Your refund will be the current value of your contributions, less 20% tax, regardless of what rate of tax relief you got on your contributions. There's an opportunity for some people to use the tax relief to boost the value of the refund if they're paying tax in the new job at 40%.
Example...
- Value of your contributions to the old scheme €10,000
- Less tax at 20% €8,000
- Put another €5,333 out of your own savings to this and make a contribution of €13,333 to your current employer's scheme
- Claim 40% tax relief on €13,333 = €5,333 tax relief
- Amount gone into the pension scheme: €13,333. Net cost to you €8,000 which was the net refund you received.
This only works if you are paying tax at 40% now and have the scope to make a contribution of €13,333 over and above whatever contribution you're already making.
