Tax policy and client planning are intersecting more sharply than ever this week. Retirees are watching the projected Social Security COLA for 2026, while the IRS is set to phase out paper refund checks beginning September 30. Homeowners racing to claim energy-efficiency tax credits may lose their window before year-end. Meanwhile, inflation data will test whether last week’s Fed rate cut was justified. And for service workers, new clarity emerged on how “cash tips” will be treated under the tip‑tax deduction rules.

Here are the five stories worth your close attention this week. 

1. Projected 2.7% Social Security COLA for 2026

CNBC

Though the Social Security Administration hasn’t formally announced the 2026 COLA, analysts expect a 2.7% increase—up from the 2.5% bump in 2025. For the average beneficiary (~$2,008/month), this means roughly a $54/month raise to $2,062.

Advisors should help clients run scenarios accounting for Medicare Part B premium increases, which often offset much of the COLA gain.

2. IRS to Phase Out Paper Refund Checks as of Sept. 30

IRS / Forbes 

In a major shift, the IRS announced it will no longer issue paper refund checks to individual taxpayers starting September 30, 2025, mandating electronic payments for refunds, Social Security, and more under Executive Order 14247. 

This is one of the clearest steps toward a fully digital tax infrastructure. Firms should proactively communicate this to clients and verify banking data before year-end.

This is essentially the final year to claim meaningful federal support for clean-energy home improvements. Clients considering upgrades should aim for completion before December 31 and skilled advisors should help them navigate the PIN requirement.

CNBC

Yahoo News

Treasury officials clarified that casino chips given as tips will qualify under federal “No Taxes on Tips” rules. That definition now expands to cover many nontraditional tip types—mobile payments, checks, even token-based services.

Advisors in hospitality-heavy regions should advise clients in casinos, hotels, and restaurants to document tip flows carefully.

Your Takeaway This Week

Retirees will be watching their COLA, but many will still feel the pinch from rising Medicare and health costs. Homeowners should scramble if they’re planning efficiency improvements—because after 2025, many of these tax credits disappear. The IRS’s shift away from paper checks is paving the way for full digital tax administration. Inflation data this week will either legitimize or challenge the Fed’s recent moves, and tip workers now have clearer guidance on how nontraditional tips are taxed.

All this means your clients face tighter timelines, higher stakes, and a greater need for nimble planning.
