My current withholding status is HH. Filing this year was a bit awkward. Currently married but husband currently serving life sentence. I was able to file HH because of child depend. This year no child dependent but have parent dependent (does not meet HH requirements). Only option was to file MFJ which is ok but didn't want to go this route wanted to go MFS. Question not sure whether to change my payroll withholding to married or married filing separately.
If you are going to file separately, you should have taxes taken out that way. If you did file Married Filing Jointly, you would get twice the deduction that you do separately, but that is your decision.
If your intention is to have more money withheld from your paycheck, you would claim single.
This would not prevent you from claiming any other status on your tax return.
If you prepare a W-4 for your employer, you can have additional taxes withheld.
On Step 4 Line (c) Extra Withholding. Enter any additional tax you want withheld every pay period.
