Other deductible expenses not recorded in the accounts

All business-related tax-deductible expenses that are not included in the profit and loss account for the accounting period are reported in this section. The expenses in this category include

  • expenses for the use of a private dwelling for business purposes, or a workspace deduction
  • temporary or combined deductions for research and development.

How to file in MyTax

Open the specification to report a workspace deduction or the expenses that you are deducting for the use of a private dwelling for business purposes. Select the actual expenses or the workspace deduction. Answer the additional questions. Please note that MyTax calculates the amount of the workplace deduction automatically based on the answers you give.

If you claim a temporary additional deduction for research and development, open form 67A in MyTax. 

If you claim a combined deduction for research and development, open the form 67Y in MyTax. 

MyTax calculates the amount of the other deductible expenses.

How to file on a paper form

If you have not deducted the expenses in the profit and loss account, report them in section 2.3, subsection “Deductible expenses not entered in the accounts”. Report either a workspace deduction or a business-related portion of the actual costs of using your own residence for business purposes.

If the expenses have been entered in the accounts, report them in section 2.3, subsection “Other deductible expenses”.

In addition, itemise the expenses in section 8 “Itemisation of use of private residence for business purposes”.

Report the additional deduction for research and development: Form 67A or form 67Y.
