If part of your home is used exclusively and regularly for business, you can deduct a proportional share of rent, utilities, insurance, and repairs. There are two methods: simplified ($5/sqft, max 300 sqft, no depreciation) and actual expense (proportional share of all costs including depreciation).

The actual method produces larger deductions but carries one meaningful risk for homeowners: the depreciation component is subject to 25% recapture tax when you sell the home, even if you exclude the rest of the gain under the primary residence exclusion. The simplified method has zero recapture risk. Your CPA should model both over your expected hold period.

Section 179 allows businesses to deduct the full purchase price of qualifying equipment and software purchased during the tax year. Instead of depreciating over several years, you get the full deduction immediately.

Business vehicle deductions generally use either the optional standard mileage method or the actual-expense method. Purchased vehicles may also qualify for Section 179 or bonus depreciation, subject to business-use, vehicle-classification, and annual passenger-automobile limits.

The IRS changed the 2026 business mileage rate midyear: 72.5 cents per mile applies from January through June and 76 cents per mile applies beginning July 1. Method-selection rules matter, and business use must be supported by contemporaneous mileage records.

An accountable plan lets your business reimburse you tax-free for legitimate business expenses (home office, phone, mileage, meals) that you’d otherwise pay personally with after-tax dollars.

Important: this requires a separate entity paying you as an owner-employee — sole proprietors cannot use an accountable plan (you are the business, so there’s no employer-employee relationship to reimburse). S-Corp owners are the primary beneficiaries. Without proper documentation, reimbursements become taxable W-2 income.

The QBI deduction allows eligible self-employed individuals and small business owners to deduct up to 20% of their qualified business income. This is a significant tax break that phases out at higher income levels.

Filing Status Optimization compares every status legally available to the household, including Married Filing Jointly versus Married Filing Separately and, when the statutory tests are met, Head of Household or Qualifying Surviving Spouse.

Separate filing changes tax brackets, deduction rules, credit eligibility, Roth IRA limits, student-loan calculations, and community-property reporting. Some credits are unavailable or restricted, although limited exceptions can apply to spouses who lived apart. The decision should compare total household tax and non-tax consequences rather than one deduction in isolation.

Strategically timing when you recognize income or take deductions across tax years. Deferring income to a lower-income year or accelerating deductions into a high-income year can reduce your bill — but only by the bracket differential between years, not by eliminating the tax altogether.

Two traps to flag upfront. First, deferring income only helps if your rate next year is equal to or lower than this year — if your business is growing, rates are rising, or you are converting to an S-Corp, deferral can backfire and you end up paying more.

Second, shifting income across quarters without adjusting quarterly estimated tax payments creates underpayment penalties with the IRS — the penalty accrues even if you pay in full at filing. Any meaningful income timing move needs to be paired with a revised estimated payment schedule, not just a deferred invoice.

IRS resolution requires a strategic approach. Penalty abatement removes first-time or reasonable cause penalties, installment agreements spread payments, and voluntary disclosure programs reduce penalties for coming forward proactively.

An Offer in Compromise allows you to settle your tax debt for less than the full amount owed. The IRS considers your ability to pay, income, expenses, and asset equity to determine an acceptable offer amount.

If you missed deductions or credits on previously filed returns, you can file amended returns (Form 1040-X) to recover overpaid taxes for up to 3 prior years.

An S-Corporation election splits your business income into two buckets: a W-2 salary (subject to payroll taxes) and distributions (not subject to self-employment tax). The savings is the SE tax you avoid on the distribution portion.

Note that the figure shown is gross — ongoing payroll administration, state franchise taxes (CA, NY), and your accountant’s additional time are real costs that reduce the net benefit. This also spans two tax filings: a corporate return (Form 1120-S) plus your personal return via Schedule K-1.

Optimizing the balance between W-2 salary and distributions from your S-Corp or C-Corp. Setting the right salary minimizes payroll taxes while staying compliant with IRS "reasonable compensation" rules.

For S-Corp and C-Corp owners, the full compensation picture — salary, distributions, bonuses, fringe benefits, and retirement contributions — must be optimized together. Each dollar moved between these buckets has a different tax cost.

The goal is to minimize total FICA exposure and income tax while keeping your salary in the “reasonable compensation” range required by the IRS. Fringe benefits like employer-paid health insurance, a group term life policy, and an HRA layer on top of the salary/distribution split to reduce taxable income further.

A state pass-through entity tax (PTET) election may allow an eligible partnership or S corporation to pay state income tax at the entity level. IRS Notice 2020-75 generally allows a federal deduction for qualifying entity-level payments, while the owners receive the state-specific credit or income adjustment.

