As another commenter pointed out this is a US based site and I would always assume it’s pretax salary. Even the Europeans who mention salaries will usually clarify if it is post tax.

My comment was about: In some countries your after-tax salary does not depend on your spouse. In those countries, people are taxed as individuals, not as a family unit.

Unless you are married and file taxes separately. Another reason why salaries are referred to in pre-tax terms.
