I had this problem a few years ago. Unless they've changed, QRs said that up to 75% of monthly net pay can be recovered from a singly and 50% from married. I ended up getting paid nothing for 2 months in a row so I'd advise speaking to whoever does your pay after the pay's been calculated but before the pay run happens so they can see what you're due to get. I think the pay run is on or about 16th of the month so call between 10-12 of the month and get them to check while they can still do something about it.
