EBITDA Adjustments and Normalisation: A Practical Guide for Business Valuation

Introduction

When a business valuer says they're applying a "4x EBITDA multiple," they never mean raw EBITDA straight from your profit and loss statement. Raw EBITDA includes one-off items, non-recurring expenses, excess owner benefits, and sometimes personal costs that have nothing to do with the business's sustainable earning capacity.

The valuation is based on adjusted or normalised EBITDA-the earnings a willing buyer could reasonably expect the business to generate going forward.

This distinction matters enormously. A $2M EBITDA business with $400K of legitimate add-backs is actually worth $2.4M x multiple-not $2M. At a 4x multiple, that's a $1.6M difference. For Australian SME owners preparing for a sale, understanding what can and cannot be adjusted is the single highest-value thing you can do before engaging a valuer.

This guide walks through every major category of EBITDA adjustment with real Australian examples, so you know what to claim and how to support it.

What Adjusted EBITDA Actually Means

Adjusted EBITDA starts with your statutory EBITDA and adds back or removes items that are:

• Non-recurring - happened once, unlikely to repeat
• Non-operating - not part of the core business
• Discretionary - owner-specific expenses a new owner wouldn't incur
• Above market - costs that exceed what an arm's-length buyer would pay

The goal is to arrive at a normalised, sustainable earnings figure that represents what a new owner can expect to earn, operating the business as a going concern.

Category 1: Non-Recurring Items

These are one-off expenses that distort a single year's EBITDA. The valuer will add them back if they can be satisfied they won't recur.

Common examples

• Legal fees for a one-off dispute - A lawsuit over a supplier contract cost your business $85K this year. That's not an ongoing cost.
• Redundancy payouts - You restructured management and paid $120K in redundancy. The new structure is permanent.
• Relocation costs - Moving to a new premises cost $60K. You're settled for the next five years.
• IT system migration - A $95K ERP implementation is done. No further capitalised software costs expected.
• Natural disaster / COVID-related costs - Hail damage to the warehouse roof, flood repairs, or pandemic-specific health measures.

What the valuer needs: Invoices, contracts, or correspondence proving the event is genuinely one-off and not recurring annually in some form.

What won't be accepted

• "Regular one-off" items - If you claim a "one-off" legal cost every year, that's just a recurring legal cost. Valuers look at a three-year trend for exactly this reason.
• Routine maintenance - Even large maintenance items are expected in most businesses. A $40K boiler replacement isn't an adjustment; it's normal capex that EBITDA already ignores.

Category 2: Excess Owner Benefits

This is the biggest adjustment category for Australian SMEs. Owner-operated businesses frequently include personal or above-market expenses that a professional manager wouldn't incur.

Salary above market rate

Many SME owners pay themselves more (or less) than a replacement manager would cost. The adjustment is the difference between actual remuneration and market-rate remuneration for the role.

Example: You pay yourself $350K/year as managing director. A market-rate MD in your industry and city would cost $220K including super. The $130K difference is an add-back.

What if you pay yourself below market? The valuer will adjust DOWN, reducing EBITDA. Underpaying yourself doesn't inflate business value-it signals the business can't support market-rate management.

Personal expenses through the business

Common add-backs include:

• Personal vehicle expenses (the family car registered under the ABN)
• Family travel combined with business trips
• Personal mobile phones, school fees, health insurance
• Home office costs exceeding genuine business use
• Entertainment and meals beyond legitimate client entertainment

ATO relationship: If the ATO would disallow the deduction in a review, it's probably a personal expense. But FBT-exempt items (certain car parking, some entertainment) may still be legitimate adjustments if they're genuine business costs.

Related-party transactions

If you lease the business premises from a related entity (your own super fund, a family trust), the rent should be at market rates. Above-market rent to a related party is an add-back. Below-market rent is a deduction from EBITDA.

Example: Your SMSF owns the office and charges $180K/year in rent. Comparable commercial space in the same suburb goes for $120K. The $60K difference is an add-back.

Category 3: Non-Operating Income and Expenses

Not everything that hits your P&L belongs in an EBITDA calculation.

