Planning is looking forward — at what you can still do before the year closes, before the deduction window passes, before the strategy option expires. Most tax preparers never have that conversation. We make it the foundation of everything we do.

— RP Tax Service · Est. Honolulu, HawaiiFifteen years of returns means we've worked through the scenarios — the business owner who waited too long to elect S-Corp, the investor who missed the 1031 deadline, the crypto holder who didn't track cost basis. We help you avoid what we've watched others lose.
You built the business. We structure it so the IRS takes as little of it as possible — entity election, retirement accounts, accountable plans, and timing strategies that work year-round.
Self-employment tax runs 15.3% on top of income tax. For many owners, the right structure (such as an S-Corp election) can reduce the income that's subject to it. We model whether that move makes sense for your numbers.
Depreciation is one of the most powerful tools in the code. On the right property, a cost segregation study can generate substantial year-one deductions — in some cases well into five figures, depending on the property and your tax situation. We make sure you're using every tool available to you.
Marriage, kids, a home sale, an inheritance — every life event has a tax dimension. We're the advisor who knows what to do when it happens, not after.
Every trade is a taxable event. Every 1099-K from eBay or TCGPlayer has a story behind the gross number. We track cost basis, harvest losses, and make sure you pay tax on profit — not on sales.
From idea to incorporated to scaling — the tax decisions you make early define what you keep later. We're the advisor in the room when structure, compensation, and reinvestment strategy actually matter.
Most tax surprises aren't surprises — they're the result of not looking forward. We model your income, review your structure, and identify every legal reduction available before December 31 closes the window. Quarterly check-ins, proactive communication, and a strategy that evolves as your income does.
An LLC taxed as a sole prop and an S-Corp on the same net income can produce very different tax outcomes — in many cases a difference of several thousand dollars a year, depending on your income, payroll, and state. We run the math, model the options, and tell you what your current structure may be costing you.
The financial decisions you make in your first few years compound for decades. Structure, compensation, retirement, reinvestment — these aren't accounting tasks. They're the difference between a business that builds wealth and one that generates income you can't keep.
Real estate investors often have six-figure deductions sitting in their properties that no one has unlocked. Cost segregation, bonus depreciation, the short-term rental exception, 1031 exchanges, real estate professional status — most Schedule E filers use none of these. We use all of them.
Your crypto platform doesn't track your taxes — it tracks your trades. Cost basis, holding period, DeFi income, 1099-K reconciliation — these are your responsibility and the IRS is watching. We've seen clients overpay by tens of thousands because no one built their cost basis correctly from the start.
Bad books don't just create compliance risk — they prevent good tax planning. You can't optimize what you can't see. We build your financials around your tax strategy: the right accounts, the right timing, the right documentation for every deduction you plan to take.
A Solo 401(k) can shelter a significant amount of income each year — up to the IRS annual limits, which can reach the high five figures for those who qualify. A defined benefit plan can allow even more. Many business owners default to a SEP-IRA and leave room on the table. We help you choose the plan that fits your income and goals.
An IRS notice isn't always a disaster — but responding incorrectly turns a manageable situation into an expensive one. As Enrolled Agents, we hold the highest credential the IRS issues to non-attorneys. We speak their language, know the programs, and represent your interests at every level of the agency.
Real strategies used by smart business owners. Actionable insight, not theory.
The right entity isn't about simplicity — it's about math. We break down when the S-Corp election actually makes sense and when it costs more than it saves.
Read the Strategy →Section 280A lets you rent your home to your business for up to 14 days per year — tax-free to you — when there's a legitimate business purpose and rent is set at fair market value. Here's how to document it correctly.
Read the Strategy →A cost segregation study reclassifies building components to depreciate them faster — unlocking major deductions in year one instead of over 39 years.
Read the Strategy →Your exchange's 1099 reports gross proceeds — not profit. Without proper cost basis records, you may be paying tax on revenue instead of gains. Here's how to fix that.
Read the Strategy →An accountable plan lets your S-Corp reimburse you for business expenses paid personally — with no income tax or payroll tax on qualifying reimbursements. When structured and documented correctly, this one tool can recover meaningful amounts each year that were previously lost.
Get This Set Up →Our partner is a serious collector and dealer of trading cards, Pokémon, One Piece, Disney, and other premium collectibles. That means we don't just understand the hobby — we understand the business of collectibles and exactly how the IRS treats it.
Most accountants treat collectibles like any other asset. We treat them like what they are — a passionate market with unique tax rules, platform income, inventory management considerations, and real money on the line.
The IRS distinction changes everything. We help you qualify as a business so your expenses are deductible.
Know exactly what you paid. Proper tracking reduces your capital gains liability down the road.
We ask questions most accountants miss. We're listening for exactly what you're leaving on the table.
We review your returns and structures against the complete landscape of available planning tools.
We implement the mechanics: entity transitions, accountable plan configuration, and timeline tracking.
Tax season is when we file. The rest of the calendar year is when we dynamically protect your cash flows.

S-Corp · Q4 Advisory Session Scheduled
"They uncovered structural deductions my previous accountant completely missed within my entity alignment."
"Converting to an S-Corp on their advice structurally optimized our self-employment tax liabilities beautifully."
"Jacob Siaosi assisted me beautifully. Thorough, patient, and clear."
Hawaii features distinct rules regarding General Excise Tax (GET) compliance and unique filing deadlines that differ from standard federal schedules.
Utah uses a flat income tax rate, making tax planning predictable. The state also offers a pass-through entity tax (PTET) election that can help business owners work around the federal $10,000 SALT cap.
Arizona offers one of the most competitive flat-rate income tax structures in the country. Small businesses should be aware of Transaction Privilege Tax (TPT) obligations, which function similarly to a sales tax but apply to the seller.
California has the highest top marginal income tax rate in the country. Franchise Tax Board (FTB) compliance is strict, and the state applies source-based taxation rules that can affect remote workers and equity compensation. Entity structuring is especially important here.
