In Sweden, Tapani played in the Swedish Women's Hockey League (SDHL) with Linköping HC Dam.

Regarding the situation, Tapani stated, "I’m not commenting on the discussions [with TPS] or the way this came to be, but combining the two sports didn’t fit when there were too many overlapping games.

[10][11] Tapani trained with several men's professional ice hockey players during the extended pause between the 2019–20 and 2020–21 seasons due to COVID-19.

[17][18][19][20][21] At the 2017 IIHF Women's World Championship, she was Finland's leading scorer and ranked fifth for scoring in the tournament overall with 3 goals and 6 assists for 9 points in 5 games.

[23] Though Finland suffered their worst Olympic placement in team history, finishing in fifth place, Tapani saw individual success and tied teammate Riikka Välilä for third rank on the Finnish scoring list, with 1 goal and 4 assists for 5 points in six games.

[24] In the women's ice hockey tournament at the 2018 Winter Olympics in Pyeongchang, Finland won bronze and Tapani finished fourth in the team's scoring ranks, with 2 goals and 3 assists for 5 points in six games.

[25] The women's ice hockey tournament at the 2022 Winter Olympics in Beijing saw Tapani take another step in offensive production – she ranked first on the team in scoring with 6 goals and 2 assists for 8 points in seven games – and led Finland to another bronze medal victory.

[32][33] Tapani has played the entirety of her senior club career (as of 2024) with Raision Nuorisokiekko and contributed to Finnish Championship victories in 2011, 2017, and 2023.

[46] Three years later, she participated in the 2012 World Junior Ringette Championships, at which Finland iced one team, and took home a silver medal.
