Asset Purchase Invoices: Receipts and closing statements for major equipment, technology hardware, or business vehicles placed in service during the year. These documents allow the preparer to calculate Section 179 deductions, apply bonus depreciation rules, or establish traditional depreciation timelines.
-
Payroll Tax Reconciliations: Copies of federal quarterly filings (Form 941), annual unemployment filings (Form 940), and state quarterly reports. The wages reflected on the corporate profit and loss statement must reconcile exactly against the total wages reported on payroll tax filings.
