Purpose This Note provides guidance on the application of section 66(13C) and the discretionary power vested in the Commissioner to accept financial accounts of a company for a period ending on a day that differs from the last day of the company’s financial year. The position of persons other than companies, for example, natural persons or trusts is dealt with in Interpretation Note 19 “Year of Assessment of Persons other than Companies: Accounts Accepted to a Date other than the Last Day of February”. 1 See section 3(1). 2. Background A company’s year of assessment is generally its financial year.2 Companies are occasionally required to close their financial accounts earlier or later than the last day of their financial year for various reasons. Section 66(13C) allows companies to align reporting for tax purposes with the period ending on the day their financial accounts are closed. 3. The law The relevant provisions of the Act are quoted in the Annexure. 4. Application of the law 4.1 Definitions of “year of assessment” and “financial year” [section 1(1)] The term “year of assessment” as defined in section 1(1) provides that a company’s year of assessment is its financial year. Under section 5(1)(d), a company shall pay income tax annually on the taxable income received by, accrued to or in favour of it during every financial year. The term “financial year” is also defined in section 1(1). In the case of – • a newly incorporated company, the financial year is the period, whether of 12 months or not, commencing on the date of incorporation and ending on the last day of February immediately succeeding that date or on any other date approved by the Commissioner having regard to the circumstances of the case; and • any other company, any period subsequent to the period referred to above, whether of 12 months or not, commencing immediately after the last day of the immediately preceding financial year of that company and ending upon the first anniversary of such last day or upon such other date as the Commissioner having regard to the circumstances of the case may approve. If, for example, a company’s financial year ends on 30 June, the Commissioner may approve that the financial year for income tax purposes, as defined in section 1(1), also ends on 30 June. The year of assessment is, by definition, the same as the financial year for income tax purposes. When a company changes its financial year for Companies Act3 purposes, the Commissioner may also approve a corresponding change in the financial year for income tax purposes. The Commissioner’s discretionary power under the definition of “financial year” is not subject to the Companies Act. Accordingly, in approving a company’s financial year, the Commissioner may, but is not obligated to, take into account the requirements of the Companies Act and to align the financial year for income tax purposes with the financial year for Companies Act purposes. Amongst other things, section 27 of the Companies Act provides that – • a company’s financial year may not exceed 15 months (this applies to its first financial year and any subsequent financial year which is longer than 12 months as a result of a change in financial year); 2 The terms “year of assessment” and “financial year” are defined in section 1(1) – see 4.1. 3 See section 27(4) of the Companies Act. • a company may not file a notice to change its financial year more than once during a financial year; and • in the case of a change in financial year, the newly established financial year- end must be later than the date on which the notice is filed. The Companies Act does not lay down a minimum period for a financial year. A company incorporated on 1 February which adopts a financial year-end of the last day of February would thus have a first financial year of one month. Generally, the approval of a company’s first financial year does not present any difficulty and the Commissioner will often approve the financial year adopted by the company for purposes of section 27 of the Companies Act. In the unlikely event of a company not specifying a financial year, its financial year will be the last day of February. If the Commissioner does not agree to change a company’s financial year-end for a specific year of assessment and the financial year for income tax purposes does not align with the financial year under the Companies Act, that company will need to draw up separate sets of financial statements for income tax purposes and for Companies Act purposes. Non-approval can happen, for example, if an application carries negative consequences for the fiscus, such as a decrease in tax rates or enhanced capital allowances. The Commissioner will approve such an application only in exceptional circumstances or may approve it subject to the change taking effect in the following fiscal year. The Commissioner’s discretion in the definition of “financial year” to approve other dates is not subject to objection and appeal.4 Section 3(1) provides that the powers conferred and duties imposed upon the Commissioner by or under the provisions of the Act, may be exercised or performed by the Commissioner or by any officer under the control, direction or supervision of the Commissioner. A decision made by a SARS official or a notice to a specific person issued by SARS under a tax Act, excluding a decision given effect to in an assessment or a notice of assessment that is subject to objection and appeal, may in the discretion of a SARS official listed below or at the request of the relevant person, be withdrawn or amended by – • the SARS official; • a SARS official to whom the SARS official reports; or • a senior SARS official.5 The following are examples of valid reasons for a company requesting a change in financial year: • A company’s operations are based on seasonal clientele. As a result, the company has a mid-year peak followed by a period of low activity. At inception of the company the directors set the financial year at 30 June without taking into account the seasonal nature of the company’s business. They now want to change the year-end to 31 October when stock levels and sales are low. 4 Section 3(4)(a) does not include the definition of “financial year”. 