Start with the completed financial statements

Accounting profit is the starting point for a tax reconciliation, not necessarily the final taxable amount. Give the preparer the trial balance and supporting adjustments used to finish the books. Explain unusual items and prior-year corrections. The tax calculation then identifies where accounting treatment and tax rules differ, rather than replacing the financial statements with an unexplained tax number.

Keep permanent and timing differences traceable

Depreciation, limited deductions and other adjustments can affect the reconciliation in different ways. Retain schedules so later years can be prepared consistently. Do not change the books simply to make profit equal taxable income without understanding the accounting entry. A clear reconciliation allows the owner to see why a profitable year can produce a different tax base.

What to gather before the review

• Final financial statements and trial balance
• Asset and expense detail supporting adjustments
• Prior-year tax reconciliation and carryforward schedules

Does a low bank balance prove the corporation had no taxable profit?

No. Cash, accounting profit and taxable income measure different things. Loan repayments, asset purchases and other movements can reduce cash without matching the year's deductible costs.

Your next step

Provide the detailed ledger behind the financial statements so adjustments can be explained rather than guessed.
