10.2 Income tax In accordance with Law 2010/2019 and Laws 2155/2021 and 2277/2022, the tax provisions applicable in Colombia for taxable years 2022 and 2023, are the following:
| ● | The income tax rate applicable to national companies and foreign entities operating in Colombia will be 35% for 2022 and beyond.
| ● | From the year 2021, the presumptive income rate was 0% of the taxpayer’s net equity from the immediately previous year.
| ● | The income tax for tax free trade zone users will be 20%. If the company located in the free zone has a Legal Stability Agreement (hereinafter LSA), the income tax rate is 15% during the term of said contract. This is the case of Refinería de Cartagena S.A.S. until 2023 and Esenttia Masterbatch Ltda. until 2028.
| ● | For fiscal years 2022 and 2023, Ecopetrol Business Group has subsidiaries that are subject to 35% income tax rate, subsidiaries located in free trade zones (Refinería de Cartagena and Esenttia Masterbatch Ltda.) that were subject to a 15% income tax rate depending upon whether they complied with the Legal Stability Contract (LSA) rules and other subsidiaries in Brazil, Chile, Perú, USA, that were subject to 34%, 27%, 29.5%, 21%, respectively.
| ● | For Ecopetrol S.A. and Hocol, additional surcharge must be added to the general income tax rate of 35%. This surcharge will be calculated taking as reference the average Brent price of the last 10 years, which will be updated by the inflation index of the United States of America to update them to values constants. Based on these, the percentiles that give rise to the additional surcharge to the general rate are determined as indicated below:
​
​ | ​ | ​ | ​
< percentile 30 |  | 0 | %
> = to percentile 30 and < to percentile 45 |  | 5 | %
> = to percentile 45 and < to percentile 60 |  | 10 | %
> = to percentile 60 |  | 15 | %
​
| ● | The tax depreciation percentages are adjusted based on the table established in Law 1819 of 2016. On the other hand, oil investments depletion will be calculated based on the technical production units as it is recorded for accounting purposes.
| ● | Expenses for the acquisition of exploration rights, geology and geophysics, exploratory drilling, among others, are capitalizable until the technical feasibility and commercial viability of extracting the resource are determined.
| ● | Fluctuations in items expressed in foreign currency will only have tax effects at the time of disposal or payment in the case of assets, or liquidation or partial payment in the case of liabilities.
| ● | Tax losses generated as of January 1, 2017, may be offset against ordinary net income obtained in the following 12 taxable years, except for companies that have signed a legal stability contract, and included within it the article that they contemplated that tax losses did not have an expiration date.
Related to income tax in other countries in which the Business Group operates, the following are the main aspects to consider: Peru
| ● | Current income tax rate is 29.5% on the taxable income after deducting the employes participation, which is calculated with a rate of 5% or 10% on the taxable income.
| ● | Dividends and other forms of profit distribution are subject 5% income tax rate.
| ● | From 2021, the financial expenses deduction is limited to 30% of tax Ebitda.
| ● | Intra-group services deduction is allowed for low value-added services to the extent that the deductible amount does not exceed expenses and costs plus a 5% margin.
Brazil
| ● | Legal entities income tax and Social Contribution on Liquid Profits are federal taxes that affect the income of the legal entity in its real or presumed profit.
| ● | Real profit: Tax is determined based on the results for each period, establishing the taxable base considering the accounting profit and performing the depurations determined in tax legislation. All income and returns on capital are included in the calculation base. The 34% rate is applied to the taxable base of liquid profit.
| ● | Presumed profit: it is a simplified form taxation for the calculation base. Applies to legal entities that have gross income up to BRL $78 million in the immediately preceding year. In this system, the tax base is determined by applying the rate of 8%, 12% or 32% to gross income (the rate to be applied depends on the activity carried out by the taxpayer) and the rate of 34% is applied to the result.
