transaction occurs.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Regarding the exchange rate for recording expenses: In cases where the exchange rate stated on the export invoice is used to record expenses incurred in foreign currency, it should be the selling rate of the commercial bank where the business expects to conduct the transaction at the time the transaction occurs.<\/span><\/li>\n<\/ul>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Thuc_trang_ap_dung_ty_gia_mua_ngan_hang_chi_dinh\"><\/span><b>Current

A prerequisite for applying the approximate exchange rate is that its use must ensure that it does not materially affect the financial statements of the business in the accounting period.<\/span><\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Therefore, under the new regulations, the exchange rate for export invoices in 2026 is no longer limited solely to the pure transfer buying rate at the designated payment bank. Accountants are now allowed to use the average transfer buying and selling rate or an approximate rate within the permitted range.\u00a0<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">In summary, the export invoice exchange rate for 2026, according to Circular 99\/2025\/TT-BTC, is the average buying and selling rate for transfers or an approximate difference not exceeding -1% to 1% compared to the average buying and selling rate for transfers.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Quy_dinh_ve_ty_gia_ghi_so_hach_toan_ngoai_te\"><\/span><b>Regulations on the exchange rate for foreign currency accounting<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">In parallel with the actual exchange rate used for initial conversion when determining the exchange rate for export invoices, Circular 99\/2025\/TT-BTC also clarifies the concept and method of applying the book exchange rate.

A bank with which the company frequently conducts transactions should be chosen as the basis for obtaining the average exchange rate. This regulation must be applied consistently throughout the entire fiscal year.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Strictly control the range of -1% to 1%: If the business chooses to use an approximate exchange rate as the export invoice rate, the internal control department must set up an automatic formula in the accounting software to check the daily deviation, ensuring that it does not exceed the regulated threshold of 1% compared to the average buying and selling exchange rate of the chosen bank.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Assessing Materiality in Financial Statements: In cases of significant exchange rate fluctuations during the year, the misuse of approximate exchange rates can considerably distort actual export revenue. The chief accountant needs to periodically reassess the extent of this impact to adjust the exchange rate calculation method accordingly, avoiding the risk of tax authorities rejecting or requiring conversion adjustments during audits.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Ensuring the quality of accounting management personnel: New regulations emphasize accountability and consistency in financial policies.

If a business mistakenly uses the accounting exchange rate to prepare invoices or customs declarations (or vice versa), the data on electronic invoices, customs declarations, and accounting records will not match, potentially leading to the risk of being required to explain, adjust, or collect back taxes from tax and customs authorities.

