The Dutchman, who recently guided Ajax to their fourth consecutive Eredivisie title, has been heavily linked with a move to White Hart Lane in recent weeks.
While he admits that he does not want to hold talks before the end of the season, De Boer has suggested that he would be keen on joining Spurs this summer.
"I want to add something to a club, build something. - I won't be talking to other clubs til after May 3," the 43-year-old told NOS.
"After the last match on May 3 I will think about this possibility. I will have talks and will listen to their offer. After that I will decide on how I feel."
De Boer was appointed manager of Ajax in 2010.
