How Micro and Small Enterprises File Income Tax Returns on ITAS in Namibia

Learn how micro and small enterprises file income tax returns on ITAS in Namibia. Explore NamRA tax filing procedures, company schedules, provisional tax returns, financial statements and small business tax compliance.

Micro and small enterprises in Namibia must meet their income tax obligations regardless of their size, business structure or level of commercial activity. Whether you operate a Close Corporation (CC), a Private Limited Company (Pty Ltd) or a sole proprietorship, understanding how to file income tax returns correctly is essential for maintaining compliance with the Namibia Revenue Agency (NamRA).

NamRA provides the Integrated Tax Administration System (ITAS), an online platform that allows registered taxpayers to submit income tax returns, provisional tax returns, update taxpayer information and access tax account statements. Through the ITAS e-filing portal, business owners can manage many of their tax obligations without having to visit a NamRA office for every transaction.

However, filing business income tax returns involves more than simply logging into the portal and submitting figures. Businesses must identify the correct return, prepare accurate financial information, complete the applicable schedules, upload supporting documents and submit the required taxpayer declaration.

This guide explains how micro and small enterprises can file income tax returns on ITAS in Namibia, the information required, the filing process and important compliance considerations for business owners.

Understanding Income Tax Returns for Small Businesses in Namibia

Income tax is one of the key statutory obligations that businesses operating in Namibia must consider. Businesses earning taxable income may be required to submit annual income tax returns and provisional tax returns in accordance with the Income Tax Act, 1981 (Act No. 24 of 1981).

The Namibia Revenue Agency administers the country’s tax system and provides online filing services through ITAS.

Income tax returns Namibia requirements depend on the legal structure of the enterprise, its activities, accounting records and applicable tax obligations.

For micro and small enterprises, understanding these requirements is particularly important because many business owners manage their own administration and bookkeeping.

Which Businesses Must File Income Tax Returns?

Different business structures have different tax reporting obligations.

The following are common business structures operating in Namibia:

1. Close Corporations (CCs)

A Close Corporation is a separate legal entity registered with the Business and Intellectual Property Authority (BIPA). It must maintain appropriate accounting records and meet applicable corporate income tax filing obligations.

2. Private Limited Companies (Pty Ltd)

A private company is also a separate legal entity. It must register with NamRA, maintain financial records and submit the required company income tax returns. Entrepreneurs planning to establish this structure can review the forms and fees for registering a private company in Namibia.

3. Sole Proprietorships

A sole proprietorship is not a separate legal entity from its owner. Business income is generally reported as part of the individual’s taxable income, subject to the applicable tax rules and reporting requirements. For additional guidance, see how sole proprietors and partnerships submit individual income tax returns to NamRA.

4. Other Business Enterprises

Partnerships and other business arrangements may have different reporting obligations depending on their legal and tax status.

The legal structure of a business determines which taxpayer registration, return type and supporting documentation are relevant.

What Is ITAS and How Does It Help Small Businesses?

The Integrated Tax Administration System (ITAS) is NamRA’s electronic tax administration platform.

The ITAS e-filing portal enables registered taxpayers to access various tax services online. Instead of relying entirely on physical paperwork, businesses can use the platform to manage their tax accounts and submit relevant returns.

Services Available Through the ITAS Portal

Registered taxpayers can generally use ITAS to:

• Register for online tax services.
• Submit annual income tax returns.
• File provisional income tax returns.
• Submit applicable PAYE returns.
• Update contact and taxpayer information.
• View submitted tax returns.
• Obtain tax account statements.
• Access relevant tax information and services.
• Monitor certain outstanding tax obligations.

For small businesses, these services make tax administration more accessible and provide a central platform for managing tax compliance.

How to Access the NamRA ITAS Portal

Businesses can access the official ITAS portal through:

https://www.itas.namra.org.na

Existing users can log in using their registered credentials.

First-time users must complete the applicable ITAS registration process and link their taxpayer information to their online account.

It is important to use the official NamRA website when registering, accessing taxpayer information or submitting returns.

Requirements Before Filing Income Tax Returns on ITAS

Before starting the tax return filing process, business owners should prepare the necessary information and supporting documents.

Submitting incomplete or inaccurate information can result in processing delays, incorrect tax assessments or requests for additional documentation.

1. Taxpayer Identification Number (TIN)

A Taxpayer Identification Number is used to identify a taxpayer within NamRA’s tax administration system.

Businesses should ensure that their taxpayer registration details are correct and that the relevant tax types are activated where applicable.

For a newly registered company or Close Corporation, the taxpayer information should correspond with its BIPA registration details. Businesses that need assistance can consult this guide on obtaining a Tax Identification Number (TIN) certificate from NamRA in Namibia.

