Foreigners can generally stay in the U.S. for fewer than 183 days in a calendar year without automatically becoming a tax resident under the Substantial Presence Test (SPT). To avoid taxation, they must stay under 31 days in the current year, or meet a specific three-year formula that includes 1/3 of days from the previous year and 1/6 from the year before.
How Many Days Can You Be in the U.S. Without Paying Taxes? The IRS considers you a U.S. resident if you were physically present in the U.S. on at least 31 days of the current year and 183 days during a three-year period.
The specific details of the rule can vary from one location to another, but the core concept is that if an individual stays within a particular area for at least six months and one day (or 183 days) during a tax year, they may be deemed a tax resident of that area and subject to its tax laws.
This commonly referenced rule is part of many international income tax treaties and generally states that an individual may be exempt from income tax in a Host country if they are present in that country for fewer than 183 days within a defined period – often a calendar year or rolling 12-month period.
The IRS $600 rule refers to a change in reporting requirements for third-party payment apps (like Venmo, PayPal) for taxable income from goods and services, where platforms must send a Form 1099-K if you receive over $600 in a year, intended to capture gig economy/side hustle income, though delays and phased implementation have adjusted the timeline, with current rules for 2024 using a higher threshold ($5,000) before fully phasing to $600 for future years, but remember all taxable income, regardless of form, must always be reported.
The IRS "10k rule" primarily refers to the requirement for businesses and financial institutions to report cash transactions over $10,000 by filing Form 8300 (for businesses) or a Currency Transaction Report (CTR) (for banks), under the Bank Secrecy Act.

Canadians and other foreign nationals visiting the United States for periods longer than 30 days must be registered with the United States Government.
The "90-day rule" for non-residents typically refers to two different concepts: in U.S. immigration, it's a guideline for determining if a non-immigrant misrepresented their intent by engaging in certain activities (like unauthorized work or immediate marriage) within 90 days of arrival, leading to visa fraud or inadmissibility. In Canadian tax law, the 90% rule allows non-residents to claim full federal tax credits if 90% or more of their world income is from Canadian sources, otherwise, credits are prorated.
The IRS 7-year rule primarily applies to keeping records for claiming a deduction for bad debts or losses from worthless securities, allowing a longer period to file for a credit or refund, but it's not a universal audit limit; it's often a recommended safe buffer for general record-keeping, with the standard IRS audit period usually being 3 years, extending to 6 years for substantial income omission (over 25%) or foreign income issues, and indefinitely for fraud.

Many states that collect income taxes use the 183-day rule to decide who is considered a resident of their state. According to the rule, if you spend at least 183 days of a year in a state — even if you have established your domicile in another state — you are considered a resident of the state for tax purposes.
On a $100,000 capital gain, you'll likely pay 15% for long-term gains, resulting in about $15,000 in federal tax (plus potential state tax), but it could be 0% or 20% depending on your total taxable income and filing status, while short-term gains are taxed as ordinary income (potentially 22-24%).
Also, if you intend to stay longer than 90 days, then you need to apply for a visa.
A nonresident alien (for tax purposes) must pay taxes on any income earned in the U.S. to the Internal Revenue Service, unless the person can claim a tax treaty benefit. This applies to students as well.
Generally, you do not need to tell HMRC if you are leaving the UK for a short period, such as for a holiday or brief business trip. However, if you are leaving the UK to live overseas, at the very least you should advise HMRC of your new residential address (and correspondence address, if different).

If you're in Canada for less than 183 days and don't have significant ties to the country—like a home or family here—you could be considered a non-resident. Non-residents are generally only taxed on income earned in Canada, not on worldwide income.
The INA requires that, with limited exceptions, all aliens 14 years of age or older who were not registered and fingerprinted (if required) when applying for a U.S. visa and who remain in the United States for 30 days or longer, must apply for registration and fingerprinting.
How severely you are punished depends on how long you overstayed a visa: 180 days to one year: You will not be allowed to enter the United States again for three years. One year or more: You will not be able to obtain a visa for 10 years. You could also face fines and jail time for ignoring a final order of removal.
If you spend 183 days or more maintaining a place of residency in a location during the tax year, you are considered a resident for tax purposes in areas like Washington D.C. The IRS uses a formula that considers your presence in the current year, along with a fraction of your presence in the two prior years.
Depositing $2,000 in cash isn't inherently suspicious and is well below the $10,000 reporting threshold for banks, but it can raise flags if it's part of a pattern (structuring), inconsistent with your normal income, or involves other red flags like frequent large cash deposits from others, leading to a potential Suspicious Activity Report (SAR). To avoid issues, have clear records for the cash's source, like invoices or sales receipts, especially if you deal in cash often.