5 Section 9(1) of the TA Act. The revised year-end will make stocktaking much easier as well as simplifying accounting cut-off procedures. • A company in the retail industry has a December financial year. The pressure of the holiday season has resulted in an administrative burden for the company because of elevated stock levels and the volume of transactions around year- end. The company applies to change its financial year to the last day of February. Example 1 – Rejection of change in financial year Facts: In the Budget Speech on 21 February 20x2 the Minister announced that the corporate tax rate would decrease from 28% to 27% for companies with years of assessment ending between 1 April 20x2 and 31 March 20x3. On 22 February 20x2 Company A applied to the Commissioner to change its financial year from 28 February 20x2 to 30 April 20x2 citing various commercial reasons, none of which involved exceptional circumstances. Result: Since there were no exceptional circumstances justifying the application and in view of the negative consequences for the fiscus, SARS notified the company that its request could not be accepted. Company A was given the option of changing its financial year-end to 30 April 20x3 (that is, its first amended financial year would run from 1 March 20x2 to 30 April 20x3, a period of 14 months). 4.2 Financial accounts drawn up for a period that differs from the financial year [section 66(13C)] Section 66(13C) provides that if a company does not close its financial accounts on the last day of its financial year, the Commissioner may accept the financial accounts in respect of its income drawn to a fixed day approved by the Commissioner. Such a request should be submitted to the Commissioner within a reasonable period before the last day of the company’s financial year. The fixed day must fall within 10 days before or after the last day of the financial year. The Commissioner may approve the following as a fixed day: • A fixed day, being a specific day of the week. • A fixed date, being a specific date in a calendar month. The Commissioner’s discretionary powers under section 66(13C) are not subject to objection and appeal.6 Section 9(1) of the TA Act applies similarly to the consideration (see 4.1) on the Commissioner’s discretion in the definition of “financial year” to approve other dates. 6 See section 3(4)(b) which does not include section 66(13C). The day that a company may choose to close off its financial accounts other than on the last day of the company’s financial year and within the 10 day requirement, is illustrated below: Financial year-end 10 days before 10 days after 31 January 21 – 30 January 1 – 10 February 18 – 27 February or 28 or 29 February 1 – 10 March 19 – 28 February 31 March 21 – 30 March 1 – 10 April 30 April 20 – 29 April 1 – 10 May 31 May 21 – 30 May 1 – 10 June 30 June 20 – 29 June 1 – 10 July 31 July 21 – 30 July 1 – 10 August 31 August 21 – 30 August 1 – 10 September 30 September 20 – 29 September 1 – 10 October 31 October 21 – 30 October 1 – 10 November 30 November 20 – 29 November 1 – 10 December 31 December 21 – 30 December 1 – 10 January The term “income” is defined in section 1(1) but the defined term is not used for purposes of section 66(13C).7 For the purpose of section 66(13C), “income” is interpreted as “taxable income”. This interpretation is necessary to ensure that any deductions and allowances included in the financial accounts of a company are allocated to the correct year of assessment.8 In addition, section 66(13B) provides that, for purposes of section 66(13C), income includes any aggregate capital gain or aggregate capital loss (see below). Section 66(13C)(b) provides that when financial accounts are drawn to a date after the last day of the company’s financial year, no further regard shall be had in the subsequent year of assessment to the income disclosed by those financial accounts. Similarly, a company that closes its financial accounts on a day within 10 days before the last day of its year of assessment must account for any income falling after that fixed day in the financial accounts in the subsequent year of assessment. 7 The introductory words to section 1(1) states that “unless the context otherwise indicates” the listed terms have its defined meaning. 