What your accountant actually needs at tax time
Accountants rarely need more documents. They need the same documents in a state where they can start work without asking you eleven follow-up questions.
The short checklist
For most sole traders and freelancers the handover comes down to five things: a complete record of income, a categorised list of expenses, receipts substantiating the larger or less obvious ones, details of any assets bought or sold during the year, and last year’s return as a reference point.
What separates a smooth handover from a slow one is rarely a missing item. It is usually that the expenses arrive uncategorised, so the first thing your accountant does is work that you could have had done automatically.
Why categorisation is the bottleneck
A raw bank export is a list of merchants and amounts. Turning that into a return means deciding, line by line, which entries are business, which are personal, and which are claimable — and your accountant has to ask you about anything ambiguous.
Every one of those questions is faster to answer in the moment than eleven months later. Categorising as transactions arrive means the ambiguities get resolved while the context is still fresh, and your accountant receives decisions rather than questions.
Substantiation: attach, do not append
Receipts sent as a separate folder create reconciliation work — someone has to match each one to a line. Receipts already attached to their transactions arrive pre-reconciled, and the gaps are visible at a glance.
This matters most for the expenses an accountant is likely to query: larger one-off purchases, anything with a mixed business and private use, and merchants whose name gives no clue about what was bought.
Hand over once, not in instalments
The slowest handovers are the ones that happen in pieces — an export, then a follow-up email of receipts, then a correction. A single tax-ready export containing categorised transactions, a deduction summary, a GST breakdown where relevant and the attached receipts collapses that into one exchange.
It also makes the year auditable in the ordinary sense: if a figure is ever questioned, the record supporting it is already sitting beside it rather than needing to be reassembled. This is general information, not personal tax advice — check what applies to you with your accountant or the relevant tax authority.
Common questions
What documents should I give my accountant?
Income records, a categorised expense list, receipts for larger or less obvious purchases, details of assets bought or sold, and your previous return. Providing expenses already categorised is the single change that most reduces back-and-forth.
How far in advance should I get organised?
The work is easiest when it is spread across the year rather than compressed into the weeks before lodgement. If transactions are categorised as they arrive, there is no preparation period — the export is ready whenever you are.
Should I categorise transactions myself, or leave that to my accountant?
Categorising as you go is usually both cheaper and more accurate. Accountants bill for time, and sorting a year of raw bank lines is slow work; more importantly, you are usually best placed to explain why a particular payment happened, and that context fades fast. Hand over decisions rather than questions and their time goes to structuring and lodgement instead. This is general information, not personal tax advice — check what applies to you with your accountant or the relevant tax authority.
