Hi there! I'm getting married next month and I am wondering about my future spouse's benefits. She has been receiving domestic partner benefits through my employer and I have been paying tax on the fair market value of the benefits as imputed income. I understand that when I go to file, my 'married' filing status will be good for the whole year (a good thing). Is this also true of the imputed income? Will I be eligible for a refund of the whole year's withholdings on the imputed income, or will I just stop paying tax on the imputed income next month and lose the money I've paid so far?

Thanks!