8 For similar reasons, in CIR v Simpson 1949 (4) SA 678 (A), 16 SATC 268 at 282 Watermeyer CJ held “income” must be construed as meaning “profits or gains” which would be arrived at after deducting deductible expenditure in relation to the equivalent of section 7(2). Example 2 – Accounts accepted to a date other than the last day of a financial year Facts: Company B has a financial year-end of 31 December. As a result of many employees being on leave during the last week of December and the first few days of January, Company B applied to the Commissioner before 31 December 2024 to request approval for it to close its accounts on 5 January going forward. Result: If Company B’s application to draw up financial accounts for the extended period is approved by the Commissioner, the financial accounts for the period 1 January 2024 to 5 January 2025 will be accepted and the total amount of income disclosed by the financial accounts will be regarded as income for the 2024 year of assessment. Company B’s financial accounts for the 2025 year of assessment would be for 6 January 2025 to 5 January 2026. If Company B wants to change the fixed day approved by the Commissioner for closing its accounts back to its original closing date of 31 December, it will have to submit an application to SARS requesting the change. Example 3 – Accounts accepted to a date other than the last day of a financial year Facts: Company C has a financial year-end of 31 July. The accounting calendar used by Company C is based on 52 full weeks with the weeks commencing on a Monday and ending on a Sunday. The last day of Company C’s accounting calendar will always fall on a Sunday and for the 2024 year of assessment it will specifically fall on Sunday, 4 August 2024. Company C believes that the most meaningful and accurate comparison of sales growth can be measured on a weekly basis, from Monday to Sunday. As a result, Company C applied to the Commissioner before 31 July 2024 for approval to close its accounts on the last day of its accounting calendar, which is a Sunday. Result: The last Sunday of Company C’s accounting calendar is a fixed day that will fall within 10 days after the last day of the financial year. If Company C’s application to draw up financial accounts up until the last Sunday of its accounting calendar is approved by the Commissioner, the financial accounts for the period 1 August 2023 to 4 August 2024 will be accepted and the total amount of income disclosed by the financial accounts will be regarded as income for the 2024 year of assessment. Capital gains and capital losses (paragraphs 6 and 7 of the Eighth Schedule) Section 66(13B) provides that the word “income” in section 66(13C) includes any aggregate capital gain or aggregate capital loss. The aggregate capital gain or aggregate capital loss is determined by adding together all the capital gains and subtracting all the capital losses on all individual assets disposed of during a specific year of assessment and adding any other capital gains which are required to be taken into account.9 A company’s capital gain or capital loss is determined for a year of assessment. A capital gain will arise during a year of assessment in which an asset is disposed of if the proceeds on its disposal exceed its base cost. A capital loss will arise if the base cost of the asset exceeds the proceeds on its disposal. A capital gain or capital loss can arise during the current year of assessment on an asset disposed of in a previous year of assessment if further proceeds are received or accrued or further expenditure is incurred during the current year of assessment on that asset.10 As considered above, section 66(13C)(b) provides that no further regard shall be had in the subsequent year of assessment to the income disclosed by financial accounts drawn to a date after the last day of the company’s financial year. Section 66(13C)(b) will thus also apply to an aggregate capital gain or aggregate capital loss.11 Example 4 – Treatment of capital gains Facts: Company D has a financial year ending 30 September 2024 and is granted approval under section 66(13C) to render financial accounts for the period ending 24 September 2024. During the period 1 October 2023 to 30 September 2024 the company realised capital gains on the following assets: • 21 August 2024 – land • 26 September 2024 – shares Result: The capital gain on disposal of the land must be accounted for in the year ended 30 September 2024 (2024 year of assessment). The capital gain on disposal of the shares must be accounted for in the year ended 30 September 2025 (2025 year of assessment). 9 Paragraphs 6 and 7 of the Eighth Schedule set out the general rules for determining an aggregate capital gain or aggregate capital loss for a year of assessment. 10 Paragraphs 3 and 4 of the Eighth Schedule set out the general rules for determining a capital gain or capital loss for a year of assessment. 11 See the Comprehensive Guide to Capital Gains Tax for further consideration on an aggregate capital gain and aggregate capital loss. 4.3 Conditions for the Commissioner’s approval The following factors will be considered before the Commissioner approves an application: • The compliance status of the company.12 The company must comply with the registration requirements of all taxes,13 have no outstanding tax returns14 and no outstanding tax debts. An outstanding tax debt will not include – ➢ an amount due under an instalment payment agreement or which has been compromised under the TA Act;15 ➢ any amount that has been suspended by a senior SARS official pending an objection or appeal;16 ➢ an amount that may not be recovered for the specific period under section 164(6) that SARS receives a request for a suspension of debt or a suspension is revoked;17 or ➢ an amount below R100.18 • Rendering financial accounts to a date other than the last day of a company’s financial year-end should not have negative consequences for the fiscus (see Example 1). The earlier closure of financial accounts may lead to the manipulation of income and expenditure of the