Most people start thinking about U.S. taxes after they arrive. By then, the most valuable planning opportunities are already gone.

Most people give to charity the same way every year: a check, a credit card, an online donation in December. If you also own stock, real estate, crypto, or a business that has grown substantially in value, that habit is likely costing you money. The most tax-efficient gift you can make is usually not cash. It is the asset you would otherwise have to sell and pay capital gains tax on.

A dollar received on December 31 and a dollar received on January 1 are taxed in different years. That one-day difference can change your tax bracket, your capital gains rate, and even which credits you qualify for.

An IRS penalty notice feels final. It is not. Failure-to-file and failure-to-pay penalties are among the most frequently reduced or removed charges in the entire tax system, but only for taxpayers who ask the right way, for the right penalty, at the right time.

You set up a one-person company in Hong Kong, the U.K., or Taiwan to run your consulting work or hold a property. Someone told you it is "disregarded" for U.S. tax purposes, so the income just flows onto your return. That part may be true. What is often missed is that a disregarded foreign entity comes with its own information return, Form 8858, and a $10,000 penalty for each year it is not filed.

You worked abroad, paid tax to a foreign country, and claimed the federal foreign tax credit. Your federal tax on that income dropped to zero. Then your state return arrived with a bill.

If your company is the U.S. arm of an overseas group — a sales or distribution subsidiary of a manufacturer in Taiwan, Japan, Korea, or China — your tax preparer almost certainly files Form 5472 to report transactions with your foreign parent. The question fewer people ask: should your company also have been filing Form 5471 for its foreign sister companies?

Congratulations — the green card is approved. Your immigration attorney has handled the visa. But if you own a company overseas, there is a second deadline most new residents never hear about: the day you become a U.S. tax resident, your foreign company becomes part of your U.S. tax picture.

Most taxpayers think about audits only after an envelope from the IRS shows up. By then, the outcome is already largely decided — not by what you say to the examiner, but by what records you kept two or three years ago. An audit is not an accusation. It is a request to prove what you reported. Taxpayers who lose audits usually did not cheat; they simply cannot substantiate a deduction they were entitled to, or they cannot explain a bank deposit that was never income in the fi

Here is the good news first: if your parents overseas send you money, or a relative abroad leaves you an inheritance, you generally do not owe U.S. income tax on it. A gift is a gift.

“I moved back home, so I’m done with the U.S.” It is one of the costliest assumptions a green card holder can make. Leaving the country, letting the card expire, or shelving it in a drawer does not end your U.S. tax residency. Only a formal event does. Until then, the IRS still expects a return on your worldwide income, and sometimes years of back filings.

Most people think a charitable deduction comes from writing the check. To the IRS, it comes from the paperwork. A gift can be completely genuine and still be denied if you can’t prove it. With Giving Tuesday on December 1 and year-end about three months away, now is the time to set up your records, not next April. Step 1: Confirm the Charity Qualifies • Only gifts to qualified organizations are deductible. Check any charity you’re unsure about using the IRS Tax Exempt Org

A losing year in your business isn't just bad news to survive — it's a tax attribute to manage. Between basis limits, at-risk rules, passive activity restrictions, the excess business loss cap, and the net operating loss (NOL) rules that pick up whatever's left, a single loss can pass through four or five separate gauntlets before it actually reduces your tax bill. And thanks to the One Big Beautiful Bill Act (OBBBA), signed into law in July 2025, one of those gauntlets just

Selling a stock, a rental property, a piece of equipment, or shares in a small business? The sale itself is often the easy part — it's the reporting afterward that trips people up. Small errors on your tax return can lead to IRS notices, overpaid tax, or penalties that were entirely avoidable. Here are the most common asset sale reporting mistakes we see, and how to steer clear of them.

A net operating loss (NOL) lets you carry a loss year forward to lower a future tax bill. The basic rule is the same for every taxpayer, but if you have foreign income, the loss can interact with your return a little differently. Here's the simple version.

Meeting a residency test in two countries is one problem. Having both countries actually assess tax on you as a resident, in the same year, is a different and more urgent one. When that happens, you're no longer just planning around the rules — you're in an active dispute, and the clock on how you respond matters as much as the facts themselves.

If you split your time between the U.S. and another country — or moved abroad but kept ties back home — you may meet the legal test for tax residency in both places at once. Dual residency is not automatically a problem, but it is a warning sign that your U.S. filing could be wrong if it is not addressed, and it can lead to the same income being reported as taxable in two countries with no relief unless you claim it correctly.

Internal structure in CFCs If you're a U.S. person who owns (or has a stake in) a company incorporated outside the United States, three terms should be on your radar: Controlled Foreign Corporation (CFC), Subpart F income, and GILTI. These rules exist to prevent U.S. shareholders from parking profits offshore indefinitely — and they can generate a current U.S. tax bill even if you never see a dividend from the foreign company. This week, we're breaking down how these three pi

A rental is a rental, right? Not when it's overseas. Foreign rental real estate is stuck on a slower depreciation schedule with no bonus depreciation, and recapture at sale brings in currency translation and FTC sourcing that most software won't catch. Here's the full domestic-vs-foreign comparison.

Foreign Stock Plans and RSUs If you work for a multinational employer and your compensation package includes Restricted Stock Units (RSUs) or participation in a foreign stock plan, you're sitting on more than an investment — you're sitting on a reporting obligation that most people don't discover until it's too late. Whether you're a U.S. person working abroad, a foreign national working in the U.S., or someone who's relocated mid-vesting-schedule, equity compensation adds a
