Map facts before assuming a filing obligation.
List the legal entities, existing registrations, employee and contractor work locations, property, customer locations and services performed. Note when each fact changed. Physical activity and economic activity may matter differently for different taxes, and protections or exceptions require their own analysis.
For example, Pennsylvania explains that an employee working in the state can create corporate income-tax nexus, subject to the applicable facts and protections. That example is not a nationwide rule or a determination for your entity. CTAS confirms the states and issues it can accept before an engagement.

Separate nexus, sourcing and apportionment.
Nexus concerns whether a jurisdiction has a sufficient connection to require an obligation. Sourcing concerns where an item or receipt belongs under the relevant rule. Apportionment concerns how a tax base is divided. Those questions should not be collapsed into a single client-address test.
Bring contract and delivery facts rather than only a list of invoices. A state may use a different approach for service receipts, owner income or a different tax. The review needs the applicable year and entity treatment; it does not assume every state follows federal rules.
Review payroll and owner obligations separately.
A remote employee may raise withholding or unemployment questions as well as income/franchise-tax issues. Residency, where services are performed and any relevant reciprocal or convenience rules need review. Payroll-provider setup should follow the analysis rather than substitute for it.
Pass-through businesses may also face owner-level estimates, nonresident withholding or entity filings. Pennsylvania’s pass-through guidance illustrates why company and owner responsibilities need a separate checklist. Federal, state and municipal rules are distinct.

Turn the review into a responsibility map.
Identify which registration, tax filing, payment or payroll steps are recommended, who will perform them and what deadlines apply. Legal qualification to do business is different from tax registration and may require counsel. Voluntary disclosure or past nonfiling requires specific advice; no blanket cure is promised.
A CTAS engagement may define a focused review or coordinate accounting and tax information. It does not promise every state return, sales-tax service, payroll account or legal registration. Where specialist advice is needed, agree that boundary before implementation.
Prepare a useful first conversation.
Describe the change, locations involved, entity and time period without sending confidential employee or tax records in the initial inquiry. Gather prior returns and notices, payroll work-location reports and a chronology for the subsequent agreed transfer method.
The objective is a supported decision about obligations and next steps, not a claim that remote delivery removes state taxes. See our industry pages for the accounting context and our planning page for a broader owner decision.
Questions before the next step.
Does a remote business avoid state tax obligations?
No. Location and activity facts can matter even without a customer-facing office. The relevant jurisdiction and tax type need review.
Will CTAS file in every state?
No universal state-filing promise is made. The engagement must identify the jurisdictions, forms and responsibilities CTAS accepts and where another adviser is needed.
