Filing a corporate VAT Periodic Tax Return in Coretax is a monthly obligation for Taxable Entrepreneurs (Pengusaha Kena Pajak / PKP) registered with the Directorate General of Taxes (DJP). The Coretax DJP system allows companies to report taxes online, starting from inputting output tax invoices, input tax invoices, to submitting the SPT 1111 electronically.
If done correctly, the reporting process can be completed in just a few simple steps. However, many companies still experience challenges with invoice data synchronization, generating draft SPT, and the electronic signature process.
This article explains how to file a corporate VAT Periodic Tax Return in Coretax in detail, including document preparation, reporting steps, and common mistakes that often occur.
Preparation Before Filing the VAT Periodic Tax Return
Before starting to create the report in Coretax, companies must ensure that all tax data is ready and aligned with the taxpayer profile.
Some documents and data that need to be prepared include:
- Corporate NPWP
- Active EFIN
- DJP Electronic Certificate
- PKP profile data in the Coretax system
- Output Tax Invoices (FPK)
- Input Tax Invoices (FPM)
- Tax invoice XML or Excel files
- Supporting documents for SPT Form 1111
These documents are important because the Coretax system will retrieve data from tax invoices to automatically calculate VAT.

Steps to File the VAT Periodic Tax Return in Coretax
Below are the main steps for reporting VAT Periodic Tax Return (SPT Masa PPN) through the Coretax application.
1. Log in to the Coretax DJP System
Access the official Coretax portal using your company account with the corporate NPWP and the credentials of the director or the designated tax PIC.
Make sure you log in using the company account, not a personal account.
2. Input Output and Input Tax Invoices
Go to the e-Faktur menu and input the following data:
- Output Tax Invoices (sales)
- Input Tax Invoices (purchases)
Data can be entered manually or imported via Excel/XML files to speed up the process.
These invoices will become the basis for tax calculations in the VAT Periodic Tax Return.
3. Access the VAT Periodic Tax Return Menu
Once all invoices are recorded, open the menu:
SPT → VAT Periodic Tax Return (SPT Masa PPN)
The system will usually generate a draft SPT automatically at the beginning of the following month.
At this stage, you need to review several important attachments, such as:
- Attachment A2 (Domestic Output Tax)
- Attachment B2 (Domestic Input Tax)
If there are consolidated invoices, upload the XML file in the attachment section.
4. Review the VAT Calculation
Coretax will automatically calculate the tax results based on invoice data.
The calculation status usually appears as:
- VAT Underpayment
- VAT Overpayment
- VAT Nil
Ensure that all data is correct before proceeding with the reporting process.
5. Electronic Signature and Submit the Tax Return
If all data is correct, follow these steps:
- Tick the statement confirming the accuracy of the data
- Select the signatory position
- Use the DJP Electronic Certificate for the digital signature
- Click Pay & File the SPT Tax Return
The system will then process the report submission.
6. Payment if There Is an Underpayment
If the calculation result shows VAT underpayment, the system will generate a tax billing code.
Payments can be made through:
- perception banks
- internet banking
- official tax payment channels
After the payment is successful, the SPT status will change to Reported.

Late submission may result in administrative penalties in accordance with tax regulations.
