Claiming Input Tax Incurred to Make Exempt Supplies

Generally, input tax incurred in the making of exempt supplies is not claimable unless the De Minimis Rule is satisfied. The De Minimis Rule allows GST-registered businesses to claim input tax on exempt supplies.

De Minimis Rule

To satisfy the De Minimis Rule, the value of the exempt supplies has to be less than or equal to:

  1. Average of $40,000 per month; and
  2. 5% of the total value of all taxable and exempt supplies made in that period.

When De Minimis Rule is Satisfied

When the De Minimis Rule is satisfied, you may claim all input tax incurred, excluding disallowed input tax under regulations 26 and 27 of the GST (General) Regulations.

As the input tax claims are only provisionally allowed at the end of each prescribed accounting period, you are still required to perform a longer period adjustment by performing the same test in respect of the input tax claims you have made in the longer period.

When De Minimis Rule is Not Satisfied

When the De Minimis rule is not satisfied, you are not allowed to claim input tax directly attributable to the making of exempt supplies.

For input tax that cannot be identified as directly attributable to either taxable or exempt supplies (residual input tax), the amount that can be claimed is computed using the following formula:

To arrive at the total allowable residual input tax, you should multiply the residual input tax before apportionment by the proportion of the value of taxable supplies to the value of total supplies.

  • I made the following supplies in my prescribed accounting period of 1 Apr 2014 to 30 Jun 2014. Can I claim all the input tax incurred in this period for the making of exempt supplies?

    Standard-rated supplies$2,080,000
    Zero-rated supplies$300,000
    Exempt supplies$120,000
    Total supplies$2,500,000

    Applying the De Minimis Rule:

    1. Value of average exempt supplies per month = $120,000 ÷ 3 = $40,000.
    2. Percentage of exempt supplies over the total supplies = ($120,000 / $2,500,000) x 100% = 4.8%

    Since the value of average exempt supplies is not more than $40,000 per month and 5% of the total value of supplies, the De Minimis Rule is satisfied and all input tax incurred for the making of exempt supplies are provisionally claimable.
