Investing feels modern... until the annual close comes and these questions come up: “Does the sale of shares pay SII taxes?”, “Do dividends pay taxes in Chile?”, “if I trade, how do I declare?”. And when you add foreign brokers, funds, bonds, time deposits or even derivatives, confusion is almost guaranteed.

In this guide I explain, in simple terms, How does stock sales tax work in Chile, what changes if you are a natural person or company, what happens with actions abroad, how do you order the Trading, and which instruments usually have special obligations (funds, bonds, DAP, stock market transactions and derivatives).

Spoiler: many times the problem is not “to pay or not to pay”, but Calculate well and Back up.

Executive Summary (TL; DR)

  • The sale of shares can pay taxes in Chile, but it depends on technical variables: type of instrument, form of acquisition, market where it is traded, customary status, and your tax situation (person/company; Chile/abroad).
  • The tax is normally triggered by the Higher value (profit): sale — tax cost — associated expenses.
  • Dividends pay taxes in Chile directly or indirectly (with credits/integration as appropriate), and if they come from abroad, they must be treated with care.
  • If you invest outside, in addition to income, there is usually reporting obligations (for example, affidavits related to transactions/investments abroad).
  • Trading = more transactions, more points of failure: costing, commissions, exchange rate, reconciliation and classification.
  • Investments that don't pay taxes in Chile” exists only in specific scenarios or because of conditional exemptions; often the correct thing is to say: “does not pay today, but it may still require declaration and support”.

1) Tax on the sale of shares in Chile

To know if we should pay taxes, what we really need to ask ourselves is:

  1. Is my gain affected or exempt?
  2. How do you calculate the highest value?
  3. Where and how is it declared?

The short answer: may be affected or may be exempt, and the difference is usually in the detail (and in the documentary evidence).

1.1 Sale of natural person vs company shares: it's not the same thing

Sale of natural person shares:

  • Generally speaking, if you get a Higher value, that result may be affected by final taxes (depending on your situation and the type of transaction).
  • The key is usually in: origin of the instrument, form of transaction and special rules for certain cases.

Sale of shares by a company:

  • Normally the company recognizes results in its tax base and the final effects depend on the regime.
  • In addition, a company usually requires full accounting, reconcilations and more robust support.

The important thing: don't start from “exempt/affection”. Departs from Classify the operation correctly.

1.2 Tax on earnings from the sale of shares: how it is calculated (without losing you)

The phrase”tax on earnings from the sale of shares” is synonymous with this:

Higher value (profit) = Sales Price — Tax Cost — Associated Expenses

Where “associated expenses” usually include:

  • broker/broker fees,
  • transaction costs,
  • spreads/fees,
  • and, in foreign investments, the exchange rate can be decisive.

The Big Mistake is to calculate it “by eye” with a partial Excel or only with the Performance report of the broker. For taxes, you need a traceable tax costing.

1.3 What documents do you need yes or yes?

In order for your calculation to “withstand auditing”, you should usually have:

  • Postcards and confirmations (purchase/sale).
  • Details of commissions and fees.
  • Record of corporate events (splits, merges, rights, reinvested dividends).
  • Exchange rate used (consistent and justifiable).
  • Annual reconciliation: What your broker says vs what you declare.

2) “The sale of shares pays SII taxes”: what the SII really looks at

The keyword “the sale of shares pays SII taxes” reflects real anxiety: “Will the SII be observed if I sold and didn't declare properly?”

In practice, IBS usually looks at three things:

2.1 Coherence between movements and declared income

If you had sales, dividends, redemptions or significant movements, Expect consistency with:

  • your annual return,
  • your certificates (when they exist),
  • and the economic logic of your numbers.

2.2 Cost traceability

A “gain” or a “loss” without cost support is a red flag.
Your calculation should explain:

  • When did you buy,
  • At what price,
  • with what commissions,
  • and how you arrived at the result.

2.3 Declaring isn't just paying

You can have scenarios where the final tax is low or even zero, but Are there still informational obligations or registration.

3) Do dividends pay taxes in Chile?

Yes: Do dividends pay taxes in Chile, although the exact form depends on:

  • if they come from a Chilean company or from abroad,
  • your capacity as a taxpayer (natural person/company),
  • and the applicable tax/credit structure.

3.1 Chile's dividends: the classic “they deposited me and that's it”

The deposit is just the end of the process. For tax purposes, the following are important:

  • the certificate,
  • the associated credit (if applicable),
  • and the way in which it is integrated into your annual return.

3.2 Dividends from abroad: when your broker doesn't say “SII”

Here the typical problem is twofold:

  1. Rent: include it correctly (amount, date, exchange rate).
  2. Support: the broker can report in another way (for example, reports by country, by account, by different fiscal year).

If you receive dividends from abroad on a regular basis, you should set up a monthly registration (not just annual) to avoid reassembling everything in March.

4) Foreign stock taxes (IBKR, Pershing and others)

The need to pay taxes for shares abroad is growing every year for a reason: investing abroad is easy today; Tribute well not so much.

