Which is the better way to declare personal income tax for children's education?

In my opinion, if the taxpayer has a work unit, the declaration method of personal income tax children's education should be declared through the withholding agent; If you don't have a work unit, you should choose the year of comprehensive income to declare yourself, that is, from March/kloc-0 to June 30 of the following year, you should go to the tax authorities to handle the summary tax declaration.
