There is no discussion I can find on how often you need to pay yourself. Everything I find, just says if you are profitable, you must pay yourself a reasonable wage. So, once a year, or throughout the year will work as long as it is paid, and it is reasonable wage for work preformed.
Below are a couple articles that may be helpful.
"The IRS will not object to the SCorp
making zero payments to the owner employee when the business is earning
little or no income. But, when the business is making money, it must first pay the
owner-employee a reasonable compensation before making any payroll tax-free
distributions with any excess funds."
For additional information click on, S
Corp pays zero salary to owner.
"an S corporation must pay reasonable employee compensation (subject to employment taxes) to a shareholder-employee in return for the services the employee provides before a distribution (not subject to employment taxes) may be given to the shareholder-employee."
