eRITS: How Nairobi Landlords Register on KRA's New Rental Income System

If you collect rent from a unit anywhere in Nairobi, eRITS is now part of your year. The Kenya Revenue Authority's electronic Rental Income Tax System changes how residential rent is reported, who sees what, and how quickly mismatches turn into queries on your iTax account. For eRITS Kenya landlords, the shift is less about paying more tax and more about being visible. This guide walks you through what eRITS actually is, who must register, the documents to gather, the on-screen steps, and the everyday mistakes that pull landlords into avoidable correspondence with KRA.

What eRITS Is and Why KRA Rolled It Out

eRITS is a module within iTax that captures rental information at the unit level. Instead of declaring a single annual rent figure, landlords now list each property, link individual units to identified tenants, and record monthly rent receipts. KRA's intent is straightforward: close the visibility gap between what landlords report and what tenants actually pay.

The system has been built to cross-reference landlord declarations with tenant PINs, mobile money paybills, and bank deposit patterns. That pairing of data sources is what makes eRITS different from the older rental income return. Where a paper-thin declaration once passed unchallenged, the new module flags inconsistencies in near real time.

For honest landlords, eRITS is mainly an administrative shift. For landlords who have under-declared, it removes the room to manoeuvre. Either way, the practical reality is the same: every Nairobi landlord with a residential unit in active letting needs a clean eRITS profile.

Who Must Register

The default position is broad. If you earn residential rental income in Kenya, you fall within the eRITS perimeter. That includes:

• Single-unit landlords: the owner of one let bedsitter in Kileleshwa is in scope, just as the owner of a thirty-unit Westlands block is.
• Joint owners: spouses or family co-owners must agree who declares, or split declarations by ownership share.
• Diaspora landlords: being abroad does not exempt you. Rental income sourced from a Kenyan property remains taxable in Kenya.
• Trustees and executors: rent collected under estate administration is reportable through the estate's PIN.
• Agents collecting on behalf: letting agents and managers can be registered as third-party filers, but the income still belongs to the owner for tax purposes.

Commercial premises follow a different regime, which is covered separately under the standard income tax rules. Mixed-use buildings need careful treatment so that the residential portion is reported through eRITS while commercial floors run through the regular return.

Documents You Need Before You Start

Most failed registrations come down to one missing field. Before you log in, gather:

• Your KRA PIN and iTax password.
• Title deed reference, sectional title number, or registered lease for each property.
• Physical address with the LR number, plot number, or sectional unit reference.
• Tenant details: full name, KRA PIN, contact number, tenancy start date, and monthly rent agreed.
• Bank account details and any M-Pesa paybill or till number used for rent collection.
• For diaspora landlords, a working mobile number that can receive iTax verification messages.

If you let through a managing agent, decide upfront whether the agent will file or whether you will. Both routes are valid; mixing them mid-year is what creates the trouble.

Step-by-Step Registration on iTax and the eRITS Module

The flow is sequential. Skipping a step rarely works, even if a later one feels obvious.

Logging In and Updating Your Profile

Sign in at the iTax portal using your PIN and password. Before you touch eRITS, refresh your taxpayer profile: contact details, registered address, and the obligations attached to your PIN. If "Monthly Rental Income" is not listed as an active obligation, add it through the obligation update page first. eRITS will not accept a property declaration if the obligation is not switched on.

Declaring Your Properties</h3

Inside the eRITS module, open the property register and add each building or stand-alone unit. You will be asked for the title or sectional reference, the LR or plot number, and a count of lettable units. Be precise: if a block has eighteen units but two are owner-occupied, declare eighteen total and mark the two as non-let. Misstating the unit count is one of the most common reasons KRA opens a follow-up.

Linking Units to Tenants

For every let unit, attach a tenant. The system requires the tenant's name and KRA PIN. Where a tenant cannot supply a PIN, there is a flag for that, but expect the unit to be tagged for follow-up if the gap continues for more than a couple of months. The tenancy start date and monthly rent must match the lease document you would produce in an audit.

