That matters if you're a U.S. citizen, Green Card holder, or other U.S. taxpayer in Australia receiving dividends, interest, rent, or royalties. In tax year 2021, IRS data shows 5,016,807 returns included a Form 1116. Plenty of those filers hit a ceiling they didn't see coming.
This guide covers how the passive limit works, how to calculate excess foreign tax, how carryovers are tracked, how FEIE interacts, and what records to keep.
Key Takeaways
- The passive limit is the smaller of qualifying foreign tax and U.S. tax on passive foreign-source income.
- Passive and general-category income are calculated separately.
- Excess tax carries back one year and forward ten, tracked by category and origin year.
- Australian tax, withholding and franking credits are not automatically creditable.
What Does Passive Income Excess Limit Mean on Form 1116?
"Excess limit" usually describes foreign taxes that exceed the credit limitation. It isn't passive income crossing a threshold. Two terms get confused:
- Excess limitation: unused credit capacity (limitation minus qualified taxes).
- Excess foreign taxes: taxes above the limitation, potentially carried to other years.
Passive-Category Income
Passive income generally includes:
- Dividends, interest, royalties, rents and annuities
- Specified investment gains
Active-business rents and royalties are exceptions. High-taxed income is reclassified out of the passive basket. Check unusual items (pensions, trusts, controlled foreign corporation distributions) before assigning a category.
Each category needs its own Form 1116. A passive credit generally can't offset U.S. tax on general-category wages or active business income.
Which Foreign Taxes Qualify
Creditable tax is generally imposed on you, legally owed by you, paid or accrued, and must be an income tax or a tax in lieu of one. These typically don't qualify:
- Amounts reasonably certain to be refunded or recoverable under a treaty
- Noncompulsory withholding
- Penalties and interest
- VAT and property taxes
Australian franking credits deserve care. Tax paid by a company on dividends isn't automatically the individual shareholder's creditable tax.
Hypothetical Example
Assume (illustration only) you owe USD $1,200 of creditable passive foreign tax and your passive limitation is USD $800. You claim $800 this year. The remaining $400 becomes excess foreign tax, eligible for carryover if documented.
How Is the Passive Income Limitation Calculated?
The IRS Publication 514 formula: U.S. income tax multiplied by foreign-source taxable income in the category, divided by worldwide taxable income. The actual form adds required adjustments.
Inputs You Need
- Net passive foreign-source income (after related deductions, not gross receipts)
- Worldwide taxable income
- U.S. tax before the credit
- Creditable foreign taxes, converted to USD
- Treaty and sourcing adjustments
Expenses and losses reduce passive taxable income, which shrinks the U.S. tax allocated to the category.
The Form 1116 Workflow
Line numbers change, so work by each step’s purpose:
- Report foreign-source passive income and deductions.
- Report qualifying foreign taxes.
- Compute the category limitation.
- Determine the allowable credit.
- Reconcile excess and carryovers.
Worked Hypothetical
Illustrative figures, not a real client result:
| Item | Amount |
|---|---|
| Worldwide taxable income | $100,000 |
| Net passive foreign-source income | $20,000 |
| U.S. tax before credit | $18,000 |
| Foreign-income ratio | 20% |
| Limitation ($18,000 × 20%) | $3,600 |
| Creditable foreign tax | $4,500 |
| Current-year credit | $3,600 |
| Excess foreign tax | $900 |
Why Your Credit May Be Lower Than the Australian Bill
- Currency conversion: paid-method taxes use the payment-date rate. The IRS's 2025 average was AUD 1.551 per USD.
- Preferential-rate adjustments: qualified dividends and capital gains may need downward adjustment (2025 factors of 0.4054 and 0.5405).
- Treaty caps: the U.S.-Australia treaty generally caps source-country withholding at 15% on individual dividends, 10% on interest and 5% on royalties, for treaty residents.
- Excluded income: tax tied to FEIE-excluded income isn't creditable.
