How much can I prune off a tree at one time?
Short answer
A common rough guideline is to avoid removing more than about a quarter of the living crown in one season. Healthy mature trees may handle this. Young, old or stressed trees may need less. Ask a certified arborist to look at your tree first.

The longer answer
Leaves make the food a tree lives on. If you cut off too many in one year, the tree has less energy to heal wounds and fight pests. That is why a light, careful cut usually beats a heavy one.
The quarter rule is a general guide, not a law of nature. Some trees tolerate more. Others, like older trees or ones with root damage, tolerate less. If a tree needs a lot of work, a good arborist often spreads it over two or three seasons.
Be wary of anyone who offers to cut the tree back hard to a few stubs. That is topping, and it often causes weak new growth and decay.
Ask the company to explain what they plan to cut and why. A good answer names the goal, such as removing deadwood, lifting low branches or thinning for light.