The benefit is no longer a simple comparison with the former $10,000 individual SALT cap. For 2026, the individual SALT limit is $40,400 and phases down at higher modified adjusted gross income, while every state PTET program has its own entity, election, payment, and owner-credit rules.

Self-employed retirement plans like SEP-IRAs and Solo 401(k)s allow much higher contribution limits than traditional IRAs. You can defer significant income while building retirement savings, reducing current taxes substantially.

A defined benefit plan allows dramatically higher annual contributions ($100,000–$300,000+) than a 401(k), sheltering that income from tax today. The savings are a deferral, not an elimination — contributions reduce your taxable income now, but distributions in retirement are taxable as ordinary income.

The net lifetime benefit depends on your current vs. retirement tax bracket. This is a long-term commitment: once established, annual contributions are mandatory regardless of business performance.

HSAs provide a triple tax advantage: tax-deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses. With a high-deductible health plan, HSAs are one of the most tax-efficient savings vehicles available.

The backdoor Roth lets high-income earners contribute to Roth indirectly: make a non-deductible Traditional IRA contribution ($7,500), then convert it to Roth immediately. Done cleanly, the conversion is $0 taxable.

The critical trap is the pro-rata rule: if you have ANY pre-tax IRA money anywhere (old rollovers, deductible contributions from prior years), the IRS treats all IRA assets as one pool and taxes a proportional share of the conversion. One forgotten rollover IRA can make the entire strategy taxable.

The fix is to roll pre-tax IRA balances into your Solo 401(k) first — that sequence is explained in the Solo 401(k) strategy.

A business may deduct reasonable wages paid to a child for legitimate work. For 2026, a dependent’s standard deduction is generally earned income plus $450, capped at $16,100, so wages can produce little or no federal taxable income when the child has no significant other income.

Payroll-tax treatment depends on the child’s age and the employer’s entity type, and state tax may still apply. The deduction depends on reasonable pay, real services, and records that would support the same arrangement with an unrelated employee.

Employing parents or dependents for legitimate business work shifts income out of your tax bracket and into theirs. The strategy works because a parent earning within their standard deduction (~$16,100–$18,250 depending on age) pays $0 federal income tax on those wages.

The savings figure shown is the household net benefit — your income and SE tax savings as the business owner, minus the FICA taxes your parent pays as the employee. Your gross deduction is larger; the net is what the family collectively keeps after all tax obligations are satisfied across both returns.

A compliant Dependent Care Assistance Program can exclude up to $7,500 of qualifying benefits from an employee’s 2026 wages ($3,750 for married filing separately), limited by qualifying expenses and the earned income of the employee and spouse.

Expenses used for the exclusion cannot also be used to calculate the Child and Dependent Care Credit. Plan eligibility, nondiscrimination testing, ownership, filing status, and household facts determine the actual benefit.

The Augusta Rule lets your business pay rent for using your home for legitimate business purposes (meetings, retreats, training) up to 14 days per year. The rent is a deductible business expense on your entity return — and the rental income is excluded from your personal return entirely.

The savings come from two places simultaneously: a deduction on the business side and an income exclusion on your personal side. These are separate line items on separate filings, not a single adjustment.

Strategic charitable giving can include donating appreciated assets (avoiding capital gains), bunching donations in alternating years, using Donor Advised Funds for flexibility, or Charitable Remainder Trusts for larger amounts.

One important gate: charitable deductions only reduce your taxes if your total itemized deductions exceed the standard deduction ($32,200 MFJ / $16,100 single in 2026). If you give $8,000/year to charity but your other itemized deductions are low, you may be taking the standard deduction anyway and getting zero additional tax benefit.

Bunching solves this by concentrating two or more years of giving into one calendar year so you clear the itemization threshold in Year 1, then take the standard deduction in Year 2 — same total dollars given, but only one year of real tax savings instead of zero.

A Donor Advised Fund (DAF) is a charitable account you fund in one year and distribute from over time. You get the full tax deduction the year you contribute — not the year the money reaches the charity. This is the key mechanic: deduction now, distribution later.

Two things to understand before relying on the savings estimate. First, once money enters a DAF it is irrevocable — it legally belongs to the fund sponsor and must eventually go to a qualifying charity. You cannot take it back for personal use.

Second, the deduction only produces real tax savings if you itemize, meaning your total deductions must exceed $32,200 MFJ / $16,100 single in 2026. If you are below that threshold in the contribution year, the DAF contribution does not lower your taxes at all. Bunching — contributing multiple years of planned giving at once — is how most people clear the threshold.

Strategically establishing residency in a state with no or low income tax can save tens of thousands annually. Requires careful planning to avoid dual-residency issues and audit triggers.

For higher-earning business owners, converting to or adding a C-Corp layer can provide access to the flat 21% corporate tax rate on retained earnings, plus additional benefits like expanded fringe benefit deductions not available under pass-through structures.

