Longer, even.Keep until you claim the State Pension.
This is what I did, fortunately, as I needed them recently when selling my house in order to get a Certificate of Exemption from NPPR (Non-Principal Private Residence) Charge by showing that I resided in the property during the years 2011, 2012 and 2013 - Revenue documentation is one of the acceptable forms of proof.Scan and save a digital copy.
We had a request during lockdown from an ex-employee of a former client company which had gone out of business 15 years earlier. They were really anxious for confirmation of their employment for 2 particular years as they badly needed the PRSI credits for a pension claim. We were delighted to find an old file and confirmed the employment particulars in a brief letter which the DSP happily accepted. Had that information been destroyed in the meantime, the worker would have lost out.I have all my p60s since I started working and I would say every tax return copy from the old manual days! They don't take up that much space.
On a similar another note I am helping someone at the moment who is due a small work pension since January, however they were asked by the company for p60 or other proof of income for 2006/07/08, they happened to have 06/07 but not 08 as I suspect they were unemployed for end of year, anyways still waiting for letter or some documentation as proof of income from Revenue. When I did manage to get through by phone I was told I had to put that request in writing and send to particular dept which I did with copy letter from pension provider, not a sign of a reply since! Keep you own records if you can.
I though I had everything back to 2000 but recently found the prior ones in a folder going all the way back to my first P60 for 1976 ! First payslip is also there.I have all my p60s since I started working and I would say every tax return copy from the old manual days! They don't take up that much space.
You beat me by a few years, think my first one is 1979 or 80I though I had everything back to 2000 but recently found the prior ones in a folder going all the way back to my first P60 for 1976 ! First payslip is also there.
