It's often best to use both, applying Section 179 first for specific assets (like real property improvements or to control income) and then using bonus depreciation for remaining assets, especially for large purchases or to create a Net Operating Loss (NOL). Section 179 offers flexibility and income limits, while bonus depreciation (currently 60% in 2024) is automatic, has no spending cap, and can create losses, making the choice dependent on your business's income, purchase size, and tax goals.
What is the difference between bonus depreciation and section 179? While bonus depreciation and Section 179 are both immediate expense deductions, bonus depreciation allows taxpayers to deduct a percentage of an asset's cost upfront. In contrast, Section 179 allows taxpayers to deduct a set dollar amount.
Con: you cannot use that asset's depreciation again in the future, so you have to consider the potential value of the deduction in the future. Generally, it's best not to have major swings in income as it makes it more difficult to manage tax rates on an annual basis.

To avoid the 22% tax bracket (or any higher bracket), focus on reducing your taxable income through strategies like maxing out 401(k)s and HSAs, deferring bonuses, tax-loss harvesting, smart charitable giving, and strategic asset location, understanding that higher rates only apply to income within that bracket, not your entire income.
If the vehicle weighs more than 6,000 pounds and is used more than 50% for business, you can write off up to $28,900 in the first year, and potentially even more with bonus depreciation. Let's break it down: Buy a qualifying vehicle for $60,000, and you could write off a large portion of that cost in year one.
Electing out will allow you to offset the higher income with more depreciation expense in the later years. If you plan to sell the purchased property in a year in which you are in a higher tax bracket, any depreciation recapture would be taxed at the higher rate.
Expensing an item may bring in more money in the short term, but once you have expensed it, it does not qualify for write-offs on future tax returns. Depreciating an asset may result in less money upfront, but could result in fewer taxes owed in the future.

As a business owner, you can deduct the cost of a computer that you use in your business or for business-related purposes. While sometimes a business owner can deduct the cost in a single year, they may need to spread the cost over multiple years in some cases.
Other landlords worry that claiming depreciation could result in lower income from their property, reducing their cash flow. However, depreciation isn't an actual cash expense; it's simply a tax deduction. In other words, depreciation may lower your taxable income, but it doesn't affect your cash flow.
