Once a lock-in rate is effective, an employer cannot decrease withholding unless approved by the IRS.
How Often Can I Revise My Withholding? You can submit a revised Form W-4 at any time during the year. If your circumstances change—for instance, if you get married, have a child, or start a second job—you can adjust your withholding as needed.
You cannot amend Form NYS-45 online. If you need to amend your return, file paper Form NYS-45-X, Amended Quarterly Combined Withholding, Wage Reporting, and Unemployment Insurance Return.
IRS guidance states an employee has the right to make changes to their Form W-4 as often as they would like, and you, as the employer, need to make those changes.
Thus, claiming ``0'' results in the smallest paycheck, but a larger tax refund at tax time. The larger the number (ie 1, 2, 3, etc...) will result in larger paychecks, but will reduce tax withholdings which may result in a smaller tax refund or owing at tax time.
Businesses that violate employment tax laws may be subject to: Monetary penalties. Interest on back taxes. Liens against property.
Take advantage of the line for extra withholding. If you want to have a specific number of extra dollars withheld from each check for taxes, you can put that on line 4(c).
If the amount under/over withheld is deemed too excessive, the IRS can send a lock-in letter notifying the employer how to adjust withholding regardless of the employee's W4 requests. If a W-4 error is caught before filing, individuals can correct this relatively easily by refiling a W-4 with their employer.
