A Practical Tax-Season Guide for Small Business Owners in Louisiana

Sean Thomas

Quick Summary: As tax season approaches in Louisiana, small business owners should begin by organizing financial records, confirming that payroll and sales tax filings are up to date, and reviewing tax obligations specific to their business entity. It’s also essential to understand what your LLC, S corporation, partnership, or small corporation must file. Finally, meet with a CPA early—before deadlines arrive—to avoid surprises and keep your business on track.

At South & Thomas LLC in Slidell, LA, we work closely with small business owners across the Northshore and Southeast Louisiana to reduce tax stress and improve preparedness. Whether you're navigating annual filings, estimated payments, or entity-specific requirements, a little upfront planning can make a big difference.

Get Organized Early

The first step in a smooth tax season is gathering and organizing your documents. This includes income statements, expense records, bank and credit card statements, payroll summaries, mileage logs, loan documents, asset purchase records, and any year-end reporting from vendors (such as 1099s). Keeping this information in one place helps your CPA clearly identify deductions, ensure accuracy, and minimize back-and-forth during preparation.

Understand Your Entity’s Obligations

Louisiana businesses face different tax requirements depending on their structure. Here's a plain‑language breakdown:

• LLCs: Single‑member LLCs typically file as sole proprietorships unless they elect otherwise. Multi-member LLCs usually file partnership returns. Louisiana also requires an annual report and state-level filings based on your classification.
• S Corporations: S corps must file a federal 1120‑S and a Louisiana CIFT‑620. Owners must ensure reasonable compensation is documented and payroll taxes are correctly handled.
• Partnerships: Partnerships file federal Form 1065 and issue K‑1s to partners. Louisiana returns are required as well, and accurate allocation of income, losses, and distributions is essential.
• Small Corporations: C corporations must file federal Form 1120 and a Louisiana corporate income and franchise tax return. Keeping accurate bookkeeping and tracking retained earnings helps avoid complications at year-end.

If you’re unsure how your business is classified or which forms apply to you, now is the perfect time to meet with a CPA for clarification and planning.

Review Payroll, Sales Tax, and Local Requirements

Louisiana has unique state and parish-level tax rules. Before filing your annual return, confirm that:

• Payroll filings and W‑2/W‑3 submissions are completed
• Independent contractor 1099s are properly issued
• Sales tax filings (state and parish) are current
• Local occupational license taxes are up to date

Missed filings can cause delays when preparing your return—and may lead to penalties. Reviewing these obligations ahead of time helps avoid last-minute issues.

Meet With a CPA Before Deadlines

A proactive conversation with a CPA can uncover tax-saving opportunities and prevent errors. Whether you need help projecting estimated taxes, planning deductions, or understanding Louisiana filing timelines, an early meeting gives you time to make adjustments before the year closes.
