What are the most common IRS tax mistakes?

What is the $2500 expense rule?

The $2,500 expense rule refers to the IRS's De Minimis Safe Harbor Election, allowing small businesses (without an Applicable Financial Statement (AFS)) to immediately deduct the full cost of qualifying tangible property up to $2,500 per item/invoice, instead of depreciating it over years, providing faster tax savings. If a business does have an AFS, the threshold is higher, at $5,000 per item/invoice. This election simplifies accounting for small purchases like computers, furniture, or even home improvements, but requires a consistent bookkeeping process and attaching the specific election statement to your tax return.
