Should I change my W-4 form now from Single to Married Filing Jointly? I got married in June of this year and forgot to update the form.

There are only two days left in the current tax year (and one pay period).  I'm not sure what I should do.

It's too late to do anything for 2018. It will all get straightened out when you file your 2018 tax return.

You should give your employer a new W-4 for 2019. After you get your first paycheck in 2019, you can use the Withholding Calculator on the IRS web site to figure out what to put on your W-4 form. The IRS Withholding Calculator is at the following link.