Statute of limitations of tax returns In Colombia, the income tax returns of the taxable years 2011, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, and 2022 and income tax for equality - CREE - of the taxable years 2014, 2015, and 2016 can still be reviewed by the tax authorities. The management of Ecopetrol Business Group considers that the amounts recorded as liabilities for taxes payable are sufficient and are supported by the law to meet any claim that may be established with respect to such years. In Colombia, as of January 1, 2017, the statute of limitations for the income tax return corresponds to three-year (3) counted from the due date to file the return or the filing date, when these have been lately filed. In the case of Ecopetrol S.A., because it is subject to compliance with transfer pricing rules, the final term is 6 years. However, Law 2010 of 2019 established that this term will be 5 years, for returns submitted after January 1, 2020. For the years 2022 and 2023, in accordance with Law 2155 of 2021, the time in which the tax authorities can audit an income tax return is reduced, which goes from 5 years to between 6 to 12 months, depending on if the net income increased to 35% or 25% compared to that was declared in the immediately previous year. Regarding those returns in which balances are presented in favor, the final term is 3 years, from the date of presentation of the request for refund or compensation. Starting in 2020, tax returns that present tax losses can be reviewed by tax authorities within 5 years from the date of filing and/or correction. Income tax expense ​

​ Deferred tax assets not recognized Deferred tax assets related to tax loss carryforwards incurred by the subsidiaries of ISA Group: Ruta del Bosque (Chile) for $100,356 (2022 – $102,864), Ruta del Maule (Chile) for $36,138 (2022 - $43,702), ISA Interconexiones Viales for $3,094, ISA Inversiones Costeras Chile for $39,221, Internexa Chile for $12,859, ISA Inversiones Chile Ltda. for $39,161, ISA Intervial Colombia for $542 (2022: $564), ISA Capital Do Brasil for $17,093 (2022:$20,216), Internexa Brasil Operadora de Telecomunicações for $95,226 (2022:$101,525), Internexa Participações (Brasil) for $2,579(2022:$2,913) and ISA Bolivia for $4,934 (2022:$4,142), are not recognized, since Management has assessed and reached the conclusion that it is not probable that the deferred tax asset related to these tax losses and presumptive excess income is recoverable in foreseeable future. If Ecopetrol Business Group had been able to recognize the unrecognized deferred tax asset, the profit for the year ended December 31, 2023, would have increased by $351,203 (2022 - $363,158). With respect to the additional income surtax, deferred tax assets corresponding to the estimated surcharge for the years 2026 and following are not recognized because there is no certainty about the proportion of the deferred that will be recovered in each of these years. Deferred tax liabilities (assets) not recognized in subsidiaries As of December 31, 2023, in connection with paragraph 39 of IAS 12 deferred tax liabilities are not recognized on the difference between the accounting and tax bases associated with investments in subsidiaries, joint ventures of Ecopetrol S.A.

(Base: $11,573 Tax: $1,736). Minimum Tax Rate (Colombia Tax Law) In accordance with numeral 2 of paragraph 6 of article 240 of the Tax Code, taxpayers who are tax residents in Colombia whose financial statements are subject to consolidation must calculate the adjusted tax rate in a consolidated manner. For the taxable year 2023, according to the calculation made by Ecopetrol, the minimum tax rate of the companies with tax residence in Colombia of the Ecopetrol Group is greater than 15%. Given the above, the company does not recognize an additional expense for this concept. ​

​ Pillar II The Ecopetrol Group has a presence in the jurisdictions of Argentina, Bahamas, Brazil, Bolivia, Cayman, Chile, Colombia, Spain, United States, Mexico, Peru, Singapore, and Switzerland. The Ecopetrol Group reviewed its corporate structure in order to determine possible impacts of the introduction of the Pillar model rules, as well as to determine the progress of each jurisdiction in implementing this international standard. The ongoing assessment is based on the most recent tax returns and country-by-country report for the year 2022, as well as the most up-to-date financial information for the year 2023. From the analysis carried out on the implementation of Pillar II in those countries in which in which the Company has a presence, it was identified that in some of them the regulations were issued to establish the Qualified Domestic Minimum Top-up Tax (QDMTT) as of January 1, 2024. However, no country has established internal regulations for the Income Inclusion Rule (IIR) and the Undertaxed Profits Rule (UTPR), which means that there are no tools associated with Pillar II that allow access to the income tax of other jurisdictions, whose Effective Tax Rate is less than 15%. Currently, the Ecopetrol Business Group is unable to provide information on potential exposure to Pillar II income taxes, considering that in the jurisdictions in which Ecopetrol operates, although countries such as Spain and Switzerland have adopted Pillar II in their domestic legislation, there are still delays in the implementation of the payment rules as of December 31, 2023. The Business Group will continue monitoring the implementation of BEPS 2.0 in jurisdictions that already have progress. Additionally, the Company will work in 2024 on the assessment and calculation of the global minimum tax rate. Notwithstanding, based on the mandatory temporary exception contemplated in the Amendment to IAS12, Ecopetrol Business Group does not recognize deferred tax assets or liabilities associated with the Pillar II income taxes, in its consolidated financial statement for taxable year 2023. Uncertain tax positions - IFRIC 23 Ecopetrol Business Group’s strategy is to avoid making aggressive tax decisions that may cause questioning of its tax returns, by tax authorities. Regarding uncertain tax positions where it has been determined that there may be a possible controversy with the tax authority that could result in an income tax increase, a success threshold has been established by IFRIC 23, which has been calculated based on current regulations and tax opinion provided by our tax advisors. In accordance with the aforementioned interpretation, the Ecopetrol Business Group considers that uncertain tax positions included in its determination of income tax will not affect the results if it is probable that the position will be accepted by the tax authorities. Notwithstanding, the Ecopetrol Business Group will continue to monitor new tax regulations and ruling issued by the tax authority and other entities. 