Beginning November 13, it will also support Individual Income, Partnership, Estate/Transfer, and Fiduciary tax types.

Q: Why does the billing notice show a last four-digit number that does not match my SSN?
A: Due to the confidentiality of Social Security numbers, DOTAX issues a specific tax account number for each taxpayer that does not have a Federal Identification number. Therefore, the last four-digits of the specific tax account number, issued by DOTAX, are used on the billing notices rather than the last four digits of your Social Security number.

A: Insufficient checks received by DOTAX will not be redeposited.

A: No. The Federal POA form is not accepted in lieu of the State POA form.

Q: How long does it take to get a response to a tax clearance request, after submission of the A-6 application?
A: In general, once an application is received, the normal turnaround time is approximately 10-15 business days. However, walk-in customers after waiting for the tax clearance process to be completed, by the Department staff, would normally receive a response at that time.

A: First, you need to download an Adobe Reader from the Adobe website. The viewer is free. Follow the instructions to install the viewer and you will then be able to view and print our pdf files.

A: You can select a box or checkbox on a form for entry either by clicking on it with your mouse or hitting the tab key. The tab key will take you to the next predefined box on the form where you can begin entering information.

If your computer does run out of memory and “crashes” all your entries may be lost.
