Conversely, if the transaction is fictitious, canceled, or incorrectly recorded, the business must adjust the accounting figures according to the nature and period in which it occurred.<\/p>\n<section>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_85 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p

If the transaction is genuine and the expense is recorded correctly according to accounting principles, the non-deductibility for corporate income tax purposes is usually handled on the tax return. Adjustments to the accounting records are only necessary when the transaction is fictitious, cancelled, incorrectly recorded, or involves other accounting errors.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Thue_GTGT_dau_vao_khong_duoc_khau_tru_hach_toan_the_nao\"><\/span>How should non-deductible input VAT be accounted for?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The non-deductible tax portion needs to be adjusted from the deductible VAT and treated according to the nature of the purchase. This amount may affect expenses, inventory, cost of goods sold, tools and equipment, or the original cost of assets.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Hoa_don_rui_ro_co_phai_loai_ngay_khong\"><\/span>Should risky invoices be discarded immediately?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Businesses should not rely solely on warnings to immediately discontinue a purchase. They need to verify the supplier&#039;s status, contracts, delivery, acceptance, payment, and the use of goods or services, and then proceed based on the relevant records and specific circumstances.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Nen_treo_hay_loai_hoa_don_rui_ro\"><\/span>Should you keep or discard high-risk invoices?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>There is no general rule that every risk invoice must be held in a specific account. Businesses need to determine whether the transaction has occurred, whether the payment obligation has been formed, and what documentation is missing. While the transaction status can be tracked separately, the journal entry must still accurately reflect the nature of the transaction.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Chi_phi_bi_loai_sau_quyet_toan_co_phai_dieu_chinh_bao_cao_tai_chinh_khong\"><\/span>Do expenses disallowed after final settlement require adjustments to the financial statements?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Adjusting financial statements is not always necessary. If an expense is correctly recorded in accounting but not tax-deductible, the business typically handles the difference on its tax return. Financial statements only need adjustment when a transaction or accounting data has been incorrectly recorded.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Hoa_don_nhieu_nam_truoc_bi_loai_co_phai_dieu_chinh_hoi_to_khong\"><\/span>Do invoices from many years ago that were disallowed need to be adjusted retrospectively?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This depends on the nature and materiality of the error. If only a tax difference arises, the business may only need to adjust the tax records. If the transaction or accounting figures from the previous period are incorrect, the business needs to assess the adjustment according to the applicable accounting system.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Hoa_don_cua_doanh_nghiep_bo_tron_co_duoc_tinh_chi_phi_khong\"><\/span>Can invoices from a business that has absconded be considered as expenses?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>It is impossible to draw conclusions based solely on the supplier&#039;s current status. It is necessary to determine the transaction date, prove the authenticity of the goods or services, examine records and cash flow, and comply with tax authority requirements.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Hoa_don_sai_sot_co_phai_la_hoa_don_bi_loai_khong\"><\/span>Are invoices with errors considered invalid invoices?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Not all erroneous invoices are rejected. Many errors can be addressed through corrections or replacements as per regulations. The tax and accounting consequences depend on the type of error, when it is discovered, and whether the transaction was genuine.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"VAT_khong_duoc_khau_tru_co_duoc_tinh_vao_chi_phi_khong\"><\/span>Can non-deductible VAT be included in the expenses?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The non-deductible VAT portion can be treated as an expense, inventory value, cost of goods sold, or asset cost depending on the nature of the purchase and applicable conditions. It should not be automatically included in a single expense account.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Hoa_don_tu_5_trieu_dong_thanh_toan_tien_mat_co_duoc_khau_tru_thue_GTGT_khong\"><\/span>Are VAT deductible for invoices of 5 million VND or more paid in cash?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>For transactions subject to regulations effective from July 1, 2025, goods or services purchased worth VND 5 million or more, including VAT, require non-cash payment documentation to qualify for deduction, except in cases specifically stipulated.<\/p>\n<\/section>\n<h2><span class=\"ez-toc-section\" id=\"Ket_luan\"><\/span>Conclude<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Accounting for rejected invoices should begin with identifying the true nature of the problem, not with immediately selecting an account or journal entry.<\/p>\n<p>Accountants need to clearly distinguish between:<\/p>\n<ul>\n<li>Is the transaction real or not?.<\/li>\n<li>Is input VAT eligible for deduction?.<\/li>\n<li>Is the expense eligible for deduction when calculating corporate income tax?.<\/li>\n<li>Is the invoice only under warning or has a decision already been made?.<\/li>\n<li>Does the issue belong to the current period or the previous period?.<\/li>\n<\/ul>\n<p>When a transaction is real, accounting expenses and tax-deductible expenses may differ. When a transaction is fictitious, cancelled, or incorrectly recorded, the business must adjust its accounting records according to the nature and period of the transaction.<\/p>\n<p>A process for controlling invoices, documents, and exceptions before payment, declaration, and accounting helps businesses reduce reprocessing time, prepare better explanatory documents, and limit future tax risks.<\/p>\n<p>Businesses need to discuss possible invoice processing procedures. <a href=\"https:\/\/bizzi.vn\/dang-ky-dung-thu\/\">Register for a consultation on Bizz solutions.<\/a>.<\/p>\n<p><em><small>This content provides general guidance and does not replace a specific assessment of the case.
