Frequently Asked Questions

Can I request payment by instalments?

We assess the collection stage, the nature of the debt and the requirements for an application. The Tax Authority or Social Security considers the proposal under the applicable rules; submitting a request does not guarantee approval.

Does a complaint suspend collection?

Do not assume collection is suspended automatically. We assess the remedy, suspension requirements and any security or exemption applicable to the case.
