Research and development rarely follow a perfectly predictable timeline.

 

An SBIR/STTR company may encounter delays in prototype development, equipment procurement, laboratory testing, technical validation, or research partner deliverables. Even when meaningful progress has been made, some activities may remain incomplete as the award's original end date approaches.

 

In certain circumstances, a no-cost extension can provide the additional time needed to finish the approved work.

 

But an extension of time does not mean an increase in available funding.

 

For federally funded businesses, that creates an important financial question:

 

Can the company complete its remaining research activities using the funds already authorized under the award?

 

Answering that question requires more than checking the remaining balance in the award budget.

 

The company must examine actual expenditures, outstanding commitments, payroll requirements, indirect costs, vendor invoices, remaining technical work, cash flow, and financial reporting obligations.

 

At Peter Witts CPA PC, we help SBIR/STTR awardees evaluate the accounting and financial considerations behind award extensions so companies can make informed decisions before committing to additional months of performance.

 

What Is a No-Cost Extension for an SBIR/STTR Award?

 

A no-cost extension, often abbreviated as NCE, generally provides additional time to complete the existing scope of a federal award without increasing the federal funding authorized for that work.

 

Depending on the award terms, the extended period may allow the recipient to complete:

• Outstanding research activities

• Prototype development

• Technical testing and validation

• Data analysis

• Research partner deliverables

• Project documentation

• Other approved work that could not be completed within the original schedule

A no-cost extension does not automatically authorize a new scope of work, provide additional money, or eliminate existing financial management requirements.

 

The process also depends on the funding instrument.

 

Federal grants and cooperative agreements may have specific extension authorities and notification procedures. Federal procurement contracts generally require compliance with the contract's modification and authorization provisions.

 

Before continuing work beyond the original expiration date, confirm that the appropriate extension has been authorized.

 

Why Financial Records Matter Before Requesting an Extension

 

The decision to request a no-cost extension often begins with the technical team.

 

Perhaps an experiment needs another month, a subcontractor has fallen behind schedule, or the project requires additional validation.

 

The accounting team must then determine whether the financial plan supports that additional time.

 

An award might show a substantial unexpended balance while the company still has unpaid invoices, outstanding research commitments, or additional payroll costs to absorb.

 

Likewise, a company may have enough authorized funding in total but insufficient operating cash to cover expenses while waiting for federal payments.

 

A financial review should therefore answer three questions:

1. What money remains available?

2. What will it cost to complete the remaining work?

3. Can the company manage the timing of those expenses and payments?

These questions form the foundation of no-cost extension financial readiness.

 

Step 1: Review the Award Terms and Extension Requirements

 

Before preparing financial projections, review the official award documentation.

 

Start with:

• Notice of Award or executed contract

• Original period of performance

• Approved budget

• Statement of work

• Award modifications

• Agency extension procedures

• Prior approval requirements

• Reporting deadlines

• Payment provisions

• Closeout requirements

Determine whether the extension can be initiated under the award's existing terms or requires formal agency approval.

 

NIH No-Cost Extensions

 

For eligible NIH grants, a first no-cost extension of up to 12 months may be available under applicable expanded authorities, provided that no additional funds are required, the approved scope remains unchanged, and the award terms permit it.

 

NIH restored the first-extension functionality in eRA Commons in August 2025. Requests outside the standard first-extension process generally involve the Prior Approval module and NIH review.

 

Recipients should verify their award's eligibility and current submission procedures before taking action.

 

NSF SBIR/STTR No-Cost Extensions

 

NSF's SBIR/STTR guidance requires awardees to submit an extension request with a justification, an estimate of unobligated funds, and a plan for using those funds.

 

Its published guidance specifies submission at least 45 days before the award's expiration date.

 

Importantly, having money remaining is not, by itself, sufficient justification for an extension.

 

NSF also states that awardees cannot authorize their own extensions and should not incur new expenses after expiration while anticipating approval.

 

These differences illustrate why award-specific review matters.

 

Step 2: Prepare an Updated Budget-to-Actual Report

 

The first major financial document to prepare is a current budget-to-actual report.

 

This report should show how much funding was authorized, how much has been spent, and what remains by budget category.

