Does a Muslim wife have to share her salary?

The husband provides

Islam places the duty of financial support (nafaqah) on the husband:

This applies even if the wife earns more than he does. When Hind complained that her husband Abu Sufyan didn't give enough for her and her children, the Prophet ﷺ told her to take what was reasonably enough for them (Sahih al-Bukhari 5364). Providing for the children is also his duty. See Who has to provide for children in Islam?

Her money is hers

• Her salary, savings, inheritance and mahr all belong to her. See What is mahr and how much should it be?
• Her husband may not take any of it without her free consent.
• She pays her own zakat on her wealth if it reaches the threshold. See Does a husband have to pay his wife's zakat?

When she chooses to help

Many wives do contribute, especially when living costs are high. That's a beautiful choice, not a duty, and she is rewarded for it. When Zaynab, the wife of Abdullah ibn Mas'ud, asked about spending on her husband, the Prophet ﷺ said she would get two rewards: one for kinship and one for charity (Sahih al-Bukhari 1466). A husband who accepts her help should show gratitude and never treat it as something he's owed.

Agreements and fairness

Some scholars say that if the wife's job takes time away from the home, the couple may agree that she contributes part of her income, ideally discussed before marriage or written as a marriage condition. Scholars differ on how far a husband can make his permission for her work conditional on this. The safest path is open, kind discussion: decide together who pays for what, whether to keep a joint account for shared bills, and how savings are handled.
