The dashboard tracks combined trading income across every stream and gives a plain-language prompt about whether HMRC may need to know.
UK Side Hustle Tracker
Log income, expenses and hours across every stream, track gross income against the trading allowance, estimate what to set aside and see what remains after costs and tax.

The actual dashboard, shown with example side-hustle records.
Income to take-home
Every entry updates the current tax year, the deduction comparison, the set-aside estimate and the result for each income stream.
The dashboard tracks combined trading income across every stream and gives a plain-language prompt about whether HMRC may need to know.
See income less actual costs and estimated tax, with a monthly set-aside figure for the next payment deadline.
Auto mode compares the trading allowance with recorded allowable expenses and uses the larger deduction for the estimate.
Group entries by hustle, record optional hours and compare profit share and what remains per hour after costs and estimated tax.
Filter and sort the tax-year entries, import or export CSV records, move several entries between streams and retain notes beside each amount.
Review income and expenses by stream, category and month, then print the annual recap or the separate SA103-shaped tax summary.
Compare the streams
The statistics page separates each stream so a larger turnover cannot hide high costs or a weak return on the hours spent.

One allowance, several conditions
The trading allowance relates to gross trading income from one or more trades. It can be used instead of deducting actual expenses when eligible. The app compares the figures you enter, but eligibility, registration and the final return still depend on your circumstances.
How it works
No installation, account or subscription is required.
Record the date, amount, type, stream and optional hours, with an expense category and notes where useful.
Add other annual income and choose the UK tax region so the estimate can place the side-hustle profit in context.
Review the year, print the tax summary and export CSV or JSON files for your own records or another Methodwise tool.
A connected tax workspace
Private by design
The tracker runs locally in your browser. It has no account, cloud database, analytics, bank feed or receipt upload, and it does not send income or expense records anywhere.
It does not register you for Self Assessment, file a return or provide tax advice. CSV and JSON transfers are manual files that you control. Keep regular backups somewhere separate from the downloaded app.
Frequently asked
It is designed for UK casual traders, freelancers and side-hustlers who want a manual income and expense log with an estimate of what to set aside. It is not a full bookkeeping, VAT or invoicing system.
No. The app combines the qualifying trading income entered across all streams because the allowance is considered at person level, not as a fresh allowance for every hustle.
No. The dashboard gives a trading-income prompt, but exceptions and other reasons for completing a return can still apply. Check the current GOV.UK guidance for your circumstances.
Not necessarily. The tracker is for trading income from work or items bought or made to sell. It does not classify sales of personal belongings, so check the official guidance if you are unsure.
It uses the income, expenses, other annual income and tax region you enter to estimate taxable profit, Income Tax and Class 4 National Insurance. The result is a planning figure, not a filed calculation or tax advice.
Yes. Give each entry a stream name and the dashboard and statistics will compare income, costs, profit and optional hours across them.
It works on Windows, Mac and Linux computers in a modern version of Chrome, Edge, Safari or Firefox.
