Millions of taxpayers are still rushing around gathering receipts, and grappling with paperwork, days before Tuesday's filing deadline. Millions of others have already received refunds.
Still, filers in both groups can take advantage of this year's basket of Tax Day rewards, including free pizza and cookies and hotel and getaway discounts. CNBC took a look at some of what's being offered to help soothe the IRS jitters.
On Tax Day (April 17 this year), Great American Cookies will be giving away a free cookie to anyone who stops at one of their participating stores. This year's treat is Cookies & Cream.

Grimaldi's Pizzeria locations around the country are offering 16" traditional cheese pizzas for $10.40 (inspired by the individual filing form).
