6.5 Deferred Tax — Assets, Liabilities, and Why They Exist
The idea in plain words
Sometimes accounting rules and tax rules count the same item in different years. Deferred tax is the bridge between the profit in the accounts and the profit the tax authority sees. A deferred tax liability is tax postponed, often because of faster depreciation for tax. A deferred tax asset is future tax relief, often from losses. US rules reduce doubtful assets with a valuation allowance, while the international and Indian standards recognize only the amount that is probable.
Key points
■A $100 million machine expensed for tax in year 1 and depreciated over five years in the books creates a $16.8 million liability at 21%.
■That deferral is an interest-free loan: worth $2.68 million today at 8%.
■US losses arising after 2017 carry forward indefinitely but offset only 80% of taxable income a year.
A closer look
A company’s reported profit (calculated under accounting rules) and its taxable income (calculated under tax law) are almost never identical, because accounting standards and tax authorities frequently treat the same transaction differently, especially in its timing. Deferred tax exists purely to reconcile this timing gap.
Decision rule
Strip valuation-allowance releases and charges out of earnings before applying a P/E: they are one-time, non-cash and reflect a judgment about the future, not this year’s operations. If the effective tax rate differs from the statutory rate by more than about 5 percentage points, read the rate reconciliation before forecasting. Treat a deferred tax liability from continuing investment as long-dated, near-equity financing; treat one from a single asset sale or a reversing timing item as debt due on the reversal date.
The costliest mistake
Capitalizing a tax benefit as if it were operating profit. Tesla’s reported 2023 net income was $15.00 billion; $5.93 billion of it, 39.5%, was the valuation allowance release. Apply any earnings multiple to the reported figure and 39.5% of the resulting value rests on a one-time accounting event; at an assumed 50× P/E that is about $297 billion of value. Avoid it by valuing on pre-tax operating income, or on net income with the release removed.
6.6 Inventory and Depreciation Method Choices
The idea in plain words
Choosing how to value inventory and how long assets last changes a company’s profit from year to year without changing its cash. When costs are rising, LIFO, which is allowed only under US GAAP, reports the lowest profit and the lowest tax. Changing the assumed useful life of equipment can move billions of dollars of profit for the largest companies. Nothing in the bank changes; only the accounting story does.
Key points
■On the same purchases, FIFO showed a 47.5% gross margin and LIFO 42.5%.
■FIFO inventory = LIFO inventory + the LIFO reserve; analysts convert before comparing peers.
■The LIFO conformity rule ties tax use of LIFO to its use in reports to shareholders.
A closer look
Two further accounting choices, individually minor but collectively important for comparing companies, deserve explicit attention. Inventory costing (FIFO — First-In-First-Out — versus weighted-average cost, since LIFO is IFRS-prohibited as noted in 6.1) determines which cost layer is matched against revenue when inventory is sold, materially affecting reported gross margin during periods of significant inflation. Depreciation method — straight-line (equal expense every year) versus accelerated methods (larger expense in early years) — changes the timing of when an asset’s cost hits the income statement, without changing the total amount depreciated over the asset’s full life.
Decision rule
When peers use different inventory methods, convert the LIFO reporter to FIFO with its LIFO reserve before comparing margins or inventory turns; skip the step if the reserve is below about 1% of inventory. When a company lengthens useful lives, recompute the year’s earnings at the old lives and treat the difference as non-recurring for valuation. As a check, if depreciation falls as a share of gross property while capex rises, look for a life change in the notes.
The costliest mistake
Treating earnings lifted by a useful-life extension as operating improvement. Amazon’s 2024 change added $2.5 billion to net income with no change in how the servers performed. Capitalized at an assumed 30× earnings, that is $75 billion of value resting on an estimate the company partly reversed a year later. Avoid it by valuing on cash flow after capex, which no depreciation estimate can change.
