The first mention of Ergoldsbach in writing dates back to 822. The land belonged to the Landshut Rentamt [bar; de; es] and the District Court of Teisbach in the electorate of Bavaria. At this time, Ergoldsbach had its own market court with a magistrate. Resulting from its location along the Landshut–Regensburg road, it developed through trade with the farming population. In the year 1403 it became a Municipality with Market town rights. Later on, some fires changed the town forever. In 1860 the Erlus brickworks were established, along with the opening of a railway line from Landshut to Geiselhöring, which resulted in an economic boom for the town. After a fire, the Erlus factory relocated its head office to Neufahrn nearby. All that remained in Ergoldsbach was the chimney. In 1913 a hospital was built in Ergoldsbach, which operated until 1977. After this it was used by the Red Cross, until conversion into a nursing home for seniors in 2004.

The Market town/municipality Ergoldsbach was founded between 1972-1978 by incorporating Prinkofen, Langenhettenbach, Paindlkofen, Kläham and Martinshaun.

In April 1945, policeman Max Maurer of the SS was delivered with 13 Jewish KZ prisoners, allegedly with the order to shoot them. Maurer took the prisoners to the property of Anna Gnadl, where a day later they were recovered by the American advancement. According to John Weiner, one of the 13, Maurer saved the prisoners' lives. This was recognised in 1997, when Yad Vashem of Israel presented the Righteous among the Nations award.

Ergoldsbach is on the Munich–Regensburg railway line and is served by Agilis and Deutsche Bahn. The Bundesstraße 15, an important federal highway, also runs through the town. In the near future a new road with four lanes is planned to reduce the traffic load on the marketplace in the town's center. The town belongs to the water authority of Rottenburg.

In 2007, the area owned by the Stiegler and Ziegler families was developed into a new centre.  With the demolition of Fassadenbaus, space was created for a supermarket and car park. In Jellenkofen there is a business park with a total area of 39.000 m². Furthermore, residential building areas are available on the Kapellenberg.
