扶養内で働く人にかなり便利
年収の壁って調べても分かりにくいことが多いですが、このアプリは収入を入れるだけで今どのくらい余裕があるか見えるので助かります。扶養内で働いている人や、年末に慌てたくない人にはかなり便利だと思います。

What's New in 税金の壁ナビ
1.8.0
November 4, 2026
・年金を受け取っている方向けに、パートの給与がいくらまでなら住民税が非課税でいられるかを、登録した年金額から計算して表示するようにしました（設定に「年金の年額」を追加）。 ・最後の壁を超えたあとも、超えた壁を下のカードに表示するようにしました。 ・「月初サマリー」が届いていなかった問題を直し、毎月1日に、年末予測で次の壁まであといくら稼げるかをお知らせします。 ・給与を入れて壁に近づいたり超えたりしたときのお知らせが、アプリを開き直さなくても、その場で届くようにしました。 ・月収などに大きな数字が入っていても、アプリが落ちないようにしました。
