How to File ZRA Nil Returns in Zambia 2026, Step‑by‑step (TPIN, Taxonapp, Deadline)

Every taxpayer registered with the Zambia Revenue Authority (ZRA) must file returns for each tax period, even when there is absolutely nothing to report. Understanding how to file ZRA nil returns correctly is one of the most common compliance questions during filing season, and getting it wrong (or ignoring it entirely) triggers penalties that accumulate quickly. This guide walks individual taxpayers, small‑business owners and accountants through every click on both the ZRA web portal and the TaxOnApp mobile application, covers the key 2026 deadlines published by ZRA, and explains how to fix the errors that stall most first‑time filers.

Whether you are filing a nil income‑tax return or a monthly nil VAT return, the step‑by‑step instructions below will keep you compliant.

Quick Checklist, What You Need Before You Start

Before you log in to the ZRA portal or open TaxOnApp, confirm you have every item on this checklist. Missing even one credential will stop the process mid‑flow.

• Taxpayer Identification Number (TPIN). Your ten‑digit TPIN is the primary login credential for all ZRA e‑services. If you have not yet registered, visit the ZRA Tax Information page for registration guidance.
• ZRA portal account credentials. You need the username (usually your TPIN) and password you created when you first registered on portal.zra.org.zm.
• TaxOnApp installed (mobile filers). Download the latest version from the Google Play Store or Apple App Store. The app is free and published by the Zambia Revenue Authority.
• Valid email address and phone number. ZRA sends acknowledgements and one‑time passwords (OTPs) to the contact details on your profile.
• Tax obligation details. Know exactly which tax head you are filing under, Income Tax (Resident Individual or Company), VAT, or another obligation registered against your TPIN.
• Return period. Identify the exact period, for example, the charge year for annual income tax or the specific month for VAT.
• Stable internet connection. Session timeouts are the single most common complaint; a reliable connection prevents lost work.

Can you file your income tax return yourself online? Yes, any individual taxpayer or authorised representative with valid TPIN credentials can complete the entire process on the ZRA portal or TaxOnApp without visiting a ZRA office.

What Is a ZRA Nil Return?

A ZRA nil return is a tax return submitted to the Zambia Revenue Authority declaring that no taxable income was earned, no taxable supplies were made, or no tax liability arose during the relevant return period. It is not an exemption from filing, it is the act of filing itself, with all reportable figures entered as zero. The ZRA Post‑Registration Requirements guide makes clear that registered taxpayers must continue submitting returns on time regardless of whether any business activity occurred during the period.

Nil returns apply across multiple tax heads. An individual with no employment or business income for the charge year submits a nil income‑tax return. A VAT‑registered trader who made no taxable supplies during a given month submits a nil VAT return. In each case, the obligation to file exists because the taxpayer holds an active registration with ZRA, not because a liability has actually accrued.

Do You Need to File? Who Must Submit a ZRA Nil Return

Not every Zambian resident needs to file a nil return, only those who hold an active tax registration with ZRA. The table below summarises the most common scenarios.

If you are unsure whether your TPIN is still active, log in to the ZRA portal and check your registered obligations. An active obligation that goes unfiled will generate an automatic penalty, even if you believed the registration had lapsed. Industry observers note that many small businesses accumulate years of penalty debt simply because they assumed dormancy equalled deregistration.

Deadlines and Penalties for ZRA Nil Returns (2026)

Missing the income tax return due date in Zambia is expensive. The ZRA penalties framework imposes both fixed penalty charges and daily interest on outstanding amounts, and these apply to nil returns just as they do to returns with a positive tax liability. Filing on time, even when the return is nil, is therefore not optional.

Key 2026 Filing Deadlines

• Provisional income tax (individuals and companies). Quarterly instalments are due on 31 March, 30 June, 30 September and 31 December of the charge year. Nil provisional returns should still be submitted by each date if no estimated liability exists.
• Annual income‑tax return (self‑assessment). Due by 21 June of the year following the end of the charge year. For the charge year ending 31 December 2025, the return is due 21 June 2026. Taxpayers should confirm this date against the latest ZRA official notice, as ZRA occasionally extends deadlines via gazette.
• Monthly VAT return. Due by the 18th day of the month following the VAT period. A nil VAT return for May 2026, for example, must be filed by 18 June 2026.

