Fund returns and K-1s, before your LPs ask.
Rivet works from your administrator's capital accounts and your audited financials. Your LPs get K-1s that reconcile to both.
#1 Most-Rated Firmon Sam's List, YC Deals
Fund tax, without the fire drill.
Waterfalls & allocations
Allocations that follow your LPA, so every capital account matches what each partner would actually receive.
Carried interest
Carry tracked against the three-year holding period, with what your GP members need for their own returns.
Foreign & tax-exempt LPs
Blockers where your LPs need them, and the withholding and reporting that come with foreign partners.
SPVs & co-invest vehicles
Every SPV gets its own 1065 and K-1s, filed on the main fund's timeline instead of months behind it.
QSBS through the fund
QSBS tracked deal by deal, so each partner's K-1 shows the gain they can exclude.
GP & management company
GP and management company returns, with PTET elections where they lower your partners' federal tax.
Everything you need, from one firm.
