Sales Tax Wasn’t Supposed to Be Your Job
Fifty states, more than 11,000 tax jurisdictions, each with its own tax rates, rules and deadlines. And somehow, it’s all landed on your desk.
The truth is sales tax is boring. It’s also one of the few boring things that if you’re not careful, can quickly grow into an expensive tax liability. Dull but dangerous, and exactly why it shouldn’t stay your problem.

A Closer Look At Our Sales Tax Services
Inside our sales tax filing services
Our filing services include economic nexus tracking, unlimited transactions for your online business, clear updates on where things stand with each state, access to our tax software, and an assigned consultant who knows your account. Tax returns are included throughout the year, with transparent pricing for anything else.
Inside our registration and exemption services
Our tax registration services cover every state where you need to collect, with clear guidance through the process and turnaround faster than industry averages. Exemption services check whether you qualify to stop paying tax you don’t owe, then advise you through what’s needed to apply.
How our VDA services work
We assess your historical tax exposure, advise honestly on whether a Voluntary Disclosure Agreement is the right route, and guide you through the process with the state, typically kept anonymous in the early stages, to reduce penalties and limit the lookback period. VDA work typically completes within two to six months once started.
Tax services for every ecommerce platform
Whether you sell on Amazon, Shopify, eBay, Etsy, Walmart, WooCommerce, BigCommerce, or your own store, our tax services plug into how you already work, with platform-specific tax guidance included.

Reuben
Founder Reuben Mattinson never set out to build a tax company. He was a science teacher who started to sell online, expanded into the US and hit the sales tax wall. After a paid consultation with an accountant that didn’t teach him anything he couldn’t have found himself, he decided to learn it properly himself. Solving his own problem turned into helping other founders with theirs, and RJM grew from there.
Jared
Reuben’s close friend since childhood, Jared joined as the business scaled. Different backgrounds but the same belief about how people should be treated: be straight with them, know your stuff, charge a fair price and, if you don’t know the answer, say so.
That belief runs through the whole company. It’s why historically 50% net profits have been donated to Hope for Justice, a charity fighting human trafficking. And it’s why, as RJM grows, one thing stays constant – every client can reach someone who knows their account and get a real, human answer quickly. Today RJM’s tax experts work with businesses across all fifty states and US tax is still all they do.

“Avalara was such a nightmare and I was so stressed because of how they were not filing properly. RJM corrected all their mistakes and made the transition painless for me. It was such a weight off my shoulders to know that the sales taxes were getting filed and paid properly. I would recommend RJM to anyone that files sales taxes.”

“US sales tax felt like a minefield, especially with registrations in multiple states, but they broke it all down, told us exactly what needed to happen, and then just got it done. Thanks to RJM, US sales tax has gone from a constant worry to something we barely have to think about.”

Resources to Keep You Ready
The businesses that come to us early, save money, time and stress. The ones who come to us late spend all three.
Most founders don’t think about compliance until they have to, and fixing a tax problem always costs more than preventing one. The goal: audit ready, exit ready and properly tax ready.
Our helpful guides cover the real questions online sellers ask, from marketplace facilitator tax rules to what to do when a tax notice lands. Selling on Amazon, Shopify, eBay, Etsy, Walmart or WooCommerce? We’ve written platform-specific sales tax guides for each so you can make the right plans from day one.
