100% Bonus Depreciation Is Permanent Again, and Your Business Clients Are Deciding Right Now

The estimated-tax deadline just reminded every business owner of the new rules

The second-quarter estimated tax payment for 2026 fell due on Monday, 16 June 2026, the business day after the 15 June date that landed on a weekend. For millions of pass-through owners that quarterly cheque is the moment they actually think about tax, and this quarter they are thinking about it under a tax code that changed underneath them.

The One Big Beautiful Bill Act rewrote the core business deductions, and 2026 is the first full year owners are planning around the new versions. Three numbers matter most. One hundred percent bonus depreciation is permanent again for qualified property acquired on or after 20 January 2025, reversing the phase-down that would otherwise have cut the rate to 20 percent in 2026 and zero in 2027. The Section 179 expensing cap rose from 1 million dollars to 2.5 million dollars, with the phase-out starting at 4 million dollars. And the 20 percent qualified business income deduction for pass-throughs was made permanent, with a new minimum deduction of 400 dollars for active owners who have at least 1,000 dollars of qualified business income, beginning in 2026.

That is a different planning environment than the one most owners assumed they were in a year ago. This post is about what that shift is worth to your CPA firm, and what it costs you if a competing firm explains it first.

What changed for your clients

For two years the planning advice on equipment and assets carried a ticking clock. Bonus depreciation was scheduled to fall, so the conversation was about racing the phase-down. That clock is gone. With 100 percent bonus depreciation permanent and the Section 179 cap at 2.5 million dollars, a profitable business can now write off most qualifying equipment, vehicles and improvements in the year it is placed in service, on purpose and as a repeatable strategy rather than a one-time scramble.

The pass-through picture changed too. A permanent 20 percent qualified business income deduction removes a major source of uncertainty from entity choice, owner compensation, and multi-year income planning. Decisions that owners deferred while the rules were temporary, such as whether to buy now or next year, how to structure a purchase, and whether the current entity still fits, are live again. Mid-year is exactly when those decisions get made, which is why the June deadline and the new rules collide at a useful moment.

The opportunity for CPA firms

Every uncertain owner is a search query. They are typing things like "is bonus depreciation still 100 percent in 2026," "Section 179 limit 2026," and "QBI deduction permanent" into Google and into AI assistants. They are asking whether to buy equipment this year, how the deduction affects their estimated payments, and what the changes mean for their entity. The firm whose page answers those questions, with current figures, is the firm that earns the call.

This is acquisition, not just compliance. A proactive tax-planning engagement is among the most valuable and sticky relationships a CPA firm holds, and it pulls the rest of the work with it. The owner who trusts you to time a 2.5 million dollar equipment purchase brings the returns, the payroll questions, and the next entity. The same dynamic we described for tariff-driven CPA advisory applies here: a federal change creates a wave of owners who suddenly need guidance and are actively shopping for it.

To capture that demand, the operational side matters. The right systems shorten the path from enquiry to engagement, and we have catalogued the free tools for US accounting firms in 2026 and the free AI tools for US accountants in 2026 that firms use to handle the volume. The strategy that connects them is set out in the pillar guide to digital marketing for accounting firms.

The opportunity cost of staying quiet

Here is the hard half. Demand this concentrated does not wait for you. If your firm has no current page on the new depreciation and QBI rules, or a stale one written under the old phase-down, the searching owner does not see you. They see whichever firm treated the law change as a content event. That firm collects the planning engagement, the returns, and the multi-year relationship, and you never learn the lead existed.

The cost is concrete. A planning engagement plus the recurring compliance work behind it is a five-figure relationship over its life, often more as advisory deepens. The price of inaction is rising on the client side too: for returns required to be filed in 2026, the minimum penalty for failing to file more than 60 days late is the smaller of the tax due or 525 dollars, which is one more reason owners are looking for a firm that keeps them ahead of deadlines. Win a handful of those relationships across a planning year and the gap between acting and staying quiet is a measurable line in next year's revenue.

It compounds because rankings are sticky. The firm that publishes early, earns links, and gathers engagement signals while owners are researching builds authority that is expensive to displace. By the time a quiet practice notices the calls going elsewhere and commissions a page, the better-optimised competitor has months of indexing and trust ahead of it. In search, late is not simply late, it is structurally behind. We made the same case in our look at the IRS and AI-driven audits.

Visibility is the deliverable, not the afterthought

Technical competence on bonus depreciation and QBI is assumed. Any qualified firm can run the calculation. What separates the firms that grow from this law change from the ones that merely keep up is whether an owner can find them at the moment the decision is in front of them.

That is a marketing problem with concrete parts. It means a fast, well-structured page targeting the exact phrases owners use, which is the work of search engine optimization. It means that page loading instantly and converting a reader into an enquiry, which is the work of website design and development. And it means using AI automation to respond and qualify before the lead cools. A page that ranks but does not convert is as costly as no page at all.

The decisions clients will bring you this quarter

Owners are not searching in the abstract, they are searching for their own decision, and a page that names those decisions ranks and converts. The recurring questions this quarter are concrete. Should I buy the equipment now that 100 percent bonus depreciation is permanent, or spread purchases for a steadier deduction. Does my planned vehicle or build qualify as bonus-eligible property. Should I use Section 179 or bonus depreciation, given the 2.5 million dollar cap. Now that the 20 percent QBI deduction is permanent, does my current entity still fit. How do these deductions change my estimated payments for the rest of the year.

Each of those is a page section, and each maps to a service line your firm already sells. The firm that lays the answers out plainly, with the permanent 100 percent rate, the 2.5 million dollar Section 179 cap and the permanent 20 percent QBI deduction stated clearly, signals competence before the first call. That is the difference between an owner who books a consultation and one who keeps scrolling to a competitor. The content does the qualifying for you, so the leads that reach your team are warmer and closer to engaging.

What to do this week

Publish or refresh one authoritative page on the 2026 rules, aimed at the profitable owner deciding whether to buy, how to structure it, and what their entity should be. State the permanent 100 percent bonus depreciation, the 2.5 million dollar Section 179 cap, and the permanent 20 percent QBI deduction in plain terms. Answer the questions owners are actually asking.