company. For example, it may result in the deferral of income derived as a result of the conclusion of a large contract or transaction. Approval will be granted only if the Commissioner is satisfied that the purpose of the application is not to obtain a tax benefit and may be subject to specified conditions. • Each application will be considered on its own merits by taking the specific circumstances of the company into account. • The application must be in writing and reasons detailing the special circumstances to be taken into account must be furnished. Supporting information and documentation must accompany the application in order for the Commissioner to make an informed decision. • The application should be submitted to a SARS service centre within a reasonable period before the last day of the company’s financial year. Failure to submit an application within a reasonable period may result in approval not being granted before the end of the financial year. Such a delay will result in the company being assessed for that year of assessment on the basis that no application was submitted. • A company that enjoyed past approval to change the day on which its financial accounts are closed, may submit a further application to change the fixed day approved by the Commissioner to another day on which it wishes to close its financial accounts in the future. The Commissioner, however, favours the 12 Section 256(3) of the TA Act provides for the requirements of a tax compliance status. 13 Registration requirements under section 22 of the TA Act. 14 The term “return” is defined in section 1 of the TA Act. A taxpayer may arrange with SARS for the submission of the outstanding return and will be considered compliant provided all the other requirements are met. 15 Section 167 or 204 of the TA Act. 16 Section 164 of the TA Act. 17 Section 164(6) of the TA Act. 18 Under section 169(4) of the TA Act, SARS need not recover a tax debt if it is less than R100. consistent reporting of results and any such application will be approved only if sound reasons exist for the requested change. • A company that wants to change the fixed day approved by the Commissioner back to its original closing date for its accounts must also submit an application to SARS requesting the change.19 4.4 Provisional tax (paragraph 23 of the Fourth Schedule) Any company, except for those excluded under the definition of “provisional taxpayer” in paragraph 1 of the Fourth Schedule, is a provisional taxpayer. Under paragraph 23 of the Fourth Schedule, a company must make its first provisional tax payment within six months as from the commencement of its year of assessment and the second provisional tax payment not later than the last day of its year of assessment. An optional additional payment (third payment) can be made within seven months of the end of the company’s year of assessment for companies with a financial year ending on the last day of February or, in any other case, within six months of the end of the year of assessment.20 This third payment will reduce the liability for any interest which may become payable for the relevant year of assessment.21 The dates by which provisional tax payments must be made remain unchanged even if a company is granted approval to submit financial accounts for a period which differs from its financial year-end. For example, a company that has been granted approval under section 66(13C) by the Commissioner to submit financial accounts to a date other than the last day of its financial year must submit its provisional tax return and make its second provisional tax payment not later than the last day of the year of assessment. The estimate should take into account the fact that accounts may be closed on a day other than the last day of the financial year. In the context of provisional tax, it is particularly important to note that if – • a day notified by SARS or specified in the Act for payment, submission or other action; or • the last day of a period within which payment, submission or other action under the Act must be made, falls on a Saturday, Sunday or public holiday, the action must be done not later than the last business day before that Saturday, Sunday or public holiday.22 19 See Example 2. 20 For more information on provisional tax, see Interpretation Note 1 “Provisional Tax Estimates”. 21 Paragraph 23A of the Fourth Schedule. 22 Section 244(1) of the TA Act. Example 5 – Provisional tax payment dates for a company that closes its accounts on a date other than the last day of a financial year Facts: Company E has a financial year-end of 31 December 2024 and is granted approval under section 66(13C) to render financial accounts for the period ending 5 January 2025. Result: Company E draws up its financial accounts for the extended period 1 January 2024 to 5 January 2025. Company E is required to make its first provisional tax payment on 28 June 2024 (30 June 2024 is a Sunday) and second provisional tax payment on 31 December 2024 even though it has been granted approval to submit financial accounts for a period which differs from its financial year-end. The provisional tax estimate should take into account the financial accounts for the period 1 January 2024 to 5 January 2025 and thus the total amount of income disclosed by the financial accounts will be regarded as income for the 2024 year of assessment. 