2. ITAS Registration and Login Details

The business or authorised representative must have access to the ITAS portal.

The registration process generally involves:

• Accessing the official ITAS website.
• Selecting the applicable registration or sign-up option.
• Providing the required taxpayer information.
• Completing the registration process.
• Activating the account through the verification process communicated by NamRA.
• Logging in using the registered credentials.

If the taxpayer already has an ITAS account, it is important to confirm that the correct taxpayer profile is accessible.

3. Financial Statements

Businesses should prepare financial statements covering the relevant accounting period.

Depending on the business structure and applicable requirements, these may include:

• Statement of comprehensive income.
• Statement of financial position.
• Cash flow information where applicable.
• Supporting accounting schedules.
• Notes explaining relevant financial transactions.

Financial statements help establish the business’s financial position and provide information needed to complete the income tax return.

Even micro enterprises with relatively few transactions should maintain proper financial records.

4. Income and Expenditure Records

Businesses should maintain detailed records of their income and expenses.

Relevant documents may include:

• Sales invoices.
• Receipts.
• Bank statements.
• Supplier invoices.
• Payroll records.
• Rental agreements.
• Business expense records.
• Asset purchase documents.
• Loan statements.

These records help ensure that income is reported accurately and that deductions are supported by appropriate evidence.

5. Employer Tax Identification Information

Businesses employing workers may have additional tax responsibilities.

For example, employers must consider their PAYE obligations and maintain appropriate employee tax records. Businesses that have not yet completed employer registration can review how to register as an employer for PAYE in Namibia.

The Employer’s Tax Identification Number and relevant employer information may be required when completing certain employee-related tax schedules.

The ITAS e-filing guidance also refers to the employer’s file identification number when entering employer details associated with PAYE documentation.

Businesses should ensure that employer and employee tax information is consistent with their NamRA records.

Step-by-Step Guide to Filing Company Income Tax Returns on ITAS

The following process explains how operational companies and Close Corporations can submit their income tax returns through ITAS.

The exact fields and schedules displayed may vary depending on the taxpayer’s registration, return type and assessment period.

Step 1: Log In to the ITAS Portal

Visit the official NamRA ITAS portal:

https://www.itas.namra.org.na

Enter your registered username and password.

If you have forgotten your login credentials, use the available account recovery options or contact NamRA for assistance.

Ensure that you are accessing the correct taxpayer profile before proceeding.

Step 2: Navigate to the Returns Section

After logging in:

1. Locate the Returns function on the portal.
2. Select My Returns.
3. Click Search Your Return.
4. Identify the relevant company income tax return.
5. Confirm that the assessment period corresponds to the financial year you intend to report.

This section allows taxpayers to locate the relevant returns associated with their registered tax accounts.

Step 3: Select the Company Income Tax Return

Locate the outstanding annual company income tax return.

Click the relevant File Your Return option to initiate the filing process.

Before proceeding, confirm that you have selected the correct return type and accounting period.

Submitting information against the wrong assessment period can create unnecessary complications when reconciling the taxpayer’s account.

Step 4: Complete the Mandatory Company Schedules

Company income tax returns on ITAS require taxpayers to complete applicable schedules containing information about their business activities and financial performance.

The NamRA guidance for operational companies identifies several schedules relevant to company and Close Corporation returns.

These include:

Schedule 28 and Schedule 29

These schedules contain compulsory corporate and Close Corporation information and questions relevant to the taxpayer’s business structure.

Taxpayers should provide accurate information about the enterprise and complete the applicable fields.

Schedule 14

This schedule captures trade income and expenditure incurred during the relevant assessment period.

Businesses should reconcile the information entered with their accounting records and financial statements.

Income and expenditure must be classified correctly, and expenses should be supported by appropriate documentation.

Schedule 16 and Schedule 17

These schedules relate to the summarised tax calculations, including applicable losses, taxable income and tax payable information.

Taxpayers should carefully review the figures to ensure that the information is consistent with the underlying financial records.

The availability and applicability of individual schedules should always be confirmed against the return displayed on ITAS and the relevant NamRA filing guidance.

Step 5: Enter Financial Information Accurately

When completing the return, ensure that all relevant financial information is entered correctly.

This may include:

• Total business income.
• Trading expenses.
• Operating expenses.
• Allowable deductions.
• Tax adjustments.
• Tax losses where applicable.
• Taxable income.
• Tax payable.

One common mistake among small business owners is treating all business expenses as automatically deductible.

Not every accounting expense qualifies for a tax deduction. Tax treatment must be determined according to the applicable provisions of the Income Tax Act. For additional information, read about how companies and Close Corporations calculate corporate income tax liability in Namibia.

