The English verb "impose" covers several distinct meanings: forcing rules or burdens, taking advantage of someone's hospitality, and asserting authority. Japanese uses different words and structures for each.
To officially require something, such as a law, tax, fine, or restriction.
impose a tax · impose a fine · impose restrictions · impose one's will
The most direct equivalent for imposing taxes, fines, duties, or penalties. Often used in official contexts.
The government imposed a new tax.

Similar to 課す, but more specifically used for penalties, punishments, or sentences. Often interchangeable with 課す in legal contexts.

Means to force something onto someone, often with a negative connotation of being unfair or unwanted. Used for rules, opinions, or work.

To cause inconvenience by expecting too much from someone's generosity, often by staying too long or asking for favors.

Literally 'to cause trouble/annoyance'. The most natural way to express the idea of imposing on someone in social situations.

A polite phrase meaning to accept someone's kind offer, often used when you are 'imposing' by taking them up on their hospitality. It softens the imposition.
To make someone accept your authority, presence, or ideas, often in a domineering way.
impose one's authority · impose one's beliefs · impose oneself on others
Again, 'to force onto'. Works for imposing opinions, beliefs, or one's presence.

Both mean 'to impose' and are read かす. 課す is broader (taxes, duties, tasks), while 科す is mainly for legal penalties. In modern usage, 課す is more common and often replaces 科す.
Both mean 'impose a fine', but 課す is more common.
The government imposed a new tax.
