Frequently Asked Questions
Direct answers on scope, timelines, support, and documentation for this service.
What is sales tax nexus?
Nexus is a connection between your business and a state that creates a tax obligation. It can be physical (office, warehouse, employees) or economic (sales volume or transaction count in a state). We help identify where you have nexus obligations.
Do I need to collect sales tax for online sales?
Most states now require sales tax collection for online sales if you have economic nexus in that state. We analyze your sales data by state to determine your filing obligations and ensure compliance.
What platforms do you work with for sales tax?
We work with all major e-commerce platforms including Shopify, Amazon, Etsy, WooCommerce, and BigCommerce. We can integrate with sales tax automation tools or manage filings directly based on your needs.
How do I register for sales tax in multiple states?
We handle multi-state sales tax registration for you. After analyzing your nexus obligations, we register your business in each required state, set up filing schedules, and ensure you're collecting the correct rates in each jurisdiction.
What happens if I didn't collect sales tax but should have?
You may still owe the tax plus penalties and interest. We help with voluntary disclosure agreements to minimize penalties, get compliant, and set up proper collection going forward. Ignoring the issue only makes it worse.
How often do I need to file sales tax returns?
Filing frequency depends on your sales volume in each state—monthly, quarterly, or annually. Higher-volume businesses file more frequently. We manage your filing calendar to ensure all deadlines are met across all states.
Do marketplace facilitators collect sales tax for me?
In most states, marketplaces like Amazon and Etsy collect and remit sales tax on your behalf for sales on their platforms. However, you may still need to file returns for sales through other channels. We help you understand your obligations.
What is the New York sales tax rate?
NYC sales tax is 8.875% (4% NY state, 4.5% NYC, 0.375% MCTD). Other NY locations vary. We ensure you're collecting and remitting the correct rates for every jurisdiction where you have nexus.
Can you help with a sales tax audit?
Yes, we represent businesses in sales tax audits by state authorities. We gather documentation, respond to auditor requests, negotiate settlements if needed, and work to minimize additional assessments and penalties.
What records do I need to keep for sales tax?
Keep records of all sales transactions, exemption certificates, tax collected by jurisdiction, and documentation of tax paid on purchases. We help set up proper record-keeping systems and retention policies to stay audit-ready.