Where an expense has both personal and business elements, the appropriate tax treatment should be established before including it as a deduction.

Step 6: Upload Supporting Financial Documents

After completing the required schedules, upload the supporting documents requested by the portal.

For operational companies, NamRA’s filing procedures refer to attaching the relevant financial statements for trading activities through the portal’s attachment facility.

Depending on the return and applicable requirements, supporting documents may include:

• Financial statements.
• Detailed income and expenditure schedules.
• Supporting tax computations.
• Other requested financial records.

Ensure that the uploaded documents are readable, complete and relevant to the assessment period.

It is advisable to keep copies of all submitted documents for future reference.

Step 7: Review the Taxpayer Declaration

Before submitting the return, carefully review the information entered.

Check that:

• The taxpayer’s details are correct.
• The accounting period is accurate.
• Income figures agree with the financial records.
• Expenditure has been classified correctly.
• Applicable schedules are complete.
• Supporting documents have been attached.
• Tax calculations are reasonable.

Once satisfied, proceed to the taxpayer declaration section.

Select the declaration checkbox to confirm the information provided.

Step 8: Complete Verification and Submit the Return

The ITAS filing procedure may require an additional verification step using a code communicated to the taxpayer’s registered contact details.

Enter the required verification code and click Submit.

Wait for the portal to process the submission.

After submission, check the relevant return status and retain any available confirmation or submission reference.

A return should not be assumed to have been successfully submitted simply because the taxpayer completed the online form. Always verify the submission status.

How to File Provisional Income Tax Returns on ITAS

Annual income tax returns are not the only tax obligations that operational businesses may have.

Businesses subject to provisional income tax requirements must also submit the applicable provisional returns during the relevant tax year.

Provisional tax allows taxpayers to make advance payments towards their estimated annual income tax liability.

This is particularly important for operational businesses that generate income throughout the year.

What Is Provisional Income Tax?

Provisional income tax is an advance payment of estimated income tax based on a taxpayer’s expected taxable income.

Instead of waiting until the end of the financial year to settle the entire tax liability, qualifying taxpayers make provisional payments according to the applicable requirements.

The calculation should be based on a reasonable estimate of taxable income rather than simply the amount of money deposited into the business bank account.

Steps for Filing Provisional Tax Returns

NamRA provides a separate filing procedure for operational companies submitting provisional income tax returns.

The general process is as follows:

1. Log in to the ITAS portal.
2. Navigate to the Returns section.
3. Select My Returns.
4. Click Search Your Return.
5. Locate the relevant provisional income tax return.
6. Open the return you intend to submit.
7. Complete the required provisional tax information.
8. Review the estimated taxable income and applicable tax calculations.
9. Complete the taxpayer declaration.
10. Submit the return and retain the confirmation.

Businesses should consult the relevant NamRA provisional income tax guidance to establish which provisional returns apply to them and when each must be submitted. Our guide to standard operating procedures for filing first and second provisional income tax returns in Namibia provides additional information.

Why Accurate Provisional Tax Estimates Matter

Small businesses sometimes underestimate their annual income when calculating provisional tax.

This can result in additional tax liabilities or penalties and interest where applicable.

For example, a company that expects to earn modest income at the beginning of the financial year may experience significant growth during the year.

Its provisional tax estimates should therefore be reviewed in accordance with the applicable rules and actual business performance.

Maintaining updated accounting records makes it easier to prepare reasonable estimates.

Income Tax Filing for Micro Enterprises and Small Businesses

Micro enterprises often operate with limited administrative resources. Some businesses do not employ dedicated accountants or bookkeepers, making tax compliance more challenging.

However, small business tax compliance does not become unnecessary simply because a business has limited turnover or few employees.

Business owners should understand their obligations and maintain sufficient records to support their tax returns.

Filing Returns for Businesses With Low or No Income

A business may have a financial year in which it generates little income or makes a loss.

This does not automatically mean that it has no tax filing obligations.

Where a company or Close Corporation remains registered and has outstanding returns, it should establish its filing requirements with NamRA.

A business that has stopped trading should not assume that it can simply stop submitting returns.

Its tax status and outstanding obligations should be addressed through the appropriate procedures.

Reporting Business Expenses

Micro enterprises should record their business expenses throughout the year instead of trying to reconstruct transactions when tax season arrives.

Examples of common business expenses include:

• Office rental.
• Internet and telephone services.
• Stationery.
• Business travel.
• Advertising and marketing.
• Professional fees.
• Employee salaries.
• Equipment and operational supplies.

Whether an expense qualifies for a tax deduction depends on its nature and the applicable tax rules.

