Where in the ITR12 can I claim toll fees paid on business trip if I don't use actual costs.

I have incurred toll fees while on travelling on business trips to clients. My employer does not reimburse this fees I incurred citing that I should cover them from the reimbusive travelling claim that I get. I don't use the actual cost incurred but rather the estimates as per tables. My question is, where in the ITR12 can I book this fees against my income.

How much are you reimbursed for travel and what source code is used on your IRP5 for the reimbursement income you receive?

My reimbursement is R4.80 per KM
The code is 3702

In order to claim travel expenses, you need to choose either the deemed cost method or the actual cost method. You can't use a hybrid of the two.You would claim the costs within the travel allowance section in your tax return.
