I just need to know how my husband and I should complete our W4 now that we are married and plan on filing jointly.
2) If you want a refund on your Joint return, you should each claim 'Married, but withhold at higher single rate', and max of two exemptions.
putting a zero under total allowances (line 5) is OK, but may withhold more than you intend if you are submitting new W-4 forms to both employers.
IF you are doing this on only one of your W-4 forms, a zero is OK. IF you are submitting a new W-4 to both employers...perhaps a "1" on both (on line 5) will split the difference.
Remember that it will only be affect your withholding for for the remainder of the year. (And, you need to pay attention to your paystubs to ensure the change was implemented...when you submit...ask payroll/HR about which paycheck they think it will start)
When you file early next year, you can check out your refund situation and re-adjust at that time.
When Rainman12 suggested using no more than 2 allowances...(He might correct my assumption) but he referred to line 5 on the W-4. That's considering everyone in your family including the 2 kids.
Unless you have a ton of other income (Self-employment/cash, interest, Dividends, significant capital gains) then using the married but single rate, and 2 allowances should give you some refund...using a 1 would be more...but really, we can't know your total income and deduction situation for the year.
Start with the married but single rate, and 1 or 2 allowances on line 5 of the W-4, then re-adjust next year (if needed) when you file your tax return for 2017 and determine whether too much, or too little was withheld from your combined pay during the year.
First, if you and your husband live together, he cannot be Head of Household. You file a joint return. By filing as “Married Filing Jointly” you will each get the $4050 personal exemptions and the standard deduction of $12,600 for a married couple.
You can file a joint return even if one of the spouses had little or no income.
