Voting for Isaac Newton and Aveland wards will be on the same day as a by-election for Colsterworth Rural electoral division of Lincolnshire County Council.
Candidates can be nominated from Friday 21 January, and nomination papers must be signed by a proposer and seconder who need to be local government electors for the relevant ward or division.
SKDC Chief Executive and Returning Officer for the district, Karen Bradford, said: "Councillors make a real difference to their communities and these elections will give people the chance to put themselves forward to help decide local issues.
"If you are interested in standing, please get in touch with our Elections team who can explain the process and assist with all aspects of the process, including the paperwork, campaigning and count arrangements."
