The 30-year-old, who has another year remaining on his current deal at the Bundesliga side, has been linked with a switch to Anfield to replace Luis Suarez, should the Uruguayan head to Barcelona after talks were held between the two clubs.
Huntelaar joined Schalke from AC Milan in 2010 after a disappointing spell at Real Madrid, and he hit 14 goals in 21 appearances for the German outfit last season.
Huntelaar is currently representing Holland at the World Cup, with Costa Rica awaiting in the quarter-finals, but he refused to be drawn on the reports as he plans some time off after the tournament.
"Regarding the rumours about Liverpool it would only be fair to speak to Schalke first," he told De Telegraaf.
"I've talked with Schalke about an extension for a while. After the World Cup I am having a holiday. Then I will speak to them again.
"With my agent, I now do not talk about the interest from clubs. I focus on the tournament."
