US Sales Tax
US Sales Tax Compliance & Filing Services
Your business needs you, not endless tax paperwork. We’ve built a comprehensive sales and use tax compliance playbook to help your business expand into the US market, so you can manage US sales tax compliance with ease.
What’s included in our US sales tax service
We handle the full US sales tax lifecycle so remote and international sellers stay compliant across every state they sell into:
- Nexus evaluation: we determine where your sales create an obligation to register, by state.
- Multi-state registration: we register your business for sales tax in each state where you’ve established nexus.
- Sales tax return filing: we prepare and file your returns on time, in each state’s required format, and remit the tax owed.
- Rate accuracy: we apply the correct combined state and local rates for every jurisdiction you sell into.
- Deadline monitoring: we track filing and remittance dates across states, including local returns where required.
- Advisory and risk review: we assess backdated exposure, voluntary disclosure agreements, and the most cost-effective path to compliance.
Multi-state nexus management
The hardest part of US sales tax is that obligations shift as you grow. Once your sales cross a state’s economic nexus threshold, you must register, collect, and remit sales tax there, and the thresholds, rules, and rates differ in every state.
We manage nexus for you end to end: monitoring where you’re approaching or have crossed a threshold, registering you in the right states at the right time, and keeping you compliant as your footprint expands. No guesswork about where you owe, and no surprise liabilities building up in states you didn’t know you’d triggered.

FAQ
It breaks into a few critical steps: evaluating your nexus status in each state of interest, registration, reviewing the correct sales or use tax rates, accurate tax calculation, and filing returns with remittance of tax. We manage each step for you.
Once registered, remote sellers must submit returns and remit owed taxes to each state’s authority. With customers across states you face different rates, calculations, remittance and submission periods, and even different return file formats, with some states also requiring a local return. Building and maintaining that scheme in-house is costly and time-consuming, which is why most non-US remote sellers use a third-party provider.
Yes. The principal focus of our advisory and accounting services is the e-commerce and digital services sector, and we have significant practical experience across all regions. We always welcome partnerships that enhance our services and open new opportunities for clients.
Yes. Our tax and reporting team works with many clients based in the EU who ship goods to different US states and sell through multiple online channels. We handle registration and filing on your behalf.
The first step is evaluating your turnover in those states. Once we’ve determined where and from when you should have registered, we run a risk assessment covering backdated registration, voluntary disclosure agreements, and ongoing compliance costs. In some cases the cost of backdated registration is far higher than a state’s annual fines, so the right path depends on your specific exposure.
