Step 1: ICC2
My teenage son was recently diagnosed with autism (ASD).
My GP was aware that we were going through that process and I shared the report with her.
I brought firm ICC2 into her and she signed off:
-that incapacity has been present since birth
-permanent
-cannot be improved by treatment
- unable to maintain themselves on reaching 18
- listed the incapacity ASD
Step 2: ICC1
I wasnt aware initially but there is another form ICC1.. I completed that one:
- stated that no one else is maintaining child
- provided bank details for refund
Step 3: claim tax credit
Claim additional tax credit by uploading both forms to revenue.ie via manage my tax for current year
- this took few days but credit was applied
Step 4: refund for previous years
If you have already completed tax returns abd have statement of liability then refund should issue automatically
In my case, 2020 hadnt been submittee so I completed that and the credit offset taxes due, statement of liability provided and refund was issued
Step 5: current year
Ive just moved job, so was emergency taxed first month as both employments were still on revenue. Im not 100% sure how this is being dealt with but I expect credit to be applied next pay cycle.
