Taxes
Debt payment plan (installments)
In short
An agreement with the tax office or EFKA to pay your debts in monthly installments.
If you owe money to the tax office or EFKA, you can ask to pay it in many installments. Each month you pay part of the amount.
Installments usually come with interest. The more installments you have, the smaller each monthly payment, but you often pay more in total.
If you miss installments, the plan can be cancelled. So first work out how much you can really pay each month.
