Don't worry. Penalties in such circumstances are tax-geared rather than a specific amount, and (say) 25% of what you owe just wouldn't be pursued by HMRC as a monetary penalty. I don't think you need to complete a self assessment return if this is your only non-PAYE income. Just contact HMRC, tell them that you receive £30 per year in dividends, and they will reduce your tax code accordingly to collect the additional tax. If I remember rightly, the threshold for having to go into self assessment is £500 additional income I think, but don't quote me on that.
