Sales tax registration, filing, and audit help

What the sales tax process looks like
We begin with the states, filing periods, sales channels, products or services, deadlines, and current account status. The written engagement identifies the jurisdictions and work included before registration, filing, notice, or audit-support services begin.
ANTICIPATED DELIVERABLE
From registration facts to the first sales-tax return
The accepted engagement identifies the states, accounts, periods and services included, with a clear handoff from registration to filing.
| Stage | Work product | Responsibility |
|---|---|---|
| Registration facts | Activities, jurisdictions and accepted registration application. | Client confirms business facts; Tavella prepares applications included in scope. |
| Account setup | Filing-frequency and start-period review. | Confirm account information, portal access and the responsible filer. |
| Record reconciliation | Taxable-sales, marketplace, tax-collected and payment reconciliation. | Client provides records; Tavella identifies accepted adjustments and open questions. |
| First and recurring returns | Prepared returns and filing/payment steps for accepted periods. | Identify who reviews, authorizes, submits and pays; recurring work requires an agreed scope. |
Taxability treatment, registration coverage in every state, penalty relief and agency outcomes are not guaranteed. Notices, audit-support periods, legal work, bookkeeping and historical corrections are separately identified.
Your engagement identifies the items included. Additional years, entities, states, corrections and advisory work are agreed separately.
COMMON QUESTIONS
Questions about sales tax services for small businesses
Do I need to collect sales tax in every state where I have customers?
Not necessarily. A state may consider physical activity, economic activity, what is being sold, where the sale is sourced, and how the sale is made. Rules and thresholds differ by state, so the review must be based on the specific jurisdictions and facts.
If a marketplace collects sales tax, do I still have to register or file?
Possibly. Marketplace rules differ by state, and direct sales or other business activity may still create registration or reporting requirements. The applicable states and sales channels need to be reviewed before a conclusion is reached.
Can Tavella CPA Group register my business and file the returns?
Registration and filing may be available for the jurisdictions and periods accepted in a written engagement. Availability depends on the facts, deadlines, records, platform access, and applicable authorization requirements; coverage in every state is not promised.
Can you help with late returns, notices, or a sales tax audit?
Potentially. The first step is reviewing the jurisdictions, periods, account history, notices, deadlines, and available records. Past-due filings, historical cleanup, notice responses, and audit support are scoped separately, and no penalty relief or agency outcome can be guaranteed.
What records are helpful for a sales tax review?
Common records include sales by state and channel, invoices, marketplace reports, tax collected, exemption certificates, filed returns, payment confirmations, product or service descriptions, and information about employees, inventory, locations, and events.
How do I upload documents?
After engagement setup, use the secure client portal and the upload instructions provided by Tavella CPA Group. Do not send Social Security numbers, tax returns, bank information, or other sensitive documents through the public contact form or ordinary email.
Is this service cloud-based?
Yes. Organizers, secure document uploads, messages, electronic signatures, invoices, and final documents can be handled online through the appropriate secure workflow.
How long will preparation take?
Timing depends on the service, complexity, completeness of the information provided, filing deadline, and current availability. Expected timing is discussed when the scope is confirmed; submitting a consultation request does not reserve a filing deadline.
What happens if information is missing?
Tavella CPA Group will identify the missing items and explain what is needed next. Preparation or filing may need to pause until the required information is received, and any deadline or extension options will be discussed based on the circumstances.
Is audit or notice representation included?
Only when representation is expressly included in the written engagement. Audit, examination, and notice-response work are otherwise reviewed and scoped separately.
