If you do not want taxes withheld, you should notify VRS, using the Request for Income Tax Withholding form VRS-15 30kb. If you decide not to have taxes withheld, however, you may be responsible for paying estimated taxes, and there may be tax penalties if your withholding and estimated tax payments are not sufficient.
You may also need to change your withholding if you have married, divorced or had other changes affecting your tax status during the past year.
You can change the withholding amount at any time during the year by filing a new VRS-15 form. If you are not claiming residence status in Virginia and will not file income taxes with the Commonwealth of Virginia, you must complete the VRS-15 form and mark the block indicating "non-resident" status for state taxes.
