Now TaxACT.

Danica Patrick's sponsor lineup for the 2016 Sprint Cup Series season just continues to grow.

The latest addition came on Friday at Martinsville Speedway where Patrick and Stewart-Haas Racing officials announced that TaxAct -- a company specializing in tax preparation solutions -- will join Nature's Bakery and Aspen Dental as a primary sponsor on Patrick's No. 10 Chevrolet for four races next year, with associate sponsorship in all other races.

Patrick's newly announced deal with TaxAct is part of a multi-year agreement.

Patrick's relationship with TaxAct is not a new one, however, as the company has been a primary sponsor on her car for two points races and the non-points-paying Sprint Unlimited in 2015.

Nature's Bakery, a company based in Reno, Nev., will be Patrick's primary sponsor for 28 races next season as part of a multi-year agreement announced in August.

GoDaddy.com, Patrick's primary sponsor since she joined the Sprint Cup Series full time in 2013, announced in April that it would not return to NASCAR next season, citing plans to focus on global expansion instead of domestic growth.

Aspen Dental, which has been a primary sponsor for Patrick in two races this season, will become her primary sponsor for four races per season starting in 2016 as part of a multi-year contract agreement announced in September.

Patrick, one of the Sprint Cup Series' most popular and marketable drivers, has two top-10 finishes in 32 starts this season.

A native of Joliet, Ill., Patrick scored a career-best finish of sixth last September at Atlanta Motor Speedway.
