EBITDA add-backs are adjustments made to a business’s reported earnings to show the true, underlying profit available to a new owner. When you sell an Australian business, buyers normalise your EBITDA by adding back personal expenses, one-off costs, and non-cash items — things that won’t continue after the sale. Done correctly, add-backs increase your stated profit, and because sale prices are set as a multiple of that profit, every legitimate add-back has a multiplied effect on what you walk away with.
That’s the opportunity. The risk is just as real: poorly documented or aggressive add-backs invite pushback from buyers, create problems in financial due diligence, and can collapse deals entirely.
What Are EBITDA Add-Backs?
EBITDA stands for Earnings Before Interest, Tax, Depreciation and Amortisation. It’s the standard profit metric used to value most Australian small and medium businesses — from trade businesses in Perth to professional services firms in Sydney and Melbourne. The “add-backs” are line-by-line adjustments to your financial accounts: expenses stripped out because they’re personal to you, non-recurring, or costs that a buyer simply won’t face.
The result is called normalised EBITDA — a number that reflects what the business can genuinely earn under a new owner who runs it properly.
The rule of thumb that matters most: for an Australian SME selling at a 4x EBITDA multiple, every $100,000 in legitimate add-backs translates to $400,000 on your headline sale price. At 5x, that same $100,000 becomes $500,000. Getting this number right is one of the highest-return things you can do before going to market.
The Most Common Add-Backs
Owner-Related Expenses
This is where most of the value sits for owner-operated businesses, and it’s also where most of the disputes arise. Common items:
Owner salary above market rate. If you pay yourself $320,000 as an owner-director but a competent replacement manager for your role would cost $180,000, the $140,000 difference is an add-back. The buyer is purchasing a business, not your lifestyle. The reverse — where you’re paying yourself below market — creates a negative adjustment we’ll get to.
Personal vehicle costs. Car lease, fuel, insurance, and registration run through the company for a vehicle that serves personal purposes. This is extremely common and almost universally accepted by buyers, provided it’s documented.
Personal insurance and phone. Life insurance, income protection, and mobile phone plans paid by the company for your personal benefit. Small individually but they add up.
Family member salaries. Wages paid to a spouse or adult child where the role is inflated relative to actual contribution, or where the position simply won’t need to be filled by a new owner. This one gets scrutinised — be honest about what value is genuinely being delivered.
Superannuation above the mandated rate. Employer super at the legislated 12% (as at 2026) is a normal business cost. Contributions above that rate are often discretionary and can be added back.
Non-Recurring Costs
One-off expenses that hit the P&L during the review period but won’t repeat:
- Legal costs from a dispute that’s now settled (keep the file; buyers will ask to see it)
- Redundancy payments from a restructure you’ve completed
- One-off equipment write-offs or impairments
- Costs of the sale process itself — advisory fees, legal fees, and the cost of preparing your Information Memorandum
- Significant renovation or fitout costs that were expensed rather than capitalised
COVID-Related and Government Payments
Many Australian business P&Ls still carry distortions from the pandemic years. JobKeeper payments that boosted profit in 2020–21 are negative add-backs — they inflate profit in a way that won’t recur. One-off cash flow boost payments are treated similarly. If your review period covers any year heavily affected by government support programs, expect a buyer’s accountant to isolate and normalise those years separately. Don’t try to hide it; it’s on your tax returns.
Non-Cash Items
Depreciation and amortisation are stripped out of EBITDA by definition (the D and A). But if you’re presenting an EBIT number rather than true EBITDA — which some accountants do by default — you’ll need to add these back explicitly. Amortisation of goodwill from a prior acquisition is also commonly normalised.
What Shouldn’t Be Added Back
This is the section most sellers skip and most buyers use against them (which, when you think about it, is entirely predictable).
Not everything that hurts your profit figure is a legitimate add-back. The test is simple: if you’d need to spend that money again next year to keep the business running at its current level, it’s not an add-back.
Recurring “discretionary” spending. Marketing, digital advertising, training, and software subscriptions — if these have run consistently for three or four years, they’re not discretionary. They’re the engine. Calling them add-backs is a negotiating tactic, not an accounting adjustment, and buyers know exactly what it looks like.
Staff costs you eliminated before the sale. If you cut two people in the 12 months before going to market to improve the numbers, a buyer will add those costs back in the opposite direction. Net result: your normalised EBITDA ends up where it started, and you’ve created a staffing gap that raises questions about operational sustainability.
Rent reflecting a below-market lease you control. If the property is owned by a related entity and you’ve been paying rent at half the market rate, buyers will normalise this — which means adding the rent shortfall as a cost, not removing it. This is especially common in WA manufacturing and trade businesses where the owner holds the land separately.
Owner salary where the owner genuinely does essential work. If you’re the lead engineer, the main client relationship holder, or the key technical operator and you’ve been paying yourself $120,000 to keep cash in the business, you can’t add back that entire salary. A buyer will apply a market-rate cost for your replacement, and the add-back is the difference — which, in this scenario, might actually be a negative number.
