Seven players, including Lee Collins, will be leaving the club after the expiry of their contracts.
John-Joe O'Toole and Chris Hackett have been transfer-listed while Shwan Jalal, Billy Bodin and Tom Newey may yet be offered new deals.
Three loanees, including Kaid Mohamed, return to their parent clubs leaving twelve players currently under contract and coming back to Sixfields in 2015/16.
Nine of those started Saturday's game at Wycombe and clearly form the backbone of the managers' team while the goalkeeping area could be his first port of call in the transfer market with Matt Duke allowed to leave.
Wilder spoke to the official NTFC website to explain his decisions.
