Your situation

Built for NZ's two most common rental setups

Fully rented out, or you live there with tenants — these are the two setups IRD treats differently. Zelvo knows the difference and applies the right rules automatically.

Fully Rented

Tenants in every room.
Simple as that.

When your property is fully rented out, every dollar of expenses is 100% deductible. No room setup needed. Zelvo applies a ratio of 1.0 — full deductibility, instantly.

What's specific to this setup
  • 100% rental ratio — no apportionment needed
  • No room builder required — log expenses and go
  • Full deductibility from day one of the FY
Rental Ratio
100%fully deductible
Flatting / Owner-Occupied

You live there too.
The IRD has a formula.

When you share the property with tenants, only a portion of expenses is deductible — based on floor area. IRD mandates a flat 50% weighting for shared/common areas. Zelvo calculates this exactly, room by room.

What's specific to this setup
  • Room-by-room builder with sqm dimensions
  • 50% weighting on common areas — IRD compliant (QB 25-01)
  • Rental ratio calculated automatically from your floor plan
  • Per-FY room snapshots when your layout changes
  • Tenancy tracking with date-weighted ratio adjustments

Income & Expenses

Every transaction, in one place.

Log rent received and every deductible expense as they happen. Zelvo applies your rental ratio automatically — so you always know exactly what's deductible without touching a calculator.

CSV bank import

Import months of transactions in one go. Zelvo auto-categorises based on description and learns from your corrections.

Recurring templates

Set up mortgage repayments, rates, and rent once. Generate the whole year's transactions in seconds.

Receipt storage

Attach receipts to any transaction. Everything IRD might ask for, filed in the right place.

Fiscal year scoping

All transactions are scoped to the NZ fiscal year (Apr–Mar). Switch years without losing any data.

Deductions you might be missing

Two deductions most landlords forget to claim.

Chattel depreciation and mileage are legitimate, IRD-approved deductions. Most landlords skip them because the tracking is tedious. Zelvo makes both effortless.

Chattel Depreciation

Every appliance and fitting
is worth something.

The dishwasher, the heat pump, the carpet — all depreciable. Record each chattel with its cost and IRD depreciation rate. Zelvo calculates the annual deduction and applies your rental ratio automatically.

  • Investment Boost — extra 20% first-year deduction on new chattels bought on or after 22 May 2025 (NZ Budget 2025), applied automatically
  • Capital improvements — upgrades tracked as separate additions, each depreciating from its own date

DishwasherDV 30%$198
CarpetSL 17.5%$156
CurtainsDV 25%$94
Total deductible$880

Mileage Tracking

Every trip to the property
is a deduction.

Inspections, repairs, tradespeople meetings — every kilometre driven counts. Log the trip, Zelvo looks up the IRD rate for your vehicle type and fiscal year, and calculates the deduction automatically.

Joint OwnershipZelvo Exclusive

Own it together. File separately.

If you co-own a rental property, each of you must declare your proportional share on your own IR3 — not a combined figure. This trips up couples every single year.

Zelvo splits every figure by ownership percentage in real time. Each owner gets their exact gross income, deductible expenses, and net income — ready to file. Nothing else in NZ does this.

IRD Filing Guide

Know exactly what to enter, where.

myIR is not intuitive. Zelvo includes a step-by-step filing guide built right into the app — with your real figures, so you're not guessing which number goes where.

Filing deadline — 7 July

Individuals must file their IR3 by 7 July each year. Zelvo reminds you in the app. If you use a tax agent, their deadline may differ.
