I'll get at least six weeks pay per year of service. I've been there 5.5 years. My current salary is approx €40K.
Lucky you! Been thru the redundancy myself this year, and the gift of money is great. It looks like you'll clear approx €25k (not including statituary, holiday pay, payment in lieu of notice (normally 1 month), etc).
What are the tax implications of this. Is the redundancy tax free?
No, here's an example, but use Clubman's links for exact details: if this is your first time claiming redundancy in the last 10 years, the first €10.5k (approx) is tax free, but the remainder is subject to tax at your marginal rate.
Statituary is tax free, whereas the other payments are not. This is a simplified answer to your q, but all redundancy tax matters should be explained to you in time.
