1. Check whether you already have an owner's equity account. Go to Settings, then Chart of accounts, and look for something like "Owner's Investment" or "Owner's Contribution" under the Equity category. QuickBooks creates a basic Owner's Equity account by default for sole proprietors and single-member LLCs; for a partnership or multi-member LLC, you typically want one equity account per owner.
2. Create the equity account if it doesn't exist. Select New, choose Equity as the account type, and pick Owner's Equity (or Partner's Equity, or Member's Equity, depending on your business structure) as the detail type. Name it for the specific owner if you're tracking contributions separately.
3. Record the contribution as a deposit. If the owner wired or deposited cash directly into the business bank account, use + New, then Bank deposit. Select the bank account the money landed in, and on the deposit line, choose the owner's equity account instead of an income account.
4. For a non-cash contribution, use a journal entry instead. If the owner contributed an asset, like equipment, rather than cash, use + New, then Journal entry. Debit the asset account for its fair market value, and credit the same owner's equity account.
5. Confirm it on the Balance Sheet, not the Profit and Loss. A correctly recorded contribution shows up as an increase to equity on the Balance Sheet. If it's showing up as income on the Profit and Loss instead, it was posted to the wrong account and needs to be corrected.
