Buzz matter of fact I have heard of the marriage penalty...fact is that I was single first, then married, then married with kids...its a typical progression thing ya know
The "marriage penalty" was first enacted on the books clear back in the late 60's under the premise that two people together could live (guess they hadn't been to my house) more cheaply than two indivdiuals. The logistics have been changed back and forth numerous times over the years based mostly on AGI (adjusted gross income) and additional relief to totally phase out the so called penalty in expected for tax year 2005 (but that legislation will run out again in 2011 I believe). A-N-Y-W-A-Y....
The "penalty" depends soley upon if there are two wage earners in the house or one. Fact of the matter is if you each earned $40K per year as a (no kids) married couple filed jointly you are indeed "penalized" about $1500 (1.9% AGI) compared to be single
but if you are a sole wage earner (one spouse doens't work) with the same total AGI of $80K you would actually benefit in tax breaks by about $4200 (5.26% AGI).
And now we bring to an end Acctng. 101!
Sooooo basically its a mixed bag overall and though we originally planned for the population decreasing two (as per 1_pointer) resource gobblers, chit happens and number three appeared and I'll take the moral, ethical, and financial responsibility for that little toe-head the rest of my life
(Still would like that flat tax though!!)
