discrete wavelet transform (ReverseBiorthogonalSplineWavelet[8,8] family), the accuracy of which is higher than 99% ("RSquared"0.999793).The scientific novelty of the proposed method of improving the accuracy of forecasting monthly budget revenues of the RF subjects lies in the fact that the necessity of preliminary decomposition of the time series and subsequent construction of forecasts for the obtained parts has been proved, resulting in high forecast accuracy.The obtained result differs significantly from the results of using traditional econometric methods (ARIMA/SARIMA), which are characterised by much lower accuracy (50-80%) and decreasing accuracy of forecasts with increasing forecast horizon.This article is new, as it forms a new approach to solving the problem of improving the accuracy of forecasts of budget revenues at all levels, which allows for more effective budget and investment policy.
