Experimental limits on half-lives of the $(0\nu + 2\nu)\beta\beta$ decay of 130Te to excited states of 130Xe are obtained using low-background HPGe detectors. At the 90% CL, these limits are equal to $1.6\cdot 10^{21}$ y, $2.7\cdot 10^{21}$ y and $2.3\cdot 10^{21}$ y for transitions to the 2+1, 2+2 and 0+1 levels, respectively.
