misclassification fraud can be reported to Louisiana Works at 1-833-708-2866.

Step 6: Watch for SUTA dumping

SUTA dumping is a tax avoidance strategy in which employers manipulate their unemployment insurance tax rate to pay less than they owe, passing the burden to other employers. Louisiana law imposes severe penalties:

• Employers who participate may be fined up to $10,000 per incident and imprisoned up to six months
• The employer is assigned the highest rate for the violation year and the three years immediately following
• Non-employers (accountants, attorneys) who advise such schemes may be fined up to $10,000 per incident and imprisoned up to six months

Step 7: Keep your account in good standing

Several things can cause a Louisiana employer account to fall out of good standing:

• Failing to file quarterly wage and tax reports
• Failing to pay UI taxes when due
• Failing to report changes to your business (address, ownership, legal entity, FEIN)
• Failing to respond to notices from Louisiana Works

You can submit a Report of Change online through the Louisiana Works portal to notify the agency of any changes. If you are dissolving a corporation, the Secretary of State cannot issue a Certificate of Clearance until all UI taxes are paid and all wage reports are filed.

Step 8: Use a CPA or payroll provider

Payroll tax compliance is not difficult, but it is unforgiving. A single missed filing or miscalculated tax can trigger penalties, interest, and hours of administrative work to resolve.

Most new Louisiana employers use one of three approaches:

DIY payroll software. Services like Gusto, QuickBooks Payroll, or ADP handle calculations, filings, and payments for a monthly fee. This works well for businesses with straightforward payroll.

A CPA or bookkeeper. A CPA can handle payroll processing, tax filings, and compliance oversight. This is often the better choice for businesses with complex payroll, multiple entities, or multi-state employees.

A Professional Employer Organization (PEO). A PEO takes on payroll, benefits, workers’ compensation, and HR administration. The PEO becomes the employer of record for tax purposes. PEOs must register with the Louisiana Department of Insurance and Louisiana Works.

Whatever approach you choose, remember that you — not your software or your CPA — are ultimately responsible for accurate payroll tax filings and timely payments.

The bottom line

Hiring your first Louisiana employee triggers a set of obligations that do not exist when you work alone. Federal income tax withholding, FICA, FUTA, Louisiana state withholding, and Louisiana unemployment insurance all come into play — each with its own registration, filing, and payment requirements.

The steps are straightforward:

1. Determine whether you are a liable employer
2. Register for an EIN, Louisiana UI account, and Louisiana withholding account
3. Withhold federal income tax, Social Security, Medicare, and Louisiana state tax
4. Pay FUTA and Louisiana UI tax on the first $7,000 of each employee’s wages
5. Distinguish employees from independent contractors
6. File quarterly wage and tax reports on time
7. Report new hires within 20 days
8. Work with a CPA or payroll provider you trust

Get these right, and payroll becomes a routine part of running your business. Get them wrong, and you will spend months correcting them.

If you are hiring your first employee and are not sure where to start, work with a CPA who understands Louisiana payroll. The cost of professional help is small relative to the cost of getting it wrong.