Confirming Submission

Once units and tenants are mapped, submit the registration. The portal issues a confirmation acknowledgement. Save the PDF. From the following month, your filing obligation runs automatically through the same module: you log monthly receipts, generate a payment reference, and settle through any approved bank or mobile channel.

Common Errors That Trigger KRA Queries

Three patterns account for most of the queries we see on landlord accounts in Nairobi.

• Mismatched tenant PINs: the tenant gives you a PIN that belongs to a relative, or an old PIN from a closed business. eRITS reconciles tenant rent claims against the PIN you supply, and the mismatch flags both parties.
• Undeclared units: a quietly let outbuilding, a converted servants' quarter, a granny flat used as an Airbnb. If money flowed through your paybill or bank, KRA can see it. Declare it in the property register, even if it is on a short let.
• Late filing: the monthly return falls due regardless of whether the unit was occupied. A nil return is still a return.
• Mixing residential and commercial: ground-floor shops in a residential block need to come out of the eRITS computation. Putting them in inflates your rental base and complicates the year-end reconciliation.
• Stale tenant records: when a tenant moves out, update the unit status. Continuing to declare a vacated unit as occupied is just as flag-worthy as under-declaring it.

None of these are difficult to avoid once you know to look for them. Most start as small administrative oversights that compound into larger queries because the eRITS audit trail keeps a complete history.

Across our portfolio, the landlords who let us run eRITS file on time, every month, with no surprises.

Practical Habits That Keep Your eRITS Profile Clean

Once registered, a small amount of monthly discipline keeps you out of trouble:

1. Reconcile your bank or paybill statement against your eRITS submission within seven days of month-end.
2. Capture every new tenant in the system on the day they sign, not when the first rent comes in.
3. Update vacated units immediately. Nil months are simpler to file when the unit status is correct.
4. Keep digital copies of leases, deposit receipts, and any rent variation letters in a single folder per property.
5. If KRA sends a clarification request through iTax, respond within the window stated. Silence escalates faster than a wrong answer that you correct.

Frequently Asked Questions

Is eRITS optional for landlords in Kenya?

No. If you earn residential rental income in Kenya, eRITS registration is the default obligation, not a choice. Whether you own one bedsitter or a multi-unit block in Nairobi, your rental obligation must be active on iTax and your properties declared in the eRITS module. Diaspora landlords are equally in scope. Choosing not to register simply moves you into KRA's enforcement queue.

What if my tenant has no KRA PIN?

Capture the unit in eRITS and use the no-PIN flag in the tenant record. Then ask the tenant to apply for a PIN through iTax, which is free and quick for resident individuals. Continuing without a PIN beyond a couple of months tends to attract follow-up correspondence. For diaspora or transient tenants, your letting agent can document the position so KRA understands the context.

How does eRITS treat agents collecting rent on my behalf?

Agents can be set up as third-party filers on your iTax profile, which lets them submit the monthly eRITS return for you. The income still belongs to the owner for tax purposes, and the obligation stays attached to the owner's PIN. The agent's role is operational. REAL Management Services routinely files eRITS for landlords under this arrangement, with reconciled rent records each month.

What are the penalties for not registering on eRITS?

Non-registration and late filing both attract statutory penalties under the Tax Procedures Act, and interest accrues on unpaid rental tax until settled. Beyond the cash cost, an undeclared portfolio that surfaces through tenant PIN cross-checks tends to draw a wider audit covering several previous years. The cleaner approach is to register, file from this month, and use a voluntary disclosure path for any historic gaps.

How often do I file once registered on eRITS?

Filing is monthly. The return for a given month falls due by the statutory deadline of the following month, irrespective of whether your units were occupied. If a unit was vacant, you file a nil entry for that unit. Skipping a month, even when there is no rent to declare, counts as late filing. Setting a recurring calendar reminder, or letting a manager run the filing, keeps the cycle clean.
