Redknapp has said that the FA, who appointed Roy Hodgson to the job, were forced to look elsewhere due to the large buyout clause in his Spurs deal.
"I wouldn't take [the England job] now, no, not now, not in the future," Redknapp told the Evening Standard. "That was my time, really, if I was going to get it.
"Last year, there were a lot of things that went against me surrounding that massive contractual clause. People will always deny that is the reason, the FA couldn't say that and I won't say, but it didn't help me.
"I had such a badly loaded contract it was crazy, in Tottenham's favour. That's what you get for not reading your contract properly. It was a massive amount that someone would have had to pay to get me out of it."
Redknapp's current side QPR are seven points adrift of safety at the bottom of the Premier League.
