What's the difference between current tax expense and deferred tax expense components?

Question

Total tax expense = current tax + deferred tax. Each component tells a different story about the firm's tax position. Current tax expense represents taxes legally owed on this year's taxable income — the amount flowing to the tax authority (net of timing). It equals taxable income times the statutory rate, adjusted for credits. Deferred tax expense captures the change in net DTL during the period. A positive deferred tax expense means DTLs grew (or DTAs shrank) — the firm is deferring more tax to future periods. A negative deferred tax expense (credit) means DTLs declined or DTAs grew. For Helvica Pharma: - Current tax $312M = high cash taxes paid this year - Deferred tax -$25M = net DTL declined by $25M The negative deferred component suggests either (a) prior-period DTLs reversing as assets fully depreciate, (b) new DTAs created from R&D capitalization or NOLs, or (c) tax rate changes reducing DTL book values. Cash tax rate = $312M / pretax income = useful for FCF modeling. Effective tax rate = $287M / pretax income = reported in the P&L. ```mermaid flowchart LR A[Pretax Income] --> B[Current Tax
$312M] A --> C[Deferred Tax
-$25M] B --> D[Total Tax
$287M] C --> D ``` Analysts should reconcile the current-deferred split year-over-year to spot earnings management, especially around DTA valuation allowances.
