Morning: Small Business Tax Tips (New Haven): The De Minimis Safe Harbor, The $2,500 Written Policy New Haven Business Owners Should Adopt Before December 31

New Haven, Connecticut | Jose’s Tax Service | October 12, 2026

For a small business, the federal de minimis safe harbor can allow qualifying lower-cost tangible property to be deducted when purchased rather than capitalized and depreciated. The limit is generally $2,500 per invoice or item for businesses without an applicable financial statement (AFS), and $5,000 for those with one.

The timing of the accounting policy matters. For a calendar-year business seeking to use the safe harbor for 2026 purchases, its qualifying accounting procedure must have been in place on January 1, 2026. A policy adopted now, before December 31, does not retroactively qualify earlier 2026 purchases. Adopt or confirm a written policy by December 31, 2026 for consistent use beginning January 1, 2027.

What the Safe Harbor Does!

Under Treasury Regulation §1.263(a)-1(f), a business that meets the requirements may elect to deduct qualifying costs to acquire or produce tangible property, instead of capitalizing those costs for federal tax purposes.

The safe harbor is a tax election, not a blanket rule that every small purchase is deductible. To qualify:

• Without an AFS: The item’s cost must be no more than $2,500 per invoice or item, and the business must have an accounting procedure or policy in place at the beginning of the tax year and treat the cost as an expense in its books and records.
• With an AFS: The amount may be up to $5,000 per invoice or item. The business must have written accounting procedures in place at the beginning of the year and expense the item on its AFS under those procedures.

An AFS generally means a qualifying financial statement, such as a financial statement filed with the Securities and Exchange Commission or a certified audited financial statement. Most small businesses do not have one, but confirm your status with your accountant before applying the $5,000 limit.

The dollar test applies per invoice or per item as substantiated by the invoice. It is not a general limit on all purchases made from one vendor or during the year. These thresholds determine eligibility for this safe harbor; they do not cap other deductions that may be available under tax law.

Put the Policy in Place Before the Tax Year!

For 2026, the relevant accounting procedure needed to exist when the tax year began. That is why the year-end action now is to prepare for 2027, not to backdate a policy for 2026.

Adopt and sign a written policy by December 31, 2026. While a business without an AFS is not required to have the procedure in writing, a dated written policy creates a clear record of the standard being applied. Specify:

1. The applicable per-item or per-invoice limit.
2. That qualifying items at or below the limit are expensed in the books.
3. How invoices are reviewed and retained.
4. Who approves purchases and records them.
5. How the policy is applied consistently throughout the year.

Do not create a policy now and treat it as effective from January 1, 2026. Ask your tax preparer how to handle purchases already made this year if no qualifying procedure was in place.

Make the Annual Election on the Federal Return!

The accounting policy and the tax election are different steps. The policy must be in place at the start of the tax year. The annual election is generally made later by attaching a statement titled “Section 1.263(a)-1(f) de minimis safe harbor election” to the timely filed original federal income tax return, including extensions.

The election applies to all expenditures for that year that meet the safe-harbor requirements. It is not a way to select only favorable invoices. Coordinate the statement with your tax preparer and retain a copy with your return records. The IRS’s tangible property final regulations provide further guidance.

Do Not Confuse This With Section 179 or Bonus Depreciation!

The de minimis safe harbor is distinct from Section 179 and bonus depreciation.

• De minimis safe harbor: An annual election for qualifying items within the per-invoice or per-item limit, supported by the business’s accounting policy and book treatment.
• Section 179: A federal expensing provision for certain qualifying property, subject to eligibility rules and limits.
• Bonus depreciation: A federal first-year depreciation deduction for eligible property, subject to applicable acquisition and placed-in-service rules.

Items above the safe-harbor limit do not automatically qualify for Section 179 or bonus depreciation. They must be reviewed under the applicable rules. For eligible property, having it placed in service by December 31, 2026 may affect whether it is treated as 2026 property. That is a separate consideration from the de minimis election, and it does not make every purchase deductible.

Connecticut treatment also requires attention. Connecticut generally requires adjustments for federal bonus depreciation and Section 179 deductions; the federal deduction may not carry over unchanged to a Connecticut return. For corporations, review the applicable Connecticut Form CT-1120 instructions. For individuals and pass-through business owners, consult the current Connecticut return instructions and DRS state tax developments. Confirm the rules for your entity and tax year with your preparer.

Separate Repairs From Capital Improvements!

The safe harbor does not replace the general rules for repairs and improvements. Under Treasury Regulation §1.162-4, qualifying repairs and maintenance may be deducted. Under §1.263(a)-3, costs must generally be capitalized when they improve a unit of property through a betterment, restoration, or adaptation to a new or different use.

For example, routine work that keeps equipment operating may be a repair. A substantial upgrade that materially increases capacity or replaces a major component may need to be capitalized. The answer depends on the facts, the relevant unit of property, and the nature of the work, not simply on the invoice total.

Connect the Policy to Bookkeeping and Asset Records!

A New Haven business should make the policy part of its regular bookkeeping workflow. For each purchase, retain the invoice, record the vendor, date, business purpose, item description, and cost, and note whether the item was expensed under the policy or reviewed for capitalization.

Keep a separate log for significant property and improvements, even when some lower-cost items are expensed. That record helps the preparer distinguish routine repairs, capital improvements, and property potentially eligible for depreciation. Do not split an invoice or alter an invoice description to fit the threshold.

Apply the policy consistently from the start of the tax year. A sound workflow is:

1. Date and sign the written policy before January 1, 2027.
2. Apply the policy consistently to qualifying purchases throughout 2027.
3. Keep invoices and receipts with clear business-purpose notes.
4. Log significant assets and improvements in the bookkeeping records.
5. Give the policy, invoices, and asset log to your tax preparer when preparing federal and Connecticut returns.

Mark the Year-End and Payment Dates!

For a calendar-year business, December 31, 2026 is the year-end date to review eligible property placed in service during 2026 and finalize the written policy for 2027. Do not treat the placed-in-service deadline as a substitute for checking eligibility or the Connecticut adjustments.

For individuals with income not subject to sufficient withholding, the fourth 2026 federal estimated tax installment is generally due January 15, 2027. Review the official 2026 Form 1040-ES and confirm whether you need to pay. Business entity payment schedules may differ.
