Deposit Interest Retention Tax is the only tax on interest income. The new USC does not apply to deposit interest. Therefore you will have no further tax to pay on your deposit interest.
You may wish to pay voluntary Prsi contributions, if you qualify, to keep up your record with a view to future claims.
