BIR RR No. 4-2026: One-Time Tax Abatement Guide for Micro Taxpayers

Executive Summary

The Bureau of Internal Revenue has issued Revenue Regulations No. 4-2026 to give qualified micro taxpayers a one-time opportunity to settle certain tax liabilities, penalties, and open cases through abatement.

For small businesses, professionals, freelancers, online sellers, and micro enterprises, this is an important development. Many taxpayers accumulate BIR liabilities not because they intentionally avoid taxes, but because they miss filings, stop operations without proper closure, fail to respond to assessments, or do not understand the consequences of open tax cases.

RR No. 4-2026 provides a limited remedy. It allows qualified micro taxpayers to apply for abatement of taxes and/or penalties, including surcharge and interest, for covered delinquent accounts, assessments, and stop-filer cases.

The regulation applies to micro taxpayers whose gross sales for the year are less than ₱3,000,000. It covers certain tax cases as of December 31, 2025, provided the basic tax and/or penalties do not exceed ₱80,000 for a taxable year.

The taxpayer must manually file an application with the Revenue District Office that has jurisdiction over the taxpayer. Once the application is accepted, the taxpayer must pay a ₱5,000 abatement fee using BIR Form No. 0605 and submit proof of payment within the required period.

Qualified taxpayers may avail of the benefit until December 31, 2026, unless the period is extended.

The key point is simple: this is a chance for qualified micro taxpayers to clean up old tax issues, but it is not automatic. The taxpayer must apply properly, meet the conditions, pay on time, and complete the required process.

What Is BIR RR No. 4-2026?

BIR Revenue Regulations No. 4-2026 prescribes the guidelines and procedures for the availment of a one-time abatement of taxes and/or penalties for micro taxpayers.

The regulation was issued under the authority of the Tax Code, particularly Sections 244 and 245 in relation to Section 204(B), which allows the Commissioner of Internal Revenue to abate or cancel tax liabilities in certain cases.

In plain language, abatement means the BIR may reduce, cancel, or settle certain taxes, surcharge, interest, or penalties under the conditions stated in the regulation.

This is especially helpful for micro taxpayers who have old tax issues, pending assessments, delinquent accounts, or open stop-filer cases. It also covers micro taxpayers who have already stopped doing business but still have unresolved BIR cases.

For many small taxpayers, these open cases can become a barrier to closure, tax clearance, registration updates, or future business activity.

Why This Regulation Matters

Micro taxpayers often face practical compliance challenges.

Some small businesses stop operating but never formally close their BIR registration.

Some taxpayers fail to file returns because they had no sales, not realizing that non-filing can still create open cases. Others receive BIR notices but do not respond because the process feels intimidating or confusing.

Over time, these issues can grow into penalties, interest, assessments, or stop-filer cases.

RR No. 4-2026 gives qualified taxpayers a structured way to resolve covered tax issues through a one-time abatement program. This can help taxpayers regularize their status, reduce compliance risks, and move forward without unresolved BIR cases.

However, taxpayers should understand that this is not a blanket tax amnesty. It has qualifications, thresholds, deadlines, and procedural requirements.

Who Is Considered a Micro Taxpayer?

Under RR No. 4-2026, a micro taxpayer refers to a taxpayer whose gross sales for the year are less than ₱3,000,000.

For mixed income earners, gross sales cover only business income. Compensation income earned under an employer-employee relationship is excluded.

This distinction matters.

For example, an individual who is both an employee and a small online seller should look only at the business income when determining whether the taxpayer qualifies as a micro taxpayer for purposes of the regulation.

The taxpayer may be a natural person, juridical entity, or duly authorized representative, as long as the taxpayer is classified as a micro taxpayer and meets the requirements of the regulation.

What Cases Are Covered by the One-Time Abatement?

RR No. 4-2026 applies to covered tax issues existing as of December 31, 2025.

The regulation covers delinquent accounts, assessments whether preliminary or final, disputed or not, and open stop-filer cases. It also includes cases involving micro taxpayers who have ceased business operations.

A delinquent account generally refers to tax due on or before December 31, 2025 from a taxpayer who failed to pay within the prescribed period. It may arise from a self-assessed tax or from a deficiency assessment that has become final and executory.

An assessment may be preliminary or final, disputed or not, as long as it was issued on or before December 31, 2025 and has not yet become final and executory.

A stop-filer case refers to a case where a registered taxpayer failed to file or submit the required tax return or tax information within the prescribed deadline.

For small taxpayers, stop-filer cases are common. They often arise when a taxpayer fails to file returns even for periods with no business activity.

What Is the ₱80,000 Threshold?

The regulation applies to cases of micro taxpayers with delinquent or assessed basic tax and/or penalties of not more than ₱80,000.

The ₱80,000 threshold refers to the total basic tax liabilities and/or penalties arising from violations of the Tax Code covering the relevant cases for a taxable year.

This means taxpayers should not review each case in isolation without checking the total amount for the taxable year.