Maintaining receipts, invoices and bank statements makes it easier to substantiate business expenditure.

Separating Personal and Business Transactions

One of the most important accounting practices for small businesses is separating personal and business transactions.

Mixing personal and business finances can make income tax filing more complicated.

Business owners should ideally maintain a dedicated business bank account and ensure that transactions are properly recorded.

Where owners withdraw money for personal use, those transactions should be recorded and classified appropriately.

This improves bookkeeping accuracy and makes the preparation of financial statements easier.

Income Tax Obligations for Active and Inactive Companies

Businesses must distinguish between being commercially inactive and having no outstanding tax obligations.

An operational company generates income or conducts business activities, while an inactive company may have temporarily stopped trading or may not have commenced operations.

However, inactivity does not necessarily remove statutory filing requirements.

Tax Returns for Active Companies

Active companies must maintain financial records reflecting their operations.

These records should capture income, expenses, assets, liabilities and other relevant transactions.

They should also monitor annual and provisional income tax obligations.

Tax Returns for Inactive Companies

An inactive company should establish its filing requirements based on its registration and tax status.

Even where no trading income was generated, the company may still need to submit outstanding returns or provide financial information requested by NamRA.

If a company is no longer intended to operate, its owners should investigate the appropriate deregistration or closure procedures rather than simply abandoning the entity. Businesses can learn more about compliance procedures for voluntary business tax deregistration and liquidation clearances in Namibia.

Common Mistakes Small Businesses Make When Filing Tax Returns on ITAS

Although the ITAS portal simplifies tax administration, taxpayers can still make mistakes when preparing and submitting their returns.

Understanding common filing problems can help businesses avoid unnecessary delays and compliance difficulties.

1. Filing the Wrong Tax Return

Businesses may select an incorrect return type or assessment period.

Before starting the filing process, confirm whether the outstanding obligation relates to an annual company return, provisional income tax return or another tax type.

2. Reporting Incorrect Business Income

Some business owners report only cash received without properly accounting for all relevant business income.

Income should be recorded and reported according to the applicable accounting and tax requirements.

3. Claiming Unsupported Expenses

Including personal expenses or unsupported deductions can result in incorrect tax calculations.

Businesses should maintain documentary evidence for expenses claimed in their tax returns.

4. Failing to Upload Financial Statements

Where supporting financial statements are required, failing to attach them can result in an incomplete submission or further requests from NamRA.

5. Ignoring Provisional Tax Obligations

Some enterprises focus entirely on annual returns and overlook provisional tax filing requirements.

Businesses should maintain a compliance calendar that includes all applicable filing periods.

6. Using Incorrect Taxpayer Information

Incorrect taxpayer details, outdated contact information or problems linking a taxpayer profile can interfere with online tax administration.

Business owners should periodically review their ITAS registration information.

7. Assuming That a New Business Has No Tax Obligations

Newly registered businesses should establish their tax obligations as soon as they commence registration and operational activities.

Waiting until the business becomes profitable can create unnecessary compliance problems.

How to Maintain Small Business Tax Compliance in Namibia

Good tax compliance begins with proper business administration.

Rather than preparing everything at the end of the financial year, micro and small enterprises should develop simple accounting and tax management procedures.

Maintain Monthly Accounting Records

Record all business transactions every month.

At a minimum, maintain:

• Sales and income records.
• Expense records.
• Bank reconciliations.
• Supplier invoices.
• Customer invoices.
• Payroll information where applicable.
• Asset and liability records.

Regular bookkeeping makes annual financial statement preparation significantly easier.

Monitor Tax Filing Deadlines

Businesses should identify all applicable annual and provisional filing deadlines.

The relevant deadlines may depend on the taxpayer’s classification, financial year and tax obligations.

Avoid relying on general deadlines without checking the specific requirements applicable to your business.

Review Your ITAS Tax Account Regularly

The ITAS portal provides access to taxpayer information and relevant tax account services.

Regularly reviewing your account can help identify:

• Outstanding tax returns.
• Unresolved tax obligations.
• Tax payments.
• Account balances.
• Relevant taxpayer information.

This supports better tax account management and reduces the likelihood of overlooking outstanding compliance matters.

Obtain Professional Accounting Assistance

Business owners who are unfamiliar with tax calculations, financial statements or ITAS schedules may benefit from professional accounting assistance.

A qualified accounting professional can help with bookkeeping, financial statement preparation, tax computations and reviewing the information before submission.

This is especially useful for enterprises with employees, multiple income sources, substantial transactions or complicated financial arrangements.

Businesses that need to establish their operations can also explore business registration services in Namibia, while entrepreneurs seeking to plan their operations and financial projections may benefit from professional business plan preparation services in Namibia.
