Carrie Underwood and Paisley announced the nominations at the Country Music Hall of Fame.
Atkins' nominations include song of the year and video of the year for "Watching You" and album of the year for "If You're Going through Hell," which he also co-produced.
The singer, who has had four straight No. 1 singles, won best new male vocalist at last year's ACMs.
Paisley is nominated for male vocalist, album of the year for "5th Gear," video of the year for "Online," and entertainer of the year.
"This is one of the days where you're glad you got up early," said Paisley, who read the list with Underwood on CBS' "The Early Show."
He added that his confidence as an entertainer has grown in recent years as he's headlined tours and bolstered his stage shows.
"I feel a little more comfortable and not as guilty" Paisley said of the entertainer nomination. "That doesn't mean that I feel that I deserve it, it just means I feel like I've earned a place."
Miranda Lambert and Taylor Swift received three nominations apiece including album of the year, Lambert for "Crazy Ex-Girlfriend" and Swift for "Taylor Swift."
"I poured my heart into this album, and the great response makes it that much better," Lambert said.
Underwood said the ACM awards hold special meaning for her because they were the "first major awards that I started winning."
"And they're in Vegas," she added with a laugh, "so they always stand out as being a good time and just getting together and celebrating country music."
