Hi, does anyone know if it is possible to direct revenues choice as to whether they put you on a Week/Month 1 or Cummulative PAYE tax basis?

This is in relation to non-residents who havn't worked as a PAYE employee in Ireland before, and will only be staying on a short term locum contract. I have a feeling that the tax basis will be directed by the information entered on the Form 12A - Application for Tax Credits.

I am trying to avoid a Week 1 basis in preference for the Cummulative basis.

Can anyone help?
Thanks.
