State Revenue Soars, Purbaya: SPT Data Manipulation Becomes Increasingly Difficult Thanks to Coretax
Finance Minister Purbaya Yudhi Sadewa stated that the implementation of the DJP’s Coretax system in the taxation process has had a positive impact on state revenue.
“Coretax shows that although there were weaknesses, we have fixed them and now it’s quite good, but the impact on revenue is clearly very positive,” said Purbaya during the APBN KiTa April 2026 edition press conference at the Ministry of Finance, Jakarta, on Tuesday, 5 May 2026.
He reported that as of 30 April 2026, the number of Annual Tax Returns (SPT) entering the DJP Coretax system reached 13,056,881 SPT.
The breakdown includes 10,743,907 for employee personal taxpayers, 1,438,498 for non-employee personal taxpayers, and 874,476 for corporate taxpayers.
Purbaya explained that one of the positive impacts of implementing the DJP Coretax system is evident in the growth of underpayment SPT values and the decline in overpayment SPT values.
DJP recorded that the underpayment SPT value for employee personal taxpayers grew by 83%, for non-employee personal taxpayers it grew significantly by 949%, and for corporate taxpayers it grew by 18%.
Meanwhile, the overpayment SPT value for employee personal taxpayers contracted by 46%, for non-employee personal taxpayers it fell by 96%. The overpayment SPT by corporate taxpayers still grew by 59%.
“There is an increase in the underpayment SPT value, so basically the Coretax system is good because you don’t have to enter the SPT yourself. The tax data is placed all at once and consolidated directly,” said the Finance Minister.
With that system, Purbaya believes that efforts to manipulate SPT data are becoming increasingly difficult, making the reporting process more effective than in previous years.
To date, the state revenue data published by the Ministry of Finance covers data up to 31 March 2026. For Q1 2026 data, state revenue was collected at Rp574.9 trillion or grew 10.5% year-on-year (yoy).
Specifically for tax revenue, the realisation was recorded at Rp394.8 trillion or grew 20.7% (yoy).
Tax growth was mainly supported by value-added tax (PPN) and luxury goods sales tax (PPnBM) as well as income tax (PPh), influenced by increased economic activity and the improving implementation of Coretax.
