Updraught is spot on!
During 2004/2005 tax year I worked 7 months in SA and the rest out of the country. I submitted the form with the IRP5 for the time worked in SA and a letter to say that I had been working outside the contry for the rest of the time. They sent me a letter requesting IRP5's for the rest of the year. So I sent another letter explaining that I had been employed out of the country for the last 5 months of the year with dates and details. A few months later I got what I paid in back.
Yip filled in the form myself too for free.
If I remember correctly it says on the form that you could be asked to prove your claim of having worked outside the country for the required amount of time.
So Don't chance your arm!!!!