- Expenses and U.S.-source income: both change the ratio.
How Do Carryovers Work for Excess Passive Foreign Taxes?
Under IRC 904(c), eligible excess taxes can generally be carried back one year, then forward ten, in that order, to the extent you can use them. An unusable intervening year doesn't extend the period.
Category and Capacity Rules
Carryovers are computed by category:
- Passive excess can't move to the general category just because that category has spare limitation
- Excess must meet the passive limitation in the receiving year
- Prior-year carryovers aren't applied when the current year already has its own excess taxes
Tracking With Schedule B
Schedule B tracks each carryover's origin year, beginning balance, amounts used, carryback, expiration, current excess and remaining balance. Line 3, column (xiv) feeds Part III, line 10 of Form 1116. Use the form and instructions for your filing year.
Ordering Principle
- Review current-year taxes and available limitation.
- Apply older unexpired carryovers first.
- Test the prior-year carryback.
- Preserve the remainder.
Records Checklist
- Prior Forms 1116 and Schedule B
- Australian assessments and withholding records
- Dividend and interest statements
- Refund claims and treaty documents
- Exchange-rate workings
Unused credits expire, so identify older passive balances first.
How FEIE and Other Rules Affect the Passive FTC
The Foreign Earned Income Exclusion covers qualifying earned income, up to $132,900 for 2026 ($130,000 for 2025). Passive interest and dividends aren't earned income and stay taxable.
FEIE still affects the credit. Section 911(d)(6) disallows credit for tax allocable to excluded income, and the same income can't get both benefits.
Crediting tax on income covered by the exclusion may revoke the election. Only income included on your U.S. return counts as taxable income in the FTC computation.
Other Rules That Shift the Result
- Qualified-dividend and capital-gain adjustments
- High-tax kickout from the passive basket
- Treaty resourcing, including Article 22(4) for U.S. citizens resident in Australia
- Foreign-tax refunds, which may require redetermination reporting
- Simplified election for $300 ($600 joint) of passive-only income and taxes on payee statements (confirm current thresholds)
- No carry of unused taxes to or from a year under the simplified election
Check Your Taxpayer Type
Individuals generally use Form 1116. Corporations and certain entities may use Form 1118. Confirm the form before applying individual rules to an Australian business.
Common Mistakes and When to Seek Professional Help
These Form 1116 mistakes show up often on returns that claim Australian foreign tax credits:
- Treating all Australian tax as creditable
- Mixing passive and general baskets
- Using gross receipts instead of net taxable income
- Claiming tax on FEIE-excluded income
- Skipping currency conversion or carryover schedules
- Missing substantiation for Form 1116 claims
TIGTA found $94.9 million claimed on 2010-2012 returns lacking required documentation.
Pre-Filing Checklist
- Confirm the income category.
- Confirm the tax is legally owed and nonrefundable.
- Reconcile Australian statements to USD.
- Calculate the limitation.

Frequently Asked Questions
What is the passive income excess limit on Form 1116?
There's generally no fixed dollar limit. The credit is capped by U.S. tax attributable to passive foreign-source taxable income, calculated under the current Form 1116 instructions.
How does foreign tax credit carryover work on Form 1116?
Eligible excess taxes can generally go back one year and forward ten. Category limits, ordering rules, expiration and Schedule B tracking all apply.
What is the Foreign Earned Income Exclusion (FEIE)?
FEIE excludes qualifying foreign earned income from U.S. tax. Foreign taxes on the excluded income generally can't also be claimed as a credit.
Can passive-category foreign tax credits offset general-category income?
No. Categories are calculated separately, so passive excess generally can't offset U.S. tax on general-category wages or active business income.
Do I need a separate Form 1116 for passive income?
Generally yes, one per category, unless the simplified election applies. Confirm the requirements for your filing year.
What happens if my passive foreign taxes exceed the Form 1116 limit?
You claim only the allowable passive amount now. Eligible excess may be carried back or forward if documented and tracked.
