How to say "impose" in Japanese

• 課するかするCommon
  suru verb (irregular), transitive verbCovers imposing or levying a tax, fine, or similar charge, and assigning a task or duty, typically in official or administrative contexts. A natural choice when the subject is a government or authority.
  この学校がっこうは生徒せいと達たちに高度こうどな道徳どうとく水準すいじゅんを課かする。↗

  This school sets high moral standards for pupils.
• 課すかすCommon
  godan verb, transitive verbA variant of the same verb as 課する, with the same senses: imposing taxes or fines and assigning duties. The two are largely interchangeable, with 課す the more colloquial-seeming form.
  新あたらしい税金ぜいきんがワインにかせられた。↗

  A new tax was imposed on wine.
• 科するかするCommon
  suru verb (irregular), transitive verbUsed for inflicting or imposing a fine or similar penalty, especially in legal contexts. It is narrower than 課する, since it does not cover assigning ordinary tasks or duties; for those, 課する is the word to reach for.
  裁判官さいばんかんは彼かれに重おもい罰金ばっきんを科かせるのだろうか。↗

  Will the judge fine him heavily?
• 強いるしいるJLPT N1approx.Common
  ichidan verb, transitive verbMeans to force, compel or coerce someone to do something. When 'impose' implies pressing something on a person against their will in this forceful way, this is the natural verb; it does not suit formal levying of taxes or fines.
  彼かれらは我々われわれに服従ふくじゅうを強しいた。↗

  They enforced obedience upon us.
• 押し付けるおしつけるCommon
  ichidan verb, transitive verbSuits imposing one's will on someone, or foisting a task or responsibility on them, often with a nuance of unfairness or annoyance. It is colloquial and physical in flavor, not the verb for levying taxes or fines.
  先月せんげつの日直にっちょく当番とうばん全部ぜんぶ私に押し付おしつけた形かたちでエスケープした野郎やろうだ。↗

  He's the pest that, on last month's class-help day, escaped leaving me with all the work.

Use 「課する」/「課す」 or 「科する」 for formally levying taxes, fines and duties, 「強いる」 for forcing something on someone, and 「押し付ける」 for foisting tasks, responsibilities or one's will on unwilling people.
