Question 1

What does the expense categoriser do?

Accepted Answer

It reads your Irish bank statement CSV, finds every outgoing payment (your expenses), and automatically sorts each one into a landlord expense category — maintenance, insurance, utilities, mortgage interest, RTB fees, and more. Each category is tagged with an indicative Irish Case V tax-treatment hint so you can see at a glance what is typically deductible against rental income.

Question 2

Which banks are supported?

Accepted Answer

We currently support AIB, Bank of Ireland (BOI), and Revolut CSV formats, with more on the way. Each bank exports CSV statements slightly differently — our processor normalises them automatically. For a direct Open Banking connection, TenantSync supports all major Irish banks.

Question 3

How accurate is the categorisation?

Accepted Answer

It uses the same Smart Expense Engine that powers TenantSync's open-banking expense tracking, built around an Ireland-focused keyword map (Electric Ireland, Bord Gáis, FBD, RTB, LPT and more). Anything it can't confidently match is flagged as “Review” so you can re-classify it yourself. Treat the results as a fast first pass, not a finished tax return.

Question 4

Is the tax-treatment hint tax advice?

Accepted Answer

No. The deductible / capital allowance / not-deductible labels are general guidance for Irish Case V rental income only and are not tax advice. Allowable expenses depend on your circumstances — always confirm with Revenue or your accountant before filing your Form 11.

Question 5

Is my bank statement stored or shared?

Accepted Answer

No — your CSV is processed in real time and immediately discarded after the preview is generated. We do not store, log, or retain any of your bank statement data. The tool is a stateless, non-persistent preview.

Question 6

How do I export a CSV from my bank?

Accepted Answer

AIB: Internet Banking → your account → Export / Download transactions → CSV. Bank of Ireland: 365 Online → your account → Download Transactions → CSV. Revolut: app → account → Statement → CSV (Excel). Choose the date range you want to analyse before downloading.

Question 7

Can I get the breakdown emailed to me?

Accepted Answer

Yes. After you run the analysis you can have the summary emailed to your inbox so it is ready when you prepare your return — and optionally get a start-of-month nudge to categorise the new month’s expenses.
