A novel formulation of tapered beam propagation algorithm is given. The new algorithm is tested on standard taper structures in order to check the accuracy, reciprocity and the convergence rate. It is shown that the new algorithm preserves the advantages of the previous formulation while being easier to implement and requiring less computation per one propagation step. The results obtained by the new algorithm agree with ones given by the standard rectangular beam propagation method and also fulfil the reciprocity condition to four decimal places of the transmitted power.
