Real Estate Tax Calc
The two tests — and why records matter
To qualify as a real estate professional and deduct rental losses as non-passive, you must pass two tests: (1) more than 750 hours per year in real property trades or businesses in which you materially participate, and (2) more than 50% of your total personal service hours are in those activities.
The IRS audits this status regularly and requires contemporaneous records — not a log reconstructed at tax time. The Tax Court has disallowed real estate professional status in many cases where records were created after the fact, contained suspiciously round numbers, or couldn't be corroborated by third-party evidence.
What a good log looks like
A qualifying log shows: date, property address (or description of the activity if not property-specific), activity performed (showings, tenant calls, contractor supervision, leasing negotiations, bookkeeping), and hours worked. Use a calendar, spreadsheet, phone log, or a time-tracking app.
Corroborate the log with objective evidence: email timestamps, text messages with tenants and contractors, mileage records, showing logs from real estate software, receipts for materials purchased. An audit examiner will compare your log against emails with dates and times — consistency is the key.
Grouping election and material participation
If you own multiple properties, making the grouping election lets you treat all rentals as a single activity, combining all hours toward the material participation tests. Without it, you must meet the tests for each property separately — typically requiring 500 hours per property.
The standard is seven tests, the most common being the 500-hour test (500 hours in the activity during the year) or the 100-hour / no-one-else test (100 hours, and no other individual contributes more). Document not just your own hours but also how many hours your spouse, property manager, or other parties worked — the comparison matters for the no-one-else test.
Which activities count — and which don't
Hours that count toward the 750-hour and 50% tests are those spent materially participating in real property trades or businesses: showing units, screening and communicating with tenants, negotiating leases, supervising and performing repairs and maintenance, bookkeeping for the properties, and overseeing contractors. The time must be in a real property trade or business in which you actually work.
Hours that do not count are just as important to know. Purely investor activities — studying financial statements, reviewing operations reports, monitoring finances in a non-managerial capacity — are excluded unless you are involved in day-to-day management. Education and seminars, researching potential acquisitions you do not yet own, and simply being 'on call' without performing work also fail to count. Travel time is scrutinized and is often disallowed when it looks inflated to reach a threshold.
A sample log entry and monthly summary
A defensible daily entry looks like: 'March 14 — 123 Oak St: met plumber for water-heater replacement, 1.5 hrs; drafted and sent lease renewal to tenant, 0.75 hrs; reconciled February rents in spreadsheet, 0.5 hrs.' Each line ties to a date, a property or task, a described activity, and a specific number of hours — not a round 'about 8 hours this week.'
Roll the daily entries into a monthly summary and then an annual total, so you can show both the granular detail and the aggregate that clears 750 hours. Round numbers and identical weekly totals invite suspicion; real work produces uneven, specific hours. The summary should also separate hours by property if you have not made the grouping election, since without it each property must independently meet material participation.
Tools for contemporaneous tracking
'Contemporaneous' means recorded at or near the time of the work — not reconstructed at tax time. Practical tools include a shared calendar with time-blocked entries, a spreadsheet updated weekly, or a time-tracking app that timestamps each entry. The method matters less than the timeliness and corroboration: an examiner will cross-check your log against emails, texts, call logs, mileage, bank records, and contractor invoices that carry their own dates.
Build corroboration into your workflow: email tenants and contractors rather than only calling, keep receipts for materials you buy, and let property-management or showing software generate its own activity logs. When your independent records line up with your hours log, the log becomes credible. When the log is the only evidence and everything else contradicts it, it fails.
What the Tax Court consistently rejects
Across many decisions, the Tax Court has disallowed real estate professional status for recurring reasons, and knowing the patterns helps you avoid them. Logs created after an audit began are given little weight. Estimates and 'ballpark' totals without underlying detail are rejected. Entries with implausible hours — more time on a task than it could reasonably take, or totals that conflict with a full-time W-2 job — are discounted.
