Quarterly BAS, Lodged on Time, Every Quarter, No Panic

We lodge your quarterly BAS on time so it stops sliding to the bottom of your list. As your registered BAS agent we handle the GST, PAYG withholding, PAYG instalments, fuel tax credits and the WET, lodged with the ATO from $75 per quarter, and lodging through us gives you an extra four weeks on every deadline.

How the Quarter Feels Now, and How It Feels With Us

Most owners do not lodge late because they are careless. The due date lands in the middle of running the business, and the activity statement keeps sliding to the bottom of the list. Here is what changes once it is our job, not yours.

The usual BAS scramble
  • The due date creeps up while you are quoting jobs, paying staff and chasing your own invoices.
  • You open the software the week it is due and the bank feed has not been reconciled since the last one.
  • You are guessing on fuel tax credits and which expenses actually carry GST, then hoping it is close enough.
  • A failure-to-lodge letter turns up, and you are wearing the penalty for being a few days behind.
  • You are a few quarters back and putting off the catch-up because you do not know how big the bill is.
With KSH TAX
  • We track every cycle the ATO has you on, quarterly, monthly or annual, and start three weeks out so nothing creeps up.
  • Your Xero or MYOB is reconciled against the bank before a single label is filled in.
  • A registered agent checks the GST treatment, fuel tax credits and PAYG labels, so the figures are right, not rounded.
  • Lodging through an agent gives you an extra four weeks, and safe-harbour cover means an agent error is not your penalty.
  • Behind by three, five or eight quarters? We work the oldest first and negotiate the ATO position as we go.

Every BAS Label, Every Quarter

Prepared from your Xero or MYOB books, reconciled against bank, reviewed by a registered BAS agent, lodged with the ATO.

  • GST collected and paid (G1, G2, G3, G10, G11)
  • PAYG withholding from wages (W1, W2)
  • PAYG instalments (T1, T2, T7)
  • Fuel tax credits for eligible vehicles and machinery
  • WET (wine equalisation tax) and LCT if applicable
  • Bank reconciliation before lodgement
  • ATO portal lodgement with payment reference number
  • Payment plan negotiation with the ATO if cashflow tight

We Stand Between You and the ATO Every Quarter

Your Name Comes Off the Deadline

Lodging through us moves the due date back four weeks and puts a registered agent on the file. The quarter stops being something you have to remember.

The Penalty Risk Sits With Us

Under the ATO safe-harbour rules, a lodgement error on our side is not your penalty. We carry the responsibility a self-lodger has to carry alone.

We Argue Your Corner With the ATO

If a penalty has already landed or cashflow is tight, we put the case for remission and set up a payment plan, so you are not negotiating with the ATO on your own.

What Perth Business Owners Ask About BAS

How much does BAS lodgement cost in Perth?

From $220 + GST per quarter if your books are clean and we just prep and lodge. If we are also doing your monthly bookkeeping, BAS is included from $315 + GST/month.

Do I get longer to lodge if I use a registered BAS agent?

Yes. Businesses lodging quarterly BAS via a registered agent get up to 4 extra weeks beyond the standard ATO deadline, every quarter. Free benefit just by using us.

I am several quarters behind. Can you catch me up?

Yes. We handle BAS backlogs every month. Oldest first, then the rest in sequence. We will also negotiate any ATO penalty or payment plan as part of the catch-up.

What is the difference between a BAS agent and a tax agent?

A BAS agent lodges quarterly business activity statements (GST, PAYG). A tax agent lodges annual income tax returns. KSH TAX is both, so you get one firm for both.

Can you pay the BAS for me?

We do not hold client funds. Once the BAS is lodged, we give you the payment reference number and BPAY details and you pay the ATO directly. If cashflow is tight we will negotiate a payment plan.
