When is the regulatory surcharge payment due?

Where is my invoice?

We send an email notification no later than June 15 to let your tax contact know the surcharge invoices are available. Your invoice is available after you sign into the Filing and Payment Center. Select "Make or View Payments" from the menu to see your invoice.

What if I do not make my payment on time?

Penalties are applied in stages - 5%, 10% and 20%.

Payments not made by the end of the month in which the payment is due are subject to a 5% penalty.

If your payment is not made within 45 days of the due date, there is an additional 5% due, for a total of 10%.

Payments not made within 60 days of the due date are subject to a total 20% penalty.
