Like a good IRS officer, Henry clearly demonstrated the mission of the tax office he works at and ? he is absolutely right! You can see that exactly in the attached picture. You can have your needs satisfied without leaving the tax office. Obviously, you will be satisfied when you fill in your PIT return and send it online. Overall, the online technology is present everywhere. For instance, accountants may have an independent check of their CIT calculation without involving any third party. This mitigates the risk of errors in income tax calculations and it somewhat satisfying that you have done it yourself and for practically no money.