10.3.Other taxes Dividend taxes Starting on the profits generated from the year 2017, the tax on dividends applies to resident natural persons, national companies, and foreign entities. Law 1943 of 2018 established that, as of January 1, 2019, dividends and participations paid or credited to the account from profit distributions that have been considered as income that does not constitute income or occasional profit between Colombian companies, are subject to a withholding for dividend tax at a rate of 10% from 2022 according to Law 2277 of 2022. This withholding is transferable to the final beneficiary, foreign entity, or natural person tax resident in Colombia. On the other hand, if the profits charged to which the dividends were distributed were not subject to tax at the company level, said dividends are taxed with the income tax applicable in the period of distribution. In this case, the 10% withholding will apply to the value of the dividend once decreased with the income tax (35% for the year 2023). The non-taxed dividends that the Ecopetrol Business Group will receive will not be subject to withholding at source by express provision of the regulation, which states that dividends distributed within business groups duly registered with the Chamber of Commerce, to decentralized entities or Colombian Holding Companies, they will not be subject to withholding at source for this concept. Transfer prices In Colombia, income taxpayers who enter into operations with economic associates or related parties from abroad and located in free zones, or with residents located in countries considered non-cooperative jurisdictions with low or no taxation, are required to determine for income tax purposes, their ordinary and extraordinary revenue, their costs and deductions, assets and liabilities, considering for these operations the prices and profit margins that would have been used in comparable operations with or between those not economically related. Ecopetrol Business Group submitted in 2023 the transfer pricing information for 2022 corresponding to the informative return, the supporting documentation, the country-by-country report, and the master file, in accordance with current tax regulations. For the taxable year 2023, the transactions with economic related parties abroad, as well as the business conditions under which such operations were made and the general structure, did not vary significantly with respect to the previous year. For this reason, it is possible to infer that said transactions were recognized in accordance with the arm’s length principle. It is estimated that no adjustments related to the transfer pricing analysis of the year 2023 will be required, which imply changes in the income provision of the same year. Value Added Tax The VAT already paid by the user of the free zone is excluded from the basis to settle the VAT on imports of goods from the free zone. Article 491 of the Tax Code expressly prohibits the possibility to consider the VAT paid on the acquisition of fixed assets as deductible tax. In addition, three VAT exemption days a year are established in Colombia for certain products, with limits depending on the units purchased. Additionally, the list of goods and services excluded from VAT enshrined in articles 424, 426, and 476 of the Tax Code was modified, and article 437 of the Tax Code was added, regarding guidelines on compliance with formal duties regarding to VAT on the part of service providers from abroad and it was indicated that VAT withholding may be up to 50% of the value of the tax, subject to regulation by the National Government. The VAT rate remains at 19%. (Art. 424, Art. 426, Art. 476 Tax Code). Tax procedures In terms of procedure, there are modifications: (i) withholding that, despite being ineffective, will be enforceable, (ii) electronic notification of administrative acts, (iii) payment of glosses in the statement of objections to avoid default interest, (iv) elimination of the extension of the finality to additional three years for offsetting of tax losses, and (v) the term of the finality will be 5 years, compared to the years in which there is an obligation to comply with the transfer pricing regime. In addition, an audit benefit was included for taxable years 2020 and 2021. By virtue of this benefit, the private settlement of income taxpayers and complementary taxpayers who increase their net income tax by at least a percentage a minimum of 30%, related to the net income tax of the immediately preceding year, will become final within six months after the date of presentation if a notification to correct or special requirement has been notified, or provisional settlement and, considering that the declaration must be presented in a timely manner and the payment must be made within the established deadlines. If the increase in the net income tax is at least 20% over the net income tax of the immediately preceding year, shall be considered for twelve (12) months, after the date the presentation if not notified of a deadline for correction or special requirement, or a special deadline or provisional settlement, provided that the return is filed timely, and the payment is made within the established deadlines. The above benefit does not apply to: (i) taxpayers who enjoy tax benefits due to their location in a specific geographical area; (ii) when it is shown that declared withholdings are non-existent; (iii) when the net income tax is less than 71 UVT ($24). The term set forth in this regulation does not extend to declarations of withholding or sales tax, which will be governed by the general regulations. ​ Law 2155 of September 14, 2021 - Colombia In general terms, this reform increased the general income tax rate to 35% as of January 1, 2022 and maintained