The concept of material participation is crucial in many effective tax strategies. Whether you are running a small business, flipping houses, managing a short-term rental, or launching a new venture, the ability to deduct losses often depends on the amount of time you have spent actively participating in the activity throughout the year.
In most cases, taxpayers must pass one of the seven material participation tests in order to be considered as materially participating. This typically involves working more than 100 hours in a year, with no one else working more hours than you, or working more than 500 hours during the year. If you meet one of these tests, you are considered as materially participating. However, if you do not, the activity is considered as passive, and any losses incurred may be suspended.
To make things clearer, let's take a simple example. Imagine Tom and Dick both start new businesses in 2025 and both generate a $100,000 loss. Tom materially participates in his business, so he can most likely deduct the loss. On the other hand, Dick does not materially participate, so his loss is likely to be suspended under the passive activity rules. This is not surprising, but hidden within this area of the law is a question that many professionals often get wrong: When do you begin counting hours towards material participation?
Let's go through the wrong answer, the correct answer, and the part of the Treasury Regulations that many practitioners often fail to quote. The wrong answer is: "You start counting when the business starts." This is the common belief, and it seems reasonable. For instance, for a rental property, you would start counting hours when the property is put into service. For a restaurant, you would start counting when the doors are opened. For a consulting firm that you purchased, you would start counting when you take over operations. Even the IRS auditors, many CPAs, and tax attorneys agree with this answer. However, if you look closely at the regulations, you will realize that this is not what they say. In fact, this answer often leads taxpayers to wrongly assume that they cannot materially participate in the first year of operation, when in reality, they can.
So, what do the regulations actually say? According to Treas. Reg. §1.469-4, any activity that counts towards material participation is defined in three categories. The first one is the conduct of the trade or business, which is the most obvious one. This includes the hours you work after the business is up and running, such as tenant communication in a rental activity, hosting guests in a short-term rental, serving customers in a restaurant, or producing goods or services in an operating business. There is nothing controversial about this category.
The second category is work performed in anticipation of the activity beginning. This is the critical and widely misunderstood part. The regulation explicitly states that activities conducted in anticipation of the commencement of a trade or business also count. In simple terms, this means that pre-launch work counts towards material participation. This includes hours spent on market research, property searches, drafting a business plan, negotiating leases, meeting with lenders, designing a service offering, sourcing suppliers, setting up software and systems, and preparing for launch. As long as these activities occur in the same taxable year as the business's commencement, they count towards material participation. This is particularly important for taxpayers who are launching new ventures or buying real estate.
The third category is research and experimental activities under Section 174. If your business involves software development, product research, formulation work, feasibility studies, or experimentation, the hours spent on these activities also count towards material participation. This can be significant for tech startups or any venture where the R&D phase consumes most of the first year.
Now, you may wonder if these rules also apply to rental activities. The answer is yes. Although the regulations define rental activities separately, Treas. Reg. §1.469-4 simply cross-references the rental activity definition and does not exclude it from the rule that allows for pre-operation, anticipation, and research or planning hours. So, if you start a short-term rental business and spend 200 hours in the spring touring properties, running revenue projections, negotiating with sellers, and learning short-term rental software, and then place the property into service later that year, those 200 hours count towards material participation. This can easily push a taxpayer over the 100-hour or even 500-hour thresholds.
This is especially relevant for first-year loss situations. Many businesses, including rentals, often generate significant startup costs, depreciation, and operating losses in their first year. Taxpayers, and sometimes even their preparers, often assume that since the business did not start operating until later in the year, they only have a few hours of participation. However, this is usually not the case. If substantial time was spent preparing the business earlier in the year, those hours often count towards material participation.
To put this into perspective, let's consider a practical example with a short-term rental. Say Sarah decides to start a short-term rental business in January. She spends 120 hours researching markets, 80 hours touring properties, 40 hours negotiating financing, and 60 hours setting up software, planning the décor, and onboarding cleaners. She closes on a property in August and begins renting it in September. Throughout the rental period, she spends another 60 hours in operations. Sarah's total hours for the year would be 120 + 80 + 40 + 60 + 60 = 360 hours. This easily exceeds the 100-hour test and often the 500-hour test, depending on further operating activity. However, many preparers would mistakenly tell her that she only has around 60 hours of participation.
To make this work in practice, taxpayers must keep contemporaneous records and avoid the "throw-out" categories, which are excluded by Reg. §1.469-5T. These categories include purely investor activities, hours not typically performed by owners, and capital acquisition work for someone who will not operate the business. While these categories rarely apply to someone who personally operates a short-term rental or a small business, they do matter for passive investors.
The big takeaway here is that according to the regulations, material participation does not start when the business starts, but when you start working on the business, as long as it is in anticipation of beginning the activity. This means that for many taxpayers, more hours count towards material participation than they initially thought, and it also means that first-year losses are more deductible than they had assumed, provided they meet one of the material participation tests. For short-term rental operators, in particular, the hours spent on searching, analyzing, acquiring, furnishing, and preparing a property often make up the majority of total participation hours. This is good news, as long as you keep good records.
In conclusion, keeping track of your hours and activities in a timely manner is crucial in order to maximize your deductions and avoid any misunderstandings or mistakes. This rule is especially relevant for first-year businesses that often incur significant startup costs and losses. By understanding the regulations and properly recording your participation hours, you can ensure that you are deducting the appropriate amount and taking full advantage of any available tax benefits.
