Last week, Wang, an accountant in Hangzhou, was helping a cross-border e-commerce company file its Q2 2026 tax return when he noticed that the interface of the new version of the Electronic Tax Bureau had completely changed—the left-hand menu had been cut in half, a new ”Red-Letter Confirmation Form” module had been added, and there were more than 20 additional fields on the tax return form. He stared at the screen in bewilderment for half an hour: ”Is this an upgrade or a whole new system?”

Starting in July 2026, the National Electronic Tax Bureau will be uniformly upgraded to the new ”Smart Tax” version, and the three major filing modules—Value-Added Tax, Corporate Income Tax, and Individual Income Tax—will all be completely redesigned. This article provides a comprehensive overview of the new interface, new processes, and common pitfalls, so that after reading it, you’ll be ready to start filing your taxes.

01

What Has Actually Changed in the New Version of the Electronic Tax Bureau?

Three Major Changes in the New Version of the Electronic Tax Bureau (v5.0) in July 2026:

First.User Interface Redesign. The system has been reorganized from ”modules by tax type” to ”modules by business process.” The left-hand menu now consists of four main sections: ”My Taxes and Fees,” ”File My Return,” ”Invoice Management,” and ”Risk Alerts.” The path to access the filing portal has been shortened from a three-step process (”Menu → Tax Type → Tax Return”) to a two-step process (”My Taxes and Fees → One-Click Filing”).

Second.Automatic Data Pre-fill. The new system is integrated with the "Golden Tax Phase IV" big data platform, so data such as a company's invoice issuance records, input tax credits, bank transaction histories, and employee social security information will be automatically pre-filled into the tax return forms. Accountants only need to verify the information; manual data entry is no longer required.

Third.Intelligent Risk Control. The new system adds three major features: ”Red-Letter Confirmation Forms,” ”Risk Alerts,” and ”Tax Self-Audits.” Previously, red-letter invoices on VAT return forms required the circulation of paper documents; now, the Electronic Tax Bureau generates them automatically. Previously, taxpayers had to wait for the tax authority to audit their accounts to discover potential risks; now, the system alerts them to anomalies in advance during the filing process.

For accountants, these three changes,The filing time has been reduced from 3–5 days to 1–2 days....but the requirements for ”declaration quality” have become stricter—because if the data pre-filled by the system is incorrect and the accountant submits it without noticing the error, the system will automatically flag it as a ”false declaration.”

VAT Filing: A 5-Step Process

Standard Procedure for the 2026 VAT Filing (Monthly Filing for General Taxpayers):

Step 1,Log in to the new version of the Electronic Tax Bureau, go to the ”My Taxes” page. This page will automatically display a list of the tax types your business needs to file this month, along with their filing deadlines. Click the ”VAT Filing” button to proceed.

Step 2,The system automatically pre-fills the tax return form. The new tax return form automatically retrieves data from the following five sources: sales invoices (invoices issued by your company), purchase invoices (invoices received by your company), customs duty payment certificates, export tax rebate data, and agricultural product purchase invoices. Data from all five sources is pre-filled into the corresponding fields on the tax return form.

Step 3,Accounting Reconciliation + Correction. Key points to verify: Are all output tax amounts accounted for (are there any unreported, uninvoiced revenues)? Are input tax amounts compliant (are there any unaccounted-for or delayed invoices)? Is the export tax refund amount accurate?

Step 4,Processing Red-Letter Confirmation Slips. If there are credit invoices (returns, discounts, or adjustments) during the month, the new system will automatically generate a ”Credit Confirmation Form,” which the accountant must confirm online and match with the corresponding debit invoice.

Step 5,Submit the Declaration + Make the Payment. After confirming that everything is correct, click ”Submit Declaration,” and the system will automatically calculate the tax due. If tax is due, you can pay it directly online (by linking a corporate bank account or using a third-party payment service).

The entire process takes 5–10 minutes,An order of magnitude faster than the previous 2–3 hours. However, this is only true if you have properly managed your invoices, verified input tax credits, and filed export tax refund claims from the outset; otherwise, the data pre-filled by the system will be incorrect.

Corporate Income Tax: A Dual-Track System of Quarterly Filing and Annual Settlement

There are two types of corporate income tax returns:Quarterly Advance Payment(within 15 days after the end of each quarter) andAnnual remittance(by May 31 of the following year).

New Changes to Advance Payments for Q3 2026 (July–September):

First.New Advance Payment Return Form A200000. Starting in Q3 2026, the corporate income tax advance payment return form will be revised. The new form includes additional sections such as ”Additional Deduction for R&D Expenses,” ”Tax Relief for Small and Low-Profit Enterprises,” and ”Preferential Treatment for High-Tech Enterprises,” and the unit of measurement for amounts will change from ”yuan” to ”10,000 yuan.”

Second.Automatic Matching of Eligibility for Tax Incentives. The new system will automatically determine whether a company qualifies for preferential treatment as a small or low-profit enterprise (annual taxable income ≤ 3 million, number of employees ≤ 300, total assets ≤ 50 million) or a high-tech enterprise; if eligible, the tax return will automatically include the applicable tax reductions or exemptions.

