Saying no to your boss is rarely a flat no. It is asking your boss to make the priority trade-off that already belongs to them. You show your current load, ask which task moves, and then confirm the agreement in writing. That protects the commitments you already made without looking uncommitted.
If the overload has been building for months and is not just one bad week, Is it burnout or the job? can help you tell the difference between a hard stretch and something deeper.
What you are actually saying no to: time, scope, a deadline, or the request itself
A no is aimed at one of four things: the time it would take, the scope of the request, the deadline attached to it, or the request itself. Name the thing before you answer. If the problem is the deadline, the conversation is about dates. If the problem is scope, the conversation is about what fits inside the task. If the problem is the request itself, the conversation is about your role.
Turn the no into a priority question
A no to a boss works better as a question that forces the priority choice onto the person who owns it. Show what is already on your plate and ask what moves.
A script that fits many cases:
"I can do X by Friday if Y moves to next week. Which do you want first?"
This makes the effect on your other tasks visible and leaves the decision about what matters now to your boss.
When a flat no is right
A flat no fits two situations more than it fits daily overload: the request is outside your role, or it would make you miss a commitment you already made.
In either case, do not just say no and stop. Say what you can do instead, and name the commitment the request would break. For example: "I can't take that on this week without missing the client review I already confirmed for Thursday. I can start it Monday." That keeps the no specific and useful.
If the request is unethical or illegal, that is a different situation and needs a different response.
Put the agreement in writing
After the conversation, send a short email that repeats the decision. Write what you agreed to do, what moved, and the new order of priorities. A two-line email is enough.
Sticking to the written version is easier when the same task comes back or when someone remembers the conversation differently. The email does not need to be formal. It only needs to be clear.
If every no is punished
A single hard conversation is normal. When every no is treated as disloyalty, the issue is the response you get, and that tells you something about the role. When to leave because of your boss covers that pattern.
A hypothetical
Invented example, with made-up names. Alex is already running the monthly close, a hiring report, and a client deck. Her boss adds a pricing analysis and calls it urgent. Alex answers: "I can do the pricing analysis by Friday if the client deck moves to Monday. Which do you want first?" The boss picks the pricing analysis. Alex sends a two-line email: the pricing analysis is due Friday, the client deck is now due Monday.
What saying yes to everything hides
Saying yes to everything also shapes your position: the work you absorb can hide the work you want to be known for.

FAQ
How do I say no to my boss without hurting my career?

What should I say when my boss gives me too much work?
Name the trade-off in one sentence. For example: "I can do X by Friday if Y moves to next week. Which do you want first?" This makes the effect on your other tasks visible and leaves the decision about what matters now to your boss.
When should I give a flat no to my boss?
A flat no fits when the request is outside your role or would make you miss a commitment you already made. Say what you can do instead, and explain which commitment the request would break. If the request is unethical or illegal, that is a different situation and needs a different response.
How do I make a no stick after the conversation?
Send a short email that repeats the decision. Write what you agreed to do, what moved, and the new order of priorities. That gives you a record if the same task comes back or if someone remembers the conversation differently.
