A financial operations platform that only works in one country is not a platform for growing businesses. Mid-market companies expand across borders, hire internationally, and increasingly serve customers in multiple markets. When that happens, their accounting and tax obligations follow them. The software they use should follow them too.
Monesize Core now includes native support for Irish VAT reporting and Australian GST reporting, sitting alongside the existing UK, US, and Canadian tax modules. All of them live in the same platform. All of them read from the same transaction data. None of them require a separate subscription, a third-party integration, or a spreadsheet to bridge the gap.
This article explains how both modules work and what they cover.
Ireland: filing the VAT3 return without leaving the platform
Ireland uses a value-added tax system administered by Revenue, the Irish tax authority. The standard rate is 23%. Ireland also applies reduced rates of 13.5%, 9%, and 4.8% to specific categories, with zero-rated and exempt supplies on top of that. Businesses registered for Irish VAT must file a VAT3 return for each filing period, typically bimonthly, with quarterly and annual options available at lower revenue thresholds.
The VAT3 return has nine fields. Monesize Core computes all of them automatically from the transaction data already in the system.
T1 captures total output VAT on domestic sales. The module reads all invoices and direct sales for the period with tax type set to VAT and sums the tax amounts, excluding intra-EU supplies which are reported separately.
T2 captures total input credit. This is the VAT the business paid on purchases, expenses, and bills during the period, which it can recover from Revenue.
T3 is the net VAT payable, T1 minus T2 when positive. T4 is the net VAT repayable, T2 minus T1 when positive. Only one of the two will have a value in any given period.
E1 and E2 handle intra-EU trade. E1 captures the value of goods supplied to VAT-registered buyers in other EU member states, zero-rated under EU rules. E2 captures the value of goods acquired from EU suppliers. Both fields use the EU transaction flag already available on every invoice and sale in the platform, so businesses already tagging their cross-border transactions correctly will see these fields populate automatically.
ES1, ES2, and PA1 cover electronically supplied services and postponed accounting on imports. These default to zero in the current implementation and are available for manual adjustment by the finance team.
The workflow is straightforward. The finance team selects a filing period and the system builds the return immediately. They can review every line, add manual adjustments where needed, recalculate at any time to pick up late transactions, mark the return as ready when they are satisfied, and record the Revenue confirmation reference after filing through Revenue Online Service.
To set up the module, a general administrator enters the organisation’s Irish VAT number in Organisation Settings. The format is the IE prefix followed by seven to nine alphanumeric characters, for example IE1234567T. The platform validates the format on save.
Australia: lodging the BAS without a tax agent portal
Australia’s GST is a flat 10% on most goods and services. There are no reduced rates. GST-free supplies such as exports and basic food, and input-taxed supplies such as financial services and residential rent, carry a zero rate with specific rules around input tax credit treatment. The flat structure makes the Australian module the simplest of the tax modules in the platform.
The Business Activity Statement is the return that Australian businesses lodge with the Australian Tax Office on a monthly, quarterly, or annual basis. The GST section of the BAS tracks total sales figures, total purchase figures, the GST collected on sales, and the GST credits claimable on purchases.
G1 is total sales including GST. The module sums the total amount on all GST-type invoices and direct sales within the period.
G2 and G3 capture export sales and other GST-free sales. These default to zero and are available for manual adjustment, covering businesses that need to report their GST-free supply split to the ATO.
G10 captures total capital purchases including GST. G11 captures total non-capital purchases including GST, drawn from expenses and bills paid during the period.
1A is the GST collected on sales. This is the 10% tax component on invoices and direct sales.
1B is the GST credits on purchases. This is the 10% tax component on purchases, expenses, and bills, which the business can claim back.
Net GST is 1A minus 1B. When positive, the business remits that amount to the ATO. When negative, the ATO owes a refund.
The same workflow applies. The finance team selects the BAS period, the system builds all fields, they review and adjust if needed, mark as ready, lodge manually through ATO online services or their registered tax agent, and record the ATO reference number in the platform.
To configure the module, a general administrator enters the organisation’s Australian Business Number in Organisation Settings. The ABN is an eleven-digit number issued by the Australian Business Register. The platform validates the format on save.
Manual adjustments on both returns
Both modules support manual adjustments on any editable return field. The finance team can add an adjustment with a field name, an amount, and a reason before marking the return as ready. Common uses are bad debt relief, corrections for transactions that crossed period boundaries, and entries for fields the system defaults to zero.
When a return is recalculated to pick up new transactions, saved adjustments are automatically re-applied on top of the fresh aggregation. The team does not need to re-enter them.
The live summary view
Both modules include a summary view that shows all return fields for any date range without creating a return record. The finance team can use this for mid-period checks, to see where the net tax position is tracking, whether input credits are being captured correctly, and whether any figures need investigation before the filing period closes.
How it fits into the rest of the platform
Neither module required any changes to how the platform handles invoicing, sales, purchasing, or expenses. The transaction data was already there. The tax type field already existed on every transaction. The return aggregation simply reads what is already in the system and maps it to the correct form fields.
For Ireland, transactions use tax type VAT, the same as UK transactions. Both countries’ reporting modules aggregate from VAT-type transactions independently. A business that files in both the UK and Ireland using Monesize Core handles both obligations from the same platform with no duplication of data and no cross-contamination between the two returns.
For Australia, transactions use tax type GST, the same as Canadian transactions. The same independence applies.
The journal entries, balance sheet, income statement, and all other accounting outputs are unaffected. Tax reporting is a read operation on existing transaction data. It adds no new data entry burden to the day-to-day workflow.
Where Monesize Core now stands for tax coverage
Monesize Core currently handles tax compliance for five English-speaking markets in a single platform.
United Kingdom: nine-box VAT return with direct Making Tax Digital submission to HMRC.
United States: proprietary sales tax engine with state-level rate calculation, nexus management, category exemptions, and per-state liability reporting.
Canada: GST/HST return with all eleven GST34 fields computed from transaction data.
Ireland: VAT3 return with all nine fields including intra-EU supply and acquisition reporting.
Australia: Business Activity Statement with G-series totals, 1A output tax, 1B input credits, and net GST.
All five share the same transaction data. All five use the same return lifecycle. None of them require a third-party subscription or a separate system.
What is coming next
Direct digital filing integration with Revenue’s Online Service for Ireland and with the ATO’s Standard Business Reporting system for Australia are planned for future releases. The current implementation produces complete, accurate returns that finance teams lodge manually through the authority’s own portals. The confirmation reference is recorded in Monesize Core after lodgement, giving a full audit trail without any manual data entry back into the platform.
Monesize Core is a modular financial operations platform built for mid-market businesses. Irish VAT and Australian GST reporting are available on all plans for the respective jurisdiction deployments.
