Lookback Period


Withholding filing frequencies are determined using a “lookback period,” which is the fiscal year from July 1 to June 30 immediately preceding the calendar year for which the period is being determined.

For instance, the lookback period for calendar year 2024 withholding is July 1, 2022 through June 30, 2023. The Division of Revenue looks at this time annually to determine how much tax you’ve reported. The amount you’ve reported determines whether you will have to remit your withholding monthly, quarterly, or 8th monthly.

 

The withholding thresholds for 2023 are listed below:

$5,530.00 or less remits Quarterly
$5,530.01 to $30,740.00 remits Monthly
$30,740.01 and greater remits 8th Monthly

 

The withholding thresholds for 2024 are listed below:

$5,700.00 or less remits Quarterly
$5,700.01 to $31,650.00 remits Monthly
$31,650.01 and greater remits 8th Monthly

 

Threshold updates for 2025 will be posted here when they become available.

 

Annual Thresholds for previous years can be seen on the Annual Threshold Updates Chart.

 

PLEASE NOTE: Those with no prior record of withholding will file on a monthly basis until the next “lookback period”.
