Frequently asked questions

What's new in 2026 vs 2025?

401(k) deferral limit rises to $24,500 (was $23,500). Standard deduction is $16,100 single / $32,200 MFJ. Social Security COLA is 2.8%. SS wage base is $184,500. HSA limits rise to $4,400 self / $8,750 family. Estate exemption is $15M under the OBBBA.

Where does this data come from?

The IRS Revenue Procedure 2025-32 and related notices, plus the SSA's annual COLA release. Every leaf page links to its primary IRS source. Last verified within 7 days of IRS announcement.

Do these numbers apply to my state taxes?

No — these are federal-only. State income tax brackets, sales tax rates, and state-specific deductions live on the per-state pages under /state-calculators/.

When will 2027 numbers be official?

The IRS typically releases the following year's adjustments in October–November. Until then, our /2027/ pages show projected estimates based on expected ~3% inflation adjustments, clearly marked as projected.

Why is there a TCJA sunset warning on the estate tax page?

The 2017 Tax Cuts and Jobs Act doubled the estate exemption through 2025. The 2026 figure reflects the One Big Beautiful Bill extension; if it's repealed, the exemption could revert to roughly half. Estate planning calculators flag this scenario.
