Conjunctions & Linking Words

After WHEN, use the Present Simple to talk about a future event.

Even though the meaning is about the future, we normally don't use WILL directly after WHEN in this type of time clause.

Structure

When + Present Simple → will + base verb

When I go home, I will continue my new routine.

When I return to work, it will be more difficult.

I'll call you when I arrive.

Not:

❌ When I will go home, I'll continue my routine.
✅ When I go home, I'll continue my routine.

The order can change:

When I get home, I'll have a shower.

I'll have a shower when I get home.

💡 The same principle is commonly used after other time words such as:

after · before · as soon as · until

I'll eat after I finish work.
I'll text you as soon as I arrive.
