We provide comprehensive online US tax filing services including Form 5472 filing, 1040-NR tax returns, Schedule C tax filing, and US corporation tax returns. Our team specializes in foreign-owned LLC tax compliance and small business bookkeeping services across the USA. If you own a US LLC as a non-resident, the IRS requires you to file Form 5472 along with a pro-forma 1120 return. Failure to comply can result in a $25,000 IRS penalty per year. We manage the entire foreign-owned LLC compliance process — including EIN assistance, annual reporting, tax filing, and ongoing bookkeeping — ensuring your business remains fully IRS compliant and penalty-free.
