Your Tax Return, Done Properly, Without the Office Visit

You do not need to sit in an accountant's office to get your tax return right. A phone call, a video call or a secure upload is all it takes. Our registered tax agents review your income, find every deduction you are entitled to and lodge directly with the ATO for you.

TThe process is the same whether you live in Adelaide, regional South Australia or interstate. You book a time, share your documents, and we handle the rest. Most individual returns are finished in one session.

What separates an online tax agent from doing it yourself on myTax is the review. myTax accepts whatever you type in. We check that your income is complete, your deductions are backed by records, and nothing has been missed or claimed wrongly before we lodge.

Frequently Asked Questions

You can lodge online in 2 ways: yourself through the ATO's myTax, or through a registered tax agent. With The Kalculators you book a phone or video appointment, upload your documents securely, and our tax agent prepares, checks and lodges the return for you. No office visit is needed.
Online individual tax returns at The Kalculators start from $79. Sole trader returns start from $120. Rental properties, capital gains, and business income are included in the fee, and we confirm the price before we start. The fee is tax-deductible in the following year's return.
An online tax agent is better when your return has more than a salary. myTax is free and suits simple returns, but it accepts whatever you enter. A registered tax agent checks your income against ATO data, finds deductions you may have missed and gives you more time to lodge.
The deadline is 31 October 2026 if you lodge yourself. If you join a registered tax agent's client list before 31 October, you can usually lodge later under the agent lodgement program, in many cases up to 15 May 2027.
The ATO issues most refunds for electronically lodged returns within 2 weeks. Returns that the ATO selects for review can take longer.
You need your income statement, bank interest details, private health insurance statement, receipts for work-related expenses and any investment income records. Most income details are pre-filled from the ATO by late July, so we collect the rest from you.
