These include outstanding or overdue living expenses such as rent payments, utility bills and debts.
For long-term debt, such as mortgages or student loans, only the non-interest or principal portion of the upcoming lunar year's worth of payments can be deducted.
If payments are not being paid on the long-term debt, then the debt is not deducted from your Zakatable assets.
Interest payments are not considered deductible liabilities for the purpose of Zakat calculation (whether short-term or long-term). It is recommended to prioritize repayment of all interest-bearing debt.
Note: Your upcoming living expenses not related to debt repayment are not deducted as liabilities. These include upcoming rent payments, bills, food, fees, etc.
