If you rent every tool you use, this article is not for you. Rental is an ordinary expense and none of this applies.

A subcontractor buys a mitre saw for $1,800 and a generator for $2,200, and is told both must be depreciated because they will last more than a year.

That is the general rule. It is also not the only one available, and the alternative is an election most trades have never heard of.

The short answer

Purchase Under the safe harbor
$180 impact driver Deducted in full this year
$1,800 mitre saw Deducted in full this year
$2,200 generator Deducted in full this year
$2,500 compressor Deducted in full this year
$2,600 trailer Over the line — depreciate, or use another provision
Invoice of $9,000 for six tools at $1,500 each Each item qualifies, as substantiated by the invoice

What the safe harbor is

The tangible property regulations let you elect to treat small purchases the way your books already treat them — as an expense — rather than capitalising them.

The IRS states the threshold and its history in one place:

"Effective for taxable years beginning on or after Jan. 1, 2016, the Internal Revenue Service in Notice 2015-82 increased the de minimis safe harbor threshold from $500 to $2500 per invoice or item for taxpayers without applicable financial statements."

And the two tiers:

"If you have an applicable financial statement (AFS), you may use this safe harbor to deduct amounts paid for tangible property up to $5,000 per invoice or item (as substantiated by invoice). If you don't have an AFS, you may use the safe harbor to deduct amounts up to $2,500 … per invoice or item (as substantiated by invoice)."

An applicable financial statement is broadly an audited statement or one filed with a government agency other than the IRS or SEC. If you are a one-person trade, you do not have one, and $2,500 is your number.

Note per invoice or item. A single invoice for six tools at $1,500 each is not one $9,000 purchase — each item stands on its own where the invoice substantiates it.

The condition that has to happen before January

This is the part that costs people the election, and it is the reason to read this in December rather than April:

"If you don't have an AFS, you are not required to have written accounting procedures; however, you must expense amounts on your books and records for the taxable year in accordance with a consistent accounting procedure or policy existing at the beginning of the taxable year."

Two things there, and they pull in different directions.

The relief: no written policy is required for a business without an applicable financial statement. That is a genuine simplification, and plenty of advice still insists on a written one because larger businesses need it.

The condition: the policy has to exist at the beginning of the taxable year. Deciding in March how you will treat a saw you bought in January does not meet it. The policy predates the year; the purchases follow it.

One paragraph, written in December"For the tax year beginning 1 January, this business deducts as an expense any item of tangible property costing $2,500 or less per invoice or item." Date it, keep it, and the following year is settled. It is not required in writing — but it costs a minute and removes the argument about when the policy existed.

Making the election

It is annual, and it is made on the return:

"…attaching a statement to a timely filed original federal tax return including extensions… name, address, and Taxpayer Identification Number, as well as a statement that you are making the de minimis safe harbor election."

Two consequences worth knowing before you elect:

"Under the election, you must apply the de minimis safe harbor to all expenditures meeting the criteria for the election in the taxable year."

All of them. You cannot expense the tools you want expensed and capitalise the ones you would rather depreciate for a better result elsewhere.

"An annual election is not a change in method of accounting. Therefore, you should not file Form 3115… to use the de minimis safe harbor for a particular tax year, and you should not file a Form 3115 to change the amount you deduct under your book policy. Similarly, you should not file a Form 3115 to stop applying the de minimis safe harbor for a subsequent tax year."

So it is a light-touch decision. Elect this year, do not elect next year, change your book threshold — none of it requires the change-of-method machinery.

Above the line

A policy over $2,500 is not forbidden, it is just outside the safe harbor's protection:

"If you don't have an AFS and have a policy for your books and records of deducting amounts more than $2,500…, you may properly deduct these amounts for federal tax purposes, as long as you can show that…"

You keep the ability to argue the treatment; you lose the certainty that removes the argument. For a trade buying tools in the $200 to $2,500 band, the safe harbor covers almost everything anyway.

And for genuinely large purchases — a truck, a trailer, a machine — the safe harbor was never the right tool. Section 179 and bonus depreciation are where those belong, and they are separate elections with their own limits.

What to do

  1. Write the paragraph now, dated before the year you want it to cover.
  2. Expense qualifying items in your books during the year, consistently with it.
  3. Keep invoices that show per-item pricing. "Per invoice or item, as substantiated by invoice" means the invoice has to show the breakdown.
  4. Attach the election statement to the return, on time, every year you want it.
  5. Leave the large assets out of this and handle them under section 179 or bonus depreciation.

The difference between a trade that does this and one that does not is not the total deduction over a decade — it is having it now, on the tools you already paid for.

Track it now. Thank yourself in April.

Common questions

How much can I deduct outright per tool?
Up to $2,500 per invoice, or per item as substantiated by the invoice, if you have no applicable financial statement. The IRS raised it from $500 with Notice 2015-82, effective for tax years beginning on or after 1 January 2016.
What is an applicable financial statement?
Broadly, an audited financial statement or one filed with a federal or state agency other than the IRS or SEC. Almost no independent subcontractor has one — which is why $2,500 is the number that applies to you, not the $5,000 that applies to businesses that do.
Do I need a written policy?
Not if you have no applicable financial statement. The IRS says so directly: "If you don't have an AFS, you are not required to have written accounting procedures; however, you must expense amounts on your books and records for the taxable year in accordance with a consistent accounting procedure or policy existing at the beginning of the taxable year."
So what does "existing at the beginning of the taxable year" mean for me?
That the policy has to predate the year, not the purchase. Deciding in March how you treated a January saw does not satisfy it. Writing one paragraph in December costs nothing and settles the following year.
How do I actually make the election?
By attaching a statement to a timely filed original return, including extensions, with your name, address and taxpayer identification number and a statement that you are making the de minimis safe harbor election. It is made year by year.
Can I pick and choose which tools it applies to?
No. "Under the election, you must apply the de minimis safe harbor to all expenditures meeting the criteria for the election in the taxable year." It is all of them or none of them.
Do I file Form 3115 to start or stop using it?
No. "An annual election is not a change in method of accounting", so Form 3115 is not used to start it, to change your book threshold, or to stop applying it in a later year.
My book policy is higher than $2,500. Is that a problem?
It falls outside the safe harbor, which does not automatically make it wrong — the IRS says you may still properly deduct those amounts if you can support the treatment. You just lose the certainty the safe harbor buys.
