What does a revenue recognition change do to state apportionment and sales tax?

The short answer
Three different things, through three different doors. For state income tax timing, a book revenue recognition change matters to the extent it changes federal taxable income, through the accounting method change that implements it and the federal rule tying income inclusion to the financial statements, and states follow that federal result unevenly, on their own conformity schedules. For apportionment, the change reaches the sales factor directly: reslicing contracts among performance obligations, regrading arrangements between gross and net presentation, and moving receipts between years all move the factor, sometimes more than they move income. For sales and use tax, the change does nothing by itself, because sales tax attaches to transactions rather than to book revenue, but the same contract analysis that drives the accounting change routinely redesigns the invoices, and sales tax follows the invoices.
Why the question arises
The question arrives attached to an accounting project rather than a tax one: an adoption of the revenue recognition standard, ASC 606, a restatement, a billing model change, or a new contract structure that moves when and how revenue is recognized. The accounting team has decomposed the contracts into performance obligations, allocated the transaction price, and decided who is principal and who is agent. The state tax work does not begin from scratch; it begins from those workpapers, because every state consequence traces to one of three features of the accounting answer: when revenue is recognized, how much of it is presented gross rather than net, and how the contract price is divided among components.
The income tax door: timing through conformity
Book timing changes state income tax only through federal taxable income. The mechanics run through a federal accounting method change, with the catch-up adjustment spread under the federal rules, and through IRC Section 451(b), which provides that an accrual taxpayer with an applicable financial statement cannot recognize income for tax later than it is recognized in that statement. States then split. Rolling conformity states absorb the federal timing rules, and the method change adjustments, as a matter of course. Fixed-date states conform to the Internal Revenue Code as of a chosen date, and a state whose date precedes the federal rule never adopted it: California, conformed to the Code as of January 1, 2015, is the standing example, so an item accelerated into federal income by the financial statement rule can require a state subtraction, and the same contract can carry three different revenue streams, book, federal, and state, each on its own clock. The catch-up adjustment deserves its own line in the state workpapers, both because spread periods and conformity interact and because a multiyear adjustment computed on federal numbers does not simply drop into a state return that never conformed to the change.
The apportionment door: the factor moves with the contracts
The sales factor is built from receipts, and the accounting exercise changes receipts in three ways that have nothing to do with income. Timing first: receipts that move between years move the factor of both years, and in transition years the factor can swing while income barely does, which matters wherever the factor feeds throwback computations, market sourcing schedules, or the receipts-based thresholds of economic nexus statutes. Presentation second, and this is the one that decides real dollars: the principal-or-agent conclusion determines whether an arrangement runs through the statements, and typically the returns, at the gross amount or at the net fee, and a regrading from gross to net can shrink factor denominators and numerators by the full pass-through volume, changing apportionment percentages in every state at once and dropping receipts below thresholds they previously exceeded, or the reverse. Composition third: allocating the transaction price among performance obligations reslices a single contract into components that source differently, tangible property by destination, services by market or by performance, and licenses under the intangible rules, so the same total revenue can produce a different numerator in most states purely because the slices changed. A factor built by rolling forward last year's sourcing conventions over this year's resliced revenue is the standard error in the first return after the change.
The sales tax door: the invoices, not the revenue
Sales and use tax is indifferent to book revenue: the liability attaches transaction by transaction, on the timing the state's own statute supplies, and recognizing revenue earlier or later moves no sales tax obligation anywhere. What moves sales tax is what the accounting project does to the transactions themselves. Decomposing bundled arrangements into performance obligations is, functionally, a taxability study the accountants performed for their own reasons: it identifies the software, the services, the maintenance, and the property inside each contract, which is exactly the analysis needed to decide what is taxable where. Whether the invoice then itemizes those components or states a single price decides real liability in the many states that tax an unseparated bundle whenever any component is taxable. The principal-or-agent conclusion carries over too, because who sells is the first question of who collects. And the systems consequence is the quiet one: a new revenue engine and a new billing structure mean the mapping between invoice lines and the tax engine's decisions was rebuilt, and the time to retest it is before the first billing cycle rather than during the first audit. Gross receipts regimes deserve a closing caution: the Washington, Ohio, Texas, and Oregon entity-level taxes each define and time their receipts under their own rules, some leaning on federal amounts and some not, so the change flows into each of them separately rather than once.
Practice notes
The state workplan writes itself from the accounting workpapers. First, take the performance obligation inventory as the map: every state question, sourcing, taxability, gross or net, traces to a line of it, and duplicating the contract review is wasted motion. Second, reconcile three ledgers by state: book revenue, federal revenue, and each state's revenue after conformity modifications, with the catch-up adjustment stated separately, because examiners in nonconforming states start from the gap. Third, rerun the thresholds in the transition years: economic nexus, filing obligations, and throwback all key on receipts levels that the change may have moved in either direction. Fourth, treat the invoice redesign as a sales tax project with its own sign-off, since the taxability of a bundle is decided by how it is billed, and the billing was just rebuilt by people optimizing for something else.
