Tax Credits

I only recently returned to Ireland and began wotk a month ago. I received my tax credit cert from revenue and it was on a week 1 basis with a monthly cut off point of €2,450 before I was taxed at 42%. I called them and said I wanted my credits for the 5 months I hadn't worked here, so they sent me a new cert but the monthly cut off point was still €2,450. Payroll said they can only go on what is on the cert. How can I claim my full credits?

How can I claim my full credits?

Call them again.

Go on the cumulative basis (Instead of Week one). Unused cut off and tax credits should then balance out.

As explained above you will actually get a rebate every month as you will not have reached the year to date figure for higher bracket. Payroll should be able to explain this and how it works to you.