There are two layers:

4.1 Layer 1: income (profits, dividends, interest)

Even if your broker is outside, if you have tax obligations in Chile, what is relevant is:

  • higher-value sales,
  • dividends,
  • interests,
  • rescues,
  • and commissions/fees that affect the result.

4.2 Layer 2: reporting obligations (affidavits)

In international investments, many times the cost of “not ordering” is that you end up with:

  • incomplete statements,
  • inconsistencies between years,
  • and rectifiers that turn into a snowball.

Rule of thumb: if you invest abroad, your tax accounting needs to be more like portfolio accounting rather than an “annual summary”.

5) Taxes for trading Chile

“I did a lot of trading, won something, lost something... how do you declare it?”

Trading isn't just “buying and selling”. For taxes, trading means:

  • a lot of transactions,
  • fragmented results,
  • more commissions,
  • plus FX,
  • and a real risk of costing errors.

5.1 How to file trading taxes (step by step)

This is the sensible route:

  1. Consolidate data (all accounts, all brokers, all year round).
  2. Normalize (currency, dates, commissions, instruments).
  3. Calculate results by transaction and by instrument (and its tax logic).
  4. Square against top cards (your P&L has to match reality).
  5. Build the support (papers, reports, endorsements).
  6. Declare in the appropriate way depending on the type of rent/transaction.

Common mistake: use the broker's “realized P&L” as if it were a tax base. It serves as an input, but not always as a final answer.

6) “Investments that don't pay taxes in Chile”: beware of the myth

It's dangerous because it pushes for wrong decisions. In practice, the right thing to do is talk about:

  • Conditional exemptions (you meet requirements, if not, it does not apply).
  • Unrealized events (earnings “on paper” that have not yet been triggered).
  • Withholded/definitive tax (it doesn't “don't pay”; it pays another way).
  • Different tax moments (you don't pay today, you pay the ransom or sale).

6.1 What is often confused with “does not pay”

  • Unrealized price increases: if you don't sell, there is usually no greater realized value (but be careful with instruments that have specific rules).
  • Automatic reinvestments: they don't always mean “no taxation”; it depends on the instrument and the event (contributing/rescue/dividend).

6.2 Exemptions: Exemptions exist, but they are technical

In Chile, there are special regimens and regulations that may leave certain results exempt or with preferred treatment. if strict requirements are met (type of instrument, market, form of transaction, etc.).

Honest message: If your strategy is based on “don't pay”, first validate if your case fits. Otherwise, the strategy becomes a risk.

7) Not just stocks: funds, bonds, time deposits, stock trading and derivatives

Generally, as investors, your portfolio has a mix of these.

7.1 Mutual Funds and Investment Funds

  • Mutual funds: rescues with their own rules (and certificates that often help, but don't solve everything).
  • Investment funds: different logic (and different events).

Key point: the “result” can come from redemptions, distributions and valuations depending on the instrument.

7.2 Bonuses

In bonds, the world is divided into:

  • interests/coupons (periodic income),
  • Result per sale (higher value or loss),
  • and currency/FX effects.

If you hold bonds in international custody, support (statements) is essential.

7.3 Term Deposits (DAP)

The DAP seems simple, but:

  • has interests,
  • it may be in foreign currency,
  • can be automatically renewed,
  • and if you have it in several institutions, annual reconciliation becomes necessary.

7.4 Trading transactions (simultaneous, pacts, etc.)

These operations are usually “the gray area” where:

  • the investor believes it's just “funding”,
  • But in terms of taxation you have to Disarm the operation and document it well.

7.5 Derivatives

Derivatives raise the standard of compliance:

  • more variables (underlying, liquidation, valuation),
  • more reports,
  • and usually more traceability requirements.

If your portfolio has derivatives, don't treat it as an “attachment”: treat it as a complete module.

8) Fintual: taxes and actions (and why the question comes up so much)

The keyword “fintual taxes actions” It usually comes because people invest from apps and assume: “if it's digital, it's already solved”.

In general, platforms such as Fintual:

  • they provide useful information/certificates,
  • but your final tax liability depends on your situation and if you have other instruments (direct stocks, foreign brokers, trading, etc.).

Rule of thumb:
If you only had a simple product, it can be easy.
If you mix funds + stocks outside + trading, you need a Order system.

9) Annual checklist to declare without improvising

If you want to avoid the “March of Panic”, use this checklist now:

9.1 Minimum date

  • Monthly cards for all accounts (Chile and abroad).
  • Consolidated annual statement.
  • Dividend/Interest Report.
  • Purchase/sale confirmations.
  • Commissions and fees.

9.2 Tax Order

  • Tax cost recording by instrument.
  • FX control (consistent criteria).
  • Reconciliation: broker vs statement.

9.3 Back-up

  • Annual folder per broker + per instrument.
  • Working papers (how did you calculate).
  • Evidence of corporate events.

10) When should we ask for help (and what do we do differently)?

If you identify with any of these scenarios, advice is usually appropriate:

  • “I have investments in Chile and abroad and I don't know which Affidavit applies to me.”
  • “I made sales, dividends and trading: my Excel doesn't add up.”
  • “I have several currencies, several brokers, and I want to sleep peacefully with the SII.”
  • “I don't want to rectify three years later because 'a report was missing'.”
