Rules and decisions to review
- Use dedicated business banking and a consistent bookkeeping process. Identify owner contributions, draws and loans separately from sales and expenses.
- Choose an accounting method and chart of accounts appropriate to the business. Track unpaid bills and customer balances when relevant.
- Review federal, state and local obligations, including estimated income tax, sales tax, payroll and information returns where applicable.
- Keep equipment and startup-cost records rather than assuming every initial purchase is immediately deductible. Federal tax classification may differ from the legal business label.
A practical example
An owner depositing personal savings into the business should record an owner contribution or documented loan as appropriate, rather than sales income. The classification affects financial reports and tax preparation.
Records to gather
Gather formation documents, EIN notice, banking records, startup invoices, owner funding records and projected revenue and costs.
Your next step
Set up the books and a recurring reconciliation schedule before transaction volume grows. Identify each tax account and responsible person, then prepare an initial cash-flow and estimated-tax projection.
