Throughout the 20+ years of my tax career I have seen one issue roar it’s ugly head over and over again for both individuals and companies alike- using an out of state address on a tax return. This innocent-seeming mistake can end up costing you thousands of dollars in taxes, penalties, interest, and representation fees. 

Why are addresses so important on tax returns?

Many states will use federal tax return addresses as a database to search for people and businesses in their state who are not filing and paying state tax returns. This can lead to trouble if you do not file state tax returns properly.

For example, if you use a California address on your tax return and fail to file a California tax return, then it is highly likely that California will come knocking asking you why. For businesses especially, as California has an $800 minimum tax that they enforce strictly, you will most likely receive a bill in the mail for that $800 tax plus penalties if you don’t file in California. 

Now if a business is actually operating in California, say you live there and are running the business out of your garage, then you will need to register with the Franchise Tax Board and file a California tax return and pay tax. But if you live in the UK and have a US business and want to use a California address just to look like you’re operating from Silicon Valley, this is where the trouble comes in. Under California law just putting it out to the public that you are operating in California, i.e. by putting that address on your website, then you also are making yourself subject to having to pay tax in California. I have seen this bite many startups in acquisition deals over the years where hundreds of thousands of dollars are held back from the sale for possible state tax liabilities, just because of a California address used for a couple years. 

Which other states are risky to use addresses in?

While aggressive tax enforcement states like New York, New Jersey, and Massachusetts may come to mind if you know a good bit about US taxes, there are other ones that may not be so obvious at first glance. Oregon, Colorado and Florida are other states that, from experience, I have seen go after taxpayers very aggressively. You may be surprised to see Florida on that list and ask, “isn’t that a tax-free state?” While Florida does not have an individual income tax, they do have a corporate income tax, and they enforce that rather aggressively. 

What state addresses are better to use for tax purposes?

The obvious answer is to use an address in the state you are operating in. Usually this means registering your company as a foreign business if you formed it in another popular formation state like Delaware or Wyoming. But if you live in a state and are operating the company from there, the likelihood is high that you will meet the state “nexus” rules, meaning that they have the right to tax you. 

If you don’t operate from the US at all, then you should choose an address either in the state you incorporated in or a tax-free state like Wyoming or Nevada. Another good choice can also be Texas, especially for companies that want to give that tech-forward look. In Texas there is no income tax, but there is a franchise tax based on business assets. 

Can’t I just use my registered agent’s address?

While some registered agents will offer a mail service, many will either charge very high rates for this service or just turn away mail altogether. We also have found certain addresses will be rejected for some tax filings. For example, most Delaware registered agents addresses can no longer be used for Delaware Franchise Tax filings and will be rejected when they are used. And if your Delaware Franchise Tax Report gets rejected there are high penalties and interest that can result. Filing a federal tax return with a registered agent address can also be risky, as often tax notices are seemingly lost or not delivered, or that has been many of my clients’ experiences. 

Registered agent addresses also can be risky for banking and operational purposes, as many of them show up under fraud searches as the addresses that fraudsters have used in the past. This could possibly lose you an important client in the future or get your bank shut down if you are operating abroad and aren’t showing a substantial US presence. 

Case Study: Navigating California Nexus Laws and Protecting Future Acquisition Opportunities

Client: Media & Sound Company  

Industry: Sound & Media  

Challenge: Addressing California Nexus laws and safeguarding against tax penalties

Background:

A media and sound company filed its 2022 California tax return using a California address without marking the return as final. Though the company no longer had operations in the state, it still used the address, potentially triggering ongoing tax liabilities under California’s nexus laws. In California, even a mailing address can establish nexus, creating tax obligations for the company, even without a physical presence.

Problem:

Filing with a California address indicated to the California Franchise Tax Board (FTB) that future tax returns would be expected. If the company failed to continue filing, the FTB could assess taxes and penalties based on an assumed ongoing presence in the state.

This posed a serious risk, especially since the company was considering a future acquisition. Unresolved tax liabilities could become a red flag during due diligence, with buyers potentially holding back large sums to cover these risks. Even without acquisition plans, the company faced California’s $800 minimum tax and the possibility of back taxes if future filings were not completed.

 Recommendations:

1. Change Address to Avoid California Nexus  

We recommended the company update its mailing address to a state without income tax, such as Wyoming, or to Delaware, where the company was registered, to avoid ongoing nexus in California. This would allow the business to avoid filing future California tax returns.

For those wanting to maintain a prestigious address, we suggested using Austin, TX, which offers a tech-friendly environment similar to Silicon Valley but without the heavy tax burden. A mail service in Texas was offered as a solution to facilitate this change.

2. Filing a Final California Return  

We outlined two options to resolve the company’s California tax situation:

   – File a Final 2023 California Return: The company could pay California’s $800 minimum tax for 2023 and mark this as the final return. This would ensure no further obligations in the state and was the safest route for businesses considering future acquisition. Having a clean tax record would avoid potential tax risks being flagged during buyer due diligence.

   – Amend the 2022 California Return: If an acquisition wasn’t likely, amending the 2022 return to mark it final for $199 was an option. Future returns could then be filed using the Delaware address, removing California’s nexus and tax filing requirements.

Outcome:

After careful consideration, the company decided to file its 2023 tax returns, including a final California return, and pay the $800 minimum tax. This approach allowed the company to formally close its obligations in California while ensuring it maintained a clean and compliant tax record. The decision to file the 2023 return and mark it as final was made with potential future acquisition in mind, safeguarding against any tax risks that could arise during due diligence.

By opting for this approach, the company minimized its exposure to California’s aggressive tax collection practices and positioned itself favorably for any future acquisition opportunities. Filing the 2023 California return eliminated the potential of having large amounts withheld in a sale due to unresolved tax issues, providing peace of mind and a clear path forward.
