A plain-English guide to Louisville Metro occupational tax basics, OL-3 filing context, bookkeeping records, and source links for current city requirements.
This resource is educational and is not tax, payroll, or legal advice. Confirm current Louisville Metro Revenue Commission requirements with LMRC or a qualified professional.
Short answer
Louisville Metro Revenue Commission says Form OL-3 is used by entities with business nexus in Louisville/Jefferson County to file and pay occupational tax. Its current OL-3 page lists a 2.2% resident rate and 1.45% non-resident rate.
Checklist
- Confirm whether the business has Louisville/Jefferson County nexus.
- Review whether Form OL-3 applies to the business or owner activity.
- Track Louisville income, compensation, and local tax payments clearly.
- Use the Louisville tax calendar to confirm the current filing date.
- Keep payroll reports, P&L, balance sheet, and filing confirmations together.
Common mistakes
- Assuming Kentucky state registration covers Louisville occupational tax filings.
- Mixing Louisville local tax payments with state income or sales tax payments.
- Waiting until the OL-3 deadline to clean up the full year of bookkeeping.
- Ignoring employee withholding records when reviewing local tax activity.
Examples for service businesses
- A contractor doing work in Louisville should track revenue and job costs by location when local filings may apply.
- A service business with Louisville payroll should reconcile payroll reports before filing local withholding or annual returns.
- A Lexington-based business expanding into Louisville should review local nexus and bookkeeping categories before the first project.
What Form OL-3 is for
Louisville Metro Revenue Commission says Form OL-3 is used by any entity with business nexus in Louisville/Jefferson County to file and pay the occupational tax. It also notes that some individuals may need OL-3 if the full amount of occupational taxes was not withheld and remitted.
For owners, the bookkeeping goal is simple: make local revenue, compensation, and payments traceable before the return is prepared.
Current rates listed by Louisville
The current Louisville OL-3 page lists an occupational tax rate of 2.2% for the resident rate and 1.45% for the non-resident rate. Because local rules can change, always verify the rate and filing instructions on the current LMRC page before filing.
In the books, separate Louisville occupational tax from Kentucky sales tax, Kentucky withholding, federal payroll tax, and ordinary income tax estimates.
Filing date context
Louisville's OL-3 page says Form OL-3 must be hand-delivered to LMRC or postmarked by the 15th day of the fourth month after the end of the taxpayer's fiscal year. The Louisville tax calendar gives specific fiscal-year due dates.
That means a calendar-year business should not wait until April to reconcile the prior year. Close the year, review payroll, and collect source documents early.
Bookkeeping records to keep
Keep the annual profit and loss, balance sheet, payroll summaries, owner compensation details, city tax payments, and filing confirmations together. If the business operates in more than one Kentucky city, use classes, locations, or project notes only if they are maintained consistently.
A clean monthly close makes local tax review less painful because the business is not rebuilding income and wage records from bank statements.