If the total amount exceeds the threshold, the taxpayer may not qualify under the simplified abatement coverage provided by RR No. 4-2026.

This is why a taxpayer should first request or review records of open cases, assessments, delinquent accounts, and penalties before applying.

What Specific Cases May Be Applied for Abatement?

RR No. 4-2026 lists several types of cases that may be covered, provided the taxpayer is a qualified micro taxpayer and the threshold requirement is met.

These include delinquent accounts, cases with administrative protest pending before BIR offices, tax cases disputed before the Department of Justice or courts, tax collection cases filed in court, pending compromise settlement requests, pending abatement requests under prior rules, certain criminal violations not yet filed in court, accounts payable or due to BIR recorded in the taxpayer’s books, and cases where there is no basic tax due but penalties are involved.

The regulation also includes open stop-filer cases as of December 31, 2025.

This wide coverage is important because many micro taxpayers do not have only one type of BIR issue. A taxpayer may have both non-filing penalties and an old assessment. Another may have ceased operations but still has open returns or unpaid liabilities.

The abatement program is designed to help qualified taxpayers settle covered cases more efficiently.

Who May Avail of the Abatement?

A qualified micro taxpayer may avail of the abatement personally or through a duly authorized representative.

This includes natural persons, businesses, and juridical entities classified as micro taxpayers.

The regulation also expressly includes micro taxpayers who have ceased business operations. This is important because many taxpayers who stopped operating still remain registered with the BIR and may continue to have open cases.

However, any payments already made by micro taxpayers on covered cases before the effectivity of RR No. 4-2026 are not refundable.

This means the regulation provides a settlement opportunity going forward, but it does not create a refund right for prior payments.

Step-by-Step Guide to Availing of the One-Time Abatement

Step 1: Confirm That You Are a Micro Taxpayer

The taxpayer must first determine whether gross sales for the year are less than ₱3,000,000.

For mixed income earners, exclude compensation income from employment. Only business income is considered for this purpose.

This step is important because the abatement under RR No. 4-2026 is limited to micro taxpayers.

Step 2: Check Your BIR Open Cases and Liabilities

Before applying, the taxpayer should identify all relevant BIR issues.

These may include delinquent accounts, assessments, pending protests, stop-filer cases, court cases, pending compromise settlement requests, pending abatement requests, or accounts payable to the BIR.

Taxpayers should check the taxable year, tax type, basic tax, penalties, interest, surcharge, and status of each case.

Step 3: Determine Whether the ₱80,000 Threshold Is Met

The taxpayer should compute the total basic tax liabilities and/or penalties for the covered taxable year.

If the total amount is not more than ₱80,000, the taxpayer may fall within the threshold provided by the regulation.

If the amount exceeds the threshold, the taxpayer should seek advice on other remedies or settlement options.

Step 4: Prepare the Application for Abatement

Micro taxpayers who wish to avail of the abatement must manually file an application on a per taxable year basis.

The application must use the BIR form attached to the regulation as Annex “A.”

The taxpayer must file the application with the Revenue District Office that has jurisdiction over the taxpayer.

Step 5: Specify the Tax Types and Basic Amount Due

The taxpayer must clearly specify the tax types and basic amount due, excluding interest, for each covered case.

This is a critical requirement.

Failure to specify the tax types and basic amount due in any covered case will result in denial of the application for abatement.

Taxpayers should avoid vague or incomplete applications. The application should be reviewed carefully before filing.

Step 6: Pay the ₱5,000 Abatement Fee

Once the application is accepted, the taxpayer must pay the ₱5,000 abatement fee using BIR Form No. 0605.

Payment may be made electronically or manually, in accordance with the applicable payment rules.

The payment must be made within five working days from the filing of the application.

Step 7: Submit Proof of Payment

After paying the ₱5,000 abatement fee, the taxpayer must submit proof of payment to the RDO within five working days from the date of payment.

This proof of payment is important because failure to submit it within the required period automatically voids the application.

However, the taxpayer may re-file within the availment period.

Step 8: Wait for the Certificate of Availment

The concerned RDO must issue a Certificate of Availment within five working days from receipt and verification of the proof of payment.

The Certificate of Availment serves as proof that the taxpayer availed of the abatement, complied with the requirements, and that the covered case is closed.

This certificate should be kept carefully for future BIR transactions, tax clearance, business closure, registration updates, and compliance records.

Step 9: Observe the Availment Deadline

Qualified taxpayers may avail of the benefits under RR No. 4-2026 until December 31, 2026, unless extended by the Secretary of Finance upon recommendation of the Commissioner of Internal Revenue.

Taxpayers should not wait until the last minute. Records may need to be reviewed, amounts verified, and documents prepared before filing.

What Happens if the Taxpayer Withdraws or Is Denied?

If the taxpayer withdraws the application or the application is denied, the ₱5,000 abatement fee will not be refunded.

Instead, it will be applied as partial payment to the taxes or penalties sought to be abated.

This is a key point taxpayers should understand before filing.

