He came from the Baltic German noble family of ; his father Christoph Adam von Reutern (1782–1833) was a lieutenant-general in the Imperial Russian Army and his mother Charlotte Elisabeth von Helffreich was a noblewoman. He was the nephew of the famous painter Gerhardt Wilhelm von Reutern. The Reuterns were of Holsteinish descent, originating in Lübeck. The family was originally called Reuter, they got their name when Johann Reuter (1635–1698), a merchant, was raised to in the Swedish nobility in 1691.

In 1862, he was appointed finance minister under the liberal reformist tsar, Alexander II, and introduced a system of public accounting. Reutern's period in office was also marked by the promotion of private credit institutions and attempts to stabilise the ruble. He succeeded in reforming taxation and customs laws, by abolishing the spirits lease and the introduction of an excise tax on brandy. Government revenues rose significantly, the chronic budget deficit was removed in 1867, and budgetary surpluses were achieved from 1873. On trade policy, Reutern pragmatically supported reducing some tariffs and duties on manufacturing goods in 1863 and 1868.
The Russo-Turkish War reversed some of the measures that had led to Reutern's successes, and he resigned in 1878.