Penalty Exposure

The ZRA penalties page outlines the consequences of late filing. Penalties are charged as a fixed amount per return period, and interest accrues on any assessed tax from the due date until payment. Even where the underlying tax is zero, the late‑filing penalty itself becomes a debt owed to ZRA. Taxpayers who accumulate multiple unfiled periods face compounding penalty charges that can reach substantial sums. If you have already missed a deadline, the recommended course of action is to file immediately, the penalty clock stops on the date the return is received, and then seek professional advice on whether grounds exist to apply for penalty relief.

Late filing penalties, appeals and how to request relief from ZRA is a topic that warrants its own detailed treatment.

Step‑by‑Step: How to File ZRA Nil Returns on the Web Portal

The ZRA Tax Online portal is the primary channel for submitting ZRA nil returns from a desktop or laptop. The procedure below follows the flow described in ZRA’s official “How to file a nil return” guide.

Accessing the ZRA Portal

1. Open a modern web browser (Chrome, Edge or Firefox recommended) and navigate to portal.zra.org.zm.
2. On the landing page, locate the Login section.

Logging In with Your TPIN

3. Enter your TPIN in the username field.
4. Enter your password. If you have forgotten your password, use the “Forgot Password” link, ZRA will send a reset link to the email address associated with your TPIN profile.
5. Complete any CAPTCHA or OTP verification prompted by the system.
6. Click Login. You will be directed to your taxpayer dashboard.

Creating a New Return

7. From the dashboard, navigate to the Returns menu (sometimes labelled “e‑Returns” or “Tax Returns” depending on the portal version).
8. Select File Return or New Return.
9. The system will display the tax obligations registered against your TPIN.

Choosing Your Tax Obligation

10. Select the appropriate tax head, for example, Income Tax, Resident Individual, Income Tax, Company, or Value Added Tax.
11. Choose the return period (charge year for income tax, or specific month for VAT).
12. Click Next or Proceed to open the return form.

Entering Nil Figures

13. The return form will display fields for income, deductions, tax payable and related figures. Enter zero (0) in every applicable monetary field.
14. Some return forms include a dedicated “Nil Return” checkbox or toggle, if present, select it. This auto‑populates all fields with zero and locks the form against accidental entries.
15. Review every section of the form. Ensure no pre‑populated amounts remain from a previous period.

Submitting and Viewing the Acknowledgement

16. Click Validate (if available) to let the system check for errors before final submission.
17. If validation passes, click Submit.
18. The portal will generate an acknowledgement receipt, a confirmation page displaying the return reference number, submission date, tax period and taxpayer TPIN.

Downloading the Acknowledgement

19. Click Download or Print to save the acknowledgement as a PDF.
20. Store this PDF securely, it is your proof of timely filing and may be required during audits or when applying for tax‑clearance certificates.

This completes the web‑portal process for how to file ZRA nil returns. The entire procedure typically takes fewer than ten minutes once you are logged in.

Step‑by‑Step: How to File ZRA Nil Returns on TaxOnApp (Mobile)

TaxOnApp is ZRA’s official mobile application and is the fastest way to submit nil returns on the go. The steps below mirror the flow shown in ZRA’s official video tutorials.

1. Install or update TaxOnApp. Search “TaxOnApp” on the Google Play Store or Apple App Store. Ensure you have the latest version to avoid compatibility errors.
2. Open the app and log in. Enter your TPIN and password. If prompted, complete OTP verification sent to your registered mobile number.

4. Select tax obligation. The app lists all active obligations linked to your TPIN. Tap the relevant one (e.g., Income Tax, VAT).
5. Choose the return period. Select the charge year or month you are filing for.
6. Mark the return as nil. If a nil‑return toggle is available, enable it. Otherwise, enter zero in every monetary field.
7. Review and submit. Scroll through the summary screen to confirm all values are zero, then tap Submit.
8. Save acknowledgement. The app will display a confirmation with a reference number. Take a screenshot or use the in‑app download option to save the receipt.

TaxOnApp Troubleshooting Tips

• App crashes on login. Clear the app cache (Settings → Apps → TaxOnApp → Clear Cache) and retry. If the problem persists, reinstall.
• OTP not received. Ensure the mobile number on your ZRA profile is current. Contact ZRA on the toll‑free line 4111 if the number needs updating.
• Return period not visible. This usually means the period has not yet opened or a return has already been filed. Check your filing history in the app.
• “Session expired” mid‑submission. Log in again promptly, the app times out after a period of inactivity. Work on a stable data or Wi‑Fi connection.

