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.
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.
- ✓100% rental ratio — no apportionment needed
- ✓No room builder required — log expenses and go
- ✓Full deductibility from day one of the FY
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.
- ✓Room-by-room builder with sqm dimensions
- ✓50% weighting on common areas — IRD compliant
- ✓Rental ratio calculated automatically from your floor plan
- ✓Per-FY room snapshots when your layout changes
- ✓Tenancy tracking with date-weighted ratio adjustments
Your IR3 figures, calculated.
Open the Tax Report and everything is there — gross income, deductible expenses broken down by category, depreciation, mileage, and net rental income. Formatted exactly as IRD needs it.
Hand the report to your accountant, or paste the figures directly into myIR yourself.

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.
Upload the statement you get from your property manager and Zelvo parses every row — rent received, management fees, GST, R&M charges — ready to review before import.
Import months of transactions in one go. Zelvo auto-categorises based on description and learns from your corrections.
Set up mortgage repayments, rates, and rent once. Generate the whole year's transactions in seconds.
Attach receipts to any transaction. Everything IRD might ask for, filed in the right place.
Zelvo flags likely duplicates on every import so you never book the same rent or expense twice.
All transactions are scoped to the NZ fiscal year (Apr–Mar). Switch years without losing any data.
Two deductions that are easy to miss.
Chattel depreciation and mileage are legitimate, IRD-approved deductions — often missed because the tracking is tedious. Zelvo makes both straightforward.
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.
- ✓Low-value asset write-off — chattels costing $1,000 or less are automatically written off in full in the purchase year (IR264)
- ✓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
- ✓Change of use — chattels introduced from private use depreciate from their market value on the rental-start date

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.
No 90-day logbook required. Zelvo uses the kilometre-rate method — each trip you log is your substantiation. The 14,000 km Tier 1 cap and Tier 1/2 pro-rata split are handled automatically from your annual odometer readings.

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. It's one of the easiest things to get wrong.
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.
Know exactly what to enter, where.
myIR can be hard to navigate the first time. 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.
- ✓IR3R line-by-line card — every IR3R field (Rates, Insurance, Interest, Agent's fees, R&M, Depreciation, Vehicle, Legal, Other) populated with the exact $ amount you enter
- ✓Income split by IR3R line — Gross rents on one line; rebates, insurance payouts, and expense reimbursements routed to "Other rental income" per IR3R Note 2
- ✓Prior-year loss reminder — Q22 Brought Forward Losses (Box 22F on 2026 form) with the dollar amount already scaled to your ownership share
- ✓Ring-fencing guidance — full rentals stay on Q22; main-home flatting goes on Q23 — Zelvo labels each correctly
- ✓Per-owner auto-scaling — every figure already reflects your ownership percentage — no mental maths for joint ownership
- ✓5-step myIR walkthrough — with your personalised figures, not a generic checklist
- ✓Documents checklist — so you know what to have on hand before you start

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.
Catches the niche rules most landlords don't know about.
Zelvo applies the specific IRD rules behind each number, line by line.
Capital vs repair classifier
R&M entries over $1,000 prompt a 3-question IRD test. Capital items are routed to the chattel flow or a building improvement record — not deducted as R&M by mistake.
Low-value asset write-off
Chattels costing $1,000 or less are fully deducted in the purchase year. Shown as a separate line on the Tax Report so you can see exactly what qualified.
Legal fees $10k cap
Purchase/sale legal fees are deductible only if your total across every property in the year is ≤ $10,000. Zelvo aggregates across your properties and flags if you cross the threshold.
Rebates go on Other rental income
Insurance payouts, rates refunds, and expense reimbursements are taxable income — not negative expenses. Record them as income; Zelvo puts them on the right IR3R line automatically.
Prior-year loss reminder
When the prior FY ended with a ring-fenced loss, Zelvo surfaces the carry-forward dollar amount and points to the exact box on IR3 — scaled to your ownership share.
Anti-splitting nudge on LVA bundles
If you try to log two low-value assets on the same date (e.g. a whiteware package), Zelvo reminds you that IRD treats bundled purchases as a single asset — preventing an accidental over-claim.
