USC on rental income

Looking for clarification on what portion of rental income has one to pay usc on.For my 2014 returns I had slightly less than €2000 rental income after expenses, house insurance and mortgage protection policy were deducted from full rental income. I was charged usc on the €2000 figure. I had capital allowances from a countryside refurbisment scheme year 6 approx €16,000.Are capital allowances excluded from usc calculation?

Rental Profit before capital allowances.

Gross rental profit before deducting capital allowances is liable for USC as Joe_90 indicates. In regard to your question, use of your capital allowances reduces the income tax element.

Many thanks Joe 90 and Agent 47
