Founder equity and US tax process

83b Election for Non US Founders

A Delaware corporation can issue founder equity quickly, but the federal clock follows the equity event, not incorporation. This guide to 83b election for non US founders helps identify the transfer date, distinguish shares from award rights, and preserve a filing record. It is educational, not individualized tax or legal advice.

83b election for non US founders appears above founders reviewing equity records.

What should a non-US founder check before making an 83(b) election?

An 83b election for non US founders may matter when actual, substantially nonvested stock is transferred for services. The deadline follows that transfer, not Delaware formation. Eligibility, income, withholding, and filing details depend on the award, taxpayer, service location, residency, and transaction records.

  • Identify the date actual property was transferred under signed equity documents.
  • Confirm whether the award is restricted stock, an option, or an RSU right.
  • Resolve taxpayer identification, mailing, and cross-border questions before filing.

Start With the Transfer Date

For an 83b election for non US founders, the operative date is the date property was transferred to the service provider. Incorporation, board approval, a founder agreement, and issuance can happen on different days. Review the stock agreement, exercise notice if relevant, board consent, capitalization record, and vesting or repurchase terms. Do not assume the incorporation certificate proves a stock transfer.

The IRS says the election must be filed no later than 30 days after transfer. When day 30 falls on a Saturday, Sunday, or legal holiday, the current instructions apply the next-business-day postmark rule. Record the date used, calendar day 30, and set an earlier mailing target. How to file 83b election for startup is a document-and-deadline question before it is a form question.

Classify the Award Before Filing

Restricted stock is not the same as an unexercised option or an RSU. The IRS revenue procedure addresses substantially nonvested property transferred for services, such as shares subject to forfeiture risk. The restricted stock 83b election checklist starts with evidence that shares were transferred, not merely that an award was promised.

Revenue Procedure 2012-29 explains that Section 83 generally does not apply to an option without a readily ascertainable fair market value at grant. If substantially nonvested property is received on exercise, the relevant transfer may occur on exercise. For an RSU, inspect whether property transferred at all and how settlement works. Ask qualified counsel or a tax adviser to apply the rules to the award.

Use a Transfer-Triggered Workflow

83b election deadline after stock transfer captures the core control: start the clock when the documented transfer occurs. Keep the date, share quantity, amount paid, restrictions, and fair-market-value support with the signed equity documents. A reminder system helps only when someone verifies its inputs.

For delaware incorporation 83b deadline automation, trigger a task from stock issuance or option exercise, not formation. Assign a reviewer and preserve the signed election and mailing evidence. Automation cannot decide whether property is substantially nonvested, establish value, or determine a founder’s tax result.

  • Freeze the transaction facts: Save the agreement, transfer or exercise date, quantity, price, restrictions, approvals, and valuation support.
  • Prepare Form 15620 data: Collect the taxpayer’s name, TIN, address, taxable year, property, transfer date, restrictions, value, amount paid, and income amount.
  • Confirm mailing and proof: Mail as Form 15620 directs, then retain signed copies, a scan, and postmark or tracking evidence.

Treat Non-US Status as a Fact Pattern, Not an Exemption

An 83b election for non US founders is not automatically required or unavailable because a founder lives abroad. US residence, service location, entity, compensation facts, treaty positions, and local law can change the analysis. Get cross-border advice rather than rely on a generic workflow.

83b election tax withholding for nonresidents is separate. An election addresses timing of income inclusion for qualifying property; it does not automatically eliminate payroll, wage-reporting, or withholding obligations. The company and founder should have suitable advisers assess the actual facts.

Form 15620 asks for the taxpayer’s name, taxpayer identification number, and address. Do not invent, borrow, or substitute an SSN. If you lack a valid TIN or do not know the applicable identification or filing profile, obtain qualified US tax guidance. An entity identifier is not a personal taxpayer identifier.

Complete, Mail, Share, and Retain

Form 15620 is an IRS convenience form; its instructions describe a written statement meeting the Treasury regulation as an alternative. The form requests the property and quantity, transfer date, taxable year, restrictions, fair market value, amount paid, and income amount. Box 9 is optional, but transaction facts should not be estimated.

Mail the completed, signed form to the IRS office where you file a federal income tax return. Send a signed copy to the person for whom services are performed. If you, the person performing the services, are not the transferee of the property, send a signed copy to the transferee too. Keep your signed election and mailing evidence.

The older revenue procedure’s sample refers to attaching a copy to the transfer-year return, while current Form 15620 emphasizes mail filing and additional copies. Ask a qualified adviser whether an attachment or other reporting is currently required for your facts.

Understand the Election Before You Sign

The IRS describes the election as including the excess of fair market value at transfer over the amount paid, rather than waiting for later vesting. It may create current income, and revocation generally requires IRS consent under restrictive rules. It does not assure a favorable tax outcome. Nonresident founder 83b tax planning should assess liquidity, residency, downside, and local consequences before signing.

“An 83(b) election must be filed no later than 30 days after the date the property was transferred.”

Questions founders ask next

Does Delaware incorporation start the 30-day period?

No. The deadline is measured from the property-transfer date. Formation starts it only if it is also the documented transfer date.

Can I elect for founder stock that is already vested?

IRS materials address substantially nonvested property transferred for services. Obtain advice if the shares are vested or the facts are unusual.

Can I file for an option before exercising it?

Not routinely. The IRS describes a narrow readily-ascertainable-value rule; on exercise into substantially nonvested property, the relevant transfer may instead be the exercise.

What if I am a nonresident and do not know my TIN?

Do not create or borrow a number. Form 15620 asks for the taxpayer’s TIN; obtain individualized guidance on identification and filing obligations.

Does filing remove company withholding obligations?

No automatic result follows. Withholding, wage reporting, payroll, and non-US tax issues depend on the facts and need separate review.

What copies should I keep and send?

Keep the signed election and timely-mailing proof. Form 15620 directs copies to the service recipient and, in the stated case, the transferee.

Your next step

A careful 83b election for non US founders starts with a documented property transfer, not formation. Before meeting your adviser, assemble the equity agreement, transfer date, amount paid, restrictions, valuation support, and personal filing details. Ask for a filing decision, mailing destination, and copy checklist; then assign an owner to preserve timely-mailing proof.

After documenting the equity filing decision, establish a calendar for Delaware annual-report, franchise-tax, and corporate-record obligations. Keep Delaware filings and franchise-tax obligations on track.
