Income taxes in Ohio - the argument for Married Filing Separately

After getting married in May of 2010, this will be my first year filing my income taxes as anything other than single.

In an effort to reduce my tax burden, I evaluated the options of both Married filing Jointly, and Married filing seperately.

Every where I read, from FreeTaxUSA.com to turbotax.com , the repeated message is that it is rarely in your best interests to file separately.

If you live in Ohio - rethink this.

You can find the tax tables for 2004-2012 here.
For 2010

Ohio Taxable IncomeTax Calculation
0 – $5,0500.618% of Ohio taxable income
$5,050 – $10,100$31.21 + 1.236% of excess of $5,050
$10,100 – $15,150$93.63 + 2.473% of excess over $10,100
$15,150 – $20,200$218.52 + 3.091% of excess over $15,150
$20,200 – $40,350$374.62 + 3.708% of excess over $20,200
$40,350 – $80,700$1,121.78 + 4.327% of excess over $40,350
$80,700 – $100,900$2,867.72 + 4.945% of excess over $80,700
$100,900 – $201,800$3,866.61 + 5.741% of excess over $100,900
More than $201,800$9,659.28 + 6.24% of excess over $201,800


Doing these calculations for a combined income of 80k, 100k, and 160k shows that it is clearly a marriage penalty in Ohio to file Jointly:
