The pension deadline is closer than you think

If you file a tax return, a contribution made before the ROS deadline can still be set against last year’s income. It is the only point in the year where you can reduce a tax bill you have already run up.

Work out your headroom now, not in November.

A contribution paid and elected before the deadline can be set against last year’s income.

Cap €115,000

Most tax planning has to be done before the money is earned. Pension contributions are the exception, and it is a genuinely useful one.

If you are self-employed, a proprietary director, or anyone else who files a Form 11, you can make a pension contribution now and elect to have it set against last year’s income. The relief comes off a bill you have already run up. Nothing else in the Irish system works quite like that.

The dates that matter

0131 October is the paper filing deadline.
0218 November is the extended deadline if you both pay and file through ROS.

To backdate the relief, the contribution has to be paid and the election has to be made by the relevant date. Both. A payment on its own does not do it, and this is where people come unstuck.

How much you can put in

Relief is limited to a percentage of your earnings, and the percentage rises with age: 15% under 30, rising through the bands to 40% from 60. It is calculated on earnings capped at €115,000.

So somebody aged 45 earning €90,000 can get relief on up to €22,500 for the year. At the higher rate that contribution costs them €13,500 after relief, and €22,500 lands in the pension.

Three things that go wrong

01Leaving it to the last week. Providers need time to process, and elections need to be filed properly. Late October is busy for everyone. September is not.
02Paying but not electing. The election is a separate step and it is the one people miss.
03Guessing the limit. Paying in above your age-related limit does not get relief this year, and the excess sits there doing less for you than it should.

If you are on PAYE

This particular deadline is mostly about people who file returns. If your contributions come through payroll, relief is usually given at source as you go. It is still worth checking whether you have headroom, and whether your employer would match more than you are currently paying in.
