Frequently Asked Questions (FAQs)

Q1: Is this calculator accurate for final tax filing?

A: No. This tool provides a quick **estimate only** for planning purposes. Capital Gains Tax calculations are highly complex, depending on your total income, state taxes (in the US), and specific allowances (in the UK). Always consult a qualified tax professional for final filing.

Q2: What is the benefit of holding an asset Long-Term?

A: In the **US**, holding an asset for **more than one year** qualifies it for the preferential Long-Term Capital Gains tax rate (0%, 15%, or 20%), which is significantly lower than the Short-Term (Ordinary Income) rate (up to 37%).

Q3: Does the UK estimate include the Annual Exempt Amount (AEA)?

A: No. To keep the tool simple and fast, our UK estimate uses an average higher rate and **does not deduct** the Annual Exempt Amount or any other personal allowances. You must factor those deductions in yourself.

Q4: Why are Canadian Capital Gains estimates generally lower?

A: In Canada (CA), only 50% of the capital gain is included in your taxable income. The tax is then applied to that 50% portion, making the effective rate much lower than in the US or UK.

Q5: Can I use this for Cryptocurrency or Real Estate?

A: Yes, you can use it for both. Cryptocurrency and Real Estate gains are considered Capital Gains in most jurisdictions (US/UK/CA). Just use the Purchase Price and Selling Price of the asset.


What is Capital Gains Tax? (For SEO)

Capital Gains Tax (CGT) is a tax on the profit when you sell (or 'dispose of') an asset that has increased in value. It's often applied to real estate, stocks, bonds, and cryptocurrencies. Using a calculator helps you estimate your liability quickly and accurately.

In the US, the rate depends heavily on whether the asset was held for less than one year (short-term) or more than one year (long-term). Short-term gains are taxed at ordinary income tax rates, while long-term gains benefit from preferential, lower rates.
