Arizona rental property owners must comply with Arizona Department of Revenue (ADOR) requirements including: (1) Arizona individual income tax return (Form 140) reporting rental income and expenses; (2) TPT license and returns for short-term rentals and commercial rentals; (3) annual property tax compliance (administered by county assessors, not ADOR); and (4) withholding requirements if you have employees or contractors. For out-of-state investors with Arizona rental properties, a nonresident Arizona return (Form 140NR) is required. KDA’s Tucson team handles all ADOR filings for rental property owners.

The $25,000 passive loss allowance provides meaningful relief for lower-income rental property owners, but it’s largely irrelevant for high-income Tucson investors. If your AGI exceeds $150,000, the allowance is completely phased out. For investors above this threshold, the strategies that matter are: (1) STR loophole for short-term rental losses; (2) REPS election for full-time real estate professionals; or (3) accumulating passive losses to offset future passive income or release upon property sale. KDA’s team will map your specific passive loss situation.

The IRS scrutinizes STR loophole claims closely, so documentation is critical. You need a contemporaneous time log — kept in real time, not reconstructed after the fact — recording every hour spent on your rental: guest communication, cleaning coordination, maintenance, bookkeeping, marketing, and property management. For the 100-hour test (the most accessible), you need to document that you spent at least 100 hours AND more hours than any other person (including your property manager). KDA’s Tucson team will set up your documentation system and review it quarterly.

Arizona is one of the top 5 states in the country for real estate investors from a tax perspective. The combination of a 2.5% flat income tax (vs. California’s 13.3%), no estate tax, no inheritance tax, Qualified Opportunity Zones in high-growth markets like Tucson, and a business-friendly regulatory environment makes Arizona exceptionally attractive. Add in Tucson’s strong population growth, job market, and real estate appreciation, and the investment case is compelling. KDA’s Tucson real estate CPA team will quantify your after-tax returns and compare them to other states.

The most commonly missed deductions for Tucson real estate investors include: (1) home office deduction for managing your portfolio; (2) vehicle mileage for property visits, contractor meetings, and supply runs; (3) education expenses — real estate courses, books, and conferences; (4) professional development and subscriptions; (5) travel to inspect out-of-state properties; (6) cost segregation on properties owned for years (look-back studies); (7) repair vs. improvement elections under the safe harbor rules; and (8) depreciation on personal property used in rentals. KDA’s Tucson team conducts a full deduction audit for every new client.

A 1031 exchange (named after IRC Section 1031) allows real estate investors to sell an investment property and defer all capital gains taxes and depreciation recapture by reinvesting the proceeds into a like-kind replacement property. There is no limit on how many times you can exchange, meaning you can defer taxes indefinitely and build wealth on a pre-tax basis. KDA’s Tucson real estate CPA team plans 1031 exchanges from the moment you acquire a property — not just when you’re ready to sell — to ensure you maximize the tax deferral.

For Tucson real estate investors, the tax treatment of transaction costs depends on timing. Buying costs (agent commissions, title insurance, attorney fees, inspection fees) increase your basis — they reduce your gain when you eventually sell. Selling costs (agent commissions, closing costs, transfer taxes) reduce your amount realized — they directly reduce your taxable gain in the year of sale. Annual property management fees are currently deductible as rental expenses. KDA’s team will ensure every transaction cost is properly captured and applied to minimize your tax liability.

The repair vs. improvement distinction is one of the most important — and most audited — areas of real estate tax law. Repairs are deductible in the current year (replacing a broken window, fixing a leaky faucet). Improvements must be capitalized and depreciated over 27.5 or 39 years (adding a new bathroom, replacing the entire roof). The IRS uses a ‘betterment, restoration, or adaptation’ test to distinguish the two. Misclassifying improvements as repairs is a common audit trigger. KDA’s Tucson team applies the three safe harbors (De Minimis, Routine Maintenance, Small Taxpayer) to maximize current-year deductions legally.

A Delaware Statutory Trust (DST) is a passive real estate investment vehicle that qualifies as like-kind property for 1031 exchange purposes. DSTs allow investors to exchange out of an active rental property and into a fractional interest in a large institutional property (apartment complex, industrial facility, net-lease retail) without active management responsibilities. The key benefits: (1) no management headaches; (2) access to institutional-quality properties; (3) qualifies for 1031 exchange; (4) minimum investments typically $100,000–$250,000. The drawback: no control over the property and limited liquidity. KDA’s Tucson team will evaluate whether a DST is the right 1031 exchange replacement property for your situation.

House hacking — living in one unit of a multi-unit property and renting the others — is a popular strategy for Tucson real estate investors. The tax treatment: you allocate income and expenses between personal use (your unit) and rental use (tenant units) based on square footage or unit count. The rental portion generates full deductions including depreciation. When you sell, the rental portion is subject to capital gains and depreciation recapture; the personal portion may qualify for the Section 121 exclusion. KDA’s team will optimize your house hacking tax strategy.
