How long does a BAS catch-up take?

For 1–2 outstanding BAS, expect around 2–5 business days once we receive access and records. For 3–8 quarters, allow 1–3 weeks depending on bookkeeping quality, payroll corrections and documentation turnaround.

How much do bas catch up services cost?

Fixed-fee quotes start around $450 per straightforward BAS period. Backlog packages for multiple quarters commonly range from $1,200 to $4,500+. Payroll or superannuation corrections, missing-document rebuilds and software migrations are priced separately after review.

Will I get penalties for late BAS?

The ATO may apply Failure to Lodge (FTL) penalties and General Interest Charge (GIC). We help you minimise exposure by lodging quickly, correcting errors, and requesting penalty and interest remission where eligible. If you cannot pay in full, we assist with ATO payment plan requests.

Do I need a registered BAS agent?

Working with a registered BAS agent is recommended for preparing and lodging BAS on your behalf. Registered agents access the ATO agent portal, understand GST/PAYG rules and lodgement deferrals, and can help you navigate penalty remission processes.

Q: What do bas catch up services include?

Typical scope includes bank and payroll reconciliations, fixing GST codes, reviewing BAS settings, preparing outstanding BAS, lodging with the ATO, and setting up a payment plan if needed. We also put controls in place to stop the backlog returning.

How bas catch up services usually work

A practical bas catch up workflow focuses on speed, accuracy and communication. Here is the typical path:

Step 1 — Rapid triage: confirm your business structure, BAS cycle (monthly or quarterly), overdue periods, software and deadlines.
Step 2 — File review: check GST/PAYG settings, chart of accounts, tax codes and bank feeds; agree scope and a fixed-fee quote.
Step 3 — Reconcile: bring bank, sales, bills and payroll to the reporting date; fix obvious GST coding errors.
Step 4 — Prepare BAS: compile BAS workpapers, explain variances and obtain sign‑off.
Step 5 — Lodge & ATO: lodge each overdue BAS, request penalty/interest remission where appropriate and set up a payment plan if needed.
Step 6 — Prevent repeat: adjust processes, automate documents, and set reminders so lodgements stay current.

Talk to a registered BAS agent

Australian context to keep in view

BAS is used to report GST, PAYG withholding and other activity statement obligations to the ATO. Most small businesses lodge quarterly; some lodge monthly.
GST registration is generally required when turnover reaches the threshold (commonly $75,000; $150,000 for most NFPs). If you are registered, you must lodge even if no GST is payable.
Late lodgements can attract Failure to Lodge penalties and General Interest Charge. Fast, accurate lodgement and a clear ATO plan usually produces the best outcome.
BAS can be lodged through Online services for business or by a registered BAS agent who can also help request remission and set up payment plans.

If your file needs deeper cleanup before lodgement, see BAS Corrections or Bookkeeping Services. If you have no process in place yet, start with BAS Setup and then move into BAS Lodgement for ongoing deadlines.

What to compare before you commit

Scope

Confirm the scope covers the full bas catch up services task: reconciliations, GST/PAYG checks, preparation, lodgement, ATO plan and prevention steps.

Software fit

Ensure the provider is confident in your tools (Xero, MYOB, QuickBooks Online) and will document the workflow, not just name software.

Turnaround & access

Ask when work will start, what access is required, and how urgent issues are escalated around quarter‑end or year‑end.

Qualifications

Prefer a registered BAS agent for ATO lodgements and communications. Check experience with cases like yours (number of periods, payroll complexity).

Commercial fit

Compare fixed‑fee vs hourly, number of periods included, revision policy, and whether you need compliance only or ongoing bookkeeping support.

Communication

Look for clear workpapers, variance explanations and a single point of contact. You should know exactly what is needed from you and when.
