IRS Pub 505, worksheet 2-8, which does the tax calculation for each annualized period when CG and/or QD have been received, specifies that both the CG and QD numbers are to be scaled by the appropriate scaling factor to calculate the annualized tax for each period. It doesn't matter if CG is a one time event or whether QD or CG is recurring, rather it is done to correctly calculate the annualized tax for that period using the correct tax rates for regular and CG/QD income in that period. TT is not following the IRS requirements to properly calculate Form 2210 line 14 (a)-(c) when capital gain income is included.
