Add backs are the expenses on your P&L that a new owner will not carry: your salary, your personal costs and the one time hits. Added back, they show a buyer what the business really earns. They are often the single biggest lever on your sale price, and they are worth nothing if you cannot prove them.
Here is what counts, what does not, and the paperwork that turns a claim into money at the closing table.
What counts as an add back
Start with anything on the P&L below revenue that is personal to you or will not happen again under a new owner. The usual list:
- Owner compensation. Your salary, payroll taxes on it and any distributions run through payroll.
- Owner benefits. Health insurance, retirement contributions and other benefits that cover only you and your family.
- Vehicles. A truck or car that is yours, not the fleet’s.
- Travel and meals. Trips and dinners that were personal, or that a new owner would not take.
- One time professional fees. A lawsuit, a restructuring, a consultant brought in for a single project.
- Other one time costs. A move, a storm repair, a home project that was paid by the business.
If you are wondering whether you are the only owner who does this, you are not. Our advisors see personal legal costs, family expenses and home projects in the books all the time. Nobody is shocked by it. What matters is whether you can show it.
What does not count
The most common misconception we hear is that every personal expense is an add back. Most of them are fine, but not all.
Costs the buyer still has to pay. A phone plan the whole team uses, a software subscription the business runs on, a vehicle a manager drives every day. If the cost continues after you leave, it stays in the numbers. Small recurring items are where most owners overreach.
Bad decisions dressed up as one time costs. One owner carried two sales hires and an expansion into a new territory for two years with little to show for it, then presented all of it as add backs. A buyer does not read that as a one time cost. A buyer reads it as an owner who was not watching the cost line, and starts asking what else was missed. A weak add back can cost you more trust than it adds in earnings.
Anything that ties the buyer to something you want to keep. An owner who started a new service line inside the same company shortly before selling learned that any buyer would expect it to come with the deal, along with a non compete. If you want to keep a side venture, separate it into its own entity before you go to market, not during diligence.
The documentation standard buyers and lenders accept
An add back is a claim until it is backed by paper. Lenders treat an undocumented add back as zero, and many discount add backs even when the explanation is good. So document every one:
- Bank and credit card statements that show each expense, line by line.
- A short written reason for each item: what it was, why it is personal or one time, and why it will not continue.
- A bridge from the tax return. Lenders underwrite from your filed returns, not your internal P&L. Every adjusted number has to start from the return and walk to the final figure.
That last point is where many deals stall. When a buyer says “the tax returns do not tie to the P&L,” there is often a real story: an insurance recovery, an entity change or a one time loss. The right response is the explanation and the evidence, not a defense of the number. Where the books genuinely do not tie, fix it before a lender sees it.
Filing matters too. We have seen an owner fall behind on a current year tax return while running the business flat out. The valuation work could start from prior years, but nothing could go in front of buyers until the return was filed, because the lender needs it. You cannot sell what the bank cannot see.
Why a weak add back costs more than it adds
Every add back is multiplied by the multiple a buyer is paying. That works for you when the add back holds and against you when it does not.
On one small business, the buyer and the advisor looked at the same P&L and landed six figures apart on cash flow. The buyer deducted a salary for the role they would fill, accepted only part of the meals, travel and auto add backs, and kept the owner benefits as a business cost. Multiplied out, that gap was the whole deal, and it did not close.
Expect a buyer to do the same math. They will replace your salary with a market rate for the role you fill, not what you need to live on. They will treat benefits that cover only your family as yours, not the business’s, but only if you show it. And their lender will be more conservative than they are. The add backs that survive are the ones that were documented before anyone asked.
Messy books are fixable
If your books are messy and you run a lot through the business, you are in good company. The fix is not to stop and wait a year. It is to get the evidence in order:
- Tie your P&L to your tax returns for the last three years.
- Pull statements for every add back and write one line on each.
- Drop the small recurring items that will not survive. Conservative numbers that hold are worth more than aggressive numbers that collapse in diligence.
- Look at any big swing in margin from year to year and write down why it happened, before a buyer asks.
An illustrative SDE example
The figures below are illustrative only. They are not from any client and are here to show how add backs build seller’s discretionary earnings (SDE), and what happens when one fails.
| Line | Amount |
|---|---|
| Net income on the tax return | $310,000 |
| Owner salary and payroll taxes | $150,000 |
| Owner and family health insurance | $18,000 |
| Personal vehicle | $14,000 |
| One time legal fees (documented) | $22,000 |
| Personal travel and meals | $9,000 |
| Depreciation | $25,000 |
| Interest | $12,000 |
| SDE | $560,000 |
Two lines are missing on purpose. A $6,000 software subscription the team uses every day is not added back, because a new owner still pays it. And if the $22,000 in legal fees had no invoices or statements behind it, a lender would treat it as zero, and SDE would drop to $538,000. That $22,000 is then lost again at every turn of the multiple.
The short version
Add back what is personal or one time. Leave out what the buyer still pays. Prove every line with bank and credit card statements, and make sure it all bridges from your tax returns. Do that work before you go to market and the add backs you are owed show up in the price.

Frequently asked questions
Which of my expenses count as add backs?
Anything on the P&L that is personal to you or will not happen again under a new owner: your own salary and payroll taxes, benefits that cover only you and your family, a personal vehicle, personal travel and meals, and one time costs such as a lawsuit, a move or a consulting project. Small recurring costs that a buyer would still have to pay usually do not count.
Is every personal expense an add back?
No. Most personal expenses are fine to add back, and nearly every owner runs some through the business. But if the cost would continue under a new owner, such as a phone plan the team uses or a software subscription the business depends on, a buyer will not accept it. And any add back you cannot document is treated as zero.
What documentation do buyers and lenders accept for add backs?
Bank statements and credit card statements that show each expense, plus a short written explanation of why it will not continue. Lenders underwrite from tax returns, so every add back needs to bridge cleanly from the return to the adjusted number. A claim with no paper behind it does not count.
My books are messy and I run personal expenses through the business. Is that a problem?
The fact of it is not a problem; it is common. The problem is evidence. Clean up and document before you go to market: tie the P&L to the tax returns, pull statements for each add back, and be ready to explain any large swing in margin before a buyer asks.
Why does a buyer calculate a lower cash flow number than my advisor?
Usually because of three things: the buyer deducts a market rate salary for the role you fill, accepts only part of the travel, meals and auto add backs, and keeps some owner benefits as a business cost. Expect a gap and work through it line by line with documentation.
What if my tax returns do not match my P&L?
There is often a real reason, such as an insurance claim, an entity change or a one time loss. Explain it with evidence rather than defending the number. If the books truly do not tie, fix that before a lender sees them, because lenders underwrite from the returns.
What is the difference between SDE and adjusted EBITDA?
Seller's discretionary earnings (SDE) adds back the full owner salary and is used for smaller, owner run businesses. Adjusted EBITDA deducts a market rate salary for the owner's role and is used once a business has management in place. Both start from the same documented add backs.