The abatement fee is not simply a refundable filing charge. It becomes part of the taxpayer’s payment if the application does not proceed successfully.

This makes it important to check qualification and documentation before filing.

What Happens if Proof of Payment Is Not Submitted on Time?

Failure to submit proof of payment within the required period automatically voids the application.

However, this is without prejudice to re-filing the same application within the availment period.

In practical terms, the taxpayer may still re-file if the program remains available, but the delay can create unnecessary inconvenience and risk.

Taxpayers should calendar the five-working-day payment and proof submission deadlines immediately.

Why This Is Important for Taxpayers Who Stopped Operating

Many micro taxpayers stop business operations without formally closing their BIR registration.

This can create continuing compliance problems. The taxpayer may continue to appear as registered and may accumulate open cases for non-filing of returns.

RR No. 4-2026 expressly includes covered cases of micro taxpayers who have ceased business operations.

This is significant because taxpayers who stopped operating may use the program to settle covered cases and move toward proper closure or cleanup of BIR records.

However, this regulation does not automatically cancel business registration. Taxpayers who ceased operations may still need to separately complete BIR closure procedures.

Common Mistakes to Avoid

One common mistake is assuming that the abatement is automatic. It is not. The taxpayer must apply, pay the fee, submit proof of payment, and obtain the Certificate of Availment.

Another mistake is failing to verify whether the taxpayer qualifies as a micro taxpayer. The gross sales threshold should be checked carefully.

Some taxpayers may also fail to include all covered cases for the taxable year or fail to specify the correct tax type and basic amount due. This can result in denial.

Others may miss the five-working-day deadline for paying the ₱5,000 fee or submitting proof of payment.

A final mistake is assuming that prior payments can be refunded. RR No. 4-2026 states that payments made before the effectivity of the regulations are not refundable.

Risks and Penalties

Taxpayers who ignore delinquent accounts, assessments, or stop-filer cases may face continuing penalties, collection action, difficulty securing tax clearance, complications in business closure, and problems with future BIR transactions.

For small businesses, these issues can be financially stressful. A relatively small unpaid liability can grow because of penalties and interest.

Open cases may also delay closure of business registration or renewal of compliance documents.

RR No. 4-2026 gives qualified micro taxpayers a chance to address covered cases, but failure to act within the availment period may mean losing the opportunity.

Practical Examples

Example 1: Small Online Seller With Stop-Filer Cases

An online seller registered with the BIR had gross sales below ₱3,000,000. The seller failed to file several returns in 2025 because the business had minimal activity.

The BIR records show open stop-filer cases and penalties within the ₱80,000 threshold.

The taxpayer may check whether the cases qualify under RR No. 4-2026, file the application with the RDO, pay the ₱5,000 abatement fee, and submit proof of payment on time.

Example 2: Micro Business With a Preliminary Assessment

A small retail business receives a Preliminary Assessment Notice issued before December 31, 2025. The assessed amount and penalties are within the threshold.

If the taxpayer qualifies as a micro taxpayer, the business may consider applying for abatement under RR No. 4-2026 instead of allowing the case to remain unresolved.

The taxpayer should still carefully review the assessment and confirm eligibility before filing.

Example 3: Taxpayer Who Stopped Operating

A freelancer registered as a business taxpayer stopped accepting clients but did not close BIR registration.

Because the taxpayer remained registered, open cases appeared for non-filing of required returns.

If qualified as a micro taxpayer and the open cases fall within the regulation’s coverage, the taxpayer may use the abatement program to settle covered liabilities. After that, the taxpayer may still need to complete proper business closure.

Example 4: Application Denied Due to Incomplete Details

A taxpayer files an application but fails to specify the tax type and basic amount due for one of the covered cases.

Under RR No. 4-2026, failure to specify these details results in denial of the application.

This shows why taxpayers should prepare the application carefully and verify the information before filing.

Best Practices for Micro Taxpayers

Micro taxpayers should first request or review their open cases with the BIR. They should identify the taxable year, tax type, amount, penalties, status, and whether the case existed as of December 31, 2025.

They should confirm whether gross sales are below ₱3,000,000 and whether the total liabilities and penalties are within the ₱80,000 threshold.

Before filing, taxpayers should prepare the application carefully and ensure all tax types and basic amounts are stated correctly.

After filing, taxpayers should immediately calendar the five-working-day deadline to pay the ₱5,000 abatement fee and the five-working-day deadline to submit proof of payment.

Once the Certificate of Availment is issued, the taxpayer should keep it permanently with tax records.

Call-to-Action

RR No. 4-2026 gives qualified micro taxpayers a valuable but time-limited opportunity to settle covered tax liabilities, penalties, and open cases.

For small business owners, freelancers, professionals, online sellers, and micro enterprises, this may be a chance to clean up BIR records, resolve old tax issues, and move forward with greater compliance confidence.

However, the process must be handled carefully. Eligibility, thresholds, tax types, basic amounts, filing deadlines, payment deadlines, and proof of payment requirements all matter.
