What is the S-Corp election and how does it reduce self-employment tax?
An S-Corp election allows the owner to split income between a reasonable salary (subject to 15.3% FICA) and distributions (not subject to FICA). For a business owner with $200,000 in net profit paying an $80,000 salary, the annual SE tax savings are approximately $15,500–$18,500. The S-Corp must file
Form 2553 within 75 days of formation.
What is the Section 199A QBI deduction and how does it apply?
The §199A deduction allows pass-through business owners to deduct up to 23% of qualified business income (QBI) from taxable income under OBBBA. For taxpayers above $403,500 (MFJ) in 2026, the deduction is limited to the greater of 50% of W-2 wages or 25% of W-2 wages plus 2.5% of qualified property.
What retirement plan options are available for self-employed professionals?
Self-employed professionals can establish a Solo 401(k) (up to $70,000 in 2026), a SEP-IRA (25% of net self-employment income up to $70,000), a SIMPLE IRA ($16,500 + $3,500 catch-up), or a Defined Benefit Plan (up to $280,000+ depending on age). The Solo 401(k) is the best option for most self-employed professionals.
How does the home office deduction work for self-employed professionals?
Self-employed professionals who use a dedicated home office space exclusively and regularly for business qualify for the home office deduction under §280A. The deduction is calculated as a percentage of home expenses equal to the office square footage divided by total home square footage. The simplified method allows $5/sq ft up to 300 sq ft ($1,500 maximum).
What vehicle deductions are available for self-employed professionals?
Self-employed professionals can deduct vehicle expenses using either the standard mileage rate (70 cents/mile in 2026) or actual expenses. Vehicles with a GVWR over 6,000 lbs qualify for §179 expensing and bonus depreciation without luxury auto limits. A mileage log must be maintained for either method.
What is the Augusta Rule and how can it benefit business owners?
The Augusta Rule (§280A(g)) allows homeowners to rent their primary or secondary residence to their business for up to 14 days per year. The rental income is completely tax-free to the homeowner, and the business deducts the rent as a business expense. At $2,000–$3,000/day for 14 days, this strategy generates $28,000–$42,000 of tax-free income.
How does cost segregation apply to business owners who own real estate?
Cost segregation reclassifies building components into shorter depreciation categories eligible for bonus depreciation. For a $1M commercial property, cost segregation typically identifies $150,000–$250,000 of accelerated depreciation, generating $60,000–$100,000 in first-year deductions at the 100% bonus depreciation (restored by OBBBA for property placed in service after Jan 19, 2025) rate in 2026.
What is the self-employed health insurance deduction?
Self-employed professionals can deduct 100% of health insurance premiums (for themselves, their spouse, and dependents) as an above-the-line deduction under §162(l). This deduction reduces AGI and is available even if the taxpayer does not itemize. S-Corp owners must include premiums in W-2 wages before claiming the deduction.
How should a self-employed professional handle estimated tax payments?
Self-employed professionals must make quarterly estimated tax payments by April 15, June 15, September 15, and January 15. The safe harbor is 100% of prior year tax (110% if prior year AGI exceeded $150,000). Failure to pay sufficient estimated taxes results in an underpayment penalty under §6654.
What is the excess business loss limitation for pass-through owners?
Under §461(l), pass-through business owners cannot deduct business losses exceeding $305,000 (single) or $610,000 (MFJ) in 2026 against non-business income. Excess losses are treated as an NOL carryforward to the following year.
How does the net investment income tax (NIIT) affect self-employed professionals?
The 3.8% NIIT applies to net investment income for taxpayers with MAGI above $200,000 (single) or $250,000 (MFJ). Active business income and wages are not subject to the NIIT. Self-employed professionals who invest in rental properties or passive businesses should plan for the NIIT impact.
How should a tax professional set up the reporting process for Form 8938 for a client with multiple specified foreign financial assets?
To set up reporting for Form 8938, first identify all specified foreign financial assets exceeding the filing threshold based on the client's filing status and residency. For 2026, unmarried taxpayers living in the U.S. must file if the total value exceeds $75,000 on the last day of the tax year or $150,000 at any time during the year. Gather comprehensive documentation such as account statements and ownership records. Implement a tracking system to monitor asset values throughout the year, ensuring timely aggregation and accurate valuation to meet the FATCA requirements under §6038D.
What are the critical compliance risks and audit triggers related to Form 8938 that tax professionals should advise clients about?
Significant audit triggers include failing to file Form 8938 when required, underreporting the value of foreign assets, or inconsistencies between Form 8938 and FBAR filings. The IRS cross-checks these forms to detect non-compliance. Additionally, omitting foreign financial assets that meet the 2026 threshold of $250,000 for married filing jointly can lead to substantial penalties. Tax professionals should emphasize maintaining detailed records and reconciliation between Forms 8938 and
FinCEN Form 114 to mitigate audit risk and comply with §6038D.
What steps must be taken to file Form 8938, and when is it due relative to the client's income tax return?
Form 8938 is filed as an attachment to the client's annual income tax return (
Form 1040 or 1040-SR). The form is due on the same date as the return, including extensions, generally April 15, 2027, for the 2026 tax year. Tax professionals must ensure the form accurately reports aggregate values of specified foreign financial assets as of the end of the tax year and any acquisitions or dispositions during the year. Failure to attach it timely can trigger penalties under §6038D.
What documentation should tax professionals maintain to support Form 8938 disclosures in case of IRS inquiry?
Maintain detailed records of all specified foreign financial assets, including account statements, brokerage confirmations, and ownership documents. Documentation should also include currency conversion records to U.S. dollars using appropriate exchange rates. Retain evidence of the valuation method used and any correspondence with foreign financial institutions. These records support the accuracy of disclosures required under §6038D and are crucial to defend against potential IRS examinations or penalty assessments.
How does reporting on Form 8938 compare and coordinate with the FBAR filing requirements?
While both Form 8938 and FBAR (
FinCEN Form 114) require disclosure of foreign financial assets, they have different thresholds and filing authorities. The FBAR must be filed if aggregate foreign financial accounts exceed $10,000 at any point during the year, with the deadline generally April 15 with an automatic extension to October 15. Form 8938 thresholds are higher and tied to filing status, with reporting to the IRS as part of the income tax return. Tax professionals must coordinate both filings to ensure consistency and completeness, as discrepancies can trigger IRS scrutiny under §6038D and Title 31 regulations.
Can a client who has both foreign financial accounts and foreign financial assets combine their reporting on Form 8938, or are separate disclosures required?
Form 8938 requires reporting of specified foreign financial assets, which can include foreign financial accounts but also encompasses foreign stocks, securities, and interests in foreign entities not reported on FBAR. If the client meets the filing thresholds, all specified assets must be disclosed on Form 8938 regardless of whether they are also reported on FBAR. However, Form 8938 does not replace FBAR filing; both may be required. Therefore, separate disclosures are necessary, but the tax professional must ensure values and information are consistent to avoid discrepancies under §6038D.
What key questions should tax professionals ask clients to accurately determine the need to file Form 8938 and ensure proper reporting?
Professionals should inquire about all foreign financial assets, including bank accounts, stocks, bonds, interests in foreign entities, and foreign-issued life insurance or annuity contracts. They should ask about asset values during the tax year and at year-end to assess whether thresholds for 2026 filing ($50,000 for unmarried taxpayers living abroad, $75,000 for unmarried U.S. residents, and $150,000 for married filing jointly) are met. Clarify whether the client has signature authority or ownership interest in foreign accounts. Also, confirm previous Form 8938 filings to maintain continuity and compliance with §6038D.
