How to handle filing taxes in 30 different states as a small business
Hey everyone, I'm struggling with a major tax headache for my small company. We're a team of 4 people who provide specialized consulting services across the US, traveling to about 20-30 states annually. Our accounting firm just dropped a bomb on us - they're threatening to drop us as clients unless we start filing state taxes in EVERY state where we do work. Back in 2022, we had a big project in Colorado that lasted several months. We did file taxes there as required, but it turned into a complete nightmare. We got hit with penalties after the project ended because we didn't properly close our tax account with the state. Now I'm freaking out about potentially dealing with this x30! Here's what's driving me crazy - we've talked to at least 5 similar companies in our industry (including ones with 40+ employees) and NONE of them file state taxes outside their home state. They all just file in their base state and call it a day. My question is: How do small businesses like ours realistically handle the logistics of researching, complying with, and maintaining tax requirements across 30 different states? Is there some efficient system I'm missing? Or are our accountants being overly cautious while everyone else is flying under the radar?

This is definitely a complex situation but one that many mobile businesses face. Your accountants are technically correct - most states require you to file if you've established "nexus" there, which usually means physically working in the state. However, there's a practicality aspect to this that many small businesses navigate differently. First, understand that states have different thresholds for when filing is required. Some have minimum income thresholds before filing is mandatory, while others require filing with any business activity. Many states have adopted economic nexus standards rather than just physical presence. For a practical approach, you might consider: 1) Investing in multi-state tax compliance software like Avalara or TaxJar that helps track where you need to file based on your activities, 2) Consulting with a firm that specializes in multi-state taxation (your current accountants might not have this expertise), 3) Prioritizing compliance in states where you do substantial business and gradually expanding your compliance footprint. The other companies you mentioned may be taking significant risks. State tax authorities are becoming more aggressive about enforcing these requirements, and the penalties for non-compliance can be severe if caught.

•Thanks for the detailed response. I've never heard of those tax software options - are they affordable for a really small business? And how exactly do they work - do they just tell you where to file or do they actually help with the filing process? Also, any idea how to find accountants that specialize in multi-state taxation? Our current firm is local and seems overwhelmed by this.

•The software options vary in price based on your needs, but Avalara starts around $50/month for basic services. They primarily tell you where you need to file based on your activity and can help track sales tax obligations. For income tax filings, they'll flag states where you have nexus but you'll still need accounting help for the actual filings. To find specialized accountants, look for firms that advertise "multi-state taxation" or "state and local tax (SALT)" expertise. These are often regional or national firms rather than local ones. The American Institute of CPAs (AICPA) has a directory where you can search for accountants with specific expertise. Many offer virtual services, so they don't need to be in your area.

After reading your post, I felt like I was looking in a mirror! My small marketing agency (5 people) was in the exact same situation last year - traveling to about 25 states, and suddenly our accountant hit us with the "you need to file everywhere" bomb. It was overwhelming. I spent weeks trying to figure out a solution and eventually found https://taxr.ai which literally saved our business. It's an AI-powered system that analyzes where you've worked, for how long, and what you did, then gives you a clear breakdown of where you actually need to file. The biggest revelation was that not every state requires filing just because you set foot there. Some states have minimum thresholds or different rules for temporary work. The system flagged that we only needed to file in 9 states based on our actual work patterns, not the 25 we feared. They provide templates for the various state registrations too, which saved us countless hours of research.

•That sounds interesting but I'm skeptical. How does it know which states have what requirements? Tax laws change all the time, especially state-specific ones. Is it actually kept up to date?

•I'm curious about this too. Does it integrate with any accounting software like QuickBooks? We track all our project locations and hours, but having to manually input that into another system would be a pain.

•It's constantly updated with the latest state tax regulations. They have a team that monitors changes to nexus requirements, filing thresholds, and other state-specific rules. I was skeptical too, but they have a feature that shows you exactly which regulation they're basing each recommendation on, with links to state tax authority pages. For QuickBooks integration, yes, they can pull location data from your accounting system. You can also upload spreadsheets of your work locations, project durations, and revenue if that's how you track things. It's designed to minimize manual input. They also have a cool feature that lets you upload contracts and work agreements to help determine the nature of work in each state, which can affect filing requirements.