The courts also reject hours for investor-type activities dressed up as management, and they weigh your claimed hours against your other commitments. A taxpayer working 2,000+ hours at an unrelated full-time job faces a steep burden showing more than 50% of total service hours were in real estate. The lesson is consistency: your log must be believable in the context of the rest of your life.
Don't confuse the two REP tests with material participation
Qualifying as a real estate professional and deducting a specific property's losses are two separate steps. First, you must pass the entity-level REP tests: more than 750 hours and more than 50% of personal service hours in real property trades or businesses. Passing them removes the automatic 'passive' label from your rentals — but it does not by itself make any given rental non-passive.
Second, you must materially participate in each rental (or in all of them combined, if you make the grouping election), typically under the 500-hour test or the 100-hour/no-one-else test. Your log therefore has to do double duty: prove the aggregate 750/50% thresholds and prove material participation in the specific activities whose losses you deduct. Track both dimensions from the start.
Short-term rentals, spouses, and audit red flags
A related but distinct strategy avoids the REP tests entirely: a short-term rental with an average guest stay of seven days or less is not a 'rental activity' under the Section 469 regulations, so material participation alone — for example, 100 hours with no one else doing more — can make its losses non-passive, with no 750-hour real estate professional status required. The hours log still matters, but for material participation rather than the REP thresholds.
For married couples, remember that the 750-hour test must be met by one spouse individually — you cannot pool spouses' hours to reach 750 — though either spouse's participation counts toward material participation in the activities. Audit red flags to avoid: perfectly round totals, hours that exceed the realistic time a task takes, logs with no corroboration, and totals suspiciously landing just over 750. Aim to clear the thresholds with real, documented margin.
Why the log is worth the effort — the dollars at stake
The reason contemporaneous tracking matters is the size of what it unlocks. Passing the real estate professional tests converts otherwise-suspended passive losses into deductions against your ordinary income — wages, business income, portfolio income. For an investor with significant depreciation, especially after a cost segregation study, that can mean tens of thousands of dollars of losses becoming currently deductible instead of stranded until sale.
Because the payoff is large, the IRS examines the status closely, and the hours log is the pivot on which an audit turns. A credible, corroborated log carries the day; a thin or reconstructed one collapses the whole strategy and can trigger accuracy-related penalties on top of the disallowed losses. Treat the log as you would any record supporting a five-figure deduction: build it in real time, back it with independent evidence, and keep it with the return for the full audit-exposure period. The hour you spend maintaining the log protects the thousands the status is worth.
Frequently asked questions
Can I use a reconstructed log?
The Tax Court has been skeptical of retroactively created logs. Contemporaneous records — created at the time of the work — are required. A reconstructed log may not survive audit.
Do management company hours count toward my 750?
No. The test counts hours you personally participate, not hours others work. Management company hours count against you for the "no one else works more" test.
What if my spouse is the real estate professional, not me?
For a married couple filing jointly, the real estate professional tests must be met by one spouse individually — you cannot combine spouses' hours for the 750-hour test. Each must qualify independently.
Do commuting or travel hours count toward the 750?
Travel time is heavily scrutinized and frequently disallowed, especially when it appears inflated to reach the threshold. Time spent actually performing management or maintenance work counts; time merely driving is questionable and should never be the difference-maker in your total.
Do investor activities like reviewing statements count?
Generally no. Purely investor activities — studying financial reports or monitoring finances without day-to-day management involvement — are excluded from the material participation hours unless you are actively managing the operation.
How long should I keep my hours logs?
Keep them at least as long as the related returns are open to audit — generally three years from filing, longer if losses carry forward or in cases of substantial understatement. Because real estate professional status is often examined years later, retaining the contemporaneous logs and their corroborating records well beyond three years is prudent.
What losses does real estate professional status actually free up?
It converts rental losses from passive — deductible only against passive income — into non-passive losses that can offset wages and other ordinary income. Combined with large depreciation, that can make tens of thousands of dollars of losses currently deductible instead of suspended until sale.
