Best Trading Journal for NZ Traders: IRD-Compliant Picks for 2026

If you're looking for the best trading journal as a NZ trader, you've probably noticed that most recommendations come from overseas forums and point to software built for Americans filing with the IRS. That doesn't help much when your tax year ends on 31 March, your trades span forex, shares, crypto and metals, and every one of them needs reporting to IRD in New Zealand dollars. This guide judges trading journals on what matters here: NZ tax, the brokers Kiwis actually use, and whether you'll keep using it after the first month.

Why Most Trading Journal Recommendations Don't Work for New Zealand Traders

Most of the best-known trading journals were built for US traders. They default to a calendar tax year, report in USD and produce tax summaries shaped around IRS forms. None of that matches what IRD needs: NZD figures, a 1 April to 31 March year, tax at your marginal rate on top of your other income, and losses that can carry forward indefinitely.

Search for a NZ trading journal and you'll mostly find Reddit threads and Facebook posts. That tells you something. Kiwi traders are asking each other what works because the product pages don't speak to their situation.

Most "best of" lists also skip the brokers New Zealanders actually use. MT4, MT5, cTrader, OANDA, CMC Markets and IG are standard here, yet plenty of journals expect you to export and reshuffle columns by hand. That's hours a month a proper importer should save you.

And a journal that can't tell you whether you'll owe provisional tax next year is missing one of the most common surprises for NZ traders who've had a good year.

What a Trading Journal Must Do for NZ Traders (Beyond Basic P&L Tracking)

IRD-Ready Tax Reporting as a Core Feature

A journal should give you, or your accountant, a structured report of realised gains and losses by asset class and tax year. A raw CSV dump that has to be rebuilt from scratch doesn't count. The detail matters because IRD's rules differ by asset: forex and CFDs fall under the financial arrangements rules, shares are taxed according to why you bought them, and overseas shares can bring in the FIF rules.

The tax estimate needs to use the actual NZ brackets applied to your total income, not a flat percentage. If you're in the 33% bracket and the journal assumes a flat 28%, your estimate and your provisional tax planning will both be wrong.

Loss carry-forward tracking is non-negotiable. NZ losses can carry forward indefinitely, but you need to show which year each loss came from, how much has been used and what's left. Without that trail you risk losing a deduction you were entitled to. Loss carry-forward for NZ traders explains how it works.

NZD Reporting and RBNZ Rates

Any journal claiming to serve NZ traders has to convert foreign-currency trades into NZD with a consistent, verifiable rate. RBNZ rates are the obvious choice because they're independent and easy for IRD to check. Mixing broker rates with whatever spot price was handy creates discrepancies that are hard to defend.

Seeing your P&L in NZD as you go also avoids nasty surprises. A trade that looks profitable in USD can turn into a loss once the exchange rate moves. Knowing your NZD position means you're making decisions on what you'll actually bank.

If you trade USD, AUD, EUR or GBP accounts, the journal should convert each one automatically. Anything less is spreadsheet work you're paying software to avoid.

Broker Imports for NZ-Available Platforms

Manual entry wastes time and causes errors. A good journal imports directly from MT4, MT5, cTrader, OANDA and the other brokers NZ traders use, by file or API, without making you reformat columns or fix date formats first.

The importer should also catch problems: duplicate trades, missing commissions, a currency it's guessing at. Fixing those at import stops them flowing into your tax figures.

Free vs Paid Trading Journals: What You Actually Get for Your Money

Free options like spreadsheets, basic web apps and your broker's own reports are fine if you only make a handful of trades a year. Beyond that, manual entry and the lack of tax formatting make them hard to keep up. You'll spend more time maintaining the spreadsheet than you saved by not paying for software.

Paid journals typically cost somewhere between NZ$15 and NZ$50 a month. Price isn't really the difference. What matters is whether the tool understands NZ tax or just offers a generic "tax report" that still needs reworking before your accountant can use it. A US-shaped report is barely better than a spreadsheet, whatever it costs.

Use the free tier or trial properly. Load a real sample of your own trade history, not demo data, and see how it handles NZD conversion and your broker's quirks before you pay. Watch for hidden costs too: NZD reporting locked behind a premium tier, per-broker fees, or export limits that force an upgrade mid-year.

How to Evaluate a Trading Journal for Your Specific Trading Style

For Forex and CFD Traders

Forex journals need to handle swap and rollover charges, different lot sizes and partial closes. These are everyday MT4 and MT5 events that share-focused journals often get wrong. If swap costs aren't tracked properly, your P&L drifts further from reality every month.

