James makes good points. You don't even need stakes with the right deadman anchors and guyline knots.
That being said, I've had good luck using either the Groundhogs (when there is very little snow and I can pound them into the ground) or MSR snow stakes. What I've been doing with the MSRs this winter is packing the snow where I'm going to put my stake. Once the snow work-hardens enough, I stick the stake in just like if it were dirt; at an angle away from the tent. I then pack some more snow around it, leaving just a bit of the head sticking up. Once the snow sets, I loop the guyline around it. If done right, it will hold a good amount of tension, albeit probably not as much as a large dead man. If the snow has really frozen solid around the stake, a little thump with my heel knocks it loose and it slips right up and out.
Tarping in the winter takes a bit of effort. If you have snow where you are, I'd suggest practicing staking out your tarp, either using deadman or snow stakes.
Edit: the aluminum snow stakes like the MSRs can work in regular ground. However, if you hit a rock, root, or frozen soil, you can bend them much easier than the Groundhogs.
I know, it's tricky figuring out which stakes to bring during this time of year when you're not really sure how much snow you'll have. But given that there's 18" on the ground now, I'd go for the deadman or MSR's.
These two threads have pictures of tarps I used this winter, using the MSR stakes:
