Tax rates and loss carry-back tax offset for companies qualifying as base rate entities (BREs) in Australia.
In this article:
- Base Rate Entity Qualification Criteria
- Base Rate Entity Tax Rates by Income Year
- Loss Carry-Back Tax Offset Opportunity
- Additional Key Considerations
Base Rate Entity Qualification Criteria
- Aggregated turnover for the income year is below $50 million.
- 80% or less of assessable income in the income year is base rate entity passive income (such as dividends, royalties, rent, some interest, and certain capital gains).
- These criteria are assessed annually; a company may qualify in some years and not in others depending on its circumstances.
- The turnover threshold and passive income test have remained stable since 2018–19.
Base Rate Entity Tax Rates by Income Year
- 2018–19 to 2019–20: 27.5%
- 2020–21: 26%
- 2021–22 onwards (including 2024–25 and 2025–26): 25%
- Other companies pay the standard 30% rate.
Loss Carry-Back Tax Offset Opportunity
- If a BRE incurs losses in a year, it can carry those losses back to a previous profitable year and receive a refundable tax offset.
- The refundable offset rate is the base rate entity tax rate that applied in the loss year (e.g., 27.5%, 26%, or 25% depending on the year).
- This can often produce a better economic result than carrying losses forward, especially for loss years taxed at the higher BRE rates of 27.5% or 26%.
Additional Key Considerations
- The base rate entity tax rate of 25% continues to apply effectively for the 2024–25 and 2025–26 income years.
- Qualification as a BRE is determined independently for each income year based on that year's turnover and income composition.
- The aggregated turnover threshold for BRE status has remained at $50 million since 2018–19 with no announced changes.
- When calculating tax outcomes or planning with loss carry-backs, the applicable BRE tax rate for the relevant loss year must be used.
- Companies not meeting the BRE criteria pay the standard 30% company tax rate.
