Let's say you're having a three-month job every year, and during those three months, your annual salary is $12*. (i.e. It's not an hourly job, but a full-time job -- you earn $3 during those three months, but the government considers it to be a $12/year job, and taxes you based on that... though you'll obviously get refunded the excess amount at the end of the year.)
During the rest of the year (including right now), you don't have any income.
Now you want to apply for a credit limit increase, which asks for your "annual salary and wages".
(It also has a space for "other income", which is for things like interest, dividends, social security, retirement benefits, etc.)
What should you put ($12, $3, $0?) and where should you put it?
Would the answer be different if you were currently in the three months of employement?
Yes, this is a ridiculous number. :)