Cost segregation front-loads depreciation by reclassifying parts of a building into shorter-lived categories (5, 7, or 15 years instead of 27.5 or 39), creating large deductions in year one. The savings are a deferral — you’re pulling future depreciation forward, not creating new deductions.

On sale, the accelerated portion is recaptured and taxed at 25% (IRC §1250). The strategy makes sense when your current tax rate is higher than your expected rate at sale, or when you plan to 1031 exchange and indefinitely defer the recapture.

Real Estate Professional Status changes how the passive-activity rules apply to rental real estate. A qualifying taxpayer must satisfy both statutory time tests, and losses from a rental activity become nonpassive only when the taxpayer also materially participates in that activity (or in an eligible grouped activity).

This can make otherwise suspended rental losses usable against nonpassive income, but status alone does not automatically unlock every rental loss. Contemporaneous time records and activity-by-activity participation are central to the analysis.

A 1031 exchange defers — but does not eliminate — capital gains taxes when you sell investment property and reinvest in like-kind property within strict timelines (45 days to identify, 180 days to close). The gain follows the new property and becomes taxable when it’s eventually sold without another exchange.

The strategy’s value is time: you invest dollars that would have gone to the IRS and let them compound. Chains of 1031 exchanges can defer gain indefinitely; a stepped-up basis at death can eliminate it entirely.

A short-term lodging activity may fall outside the tax definition of a rental activity when average customer use is seven days or less, or under another regulatory exception. The resulting loss is nonpassive only if the taxpayer also satisfies one of the material-participation tests.

The seven-day exception and the 500-hour material-participation test are not the only available tests, and they should not be collapsed into one rule. Guest-stay records and participation logs must support the applicable tests each year.

Tax-loss harvesting sells investments at a loss to offset capital gains and up to $3,000 of ordinary income per year. Unused losses carry forward indefinitely.

The mechanics span multiple years and accounts: when you sell at a loss, your cost basis resets lower, so future gains on a replacement position are larger. The wash sale rule disallows the loss if you (or your spouse, or your IRA) buy a substantially identical security within 30 days before or after the sale — this catches more people than expected because it applies across all accounts, not just the one where the sale happened.

The strategy reduces this year’s tax while shifting some of that tax into future years via the lower basis.

Section 1202 excludes up to $10 million (or 10× your cost basis, whichever is larger) of gain on C-Corporation stock held for 5+ years from federal capital gains tax. At the top rate, that’s up to $2,380,000 in federal tax saved.

The major state-level trap: California does not recognize the exclusion. CA residents owe 13.3% state capital gains tax on the full gain regardless of federal treatment — a $10,000,000 excluded gain still triggers $1,330,000 in CA tax. Founders in CA approaching a liquidity event should explore domicile planning well before the sale.

Trader Tax Status treats qualifying trading activity as a business rather than passive investing. When paired with a timely Section 475(f) mark-to-market election, losses can become ordinary and are not limited to the $3,000 annual capital loss cap.

Direct participation in qualified oil and gas working interests can produce large first-year deductions through intangible drilling costs and depreciation. The tax benefit is tied to a real, high-risk investment, not a stand-alone deduction.

A Qualified Opportunity Fund can defer eligible capital gain and may exclude appreciation on the fund investment after a long holding period. The program remains available, but it is a specialized investment decision rather than a broadly useful tax strategy.

For qualifying investments made beginning in 2027, deferred gain is generally recognized at the earlier of an inclusion event or five years after the investment. A five-year hold generally produces a 10% basis increase, with an enhanced 30% increase for a qualifying rural opportunity fund. A separate fair-market-value basis election may exclude fund appreciation after a 10-year hold.

The benefits must be weighed against fund fees, investment quality, concentration, liquidity, state conformity, and the required holding period. New zone designations begin in 2027, so the applicable zone and fund must be verified before relying on any benefit.

International taxpayers can benefit from Foreign Earned Income Exclusion (up to $126,500), Foreign Tax Credits to avoid double taxation, and treaty benefits. Proper reporting of foreign accounts (FBAR/FATCA) is essential.

If you pay taxes to a foreign government on income also taxed by the U.S., the Foreign Tax Credit prevents double taxation. In some cases, the credit is more valuable than the FEIE.

If you have foreign financial accounts exceeding $10,000 at any point during the year, you must file an FBAR (FinCEN 114). FATCA reporting (Form 8938) has separate thresholds. Penalties for non-compliance are severe.

Cryptocurrency requires careful tax planning. Tax-loss harvesting can offset gains, specific identification of lots optimizes cost basis, and proper reporting avoids IRS penalties. Staking and DeFi have unique tax implications.
