Rental Property Accounting Basics for Small Landlords

Ask a typical small landlord in Bangladesh how much their building actually earned last year, and the answer is often a rough guess. Rent comes in cash, by bKash and by bank transfer; repairs are paid from a personal wallet; the guard's salary, the lift servicing and the holding tax are scattered across notebooks and memory. Rental property accounting sounds like something for large companies, but a few simple habits can tell you exactly what you earn, who owes you money, where costs are rising, and what to show when filing your income tax return.

This guide covers the basics for owners of a few flats, a house with several units, or a small group of shops: what to record, how to organise income and expense categories, how to track dues and deposits, how to calculate net income, and how to prepare for tax time. No accounting degree required.

Why Small Landlords Need Basic Accounting

• Know your real profit: gross rent is not income. After maintenance, staff, utilities, taxes and vacancies, the real return can be much lower.
• Track dues accurately: without records, it is easy to forget a partial payment or argue with a tenant about what was paid.
• Handle advances and deposits correctly: these belong partly to the tenant and must be tracked separately.
• File taxes with confidence: rental income is taxable under the Income Tax Act 2023, and good records make the return easier and reduce the risk of mistakes.
• Make better decisions: whether to raise rent, renovate, change the service charge or sell depends on numbers you can trust.
• Family transparency: in family-owned buildings, clear accounts prevent disputes between siblings and heirs.

Keep Rental Money Separate from Personal Money

The single most helpful habit is to use a separate bank account (and, if possible, a separate mobile financial service account) for your rental business. All rent goes in; all property expenses go out. Personal spending comes from a transfer to your personal account, not directly from rental cash.

This one change makes your bank statement a rough record of the rental business on its own. If you collect cash rent, deposit it into this account regularly instead of spending it directly.

The Four Records Every Landlord Should Keep

1. Rent roll (tenant and unit list)

A list of every unit with the tenant's name, rent, service charge, due date, agreement start and end dates, advance and security deposit amounts. This is your master reference.

2. Rent ledger (income record)

For each tenant, a month-by-month record of what was due (rent, service charge, electricity from sub-meter, other charges), what was paid, the date, the method and the balance. This shows at a glance who is up to date and who owes money. Our article on the benefits of a digital rent ledger explains why many landlords move this record from paper to software.

3. Expense record

Every cost of running the property with date, amount, category, payee and a receipt or photo of the bill.

4. Deposits and advances register

For each tenant, how much advance and security deposit was received, how much has been adjusted against rent or deductions, and the balance still held.

Setting Up Income and Expense Categories

Consistent categories let you compare months and years. Keep the list short and practical.

Repairs vs improvements

Fixing a leaking pipe is a repair, a normal running cost. Replacing all bathrooms or adding a lift is an improvement, a capital expense that adds long-term value. Keep them apart. Mixing a one-off Tk 800,000 renovation with regular monthly costs makes a single year look like a disaster and hides the real running costs. How improvements are treated for tax may also differ; ask your tax adviser.

Advances and Security Deposits Are Not Income (Yet)

This is the most common accounting mistake among Bangladeshi landlords. When a tenant pays Tk 60,000 as a security deposit, that money is not your earnings; you owe it back at the end of the tenancy, less any lawful deductions. Record it as a liability (money held on behalf of the tenant), not as rent.

Advance rent is similar: it becomes rent income only as each month it covers passes. If a tenant pays Tk 60,000 advance for a flat at Tk 20,000 per month, to be adjusted over the last three months of the tenancy, it is income in those three months, not on the day it was received.

For example (illustrative): In January, a new tenant of a Tk 20,000 flat pays: January rent Tk 20,000, security deposit Tk 40,000 and advance Tk 40,000, to be adjusted at Tk 5,000 per month for 8 months from February. Total received: 20,000 + 40,000 + 40,000 = Tk 100,000. Only Tk 20,000 of that is January's rent income.

The rule is simple: rent income each month equals that month's rent, whether it was paid in cash or covered by the advance. The advance balance falls by the adjusted amount (8 x 5,000 = 40,000 by the end of September); the security deposit stays at Tk 40,000 until move-out.

Tip: Every time you issue a receipt, note how much came as cash or transfer and how much was adjusted from the advance. Many end-of-tenancy disputes are really about the advance balance.

The Premises Rent Control Act 1991 contains provisions on advances and receipts. Our guide to advance rent and security deposits in Bangladesh covers the practical and legal points.

