Below are the most frequently asked sales tax questions we receive. If your situation isn’t covered here, book a free consultation and we’ll walk you through it personally.
Sales tax nexus means you have a sufficient connection with a state that requires you to collect and remit sales tax there. Nexus can be triggered by physical presence (like an office, employee, or warehouse) or economic presence (exceeding sales or transaction thresholds).
👉 Not sure where you have nexus? Our Nexus Analysis service can identify your exposure before states come knocking.
You’ll likely need to register for sales tax in each of those states and begin collecting accordingly. Because every jurisdiction has different requirements, My Sales Tax Firm helps you manage multi-state registrations accurately and efficiently — avoiding costly errors or delays.
Filing frequency varies by state and sales volume — monthly, quarterly, or annually. States typically assign your filing frequency after registration. We handle filing schedules for clients nationwide so you never miss a due date.
Absolutely. Our team manages filings for clients in every U.S. state where they’re registered. We gather your sales data, prepare and file your returns, and ensure payments are submitted on time — freeing you to focus on your business.
It’s not enough to simply collect exemption certificates — you must verify they’re accurate, up-to-date, and valid for each transaction. My Sales Tax Firm reviews, tracks, and maintains your certificates to ensure compliance and avoid costly audit findings.
Invalid or missing certificates can result in back taxes, penalties, and interest. Our exemption certificate management process includes periodic reviews and validation so you stay protected.
Don’t panic — but don’t ignore it either. Notices can be triggered by late filings, mismatched data, or missing payments. My Sales Tax Firm engages directly with state departments to resolve notices and represent you during audits.
The best prevention is accuracy and consistency — ensuring proper nexus evaluation, registration, filing, and recordkeeping. Our ongoing compliance monitoring and notice management help minimize audit risk.
Not necessarily. Marketplaces like Amazon and Etsy may collect and remit sales tax on your behalf — but only for sales made through their platform. You may still have obligations for sales made via your website or other channels. We can review your setup and confirm what still needs your attention.
Digital products and SaaS are taxed differently across states. Some treat them as tangible goods; others exempt them. Our sales tax experts specialize in multistate SaaS tax research and can help you determine where and when to collect.
