What is catch up bookkeeping?
It’s a defined, time‑boxed clean‑up project to restore accurate, compliant accounts after falling behind. The goal is simple: get your books current, correct and ready for ATO reporting and decision‑making.
Unlike ongoing bookkeeping, catch‑up work often spans multiple months, requires error correction, and may involve preparing and lodging overdue BAS/IAS and fixing payroll/STP records.
Australian context to keep in view
- GST and BAS: Overdue BAS/IAS can attract penalties and interest. Only registered BAS or tax agents can lodge for a fee.
- Payroll and STP: Late or incorrect Single Touch Payroll reports can affect employee tax and super; super must be paid by due dates.
- Software: Xero, MYOB and QuickBooks can speed up reconciliation, but historical fixes still need careful review and documents.
- Year‑end: Accurate catch‑up makes tax returns faster and reduces accountant adjustments and costs.
What does catch up bookkeeping include?
Data and reconciliations
Import and reconcile bank/credit card feeds, match transactions, post missing entries, and clear suspense/miscoding.
GST and BAS checks
Review tax codes, fix GST on income/expenses, handle adjustments, and prepare overdue BAS/IAS for lodgement.
Sales and purchases
Enter missing customer invoices and supplier bills, match payments, and tidy aged receivables/payables.
Payroll and super
Correct earnings, leave, PAYG withholding and super; align STP submissions and year‑to‑date balances.
Balance sheet review
Check loans, asset purchases, director drawings, clearing accounts and opening balances for accuracy.
Documentation
Attach receipts, collect statements, and set up a simple “source docs” workflow to prevent future backlogs.
When do you need catch up bookkeeping— and how far back to go?
- You’re behind more than a few weeks and can’t trust your cash flow or profit reports.
- ATO has sent BAS/IAS reminders or your tax return is due.
- You changed software or bookkeepers and balances don’t tie out.
- Payroll/STP reports don’t match payslips or super hasn’t been reconciled.
Minimum scope is the entire period of any overdue BAS/IAS and the current financial year to date. Many businesses also catch up the prior year to ensure consistent comparatives and clean tax records.
How long it takes and what affects cost
Timelines range from a few days to several weeks. Key drivers are months of backlog, transaction volume, number of bank accounts and sales platforms, payroll complexity, and how quickly you can provide access and documents.
Pricing models vary: fixed fee per month caught up, hourly for discovery then fixed milestones, or a project price that includes BAS lodgements. Ask for a written scope, deliverables, timeline, dependencies and escalation plan.
What to prepare before you start
- Read‑only bank and credit card statements for the backlog period.
- Accounting software access (Xero/MYOB/QuickBooks) and payroll system access.
- Sales and e‑commerce exports (POS, Shopify, Stripe, PayPal, marketplaces).
- Supplier bills, receipts and asset purchase documents.
- ATO integrated client account reports, recent BAS/IAS, and payroll/STP summaries.
- List of loans, finance agreements, and director/shareholder drawings.
Who should do the work?
- Bookkeeper: day‑to‑day clean‑up, reconciliations, workflow setup and documentation.
- BAS agent: all of the above plus preparing and lodging BAS/IAS and GST adjustments for a fee.
- Accountant/tax agent: year‑end tax, complex structuring, and when cleanup affects tax positions.
If you need lodgements, use a registered BAS agent. For ongoing support once you are current, see bookkeeping services. For tax positions and year‑end planning, see the tax accountant hub.
Best next steps
Write down what’s overdue (months, BAS/IAS, payroll), gather bank statements and access, and decide whether you want a fixed project or phased milestones. Then contact a provider who can show their plan, not just their price.

Frequently asked questions
What Is Catch Up Bookkeeping?
It’s a one‑off project to bring overdue accounts current. Tasks include reconciling bank feeds, coding GST, entering missing bills/sales, fixing payroll/STP, reviewing balance sheet items and preparing any overdue BAS/IAS for lodgement.
When should I get professional help?
Get help when BAS/IAS are overdue, payroll or super has errors, you switched software/providers, or reports don’t match bank balances. Use a registered BAS or tax agent for any ATO lodgements.
How far back should I go?
Cover all overdue reporting periods at a minimum. Many businesses tidy the current and prior financial year for clean comparatives and simpler tax.
Will catch up bookkeeping remove ATO penalties?
Cleanup gets you compliant, but penalties/interest are at the ATO’s discretion. A BAS or tax agent can help request remission and manage timing.
Which software is best for catch up work?
Xero, MYOB and QuickBooks all work. The “best” choice is the one your provider knows well and that fits your volume, payroll and integrations.
