store.subscribe(() => {

I think you will need to do something like this:

componentDidMount() {
  this.subscribe();
}

GetFilteredData = () => {
  WithHoldTaxApi.GetFilteredData()
    .then((collection) => {
      console.log("data", collection)
      this.setState({ collection: collection })
    }
    ).catch(error => {
      throw error;
    })
}

subscribe = () => {
  store.subscribe(() => {
     console.log(store.getState())
     this.GetFilteredData();
  })
}
