年としをとる
Most common spelling; uses the kanji 年 for 'year' and kana for the rest.
歳としをとる
Uses 歳, which specifically means 'age' or 'years of age', giving a slightly more formal or literary feel.
年としを取とる
Uses the kanji 取る for the verb; less common than the kana spelling とる.
歳としを取とる
Combination of 歳 and 取る; rarely used.

老ふける
老ける implies aging in a negative or visible way (looking old, declining), while 年をとる is a neutral statement of getting older.
年としを重かさねる
年を重ねる is a more elegant, literary way to say 'to accumulate years', often with a positive nuance of gaining experience.

Compound of 年 (toshi, 'year, age') + を (o, object marker) + とる (toru, 'to take'). Literally 'to take years', i.e., to accumulate age.
