There are basically two options that will result in your employer withholding more from each paycheck:
- Change the filing status on your W4 from Married Filing Jointly to Single (it's ok to do this even if you file a joint tax return)
- Increase the amount of the additional withholding that you've requested be withheld from your paychecks each pay period
After doing this, I recommend checking your paystubs to be sure that the changes have taken place. You should also do some quick calculations to ensure that the increased amount is going to get you close to what you are anticipating for your refund.
