Filing is looking backward. 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.
"A family-owned firm with 15 years of experience — we take pride in serving our clients with competence, speed, and accuracy. You'll find our staff to be extremely helpful and a delight to work with."
— 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 is 15.3% on top of income tax. That's not a law — that's a structure problem. We fix the structure and stop the bleed.
Depreciation is the closest thing to a legal tax cheat code. A cost segregation study on a $600K property can generate $80K+ in year-one deductions. We make sure you're using every tool in the code.
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 $180,000 of net income aren't just different structures — they're a $12,000 difference in what you keep. We run the math, model the options, and tell you exactly what your current structure is 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 $70,000+ per year from taxes. A defined benefit plan can shelter even more. Most business owners are using a SEP-IRA and leaving real money behind. Retirement planning isn't just about the future — it's one of the highest-leverage deductions available to you right now.
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.

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.
Whether you're a casual collector, a serious grader, or a full-time dealer — we can help you keep more of your profits.
The IRS distinction between hobby income and business income changes everything. We help you qualify as a business — so your expenses are deductible.
Know exactly what you paid for every card and collection. Proper cost basis tracking is the foundation of minimizing capital gains when you sell.
eBay, TCGPlayer, StockX, and PayPal now issue 1099-Ks at lower thresholds. We help you reconcile these and avoid overpaying.
We ask questions most accountants never ask — about your structure, your income mix, your plans. We're listening for what you're leaving on the table.
We review your returns, your entity structure, and your situation against the full landscape of available strategies. This is where we tell you exactly what's being missed.
We don't just recommend — we implement. Entity elections, payroll setup, accountable plans, cost segregation coordination. We handle the mechanics so you don't have to.
Tax season is when we file. The rest of the year is when we save you money. Quarterly reviews, proactive outreach when the law changes, and a direct line when decisions have tax implications.

Tax law is not static. Congress and the IRS make changes every year — some quietly, some dramatically. Below are the most significant current changes affecting individual taxpayers, families, and business owners right now. Some are in your favor. Some are not. All of them require a strategy.
The Tax Cuts and Jobs Act of 2017 (TCJA) cut tax rates, nearly doubled the standard deduction, expanded the child tax credit, and created the 20% pass-through deduction (Section 199A). Most of these provisions are scheduled to expire after December 31, 2025 — unless Congress acts to extend them.
The IRS dramatically lowered the reporting threshold for Form 1099-K. Previously, payment platforms (PayPal, Venmo, Cash App, eBay, Etsy, StockX, TCGPlayer) only issued 1099-Ks if you received over $20,000 in 200+ transactions. The new threshold is $600 in a single transaction, being phased in — with a $5,000 threshold in 2024, moving toward $600 fully in 2025–2026.
The IRS adjusts the standard deduction annually for inflation. For the 2025 tax year, the amounts are:
The Inflation Reduction Act (IRA) significantly expanded residential and business energy tax credits. These are real dollar-for-dollar reductions in your tax bill — not just deductions.
Bonus depreciation — which allowed businesses to immediately deduct 100% of qualifying asset purchases — has been phasing down year by year since 2023. The schedule is:
Section 179 remains available at $1,220,000 for 2024 and similar for 2025, giving small businesses an alternative immediate expensing route.
The SECURE 2.0 Act (signed into law late 2022, with provisions phasing in through 2025 and beyond) made sweeping changes to retirement savings rules.
Federal taxes are only half the picture. Every state has its own rules, rates, deadlines, and quirks. We serve clients across Hawaii, Utah, Arizona, and California — and we know each state's tax code inside and out.
Hawaii has one of the most complex state tax structures in the nation — with 12 income tax brackets, a General Excise Tax (GET) that functions differently from sales tax in other states, and unique rules for residents who earn income from mainland sources. Understanding the difference between the GET and income tax is critical for any Hawaii business owner.
The General Excise Tax applies to ALL business gross income — not just retail sales. Services, rentals, construction, and even wholesale transactions are subject to GET. Many new business owners get caught off guard because they treat it like a sales tax. It's not — it's a tax on the privilege of doing business in Hawaii, and it must be filed regularly regardless of whether you collected it from customers.
Hawaii's top marginal income tax rate of 11% is the highest in the nation. Combined with federal rates, high earners in Hawaii can face effective rates well above 40%. Strategic use of deductions, retirement accounts, and entity structure is not optional at this level — it's essential. The difference between good planning and no planning can be $10,000+ annually.
Unlike most states, Hawaii's individual income tax deadline is April 20th, giving residents 5 extra days. However, if you also have federal obligations, the federal April 15 deadline still applies. Business returns (Form N-30, N-70NP) have their own schedule. Don't assume Hawaii's later deadline applies to all your filings.
Hawaii offers a 35% state tax credit for solar energy systems installed on residential property — one of the most generous in the nation. Combined with the federal 30% credit, homeowners can offset 65% of installation costs through tax credits. If you're a Hawaii homeowner considering solar, the tax math is compelling and we can help you structure the credit correctly.
Questions about Hawaii GET, N-11 filing, or the solar credit? We file Hawaii returns year-round.