 

Review:

• Direct labor

• Fringe benefits

• Materials and supplies

• Consultants

• Subawards and subcontracts

• Travel

• Equipment

• Other direct costs

• Indirect costs

• Applicable cost-sharing commitments

The report should use the current approved budget, including any authorized modifications.

 

It should also reconcile to the general ledger.

 

A spreadsheet maintained separately from the accounting system may be useful for forecasting, but actual expenditure figures should be supported by accounting records.

 

Example: Remaining Award Budget

 

Consider a hypothetical SBIR Phase II award.

 

Budget Category	Approved Budget	Actual Costs	Remaining
Direct Labor	$250,000	$210,000	$40,000
Fringe Benefits	$65,000	$52,000	$13,000
Materials and Supplies	$90,000	$72,000	$18,000
Consultants	$100,000	$75,000	$25,000
Travel	$15,000	$9,000	$6,000
Indirect Costs	$130,000	$105,000	$25,000
Total	$650,000	$523,000	$127,000

 

Illustrative figures only. These balances do not account for all outstanding commitments or possible award restrictions.

 

The report shows $127,000 in unexpended budget authority.

 

However, this figure does not establish that the full amount is available for additional activities.

 

The company must next determine what portion is already committed.

 

Step 3: Distinguish Remaining Funds From Outstanding Commitments

 

An unexpended budget balance and an unobligated balance are not necessarily the same.

 

The company may have entered into commitments for goods or services that have not yet been recorded as expenditures.

 

Examples include:

• Open purchase orders

• Unpaid consultant invoices

• Outstanding subcontract commitments

• Equipment purchases in progress

• Approved research services not yet invoiced

• Other authorized contractual obligations

These commitments need to be considered when planning the extension.

 

Example: Unexpended Versus Uncommitted Funds

 

Continuing the previous example:

 

Financial Position	Amount
Unexpended budget balance	$127,000
Outstanding consultant commitments	($20,000)
Outstanding equipment commitments	($12,000)
Other committed project costs	($10,000)
Illustrative uncommitted balance	$85,000

 

The company now has a more realistic view of the funding not already allocated to existing commitments.

 

However, the $85,000 still needs to support any additional payroll, indirect costs, and project expenses required during the proposed extension.

 

An extension plan should account for all these obligations without double-counting amounts already included in actual expenditures.

 

Step 4: Identify the Remaining Technical Work

 

The next step is to determine precisely what must be completed.

 

The principal investigator, technical team, project manager, and accounting personnel should review outstanding activities.

 

These may include:

• Incomplete experiments

• Prototype adjustments

• Technical testing

• Data analysis

• Validation studies

• Research partner work

• Outstanding deliverables

• Final documentation

For each activity, identify the expected completion date, responsible personnel, and estimated cost.

 

The resulting work plan should remain consistent with the approved award scope.

 

Connect Technical Progress to Remaining Funds

 

For example, a company might forecast:

 

Remaining Activity	Estimated Cost
Final engineering work	$24,000
Prototype validation	$18,000
Research consultant support	$12,000
Final testing and reporting	$9,000
Total estimated direct costs	$63,000

 

Illustrative costs only. The company must also consider applicable fringe, indirect costs, commitments, and other award requirements.

 

This gives the company a financial basis for evaluating whether the proposed extension is feasible.

 

Without a defined remaining-work plan, additional time can create spending that was not anticipated.

 

Step 5: Review Payroll Timing and Labor Requirements

 

Payroll may be the largest ongoing expense during an extension.

 

Additional months of performance can require continued compensation for engineers, scientists, researchers, technical managers, and founders.

 

Before requesting an extension, determine:

• Which employees will continue working on the award

• What activities they will perform

• How many hours are expected

• What compensation rates apply

• Whether fringe expenses will continue

• When payroll will be processed

• Whether employees will also support other projects

• Whether staffing changes are necessary

The forecast should reflect the work that remains, not merely continue the original monthly payroll budget.

 

Example: Extending Research Labor

 

Suppose an engineer is expected to spend 80 hours completing approved validation activities during the extension.

