在英语中，询问何时发放钱款通常使用以下表达：

"When do you pay the salary？"

"Which date do you pay the salary？"

"We usually pay the salary on the 5th."

"When will you get paid？"

"Our salaries are always delayed to be paid."

这些句子可以用来询问工资或报酬的支付时间。如果你需要了解具体的支付安排，你可以进一步询问，例如：

"Can you tell me the exact date of payment？"

"Is there a set schedule for when I will receive my money？"
