*Loan,banking and credit>>>income tax

If I go ahead and have my wedding this year instead of next will i get more back on income taxes?

If you are filing a joint return with your spouse, and your spouse has no income, then you will be paying less taxes due to the increased standard deduction and additional exemption.

If your spouse has children, and no income, you will get an even bigger refund.

If you and your spouse have comparable incomes and no children, then you are going to owe about the same tax whether you were married or not.

If you were low income, filing as head of household with a child, and you married someone with higher income, it is possible that you will owe additional tax because you lose the Earned Income Credit.

So you could owe less taxes, the same, or more.

you will never get more back...you will have a wife
That depends on too many things that you didn't specify. When you get married, you might pay less in taxes or you might pay more. If your fiancee doesn't work and you have a large income, then you would very likely pay less.
Not necessarily. Getting married will allow you to file a joint return with your new spouse. Whether or not you'll get anything back or you'll have to pay at the end of the year will depend upon your combined tax liability and how much was withheld from your combined wages.