TPIN: Registration, Reset and Common Issues

Your TPIN is the gateway to every ZRA e‑service. Without it, you cannot file any return, nil or otherwise. Here is a concise overview of the most common TPIN issues and how to resolve them.

• New TPIN registration. Apply through the ZRA portal or visit any ZRA office with your National Registration Card (NRC) or passport. ZRA’s Tax Information page provides the full list of required documents. How to register for a TPIN and ZRA portal access is covered in greater detail in a separate guide.
• Forgotten password. Use the “Forgot Password” function on the portal login page. A reset link is sent to your registered email. If you no longer have access to that email, contact ZRA directly.
• Blocked or locked TPIN. Multiple failed login attempts can lock your account. Call ZRA’s toll‑free line (4111 within Zambia) or visit your nearest ZRA office with identification to have the account unlocked.
• Updating contact details. Changes to your email, phone number or physical address must be submitted through the portal’s profile section or in person at a ZRA office. Keeping these details current prevents missed OTPs and correspondence.

Common Errors, Troubleshooting and Screenshots to Capture

Even experienced filers encounter portal glitches. The list below covers the errors reported most frequently by taxpayers learning how to file ZRA nil returns, along with recommended fixes.

• “Invalid TPIN or Password.” Double‑check that you are entering the ten‑digit TPIN (not your NRC number). Reset your password if uncertain.
• “Session Timeout, Please Login Again.” This occurs after prolonged inactivity. Log in again, and complete the return in a single sitting to avoid data loss.
• “Return Already Filed for This Period.” The system does not allow duplicate returns. If you need to amend a previously submitted nil return, look for the Amend Return option in your filing history.
• “Invalid Return Period.” Ensure you have selected a period that has closed and that matches your registered obligation. You cannot file a return for a future period.
• “Validation Error, Required Fields Missing.” Even on a nil return, certain fields (taxpayer details, period, declaration checkbox) must be completed. Scroll through every tab of the form before submitting.
• Portal loading slowly or displaying a blank page. Try a different browser, clear your cache, or attempt filing during off‑peak hours (early morning or late evening).
• “Payment Reference Number (PRN) Required.” A nil return with zero liability should not require a PRN. If the system prompts for one, confirm that all monetary fields are truly zero and that no outstanding assessment exists for the period.

Screenshots to capture during filing: Take a screenshot of (1) the completed return form showing zero entries, (2) the submission confirmation screen, and (3) the acknowledgement receipt with reference number. These serve as evidence of timely compliance.

After Submission, Record Keeping, Payment and Appeals

Once your nil return is submitted, the hard work is done, but a few follow‑up steps protect you going forward.

• Store the acknowledgement receipt. Keep the PDF or screenshot for a minimum of six years, consistent with ZRA’s record‑retention expectations. This document proves you filed on time if a dispute arises.
• Check your filing history. Log back in to the portal periodically to confirm the return appears as “Filed” or “Submitted” for the correct period.
• No payment required. A genuine nil return carries zero tax liability, so no payment or PRN is needed. If the portal shows an outstanding balance against the period, investigate, it may indicate a previously raised assessment or a penalty from an earlier late filing.
• Appealing penalties. If penalties were charged for a period you believed was covered, you may apply to ZRA for remission or lodge a formal objection. The process involves writing to the Commissioner‑General within the statutory timeframe. Professional legal advice is strongly recommended for penalty appeals.

Conclusion

Filing ZRA nil returns is a straightforward compliance task that protects you from unnecessary penalties and keeps your tax record clean. Whether you use the web portal at portal.zra.org.zm or file on the go via TaxOnApp, the process takes minutes once your TPIN credentials are in order. The critical takeaway for 2026 is to file before the deadline, 21 June for annual income‑tax returns, the 18th of each following month for VAT, because penalties accrue regardless of whether any tax is actually owed. If you have accumulated unfiled periods, face penalty assessments, or need help navigating the objection and appeal process, connecting with an experienced Zambia‑based tax lawyer can make a significant difference in the outcome.