 

The company's forecast should incorporate the applicable supported labor cost for those hours, together with the appropriate fringe and indirect cost treatment.

 

The company should not automatically budget another full month of the engineer's salary as direct award labor if the employee will also support commercial work or other projects.

 

Actual labor charges must continue to be supported by appropriate timekeeping and labor distribution.

 

Step 6: Review Founder Compensation and Key Personnel Effort

 

Founder compensation deserves additional attention during an extension.

 

A founder may divide time among research, company operations, commercialization, fundraising, and customer development.

 

Before projecting continued compensation, review:

• Approved founder role

• Remaining award-specific responsibilities

• Expected research effort

• Payroll support

• Timekeeping requirements

• Direct and indirect labor classification

• Non-award activities

• Key personnel commitments

• Applicable prior approval conditions

The fact that a founder remains actively involved in the company does not mean all their compensation belongs to the federal award.

 

An extension forecast should reflect the work expected to benefit the approved project.

 

If key personnel effort or responsibilities will change materially, determine whether agency approval or notification is necessary.

 

Step 7: Review Indirect Costs for the Extended Period

 

Indirect costs can materially affect the financial feasibility of an extension.

 

A company may have sufficient direct labor funds remaining but insufficient budget to support the associated fringe, overhead, or G&A costs.

 

Review:

• Applicable indirect rate

• Fringe cost pool

• Overhead cost pool

• G&A cost pool

• Allocation bases

• Remaining indirect cost budget

• Current actual costs

• Expected costs during the extension

• Applicable rate agreements or restrictions

Why Indirect Costs Can Change

 

A company that originally expected to finish research within six months may experience changes in staffing, facilities, administration, and shared resources.

 

These changes can affect indirect cost calculations.

 

For example, continued direct labor may generate additional fringe and overhead costs under the applicable allocation method.

 

The company should evaluate whether its original indirect rate assumptions remain appropriate for the extended period.

 

Rates should not be changed arbitrarily to absorb remaining budget.

 

Any adjustments should follow the applicable agreement, cost principles, and consistent accounting metho dology.

 

Step 8: Review Vendor Invoices and Purchase Orders

 

Outstanding vendor invoices can substantially reduce the funds available during an extension.

 

Before requesting additional time, prepare a list of:

• Open purchase orders

• Unpaid vendor invoices

• Materials not yet received

• Equipment commitments

• Testing services

• Software costs

• Travel reimbursements

• Pending refunds or credits

Confirm the purpose, amount, accounting treatment, and relevant dates of each item.

 

A key issue is whether costs were incurred during the authorized period and whether future purchases will be permitted.

 

An extension does not automatically make previously unallowable costs allowable.

 

Likewise, equipment or materials acquired near the end of an award may require additional scrutiny regarding necessity and benefit to the remaining work.

 

Step 9: Evaluate Consultant and Subaward Commitments

 

Consultants and research partners may also need additional time to complete their responsibilities.

 

Before extending partner activities, review:

• Executed agreements

• Approved budgets

• Remaining scope of work

• Unpaid invoices

• Expected final costs

• Deliverable schedules

• Indirect rate treatment

• Revised completion dates

• Agreement modification requirements

An Award Extension Does Not Automatically Modify Partner Agreements

 

The prime awardee should not assume that an extension of the federal award automatically extends every consultant agreement or subaward.

 

Partner arrangements may need formal amendments reflecting the revised schedule and obligations.

 

These modifications should be coordinated with the approved award terms before additional work begins.

 

The prime awardee should also determine whether the partner's final reporting and closeout responsibilities can be completed within the revised award timeline.

 

Step 10: Investigate Significant Budget Variances

 

Before requesting an extension, investigate where actual costs differ materially from the original budget.

 

Common variances include:

• Higher-than-expected payroll

• Delayed hiring

• Consultant overruns

• Lower material expenditures

• Additional testing

• Equipment procurement delays

• Changes in indirect costs

• Delayed subaward spending

Some variances reflect normal project developments.

 

Others may indicate accounting errors, unsupported costs, or the need for agency approval.

 

The review should determine whether the proposed extension requires rebudgeting or another authorized change.

