I think this is mostly a US thing. Why use yearly salary? You're not paid once a year, are you? Most likely once a month. Referencing monthly salary makes much more sense.
"I'm making 50k". Great, now I have to guess - dollars? Monthly? Yearly? If yearly then what's the monthly paycheck? Net? Gross?
Please elaborate on the 14 salaries? I'm in Canada, I would guess at most I could claim 3. My occupation, the rebates I get from the federal government, and the rebates from the provincial one would amount to my 'income' each year.
My bad, I didn't get notified someone replied to my comment and only just checked. As mentioned below in this thread, I meant we get 14 monthly salary payments, where "months" 13 and 14 are less taxed and are tacked onto a summer and winter month as a holiday and christmas bonus, respectively.