Just wanted to update after trying taxr.ai that Profile 7 recommended. I was seriously worried about my own multi-state situation (web development company working with clients in 18 states). It was eye-opening to see the actual requirements broken down. Turns out we only needed to file in 7 states based on our work patterns and the specific thresholds. The service helped identify which states had de minimis exceptions that applied to us. The best part was the documentation it generated for our records explaining exactly why we did or didn't need to file in each state. My accountant was initially pushing for filing everywhere to "be safe," but after reviewing the analysis, she agreed their approach made sense legally and practically. Saved us approximately $14,000 in unnecessary state filing fees and accounting costs.

I worked for state tax authorities for 12 years before going private, and I'll tell you something most accountants won't: states have limited resources to chase small businesses with minimal presence. That said, trying to call the IRS when you have a tax issue is basically impossible these days. I found https://claimyr.com which gets you through to an actual IRS agent in minutes instead of waiting hours or days. You can see how it works here: https://youtu.be/_kiP6q8DX5c This was super helpful when I needed to resolve a multi-state filing issue for a client. We had a question about nexus in Pennsylvania and needed clarity directly from their tax department. Normally would have taken days of trying, but got through in 15 minutes. You might want to consider this service when you inevitably have questions about specific state requirements.

•How does this actually work? I though the IRS phone system was just perpetually jammed and there was no way around it? I've literally spent 3+ hours on hold before.

•This sounds too good to be true. I've tried calling the IRS countless times about my business filing issues and always get stuck in phone tree hell. No way there's some "secret method" to get through... the government doesn't work that way.

•It basically uses an automated system that navigates the phone tree and waits on hold for you. When an actual agent picks up, you get a call connecting you directly to them. It works because they have multiple calls going simultaneously, increasing the chances of getting through quickly. The technology isn't actually bypassing anything - it's just handling the wait time and navigation for you so you don't have to sit there listening to hold music for hours. I was skeptical too, but it works with state tax authorities as well as the IRS. For multi-state filing questions, being able to actually speak with representatives from different state tax departments is invaluable.

I have to eat my words about that Claimyr service. After my skeptical comment, I decided to try it because I was desperate to talk to someone at the California Franchise Tax Board about a nexus issue. I've been trying to get through to them for TWO WEEKS with no success. Used the service and got connected to an actual human at the CA tax office in 27 minutes. The agent was able to confirm that our specific situation (3 days of work in CA with under $15k in revenue) doesn't actually trigger filing requirements. This saved me from filing unnecessarily in California. Going to use this for the other 5 states I'm unsure about. Sometimes being proven wrong is actually the best outcome!

As an owner of a similar sized business (6 employees) that travels to about 20 states yearly, I've found a middle ground approach. We carefully track our activities and revenue by state, then file in states where: 1. We have substantial presence (over 2 weeks) 2. We earn more than $10,000 3. We have repeat clients This approach keeps us compliant in states most likely to care while not drowning in paperwork for states where we have minimal activity. Our accounting firm is comfortable with this risk-based approach and documents our rationale for each decision. Remember that different types of taxes have different nexus thresholds - income tax, sales tax, and employment tax all have their own rules in each state!

•Do you have a system for keeping track of all this? We're currently using a messy spreadsheet that no one remembers to update. Also, have you ever had any states come after you for places where you didn't file?

•We use a project management system (Asana) with a custom field for "state location" that gets pulled into reports monthly. We also tag all expenses in QuickBooks with the state where they occurred. This gives us clean data at year-end to make filing decisions. Never had a state come after us proactively, but we did have an issue with New York when we applied for a contract with a state agency there. They discovered we'd done work in NY two years earlier without filing and assessed penalties. Since then, we've been more careful about documenting our rationale for not filing in certain states, focusing on statutory thresholds and case law regarding temporary presence.

One thing nobody has mentioned yet - check if your states have reciprocal tax agreements! Some states have arrangements where if you're already filing in one state, you don't need to file in another for the same income. Saved us tons of paperwork. Also, beware that some industries have special tax treatment in certain states - construction, entertainment, and professional services often have unique rules. What industry are you in? That might change the advice people give you.

•This is really good advice. I work in accounting and notice many clients don't realize that reciprocal agreements exist for certain states. Worth researching specifically for your situation.