A Simple Monthly Accounting Routine

1. Day 1 to 2: generate each tenant's monthly bill (rent, service charge, sub-meter electricity, other charges).
2. As payments arrive: record each payment in the rent ledger and issue a receipt.
3. Weekly: enter expenses with receipts; photograph paper bills.
4. Around day 10: review the due list and send polite reminders.
5. Month end: reconcile: compare the ledger with the bank and mobile banking statements and the cash in hand. Every Taka should match.
6. Month end: produce a one-page summary: total billed, total collected, total dues, total expenses, net cash.

If the building has several owners

Many buildings in Bangladesh are owned jointly by siblings or family members, or have floors belonging to different heirs. In that case, agree in writing whose units are whose, how common costs such as the guard, lift and holding tax are shared, and who keeps the accounts. A monthly one-page statement shared with every co-owner, showing each owner's rent collected, share of common expenses and net amount due, prevents most family disagreements before they start.

A simple year-end review

Once a year, compare the twelve monthly summaries side by side. Look for expense categories that grew sharply, units with repeated late payments, months with vacancy, and the total advance and security deposit balances you hold. Check every tenant's agreement end date for the coming year. This one-hour review often reveals more useful decisions, such as a service charge that no longer covers costs or a unit that needs repair before it can be re-let at a better rent, than a whole year of day-to-day bookkeeping.

Calculating Net Rental Income: A Worked Example

For example (illustrative): A small building in Dhaka has 6 flats at Tk 18,000 each and 2 ground-floor shops at Tk 25,000 each. In one year, one flat was vacant for 2 months.

Income

• Flats potential rent: 6 x 18,000 x 12 = Tk 1,296,000
• Less vacancy: 1 flat x 2 months x 18,000 = Tk 36,000
• Flats actual rent: 1,296,000 minus 36,000 = Tk 1,260,000
• Shops: 2 x 25,000 x 12 = Tk 600,000
• Total rent income: 1,260,000 + 600,000 = Tk 1,860,000

Operating expenses

• Guard and caretaker salaries: Tk 216,000
• Common electricity and water pump: Tk 48,000
• Repairs and maintenance: Tk 95,000
• Holding tax and municipal charges: Tk 30,000
• Cleaning and waste: Tk 24,000
• Total operating expenses: 216,000 + 48,000 + 95,000 + 30,000 + 24,000 = Tk 413,000

Result

• Net operating income: 1,860,000 minus 413,000 = Tk 1,447,000
• Expense ratio: 413,000 / 1,860,000 = about 22%
• Vacancy loss: 36,000 / (1,296,000 + 600,000) = about 1.9% of potential rent

Net operating income is the figure most useful for comparing buildings and judging performance. Learn more in our explainer on what net operating income means for rental property. Note that this is a management figure; taxable income is calculated under tax law, which may allow or disallow certain items differently.

Tracking Dues and Collection Rate

Two simple numbers tell you how well rent collection is going:

• Collection rate = amount collected in the month / amount billed in the month x 100
• Total outstanding dues = all unpaid amounts across all tenants, grouped by age (0 to 30 days, 31 to 60 days, over 60 days)

For example (illustrative): In March you billed Tk 158,000 and collected Tk 146,000. Collection rate = 146,000 / 158,000 x 100 = about 92.4%. The Tk 12,000 gap should appear on your due list with each tenant's name.

Dues older than 60 days deserve special attention. The longer a due is left, the harder it is to collect.

Preparing for Income Tax

This is general information, not tax advice. Rental income is reported in your income tax return under the Income Tax Act 2023. The law provides for certain allowances or deductions against rental income, and rules on what can be claimed, required documents, withholding by corporate tenants and filing deadlines are updated through finance acts and NBR guidance. Good accounting makes the work of your tax lawyer or accountant much easier. At year end, have ready:

• Your rent roll and a yearly summary of rent received per unit.
• Expense summaries by category with receipts.
• Holding tax receipts.
• Loan statements showing interest, if applicable.
• Tax deduction certificates from corporate tenants, if any.
• Bank statements for the rental account.

Paper, Excel or Software?

Whichever you choose, the principles are the same: one place for each record, consistent categories, a receipt for every payment, and a monthly reconciliation.

Common Accounting Mistakes Small Landlords Make

• Mixing personal and rental money in one account or wallet.
• Recording security deposits as income.
• Not recording partial payments, then disputing balances later.
• Not keeping receipts for expenses.
• Treating major renovations as ordinary monthly expenses.
• Forgetting vacancy months when judging performance.
• Never reconciling the ledger with bank and bKash or Nagad statements.
• Waiting until tax time to organise the whole year's records.

Final Thoughts

Rental property accounting for small landlords comes down to a few steady habits: a separate account, four clear records, consistent categories, correct handling of advances and deposits, a monthly routine and a simple yearly summary. With these in place, you will know your real income, collect dues more reliably, prepare for tax with less stress, and make decisions based on facts.
