DDH’s Sales and Use Tax Services
DDH’s work is focused and simple: help businesses by providing state-by-state use and sales tax consulting services. Whether you’re trying to get compliant, respond to a notice, or stop guessing, the objective is the same – clarity you can act on. Sales tax rules change by jurisdiction, and gaps can become big distractions.
Services and Specialities
DDH provides sales tax advisory services that start with the realities of your operation: where you sell, what you sell, and how tax is handled in your systems. Engagements often include:
- Audit support and state communications
- Nexus reviews are core sales and use tax services (post-Wayfair)
- Voluntary disclosure and remediation planning
- Filing process improvements and team training
Practical, specific, and tailored services.

Quick Services FAQ
Do you only help with audits?
No. DDH supports proactive compliance and sales tax consulting services, nexus questions, refund opportunities, and research-backed positions – then steps in if an audit notice arrives and timelines get tight.
What should a business prepare before reaching out?
Bring:
- A list of states where you sell or ship
- Information about how you invoice/collect tax today
- Any notices, filings, or prior advice
That’s usually enough to start narrowing exposure.
Can software replace sales and use tax services from consultants?
Software can calculate and file, but it won’t interpret grey areas, defend your facts, or negotiate with states. That’s why sales tax advisory services, provided by experts, are so important.
How fast can you help if we just received a notice?
Often immediately. DDH can help you triage deadlines, communicate with the state, organize support for key positions (taxability, exemptions, sourcing, nexus), and build a clean response package so the audit stays controlled.
Can you help if we have past exposure or missed filings?
Yes. DDH helps quantify exposure, prioritize risk by state, and map remediation via sales and use tax services (voluntary disclosure or other resolution paths) while also tightening processes so the same issues don’t recur.
