Talk to enough accountants — which, building a tool in this space, I've had occasion to — and you notice something: their wishlist for clients is remarkably consistent, and remarkably short. It's not "learn double-entry bookkeeping." It's a handful of small habits that, if you'd done them through the year, would turn a stressful, expensive filing into a quick one.
None of this is exotic. But hearing it from the people who actually prepare your return is more persuasive than any app pitch, so here's the consolidated version of what they wish you'd do.
Keep a separate business bank account
This is the one almost every accountant names first. When business and personal spending share an account, someone — usually them, on your dime — has to comb through and separate the two, line by line. A dedicated business account makes most of your records self-sorting: money in is income, money out is (largely) business expense. It's the single highest-leverage thing you can do, and it costs you nothing but an afternoon to set up.
Capture receipts as they happen
The reconstruction problem is what accountants dread. A client who tries to rebuild a year of expenses in March from bank statements and memory will miss things, guess at others, and hand over a muddle. Receipts captured as they happen — photographed at the till, saved when the email invoice arrives — are legible, complete, and dated correctly. Thermal paper fades; a photo taken in the moment doesn't. This is the habit that prevents the shoebox before it forms.
Don't commingle — keep entities separate
If you run more than one venture, or a job plus a side business, keep their records apart from the start. Blended books force your accountant to disentangle which expense belonged to which, and make it impossible for anyone to see whether each venture is actually making money. Separate accounts, separate folders, separate from day one. (We went deep on why this matters — and how the tax rules force it — in the multiple-businesses post.)
Reconcile monthly, not annually
A year is too long to remember what a payment was for. Accountants would much rather you spent thirty minutes a month matching receipts to bank transactions than save it all for one heroic, error-prone session at year-end. Monthly reconciliation catches mistakes while they're fresh and fixable, and means nothing's a mystery by the time the return is due.
Hand things over organised, and once
The trickle is its own special pain: receipts arriving by email, then WhatsApp, then "oh, and one more" over three weeks. What accountants want instead is everything in one place, delivered once — legible images, consistently named, with a summary they can reconcile against your bank statements. A single organised package answers most of their questions before they ask them. (That end-to-end handover is exactly what the shoebox-to-accountant workflow walks through.)
Bring your questions early
Accountants are at their most rushed right before the deadline — which is, of course, exactly when most clients surface. If you have a judgment call (is this expense claimable? which scheme should I be on?), raise it weeks ahead, when they have time to think it through properly rather than triage it. Early questions get better answers.
Keep your records for the years required
Filing isn't the end of the obligation. Tax authorities can come back years later, and retention requirements typically run to six or seven years depending on where you are. Accountants wish more clients understood that the records need to survive that long, in a findable form — not get deleted the moment the return is filed, or buried in a drawer where no one could produce a specific invoice three years on.
The thread running through all of it
Notice what every item has in common: a little, done regularly, instead of a lot, done in a panic. Accountants aren't asking you to become a bookkeeper. They're asking you to capture as you go, keep things separate, and hand over something organised — so that the expertise you're paying for goes into your actual return, not into sorting your paperwork. Clients who do that pay less, file faster, and field fewer anxious questions. It's the closest thing to a free lunch tax season offers.
