Recording Non-Taxable Dividends

[Richard Ryder]

Can anyone suggest how I should record stock/mutual fund dividends that 
are reinvested within (U.S.) tax-deferred retirement accounts? Increases 
in the number of shares in such investment accounts do not result from 
present income. The income is only realized when taxable distributions 
are paid from the accounts. Gnucash may not care about the distinction 
between taxable and non-taxable income, but I don't want to have the 
income counted twice, once when the dividend is posted and again when 
the money is withdrawn (and the IRS wants it reported as "income").
