The Chilean Internal Revenue Service (SII, for its initials in Spanish) maintains a schedule of monthly and annual tax obligations, including specific tax filing and payment deadlines, together with the penalties applicable in the event of non-compliance. Furthermore, the amendments introduced by the National Reconstruction and Economic and Social Development Bill may impact certain tax obligations starting in 2027. 

Accordingly, it is essential for taxpayers to periodically review official SII guidance and confirm the deadlines applicable to their individual tax circumstances. 

Where can taxpayers find the official calendar? 

SII provides a range of tools that taxpayers can use to verify filing deadlines and comply with their tax obligations: 

• Interactive tax calendar 2026: allows taxpayers to look up filing and payment deadlines by date or type of tax procedure, identifying the specific due dates applicable to each. 

• Key filing deadlines for affidavits: The deadlines applicable to the 2027 income tax filing process (Operación Renta, in Spanish) have not yet been published. The official affidavit filing calendar is established through a resolution that is typically issued in mid-September of each tax year. However, filing deadlines generally remain largely unchanged from those applied in the previous year.

Accordingly, late filing or failure to file may result in: 

• Fines for late submission or non-filing. 

• Surcharges on outstanding tax liabilities. 

• Interest charges for late payments. 

The amount of these penalties will depend on the nature of the non-compliance and the length of time that has elapsed since the filing or payment deadline. 

These penalties apply separately to each tax reported on the form. 

Annual obligations 

1. Form 22 (Annual income tax return) 

What must be reported? 

Form 22 is the annual income tax return for both individuals and legal entities. It must be filed in accordance with the tax regime applicable to each taxpayer. Information regarding the applicable tax regime can be consulted on the website of the Chilean Internal Revenue Service (SII, for its initials in Spanish). 

Filing deadlines 

Although the filing deadlines for the Tax Year 2027 have not yet been published, they have traditionally remained largely unchanged from year to year. Based on the Tax Year 2026 calendar, the annual income tax filing season typically begins in April and concludes in May. 

April 

• Day 1: opening of the filing period for Form 22 (Annual Income Tax Return) with no payment due. 

• Day 8: opening of the filing period for Form 22 with payment due. 

• Day 24: taxpayers who identify errors in a return filed online without payment may replace the return until April 26. After that date, any amendments must be submitted through the amended return process. 

• Day 29: deadline for filing the Annual Income Tax Return online with payment through Electronic Bill Payment (PEC), under which the taxpayer authorizes the bank to debit a checking account. 

• Day 30: Deadline for filing the Annual Income Tax Return online with payment through Online Payment (PEL), using either a checking account or a credit card. 

May 

• Day 8: deadline for filing Form 22 (Annual Income Tax Return) online with no payment due. 

Penalties for late filing 

The penalties applicable to late filing vary depending on the outcome of the return and whether any taxes are due. 

Tax returns with payment due 

When a tax return showing an amount payable is filed after the statutory deadline: 

• Any tax paid late is subject to inflation adjustment based on changes in the Consumer Price Index (IPC, for its initials in Spanish). For this purpose, the adjustment is calculated using the percentage increase in the IPC between the last day of the second month preceding the due date and the last day of the second month preceding payment. For example, if an Income Tax Return was due in April and the tax is paid in June, the adjustment would be calculated based on the IPC variation between February and April. 

• A penalty equal to 10% of the outstanding tax liability applies when the delay does not exceed five months. 

• After that period, the penalty increases by an additional 2% for each month or fraction thereof of delay, up to a maximum of 30% of the tax due. 

• In addition, interest of 1.5% per month or fraction of a month is charged for late payment. 

Returns claiming a refund 

When a return that gives rise to a tax refund is filed late, the applicable fine may range from one Monthly Tax Unit (UTM) to one Annual Tax Unit (UTA, for its initials in Spanish). 

Returns with no payment due 

For returns with no tax payable, no activity, or so-called “matched returns” (neither tax payable nor refund due), the fine may likewise range from one UTM to one UTA. 

Incomplete or incorrect returns 

The filing of an incomplete or incorrect return is subject to penalties under Article 109 of the Chilean Tax Code. The amount of the penalty is determined based on factors such as the number of amended returns filed and the number of cases reported. 

2. Affidavits for the Annual Income Tax filing process  

Filing deadlines 

The filing deadlines vary depending on the specific affidavit. Some affidavits must be filed monthly, while others are filed annually. 

The principal annual affidavits are generally due between January and July, with the highest concentration of filing obligations occurring in March. 

Monthly affidavits 

The main monthly affidavits include: 

• Form F1820: due on the last business day of the month. 

• Form F1839: due on the last business day of each month. 

• Form F1842: due on the last day of the month in which Form 29 must be filed. 

• Form F1921: due on the last business day of the month following the transfer of shares, partnership interests, securities, or rights in a foreign company or entity.

The SII penalty schedule for Tax Year 2026 establishes progressive penalties based on the type of return, the number of records reported, and the number of days of delay. Depending on the nature and severity of the non-compliance, the base fine may range from fractions of a Monthly Tax Unit (UTM) to several Annual Tax Units (UTA). 

Special penalties

Reconstruction Law and its implications for Tax Returns and Forms 

Key measures included  

• Gradual reduction of the First Category Income Tax Rate: the Act provides for a progressive reduction of the First Category Income Tax rate from the current 27% to 23% for taxpayers subject to the general tax regime. 

• Elimination of tax on certain capital gains from publicly traded securities: capital gains derived from the sale of shares, investment fund units, and other publicly traded instruments would no longer be subject to the 10% single tax, instead being treated as non-taxable income. This change could affect certain items reported on Form 22. 

• Reintegration of the Tax System: the reform allows the First Category Income Tax paid by a company to be fully credited against the final taxes payable by its owners. 

• Temporary VAT exemption for the sale of new residential properties: a temporary 12-month VAT exemption is introduced for the sale of new homes, which could affect the calculation and reporting of VAT through Form 29. For further information, see the Reconstruction Law Plan Measures. 

• Incentives for formal employment: the Act includes measures designed to promote the hiring and retention of formally employed workers, including tax benefits linked to payroll expenses and other employment-support mechanisms. 

Recommendations 

To ensure proper management of tax obligations, taxpayers are advised to: 

1. Regularly consult the SII Interactive Tax Calendar to verify the deadlines applicable to their specific circumstances. 

2. Review, in a timely manner, the affidavits and information returns required from the company, with their respective filing deadlines. 

3. Verify the official deadlines published by the SII, particularly when holidays or regulatory changes may affect filing schedules. 

4. Bear in mind that the filing dates for the Annual Tax Filing 2027 have not yet been published and that the dates referenced in this note are based on the Tax Year 2026 calendar. 

5. Monitor developments regarding the review before the Constitutional Court, the subsequent enactment and publication of the Reconstruction Law and any guidance or implementation of instructions issued by the SII.
