How to File BIR Form 1604-E and the Annual Alphalist

What BIR Form 1604-E Covers and Who Must File It

BIR Form 1604-E is the Annual Information Return of Creditable Income Taxes Withheld (Expanded). It is the year-end summary that every withholding agent files to report all expanded withholding tax (EWT) deducted from suppliers, contractors, lessors, professionals, and other payees during the calendar year. It is separate from Form 1604-C, which covers compensation withheld from employees, and Form 1604-F, which covers final withholding taxes.

You are required to file 1604-E if the Bureau of Internal Revenue (BIR) has designated your business as a withholding agent for EWT. This typically includes corporations, government agencies and instrumentalities, and individuals engaged in business who are required under Revenue Regulations No. 2-98 (as amended) to withhold tax on specific income payments such as rent, professional or talent fees, commissions, contractor's fees, and payments to top withholding agents (TWAs). If your business regularly withholds EWT and remits it through BIR Form 0619-E monthly and Form 1601-EQ quarterly, you are almost certainly required to file 1604-E at year-end.

Even businesses that only occasionally make payments subject to EWT should confirm their status with their Revenue District Office (RDO), because failing to file when required creates an "open case" that can trigger penalties and complicate future BIR transactions such as tax clearance requests.

Understanding the Annual Alphalist of Payees

The Alphalist of Payees Subjected to Expanded Withholding Tax is filed together with Form 1604-E. It is a detailed, payee-by-payee listing showing each supplier's name, Tax Identification Number (TIN), the Alphanumeric Tax Code (ATC) that identifies the type of income payment, the total income payments made for the year, and the total tax withheld. In effect, the alphalist is the supporting schedule that proves the totals declared in Form 1604-E, and it must reconcile with the amounts you already reported in your quarterly 1601-EQ filings and the BIR Form 2307 certificates you issued to each payee.

Because the alphalist can run to hundreds of line items for a mid-sized business, the BIR does not accept it as a plain attachment. It must be prepared using the BIR's Alphalist Data Entry and Validation Module (downloadable from the BIR website), which converts your payee data into a structured .DAT file. This file is then submitted electronically, either through the BIR's eSubmission facility or as an attachment when filing through eFPS, depending on your taxpayer classification. Always download the current version of the module before year-end, since the BIR periodically updates the validation rules and file format.

Step-by-Step: Preparing and Filing 1604-E and the Alphalist

Consider a company that leases office space for ₱100,000 per month. Rental payments fall under ATC WC100 with a 5% EWT rate, so the company withholds ₱5,000 every month and pays the lessor the net amount, issuing a Form 2307 each quarter. Over the year, total rental payments reach ₱1,200,000 and total EWT withheld reaches ₱60,000. This single payee produces one line in the alphalist showing gross payments of ₱1,200,000 and tax withheld of ₱60,000, which must match the sum of the four 1601-EQ filings for that payee's ATC code. A business with fifty or a hundred such suppliers will have that many lines, all needing to tie out before submission.

In Kontabler, every expanded withholding tax transaction recorded during the year — the ATC code, payee TIN, gross amount, and tax withheld — is captured automatically at the point of posting each disbursement, so the annual alphalist is generated in a ready-to-validate format instead of being manually rebuilt from spreadsheets and quarterly returns at year-end.

Once the alphalist is validated and the DAT file is generated, file Form 1604-E itself through eBIRForms or eFPS, whichever platform applies to your taxpayer classification, and keep the system-generated confirmation together with the alphalist submission acknowledgment as proof of filing.

Deadlines and Penalties

Under the TRAIN Law amendments to Section 58 of the Tax Code, Form 1604-E and its accompanying alphalist are due on or before March 1 of the year following the calendar year in which the income payments and withholding took place. This is later than the January 31 deadline for Forms 1604-C and 1604-F, so accountants handling both should track the two deadlines separately. For calendar year 2025, the 1604-E and alphalist are therefore due on or before March 1, 2026. Because these dates can shift when the deadline falls on a weekend or holiday, or if the BIR issues a specific circular extending the period, always confirm the exact due date on the BIR website close to filing season.

Late or incorrect filing carries two layers of exposure. First, if any related EWT liability remains unpaid, the standard penalties under Sections 248 and 249 of the Tax Code apply: a 25% surcharge on the basic tax due, plus 12% annual interest computed from the original deadline until full payment. Second, under Section 250, failure to file a correct and complete information return such as the alphalist carries a separate penalty of ₱1,000 for each failure, capped at ₱25,000 for all such failures within a calendar year. Beyond these statutory penalties, if the BIR determines that EWT on a particular expense was not properly withheld or remitted, that expense can be disallowed as a deductible business expense under Section 34(K), which increases your income tax liability on top of the withholding tax penalties.

Note that the Ease of Paying Taxes (EOPT) Act of 2024 removed the ₱500 annual registration fee and simplified several administrative and invoicing requirements, but it did not change the obligation of registered withholding agents to file Form 1604-E and the annual alphalist. Businesses should also keep an eye on annually adjusted figures, such as VAT registration thresholds and any updated EWT rates under future regulations, since these are set by the BIR and can change from year to year.

Common Errors That Delay or Reject Filings

The most frequent reason an alphalist gets rejected or flagged is a mismatched or invalid TIN — either a typo, a TIN registered under a different name, or a payee who has since changed registration details. The second most common issue is using the wrong ATC code, which misclassifies the nature of the income payment and can cause discrepancies when the BIR cross-references your 1604-E against the 1601-EQ filings and the 2307 certificates your payees themselves report as creditable withholding tax. A third recurring problem is simple arithmetic mismatch: the yearly totals in the alphalist not tying out with the sum of the four quarterly remittance returns, often because a mid-year correction or amended return was never reflected in the year-end summary.

To avoid these issues, reconcile EWT records quarterly rather than waiting until year-end, keep payee TINs and registered names updated throughout the year, and run the BIR's validation module well before the March 1 deadline so there is time to correct errors and resubmit if needed.

Reconciling your quarterly 1601-EQ filings against your books every quarter, rather than only at year-end, is the single most effective habit for avoiding a rejected alphalist.
