Sales and Use Tax Compliance

Since the Supreme Court ruling in South Dakota v. Wayfair, businesses can owe sales tax in states where they have never had a physical presence. If you sell products or digital services, this likely affects you.

What we handle

  • Economic nexus analysis across all states where you sell
  • Sales tax registration in new states
  • Sales tax return preparation and filing
  • Washington State B&O tax compliance
  • Use tax obligations for business purchases
  • Voluntary disclosure agreements for prior exposure
  • Sales tax audit support and representation
  • Product taxability reviews

Who typically needs this

  • E-commerce businesses selling across state lines
  • SaaS companies with customers in multiple states
  • Businesses that recently crossed economic nexus thresholds
  • Companies that have never registered but have been selling into taxable states
  • Washington-based businesses navigating B&O tax classification

Not sure if you have exposure? We do a no-obligation nexus review as part of our initial consultation for tax clients. Many businesses are surprised to learn which states they are already obligated in.

Tax Preparation FAQ

What do I need to provide to get my taxes done?

We send every client a tailored document checklist at the start of tax season. Typically it includes your prior year return, 1099s and W-2s, business income and expense records, and any major transactions. If we do your bookkeeping, we already have most of it.

I am behind on prior year returns. Can you help?

Yes. We handle delinquent returns regularly. In most cases the IRS is more interested in getting current than penalizing, and filing late returns voluntarily puts you in a much better position than waiting to be contacted.

Do you handle extensions, and is that a problem?

Extensions are routine and not a red flag with the IRS. We file them whenever needed. An extension gives you more time to file, not more time to pay, so we make sure any balance owed is estimated and paid by the original deadline.

Can you file in multiple states?

Yes. Multi-state filing is one of our specialties, especially for remote workers, business owners with out-of-state clients, and e-commerce sellers with nexus in multiple states.
