Business Income & Expense Tracker

This is the tool the self-filing checklist assumes you already have somewhere: a running log of what came in and what went out, so that when a VAT or CIT deadline arrives, you’re pulling a number from a total you’ve been keeping all along — not reconstructing a year of bank statements the night before it’s due.

Filter by Period, Then Export

Set a date range before exporting to get exactly the period you need — a calendar month for VAT, a full financial year for CIT — rather than your entire history every time. Leave both dates blank to see and export everything.

Choosing an Export Format

CSV opens in anything — Excel, Google Sheets, accounting software — and is the safest choice if you’re not sure what the next step needs. Excel (.xlsx) keeps the same data with column formatting already applied. PDF is a fixed, shareable snapshot — good for handing to someone else or keeping as a dated record, not for further editing.

Where This Feeds Into Your Actual Tax Figures

Your net profit for a period is the starting point for the CIT calculator‘s assessable profit figure and the annual tax planner‘s business forecast. Your income entries are also what a VAT calculator run needs for net sales. This tool doesn’t calculate tax itself — it keeps the numbers those calculators need in one place.

Frequently Asked Questions

Where is my income and expense data stored?

Only in this browser’s local storage on this device — never sent anywhere. Export a copy if you need it elsewhere.

Which export format should I use for filing?

CSV or Excel for further editing or handing to an accountant; PDF for a fixed, shareable record.

Does this calculate my tax for me?

No — it tracks income, expenses, and net profit. Feed those figures into the CIT, VAT, or income tax calculators for the actual tax computation.

This tool stores data only in your browser’s local storage — clearing your browser data or switching devices means starting fresh unless you’ve exported a copy. It does not calculate tax, file anything, or connect to any tax authority system.
