What Are Tax Elections and How Do They Work?

Tax elections are formal choices the Internal Revenue Code lets you make to override the default way a transaction, income stream, or business entity gets taxed. They work on a simple mechanic: the code sets a default rule, and if you want a different result, you file a specific form by a specific deadline. Do nothing, and the default applies. File on time, and you lock in the alternative, often for years.

That permanence is what makes elections worth understanding before you need one. Most bind you for the year they cover, and many bind you well beyond. You generally cannot reverse the choice just because your circumstances change or you realize later that the other option would have saved more money. The elections below are the ones that affect the most taxpayers and carry the highest stakes.

Elections That Change How Your Business Is Taxed

S Corporation Status

The single most impactful structural election for small businesses is choosing S corporation treatment. By default, a corporation pays its own income tax, and shareholders pay tax again when profits are distributed. An S corporation avoids that double layer: income, losses, deductions, and credits flow through to shareholders’ personal returns. The election is made on Form 2553.¹

The deadline is tight. Form 2553 must be filed no later than two months and 15 days after the start of the tax year the election should take effect, or at any time during the preceding tax year.² For a calendar-year corporation, that means March 15. Miss it and the company defaults to C corporation taxation for the entire year. The form can be submitted by mail or fax, not through IRS e-file.

LLC Entity Classification

Limited liability companies get unusual flexibility. An LLC does not have a fixed tax classification; it picks one. A single-member LLC can elect to be taxed as a disregarded entity or as a corporation. A multi-member LLC can elect partnership or corporation treatment. The election is made on Form 8832.³

If the LLC files nothing, a default kicks in: single-member LLCs are treated as disregarded entities, and multi-member LLCs as partnerships.⁴ That default works fine for many businesses. An LLC that wants corporate taxation, often as a stepping stone to an S election, needs to file Form 8832 affirmatively.

Elections That Change When You Deduct or Recognize Income

Section 179 Expensing

Section 179 lets you deduct the full purchase price of qualifying business assets in the year you buy them, rather than depreciating the cost over the asset’s useful life. For 2026, the maximum deduction is $2,560,000, phasing out once total qualifying purchases exceed $4,090,000.⁵ The election is made on Form 4562, filed with your return, on an asset-by-asset basis. The deduction cannot exceed your business’s taxable income for the year, so it cannot create or increase a net loss.

Bonus Depreciation

Bonus depreciation runs alongside Section 179 with different mechanics. Under the One Big Beautiful Bill Act, businesses can permanently deduct 100 percent of the cost of qualifying property in the first year it’s placed in service, for assets acquired after January 19, 2025.⁶ Unlike Section 179, bonus depreciation can generate a net operating loss.

The election here runs in the opposite direction from what you might expect. Full bonus depreciation is the default; you elect to take less. You can elect 40 percent instead of 100 percent (60 percent for long-production-period property and certain aircraft), or opt out for any class of property.⁶ Opting out makes sense when you expect higher tax brackets in future years and want to preserve deductions for when they’ll save more.

Accounting Method

Your accounting method controls when income and expenses show up on your return. Under the cash method, you report income when payment is received and deduct expenses when paid. Under accrual, income is recognized when earned and expenses when incurred, regardless of cash movement.

Most small businesses prefer cash accounting because of the timing flexibility: delay an invoice until January, prepay a deductible expense in December. Any business can use the cash method as long as its average annual gross receipts over the prior three years stay below an inflation-adjusted threshold, which has been around $31 million in recent years.⁷ Once you’ve been filing under one method, switching requires Form 3115, and some changes need advance IRS approval before they take effect.⁸

Elections on Your Personal Return

Standard Deduction or Itemizing

The election most taxpayers encounter every year is whether to claim the standard deduction or itemize. The standard deduction is a flat amount based on filing status: for 2026, it’s $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.⁹ Itemizing lets you deduct specific expenses like mortgage interest, state and local taxes, and charitable contributions, but only makes sense when those expenses exceed the standard deduction.¹⁰ This choice resets every year.

Foreign Tax Credit or Deduction

If you earn income from international investments and pay foreign taxes, you choose annually whether to treat those taxes as a deduction (which reduces taxable income) or as a credit (which reduces your actual tax bill dollar for dollar). The credit is almost always worth more. Claim it by filing Form 1116 with your return.¹¹ Like the standard-versus-itemized choice, this election is annual and can be changed freely.

Married Filing Separately

Married couples default to filing jointly, but they can elect to file separately. This is sometimes useful when one spouse has significant medical expenses, income-driven student loan payments, or potential liability concerns. The tradeoffs are steep. Filing separately disqualifies you from the earned income credit, education credits, and the student loan interest deduction. Your capital loss deduction drops from $3,000 to $1,500, and if one spouse itemizes, the other must also itemize.¹² Run the numbers both ways before committing.

