# All-in-One Payroll Tax Software for Easy Tax Filing
> Gadjian's payroll tax software is a feature that automatically calculates employee income tax withholding (PPh 21) and non-resident tax (PPh 26) based on each employee's salary data and tax status. It supports multiple calculation methods (gross, gross-up, net) for permanent employees, professional consultants, and foreign workers.
## What is Gadjian's payroll tax software?
Gadjian's payroll tax software is a feature within the Gadjian payroll application that calculates income tax withholding on employee salaries (PPh 21) as well as tax for non-resident foreign workers (PPh 26). The system calculates tax every month and performs a year-end recalculation, supporting gross, gross-up, and net methods. It also supports multiple company tax IDs (NPWP) for multi-entity tax management, and provides automatic correction (pembetulan) when tax regulations change or payroll data needs adjustment. Withholding tax slips (bukti potong) and reporting CSV files can be downloaded directly from the system.
## Who is this payroll tax software for?
- HR/Payroll teams at companies with diverse employee types: calculate tax for permanent employees, professional consultants, and foreign workers (expatriates) using the appropriate method.
- Companies with multiple entities/tax IDs (NPWP): manage tax calculation and recapitulation separately for each NPWP without mix-ups.
## Key Features

## How does it work?
1. Register employee data, income type, and company tax ID (NPWP) into Gadjian.
2. Select the applicable tax calculation method (gross, gross-up, or net) for each employee category.
3. Gadjian automatically calculates PPh 21 or PPh 26 for every payroll period.
4. The system performs a year-end recalculation or a correction when data or regulations change.
5. Download withholding tax slips and reporting CSV files directly from the app.
## What is the difference between PPh 21 and PPh 26?
The main difference lies in the taxpayer's residency status: PPh 21 applies to the income of resident individual taxpayers, while PPh 26 applies to income of non-resident taxpayers (for example, foreign workers staying less than 183 days in Indonesia) at a final rate of 20% of gross income [PERLU VERIFIKASI: confirm the 183-day threshold and final rate against the current Income Tax Law and any applicable tax treaty (P3B)]. Gadjian can calculate both automatically within a single system.
