How to File Your KRA Tax Returns Online in Kenya: Complete iTax Guide for 2026

Filing tax returns with the Kenya Revenue Authority (KRA) is an annual obligation for every person and entity holding a KRA PIN. The iTax platform has simplified the process, allowing taxpayers to file returns online from anywhere in the world. However, many Kenyans — especially those in the diaspora — find the process confusing or overlook important deductions and reliefs that could save them significant money. Understanding how to properly file your tax returns, declare all income sources, and claim available reliefs is essential for maintaining tax compliance and minimizing your tax burden. This comprehensive guide walks you through the complete iTax filing process for 2026.

Who Must File Tax Returns in Kenya?

Every individual and entity with a KRA PIN in Kenya is required to file annual income tax returns, regardless of whether they earned any income during the tax year. This includes employed persons, self-employed individuals, business owners, landlords, and even students or unemployed persons who have registered for a KRA PIN. The filing deadline is June 30th of each year for the tax period January 1st to December 31st of the preceding year.

Failure to file your tax returns on time attracts automatic penalties from the Kenya Revenue Authority. For individuals, the late filing penalty is KES 2,000 per month or 5% of the tax due (whichever is higher), up to a maximum of KES 48,000. For companies, the penalty is KES 20,000 per month. These penalties accumulate even for nil returns (where no tax is due), making timely filing essential.

Diaspora Kenyans with KRA PINs must also file returns, even if all their income is earned abroad. Non-residents are generally only taxed on Kenya-sourced income, but the obligation to file a return remains. Filing nil returns maintains your tax compliance status and avoids unnecessary penalties that can become significant over time.

Types of Income to Declare

Kenya taxes various categories of income differently. Employment income (PAYE) is the most common — if you are employed, your employer deducts Pay As You Earn tax monthly and remits it to KRA. At year-end, your employer provides a P9 form summarizing your annual earnings and taxes paid, which you use to file your return.

Rental income from property in Kenya is taxed at graduated rates or under the simplified rental income tax regime (for residential properties with annual rent not exceeding KES 15 million). Business income from sole proprietorships and partnerships is subject to individual income tax rates. Investment income — including dividends from shares, interest from bonds and bank deposits, and capital gains from property sales — is also declarable.

Other taxable income includes pension income, income from digital content creation, income from the gig economy, and any other economic benefit received in Kenya. Tax-exempt income (such as infrastructure bond interest) should still be declared in the appropriate section of the return for completeness, even though no tax is due on it.

Step-by-Step iTax Filing Process

Step 1: Log into the KRA iTax portal at itax.kra.go.ke using your KRA PIN and password. If you have forgotten your password, use the 'Forgot Password' option to reset it via your registered email or phone number. Navigate to the 'Returns' menu and select 'File Returns.'

Step 2: Select the appropriate return type. For most individuals, this is the 'Income Tax - Resident Individual' return (IT1 form). If you are a non-resident, select the 'Non-Resident Individual' return. The system will present the return form with pre-populated data where available (such as PAYE from employer submissions).

Step 3: Fill in all applicable sections of the return — employment income (using your P9 form), business income (from your financial records), rental income, other income, deductions, and reliefs. Allowable deductions include pension contributions (up to KES 240,000), mortgage interest (up to KES 300,000), insurance premiums, and charitable donations. After completing all sections, the system calculates your tax liability. Review the summary, acknowledge the declaration, and submit your return.

Tax Reliefs and Deductions Available

Kenya's tax system provides several reliefs and deductions that can reduce your tax liability. Personal relief of KES 28,800 per year is automatically applied to all resident individual taxpayers. Insurance relief of up to KES 60,000 per year is available for premiums paid on life insurance, education policies, and health insurance (including NHIF/SHA contributions).

Mortgage interest relief allows homeowners to deduct up to KES 300,000 in annual mortgage interest payments on their owner-occupied residential property. Pension contribution relief covers contributions to registered pension schemes up to KES 240,000 per year. Disability exemption provides complete tax exemption for persons with severe disabilities whose total income does not exceed KES 150,000 per month.

Home ownership savings plans (HOSP) registered with the Commissioner of Domestic Taxes allow tax-free savings of up to KES 96,000 per year towards the purchase of a first home. Additionally, contributions to the Affordable Housing Levy (1.5% of gross salary) are tax-deductible. Understanding and claiming all available reliefs can significantly reduce your tax burden.

Common Filing Mistakes and How to Avoid Them

The most common mistake is failing to file altogether, resulting in accumulating penalties. Even if you have no income to report, you must file a nil return. Another common error is using the wrong return type — ensure you select the correct form based on your residency status and income sources.

Incorrect or incomplete P9 information is another frequent issue. Always verify the figures on your P9 form with your actual payslips before entering them on iTax. If there are discrepancies, contact your employer's HR department for a corrected P9. Failing to declare all income sources (especially rental income and investment income) is a compliance risk, as KRA increasingly uses data from third parties (banks, rental platforms, CDSC) to verify taxpayer declarations.

If you discover an error after filing, you can submit an amended return through iTax within 12 months of the filing deadline. However, if the amendment results in additional tax due, interest and penalties may apply. It is better to file accurately the first time by gathering all your income documents, consulting with a tax advisor if needed, and carefully reviewing the return before submission.
