The time tax offices take to process your tax return will usually last between three and twelve weeks. However, it can vary more widely, too, particularly if there is a high number of returns being processed. The time also varies between tax and revenue offices.
If you have been waiting for longer than twelve weeks, however, an enquiry to your tax office is in order. Thanks to the three-digit tele-number, which you can find on your tax return, the tax office will be able to locate your return more quickly.