The Section 83(b) Election

This is the election that startup employees and founders most often hear about, and the one with the least forgiving deadline in the entire tax code. When you receive restricted stock as compensation, the default rule taxes you on the stock’s value when it vests, at ordinary income rates. If the company’s value has grown between grant and vesting, the tax hit can be enormous.

A Section 83(b) election flips the timing. You pay tax on the stock’s value at the time of grant instead of at vesting.¹³ If the stock is worth very little at grant, common with early-stage startups, the upfront tax can be close to zero. Any future appreciation then qualifies for long-term capital gains treatment when you sell, provided you hold the shares for more than a year after the grant date.

The catch: you must file the election within 30 days of receiving the stock. No extensions, no exceptions.¹⁴ The election is irrevocable, so if the stock becomes worthless or you forfeit unvested shares, you cannot get back the tax you already paid.¹³ For most employees receiving stock in an early-stage company with a low valuation, the math still favors filing.

Real Estate Elections

Rental real estate income is generally treated as passive, meaning rental losses can only offset other passive income. The real estate professional election changes that. It lets you treat rental income as non-passive if you spend more than 750 hours per year in real property businesses in which you materially participate, and more than half of your total working hours are in those real estate activities.¹⁵ Hours worked as an employee in real estate generally don’t count unless you own at least 5 percent of the employer. Clearing this threshold lets you deduct rental losses against wages, business income, and other non-passive income.

A separate grouping election lets you combine multiple business or rental activities into a single activity for passive loss purposes, as long as they form an appropriate economic unit.¹⁶ Because the material participation test is applied per activity, combining smaller operations into one can make it easier to clear the hours threshold.

How You Actually File an Election

Most elections require a specific IRS form: Form 2553 for S corporation status, Form 8832 for entity classification, Form 4562 for depreciation elections, Form 15620 for Section 83(b). Some less common elections require only a statement attached to your return identifying the election, the applicable code section, and the tax year it covers. A missing signature or incomplete information can invalidate the election entirely.

Deadlines vary widely:

S corporation (Form 2553): two months and 15 days after the start of the tax year, or any time during the preceding year.²
Section 83(b): 30 days after the property transfer. No extension available.¹⁴
Standard deduction versus itemizing: due date of the return, including extensions.
Foreign tax credit versus deduction: due date of the return, including extensions.¹¹
Section 179 and bonus depreciation: due date of the return, including extensions.
Entity classification (Form 8832): up to 75 days before the requested effective date, with certain relief available within three years and 75 days.

“Timely filed” means postmarked or electronically submitted by the deadline. If the deadline falls on a weekend or holiday, the next business day counts.

If You Miss the Deadline

The IRS offers paths to fix a missed election, but none of them are pleasant enough to rely on as a strategy.

For late S corporation elections, Revenue Procedure 2013-30 provides a streamlined path that doesn’t require a private letter ruling or a user fee. The business must have intended to be an S corporation as of the effective date, and the only reason it doesn’t qualify must be the late filing. The request generally must be made within three years and 75 days of the intended effective date, or at any time if the corporation and all shareholders have filed every return consistent with S corporation status since the intended start date.¹⁷

When automatic relief isn’t available, you can request a private letter ruling asking the IRS to grant an extension of time under the Section 9100 regulations. The IRS will evaluate whether you acted reasonably and in good faith, including whether you reasonably relied on a qualified tax professional who failed to file. For requests received after January 29, 2026, the user fee is $14,500.¹⁸ The fee is non-refundable regardless of outcome, and approval is never guaranteed. The IRS will deny relief if it determines you knew about the deadline and simply chose not to act, or used hindsight to decide the election would be beneficial.

Which Elections You Can Change Later

Not all elections are equally permanent. Some reset every year. The standard deduction versus itemizing choice can alternate annually without IRS approval.¹⁹ The foreign tax credit versus deduction choice works the same way. These are elections that don’t fundamentally change your tax identity or reporting structure.

The more consequential elections are harder to undo. Revoking an S corporation election requires the consent of shareholders owning more than half the company’s stock, followed by a formal written statement filed with the IRS. Once revoked, the corporation cannot re-elect S status until the fifth tax year after the year the termination takes effect, unless the IRS grants special permission.²⁰

Changing your accounting method after you’ve been filing under one system requires Form 3115. Some method changes qualify for automatic consent procedures where the IRS grants approval as long as you follow the filing requirements; others go through a non-automatic process that resembles a letter ruling request.⁸

The Section 83(b) election sits at the extreme end: it’s irrevocable. You cannot undo it even if the stock drops to zero.¹³ That’s a feature of the election, not a bug: the IRS isn’t going to let you lock in a low tax bill on the upside and then claim a refund on the downside. Knowing which elections carry that kind of permanence before you file is the difference between tax planning and tax regret.
