Food, medical supplies and other forms of disaster assistance do not reduce your casualty loss unless they are replacements for lost or destroyed property.
Loan proceeds used to rehabilitate or replace property do not reduce your casualty loss.
Generally, disaster relief grants, like FEMA assistance received under the Robert T. Stafford Disaster and Emergency Assistance Act, are not included in your income.
You do not reduce your casualty loss by insurance payments you received to cover living expenses if you lose the use of your main home because of the casualty event or government authorities do not allow you to access your main home because of a casualty event or the threat of one. However, if these insurance payments are more than the temporary increase in your living expenses you must include the excess in your income.
Disaster unemployment assistance payments are taxable income.