Add back: Non-operating expenses

• Interest expense - Already added back in the move from Net Profit to EBITDA. No double-counting.
• Foreign exchange losses on non-trade items - A $30K FX loss on a one-off equipment purchase from Germany. This is a financing decision, not an operating cost.
• Goodwill impairment - A paper write-down that doesn't affect cash flows.

Remove: Non-operating income

• Government grants - JobKeeper, R&D tax incentives, or COVID grants inflated EBITDA in the years they were received. These should be stripped out for normalisation unless the new owner has reasonable certainty of continuing to receive them.
• One-off asset sales - Selling a piece of machinery at a profit isn't operating income.
• Investment income - Dividends from unrelated shareholdings aren't part of your core business EBITDA.

Category 4: Above-Market or Below-Market Costs

Rent (non-related party)

If you lease from an unrelated landlord at above-market rates (unusual but possible), that's an adjustment. More commonly, below-market rent from a long-standing lease should be adjusted UP to market, reducing EBITDA.

Management fees

Many SMEs pay management fees to a related family company or trust structure. The valuer needs to understand what these cover. If they represent genuine services at market rates, they stay. If they're a profit extraction mechanism, they're scrutinised.

Director's fees to non-executive family members

A $40K director's fee to a spouse who attends no board meetings and provides no services is a clear add-back. The valuer will ask: would a new owner incur this cost? If not, it's adjusted.

Putting It Together: A Worked Example

Consider a Melbourne-based IT services business being prepared for sale:

The valuation implications:

• Raw EBITDA basis (4.5x multiple): $5.4M
• Adjusted EBITDA basis (4.5x multiple): $6.65M
• Difference: $1.25M - entirely from legitimate adjustments that any professional valuer would accept with proper documentation.

The Three-Year Rule

Valuers rarely rely on a single year's adjusted EBITDA. The standard approach is a three-year weighted average:

The current year gets the heaviest weighting because it's most representative of future performance. This smoothed figure becomes the base for multiple valuation.

Documentation Requirements

Every adjustment needs supporting evidence. Without it, valuers and buyers will treat your claimed adjustments as marketing, not fact.

Strong documentation:

• Tax returns and financial statements for three years
• A schedule of adjustments with clear rationale for each
• Invoices or contracts for one-off items
• Market salary benchmarking (Hays, Robert Half, or industry surveys)
• Independent rental valuation for related-party property
• Director's declaration confirming adjustments are accurate

Weak documentation:

• "Trust me" explanations
• Verbal recollections without written support
• Adjustments based on what you "could" have done rather than what you did

Conclusion

EBITDA adjustments are not about inflating your numbers-they're about presenting a true, sustainable earnings picture to a valuer or buyer. A well-documented normalisation can add hundreds of thousands to your valuation. A poorly supported one can destroy credibility and derail a sale.

Work with your accountant to prepare an adjustments schedule before engaging a valuer. The time spent documenting legitimate add-backs is the highest-ROI preparation you can do.

Frequently Asked Questions

What is the difference between EBITDA and adjusted EBITDA?

EBITDA starts from net profit and adds back interest, tax, depreciation, and amortisation. Adjusted EBITDA further adds or subtracts one-off items, non-recurring expenses, excess owner benefits, and non-operating income to arrive at a sustainable earnings figure.

How far back should I adjust EBITDA for a valuation?

Most valuers look at the most recent three financial years plus the latest available management accounts. A three-year weighted average (with the current year weighted most heavily) gives the most defensible normalised EBITDA figure.

Can I add back capital expenditure to EBITDA?

No. EBITDA already excludes capex by ignoring depreciation. If your business requires significant ongoing capex, consider using free cash flow instead of EBITDA for valuation purposes.

How do valuers verify my adjustments?

Every adjustment should be supported by documentation-tax returns, financial statements, supplier invoices, or director declarations. Valuers will request a schedule of adjustments with supporting evidence before signing off.

Do the same EBITDA adjustments apply for CGT purposes?

Generally yes, but the ATO requires adjustments to be supported by a compliant valuation report. For CGT purposes, the crystalising tax event means adjustments must be particularly defensible, as the ATO may review them.
