Material Participation Template

Your hours only count if you wrote them down.

Built for hosted Bitcoin mining. Twenty activity categories drawn from a CPA memo, a dashboard that tracks you against the 100 and 500 hour tests, and enough structure that a year of entries reads like a record instead of a reconstruction.

On compliance

The burden of substantiating participation hours sits with the taxpayer, not with the hosting provider or the pool. A dated log kept as the work happens is how that burden gets met, and it has to exist before anyone asks to see it. This template gives you the format. Your tax advisor decides how your facts apply.

What the log is for

Hours are the evidence. The log is where the evidence lives.

Whether a mining activity is treated as nonpassive turns on a facts and circumstances test. These are the pieces your advisor will be working from.

§1.469-5T(a)(3)

More than 100 hours

One safe harbor is met at more than 100 hours in the year, provided no other individual participates more hours than you. That second condition matters in a hosted arrangement, so the log asks you to note who else was involved.

§1.469-5T(a)(1)

Or more than 500

A separate test is met at more than 500 hours, with no comparison to anyone else. The dashboard tracks you against both, so you and your advisor can see which one your year actually supports.

§1.469-5T(f)(2)(ii)

Reading a report is not enough

Work done in the capacity of an investor does not count unless you are directly involved in day to day management or operations. Five of the twenty categories carry a flag so you know to document the decision, not just the review.

Groetzinger, 480 U.S. 23

Continuity and regularity

A trade or business requires continuity, regularity, and a profit motive. Dated entries spread across twelve months show that pattern. A block of hours logged the week before filing does not.

Precedent

What the Tax Court has accepted as proof.

Three cases summarized inside the workbook. Read together, they say something useful: hours worked at a distance can count, and the record you kept is what decides it.

Barbara v. CommissionerRemote work counts

An owner ran a lending business from Chicago while spending 60% of his time in Florida. Daily calls to the office, plus contact by phone, fax, and email, counted toward material participation.

Tolin v. CommissionerCorroboration carries it

A horse breeding activity run largely by long distance calls to the boarding facility and breeders. The court accepted remote calls, promotional work, and travel, and leaned on phone bills, narrative summaries, and testimony to back the hours claimed.

Padda v. CommissionerDetail beats assertion

Restaurant and brewery activities where detailed testimony on involvement in every part of the business carried the day. The work was not dismissed as investor type because it went past reviewing reports and non-managerial monitoring.

Start logging this month, not next April.

Contemporaneous entries are worth more than anything assembled later. Download the workbook, set your tax year, and put in your first row today.
