According to the current personal income tax regulations, if the income from the remuneration for writing is more than 4,000 yuan (including 4,000 yuan), the necessary expenses shall be deducted according to 20% of the income, and then the personal income tax shall be calculated according to the reduction of 20% and 30%.

Calculate Mr. Zhang's personal income tax: 4000 * (1-20%) * 20% * (1-30%) = 448 yuan.

So the actual after-tax income is 4000-448=3552 yuan.