 

A no-cost extension does not automatically approve changes to the award's budget or scope.

 

The company should confirm its available rebudgeting authority and any prior approval requirements before implementing changes.

 

Step 11: Reconcile Drawdowns and Federal Cash

 

For grant-funded awards, drawdown records should be reviewed alongside the remaining budget.

 

The accounting team should reconcile:

• Federal funds authorized

• Award expenditures

• Drawdowns to date

• PMS or other payment system records

• Bank deposits

• Cash disbursements

• Federal cash on hand

• Outstanding reimbursement requests

• Refunds and credits

These records help determine whether the company has properly managed federal funds during the original performance period.

 

Remaining Award Budget Is Not the Same as Cash Available

 

A company may have $100,000 in unexpended award funding but little federal cash in its bank account.

 

Conversely, a company may have drawn federal funds that have not yet been disbursed.

 

Both situations require appropriate cash management.

 

For applicable federal assistance awards, 2 CFR 200.305 addresses payment timing and the need to minimize the time between receiving and disbursing federal funds.

 

Extending the award does not eliminate those requirements.

 

Step 12: Review Contract Billing and Unbilled Costs

 

For contract-based SBIR/STTR awards, the financial review should also cover contract invoicing.

 

Review:

• Contract funding and ceilings

• Contract line items

• Invoices submitted

• Payments received

• Unbilled costs

• Pending adjustments

• Subcontractor charges

• Indirect cost support

• Billing limitations

• Modification requirements

The appropriate treatment depends on whether the contract is fixed-price, cost-reimbursable, or another contract type.

 

An extension of time does not automatically provide additional contract funding or permit additional costs beyond the contract's authorized terms.

 

For procurement contracts, changes should be coordinated through the appropriate contracting authority.

 

Step 13: Build an Extension-Period Cash Flow Forecast

 

Even if sufficient federal funding remains, the company may need working capital to support continued operations.

 

A cash flow forecast should consider:

• Payroll dates

• Fringe and payroll tax payments

• Consultant payments

• Subaward obligations

• Equipment and materials

• Expected federal drawdowns

• Contract billing dates

• Anticipated federal payments

• Available operating cash

• Other committed business expenditures

This forecast helps identify whether expenses will become due before expected federal payments arrive.

 

For small businesses with limited working capital, payment timing can be as important as the remaining award budget.

 

A company should understand both before extending project commitments.

 

Step 14: Prepare Financial Support for the Extension Request

 

The extension justification should explain why additional time is needed to complete the approved work.

 

The accounting records should show whether the remaining funding can support that plan.

 

An internal support package may include:

• Current award documents

• Approved budget

• Budget-to-actual report

• General ledger detail

• Remaining funds calculation

• Outstanding commitments

• Revised work plan

• Payroll forecast

• Indirect cost forecast

• Consultant and subaward projections

• Cash flow analysis

• Significant budget variance explanations

• Relevant approval documentation

Not every agency requires all these documents as part of the submission.

 

However, preparing them internally provides a more reliable basis for requesting an extension and responding to follow-up questions.

 

Step 15: Understand the Impact on Final Reporting and Closeout

 

A no-cost extension can affect the timing of final financial and technical reports.

 

After an extension is authorized, update the company's reporting calendar.

 

Depending on the award, this may include:

• Federal Financial Reports

• SF-425 reporting

• Final technical reports

• Contract invoices

• Research partner reports

• Equipment and property records

• Invention reporting

• Final indirect cost adjustments

• Award closeout documentation

For federal assistance awards subject to Uniform Guidance, 2 CFR 200.344 generally requires recipients to submit final reports and liquidate financial obligations within 120 calendar days after the conclusion of the period of performance, subject to applicable exceptions and approved extensions.

 

Subrecipient deadlines are generally shorter.

 

The company should verify agency-specific requirements rather than assume that every reporting deadline automatically changes.

 

Continue Financial Reconciliation During the Extension

 

Monthly review should continue throughout the authorized extension.

 

The accounting team should monitor:

• Actual expenditures

• Remaining funding

• Payroll and timekeeping

• Labor distribution

• Indirect costs

• Vendor and partner spending

• Drawdowns or invoices

• Cash flow

• Budget variances

• Documentation

• Closeout preparation

The objective is to reach the revised end date with complete, reconcilable financial records.

