Dublin66, Thanks for your help.
A few more questions arise, if you have a few minutes.
My holding is 616 shares. Dividend rate is 7.05p (sterling), so dividend payable is GBP£43.42.
What do you mean by "net amount of the dividend"?
Also, the voucher mentions that this has a GBP£4.82 tax credit. What does that mean and does it only apply for the purposes of UK revenue?
Based on the figures above, what would i enter in box 24 of form 12?
I guess that submitting info on a dividend in 2012 may prompt questions about a dividend in 2011, 2010, 2009 etc, so i guess it is best to make a full disclosure now. Do i just write them a letter detailing all of the dividends that i have received from Vodafone or how should i proceed with the years before 2012?
