Polite Ways to Say "Busy"
The most common polite version is "I'm a bit tied up right now" — the softener "a bit" and the idiom "tied up" make it about the moment, not about the person asking. In writing, "My schedule is fully committed" does the same job more formally.
The most common way
You can't talk or take something on at this moment, said in a way that sounds temporary and friendly rather than like a brush-off.
How to say it: Say "tied up" as one unit — the /d/ links straight into "up", so it sounds like "tie-dup"; put the stress on "tied" and keep "a bit" quick and low.
Other ways to say it
- formal

When to use it: In email or on the phone with clients, senior colleagues or anyone you want to keep at a formal distance.

Common mistakes
I am very busy, so I cannot.→ I'm afraid I'm tied up at the moment — could we do it a little later?A bare "I am very busy" with "so I cannot" sounds curt; adding "I'm afraid" and an alternative keeps it warm.
I have no time for you.→ I don't have much time today, I'm afraid."No time for you" sounds like a personal rejection rather than a full diary.
I'm busy now, call me later.→ I'm tied up right now — could I call you back?The bare imperative "call me later" sounds like an order; a question turns it into a request.
