Form 720‑CS (Carrier Summary Report) instructions support motor fuel carriers in filing accurate summaries of all transport activity as part of federal excise fuel tax compliance. This form works in tandem with Form 720‑TO, which reports individual fuel transactions.
Key elements covered in the Form 720‑CS instructions include:
- Reporting obligation: Required from all pipeline operators, vessel operators, and truck carriers who are registered or required to register under IRS fuel excise tax regulations.
- Filing frequency: Generally filed quarterly (due last day of the month following the end of the quarter). Late filing may incur penalties.
- Summary content: Total monthly fuel transport volumes for each shipper across all states or terminals.
- Form 720‑TO link: Ensure each transaction listed on 720‑TO can be traced to the monthly totals summarized on 720‑CS.
To complete the form accurately, follow these tips:
- Standardize location codes: Use IRS‑approved terminal codes and location abbreviations for consistent reporting.
- Match records: Your 720‑CS must align with 720‑TO filings for the same period—IRS audits often compare the two.
- Maintain audit logs: Carriers should keep electronic or physical dispatch logs, shipping documentation, and shipper contracts to support filings.
