Yes. We use a Secure Socket Layer (SSL) certificate to encrypt traffic from your device to our servers.

Security codes contain six characters that you will receive by email or text the first time you log in to myVTax, or when you log in from a new browser or device. This is a method of dual factor authentication to help protect your account's security.

Once you have received a security code you can log into myVTax using your username, password, and security code. When logging in you are asked if you want to trust this browser or not. If you select to trust the browser, you will not have to acquire a new security code unless you log into myVTax from a new browser or device.

Important: The button to trust this browser uses cookies to store your preference on your computer. If you delete your browser's cookies or your browser does not allow for cookies to be saved, you will not be able to trust your browser. Many companies clear browser cookies on office computers nightly, or do not allow them to be saved at all. If this is true for your company and you cannot set an exception for the Vermont Department of Taxes, you may need to acquire a new security code on each log in.

There are a few steps to take if you are not receiving your security code:

Important: To protect the safety of myVTax accounts, Vermont Department of Taxes staff will not change email addresses or phone numbers over the phone for a myVTax account. It is important to confirm you are entering the correct email address or phone number when you register for your account.

• Give the security code a couple minutes to arrive via email or text, especially if you are trying to get the code emailed to a business email address. Many companies have firewalls that delay the receipt of incoming emails to ensure their safety.
• Make sure that the security code has not ended up in your email spam or junk folder.
• If this is the first time you are trying to receive a security code, make sure that you entered the correct email address when you signed up for myVTax.
• If all else fails and you are unable to receive a security code even after taking the steps above and contacting the Department for help, you can file a return without logging into your account. We recommend this if a filing due date is soon and you want to make sure your return is filed on time.

The button to trust this browser uses cookies to store your preference on your computer. If you delete your browser's cookies or your browser does not allow for cookies to be saved, you will not be able to trust your browser.

The best time to submit a PTT return is after the closing. The return can be saved and accessed later before submitting to the town. Once the return is ready for submission to the town, you can check the box on the final step that indicates the return is ready to be reviewed by a town clerk.

Important: Once you've submitted the return to the town clerk, you cannot make additional alterations without the intervention of the town.

Once the return is submitted to the town clerk, users cannot adjust the return without the town releasing the return to the taxpayer. The town clerk can achieve this by editing the return from their town queue, unchecking the box on the final step that indicates the return is ready for town clerk review, and saving the return. This will allow the preparer to edit the return and re-check that box to send the return back to the town.

When you file a return, one of the steps asks you to print a pre-filled voucher prior to submission. You can also print a pre-filled voucher from the activity section when you access a saved return. These links can be used both prior to sending and after sending to the Town Clerk to print a voucher.

The PTT and LGT returns allow preparers to navigate to the next step even when required information is missing. To do this, you must click the check box at the bottom of the screen for a step where you are unable to complete all required fields. You cannot submit the return without going back and completing the required fields and unchecking that box to indicate you are finished with that section.

Important: Once you have completed all required fields on a step you must also uncheck the box to submit the return.

It is okay if the deed takes longer to record than 60 days. This question is asked to help town clerks manage their workflow and expectations surrounding recordings.

Only one SPAN number can be entered per return. You should enter the information for the "parent" parcel (largest parcel or parcel with homestead) on the main return, then use the system's attachment functionality to include information on the additional parcel(s).

You must bring the paper copy of the return printed from myVTax and evidence of the transfer (ex: deed, bill of sale, etc.). The town clerk will have a record of the return in myVTax and can access it with the information shown on the printed copy.

There is no longer a $5 fee for electronic filing with the Department. Filing on myVTax is free.

The Commissioner's Certificate number is the letter ID printed on the top right corner of the certificate. This ID will consist of ten numbers.

When you file a return, one of the steps asks you to print a pre-filled voucher prior to submission. You can also print a pre-filled voucher from the activity section when you access a saved return. These links can be used to print a voucher both prior to sending and after sending the return to the Town Clerk.

An appeal is appropriate if:

• you believe the facts used by the Department are incorrect
• you think the Department is applying a law or regulation incorrectly

An appeal is not appropriate if:

• You are only concerned that you cannot afford to pay the amount you owe. If you cannot pay what you owe, please contact the Department at (802) 828-2518 to set up a payment plan.

If you have received a notice of intent to assess, you can dispute the Department's findings before an official notice of assessment is issued. Disputing a notice of intent to assess is meant to be a more informal process than an appeal. When completing a dispute on myVTax please make sure to enter the letter ID associated with your notice of intent to assess.

Disputing your notice of intent to assess is appropriate if:

Disputing your notice of intent to assess is not appropriate if:

When should I appeal?

If you've received a notice of refund reduction, you have the right to appeal. Appeals must be received within 60 days of the mailing of the notice. If you received a refund check for less than you expected, you can still cash that refund without forfeiting your right to appeal. When appealing on myVTax please make sure to enter the letter ID associated with your notice of refund reduction.

An appeal is appropriate if:

• you believe the facts used by the Department are incorrect.
• you think the Department is applying a law or regulation incorrectly.

What should I submit for my appeal?

When submitting your appeal, it is important to be as specific and clear in your position as possible. The Department requires you to attach documentation supporting your position.

• If you believe the facts the Department is using are incorrect, you should submit documents or records as evidence to support the facts you believe are correct.
• If you believe the Department is not correctly applying a law or regulation, you should review the laws or regulations involved in the issue, and submit a response that clearly outlines your position and lists the laws and regulations that you are referencing.
• Regardless of why you are appealing, you should always provide a full list of issues you disagree with and why.
• If there is a best time or method to contact you, provide that information in your appeal.

To learn how to submit documents for an appeal, please see the frequently asked question, How do I Respond to Correspondence?

What should I expect from my appeal?

Once the Department receives your appeal, you will receive an acknowledgement letter that your appeal was received and will be reviewed.

Once the Department has reviewed your appeal, it may:

• Adjust or eliminate its reduction
• Request additional information from you to help make its decision
• Offer you a settlement to resolve the case
• Send a letter informing you of why the reduction will not be adjusted, and offer you an opportunity to challenge that determination or withdraw your appeal
• Ask to schedule a prehearing meeting to discuss the case
• Schedule you for a Commissioner's hearing.

The time it takes the Department to review appeal cases varies depending on the complexity and facts of the case. We strive to respond to all appeals timely. Generally, you can expect to hear from us within 60 days from when you file your appeal.

If you've received a notice of intent to reduce refund, you can dispute the Department's findings before an official notice of refund reduction is issued. Disputing a notice of intent to reduce refund is meant to be a more informal process than an appeal.

Once we have completed our review, one of three actions will occur:

• The Department will send a letter informing you why the assessment will not be adjusted. You will be given an opportunity to appeal the Department's decision within 60 days.

The Department will not begin collection action while an intended assessment is disputed, but if you are not successful in your dispute, penalty and interest may be included in the ultimate assessment.
