Payroll Compliance in Oklahoma: Avoid These Common Employer Mistakes

Staying compliant with payroll laws in Oklahoma isn't optional. For small business owners, payroll compliance mistakes can lead to IRS penalties, state audits, and employee dissatisfaction. At Boulanger CPA, we help Oklahoma businesses avoid those risks by providing CPA-led payroll services that are accurate, compliant, and headache-free.

This post will walk you through the most common payroll mistakes we see among Oklahoma business owners — and how to fix or avoid them altogether.

1. Misclassifying Employees and Independent Contractors

What goes wrong:

• Paying a full-time worker as a 1099 contractor
• Avoiding payroll taxes by labeling employees as contractors

Why it matters: Misclassification can trigger IRS audits, state back taxes, and penalties — plus potential liability for unpaid benefits.

How to avoid it:

• Use the IRS's common law test or Form SS-8 to determine classification
• When in doubt, classify as W-2 and withhold payroll taxes
• Let a CPA review your workforce structure

2. Missing or Late Payroll Tax Deposits

Late or missing federal or state payroll deposits are one of the fastest ways to get in trouble with the IRS or the Oklahoma Tax Commission.

Avoid it by:

• Using automated deposit scheduling through your payroll provider
• Working with a CPA firm that ensures tax remittance deadlines are met
• Reviewing your federal and state deposit calendar quarterly

3. Failing to File Quarterly and Year-End Returns

Oklahoma employers must file:

• Federal: Form 941 (quarterly), Form 940 (annually)
• State: OESC reports and Oklahoma Withholding Tax returns

Solution:

• Confirm your payroll provider (or CPA) handles both federal and state filings
• Get proof of filing confirmations every quarter
• Maintain digital and hard copy archives of all reports

4. Not Issuing W-2s and 1099s on Time

Federal and Oklahoma deadlines for W-2s and 1099s are January 31.

Fix it by:

• Keeping contractor and employee info up to date all year
• Using software or a CPA-led service that automatically handles year-end filings
• Double-checking totals and EINs well before the deadline

5. Not Keeping Up with Oklahoma Wage & Hour Rules

Where businesses slip up:

• Miscalculating overtime for salaried employees
• Delaying final paychecks after termination
• Forgetting Oklahoma's pay frequency laws

Stay compliant by:

• Documenting your pay policies clearly
• Auditing payroll calculations quarterly
• Asking your CPA for a compliance check

6. Using Outdated Payroll Software or DIY Tools

The risk:

• Errors in tax rates or deadlines
• No compliance safeguards
• No one to catch or fix mistakes

What we recommend:

• Upgrade to a CPA-led payroll service that stays current with both IRS and Oklahoma rules
• Eliminate manual entries and guesswork
• Get real support when you need it
