The answer ism yes, you definitely can. Here we will describe the general procedure of applying for Form 6166. Please note that there are a lot of specific requirements depending on the entity type. But the general steps will be as follows:

- You will need to properly complete Form 8802 and submit it to the IRS. The IRS provides detailed instructions on how to fill out this form.

- Some types of entities will have to submit additional documents along with form 8802. For example, an S-corporation will need to submit the information about all shareholders, including each shareholder's name, address, and social security number. You will find information about additional document requirements in the instructions to Form 8802.

- Before submitting Form 8802, you will need to pay the IRS fee which is $85 at the present time.

- Then you can submit the application by fax or by mail.

- Your application will be stored in the IRS computer until its turn to be reviewed. Usually it takes between four and six weeks. If you call the IRS about the status of application before your turn comes, the answer will be that they do not have any information about your application.

- Then, the IRS will start to review your application. When it happens, a standard letter is generated by the IRS computer and mailed to you saying that the IRS received your application and it is being reviewed.

- If you completed Form 8802 correctly and provided all required supporting documents, your application will be approved approximately within 30-45 days from the beginning of the reviewing process (not from the day you submitted the application by fax or your application was received by the IRS by mail)

- If the application is not approved, you will get a letter with request for additional information or a letter stating that your application has been rejected. This correspondence can take a few more weeks. This is why it is essential to do everything right from the very beginning.