Third.Automatic Calculation of Cross-Quarter Loss Offsets. If a company has losses carried forward from previous years, the new system will automatically calculate the current taxable income in accordance with the ”carryback of pre-tax losses within 5 years” rule, without requiring manual entry by the accountant.

Regarding annual tax settlement, the deadline for the 2026 corporate income tax annual settlement remains May 31 of the following year; however, the number of forms required has been reduced from 13 to 8 (”main form + 7 supplementary forms”), resulting in a reduction in the reporting workload of approximately 40%.

但The audit rate for the 2026 annual tax settlement has increased by 15%.In particular, the three major industries—cross-border e-commerce, platform live streamers, and construction labor services—have been designated as key targets for audits. It is recommended that companies in these industries conduct a ”self-inspection” before filing their annual tax returns to avoid triggering system alerts that could lead to manual audits.

Individual Income Tax: Reporting Business Income Is a Key Focus

For e-commerce sellers,The focus of the 2026 individual income tax filing is ”business income”The

In the past, many e-commerce business owners paid themselves through ”wages and salaries,” filing monthly individual income tax returns and conducting year-end tax settlements. However, starting in 2026, the tax authorities will automatically issue alerts for accounts with ”business-to-personal” transactions exceeding 200,000 per month, indicating that ”there may be underpayment of individual income tax.”

The correct approach is: E-commerce companies should report profit distributions under ”Business Income” (5%-35%, excess progressive tax rate), not under ”Wages and Salaries” (3%-45%, progressive tax rate).

An example:

Method 1,Wages and Salaries: The boss earns a monthly salary of 20,000 and an annual salary of 240,000. The individual income tax payable = (240,000 - 60,000) × 10% - 2,520 = 12,780 yuan.

Method 2,Business Income (Dividends): The company’s annual profit is 1 million. First, 25% in corporate income tax is paid, totaling 250,000; the remaining 750,000 is distributed as dividends to the owner. The owner reports this as ”business income”; the individual income tax payable = 750,000 × 20% – 10,500 = 139,500 yuan.

Option 2 seems to involve paying more, but if you take into account a range of factors—such as the company’s profit margin, year-end bonuses, and special additional deductions—E-commerce business owners with annual revenues exceeding 1 million can save 200,000–300,000 in taxes compared to salaried employees by combining business income with compliant individual income tax planning.The

In 2026, the new electronic tax bureau significantly simplified the filing process for ”business income”: it automatically retrieves the amount of distributable profits from the enterprise’s annual tax settlement data, so business owners only need to confirm the dividend amount and deductions.

5 Common Pitfalls: 90% Newcomers Fall Into the First and Second Ones

The 5 Most Common Pitfalls When Filing Taxes via the New Version of the Electronic Tax Bureau in 2026:

The first pitfall,Submitted without verifying the pre-filled data. The output tax amount pre-filled by the system is automatically calculated based on ”invoice amount + tax rate.” However, if you have ”unbilled revenue” (such as cash receipts or platform commission income), you must manually enter it in the ”Unbilled Revenue” field; otherwise, it will be deemed ”underreported revenue.”

The second pitfall,Input invoices were not marked for verification. Although the new system can automatically pre-fill input tax, this is only possible if the invoices have already undergone ”selection and verification.” If a supplier issues an invoice and you do not select it in a timely manner, the input tax will be underreported during filing, resulting in an overpayment of taxes.

The third pitfall,The red-letter confirmation slip was not processed in a timely manner. If there are returns in a given month but credit invoices are not issued in a timely manner, the new system will display a message stating ”The credit invoices and debit invoices do not match” during the filing process, and the filing will be blocked. We recommend completing the credit invoice processing for all returns by the 25th of each month.

The fourth pitfall,Zero-reporting is under close scrutiny. The new version of the Electronic Tax Bureau automatically flags businesses that have filed zero tax returns for three consecutive months as ”under close scrutiny,” and the tax authority will send them a notice to conduct a self-inspection. If a business is truly not operating, it is recommended that it follow the ”suspension of business registration” process rather than simply filing zero tax returns.

The fifth pitfall,Failure to Pay Timely Attention to Risk Alerts. The new version of the Electronic Tax Bureau includes a ”Risk Alerts” module, which displays ”This Company’s Risk Points for This Month” (such as abnormal input tax, an unusually low tax burden ratio, or abnormal related-party transactions) before each filing. Accountants must first review the risk alerts and confirm that everything is correct before proceeding with the filing process.

The 2026 Electronic Tax Bureau is not simply a ”system upgrade,” but rather“Full Implementation of ”Data-Driven Tax Administration”. For small and medium-sized enterprises, the biggest change isn’t that the processes have changed, but that there’s no longer any room to ”operate in the dark”—every piece of revenue, every invoice, and every transaction is under the scrutiny of the Golden Tax Phase IV system.

Compliance reporting is not just about preparing for audits, but ratherNip Tax Risks in the BudThe
