No. Digital pianos do not need to be tuned. They do not go out of tune as the seasons change. A bonus option is you can adjust the piano tuning when playing with others. Ranges are often from A-415Hz to 460Hz. You can also change tuning temperaments with a few clicks from Equal Tempered Tuning to different kinds of Mean-Tone tuning, and Just Tuning. If desired, a player can set a digital piano to a tuning for a specific key, so when playing in that key it will sound better than a properly tuned acoustic piano.
