Summary: Let \(G\) be a simple graph. The incidence energy (\(IE\) for short) of \(G\) is defined as the sum of the singular values of the incidence matrix. In this paper, a new upper bound for \(IE\) of graphs in terms of the maximum degree is given. Meanwhile, bounds for \(IE\) of the line graph of a semiregular graph and the paraline graph of a regular graph are obtained.
