Tips
usage
进项 is colloquial — common in everyday conversation about a household or small-business income. The opposite is 出项 (chūxiang, expenses/outgoings). For formal/written contexts use 收入 (shōurù).
register
Note the neutral tone on 项 (jìnxiang, not jìnxiàng). Pronouncing 项 with full fourth tone marks it as the unrelated word 项 'item'.
