■ Features of This App
▸ Displays the basis for calculations
It doesn't just throw numbers at you. You can see step-by-step how much the tax base is, what tax rates were applied, and what deductions were applied.
▸ Calculate Both to Choose Which Is More Advantageous
Just like the Standard Tax Credit and Special Deductions in Year-End Tax Settlement, or the Lump-sum and Individual Deductions in Inheritance Tax,
For cases where it is a "one of two" situation, it calculates both options and selects the one with the lower tax.
▸ Connects Calculators
Once you calculate your severance pay, that exact amount is transferred directly to the severance income tax.
It continues calculations from acquisition tax to registration fees, and from comprehensive income tax to local income tax.
▸ You Can Send Results
You can copy the calculation details exactly and send them to a tax accountant or family member.
▸ Go Directly to the Official Calculator
Links to Hometax and Wetax mock calculations are provided. Please compare them yourself.
▸ No Internet Access Required
All calculations are completed within your phone. It works even on the subway.
▸ Collects Nothing
There is no membership registration. The amounts you enter do not leave your phone.
There are no advertisements. ▸ Changes in tax laws are reflected immediately
Since the system retrieves tax rate tables separately, you do not need to wait for app updates.
