Part of the StockEducation tool library built for clearer investor learning.
In the United States, tax on a share sale depends partly on how long you held the asset. A holding period of one year or less creates a short term gain taxed at ordinary income rates. A period of more than one year can qualify for long term rates of 0%, 15% or 20%, depending on taxable income. The 3.8% net investment income tax and state tax may also apply. The free Capital Gains Tax Helper explains the rules and works through your example. Tax thresholds change each year, so check current IRS guidance or ask a tax professional.

This output is generated by AI from OpenAI and Perplexity. It is good at structuring information and explaining what a figure means. It can be wrong about facts, out of date, or confidently invent things that are not true.
It knows nothing about your finances, goals or tax position. Everyone who enters the same information gets the same output.

Disclaimer · Terms of Use
No. This is not tax advice.
Tax rules depend on your country, your state, your income, your holding period and your personal circumstances. They also change.
This tool applies simplified general rules and knows none of that about you. The number it produces may be wrong for your situation.
Do not file, report or plan around this figure. Confirm it with a licensed tax professional or directly with the IRS before you act.
Educational content only. This tool does not provide legal, tax, financial or investment advice. Tax rules can change and depend on personal circumstances. Always verify with official sources or a licensed tax professional before acting.
The Capital Gains Tax Helper is a free educational Q&A tool that explains how capital gains may be taxed in the US, Australia, UK, Canada and Hong Kong in plain English. Include the country code in your question for a more useful answer.
Add US, AU, UK, CA or HK to your question. Tax rules vary materially; country code lets the AI give a jurisdiction specific answer instead of a generic one.
“How does the AU 12 month discount work?” is much better than “How does CGT work?” Specific questions get specific answers.
Educational only. Tax rules change frequently and apply differently to individuals based on residency, income, asset type and timing. A registered tax agent is essential before acting.

Why use it
Specific educational outcomes for investors learning tax basics.
US, AU, UK, CA, HK CGT rules explained in plain English. Useful for investors holding cross border assets.
Tax terminology (cost base, indexation, holding period) translated into everyday language.
The tool tells you when to stop and call a tax agent. Tax answers depend on circumstances no AI can know.
Below is a sample explanation the AI returns for a typical AU question. Exact rules change; always confirm with a registered tax agent.
Answer drawn from ATO published rules on the CGT discount. The 50% individual rate is the standard discount; companies and trusts have different treatment. The 12 month holding period is measured from contract date to contract date. High confidence because this is well established ATO guidance, but specific application depends on individual circumstances.
Caveats are critical because the discount has multiple eligibility conditions. Loss application order matters for the final tax outcome. Entity type changes the rate. Foreign residency rules are different. These exclusions matter for many real situations. High confidence because each is an ATO published rule.
Personal tax outcomes depend on factors AI cannot know (full income picture, losses, entity structure, residency history). The AI deliberately flags Limited confidence and points to a registered tax agent. This is the safest YMYL pattern for tax questions.
What you see in the raw input vs what the AI surfaces from it.
AI output is a starting point, not a conclusion. Use this 3 step check before acting on anything the AI says:
Your input text is sent to the AI model provider (OpenAI via API) for processing. Your input is sent to the AI provider for processing and is not stored on our servers. The AI provider may briefly process input under their published data policy. See the OpenAI data policy[1].
Capital gains tax (CGT) varies dramatically across countries. Hong Kong charges 0% on most personal investment gains. Australia gives individuals a 50% discount on gains held more than 12 months. The US distinguishes long term vs short term at the 1 year mark. The UK has an annual exempt amount. Canada uses an inclusion rate.
This tool explains how each jurisdiction works in plain English. Useful for investors learning the basics, comparing across jurisdictions, or preparing for a tax agent conversation. It is not a substitute for personal advice; tax outcomes depend on factors AI cannot know.
We use the base GPT model with a custom system prompt tuned for jurisdiction specific tax education. The prompt explicitly directs the AI to flag personal advice limits and recommend registered tax agents for any meaningful CGT event. Knowledge cutoff is recent; tax rules change frequently, always verify against the current tax authority website.
Use AI answers as a research starting point and a glossary of terms. The “plain English explanation” is most reliable.
Always check the AI flagged caveats and the “confirm with a tax agent” recommendation. These flag the limits of AI tax answers.
The biggest factor in AI output quality is the input. Three side by side examples.
AI explains general tax rules. Personal tax decisions require a registered tax agent.
Yes. Free to use, no signup required.
GPT via the OpenAI API with a custom prompt tuned for tax education with strong adviser handoff. Knowledge cutoff is recent.
No. Tax outcomes depend on factors AI cannot know. Always confirm with a registered tax agent before acting.
US, Australia, UK, Canada and Hong Kong primarily. It can attempt other jurisdictions but quality is best for these five.
Knowledge cutoff is recent. Tax rules change every year in most jurisdictions. Always verify against the current tax authority website.
No input or output is logged or stored on our servers. Critically, do not include any personally identifying details, TFN, SSN, account numbers, or specific dollar amounts.
Add US, AU, UK, CA or HK to your question. “AU: how does the 12 month discount work?” is much better than “How does the discount work?”
Yes for general rules in covered jurisdictions. Crypto CGT rules change frequently; always verify against the current tax authority guidance.
The AI used in this tool is GPT via the OpenAI API. Editorial team maintains the prompt and reviews quarterly. Tax rule references draw from official tax authority publications.
This AI tool is provided for general educational purposes only. It does NOT constitute tax, legal or financial product advice. Tax outcomes depend on individual circumstances including residency, income, asset type, entity structure and timing. Tax rules change frequently. Always confirm with a registered tax agent or accountant before acting on any tax matter. The tool deliberately recommends professional advice for any meaningful CGT event.