The journal should also show risk as a percentage of your account, not just in dollars. A $500 loss means something very different on a $5,000 account than on a $50,000 one.

Automatic MT4 and MT5 import is essential. Typing in 200 forex trades a month by hand isn't sustainable, and the errors defeat the point of keeping a journal. For the tax side, see how forex trading is taxed in NZ.

For Share and ETF Traders

Share journals need to handle NZX, ASX and US stocks together, record dividends correctly and cope with splits and other corporate actions. Get those wrong and the cost of your shares, and so your taxable gain, is wrong too.

If you buy the same share in several parcels, the journal needs a consistent way to decide which parcel you sold. Pick a method and stick with it. Switching partway through creates a mess your accountant will charge to untangle.

Overseas shares need extra care. If the total cost of your overseas shares goes over $50,000 at any point in the year, the FIF rules generally apply instead. A good journal helps you see when you're getting close. See FIF tax in NZ.

For Crypto Traders

Crypto is where journals differ most. If you trade crypto CFDs or on a platform that reports realised profit per closed trade, a journal can work from those figures directly. If your history is spot buys, wallet transfers and on-chain swaps, someone has to match each sale to the coins it came from, and that takes cost-basis tracking across every exchange and wallet. A transfer between your own wallets isn't a disposal, but it still needs recording.

Don't expect a journal to split crypto into short-term "trading" gains and tax-free long-term holds. For most people in NZ, crypto bought to sell later is taxable whenever it's disposed of, however long it was held, and swapping one coin for another counts. See crypto-to-crypto tax in NZ.

Staking rewards, airdrops and DeFi transactions are common now and hard to track by hand. If your crypto goes beyond simple trades, check the tool handles them. DeFi and staking tax in NZ covers how they're taxed.

For Accountants Reviewing a Trader's Records

Accountants need a clean report with a clear audit trail, not raw data to reconstruct. It should show the working, the loss carry-forward position and a breakdown by asset class.

A read-only share link lets an accountant review a client's trades without logging into their account or swapping spreadsheets by email. That's better for security and saves everyone time.

Our Pick for NZ Traders: TradeLog NZ

Yes, it's ours. We built TradeLog NZ because nothing else did the NZ side properly. Here's what it does, and where it doesn't fit, so you can judge for yourself.

It imports from MT4, MT5, cTrader (including Pepperstone), OANDA, CMC Markets, IG, Interactive Brokers and TradingView, and OANDA and cTrader accounts can sync automatically. Every trade is converted to NZD at the RBNZ rate. The tax report applies the NZ brackets to your total income, adds the ACC levy where it applies, flags provisional tax, keeps a loss carry-forward ledger across years and shows the working line by line.

The journal side covers tags, a plan and post-trade review for each trade, screenshots, a daily recap and a trading calendar. Pro adds edge analytics: performance by time of day, holding time and tag.

The Free plan covers your first 30 trades and includes the tax report view. Starter is $19 a month or $190 a year for unlimited trades and file import. Pro is $39 a month or $390 a year and adds the accountant-ready PDF, a read-only accountant share link, past tax years, broker auto-sync, AI insights and edge analytics.

Where it isn't the right tool: TradeLog NZ works from the realised profit or loss your broker reports on each closed trade. It doesn't do lot-by-lot cost-basis matching for raw wallet and on-chain crypto history. If that's most of your activity, our guide to the best trading tax software in NZ explains what else you'll need. For more on the AI and automation side, see AI trading journal NZ.

Beyond the Journal: What Your Trading Workflow Actually Needs

A journal is one part of a bigger setup that includes your broker, your risk rules and your tax. The best one fits into how you already work instead of adding another login and another export to your week.

Provisional tax forecasting should come straight from your trade history. If the tax left to pay at year end tops $5,000, you'll generally owe provisional tax in instalments the following year. A journal that estimates that from your actual results helps you set money aside before the bill arrives. See provisional tax for NZ traders.

GST is one thing you can mostly stop worrying about. Profits from trading forex, shares and metals are exempt from GST, crypto sits outside it altogether, and none of it counts toward the $60,000 registration threshold. It only comes into play if you also sell something taxable, like a course or a signals service. GST for traders in NZ has the detail.

Business status is worth understanding early. Whether IRD sees your trading as a business affects whether a loss can reduce the tax on your salary in the same year, and whether ACC levies apply. A journal can show you how your activity looks against the factors IRD considers, but the decision is yours to make with your accountant. Read business trader or passive investor? for how IRD draws the line.

Ideally one platform handles the import, the NZD conversion, the tax figures and the report. Four separate tools that don't talk to each other just create reconciliation work.
