EBS 9 month fixed rate 3.52% AER

Forgive my ignorance

EBS have a 9 month fixed AER rate of 3.52% a gross rate of 3.50%.

So lets say one deposited 100k in it at 3.50% thats 3,500 gross interest ater 9 months. Is the only deduction to that Dirt tax?

No this is not correct. The rate is 3.52% Per Annum not for 9 months. You get it pro rata.

Ok so you would get 2.64% gross
