This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem or hold all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. The example reflects the fee waiver and/or expense reimbursement described above (if any) through the expiration of such waiver and/or reimbursement and total annual fund operating expenses thereafter. You may be required to pay brokerage commissions on your purchases and sales of Class F-2 or F-3 shares of the fund, which are not reflected in the example.

Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s investment results. During the most recent fiscal year, the fund’s portfolio turnover rate was 12% of the average value of its portfolio.

Strategy [Heading] oef_StrategyHeading Principal investment strategies
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

The fund seeks to achieve its objectives by primarily investing in municipal bonds issued by the state of New York and its agencies and municipalities. Consistent with the fund’s objectives, the fund may also invest in municipal securities that are issued by jurisdictions outside New York. Municipal bonds are debt obligations generally issued to obtain funds for various public purposes, including the construction of public facilities. The fund may also invest in bonds exempt from federal and state taxation that are used to fund private projects.

Under normal circumstances, the fund will invest at least 80% of its assets in, or derive at least 80% of its income from, securities that are exempt from regular federal, New York state and New York City income taxes and that do not subject you to federal alternative minimum tax. Investments in derivatives may be counted toward the fund’s 80% investment policy to the extent that such derivatives provide investment exposure to the investments included within the policy or to one or more market risk factors associated with such investments. The fund may also invest up to 20% of its assets in “private activity bonds” whose interest is generally subject to the federal alternative minimum tax. The fund is intended primarily for taxable residents of New York.

The fund will invest primarily in debt securities rated BBB- or better or Baa3 or better by Nationally Recognized Statistical Rating Organizations designated by the fund's investment adviser, or unrated but determined by the fund's investment adviser to be of equivalent quality. The fund may invest up to 10% of its assets in debt securities rated BB+ or below and Ba1 or below by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser, or unrated but determined by the fund’s investment adviser to be of equivalent quality. Such securities are sometimes referred to as “junk bonds.”

The fund is nondiversified, which allows it to invest a greater percentage of its assets in any one issuer than would otherwise be the case.

The fund’s assets are managed by a team of portfolio managers. Under this approach, the fund’s portfolio managers will work together to oversee the fund’s entire portfolio.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively priced securities that, in its opinion, represent good, long-term investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

AMERICAN FUNDS TAX-EXEMPT FUND OF NEW YORK | Risks of investing in municipal bonds of issuers within the state of New York [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Risks of investing in municipal bonds of issuers within the state of New York — Because the fund invests primarily in securities of issuers within the state of New York, the fund is more susceptible to factors adversely affecting issuers of New York securities than a comparable municipal bond mutual fund that does not concentrate its investments in a single state. For example, such factors may include political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial or economic difficulties, and changes in the credit ratings assigned to New York’s municipal issuers. New York’s economy and finances may be especially vulnerable to changes in the performance of the financial services sector, which historically has been volatile. More detailed information about the risks of investing in New York municipal securities is contained in the statement of additional information.
AMERICAN FUNDS TAX-EXEMPT FUND OF NEW YORK | Market conditions [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Market conditions — The prices of, and the income generated by, the securities held by the fund may decline – sometimes rapidly or unpredictably – due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Economic, financial or political events, trading and tariff arrangements, wars, terrorism, cybersecurity events, natural disasters, public health emergencies (such as the spread of infectious disease), bank failures and other circumstances in one country or region, including actions taken by governmental or quasi-governmental authorities in response to any of the foregoing, could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund’s investments may be negatively affected by developments in other countries and regions.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Issuer risks — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer’s goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer’s financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.
AMERICAN FUNDS TAX-EXEMPT FUND OF NEW YORK | Investing in municipal securities [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Investing in municipal securities — Municipal securities are debt obligations that are exempt from federal, state and/or local income taxes. The yield and/or value of the fund’s investments in municipal securities may be adversely affected by events tied to the municipal securities markets, which can be very volatile and significantly impacted by unfavorable legislative or political developments and negative changes in the financial conditions of municipal securities issuers and the economy. To the extent the fund invests in obligations of a municipal issuer, the volatility, credit quality and performance of the fund may be adversely impacted by local political and economic conditions of the issuer. For example, a credit rating downgrade, bond default or bankruptcy involving an issuer within a particular state or territory could affect the market values and marketability of many or all municipal obligations of that state or territory. Income from municipal securities held by the fund could also be declared taxable because of changes in tax laws or interpretations by taxing authorities or as a

