January filing season reveals what the rest of the year hides. For many CFOs, it is the first time sales and use tax stops looking routine and starts behaving like a material operational risk.
Sales Tax
January filing season has a way of collapsing assumptions.
For most of the year, sales and use tax feels manageable. Returns are filed. Payments are made. Variances exist, but they appear contained. Nothing suggests urgency.
Then filing season hits.
Suddenly finance teams are reconciling numbers that do not align across systems. Tax teams are fielding questions they cannot answer quickly. Leaders are asking why sales tax by state reports do not match the general ledger and why explanations rely on manual work instead of data.
This is not because something went wrong in January. It is because January forces everything into view at once.
Filing season does not create sales and use tax problems. It exposes how well or poorly the organization actually controls a system that touches every transaction, every revenue stream, and every jurisdiction in which it operates.
For CFOs and senior leaders, that distinction matters.
Sales and use tax rarely breaks in obvious ways. It breaks quietly.
A new state crosses an economic nexus threshold, but registration lags.
A product or service changes, but taxability rules are not updated everywhere.
Marketplace sales follow different logic than direct channels.
Manual overrides close small gaps and slowly become standard practice.
Each decision feels reasonable in isolation. None trigger alarms. Over time, they compound.
Because sales tax applies at the transaction level, even small inconsistencies repeat thousands of times. Filing season aggregates those repetitions. A sales tax audit formalizes them.
This is why audit exposure often surprises leadership. The risk did not appear suddenly. It accumulated invisibly.
Sales and use tax is still treated in many organizations as a compliance function. File accurately. File on time. Move on.
Auditors do not see it that way.
A sales tax audit evaluates whether tax logic is applied consistently across systems, time, and transactions. It tests whether exemptions are supported by documentation. It examines whether use tax is accrued systematically or handled ad hoc.
When inconsistencies appear, auditors expand scope. When scope expands, sales tax audit penalties grow quickly across multiple periods and jurisdictions.
Filing season is often the first internal signal that these inconsistencies exist.
The most important question for leadership is not whether returns were filed. It is how difficult it was to file them.
If filing required spreadsheets, last-minute adjustments, or explanations based on individual memory rather than system logic, the organization is already absorbing operational risk.

Sales tax audit penalties are visible and measurable. Interest, assessments, and back taxes get attention.
The larger cost is disruption.
Finance teams shift from forward-looking analysis to reconstructing history. Close cycles slow. Forecasts lose precision when historical tax data cannot be trusted without explanation. Leadership time is diverted from decision-making to remediation.
Revenue can be distorted when tax treatment varies across channels or periods. Cash flow is affected by unexpected liabilities or unrecovered overpayments.
Sales and use tax becomes a distraction rather than a controlled process.
This is why filing season matters. It reveals whether sales tax is operating as a system or as a series of workarounds.
Sales tax automation is often framed as a way to save time. That framing misses the real value.
Effective sales tax automation and sales and use tax automation create consistency. They centralize tax logic. They apply rules uniformly across sales channels and systems. They tie exemption certificates directly to transactions. They ensure use tax is addressed within procure to pay, not after the fact.
When filing season arrives, automated environments spend less time reconciling and more time validating. Variances are explainable. Data is traceable. Filing becomes confirmation rather than reconstruction.
Automation does not remove accountability. It removes guesswork.
For CFOs, that shift fundamentally changes how sales tax audits unfold.
The most effective way to assess sales and use tax risk is immediately after filing season, while the friction is still visible.
Hesitation on these questions is not a failure. It is a signal that operational discipline has not kept pace with complexity.
Sales and use tax complexity is increasing. States are using more data. Audit cycles are accelerating. Tolerance for inconsistency is shrinking.
CFOs who continue to treat sales tax as a filing exercise will continue to encounter surprises. CFOs who treat it as an operational system governed by discipline, documentation, and automation will not.
Filing season is the moment when that difference becomes visible.
