The tax deposit is one of the newest features in the Directorate General of Taxes’ (DGT) Coretax system, designed to simplify settling tax obligations for all taxpayers, although in practice it is highly relevant to the needs of government agencies. Despite being closely related to tax payments, depositing funds into a deposit account does not automatically mean a specific tax obligation is considered settled.

 

A tax deposit is essentially a temporary electronic wallet (e-wallet) that ensures smooth expenditure administration and secures a reserve for future tax payments. Although the deposited funds have legally entered the State Treasury and the taxpayer receives a State Revenue Transaction Number (Nomor Transaksi Penerimaan Negara/NTPN), the funds remain in deposit status (unallocated). The tax obligation is not considered settled until the balance is officially allocated to pay off a tax assessment or tax due.

 

Citing an explanation from the DGT on its official website, there are several key points that need to be understood regarding the use of tax deposits in the Coretax system, ranging from the reasons for its use by government agencies and the settlement mechanism to the causes of idle deposit balances.

 

So, why has this facility become the primary choice for government agencies, and why does the tax deposit balance accumulate without resulting in tax settlement?

 

Reasons Government Agencies Choose Deposits

 

The use of tax deposits within government agencies is heavily influenced by the need to fulfill budget disbursement administration. In the procurement of goods and services, government treasurers are required to complete tax administration documents before payments to providers can be processed.

 

Through this Coretax feature, treasurers can obtain a billing code more quickly by creating a deposit billing. The funds are then paid into the deposit account, allowing preliminary administrative requirements to be met without having to wait for the entire tax calculation and reporting process to be completed.

 

This mechanism is much more streamlined in the initial stages than regular tax payments. Under the standard mechanism, the treasurer must first complete the calculation and record the draft withholding tax slip or draft tax return (SPT) so the system can issue a payment billing code. Only after the bill is paid can the tax return be officially filed. This upfront convenience is what drives many agencies to utilize the tax deposit feature.

 

Differences Between Deposits and Payments

 

The ease of creating a deposit billing code often leads to the misconception that depositing funds means the tax obligation has been settled. In reality, making a deposit and settling a tax are two distinct processes with different legal and administrative consequences.

 

Depositing funds merely increases the available balance within the taxpayer's tax system. Tax payment or settlement only occurs when the deposit balance is allocated to pay off the tax due, whether arising from tax return filing or the issuance of a tax assessment.

 

This mechanism is similar to topping up an e-wallet balance. Topping up means funds are available in the account, but a purchase transaction has not occurred until the balance is used to pay for goods or services. Similarly, with a tax deposit, the funds are only legally recognized as a tax settlement once they are allocated to fulfill a specific tax obligation.

 

Steps for Settling Taxes via Deposit

 

For the deposit balance to be converted into a valid tax settlement, the treasurer must still complete all stages of tax administration. This process begins with issuing tax withholding slips (such as Article 21, Article 22, or Article 23 Income Tax) and administering VAT collection, depending on the transaction type.

 

Next, the withholding or collection slips that have been created will automatically be prepopulated into the periodic tax return (SPT Masa) within the Coretax system. Through this mechanism, the system instantly calculates the tax due during the slip recording phase, rather than only at the time of filing. Once the tax return is ready to be filed and shows an underpayment status, the treasurer can choose the payment option using the deposit balance. If the balance is sufficient, the system will allocate it to settle the tax obligation.

 

However, if the deposit balance is insufficient to cover the entire tax due, the treasurer must settle the shortfall through a payment using a regular payment billing code.

 

Risks of Idle Deposit Balances

 

Large idle deposit balances generally result from a halt in the administrative process after funds are deposited.

 

In practice, government agencies often create deposit billings and deposit funds to rush the completion of budget disbursement documents, but the subsequent steps are not immediately followed up. Treasurers might forget or delay creating withholding slips, filing the periodic tax return, and executing the deposit balance allocation to settle the bill.

 

Tax deposits are designed to accelerate tax administration, not to park expenditure budgets. Regular balance monitoring and discipline in completing periodic tax returns are key to ensuring that deposit balances do not sit idle and that tax obligations are legally fulfilled.
