A side business that begins with trays of food for a community gathering can quickly become an enterprise with orders, delivery fees, ingredient costs, and payments arriving through three different apps. Around Rainier Beach, Hillman City and Columbia City, entrepreneurs selling prepared foods or catering events need a way to tell business income from reimbursements and personal transfers. This is an illustrative business scenario, not a claim about any named local operator.

Start with a calendar-year folder. Divide income into cash sales, card transactions, third-party delivery payments and deposits for future events. Keep copies of platform statements, because the amount deposited after processing fees can be lower than the gross amount actually sold. Reconcile the statements to your register and bank account each month.

For expenses, sort ingredients, packaging, market fees, permitted kitchen use, fuel, equipment, advertising and contractors into separate categories. Record who was paid and what was purchased. Keep receipts for the original transaction; a single bank withdrawal rarely establishes whether the purchase was eligible or was partly personal.

The Internal Revenue Service allows businesses to use any reliable recordkeeping system that clearly shows income and expenses, but the records must support items reported on returns. That includes invoices, receipts, bank deposits, refunds, mileage documentation when applicable, and records of payments to workers.

Washington's business and occupation tax is generally based on gross receipts rather than net profit. Seattle operates a separate municipal tax and business-licensing system; its 2026 B&O threshold changed, but a business that owes no city B&O tax may still need to file. Do not assume a low-profit year erases state, federal, or city responsibilities.

A vendor who sells across Beacon Hill, Georgetown and Rainier Valley should also identify the location where each taxable activity occurs and confirm the appropriate city and state classifications. Food sales and services are not all taxed the same way. Ask the tax authorities or a qualified professional about the specific transaction instead of applying one rule to every order.

Before meeting a preparer, create a summary of total sales, discounts, refunds, sales tax collected, cost of ingredients, inventory on hand when relevant, contractor payments, and any payroll. Note missing receipts and uncertain transactions. A transparent preparer should explain what additional documentation they need before promising a deduction.

The practical goal is not a giant stack of receipts in January. It is a repeatable recordkeeping routine that helps a neighborhood business understand what it earned, what it spent, and which questions still need professional answers.
