California tips from Donald Trump’s move from New York to Florida

Long before he became president, Donald Trump was known as an aggressive taxpayer who pushed the envelope. In that sense, his latest tax move -- from New York to no-tax Florida -- practically seems anticlimactic. Of course, he announced the move by tweet, saying that New York City "will always have a special place in my heart!" He added that he had paid "millions of dollars in city, state and local taxes each year," but claims he was "treated very badly by the political leaders of both the city and state."

Since his announcement, there has been considerable commentary about the move and what kind of audit he might face. Many sources are rightly wondering if the president's departure from New York for tax purposes could be examined. After all, tax disputes about state residency are very common, and in this case, it seems even more likely that the president will face an audit from his long-time home state of New York.

For anyone trying their own version of President Trump's tax move, consider these points. New York and California are both notorious for fighting over residency, and neither state takes losing wealthy taxpayers lying down. With the high rates in New York and California, it is no wonder that these disputes matter. Arguably, though, the situation for Californians is the toughest of all.

Indeed, even if you leave the state, depending on the type of income you have, California can assess taxes no matter where you live. Californians complain about high taxes even more than New Yorkers do, and some Californians vote with their feet, moving to no-state income tax states like Nevada, Texas, Washington or Florida. Reports say many millionaires fled California after the last tax increase, with studies noting that some of the highest earners left.

California's Proposition 55 extended until 2030 the "temporary" 13.3% tax rate on California's highest incomes. You pay the same rates on capital gain as ordinary income, which can make big capital gains painful. It is worth calculating the savings you expect for the first year, and/or annually. Remember, federal tax law now limits state and local tax deductions to $10,000. Paying high California taxes could always have been a motivation to move.

Yet today, if you are paying huge tax dollars to California and can deduct only $10,000 on your federal taxes, it is likely to smart that much more. The IRS reported that between 2013 and 2014, over 250,000 California residents moved away between 2013 and 2014. More than 10% went to Texas alone, and with 2018 tax changes, more may follow. But California's tough Franchise Tax Board monitors the line between residents and non-residents, and does so rigorously.

As with other high tax states, California is likely to probe how and when you stopped being a resident. For that reason, even if you think your facts are not controversial, be careful. A California resident is anyone in the state for other than a temporary or transitory purpose. It also includes anyone domiciled in California who is outside the state for a temporary or transitory purpose.

The burden is on you to show that you are not a Californian, which can be tough. Year after year, no state has a bigger cadre of would-be tax fugitives than California. Some Californians look to flee the state before selling real estate or a business. Some get the travel itch right before cashing in shares, a public offering, or settling litigation. If you are hoping to collect on a post-move sale of your company, settling a big lawsuit, or have some other upcoming large income event, don't cut it too close.

Move with plenty of time if possible. Many would-be former Californians have unrealistic expectations about establishing residency in a new state. They may have a hard time distancing themselves from California, and they may not plan on California tax authorities pursuing them. When fighting California tax bills, procedure counts, so pay close attention to each notice and request.

You can have only one domicile, and it depends on your intent. However, objective facts can and do bear on it. To determine your domicile, start with where you own a home. Where your spouse and children reside counts too, as does the location where your children attend school. Your days inside and outside the state are important, as is the purpose of your travels.

Where you have bank accounts and belong to social, religious, professional and other organizations is also relevant. Voter registration, vehicle registration and driver's licenses count. Where you are employed is key. You may be a California resident even if you travel extensively and are rarely in the state. Where you own or operate businesses is relevant, as is the relative income and time you devote to them. Taxpayers with unrealistic expectations can end up with big bills for taxes, interest and penalties.

Once you move, cut as many ties as you can, and be very careful. If you are in California for more than 9 months, you are presumed to be a resident. Yet if your job requires you to be outside California, it usually takes 18 months to be presumed to no longer be a resident. You can only have one domicile, which is defined as your true, fixed permanent home, the place where you intend to return even when you're gone.

Many innocent facts might not look to be innocent to California's tax agency. For example, do you maintain a California house or apartment in a state of constant readiness for your return? Think about audit times too. Although the IRS can audit your returns for three or six years, California can sometimes audit forever. In fact, several things give the FTB an unlimited amount of time to audit you.

California, like the IRS, gets unlimited time if you never file an income tax return. You might claim that you are no longer a resident and have no California filing obligation. The FTB may disagree. That can make filing a non-resident tax return -- just reporting your California-source income as a non-resident -- a smart move under the right facts.

To return to the President, even if New York ends up agreeing with him that he will no longer be a New York resident, he will surely be paying New York taxes on his New York source income. That could well be considerable, depending on what those elusive tax returns show, so don't forget about California source income either. A move won't help shield California taxes on that. 
