How to decline a meeting politely: 3 templates

To decline a meeting politely, thank the person, say clearly that you can't attend, and offer something in its place: another time, a colleague who can go, or your input by email. A reason helps but can be short: "I'm with a client at that time." Reply as soon as you know, not on the day.

The messages

Copy a message, then replace the parts in [square brackets] with your own details.

Formal

For a client, someone senior, or an external invitation.

Dear [Name],

Thank you for the invitation. Unfortunately, I have a prior commitment on [Thursday at 3 p.m.] and won't be able to attend.

Would [Friday morning] work instead? Alternatively, [Colleague] could join on my behalf.

Kind regards,
[Your name]

Neutral

For a colleague or an internal meeting.

Hi [Name], thanks for the invite. I can't make [Thursday at 3], I'm with a client. Could you send me the notes afterwards? I'm happy to share my input on [the budget] by email before the meeting.

Casual

For a regular team meeting, when missing one is normal.

Can't make it this time, sorry! Could you share the notes or the recording? I'll catch up after.

Why this works

The "no" is clear. "I won't be able to attend" leaves no doubt. "I'll try to come" when you know you can't is worse than a polite no.
"Unfortunately" and "prior commitment" do the softening. You don't need to explain the other commitment in a formal message.
There's always an offer. Another time, a colleague or your written input shows you care about the meeting's goal, not just your calendar.
"I can't make it" is the natural phrase. It's polite and common at every level. "I can't come" is fine too; "I won't go" sounds like a refusal.

Before you say no: ask for the agenda

Sometimes the problem isn't the time, it's that you don't know why you're invited. This message is polite and saves everyone an hour:

Hi [Name], thanks for the invite. Before I accept, could you share the agenda? I want to check whether I'm the right person to join, or whether [Colleague] would be more useful.

If you use the "Decline" button in your calendar, add a short note. A decline with no message can look cold.

Common mistakes

"I can't assist to the meeting." Spanish asistir a and Portuguese assistir a look like assist, but in English assist means help. The word you want is attend, with no "to". See more on Spanish false friends and Portuguese false friends.

✗ I can't assist to the meeting on Thursday.
✓ I can't attend the meeting on Thursday.

"Sorry, I won't go." Won't says you choose not to. It's correct, but it sounds rude for a meeting.

✗ Sorry, I won't go to the meeting.
✓ Sorry, I won't be able to make it.

"I have another meeting in the same hour." English says at the same time, or names the clash directly.

✗ I have another meeting in the same hour.
✓ I have another meeting at the same time. / I'm double-booked at 3.

If it's your whole day you need, see asking for a day off. If you need help instead of a meeting, see asking a colleague for help.

Questions

Do I need to give a reason when I decline a meeting?

A short one helps, but you don't need details. "I have a prior commitment" or "I'm with a client" is enough. For a formal invitation, the first one is the standard phrase.

How do I decline a meeting with my boss?

Be more careful: explain the clash and offer two other times. "I'm on the client call at 3. Could we do 4:30 or tomorrow at 10?" If the meeting can't move, ask what you should prepare in writing.

Is it rude to decline at the last minute?

It's less polite, so say sorry and give the reason: "I'm sorry for the short notice. Something urgent came up with [client], and I can't join at 2." Then send your input in writing.

Should I decline in the calendar or by message?

Both is best. Decline in the calendar so the organizer's view is right, and add a note or send a short message with your offer.
