Delaware flip is the conversion of a home-state LLC into a Delaware C-corp, and the only timing rule that matters is that it happens before the priced round closes. Everything else (which of the three Rev. Rul. 84-111 forms you use, whether your §1202 clock has started, whether your §83(b) election is still alive) is mechanics stacked on top of that one deadline.

Founders usually ask the flip question three months too late. The paperwork is tractable; the tax geometry underneath it is not, and the geometry hardens the instant a lead investor signs a term sheet.

How early is early enough

Before a priced round: mandatory. Every institutional lead will require Delaware C-corp stock, a clean cap table, and a charter with preferred authorized. If you show up to a Series A with a Wyoming LLC and a SAFE stack, the closing slips until you flip, and the flip now happens under deal-timeline pressure instead of on your own calendar.

Before a SAFE or convertible note: strongly preferred but not universal. Post-2018 YC SAFEs assume a C-corp (the SAFE itself says "Company" and expects stock), and most angels are fine signing a SAFE into an LLC only if there is an explicit conversion obligation. Where this bites is on convertible notes: interest accrues from the day of issuance, and if the note converts at a qualified financing while the issuer is still an LLC taxed as a partnership, that accrued interest is phantom income allocated to partners who never saw cash. Flipping before the trigger event avoids the K-1 surprise.

Twelve months before a planned exit: the §1202 reason. Qualified Small Business Stock under IRC § 1202 requires that the stock be originally issued by a domestic C-corporation and held for more than five years. The clock starts when the C-corp stock is issued, not when the LLC was formed. Every quarter you stay an LLC is a quarter of §1202 runway you are choosing to burn.

Tax-free, if you thread two needles

The flip is structured to be tax-free under two different Code sections, depending on the starting form.

If the entity is a multi-member LLC taxed as a partnership, the clean path is a §351 contribution: members contribute LLC interests (or, under an assets-over reading, the partnership contributes its assets) to a newly formed Delaware C-corp in exchange for stock, and the transferors end up in control as defined by § 368(c) (80% of voting power and 80% of every nonvoting class). Meet the control test and no gain is recognized at contribution, with a carryover basis to the corp and substituted basis to the stockholders under § 358.

If the LLC previously elected to be taxed as a C-corp and is merely redomesticating to Delaware, the conversion is an F reorganization under § 368(a)(1)(F), which the IRS has treated as a mere change in form since Rev. Rul. 57-276 and confirmed in the 2015 final regulations at Treas. Reg. § 1.368-2(m). F reorgs carry tax attributes (E&P, NOLs, method of accounting) across cleanly.

Single-member LLCs are the easiest case. A disregarded entity has no partnership-level tax existence, so there is no partnership to unwind; the owner is treated as contributing assets directly to the new corp under § 351, and Rev. Rul. 84-111 is a non-event.

The three forms of Rev. Rul. 84-111

For a multi-member LLC, Rev. Rul. 84-111 (1984-2 C.B. 88) blesses three mechanical paths, all tax-neutral at the federal level but not interchangeable in their downstream consequences.

Assets-over: the LLC contributes its assets and liabilities to the new corp in exchange for stock, then distributes the stock to its members and liquidates. This is the path most corporate lawyers default to because it produces the cleanest paper trail for asset-level issues (licenses, permits, customer contracts with anti-assignment clauses).

Assets-up: the LLC distributes its assets to members in a deemed liquidation, and the members then contribute those assets to the new corp. Rare in practice because the intermediate distribution creates transfer-tax and title-retitling exposure on any real estate or titled vehicles.

Interests-over: members contribute their LLC interests to the new corp, the LLC becomes a wholly owned subsidiary, and the corp then elects to treat it as disregarded (usually via a check-the-box on Form 8832) or liquidates it under § 332. This is the cleanest path when the LLC holds contracts that are hard to assign but can tolerate a change of indirect ownership.

Which form you pick shapes state-transfer-tax exposure, the §1202 original-issuance analysis (interests-over is the most defensible path for clean §1202 start dates), and whether founders receive restricted stock subject to vesting in the same transaction.

The §83(b) election is the silent killer

If the flip issues restricted stock to founders, or re-papers existing vested-over-time LLC units as restricted corp stock with a vesting schedule, each founder has thirty days from the date of transfer to file a § 83(b) election with the IRS under Treas. Reg. § 1.83-2(b). Thirty days. Calendar days. No extensions, no equitable tolling. Miss it and each vesting tranche is ordinary income at fair market value on the vesting date, which at a priced-round valuation is career-altering.

The clean practice is to prepare the §83(b) election letters in the same closing binder as the stock-purchase agreements and mail them certified with return receipt on closing day. Keep a scan. Two years later, when the IRS cannot find it, you will need the scan.

State tax does not care that you moved

Founders sometimes assume that flipping to Delaware means the home state stops taxing them. It does not. California, as the representative case, asserts franchise-tax jurisdiction over every corporation "doing business" in the state under R&TC § 23101, and the $800 minimum franchise tax under R&TC § 23153 applies to the new Delaware C-corp the moment it qualifies to do business in California. California-source income remains California-source income regardless of the entity's state of incorporation; § 25120 through § 25137 and the FTB's market-based sourcing rules under § 25136 decide that, not the charter.

A small number of states (notably California for individual residents under R&TC § 17951) also tax the gain a founder recognizes on a later sale of Delaware stock if the founder is a state resident on the date of sale. The flip does not move the founder's residence.

An exit tax at the LLC level on the conversion itself is uncommon but not impossible. Most states follow the federal characterization of § 351 and § 368(a)(1)(F) transactions and recognize no gain at the entity level; a handful have their own rules on deemed asset sales. Check before filing.

The timeline

Four to six weeks, assuming nothing is on fire. The Delaware Certificate of Incorporation is a day. Drafting the plan of conversion, the contribution agreements, the new charter with authorized preferred, and the restricted-stock purchase agreements is two to three weeks of coordinated corporate and tax work. The home-state dissolution or conversion filing (or statutory conversion, where available) runs in parallel. Cap-table rebuild in Carta or equivalent is a week. §83(b) filings go out on closing day. Expect another week of tail work for FinCEN and any state-level qualifications to do business.

If you are reading this with a term sheet in hand, you are already late; start the flip this week, assume the lawyers will quote six weeks, and assume you will need four. If you are a profitable single-member LLC with a possible exit in three to five years, flip now to start the §1202 clock, not later.

Rule of thumb: flip before the first priced dollar, ideally before the first SAFE, and always with §83(b) envelopes in the closing binder.
