Important Sales Tax Dates for October 2017

There are lots of important dates for the month of October, as both quarterly and monthly filers generally have returns and payments due within the month. In addition, annual payers in the District of Columbia do, too.

Online Marketplace Seller Voluntary Disclosure Initiative

In addition to normal due dates, it’s also important to keep the date of October 17 in mind, because that is the end of the sales tax amnesty period for Amazon and other online marketplace retailers. This two-month program allows retailers in certain states to pay back taxes with no penalties or interest. More information can be found on the Multistate Tax Commission website.

Update: The deadline for the amnesty program has been extended until November 1.
