How to complete your Provestor property transactions spreadsheet

As part of your self-assessment tax return service, we need you to complete our rental income spreadsheet so we can accurately prepare your return. This guide explains exactly how to fill it in.

Download our spreadsheet template here

The spreadsheet is structured with a Summary tab and a separate tab for each of your properties. You only need to fill in the property tabs - the Summary tab is calculated automatically.

Step 1: Enter the Tax Year

At the top of each property tab, you'll see a Tax year field. Enter the tax year you are reporting for - for example, 2025/26.

Step 2: Fill In Your Property Details

Each property tab begins with two sections that help us understand your property and your tenants.

Property Details

Complete one row per property with the following information:

FieldWhat to enter
Property address & postcodeThe full address including postcode
Property typeE.g. flat, terraced house, semi-detached
No. BedroomsNumber of bedrooms
FurnishedYes or No
Date PurchasedWhen you bought the property
Purchase amountThe price you paid
Current valueYour best estimate of current market value
AgentsName of any letting agent managing the property (if applicable)
OwnersYour name, or all owners if jointly owned
Property splitIf jointly owned, the percentage split — e.g. 50/50

Property Tenants

Complete one row per tenancy. If you had more than one tenancy during the year (e.g. a change of tenant), add a row for each.

FieldWhat to enter
Move-in dateWhen the tenancy started
Renewal dateWhen the tenancy was last renewed (if applicable)
Ongoing renewal periodE.g. monthly rolling, 12 months
Rent amountThe monthly rent agreed
Tenant nameFull name(s) of the tenant(s)
Mobile numberTenant's contact number (optional)
Email addressTenant's email address (optional)
Deposit schemeThe name of the scheme used to protect the deposit

Step 3: Record Your Rental Income

The Payments section is where you record all money received and paid out during the year. Amounts are entered month by month, April through to March. The spreadsheet totals each row automatically.

Rental Income

Enter amounts in the relevant month column for the following rows:

RowWhat to include
Rent receivedThe rent paid by your tenant each month
Fees receivedAny other income received, such as application fees or admin charges

Pro Tip

Enter the amount actually received in the month it landed in your bank account. For example, if your tenant pays on the 1st of each month, enter it in that month's column.

Step 4: Record Deposits

Use the Deposit Payments section to record any deposits received or returned during the year. This is separate from rental income and is not taxable, but we need it for completeness.

RowWhat to include
Deposit receivedAny deposit paid to you by a tenant
Repayment of depositAny deposit returned to a tenant at the end of a tenancy

Note

If you deducted money from a deposit for repairs or unpaid rent, only enter the amount you actually returned to the tenant under 'Repayment of deposit'. Let us know in the notes if any deductions were made.

Step 5: Record Your Expenses

There are three expense sections, each broken down by month. Enter amounts in the relevant month column.

Mortgage & Repairs

RowWhat to include
Mortgage repaymentsThe full monthly mortgage payment (capital + interest)
Mortgage interest paymentsThe interest-only portion of your mortgage payment — check your mortgage statement if unsure
PaintingDecoration costs including painting and wallpapering
PlumbingAny plumbing repairs or callouts
ElectricalElectrical repairs, PAT testing, rewiring
AppliancesRepair or replacement of appliances such as white goods
Outside contractorsAny tradespeople not covered by the categories above
OtherAny other repair costs that don't fit the above

Note

Why we need both mortgage rows: Only the interest portion of your mortgage is tax-deductible (as a finance cost credit) — capital repayment is not. If you're unsure of the split, your lender's annual statement will show the breakdown.

Running Costs

RowWhat to include
Cleaning/maintenanceRegular cleaning, gardening, and general upkeep
GasGas bills paid by you as landlord (e.g. during void periods)
ElectricElectricity bills paid by you as landlord
WaterWater bills paid by you as landlord
Council taxCouncil tax paid by you (e.g. during a void period)
Letting / Management feesAny fees charged by a letting or management agent
OtherAny other running costs not covered above

Other Operating Expenses

RowWhat to include
AdvertisingCosts of advertising the property to find tenants
TV licencesAny TV licence you pay as landlord (e.g. furnished HMO)
OtherInsurance, EPC costs, gas safety certificates, legal fees, and anything else not covered above

Pro Tip

Not sure which category to use? Use the 'Other' row in the most relevant section and leave us a note. We'd rather you include something with a query than leave it out entirely.

Step 6: Repeat for Each Property

Complete tabs Property 1 through to Property 6 as needed - one tab per property. If you have fewer than six properties, simply leave the unused tabs blank.

The Summary tab will automatically total up figures across all properties. You don't need to edit it.

Common Expenses You Can Claim

Not sure what's claimable? Here are some of the most common allowable expenses for landlords:

  • Letting agent fees — including management and tenant-find commissions

  • Landlord insurance — including buildings insurance and rent protection

  • Repairs and maintenance — such as fixing wear and tear, gardening, and redecorating between tenancies

  • EPC and Gas Safety certificates — legally required and fully deductible

  • Advertising costs — to find tenants

  • Accountancy fees — your Provestor services are an allowable expense

For a full list, take a look at our complete guide to allowable property expenses on the Provestor help centre.
