Using this template.
Grantors and donors often ask for volunteer hours. A consistent log beats reconstructing the year from memory.
This file is one sheet. Columns cover volunteer name, date, activity, hours, supervisor, approval status, and mileage. Approval status is Yes or Pending. It is not a signature page, and there are no extra tabs. Totals are formulas over the log rows, including a blank row above the totals. Insert new rows in that blank row so the formulas keep them. Do not type numbers on the total rows.
Grant and impact reports may value hours. Write the rate source in Notes. Do not record general volunteer time as in-kind revenue. ASC 958-605 recognizes contributed services only when they create or enhance a nonfinancial asset, or require specialized skills the organization would otherwise purchase.
The charitable mileage rate in section 170(i) is 14 cents per mile. That is not the IRS business mileage rate. If you reimburse mileage, use the rate in your policy.
Not every volunteer wants their name on a public report. Aggregate totals may be enough for outside audiences.
