"The budget for that project is too low."

Translation: 那个项目的预算太低。

Is there any reason 'le' isn't added at the end of this sentence?

[Keith_APP]

In this sentence we can add 了 to express an emphasised emotion e.g.surprised, disapproval, disappointment. But if it is not necessary to do so, it is not needed. Then 太 remains the adverb Too and the statement is relatively emotionally neutral.

I wanted to ask as well

[MatthewEpp5]

I was wondering the same thing. Thank you for the explanation, Keith!

I was looking for the 了 too. But why not 太低的?
