Does a digital piano ever need tuning?
No, a digital piano never needs tuning. With an acoustic piano, you usually have to tune it once a year, if not more often. If you don’t tune an acoustic piano regularly, the sound will deteriorate to the point it becomes unusable as a legitimate musical instrument. On the other hand, the sounds for a digital piano are recorded and stored within the hardware, so it does not go out of tune. In fact, digital pianos are relatively low maintenance instruments. Keep it dusted, out of direct sunlight and away from spilled liquids, and your digital piano will last many, many years of everyday use.
