The greatest benefit of Tashidaka system was that a financial load of the bakufu would be reduced because an amount of yield was returned to the past amount after retiring from a post under this system (however, taking it into consideration that ongoku-bugyo [the collective name of the magistrates placed at important areas directly controlled by the government in the Edo period] had more opportunities of spending expenses than people at other posts, yakuryo [executive allowance] was supplied separately whether or not tashidaka [wage] was paid).
足高の制によって、役職を退任すれば石高は旧来の額に戻るため、幕府の財政的な負担が軽減できるというのが最大の利点であった（ただし、遠国奉行は出費の機会が他の役職よりも多いことを考慮されて足高の有無を問わずに役料が別個に支給された）。
