Permanent life insurance—whole life and universal life—combines a guaranteed death benefit with a cash-value account. For years, ultra-low interest rates squeezed these policies.

Insurers struggled to credit returns high enough to support guarantees, product menus shrank, and premiums on remaining options crept higher. Many shoppers settled for term insurance or postponed buying altogether.

What changed

A tax-code update revised how life insurance is tested for tax advantages under Section 7702. Instead of assuming a fixed 4% interest rate—a relic of the 1980s—the rules now use a variable benchmark tied to prevailing yields. Practically, that lowers the hurdle insurers must meet and expands how much premium a policy can accept without turning into a modified endowment contract (MEC).

Why it helps

When the assumed rate was stuck at 4%, carriers had to design policies as if they could always earn that level. In a low-yield world, that math strained guarantees and forced tighter funding limits. The new variable assumption better matches reality. Insurers can price with less stress, and policyholders can typically fund more cash value per dollar of death benefit while keeping full life-insurance tax treatment.

Maureen Shaughnessy, an actuary, said that lower interest-rate assumptions allow a policy to hold more cash value and accept higher premiums for the same amount of death-benefit coverage.

Cash value boost

More favorable funding space can improve early cash accumulation potential, especially for designs aimed at long-term tax-advantaged growth. Owners may be able to front-load premiums, build liquidity faster, and create wider cushions against policy lapse. For business and estate strategies—buy-sell plans, executive bonus, or legacy funding—this added flexibility can be particularly useful.

Easier issuance

The friendlier test also reduces pressure on carriers to curtail offerings. Expect broader product shelves: more whole life dividend options, additional universal life chassis (including accumulation-focused and protection-focused designs), and underwriting programs that lean on accelerated, no-exam processes where appropriate. Fewer surprise premium hikes and less product “whiplash” are likely outcomes.

Availability timing

Rule changes don’t flip products overnight. Carriers need to refile, recalibrate illustrations, and coordinate administration systems. Many did phased rollouts, with refreshed contracts and updated illustration software arriving in waves. If a quote looks materially different than last year’s, the updated testing framework may be a key reason why.

Who benefits

Households seeking lifelong coverage plus tax-efficient savings gain options that were previously cramped by 4% assumptions. Small-business owners funding key-person coverage or future buyouts can better balance death benefit and cash accumulation. High earners who have maxed out qualified plans may find permanent policies more accommodating as part of a diversified, long-horizon strategy.

Key mechanics

Two IRS tests govern life-insurance tax status: the Guideline Premium Test (caps on funding relative to death benefit) and the Cash Value Accumulation Test (minimum “corridor” between cash value and face amount). The new variable rate eases both. Result: a larger safe harbor for premium deposits and fewer accidental MECs—so long as funding stays within the policy’s updated limits and schedules.

Tax advantages

Permanent policies retain their core benefits: tax-deferred growth, tax-free death benefit to beneficiaries, and the potential to access cash value via withdrawals to basis and policy loans without current income tax (if managed properly). The revised rules don’t create new tax perks; they make it more feasible for policies to qualify for existing ones in a low-rate world.

Important caveats

A more flexible policy isn’t automatically better. Overfunding too aggressively can still trigger MEC status, which changes how distributions are taxed. Policy loans accrue interest and, if unmanaged, can erode values or cause lapse with tax consequences. Dividends in whole life are not guaranteed; indexed or fixed universal life crediting depends on carrier performance and caps.

Pricing reality

While the tax test is friendlier, guarantees still cost money. Expect premiums for strong, guaranteed protection designs to reflect today’s mortality assumptions, expenses, and capital requirements. Compare multiple A- or better-rated carriers, and look at long-term sensitivity—how projections behave if dividends fall, caps are trimmed, or loan rates rise. Resilient designs matter more than rosy illustrations.

Underwriting trends

Accelerated underwriting has expanded—more applicants can qualify without a paramed exam, based on electronic health data and prescription histories. That can shorten the process and reduce friction. Still, face amounts, age, and health history determine whether full labs are needed. The new rules don’t waive underwriting; they make issuing competitive policies economically viable again.

Smart shopping

Start with purpose: pure protection, cash accumulation, or a blend. Decide on chassis—whole life (guarantee-heavy, dividend-driven), universal life with secondary guarantees (lifetime protection focus), fixed or indexed UL (flexible cash growth), or variable UL (market exposure). Stress-test illustrations with lower crediting or dividends, higher loan rates, and slow-funding scenarios. Verify conversion options, loan provisions, and riders.

Bottom line

A technical fix has improved the design math for permanent life insurance by aligning tax testing assumptions with prevailing yields and widening funding flexibility. The opportunity can be meaningful, but long-term results still depend on disciplined design choices, strong carrier selection, and ongoing policy monitoring.
