Kosovo, chasing their first World Cup appearance, finished second in their qualifying group with 11 points to secure a berth in March's European playoffs.
They will now face Slovakia, with the winner then playing either Turkey or Romania in a playoff final with a World Cup spot up for grabs.
Caretaker Prime Minister Albin Kurti said his government would offer 500,000 euros ($579,700) bonus to the team if they beat Slovakia.
"Second, in the event of qualification for the World Cup, we commit to an additional one million euros reward," Kurti said during a televised cabinet meeting.
"Let's go Kosovo, always with you," he added.
Kosovo became a UEFA and FIFA member in 2016 after declaring independence from Serbia in 2008.