From now on, business managers and chief accountants need to proactively update software, train personnel, and prepare optimal foreign exchange accounting scenarios in accordance with Circular 99\/2025\/TT-BTC to ensure a safe and efficient financial year in 2026.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">To completely alleviate these pressures and risks, businesses in industrial parks and high-tech zones can choose to partner with specialized suppliers.<\/span><strong><span style=\"color: #0000ff;\"><a style=\"color: #0000ff;\" href=\"https:\/\/ketoan.man.net.vn\/en\/dich-vu-ke-toan-tphcm\/\"> accounting services<\/a><\/span><\/strong><span style=\"font-weight: 400;\"> Reputable, professional, and experienced partners provide support and partnership to maximize benefits and avoid potential risks.<\/span><\/p>\n<p style=\"text-align: justify;\"><a href=\"https:\/\/ketoan.man.net.vn\/en\/lien-he\/\"><span style=\"font-weight: 400;\"><strong><span style=\"color: #0000ff;\">Contact MAN \u2013 Master Accountant Network<\/span><\/strong><\/span><\/a><span style=\"font-weight: 400;\"> For prompt support and free advice!<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Thong_tin_lien_he_MAN_%E2%80%93_Master_Accountant_Network\"><\/span><b>Contact information MAN \u2013 Master Accountant Network<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li><b>Address:<\/b><span style=\"font-weight: 400;\"> No. 19A, Street 43, Tan Thuan Ward, Ho Chi Minh City<\/span><\/li>\n<li><b>Mobile\/Zalo:<\/b><span style=\"font-weight: 400;\"> 0903 963 163 \u2013 0903 428 622<\/span><\/li>\n<li><b>E-mail:<\/b><span style=\"font-weight: 400;\"> man@man.net.vn<\/span><\/li>\n<li><b>Google Business Profile:<\/b> <a href=\"https:\/\/share.google\/EmihzHg354pCASC9k\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\"><strong><span style=\"color: #0000ff;\">View MAN \u2013 Master Accountant Network&#039;s Google Business Profile<\/span><\/strong>\u00a0<\/span><\/a><\/li>\n<li><b>LinkedIn Founder:<\/b><strong><span style=\"color: #0000ff;\"> <a style=\"color: #0000ff;\" href=\"https:\/\/www.linkedin.com\/in\/tuy%C3%AAn-l%C3%AA-ho%C3%A0ng-65292aa0\/\" target=\"_blank\" rel=\"noopener\">View expert Le Hoang Tuyen&#039;s LinkedIn profile.\u00a0<\/a><\/span><\/strong><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Responsible for production and professional content review by: Mr. <\/span><strong><span style=\"color: #0000ff;\"><a style=\"color: #0000ff;\" href=\"https:\/\/man.net.vn\/le-hoang-tuyen\/\" target=\"_blank\" rel=\"noopener\">Le Hoang Tuyen \u2013 Founder &amp; CEO of MAN \u2013 Master Accountant Network<\/a><\/span><\/strong><span style=\"font-weight: 400;\">He is a CPA Vietnam auditor with over 30 years of in-depth experience in accounting, auditing, taxation, and corporate legal consulting.<\/span><\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Giai_dap_thac_mac_ve_ty_gia_xuat_hoa_don_xuat_khau_cho_doanh_nghiep_san_xuat\"><\/span><b>Answering questions about exchange rates for export invoices for manufacturing businesses.<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Doanh_nghiep_san_xuat_xuat_khau_mo_nhieu_tai_khoan_ngoai_te_thi_xac_dinh_nhu_the_nao_de_lay_ty_gia_xuat_hoa_don_xuat_khau\"><\/span><b>If an export-oriented manufacturing company opens multiple foreign currency accounts, how does it determine the exchange rate for issuing export invoices?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">According to Circular 99\/2025\/TT-BTC, businesses are not required to choose only one bank, but it must be a commercial bank where they regularly conduct transactions. <\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Thoi_diem_thong_quan_to_khai_hai_quan_khac_voi_thoi_diem_xuat_hoa_don_dien_tu_xuat_khau_doanh_nghiep_san_xuat_ap_dung_ty_gia_nao_de_ghi_nhan_doanh_thu_va_ty_gia_xuat_hoa_don_xuat_khau\"><\/span><b>Since the time of customs clearance is different from the time of issuing the electronic export invoice, which exchange rate should manufacturing businesses use to record revenue and which exchange rate should they use for issuing export invoices?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Accountants need to clearly distinguish between two types of exchange rates serving different purposes. The exchange rate on the customs declaration is the rate published by the General Department of Customs on the date of registration. This rate is only valid for calculating export and import taxes and for customs clearance procedures; it is not used for accounting entries. The exchange rate on the export invoice and for recording accounting revenue is the average buying and selling rate of the commercial bank frequently used on the invoice date. Accounting revenue must be consistent with the converted value on this invoice.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Doanh_nghiep_san_xuat_xuat_khau_theo_loai_hinh_gia_cong_cho_thuong_nhan_nuoc_ngoai_hach_toan_hoa_don_phi_gia_cong_bang_ngoai_te_the_nao\"><\/span><b>How should businesses that manufacture and export goods under a processing contract for foreign traders account for processing fees in foreign currency?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">For export processing, the nature of the enterprise&#039;s revenue is revenue from providing processing services. The exchange rate for processing fees on export invoices will follow the general regulations of Circular 99, which is to use the average buying and selling exchange rate for transfers or the approximate exchange rate of the bank where the enterprise designates the foreign partner to pay the processing fee on the date the processing service invoice is completed.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Ap_dung_sai_ty_gia_xuat_hoa_don_xuat_khau_co_anh_huong_gi_khong\"><\/span><b>What are the consequences of using the wrong exchange rate on export invoices?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Incorrect exchange rate application, for example using the accounting exchange rate to prepare invoices or customs declarations instead of the tax exchange rate stipulated by customs law, can lead to inconsistencies in data on electronic invoices, customs declarations, and accounting records.
