A workers' compensation claim booked at $1,000 today may not fully pay out for fifteen years. Congress does not let the insurer deduct the whole $1,000 now. It deducts the present value, and that single rule drives most of a P&C insurer's tax bill.
A P&C insurer starts from its statutory annual statement, then makes four specific adjustments to reach federal taxable income under Section 832: loss reserve discounting, the revenue offset, proration, and salvage/subrogation. On a growing book, with rising UEPR and rising reserves, each adjustment raises taxable income above statutory income. The adjustments are signed, though. If UEPR falls, the revenue offset subtracts from income. If reserves run off, the unwinding discount makes the tax deduction exceed statutory incurred losses. Check the sign of each change before applying the raises-income shortcut.
Statutory reserves are held at essentially full value. Apart from limited tabular discounting on items like workers' comp lifetime pension cases, they hold the nominal dollars an insurer expects to pay.
Common mistakes
- Deducting the statutory undiscounted reserve. The tax deduction is the discounted reserve, capped at statutory. Deducting the full $6,000 instead of $5,697 in Example 1 overstates the deduction by $303.
- Ignoring the annual statement cap. The deduction is the lesser of discounted or statutory. If a company's own discount produced a number above the statutory reserve, the statutory figure controls.
- Using the pre-TCJA rate. Applying the 60-month federal midterm rate instead of the corporate bond yield curve produces the wrong discount for post-2017 years.
Bottom line
- Section 846 requires discounting unpaid loss and loss adjustment expense (LAE) reserves for tax; the deduction is the lesser of the discounted reserve or the statutory undiscounted reserve (the annual statement cap).
- Discounting accelerates taxable income (more income now), creating a deferred tax asset that reverses as reserves pay out.
- Post-TCJA discount rate is the corporate bond yield curve; pre-TCJA it was the 60-month average of the applicable federal midterm rate.
- Payment patterns are IRS-prescribed by line from industry aggregate Schedule P data, reset each 5-year determination year, using a mid-year payment convention; long-tail lines discount most, short-tail lines barely at all.
Exam shortcut
On a growing book every P&C tax adjustment pushes taxable income above statutory income. Discounting shrinks reserves, the revenue offset adds 20% of the UEPR increase, proration cuts the loss deduction, and salvage reduces losses. The signs flip when the book shrinks: a falling UEPR or an unwinding reserve discount legitimately lowers taxable income relative to statutory. Check the sign of the change before deciding an answer is backwards.
