Tax returns for companies and individuals

Which forms the IRS expects

Your filing set follows your company profile. Typically:

• Single-member LLC, foreign owner: pro forma Form 1120 with Form 5472, plus a personal Form 1040-NR if there is US-connected income.
• Multi-member LLC: Form 1065 and a Schedule K-1 for each member; foreign partners add Forms 8804 and 8805.
• C-Corporation: Form 1120, with the company paying its own tax.
• S-Corporation: Form 1120-S and K-1s. Only US residents can be S-Corp shareholders.
• Single-member LLC, US resident owner: no separate company return; income flows to the personal Form 1040.
• Your exact list is confirmed by a specialist, since the tax year, state and company facts all matter.

Form 5472: the classic non-resident trap

Form 5472 is required for a foreign-owned LLC from its first year, regardless of revenue. It is often missed because owners assume no income means nothing to file. The IRS assesses a penalty for each missing or incomplete form.

If 5472 was not filed for prior years, the exposure keeps building, and the sooner it is fixed, the cheaper it is. Read our guide to Form 5472, or if a penalty has already arrived, how to appeal it.

Plan before December 31

A tax return records what already happened. Many decisions that legally lower your tax have to be made before December 31: how the business is set up, when to make large purchases, how you pay yourself, which expenses you track. By spring they are locked in.

That is why we suggest starting with preparation: a consultation on a specific question or a tax planning strategy session that ends with a step-by-step plan. First we see what can still change, then we file.

What we handle

• mapping the federal forms that match your entity and owner status;
• preparing and filing company returns and the owner's personal return;
• Form 5472 filings and catching up on unfiled prior years;
• quarterly estimated tax payments when tax is due;
• ITIN applications when a return requires one;
• IRS letters and notices, audit support, transcripts and copies of filed returns.

How the process works

• Intro call. 20 minutes, free. We go over your situation and gather questions so the specialist's time goes to your return.
• Profile and documents. We confirm the forms and send a document list: bank statements, P&L, prior returns, ownership and owner payment details.
• Preparation. A specialist prepares the return and reviews it with you.
• Filing and beyond. We file on time, set the next deadlines and, if needed, add bookkeeping.

Received an IRS letter?

IRS and state notices come with strict response deadlines, so they should not sit in a drawer. Send the letter to us: we work out what the IRS wants and, if needed, arrange a call to the IRS with interpretation. We prepare you for the questions they are likely to ask, interpret the conversation and send a written summary with next steps.
