Why would my wife's pension be taxed at a different tax rate than my pension when filing a joint return. Both pensions are about the same value, mine has a federal tax rate of 27% and my wife (who doesn't work) is at 37%. I thought that since we are filing jointly, both would be based off of the combined earned income and be taxed at the same 27% tax rate. Note: we live in TX, so there is no state tax involved and the combined earned income with the pensions did not cross into the upper tax bracket.
