Understanding Input Tax and Output Tax under the Goods and Services Tax Act 1993: Key Provisions and Their Purpose
The Goods and Services Tax Act 1993 (GST Act) establishes a comprehensive framework for the administration of GST in Singapore. Central to this framework are the concepts of input tax and output tax, which govern how taxable persons account for GST on their business transactions. This article analyses the key provisions under Sections 19 and 20 of the GST Act, elucidating their purpose and practical implications for taxable persons.
Accounting Periods and Tax Credit Entitlement
"A taxable person must, in respect of supplies made by the taxable person, account for and pay tax by reference to such accounting periods as the Minister may by regulations prescribe... Subject to this section, a taxable person is entitled at the end of each such period to credit for so much of the taxable person’s input tax as is allowable under section 20, and then to deduct that amount from any output tax that is due from the taxable person." — Section 19(1), (2)

Section 19(1) and (2) impose a statutory obligation on taxable persons to account for GST within prescribed accounting periods. This ensures timely and systematic reporting and payment of GST, facilitating efficient tax administration. The entitlement to claim input tax credit at the end of each accounting period allows taxable persons to offset GST paid on business inputs against GST collected on outputs, thereby preventing cascading taxation.
Definitions of Input Tax and Output Tax
"‘input tax’, in relation to a taxable person, means the following: (i) tax on the supply to the taxable person of any goods or services; (ii) tax on the reverse charge supply treated as made by the taxable person (as a recipient) to himself, herself or itself under section 14(2); (iii) tax paid or payable by the taxable person on the importation of any goods, being...goods or services used or to be used for the purpose of any business carried on or to be carried on by the taxable person;" — Section 19(3)(a)
Verify Section 19 in source document →
"‘output tax’ means tax on supplies which a taxable person makes." — Section 19(3)(b)
Verify Section 19 in source document →
Section 19(3) provides precise definitions of input tax and output tax, which are fundamental to GST accounting. Input tax encompasses GST paid on goods and services acquired for business use, including reverse charge supplies and importation tax. Output tax refers to GST charged on supplies made by the taxable person. These definitions ensure clarity in identifying which taxes are creditable and which are payable, thereby supporting accurate tax computation.
Apportionment of Input Tax for Mixed Use Supplies
"Where...goods or services supplied to a taxable person...are used or to be used partly for the purposes of a business...tax on supplies and importations must be apportioned so that only so much as is referable to the taxable person’s business purposes is counted as the taxable person’s input tax." — Section 19(4)
Verify Section 19 in source document →
This provision addresses situations where goods or services are used partly for business and partly for non-business purposes. The requirement to apportion input tax ensures that only the portion attributable to business use is claimed as input tax credit. This prevents abuse of input tax claims and aligns tax credits with actual business consumption, preserving the integrity of the GST system.
Payment of Excess Input Tax Credit and Withholding Powers
"if either no output tax is due at the end of the period, or the amount of the credit exceeds that of the tax, then, the amount of the credit or...the amount of the excess must be paid to the taxable person by the Comptroller." — Section 19(5)
Verify Section 19 in source document →
"Where at the end of any period an amount is due...to a taxable person who has failed to submit returns...the Comptroller may withhold payment of that amount until that person has submitted the returns...and deduct from the amount due any tax or penalty which the taxable person is liable to pay and which remains unpaid." — Section 19(7)
Verify Section 19 in source document →
Section 19(5) ensures that taxable persons are reimbursed for any excess input tax credits when their output tax liability is lower or nil, supporting cash flow for businesses. However, Section 19(7) empowers the Comptroller to withhold such payments if the taxable person has not complied with statutory obligations such as submitting returns or paying outstanding tax or penalties. This safeguard protects public revenue by ensuring compliance before refunds are made.
Claims and Regulatory Conditions on Input Tax Credit
"No deduction may be made under subsection (2) nor any payment made under subsection (5), except on a claim made in the manner and within the time prescribed by regulations." — Section 19(8)
Verify Section 19 in source document →
"The Minister may by regulations provide...for tax on the supply of goods or services to a taxable person...to be treated as the taxable person’s input tax only if and to the extent that the charge to tax is evidenced and quantified by reference to such documents as may be specified..." — Section 19(13)(a)
Verify Section 19 in source document →
These provisions require taxable persons to submit claims for input tax credit in accordance with prescribed procedures and within specified timeframes. The Minister’s power to impose documentary requirements ensures that input tax claims are substantiated by appropriate evidence, reducing the risk of fraudulent claims and enhancing the accuracy of tax administration.
Allowable Input Tax and Attribution to Business Supplies
"The amount of input tax for which a taxable person is entitled to credit...is so much of the input tax for the period...as is allowable by or under regulations as being attributable to supplies within subsection (2)." — Section 20(1)
Verify Section 20 in source document →
"The supplies within this subsection are the following supplies made or to be made by the taxable person in the course or furtherance of the taxable person’s business: (a) taxable supplies; (aa) supplies permitted to be made under section 27...; (b) supplies outside Singapore which would be taxable supplies if made in Singapore; (c) such other supplies outside Singapore as the Minister may by regulations specify...; (d) supplies which section 37...provide are to be disregarded for the purposes of this Act and which would otherwise be taxable supplies." — Section 20(2)
Verify Section 20 in source document →
Section 20 delineates the scope of supplies to which input tax can be attributed. Only input tax related to supplies made in the course or furtherance of business activities is allowable. This ensures that input tax credits are confined to genuine business transactions, preventing misuse of credits on non-business or exempt supplies. The inclusion of certain supplies outside Singapore and disregarded supplies underlines the comprehensive approach to defining taxable supplies for input tax purposes.
Exclusion of Input Tax in Arrangements Causing Loss of Public Revenue
"Despite subsection (1), a taxable person is not entitled to credit for any input tax on any supply made to the taxable person which the taxable person knew or should have known was a part of any arrangement to cause loss of public revenue..." — Section 20(2A)
Verify Section 20 in source document →
This anti-avoidance provision denies input tax credit where the taxable person is involved in arrangements designed to evade tax or cause loss of public revenue. It serves as a deterrent against tax fraud and protects the integrity of the GST system by ensuring that input tax credits are not claimed in abusive schemes.
Regulatory Powers for Fair Attribution and Treatment of Supplies
"Regulations may provide for treating some or all supplies of goods or services by any person as taxable supplies..." — Section 20(3)
Verify Section 20 in source document →
"The Minister may make regulations for securing a fair and reasonable attribution of input tax to supplies within subsection (2)..." — Section 20(4)
Verify Section 20 in source document →
These provisions empower the Minister to make regulations that ensure fair and reasonable attribution of input tax to various supplies and to treat certain supplies as taxable for input tax purposes. This flexibility allows the GST regime to adapt to complex commercial arrangements and evolving business practices, maintaining fairness and consistency in tax treatment.
Definitions Relevant to Input Tax and Output Tax
Precise definitions are critical for the correct application of GST provisions. Section 19(3)(a) and (b) define input tax and output tax respectively, as discussed above. Additionally, Section 19(15) introduces the concepts of the "initial specified period" and "subsequent specified period," which relate to the timeframes within which input tax adjustments may be made.
"‘initial specified period’ means a period of 12 months after the due date for payment of the consideration or the part thereof (as the case may be) by the taxable person to the taxable person’s supplier;" — Section 19(15)
Verify Section 19 in source document →
"‘subsequent specified period’ means — (a) where the prescribed accounting period during which the relevant input tax was first credited under subsection (2) ends before 1 January 2007, a period — (i) commencing on the day immediately following the end of the initial specified period; and (ii) ending on a day 6 years after the end of that prescribed accounting period; or (b) where the prescribed accounting period during which the relevant input tax was first credited under subsection (2) ends on or after 1 January 2007, a period — (i) commencing on the day immediately following the end of the initial specified period; and (ii) ending on a day 5 years after the end of that prescribed accounting period." — Section 19(15)
These periods govern the timeframe for making adjustments to input tax claims, reflecting the need for certainty and finality in tax accounting while allowing for corrections in cases such as credit notes or changes in use.
Penalties and Compliance Enforcement
Section 19(7) empowers the Comptroller to enforce compliance by withholding payments of input tax credits or excess amounts where taxable persons have failed to submit returns, comply with information requests, or pay outstanding tax or penalties.
"Where at the end of any period an amount is due under subsection (5) to a taxable person who has failed to submit returns, to comply with any reasonable request by the Comptroller for information or to pay tax or penalty for any period as required by this Act, the Comptroller may — (a) withhold payment of that amount until that person has submitted the returns, complied with the request or paid the tax or penalty, as the case may be; and (b) deduct from the amount due any tax or penalty which the taxable person is liable to pay and which remains unpaid." — Section 19(7)

