Investment Banking Accounting Interview Questions & Answers

Accounting interview questions in investment banking test whether you understand how the three financial statements connect, not whether you memorized definitions. Expect a mix of walkthrough questions (how a line item flows through the income statement, cash flow statement, and balance sheet) and standalone accounting concept checks (deferred taxes, working capital, goodwill). Wall Street Prep and other IB prep resources treat this as the foundation of week one interview prep, before valuation ever comes up. This hub collects 17 accounting interview questions asked in real IB interviews, grouped by topic, each with a model answer you can deliver in under a minute.

What accounting knowledge do IB interviews actually test?

IB accounting interviews test whether you can trace one transaction or line-item change through all three financial statements and land on a balanced result. Interviewers care less about textbook definitions and more about mechanical fluency: can you move fast, stay consistent, and explain why the balance sheet balances. Most interviewers work through a fixed order: income statement, then cash flow statement, then balance sheet. For the full baseline walkthrough before you tackle individual questions, see how to walk through the financial statements in an interview and how the three statements link together.

Three-statement mechanics questions

How do the three financial statements link together?

Net income flows from the income statement into the cash flow statement as the starting line, and the cash flow statement's ending cash balance flows onto the balance sheet. Retained earnings on the balance sheet also updates by net income minus dividends. Any non-cash item on the income statement, like depreciation or stock-based compensation, gets added back on the cash flow statement. This closed loop is what interviewers are checking when they ask "walk me through the three statements": they want to see you understand the linkage, not just recite each statement in isolation. See the full income statement, balance sheet, and cash flow statement breakdown for each statement's structure.

If a company records a $5 million revenue sale on credit, what happens?

Revenue and net income rise by $5 million, less tax, on the income statement, but no cash has changed hands, so accounts receivable rises by the same amount on the balance sheet. On the cash flow statement, net income is added, then the increase in accounts receivable is subtracted as a use of cash in the operating section, netting cash flow back toward zero from that transaction. This tests whether you understand accrual accounting: revenue is recognized when earned, not when cash is collected. Once the customer pays, receivables fall and cash rises, with no further income statement impact.

The $10-of-depreciation walkthrough

Walk me through how $10 of depreciation affects the three statements

Assume a 25% tax rate. On the income statement, depreciation expense rises by $10, pre-tax income falls by $10, and net income falls by $7.50 after tax. On the cash flow statement, start with the $7.50 drop in net income, then add back the full $10 of depreciation because it's a non-cash charge, giving a net increase in cash from operations of $2.50. On the balance sheet, net PP&E falls by $10 from the extra depreciation while cash rises by $2.50, so total assets fall by $7.50. On the other side, retained earnings falls by $7.50 to match the lower net income, so the balance sheet still balances. This is the single most common walkthrough question in IB accounting interviews, and interviewers use it to see whether you keep a consistent order under pressure.

What if the company doesn't pay cash taxes that period?

If cash taxes aren't actually paid because the company has a loss carryforward or other tax shield, the same $10 of book depreciation still reduces net income by $7.50 for accounting purposes, but the cash tax savings might be deferred rather than realized immediately. That gap between book tax expense and cash taxes paid is exactly what creates a deferred tax asset or liability, which is the natural follow-up question interviewers ask next.

How would a higher tax rate change the answer?

A higher tax rate means a bigger drop in net income for the same $10 of pre-tax depreciation, since more of it gets taxed away before it hits the bottom line. But the depreciation add-back on the cash flow statement stays fixed at $10 regardless of the tax rate, so cash from operations is always higher than net income by the after-tax value of the depreciation add-back, not by the full amount. Candidates who forget this and add back the full $10 to a lower net income overstate the cash impact.

Working capital questions

How do changes in working capital affect cash flow?

Working capital, defined here as current assets excluding cash minus current liabilities excluding debt, ties up cash when it rises and frees cash when it falls. An increase in accounts receivable or inventory is a use of cash because the company has spent money or delivered goods without collecting cash yet. An increase in accounts payable is a source of cash because the company is delaying its own payments. In a DCF, rising net working capital is subtracted from free cash flow every period, which is why a fast-growing but unprofitable-on-cash company can look strong on the income statement while burning cash. See working capital: accrual vs cash accounting explained for the mechanics.

A company's receivables grow faster than its revenue. What does that signal?

Receivables growing faster than revenue signals the company is having trouble collecting from customers, extending more generous payment terms to win business, or possibly recognizing revenue too aggressively. Days sales outstanding, receivables divided by revenue times 365, is the metric to check first. A rising DSO alongside flat or declining revenue growth is a red flag interviewers expect you to name unprompted, since it often precedes a cash crunch even when the income statement still looks healthy.

Deferred tax questions

What is a deferred tax liability and how is it created?

A deferred tax liability is a balance sheet entry representing tax the company will pay in the future because it recognizes income or expenses on a different schedule for book purposes than for tax purposes. The most tested scenario is an asset write-up in an acquisition: the buyer marks the target's assets up to fair value for book accounting, but the tax basis of those assets carries over unchanged. That mismatch means book depreciation exceeds tax depreciation for years, so the company reports lower taxable income for tax purposes than for book purposes early on, and the difference accrues as a DTL that reverses over the asset's useful life.

How do you calculate the deferred tax liability from an asset write-up?

The formula is straightforward:

DTL = Asset Write-Up × Tax Rate

If a target's PP&E is written up by $40 million and the tax rate is 25%, the DTL created is $10 million. This DTL then amortizes down over the useful life of the written-up asset, as book and tax depreciation converge back toward each other.

What's the difference between a deferred tax asset and a deferred tax liability?

A deferred tax asset means the company will pay less tax in the future, typically because it has recognized an expense for book purposes before it's deductible for tax purposes, like a net operating loss carryforward or certain accrued liabilities. A deferred tax liability means the company will pay more tax in the future, typically from accelerated tax depreciation or an asset write-up in an M&A deal. Both sit on the balance sheet and both reverse over time as the book-tax timing difference closes.

Goodwill and writedown questions

What is goodwill and where does it come from?

Goodwill is the excess of the purchase price paid in an acquisition over the fair value of the target's identifiable net assets. It captures brand value, synergies, and everything the acquirer paid for that isn't a discrete tangible or intangible asset. Goodwill is not amortized under US GAAP; instead it's tested at least annually for impairment, and if the reporting unit's fair value falls below its carrying value, the company must write goodwill down.

Walk me through a goodwill impairment of $100 on the three statements

On the income statement, the impairment of $100 is recorded as a non-cash expense, reducing pre-tax income and net income by $100 (goodwill impairment is typically not tax-deductible, so there's usually no tax shield). On the cash flow statement, net income falls by $100, but the $100 is added back as a non-cash item, so cash from operations is unchanged. On the balance sheet, goodwill falls by $100 on the asset side, and retained earnings falls by $100 on the liabilities and equity side, keeping the balance sheet in balance. No cash actually moves.

Why would a company take a goodwill impairment?

A company takes a goodwill impairment when the business it acquired is worth less than it paid for it, usually signaled by a sustained stock price decline, a missed integration, lost customers, or a downward revision to the unit's projected cash flows. It's a backward-looking accounting cleanup, not a cash event, but it's a signal analysts watch closely because it often means management overpaid or the deal thesis didn't play out.
