Examples
An x-ray unit for shares above stated value
You run a veterinary practice as an S-corp. On April 3 you transfer into the practice a used digital x-ray unit you bought from a used-equipment reseller for $12,400, and the corporation issues you 50 shares of common stock with a $10 stated value. Debit Equipment $12,400, credit capital stock $500 (50 × $10), and credit capital surplus $11,900. The $11,900 is the stockholder contribution not assigned to capital stock, and both equity lines sit on the balance sheet, not the P&L. In QuickBooks Online, split the journal; do not code the whole $12,400 to capital stock or to veterinary supplies.
A good year is not capital surplus
You run a soap company as an S-corp. After a December wholesale run for a grocery account, the year closes with $14,800 of net income. On January 8 you open the balance sheet and see that amount in earned surplus, leftover profit. That is not capital surplus. Capital surplus only increases when a stockholder pays more than par value or stated value for shares. Do not journal the $14,800 into capital surplus to make equity look cleaner; leave the year's profit in earned surplus so the reports still show what the shop earned versus what owners paid in.
Why it matters
Capital surplus is the part of paid-in capital that is not assigned to capital stock: the excess when a stockholder pays more than par value or stated value for shares. You will not post this most months; it appears when you issue stock or take a stockholder contribution above that assigned amount. Modern reports often label the same extra additional paid-in capital, and it is not leftover profit. If you put the whole contribution on the stock line, or move a good year's earnings into capital surplus, the balance sheet no longer shows who paid in versus what the shop earned, so keep the premium in capital surplus and keep earnings in earned surplus.
