The best thing about fermented beverages is that they can last for years. And soy sauce is one of the shelf-stable beverages you can enjoy anywhere. But that does not mean soy sauce can’t go bad. 

Soy sauce can retain quality for years but will eventually turn bland. An unopened sauce bottle will last 2-3 years past the printed date. Once opened, the peak flavor of the sauce will last a year at room temperature. Store the sauce in the fridge, and you will be good for another 6 months.

Once the date is passed, the soy sauce can still be used. However, the old soy sauce will not be as flavorful as the new one. But that does not mean the sauce has gone bad. If your soy sauce begins to show signs of spoilage, then the sauce has gone bad. Look for mold or a funny smell to know that the sauce has gone bad.