result of noncompliant conduct of a municipal issuer. Additionally, the relative amount of publicly available information about municipal securities is generally less than that for corporate securities.
AMERICAN FUNDS TAX-EXEMPT FUND OF NEW YORK | Investing in debt instruments [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Investing in debt instruments — The prices of, and the income generated by, bonds and other debt securities held by the fund may be affected by factors such as the interest rates, maturities and credit quality of these securities.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. Also, when interest rates rise, issuers of debt securities that may be prepaid at any time, such as mortgage- or other asset-backed securities, are less likely to refinance existing debt securities, causing the average life of such securities to extend. A general change in interest rates may cause investors to sell debt securities on a large scale, which could also adversely affect the price and liquidity of debt securities and could also result in increased redemptions from the fund. Falling interest rates may cause an issuer to redeem, call or refinance a debt security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities.

Bonds and other debt securities are also subject to credit risk, which is the possibility that the credit strength of an issuer or guarantor will weaken or be perceived to be weaker, and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default. Changes in actual or perceived creditworthiness may occur quickly. A downgrade or default affecting any of the fund’s securities could cause the value of the fund’s shares to decrease. Lower quality debt securities generally have higher rates of interest and may be subject to greater price fluctuations than higher quality debt securities. Credit risk is gauged, in part, by the credit ratings of the debt securities in which the fund invests. However, ratings are only the opinions of the rating agencies issuing them and are not guarantees as to credit quality or an evaluation of market risk. The fund’s investment adviser relies on its own credit analysts to research issuers and issues in assessing credit and default risks.
AMERICAN FUNDS TAX-EXEMPT FUND OF NEW YORK | Liquidity risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Liquidity risk — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss.

Credit and liquidity support — Changes in the credit quality of banks and financial institutions providing credit and liquidity support features with respect to securities held by the fund could cause the values of these securities to decline.

Risk [Text Block] oef_RiskTextBlock

Investing in lower rated debt instruments — Lower rated debt securities or instruments, rated Ba1/BB+ or below by Nationally Recognized Statistical Rating Organizations (also known as "junk bonds"), generally have higher rates of interest and involve greater risk of default or price declines due to changes in the issuer’s creditworthiness than those of higher quality debt securities. The market prices of these securities may fluctuate more than the prices of higher quality debt securities and may decline significantly in periods of general economic difficulty.

AMERICAN FUNDS TAX-EXEMPT FUND OF NEW YORK | Investing in similar municipal bonds [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Investing in similar municipal bonds — Investing significantly in municipal obligations of multiple issuers in the same state or backed by revenues of similar types of projects or industries may make the fund more susceptible to certain economic, political or regulatory occurrences. As a result, the fund has greater risk of volatility, and greater risk of loss, from these investments.
AMERICAN FUNDS TAX-EXEMPT FUND OF NEW YORK | Risk Nondiversified Status [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Nondiversification — As a nondiversified fund, the fund may invest a greater percentage of its assets in fewer issuers than a diversified fund. A fund that invests in a relatively smaller number of issuers is more susceptible to risks associated with a single economic, political, geographic or regulatory occurrence than a diversified fund might be. In addition, poor performance by a single issuer could adversely affect fund performance more than if the fund were invested in a larger number of issuers. The value of the fund’s shares can be expected to fluctuate more than might be the case if the fund were more broadly diversified.

Management — The investment adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.
