MTD Record-Keeping Checklist

Record the amount for each income entry

Keep a clear value for each sale, payment, or rent amount you need to track.

Record the date for each income entry

Dates matter for keeping your records in order and reviewing each period properly.

Use a clear category or source label

Separate income types so your records stay organised and easier to review later.

Keep self-employment and property income clearly separated where relevant

That makes the records easier to follow if you have more than one source.

Record the amount for each expense

Keep each amount entered clearly rather than waiting until later to estimate it.

Record the date for each expense

This helps keep your records in the right order through the tax year.

Use clear expense categories

Grouping expenses properly makes your records easier to understand and maintain.

Keep business and private spending separate

Mixing personal and business spending makes the record-keeping process harder later.

Keep receipts, invoices, or other supporting evidence where relevant

Supporting records make it easier to check entries later if something needs reviewing.

Keep payment references or notes where useful

Short notes can make unusual or one-off entries easier to understand later.

Keep your records digitally rather than relying on loose paper notes

The aim is to keep your system consistent and usable through the year.

Update records regularly rather than leaving everything until the last minute

A simple routine is usually easier than a large catch-up at the end.

Choose a digital system or software approach you can actually keep up with

The best setup is one you will use consistently, not one that looks complicated.

Know the quarterly update rhythm for the year

Deadlines are easier to manage when you understand the pattern early.

Review your records before each reporting point

Regular checks reduce the risk of rushed or confusing catch-up work later.

Keep records usable for year-end finalisation as well as quarterly updates

The year-end stage still matters, so your records need to stay usable beyond each quarter.
