When the company I worked for screwed up my withholding causing me to owe $2700, I was outraged. They had changed my dependents. They just said it was my responsibility to make sure they were withholding enough, not theirs. Even though I had turned in the proper W-4.

Luckily I made a mathematical error on my 1040 EZ so I only paid in $200 on tax day. That would give me 7 months to raise the $2500 before they found my error and required payment without penalty or interest. Even more luckily the IRS never found the error. Kept an extra $2500 in the bank for 7 years just in case I was audited and they found the mistake.