 

Common Financial Mistakes When Requesting a No-Cost Extension

 

Several issues can complicate an otherwise legitimate extension request.

 

1. Assuming Remaining Funds Are Uncommitted

 

An unexpended budget balance may already be needed for outstanding invoices, purchase orders, or partner obligations.

 

2. Requesting More Time Without a Revised Cost Forecast

 

The company may know which technical work remains but not how much it will cost to complete.

 

3. Overlooking Payroll and Fringe Costs

 

Additional research months can create labor-related expenses that were not reflected in the original plan.

 

4. Ignoring Indirect Costs

 

Indirect costs may continue to accrue during the extension and reduce remaining funding.

 

5. Failing to Review Consultant Agreements

 

Partner commitments may need amendments to reflect the revised schedule.

 

6. Treating an Extension as Authorization for New Work

 

Additional time does not automatically permit expanded objectives or unrelated expenditures.

 

7. Using Outdated Accounting Reports

 

A remaining-balance calculation is unreliable if the general ledger does not include recent expenditures and corrections.

 

8. Failing to Reconcile Drawdowns

 

Unresolved payment differences can affect financial reporting and closeout.

 

9. Assuming Extension Approval Is Automatic

 

The agency and award instrument determine the necessary authorization.

 

10. Neglecting Final Reporting Deadlines

 

An extension should trigger a review of all relevant financial, technical, and closeout obligations.

Frequently Asked Questions About SBIR/STTR No-Cost Extensions

 

Does a No-Cost Extension Provide More Federal Funding?

 

No. A no-cost extension generally provides additional time without increasing the federal funding already authorized.

 

If additional money is needed, that requires separate consideration under the applicable agency and award procedures.

 

Can an SBIR/STTR Company Request an Extension Simply Because Money Remains?

 

Generally, remaining funds alone are not sufficient justification.

 

The company should demonstrate a legitimate need for more time to complete the approved project.

 

Can Employee Payroll Continue During an Extension?

 

Yes, when compensation relates to authorized work performed during an approved extension period and meets applicable cost, documentation, and award requirements.

 

The company should continue maintaining timekeeping, payroll, and labor distribution support.

 

Can Indirect Costs Continue During a No-Cost Extension?

 

Applicable indirect costs may continue to be incurred and allocated according to the authorized cost structure and award terms.

 

The company should review indirect rate provisions, cost pools, allocation bases, and remaining funding.

 

Can a Company Move Funds Between Budget Categories?

 

Some rebudgeting may be permitted, but an extension does not automatically authorize every budget change.

 

The company should review agency-specific prior approval and rebudgeting requirements.

 

Does an NSF SBIR No-Cost Extension Extend Phase II Proposal Eligibility?

 

No. NSF's published Phase I guidance states that a no-cost extension does not extend the Phase II proposal submission eligibility window.

 

Awardees should also review any separate restrictions involving supplemental funding opportunities.

 

Can a Company Continue Spending While Waiting for Extension Approval?

 

Companies should not assume that expenses incurred after the original award expiration date will become allowable simply because an extension request is pending.

 

Confirm the authorized period and agency requirements before making new commitments or charging additional costs.

 

Does an Extension Delay Award Closeout?

 

An authorized extension generally changes the relevant period of performance end date, which can affect closeout timing.

 

However, interim reporting requirements and other award obligations may continue.

 

The company should update its reporting calendar based on the approved extension and applicable rules.

 

Final Thoughts: More Time Requires a Stronger Financial Plan

 

A no-cost extension can help an SBIR/STTR company complete important research without abandoning approved technical objectives.

 

But the decision should be supported by a clear understanding of the award's financial position.

 

Before requesting additional time, companies should review remaining funds, outstanding commitments, unfinished work, payroll requirements, indirect costs, vendor invoices, partner obligations, cash flow, and reporting deadlines.

 

The goal is not simply to determine whether money appears to remain in the budget.

 

It is to determine whether the remaining authorized resources can support the work required to complete the project.
