No Tax Treaty? What Australians Need to Know

The Critical Fact: No Australia-Spain Tax Treaty

Australia has tax treaties with many countries, but NOT with Spain. This means there is no bilateral agreement to prevent double taxation. If you're taxed by both Australia and Spain on the same income, you may have to pay tax twice.

This doesn't mean you can't move to Spain, but it means you must plan carefully. Ignorance costs thousands in unnecessary taxes.

Australian Tax Residency: Are You In or Out?

The first step is determining your Australian tax residency status. If you're non-resident for Australian tax purposes, you owe less Australian tax (potentially only on Australian-source income). If you remain resident, you owe tax on worldwide income.

The 183-Day Rule (Simplified)

If you spend more than 183 days in Australia in any income year, you're presumed Australian tax resident. But the rule is more complex:

• Days physically present in Australia matter
• Intent matters (do you intend to stay? family? home?)
• Domicile matters (where's your family base?)

If you're moving permanently to Spain and selling your Australian home, you're likely non-resident for Australian tax. But notify the ATO formally.

Australian Tax: Non-Resident vs Resident

If You're Non-Resident for Australian Tax

You only pay Australian tax on Australian-source income:

• Australian rental property income
• Australian business income
• Australian investment income (dividends, interest)

You don't pay Australian tax on: Foreign pensions, foreign investment income, or Spanish income.

However, you still file a tax return in Australia (if you have Australian-source income) and must notify the ATO of your non-residency.

If You Remain Australian Tax Resident

You pay Australian tax on worldwide income, including Spanish income. This is bad combined with Spanish tax, as you face double taxation without a treaty to help.

Spanish Tax Residency

Once you spend more than 183 days in Spain (or have other indicators like home ownership), you become Spanish tax resident. Spain taxes your worldwide income.

Income taxable in Spain: Spanish pension, Spanish rental income, worldwide investment income, Australian pensions, foreign rental income, wages, business income—basically everything.

Spanish tax rates (2026): Progressive from 19% to 47% depending on income. Average effective rate 25-35% for retirees.

The Double Taxation Problem

Without a tax treaty, here's what can happen:

Example:

• Your Australian superannuation withdrawal: AUD $50,000
• Australian tax on withdrawal: ~AUD $10,000 (at non-resident rate of 20%)
• Spanish tax on the same income: ~EUR €7,500 (at 30% Spanish rate)
• Total tax (both countries): ~EUR €13,000 on AUD $50,000 (~39% effective rate)

Without a treaty, Spain doesn't recognize taxes you paid in Australia as a credit. You pay full Spanish tax even though you already paid Australian tax.

Superannuation and Moving Abroad

This is where Australian retirees face the biggest tax complications.

Accessing Your Super Overseas

You can access superannuation if you're non-resident and meet preservation age (usually 55+). But withdrawals are taxable:

• Non-resident tax: 20% withholding on super payouts (if non-resident)
• Plus Australian tax: You may owe more when you file your tax return
• Plus Spanish tax: Spain also taxes the withdrawal as income

Important: Once you access your super (move it to a "non-resident fund"), you can't put it back. Plan this carefully.

Leaving Super Untouched

You can leave superannuation in Australia and let it grow. You don't owe Australian tax on growth while it stays in the fund. You only pay tax when you withdraw. However, Spain may tax growth if it tracks the fund (consult a tax advisor on this).

Age Pension and Moving Abroad

If you're eligible for the Australian Age Pension, you may still receive it overseas—but reduced.

Centrelink Rules

• Qualifying residence: You must have lived in Australia for 10+ years
• Overseas rate: Usually 0.85x the Australian rate (reduced by 15%)
• Absences: Extended absences may affect payments

Action: Notify Centrelink before leaving Australia. Discuss how absence affects your payments.

Strategies to Minimize Double Taxation (Without a Treaty)

Strategy 1: Become Non-Resident for Australian Tax

If you're moving permanently to Spain, establish non-residency for Australian tax. This limits Australian tax to only Australian-source income. You'll still pay Spanish tax on worldwide income, but at least you're not paying Australian tax on foreign income too.

Strategy 2: Structure Withdrawals Carefully

If accessing superannuation, time withdrawals to spread income across years and tax jurisdictions. Taking it all in one year maximizes tax. Consult both an Australian and Spanish tax advisor on timing.

Strategy 3: Keep Australian Assets Separate

If you have Australian rental property, consider its taxation implications in Spain. Spanish authorities may tax it differently than Australia. This is complex—get professional advice.

Strategy 4: Foreign Tax Offsets (Limited Help)

Australia may allow a foreign tax offset if you pay tax overseas, but this only prevents full double taxation. The offset is typically capped and doesn't fully cover double tax without a treaty.

Getting Professional Help

This is not DIY territory. You need:

• Australian tax accountant: Expert in non-resident taxation and ATO compliance
• Spanish gestor: Tax advisor familiar with foreign residents
• Ideally: Both working together to coordinate your tax strategy

Cost: Expect AUD $2,000–4,000 in professional fees upfront, but this usually saves that amount in taxes.
