For me its 2 years, which is crazy, imagine someone getting away with that in the UK or Germany etc good old Ireland.
The NTA would rather fine us for harmless things like letting our licence expire(while not working).
Are you confessing? 
im thinking of giving it a go, when you think about it, its a great gig, under cut legit taxis so you have plenty of work, no NCT and suitability test every 6 months, no 2,000 + euro insurance, no income tax, no 10 or 15 year rule, no passengers reporting you to the NTA. No NTA OR guards that will bother their ass to catch you.
