What a P&L is
A profit and loss statement lists income and expenses over a period. For tax preparation it is usually the full year.
What a useful one includes
- Income grouped by source, not one lump total.
- Expenses grouped into consistent categories.
- The exact period, for example January 1 to December 31.
- The accounting method you use, cash or accrual, if you know it.
Bring supporting items
- Year-end bank and credit card statements for the business.
- A list of equipment or large purchases made during the year.
- Loan statements for business debt.
Common problems
- Personal spending mixed into business categories. See the bookkeeping guide on separating the two.
- Transfers between your own accounts recorded as income or expense.
- A P&L that stops partway through the year.
Do not wait for perfect
A rough but complete P&L now is more useful than a perfect one in a month. Your preparer will flag what needs cleanup.
