Doing your own taxes when you are self-employed in the UK starts with clear records. The aim is not to guess your tax bill in January, but to keep income, expenses, receipts and mileage organised throughout the year so Self Assessment is easier to review.
Keep income records in one place
Track every invoice, payment and income source with dates, customer names and amounts. If you use more than one platform or payment provider, export the records regularly so your bookkeeping stays complete.
Track expenses as you go
Record business costs when they happen instead of rebuilding them later. Keep receipts attached to each expense and separate personal spending from business spending.
Common records to keep include:
- software and subscriptions used for business
- office, phone and internet costs
- travel and mileage records
- professional fees
- subcontractor or supplier invoices
Reconcile records before Self Assessment
Before using figures for Self Assessment, compare invoices, payment records, receipts and bank exports. Look for missing receipts, duplicate entries, unpaid invoices and personal costs that should not be treated as business expenses.
Set money aside during the year
Self-employed tax planning is easier when you review profit regularly and set money aside before the deadline. LedgerlyPro can help organise records and estimates, but you remain responsible for checking figures before submitting anything to HMRC.
Prepare before submitting to HMRC
When your records are tidy, Self Assessment usually becomes a review task rather than a rescue job. Export your income, expenses, mileage and receipt records, then check them against HMRC guidance or with an accountant for your situation.
