When I try to select "Pay & File" or "Mark as Paid" for past payroll taxes, I get an error saying "No taxes due this period"? How do I remove these?

My main goal is to ensure the error message you encountered gets resolved, Twylag. 

When you experience any error when paying, filing, or marking payroll taxes as paid, this needs to be further investigated to determine the main cause of the issue.

Since we need to view your Payroll tax page, I recommend contacting our phone or chat support team. They have tools to securely access your account and provide solutions to fix the problem and ensure your taxes are recorded accurately. I've included the steps to contact support below.  

1. Go to the Help (?) icon at the top.
2. On the Assistant tab, click Talk to a Human.
3. Enter your concern in the Type Something field, then click the Send icon.
4. Click on I still need a human.
5. Select Get help from a human.
6. You can either select Chat with us or Have us call you.