4.5 Trading stock and livestock 4.5.1 Trading stock [section 22(6)] Trading stock held and not disposed of at the beginning and end of a year of assessment must be accounted for as specified under section 22. Section 22(6)(b) provides that any reference in section 22 to the beginning or end of a year of assessment includes a reference to the period covered by the financial accounts and accepted by the Commissioner under section 66(13C). It follows that when financial accounts are accepted by the Commissioner to a date other than the last day of the year of assessment, section 22(6)(b) requires that trading stock must be accounted for at the beginning and end of the period covered by those financial accounts. 4.5.2 Livestock [paragraph 1(a) of the First Schedule] Section 22 does not apply to farming. Paragraph 1(a) of the First Schedule contains a provision similar to section 22(6) for the purposes of determining the dates when opening and closing stock of livestock and produce on hand must be accounted for by a farmer. 4.6 Effective dates of legislation Generally, effective dates of income tax legislation take two forms, namely – • an effective date that is linked to the timing of a transaction (for example, the timing of a receipt or accrual, incurral of expenditure or disposal of an asset); or • an effective date that applies to a year of assessment. Companies applying section 66(13C) should have regard to changes in legislation that occur outside a year of assessment but within the period that the financial accounts are drawn up. The wording of the relevant effective date provision will determine how legislative changes will affect a particular transaction. As a result, it is not possible to lay down definite rules for dealing with such changes. Effective dates applicable to a transaction date are unaffected by the fact that the results for the period that the financial accounts are drawn up are taken back to an earlier year of assessment or carried forward to a future year of assessment. Example 6 – Change in legislation applicable to a transaction date Facts: Company F has a financial year ending on 30 June. It is granted approval under section 66(13C) to render financial accounts up until 5 July 2024. On 3 July 2024, Company F incurred an expense in relation to its trade. The section governing the deductibility of the expense was withdrawn with effect from 30 June 2024 and applied to any expenditure incurred on or after that date. Result: The expenditure will not be deductible because the transaction took place after the effective date of the amendment (30 June 2024) which applies to all transactions on or after that date. An effective date that applies to a year of assessment can, however, apply to a transaction conducted before or after the year of assessment if it falls within the period that the financial accounts are drawn up and the results for that period are carried forward or back to the year of assessment in question. Example 7 – Change in legislation applicable to a year of assessment Facts: Company G has a financial year ending on 31 December. It is granted approval under section 66(13C) to render financial accounts up until 8 January 2025. On 5 January 2025 Company G received income in relation to its trade. The section governing the exemption of that income from normal tax was inserted with effect from 1 January 2025 and applicable to years of assessment commencing on or after that date. Result: Under section 66(13C) the income received must be accounted for in the year of assessment ending 31 December 2024. The income will not be exempt from normal tax because the amendment applies to years of assessment commencing on or after 1 January 2025. The income earned on 5 January 2025 is included in Company G’s year of assessment ending on 31 December 2024 which commenced on 1 January 2024. 5. Tax period for value-added tax A company registered or required to be registered as a vendor23 is allocated a specific tax period for which the output tax and input tax is declared and the difference between them is calculated and either paid to or refunded by SARS for that specific tax period. The closure by a company of its financial accounts on a day other than the last day of its financial year will not have any impact on its VAT liability for any tax period. A vendor is required to submit VAT 201 returns and account for VAT to SARS according to the tax periods allocated to the vendor by the Commissioner. However, paragraph (ii) of the proviso to section 27(6) of the VAT Act 89 of 1991provides for the Commissioner to allow a tax period to end on a fixed day instead of the last day of the month. The fixed day must fall within 10 days before or after the last day of a month and the future tax period approved by the Commissioner must be used by the vendor for a minimum period of 12 months from the commencement of the first tax period for which the change is made. For more information on the different tax periods, see Interpretation Note 52 “Approval to End a Tax Period on a Day other than the Last Day of a Month”. 6. Conclusion A company intending to close its financial accounts either within 10 days before or after the end of a year of assessment must submit an application to a SARS service centre for approval to draw up financial accounts to a closing date other than the end of its financial year. Section 66(13C) relates only to a situation in which a company obtains approval from the Commissioner to close its accounts on a date other than the last day of its financial year. This approval does not result in a change in the company’s financial year-end and therefore does not change its year of assessment.
