The fixed asset register nobody keeps (and what it costs)

Ask most owners what depreciation was last year and they can find the number. Ask what it consists of and the answer is usually that the accountant works it out.

That is a missed opportunity rather than a crisis. A fixed asset register is a simple list, and keeping it answers questions that matter well beyond the tax return.

What it is

One row per asset: what it is, when you bought it, what it cost, its useful life, depreciation to date, and what is left. Ten columns in a spreadsheet, or a built-in module in most accounting systems.

Fully depreciated does not mean worthless

The forklift carries $0 on your balance sheet and lifts things every day. Accounting has finished with it; the business has not.

This matters in two directions. Your balance sheet understates what you own, which is worth knowing when a lender or a buyer is assessing you. And more importantly, an asset at zero book value is one whose replacement is entirely unfunded — the depreciation that was notionally setting money aside has stopped, and the machine has not.

It tells you next year's capital spending

This is the real management use. Sort by remaining life and you have a replacement calendar. The van has a year left; the CNC machine two. That is $174,000 of replacement cost arriving over three years, and it is visible today.

Businesses that skip this discover their capital requirement when something stops working, which is the most expensive possible moment — no time to shop, no time to arrange financing, and whatever is available at the price it happens to be.

Depreciation is not a savings account

Worth being precise here, because the intuition misleads people. Depreciation spreads a cost you already paid across the years the asset serves. It does not set cash aside; no money moves.

So a business showing healthy profit after depreciation has covered the historic cost of its assets in its reported earnings — but unless someone deliberately reserved cash, the money to replace them is not anywhere. This is why an EBITDA-managed business can look strong and still be unable to fund the equipment it runs on.

Three habits, ten minutes a quarter

• Record additions as they happen with the date placed in service, not the invoice date — that date drives both depreciation and the tax treatment.
• Record disposals. The most common register error is assets that were scrapped or sold years ago still sitting on the books, quietly overstating your assets and your depreciation.
• Review remaining life annually, at planning time, and put the replacements into next year's cash forecast.

Your accountant maintains a version of this for tax, and it will differ from yours because tax lives and book lives are not the same. That is expected. Yours exists to answer management questions; theirs exists to file a return.