This provision is essential for safeguarding public revenue and ensuring that taxable persons meet their statutory obligations before receiving refunds or credits. It acts as a compliance mechanism to deter non-compliance and facilitate effective tax collection.
Cross-References to Other Provisions and Acts
The GST Act cross-references several other sections and regulations to provide a cohesive tax framework:
- Section 14(2) on reverse charge supplies, which are treated as supplies made by the taxable person to themselves for input tax purposes [Section 19(3)(a)(ii)].
- Section 27 and related regulations permitting certain supplies to be made without payment of tax but still eligible for input tax credit [Section 20(2)(aa)].
- Section 37 and 37A concerning supplies disregarded for GST purposes, which are nonetheless considered for input tax attribution [Section 20(2)(d)].
- Section 37B and the Fourth Schedule relating to supplies of investment precious metals by approved persons [Section 20(2)(ab)].
- Section 27A regulations relating to tax on importation, clarifying when import tax is accounted for [Section 19(3A)].

Conclusion
The provisions under Sections 19 and 20 of the Goods and Services Tax Act 1993 establish a detailed and balanced regime for the accounting and claiming of input tax credits and output tax liabilities by taxable persons. They serve multiple purposes: ensuring timely tax accounting, preventing tax avoidance, safeguarding public revenue, and providing flexibility to accommodate complex commercial realities. Understanding these provisions is essential for taxable persons to comply effectively with GST obligations and to optimise their tax positions within the legal framework.