Ask a Hawaii Tax QuestionUtah has a simple, flat income tax structure — making it one of the more predictable states for tax planning. Utah recently reduced its flat rate and is generally business-friendly. However, Utah has unique rules around Social Security taxation, pass-through entity taxes, and a sales tax structure that catches many business owners off guard. Utah also has a strong retirement income tax credit that many residents miss.
Utah allows S-Corps, partnerships, and LLCs to elect to pay state income tax at the entity level. This effectively bypasses the federal $10,000 SALT deduction cap — because the entity deducts the state tax as a business expense before income passes through to you. For Utah business owners paying significant state tax, this election can save thousands annually in federal taxes.
Utah offers a retirement tax credit of up to $450 for individuals and $900 for joint filers who receive qualifying retirement income. This is a credit — not just a deduction — meaning it directly reduces your Utah tax bill. Many retired Utah residents miss this entirely. If you or your spouse receive pension, IRA, or Social Security income, you likely qualify.
Unlike many states, Utah includes Social Security benefits in taxable income — though a retirement credit partially offsets this. Retirees moving to Utah from a state that exempts Social Security (like Hawaii) need to account for this in their planning. The difference can be significant depending on your benefit amount.
Utah is one of a growing number of states expanding sales tax to cover certain services. If you operate a service-based business in Utah, you need to verify whether your specific services are subject to sales tax — the rules are more complex than most people assume and enforcement has increased. An incorrect determination can result in significant back taxes and penalties.
Operating a business in Utah or planning a move there? Let's talk about your Utah tax situation.
Ask a Utah Tax QuestionArizona made a dramatic tax change in 2023 — moving to a flat 2.5% income tax rate, one of the lowest flat rates in the country. This was a major shift from the previous graduated structure and represents a significant opportunity for high earners who moved to Arizona for tax reasons. Arizona also has favorable treatment for retirees and has become a popular destination for California transplants looking to reduce their state tax burden.
As of 2023, Arizona taxes all income at a flat 2.5% — down from a top rate of 4.5% just two years prior. For a household earning $200,000, this change alone saves $4,000 in Arizona state taxes annually. Combined with no tax on Social Security and favorable treatment of retirement income, Arizona has become one of the most tax-efficient states for retirees and high earners in the Southwest.
Like Utah, Arizona allows pass-through entities to elect to pay state tax at the entity level — bypassing the federal SALT cap. For Arizona business owners who are also federal taxpayers subject to the $10,000 SALT limit, this election can convert a non-deductible expense into a fully deductible business cost. The savings can be 2-3x the Arizona state tax paid.
Many California residents move to Arizona to escape California's high taxes — but California aggressively audits high earners who claim to have moved. You must genuinely establish Arizona domicile: driver's license, voter registration, spending more than 183 days in Arizona, and changing professional and social ties. We help California-to-Arizona movers document their residency change correctly from day one.
Arizona's sales tax is called the Transaction Privilege Tax and it works differently from sales tax in most states — it's a tax on the seller's privilege of doing business, not a tax on the buyer. Business owners in Arizona must register, collect, and remit TPT correctly. Contractors, remote sellers, and service businesses often get this wrong, resulting in audits and back taxes.
Recently moved to Arizona or own a business there? We know Arizona's TPT and flat tax inside and out.
Ask an Arizona Tax QuestionCalifornia has the highest state income tax rate in the nation at 13.3% and is one of the most aggressive states when it comes to tax enforcement and auditing. California also has unique rules around residency, source income, and business taxation that can surprise people who move in or out of the state. For business owners and investors, California's treatment of capital gains, stock options, and pass-through income requires careful planning.
Every LLC doing business in California must pay a minimum $800 franchise tax annually — even if the business made no money. New LLCs are exempt in their first year (as of 2021), but from year two onward, the $800 is due regardless of income. LLCs with revenues over $250,000 pay additional fees that can reach $11,790. Many out-of-state LLCs that do business in California are surprised to learn they owe this tax too.
California's PTE tax election (AB 150) allows S-Corps, partnerships, and LLCs to pay a 9.3% entity-level tax — generating a 9.3% California tax credit for each owner. Because the entity deducts this as a business expense federally, it bypasses the SALT cap entirely. For California business owners in high brackets, this can save $5,000–$20,000+ in federal taxes annually. This is one of the highest-value tax strategies available to California business owners right now.
The California Franchise Tax Board (FTB) is one of the most aggressive state tax agencies in the country. When high earners leave California, the FTB may continue to assert that they are still California residents — and can audit up to 4 years back. Triggers include: maintaining a California home, frequent visits, keeping California business ties, or children in California schools. If you've recently left California, proper documentation of your departure is essential.
California has source-based taxation on stock options and RSUs. If you were a California resident when your equity vested or was granted, California may claim a portion of the income even if you've since moved to another state. The allocation formula is complex and often results in unexpected California tax bills for people who moved to Nevada, Texas, or Arizona. This is a major planning issue for anyone with significant equity compensation.
California taxes are among the most complex in the country. Don't navigate them alone.
