IF + present simple or present continuous (2025)

I’m just wondering when I can use if with the present continuous together. Are both tenses possible in the examples given bellow?

“If you’re helping me out here, I’ll…” / “If you help me out here, I’ll...”

“If you’re looking for Ms. …, she’s out sick today” / “If you look for Ms…, she’s out sick today”

“If you’re asking me, I don’t believe him.” / “I you ask me, I don’t believe him”

They are all possible, but there may be some change of meaning depending on the tense you choose.

If you help me out ...
This is talking about future action - helping in the future.
If you are helping me out ...
This is talking about current action, or at least an existing commitment to help.

If you look for Ms ...
You have not begun to look for her yet. This is talking about looking in the future.
If you are looking for Ms ...
You seem to be looking for her. This is talking about looking in the present.

The third example is a little different.
If you ask me ...
Taken literally, this is talking about possible future asking.
But it is a standard expression that introduces the speaker's opinion, without there being any asking on the part of the listener.
If you are asking me ...
This is similar to "If you ask me ..."

Can I say about this pair of sentences:

If you run a temperature you should not be at school.
This is talking about future action - helping in the future.
If you are running a temperature you should not be at school.*
This is talking about current action.

Can I conclude that when I use "if + present continuous" I refer to a current action?

I agree with you, with one small correction. "If you run" introduces a general rule, which will apply to the future (or to the past, or to the present, but not to the specific case being discussed in the present). "If you're running" would be said to a specific person who right now is running a temperature and thus should either not go to or should not be at school.

But then...

Can I conclude that when I use "if + present continuous" I refer to a current action?

I would really advise against making these rules so emphatically in regards to aspect, because the meanings of the different verbal aspects vary from verb to verb. In other words:

If you're sick, then you shouldn't go to school today / be in school right now.
If you've got a fever, then you shouldn't go to school today / be in school right now.

With these different verbs, the present simple refers to what I think you mean by "current action."

I would say, yes, in general, the present continuous will always refer to an ongoing action that is particularly relevant right here and now, but the inverse is not true ("current actions" aren't always expressed by the present continuous).

I didn't know that "If you run" can apply to the past. I thought that I would have to use the present perfect for that purpose. And it is interesting to learn that "If you run" can also apply to the present.

So, this is true in general, but there could be some unforeseen exceptions.

As a general rule (zero-conditional, I believe). For instance, "The earth revolves around the sun" refers to what the earth was doing yesterday, what it's doing today, and what it'll do tomorrow. Here's a dialogue:

A: I had to beg Alex to go home yesterday. He was sitting at his desk, constantly coughing and sniffling. He said he just wanted to make sure the project got finished on time, but he could've taken us all out with the flu.
B: That's dumb of him. If you're sick, you stay home. Everybody knows that.
