R&D Credit Forms and Filing
The agent drafts the forms. A licensed CPA or enrolled agent reviews them. An authorized provider files them. Here is what each form is for and how the pieces fit together.
How forms fit into a claim
The paperwork for a research credit claim is the last link in a long chain. Evidence, costs and calculations come first, and forms are where those results are reported to the tax authorities. That is why this site spends more time on how the evidence is gathered than on the forms themselves. Still, the forms matter, and it helps to know what each is for, who completes it and how the agent supports the work.
The federal credit is claimed on a main form, with a separate form used by some small businesses to apply part of the credit against payroll tax, and other forms for general business credits and amended returns. Many states have their own credits with their own forms and rules. The pages below describe each, in general terms, and link to official sources where you can check the current details.
What the agent prepares
The agent drafts. It does not file or sign.
- A draft of the main federal form, with figures tied to the costs and business components captured during the year.
- Supporting schedules and a claim pack that links each number back to its evidence.
- Drafts of state forms where supported, for the reviewer to check against current state rules.
- Information the reviewer needs to prepare an amended return when a claim is made for an earlier year.

A worked example (illustrative)
This scenario is invented. A reviewer opens the draft of the main federal form for a client and sees that the qualified wage figure is linked to a schedule showing each engineer's time on each project. She follows one line back to a payroll record and the time allocation behind it, finds that a manager had adjusted a split for a part-time contractor with a short reason, and accepts it. A second figure links to a project with a thin record. She marks it for follow-up and asks the client for a clearer note. The form is not finished until she is satisfied, and the agent shows exactly what she changed.
Limits and cautions
Forms and instructions change, and states differ. The pages here are general descriptions with links to sources, and they carry no promise that they are current. They are not tax advice. The agent drafts forms, but a licensed CPA or enrolled agent must review them, and an authorized provider must file them. We do not claim that using the agent will result in a credit being accepted.
Forms are filed through an authorized IRS e-file provider or tax software, not by Cost Guru directly.
A checklist for the reviewer before anything is filed
A reviewer can use this list to organize a final read-through.
- Each business component is described, and the description says what was uncertain.
- Evidence is dated and tied to the right project.
- Time allocations follow from records or have a recorded reason.
- Wages, supplies and contractor costs trace to source records.
- The calculation method has been chosen by the CPA or enrolled agent, and figures follow from it.
- State forms have been checked against the state's current rules.
- The narrative, schedules and forms agree with each other.
- The professional who signs has read the claim pack, not only the forms.
Reading the official sources
Each form page links to official pages where you can read current instructions. Please use them. Our descriptions are written in plain language to give you the idea, and they cannot replace the instructions, which are the authority. When instructions change, the form pages here may lag behind, so treat a date on an official page as more reliable than anything you read on a summary. If a source and this site disagree, believe the source and tell us.
Official sources are often long. A practical approach is to read the instructions for the form with a specific claim in front of you, so each paragraph has something to attach to.
Start early
Preparing forms is quick when the evidence and costs are already in order and slow when they are not. If you plan to claim, begin gathering records long before filing, and talk to your CPA or enrolled agent about timing, including any deadlines that apply to amended returns or to elections. We cannot tell you the dates that apply to you, and we recommend checking them with a professional.
Forms questions
Does Cost Guru file my return?

Does it cover every state?
No. Coverage is limited, and states are described briefly on their own pages with links to official sources.
Can it prepare an amended return?
It can help assemble the information a reviewer needs for an earlier year, subject to the records available. The reviewer prepares and files the amended return.

The responsible professional, as the rules for the return require. The agent does not sign.
Where can I check current rules?
On the official tax authority pages linked from each form page, and with your CPA or enrolled agent.
