Beta Testing & Iteration

DETAIL PRODUCT & REQUIREMENT

The Indonesian government is implementing new regulations for income tax calculation (PPh 21)

The government, through the Ministry of Finance (Kemenkeu), has introduced a new calculation formula for Income Tax Article 21 (PPh21) with the implementation of the Average Effective Rate (TER). This policy will take effect starting from January 2024.

Problems

People still confused about how to calculate and report the taxes.

How can we help users to calculate and make tax reports under the latest regulations?

Government regulations sometimes change, make it more difficult calculate.

Requirements

This project was client-based, which means that all the designs built with the team must be approved by the client before we hand them over to the developers. Here are the details of the features:

  1. Permanent and Non-Permanent Employee Database
  2. Creation of Tax Deduction Evidence 1721 A1
  3. Creation of Tax Deduction Evidence for Non-Permanent Employees
  4. Creation & Reporting of Annual Income Tax (PPh) Article 21 Notification Letters
  5. Payroll Calculation

RESEARCH & PLANNING

Understanding The New Tax Calculation Formula

Before we start designing, the critical thing we need to understand is how it works. So, I decided to take a tour and learn about the new procedure for tax calculation. Here’s the new formula:

Old Flow Tax Reporting

Build the New Flow

The government claims that the new formula of calculation is simpler than the old one, but many people still don’t understand how to do it. Below is the step-by-step flow on how to perform calculations and generate reports with TaxKita.

UI DESIGN & PROTOTYPE

Hierarchy for a Large Amount of Inputs

Our concern is how to present a large amount of input and make it easy to understand for the user so they can easily calculate taxes seamlessly. For the first phase, we will focus on development for desktop devices. Development for the mobile version will be carried out in the next phase.

USABILITY TEST

Test the Design with 5 People

We conducted testing using Maze involving five people from the finance and operational divisions in our office. We asked them to try the TaxKita design. The results showed a 100% success rate for every task given to them.

Based on the test results above, it shows a 100% success rate for every task given to the user. Some users may need more time to complete tasks, but ultimately, they can still accomplish all of their tasks, which indicates the success of the design. Our clients have also reviewed and approved this design work, and we’re ready to enter the development phase.
