Look for a CPA license (Certified Public Accountant) or EA designation (Enrolled Agent), combined with demonstrated specialization in real estate tax. Ask how many of their clients are real estate investors, whether they own investment properties themselves, and whether they can explain cost segregation, REPS, and 1031 exchanges fluently. KDA’s Tucson team checks every box — licensed, specialized, and deeply experienced in real estate tax strategy.

Installment sales make the most sense when: (1) you can’t find a suitable 1031 replacement property; (2) you want to generate passive income from the sale proceeds; (3) spreading the gain over multiple years keeps you in lower tax brackets; or (4) you’re approaching retirement and want to match income recognition with your lower-income years. KDA’s Tucson real estate CPA team has structured installment sales for dozens of investors and will show you exactly how the tax math works for your specific property.

The at-risk rules are a threshold test that must be passed before the passive activity rules even apply. For Tucson real estate investors, the good news is that qualified nonrecourse financing — the standard mortgage from a bank or commercial lender — counts as at-risk. This means your deductible losses include not just your equity but also your mortgage balance. The at-risk rules become relevant when you use seller financing, related-party loans, or other non-qualified financing. KDA’s team will analyze your financing structure and confirm your at-risk amount.

Beyond the 2.5% flat income tax, Arizona offers real estate investors: (1) no state estate or inheritance tax — your heirs keep more; (2) Opportunity Zone investments in designated Tucson areas for additional capital gains deferral; (3) relatively low property tax rates compared to national averages; (4) no tax on long-term residential rental income at the state TPT level; and (5) a business-friendly regulatory environment that makes operating rental properties simpler than in many other states. KDA’s Tucson team will ensure you’re capturing every Arizona-specific tax advantage.

The passive activity rules are the primary obstacle for real estate investors trying to use rental losses to offset their W-2 income. Under Section 469, rental losses are passive and can only offset passive income — unless you qualify for REPS or the STR loophole. Suspended passive losses accumulate and are released when you sell the property or generate passive income. For Tucson investors with large suspended passive losses, a strategic sale or the right property acquisition can unlock years of accumulated deductions. KDA’s team will model your passive loss position.

Real estate is one of the most estate-tax-efficient assets to hold and transfer. The key strategies: (1) Stepped-up basis at death — heirs receive your property at its fair market value on your death date, eliminating all accumulated capital gains and depreciation recapture; (2) 1031 exchange + hold until death — defer all gains through 1031 exchanges, then die holding the property for a complete tax elimination; (3) Irrevocable trusts — remove appreciating real estate from your taxable estate while maintaining some control; (4) Family limited partnerships — transfer real estate to children at a valuation discount. KDA’s Tucson team works with estate planning attorneys to integrate real estate into your estate plan.

Arizona’s property tax system differs significantly from California’s in one key way: there is no Prop 13-equivalent cap on annual assessment increases. Your Tucson rental property can be reassessed at full market value each year, potentially leading to significant property tax increases in a rising market. The good news: Arizona’s overall property tax rates are moderate, and residential rental properties benefit from a lower assessment ratio (10%) than commercial properties (18%). KDA’s team will track your assessments and identify appeal opportunities.

TPT compliance is a critical but often overlooked obligation for Tucson short-term rental owners. Arizona requires STR operators to register with ADOR and obtain a TPT license. While Airbnb and VRBO remit state-level TPT on your behalf, you may still be responsible for city-level TPT in Tucson and surrounding municipalities. Failure to comply can result in penalties, interest, and back taxes. KDA’s Tucson real estate CPA team handles TPT registration, compliance, and filing for all types of Arizona rental properties.

The STR loophole is the most popular tax strategy among high-income W-2 earners in 2026 for good reason. By purchasing a qualifying STR in Tucson, materially participating in its management, and running a cost segregation study, you can generate large paper losses that offset your salary dollar-for-dollar. A physician earning $500,000 who generates $200,000 in STR losses saves $74,000+ in federal taxes alone. KDA’s team will model your specific income profile and show you exactly how much you can save.

Yes — rental property grouping under Treas. Reg. 1.469-4 allows you to combine multiple rental activities into a single activity for material participation purposes. This is particularly powerful for the STR loophole: if you group your STR with other rental activities, you can meet the material participation test across the grouped activity rather than for each property individually. Grouping elections are made on your tax return and are generally irrevocable — making it critical to get the election right the first time. KDA’s Tucson team will analyze your portfolio and recommend the optimal grouping strategy.
