Key Takeaways

  • Section 1446(f) focuses on transfers of partnership interests, not operating income allocations.
  • The base withholding rule is generally 10% of amount realized unless an exception applies.
  • A low gain number does not automatically mean low withholding exposure.
  • The partnership can still face consequences if the transferee fails to withhold.

Section 1446(f) is a sale-of-interest withholding rule, not an operating-income rule

The IRS partnership-withholding page explains that under section 1446(f)(1), a transferee generally must withhold 10% of the amount realized on a transfer of a partnership interest if any portion of the gain would be treated as effectively connected under section 864(c)(8), unless an exception applies. That is very different from section 1446(a), which is about partnership operating income flowing through to foreign partners.

The amount realized concept surprises founders

Because the rule is framed around amount realized, not just gain, people often underestimate the withholding exposure on a sale, redemption, or other transfer event. A founder may think, 'There is barely any gain,' while the withholding rule is looking first at the gross amount realized and then at whether an exception applies.

If the transferee misses the withholding, the partnership may inherit a problem

The IRS page also notes that under section 1446(f)(4), if the transferee fails to withhold the required amount, the partnership may have to deduct and withhold from distributions to the transferee the amount that should have been withheld, plus interest. That makes this a transaction-planning issue for the whole deal team, not just for the selling partner.

Frequently Asked Questions

Section 1446(a) applies to effectively connected taxable income allocated through the partnership, while section 1446(f) applies to transfers of partnership interests.

Who usually withholds under section 1446(f)?

The transferee or purchaser generally has the primary withholding obligation.

Can the partnership still become involved if the buyer fails to withhold?
