Costs and tax

Business Relief

Business Relief reduces the taxable value of qualifying trading business property by 90% for Capital Acquisitions Tax purposes. A family-owned trading company worth €800,000 is reduced to €80,000 for CAT purposes, often eliminating the charge entirely. Strict conditions apply: active trading, two-year holding period, qualifying business type.

A son inherits his late father's trading business, valued at €700,000, alongside the family home. Without relief, the business alone triggers CAT at 33% of €300,000 above the Group A threshold (assuming the home value is absorbed by Dwelling House Exemption), which is €99,000. With Business Relief, the business value is reduced to €70,000 for CAT, well within the threshold. CAT on the business falls to zero.

Business Relief is the lesser-known sibling of Agricultural Relief. It does similar work for trading businesses: eliminates most of the CAT charge where the family business is being inherited.

What qualifies as business property

Business Relief applies to:

  • Unquoted shares in a trading company: shares in a company that is not listed on any stock exchange
  • A sole-trader business: the trading assets of a business carried on by the deceased as a sole trader
  • Partnership interest: the deceased's interest in a partnership carrying on a trade
  • Land, buildings, machinery, and equipment used for the purposes of the business, where they are owned by the deceased and used by a company the deceased controlled

Not everything associated with a business qualifies:

  • Shares in a quoted (listed) company do not qualify, no matter how much of the company the deceased held
  • Investment businesses (holding property for rental, dealing in shares, holding portfolios) do not qualify; only active trading businesses
  • Assets held personally but not used in the business (cash surpluses beyond working capital, personal investments held by the business)
  • Property held primarily for rental to unconnected parties is usually excluded

The two-year ownership test

The deceased must have owned the business property for at least two years immediately before death. Shorter periods disqualify the relief.

Exceptions apply where the deceased inherited the business from a spouse who had themselves held it for two years, allowing continuity within a family. Similar exceptions apply where one qualifying business is replaced with another qualifying business (for example, the deceased sold business A and immediately bought business B).

The trading test

The business must be carrying on a trade at the date of death. "Trade" in Irish tax law has a specific meaning: active commercial activity with the intention of earning a profit, involving regular transactions. The Revenue tests include frequency of transactions, volume, organised structure, and whether the activity is recognised as a trade.

Common edge cases: - A property rental business: usually does not qualify, even where rents are substantial, because Revenue treats passive receipt of rent as investment rather than trading. - A hotel or guesthouse: usually qualifies, because hospitality is an active trade. - A farm: qualifies for Agricultural Relief instead; the two reliefs are mutually exclusive but Agricultural Relief is usually more favourable. - A professional practice (solicitor, accountant, medical): qualifies, subject to conditions on how the practice is structured. - A property development company: usually qualifies as trading if it is actively developing for sale. - A property holding company (owns and lets property long-term): usually does not qualify.

The boundary is blurred and Revenue queries are common for borderline cases.

The six-year retention

If Business Relief is claimed, the beneficiary must retain the business property in qualifying use for six years from the valuation date. Specifically:

  • Shares cannot be sold or redeemed within six years (unless in specific permitted circumstances like a share-for-share exchange)
  • Sole-trader business assets cannot be sold out of the trade within six years
  • The business must continue to trade throughout the retention period
  • Conversion from trading to investment activity within six years triggers clawback

Proportionate clawback applies to partial disposals. Selling 30% of the shares within six years of inheriting produces a clawback of 30% of the relief.

Difference between Business Relief and Agricultural Relief

Feature Agricultural Relief Business Relief
Applies to Agricultural property and livestock Trading businesses, unquoted shares
Reduction 90% 90%
Pre-death holding period None (but land-use conditions) 2 years
Beneficiary test Active farmer test (or lease to one) No beneficiary qualification test
Six-year retention Yes Yes
Exclusion Development land Investment businesses, quoted shares

Where an estate includes both a farm and a trading business, the two reliefs can both apply simultaneously to different parts of the estate.

Worked example: relief applies

A son inherits his late mother's wholesale distribution company. The shares, valued at €900,000, are held entirely by his mother, who founded and actively ran the business for 20 years. The son plans to continue running the business.

  • Business property value: €900,000
  • Business Relief: 90% reduction
  • Business value for CAT: €90,000
  • Group A threshold: €400,000
  • Taxable amount: €0 (well under threshold)
  • CAT: €0

Without the relief, CAT would be 33% of (€900,000 - €400,000) = €165,000.

The son must retain the shares and keep the business trading for six years to avoid clawback. At year seven, he can sell without CAT consequence.

Worked example: relief fails

A niece inherits her aunt's rental property portfolio held through a company. The company owns 4 residential properties worth €1.2 million in total. The company collects rent but carries out no development, management, or services beyond what a passive landlord would.

  • The trading test: failed. Passive property rental is investment activity, not trading.
  • Business Relief: does not apply
  • Group B threshold: €40,000
  • Taxable amount: €1,160,000
  • CAT at 33%: €382,800

The niece's options are to pay the CAT (possibly by selling one or more properties), borrow against the portfolio, or restructure the business toward an active trade (property development) before any future inheritance. Restructuring after the fact does not help.

When professional advice is essential

Business Relief is a specialist relief. Retain a tax adviser for any estate involving:

  • Unquoted shares worth above €200,000
  • Any sole-trader business being inherited
  • A family company with mixed trading and investment activity
  • Any question whether a specific business is "trading" within the Revenue meaning
  • Cross-border business structures (UK companies, IP held abroad)
  • Any possibility of a sale or restructuring within the six-year retention window

For a clearly-trading family business with straightforward shareholding structure, the Complete Bundle workbook handles a standard Business Relief computation. For anything that looks even slightly borderline, professional advice is strongly recommended.
