Release: 2025-10.44.0
Update: November 18, 2025
United States
Connecticut
Paid Family Leave Insurance (FLI) - effective January 1, 2026
Previously, Connecticut Paid Leave was calculated based on regular wages, with a dependency on State Unemployment (SUTA) wages being defined. Connecticut Paid Leave taxable wages are now based on SUTA gross wages.
Kentucky
Unemployment Tax – effective April 1, 2025
The Kentucky State Unemployment Tax default rate increased from 2.625% to 2.7%. The wage base remains $11,700.
City OLF – effective September 12, 2025
The engine now considers both period withheld and year-to-date withheld values when determining if an employee has reached the Kentucky City OLF wage base.
- If a period withheld value is present, the engine will continue to use it.
- If the period withheld value is zero, the engine will fall back to the year-to-date withheld amount.
Previously, the engine only used the period withheld to determine if the employee reached the wage base.
Bardwell OLF – effective July 1, 2025
The OLF rate increased from 0.5% to 1%.
Crittenden County OLF - effective July 1, 2025
The OLF rate increased from 0.5% to 1.5%.
Grace Commercial Park TIF – effective October 1, 2019
Effective October 1, 2019, Graves County has established a 1% Tax Increment Financing (TIF) assessment. While the tax went into effect October 1, 2019, the first building on the lot was completed in September 2023. The tax is 1% of all wages and compensation for work performed within the Grace Commercial Park Development Area by every resident and nonresident employee.
This TIF tax "stacks" with the Graves County OLF tax, resulting in a total stacked rate of 2%.
Marion OLF – effective July 1, 2025
The Occupational License Fee rate increased from 0.75% to 1.5%.
Powell County – effective July 1, 2025
The Occupational License Fee rate increased from 1.25% to 1.75%.
Maryland
Ann Arundel County supplemental calculation correction – effective January 1, 2025
Supplemental-only payroll calculation logic was updated to align to the 2025 Maryland Withholding Guide. Previously, the engine calculated Anne Arundel and Frederick County withholding for supplemental-only paychecks based on the bracket-based logic.
The tax engine will now apply a flat combined rate using the following for supplemental-only payroll runs:
- The highest state tax rate (6.5%)
- The highest local county rate (3.20%)
This results in a combined withholding rate of 9.7%.
This change affects only supplemental-only payroll calculations. It does not impact calculations that include regular wages (alone or with supplemental wages). Only lump-sum calculations using supplemental-only wages will be updated.
Fredrick County supplemental calculation correction – effective September 12, 2025
Supplemental-only payroll calculation logic was updated to align to the 2025 Maryland Withholding Guide. Previously, the engine calculated Anne Arundel and Frederick County withholding for supplemental-only paychecks based on the bracket-based logic.
The tax engine will now apply a flat combined rate using the following for supplemental-only payroll runs:
- The highest state tax rate (6.5%)
- The highest local county rate (3.20%)
This results in a combined withholding rate of 9.7%.
This change affects only supplemental-only payroll calculations. It does not impact calculations that include regular wages (alone or with supplemental wages). Only lump-sum calculations using supplemental-only wages will be updated.
Fredrick County Tax – effective January 1, 2025
The engine will calculate Frederick County income tax using the applicable tax brackets in the 2025 Maryland Withholding Guide (page 9) instead of always applying the highest county rate. This change applies to regular and regular + supplemental payroll runs. Supplemental-only calculations remain unaffected.
As a reminder, the state and county taxes are returned as a combined amount under the Maryland State Tax. The portion of the tax from the state itself is unaffected by this change.
