Catch-Up Bookkeeping in the United States
We turn months (or years) of backlog into clean, tax-ready financials. Delivered to US GAAP for US businesses, priced in USD.
US catch-up work almost always arrives with a date attached — an extension running out, a lender asking for two years of statements, or an acquirer's diligence list. We rebuild period by period and sequence the work backwards from whichever deadline is actually real, rather than working forwards from the oldest gap.
The IRS return dates set the order: 15 March for S-corporations and partnerships, 15 April for C-corporations, with estimated instalments running quarterly underneath. The liability that grows fastest, though, is usually state sales tax — collected and never remitted, or never collected in a state where nexus had already been triggered. We size that before anyone registers anywhere.
The deadlines we track against your ledger.
