The IRS determines a home's fair market value (FMV) as the price it would sell for on the open market between a willing buyer and seller, neither being under compulsion to act. It primarily relies on comparable sales (comps), professional appraisals, and physical inspections to establish value, particularly for estate or gift tax purposes.
To prove the IRS's 2-out-of-5-year rule, you must show you owned and lived in your home as your primary residence for at least 24 months (two years) (not necessarily consecutive) within the five years before the sale, using documentation like utility bills, driver's license, voter registration, tax returns, bank statements, and mail all showing the home address. This proves you meet both the ownership and use tests for excluding capital gains on the sale, requiring documentation to back up your claim of residency during that period.
The fair market value of a residential property can be calculated by comparing the recent sale prices of similar homes in the neighborhood. Utilizing the services of a professional home appraiser is the most accurate way of calculating the fair market value of a home.
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. This rule helps combat money laundering, tax evasion, and terrorist financing, requiring reporting for single transactions or related transactions totaling over $10,000 in cash within a year, with penalties for non-compliance.
The bottom line is that the IRS expects you to maintain records that identify the cost basis of your securities. If you don't have adequate records, you might have to rely on the cost basis that your brokerage firm reports—or you may be required to treat the cost basis as zero, which could mean owing more in taxes.
A Zestimate is created using an algorithm based on public records. While it can be reasonably accurate for properties currently on the market, it is often off by tens or even hundreds of thousands of dollars. Your best bet is to work with a licensed realtor for the most accurate estimate of a property's value.
The "3-3-3 rule" in real estate isn't a single guideline but refers to different strategies: for buyers, it's about financial readiness (3 months savings, 3 months reserves, 3 property comparisons) or a financial affordability check (30% income, 30% down, 3x income); for agents, it's a marketing habit (call 3, note 3, share 3) or prospecting (talking to everyone within 3 feet). There's also a developer rule (1/3 land, 1/3 build, 1/3 profit), though it's considered outdated by some.
Fair market value is the standard by which the fairness of all assessments is judged. Buyers and sellers determine the fair market value of real estate. The appraiser or assessor analyzes real estate transactions that occur within a community and determines the factors that led to the final sale prices.
The primary purpose of the 75% Rule is to ensure that the Replacement Property aligns closely with what was initially identified. This alignment is crucial for maintaining compliance with the IRS regulations and securing the tax-deferral benefits of a 1031 exchange.
The 7 year rule
No tax is due on any gifts you give if you live for 7 years after giving them - unless the gift is part of a trust. This is known as the 7 year rule.
Determine whether you meet the residence requirement.
If you owned the home and used it as your residence for at least 24 months of the previous 5 years, you meet the residence requirement.
Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
The IRS does not check every tax return. It does not check the majority of them, but the IRS implements methods that track certain factors that would result in a further examination or audit by them.
Who Is Audited More Often? Oddly, people who make less than $25,000 have a higher audit rate. This higher rate is because many of these taxpayers claim the earned income tax credit, and the IRS conducts many audits to ensure that the credit isn't being claimed fraudulently.
When someone inherits investment assets, the IRS resets the asset's original cost basis to its value at the date of the inheritance. The heir then pays capital gains taxes on that basis. The result is a loophole in tax law that reduces or even eliminates capital gains tax on the sale of these inherited assets.
The 20% rule for capital gains refers to the highest federal tax rate for long-term capital gains, applying to higher income brackets when you sell investments (stocks, real estate) held for over a year, with lower rates of 0% and 15% for lower incomes, and even higher rates for special assets like collectibles. This rate kicks in for single filers earning over approximately $492,300 (2024) or $533,401 (2025), and higher for joint filers, making holding assets over a year a key tax strategy.
The IRS requires us to track the cost basis, holding period, and certain other tax information for most securities and report this information for the tax year in which they are sold.
You generally need to file a U.S. federal tax return if your gross income for Tax Year 2025 (filed in 2026) is above a certain threshold, which varies by filing status and age, for instance, $15,750 for single filers under 65, while self-employed individuals must file if they earn $400 or more in net earnings. Thresholds increase for married couples and those 65 or older, but you might still need to file to claim a refund or refundable credits even if below the income limit.
