The payment plan does not prevent credits in the tax system from being offset against claims included in the payment plan.
Credits, e.g. for interest tax rebates, child benefits or value added tax, are to be set off according to law. Any payment made this way is not considered a payment according to the payment plan. Payments according to the payment plan are still expected, unless the set-off results in the debt being paid off.
