Form a US LLC from South Africa

As a non-resident without a US SSN or ITIN, you apply for an EIN via Form SS-4 by fax, listing 'Foreign' as your responsible party's identification. Expect 4-7 business days for fax processing once the IRS confirms receipt. South African founders occasionally hit a snag here because South African ID numbers are sometimes mistakenly entered into fields meant for a US SSN format -- leave that field for foreign applicants blank or marked 'Foreign' exactly as instructed, don't substitute your SA ID number.

Mercury and Relay both accept South African applicants once your LLC and EIN exist, with no US visit needed. For actually moving money between South Africa and your US LLC, most founders use their bank's standard SDA-linked offshore transfer process for smaller amounts, and Wise for day-to-day USD/ZAR conversions on operating expenses -- it's usually cheaper than a traditional SWIFT transfer through a South African bank for amounts under the SDA threshold. Keep transfer records; SARS occasionally asks for supporting documentation on offshore transfers years after the fact, and reconstructing them retroactively is painful.

Wyoming and Delaware split South African founders roughly the way they split everywhere else: Wyoming for cost-conscious bootstrapped businesses ($60/year, no franchise tax), Delaware for anyone building toward institutional investment, since South African and international VCs alike default to expecting Delaware structures. If you're a fintech founder given Cape Town and Johannesburg's growing fintech scenes, Delaware is worth the extra cost -- investors in that specific vertical rarely blink at Delaware and sometimes ask questions about anything else.

Wyoming's annual report and $60 fee are due by the first day of your formation anniversary month. Delaware's franchise tax (up to $400 under 2026 rates) is due June 1 every year. Federally, Form 5472 and the pro-forma 1120 are due April 15, with an automatic extension to October 15 via Form 7004. If you used the FIA for any transfers, keep your AIT tax clearance documentation on file -- SARS and SARB can both request it well after the transfer itself took place.

South Africa is one of the few countries in this Cluster A batch with an actual US tax treaty in force, dating to 1997. For a disregarded single-member LLC with no US trade or business, that treaty mostly matters for withholding-rate reduction on specific categories of US-source income rather than for the baseline disregarded-entity filing, which still requires Form 5472 plus a pro-forma Form 1120 annually regardless of income -- missing it risks the standard $25,000 minimum penalty. On the South African side, any US-source income the LLC's owner personally receives (as opposed to income retained in the LLC) may need to be declared to SARS depending on your residency and tax status; South African tax residents are taxed on worldwide income, so this isn't purely a US-side concern.

South Africa is the one country in this batch where the first real question isn't about the IRS -- it's about the South African Reserve Bank (SARB). South Africa runs exchange controls on its own residents (not on non-residents, which trips up some founders who read the wrong section of a guide). Every South African resident gets a Single Discretionary Allowance (SDA) of R1 million per calendar year that can be moved offshore without SARB approval or tax clearance -- just report it through your bank. Beyond that, a Foreign Investment Allowance (FIA) of up to R10 million per year is available, but requires an AIT (Approval International Transfer) tax clearance certificate from SARS first, confirming your tax affairs are in order. Funding your LLC's initial formation costs and early operating expenses almost always fits comfortably inside the SDA. It's only once you're moving profits back and forth at meaningful scale, or capitalizing the LLC heavily upfront, that the FIA and its tax-clearance requirement become relevant -- worth planning for before you need it, not after.
