Rental income looks simple: tenants pay, you receive. But at the end of the year you must show how much came in, what it cost to earn it and whether the right tax was paid. Landlords who rely on memory spend days reconstructing the year; those who keep a simple routine finish in an hour. This guide gives you that routine.

Decide which tax route you are on

Before you can prepare anything, know which route you follow. Many residential landlords pay monthly rental income tax on gross rent, and do not deduct expenses. Others file an annual return and deduct allowable expenses. Which is better depends on how large your costs are, so compare them. MRI or annual rental tax explains both, and the rental income tax calculator shows the difference for your numbers. If you own several properties, read filing for several rental properties.

Record rent every time it arrives

Each month, record the rent received from each tenant: the date, the property, the amount and the method. Issue a receipt every time; the rent receipt book gives you numbered receipts. Keep a running balance for each tenant so arrears are visible straight away. The rental property and tenant register holds tenant details, rent due and payments in one place, and the monthly rental income tracker totals what you have received.

Record expenses as they happen

Every expense needs a date, the property, the type and the amount, with a receipt. The rental expense and deduction ledger marks what is allowable and keeps totals by type. The categories to expect are repairs and maintenance, agent fees, insurance, land rates, service charges and legal fees. Deductible expenses for landlords lists what counts, and repairs vs improvements separates a repair, which is deductible, from an improvement, which is not.

Handle withholding tax correctly

If a tenant is a company or an agent, it may deduct withholding tax from the rent and give you a certificate. Keep every certificate, since it is a credit against your tax. Check the rules in withholding tax on rent for tenants and agents and calculate the amounts with the withholding tax on rent calculator.

Reconcile every month

At the end of each month, compare the rent in your records with the money in your bank and M-Pesa statements. They should agree, with any differences explained by arrears or deposits. A monthly check takes minutes and prevents a nasty surprise at year end. Our guide to bank reconciliation, step by step shows the method.

Prepare the annual figures

At the year end, add up three totals for each property: the rent received, the allowable expenses and the withholding tax credits. If you file annually, the taxable income is rent less allowable expenses, and the tax is calculated on that. The rental income annual tax computation works through the steps. Check the deadline in the landlord's annual tax and compliance calendar, and file before it; late filing brings penalties, which you can estimate with the KRA penalty calculator.

Keep deposits separate

Tenant deposits are not income while you hold them for the tenant. Record them separately and do not spend them. When a deposit is kept for unpaid rent or damage, the retained amount is treated according to what it covers. Mixing deposits with rent is one of the easiest ways to confuse your accounts.

Store your records

Keep rent records, receipts, expense documents, agreements and tax filings for at least five years. Organise them by property and by year, in paper or digital folders. Records every landlord should keep provides the full list, and how to organise your tax documents through the year suggests a folder structure.

A year-end checklist

  1. Confirm all rent received is recorded and reconciled.
  2. Total the expenses and check each has a receipt.
  3. Gather withholding tax certificates.
  4. Choose the tax route and compute the tax.
  5. File the return and pay any tax due.
  6. Back up the files and note next year's deadlines.

Following the same routine every year turns a stressful task into a quiet one, and gives you the figures you need to decide whether a property is really earning its keep.

What good records give you

Beyond tax, tidy rental accounts tell you which property earns the most, which tenants cost you time and when a repair bill is out of line. Review the totals each quarter, compare them with the same period last year and adjust rents, agents or maintenance plans accordingly. The accounts then become a management tool, not just a tax chore.