I saw a business sale a couple of years back where the owner had added back $90,000 labelled as “discretionary marketing spend.” The problem was that this spend had run every year for four years and had been directly responsible for a significant portion of inbound leads. The buyer’s accountant identified it in the first week of financial due diligence. The add-back was removed, the normalised EBITDA dropped by $90,000, and at a 4x multiple the deal repriced by $360,000. The owner also spent an extra eight weeks in negotiations he could have avoided. It’s a painful lesson but a common one.
Negative Add-Backs: The Adjustments That Go the Other Way
This is the conversation sellers don’t want to have, but it’s unavoidable in any credible normalisation process.
Negative add-backs reduce your EBITDA. They apply when your reported profit is higher than a new owner could realistically expect to earn.
Owner underpaying themselves. This is the big one. If you’ve been drawing $80,000 as a working owner-director of a business that genuinely requires a $200,000 manager to replace you, a buyer deducts $120,000 from your EBITDA. This is sometimes called PEBITDA — Proprietors’ EBITDA — and it reflects the earnings of the business as if it were managed at arm’s length. For businesses where the owner is deeply embedded in operations, this adjustment can be substantial.
Above-market related-party transactions. If you sell product or services to a related entity at inflated prices, or buy inputs from a related entity at below-market rates, buyers will normalise these to market rates. The adjustment goes against you.
One-off income. Government grants, insurance proceeds, a settlement payment, or a one-time contract that won’t recur. If it’s not repeatable, it doesn’t count towards maintainable earnings — and any buyer worth dealing with will model it out.
Deferred maintenance. Not an accounting line item, but buyers in manufacturing, transport, and hospitality often apply an adjustment (or a price reduction) for equipment that should have been replaced and wasn’t. In WA mining services businesses, this can run into the hundreds of thousands.
A rough sense-check: total your positive add-backs, then total your negative adjustments. The net figure as a percentage of raw EBITDA tells you something. If you’re normalising more than 30–40% of your reported profit in either direction, expect pushback and extended due diligence. If your numbers are relatively clean, you’ll move faster and on better terms.
How Add-Backs Differ by Industry
Add-back conventions vary across sectors, and buyers in each sector have seen enough deals to know what’s normal.
Trade businesses (plumbing, electrical, construction): Owner labour is often undercosted — the working owner bills their time at tradesperson rates but runs the business too. Expect to model both the technical labour replacement cost and the management replacement cost separately.
Professional services (accounting, legal, consulting): Client portability is the main issue — buyers will discount EBITDA for revenue that’s personally attached to the departing owner. Add-backs on owner salary are closely tied to whether the owner is staying post-sale.
Hospitality (restaurants, cafes, accommodation): Owner meals, travel, and personal entertaining run through the accounts at rates that require careful documentation. One-off renovation costs are common, as are government grants from various tourism recovery programs.
Healthcare and allied health: Medicare and private health insurance billing arrangements sometimes create one-off payment adjustments. Equipment write-offs and practice management system upgrades are common non-recurring items.
How to Present Add-Backs Without Creating Problems
The format of your add-back schedule matters as much as the content. A credible schedule:
- Lists each item separately, with a plain-language description of what it is and why it’s adjustable
- Shows which financial year the cost appears in and which account line it comes from
- Is supported by documentation — payroll records, bank statements, ATO activity statements, board minutes
- Is consistent across the review period (typically three years)
- Is conservative — when in doubt, leave it out
Your add-back schedule will be handed to the buyer’s accountant during financial due diligence. It needs to take five minutes to verify, not five weeks to unpick. The goal is to present numbers that are harder to argue with than to accept.
There’s also a legal dimension worth keeping in mind: your representations about normalised EBITDA generally end up as warranties in the sale agreement. Misrepresenting them — even by accident — can create post-settlement liability. This isn’t abstract. Australian business sale litigation frequently involves disputes over how add-backs were calculated and disclosed. For a deeper look at how the sale structure affects your obligations, see our guide to the tax implications of your sale.
If you’re working with a corporate advisor, they’ll prepare the normalised EBITDA bridge as part of your Information Memorandum. If you’re going to market without professional support, at minimum have your accountant sign off on the schedule before it goes to buyers. Part of preparing your financials for sale is making sure this document is tight before anyone else sees it.
The Bottom Line
Normalised EBITDA is the number everything else in your sale negotiation flows from. Get it right — legitimate, documented, defensible — and you start from a strong position. Pad it and you create a due diligence problem that will find you regardless.
The sellers who get the best outcomes are the ones who did the normalisation work honestly, presented it cleanly, and let the numbers speak for themselves. That sounds straightforward. In practice, it requires knowing which items are genuinely addable, which aren’t, and how to document the ones that are.
