OnlyFans Tax Deadlines Australia 2025-26 | Key Dates + Budgeting Guide

• Your individual tax return is due 31 October each year (self-lodge) or up to 15 May the following year through a registered tax agent.
• Quarterly BAS deadlines fall on the 28th of October, February, April, and July.
• Missing a deadline costs $330 per 28-day period overdue, up to $1,650. General Interest Charge runs at roughly 11% per annum, and from 1 July 2025 it’s no longer tax-deductible.
• Set aside 25 to 30% of every payout into a separate tax savings account. Don’t wait until July to figure out what you owe.

Your complete deadline calendar for 2025-26

Here’s every date that matters. Print this, screenshot it, or save it somewhere you’ll actually look at it.

Annual tax return

To qualify for the extended deadline through a tax agent, you need to be registered on their client list **before** 31 October. Don’t call an accountant on 30 October and expect the extension to kick in.

Your return covers the financial year from 1 July 2025 to 30 June 2026. If you owe tax, payment is generally due by the lodgement date.

Quarterly BAS (if GST-registered)

If your total business turnover exceeds $75,000, you must register for GST and lodge a Business Activity Statement each quarter. For more on when GST applies, see our GST guide for custom content.

If the due date falls on a weekend or public holiday, lodgement and payment are due on the next business day.

PAYG instalments

If the ATO issues you a PAYG instalment notice (they’ll do this automatically once your income triggers the threshold), you’ll make quarterly payments toward your expected tax liability.

These amounts are based on your prior year’s income. You can vary the instalment amount if your income has changed significantly, but be careful: if you reduce it too much and end up owing a lot at year-end, the ATO may charge interest on the difference.

Super contributions (if you employ staff)

Most sole trader OnlyFans creators don’t have employees, but if you do (an editor, photographer, or virtual assistant on your payroll), super is due quarterly:

The super guarantee rate is **12%** of ordinary time earnings from 1 July 2025. Miss the deadline by even one day and you’re liable for the Superannuation Guarantee Charge, which adds interest and an administration fee, and the payment is no longer tax-deductible.

As a sole trader, you’re not required to pay super for yourself. But voluntary concessional contributions (up to $30,000 per year) are tax-deductible and can be a smart way to reduce your taxable income while building retirement savings.

Other dates to know

## What happens if you miss a deadline

Failure to lodge penalty

The ATO charges 1 penalty unit per 28-day period your return or BAS is overdue. A penalty unit is currently $330 (from 7 November 2024). The maximum for individuals is 5 units, or $1,650.

That might sound manageable, but it compounds with other consequences.

General Interest Charge

Outstanding tax debts accrue GIC at approximately 11% per annum (the exact rate is set quarterly by the ATO). This ticks from the original due date, not from when the ATO sends you a notice.

Here’s the kicker: from 1 July 2025, GIC is no longer tax-deductible. Previously you could at least offset the interest against your income. Now it’s pure cost. This makes timely payment significantly more important than it used to be.

Amended assessments and shortfall penalties

If the ATO detects unreported income (and with SERR, they will), they can issue an amended assessment. On top of the tax you should have paid, they’ll add:

• 25% of the shortfall for failure to take reasonable care
• 50% for recklessness
• 75% for intentional disregard

These penalties can be reduced if you voluntarily disclose before the ATO contacts you. See our guide on ATO reviews for more detail.

How to budget so tax time doesn’t hurt

The biggest mistake OnlyFans creators make isn’t failing to lodge. It’s spending everything and having nothing left when the bill arrives. Here’s a simple system that actually works.

Step 1: Open a separate tax savings account

Set up a high-interest savings account with no card attached. Call it “Tax” or “ATO” so you never confuse it with spending money. Every single time OnlyFans pays you, transfer a percentage into this account before you spend anything else.

Step 2: Work out your set-aside rate

As a rough guide:

These percentages account for income tax and Medicare levy. If you’re GST-registered, you’ll need to factor that in separately (though you also get to claim GST credits on business expenses, which offsets some of it).

Step 3: Review quarterly

Every quarter (line this up with your BAS or PAYG instalment dates), check your actual earnings against your estimates. If you’ve earned more than expected, top up the tax account. If less, you’ll have a nice buffer.

Step 4: Don’t touch the tax account

This is the hardest part. That money isn’t yours. It belongs to the ATO. The interest it earns in the savings account is a small bonus, but the principal isn’t for spending.

Step 5: Track everything in real time

Your OnlyFans dashboard (Settings > Statements) shows your earnings, but it doesn’t track expenses. Use accounting software like Xero or even a simple spreadsheet to log income as it’s earned and expenses as they’re paid. When tax time comes, your accountant will thank you, and your bill will be lower because you won’t miss deductions.