the discount for the Industry and Commerce Tax at 50%. This Tax Reform introduced other changes in value added tax and tax procedure obligations. Before the passing of this Law, the rate from the year 2022 was 30% and the discount of the Industry and Commerce Tax was 100%. Audit benefit: For the fiscal years 2022 and 2023, this Law reduces the time in which the tax authorities can audit an income tax return, from 5 years to between 6 to 12 months, depending on whether the net income tax increased to 35% or 25% with respect to that income tax return in the last fiscal year. Works for Taxes Mechanism: The assumptions under which the “works for taxes” can be accessed are expanded, including those territories that, not being ZOMAC, are in some of these situations: (i) They have high rates of poverty, (ii) totally or partially lack infrastructure for the provision of residential public services, (iii) are in non-interconnected areas and (iv) are in Orange Development Areas (ADN acronyms in Spanish). This mechanism will also be applicable to those projects declared of national importance that are strategic for the economic and/or social reactivation of the Nation, even if they are not located in the previous territories (subject to the approval of the Ministry of Finance and Public Credit in Colombia). Tax reform Law 2277 of December 13, 2022 The most relevant aspects of this reform in the Business Group’s taxes. Non-deductibility of royalties: The deductibility of oil royalties paid to the Colombian Government for the exploitation of non-renewable resources is restricted, regardless of the denomination of the payment. On November 16, 2023, the Constitutional Court in Colombia issued ruling C-489 in which it determined that royalties are a deductible cost of income tax. In December 2023, the Ministry of Mines and Energy and the Ministry of Finance and Public Credit requested the Constitutional Court to review the ruling issued, alleging a fiscal impact and its nullity. Given that the National Government has not filed the corresponding request, the Constitutional Court has not issued any consideration. If the Court decides to modulate the effects of the judgment issued in November 2023, the effects must be reflected in 2024. Free zone rate: The rate of taxable income and complementary taxes applicable to offshore free zones; industrial users of special permanent free zones for port services, industrial users of special permanent free zones, whose main corporate purpose is the refining of petroleum-derived fuels or refining of industrial biofuels; industrial users of services that provide the logistics services of numeral 1 of article 3 of Law 1004 of 2005 and operator users, will be 20%. Minimum tax rate: A minimum tax rate is established for income taxpayers, which will be calculated from the adjusted financial profit, which may not be less than 15% and will be the result of dividing the adjusted tax on the net profit. A minimum tax rate of 15% is introduced for income taxpayers. This minimum rate is called the adjusted tax rate and cannot be less than 15%. This rate is determined by dividing the adjusted tax by the adjusted profit. In turn, the factors that make up the adjusted profit and the tax are established to delimit their determination. If the adjusted tax rate is less than 15%, there must be an adjusted to recognize the minimum 15%. This minimum taxation does not apply in several cases, including foreign legal entities without residence in the country; Special Economic and Social Zones, during the period that their income tax rate is 0%; the ZOMAC; income from hotel services subject to a 15% rate; publishing companies with the exclusive corporate purpose of publishing books; industrial and mixed economy companies in the Government with a 9% rate; and concession contracts. Taxation of non-resident entities with significant economic presence in Colombia: Non-residents that sell goods and/or provide certain digital services (listed in the standard) to people located in Colombia, could have a significant economic presence in the country and would be subject to a withholding tax of 10%, or they could choose to file an income tax return and apply a 3% rate on gross income. Significant economic presence would exist when the non-resident (also considering its related parties):
| ● | Obtains gross income greater than 31,300 UVT for transactions with people located in Colombia.
| ● | Has a systematic and deliberate interaction with the Colombian market. The above is presumed to happen if an interaction or marketing deployment is maintained with 300,000 or more users located in Colombia, or if there is the possibility of viewing prices in Colombian pesos (COP) or allowing payment in this currency.
Discount for investments made in research, technological development, or innovation: Investments in projects qualified by the National Council of Tax Benefits in Science and Technology in Innovation will have the right to discount 30% of the value invested in said income tax projects in the taxable period in which the investment was made. It is not possible to take the cost or deduction simultaneously with the discount. Tax benefits and incentives limits: For income taxpayers, other than natural persons and illiquid successions, the value of income that does not constitute income for tax purposes or occasional gain, special deductions, exempt income, and tax discounts may not exceed the 3% per year of ordinary liquid income before deducting the special deductions contemplated in the regulations. Industry and commerce tax deduction: The industry and commerce tax paid will be 100% deductible as of taxable year 2023, it can no longer be treated as a tax discount. Dividend tax: Dividends and shares paid to national companies will be subject to the rate of ten percent (10%) as withholding tax on income, which will be transferable and attributable to the natural person (resident or resident investor abroad). The income tax rate applicable to dividends and shares paid to permanent establishments in Colombia of foreign companies will be 20%. Concurrent benefits: The prohibition of taking concurrent tax benefits is extended to exempt income, revenue that does not constitute income for tax purposes or occasional gain, and the reduction of the income tax rate.
