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 do I properly set up Form 940 filing for a new employer to ensure FUTA tax compliance?
To set up Form 940 filing for a new employer, first obtain an EIN and determine if the business meets the FUTA tax liability threshold, which for 2026 is $1,500 in wages in any calendar quarter or if the employer had at least one employee for some part of a day in each of 20 or more different weeks during the current or preceding calendar year. Employers must accumulate all wages subject to FUTA tax and calculate the tax at 6.0% on the first $7,000 of wages per employee. After applying any applicable state unemployment tax credits (up to 5.4%), the net FUTA tax rate can be as low as 0.6%. Employers must file Form 940 annually by January 31 following the calendar year in which wages were paid, unless deposits are required, in which case earlier deadlines apply. Establishing a payroll system that tracks FUTA wages separately and aligns with IRS instructions is critical to avoid underpayment penalties.
What steps should be taken to correct an underpayment of FUTA tax identified before filing Form 940?
If an underpayment of FUTA tax is identified prior to filing Form 940, the employer should first recalculate the correct FUTA liability including any adjustments for state unemployment tax credits. The employer should then deposit the additional FUTA tax amount as soon as possible to minimize penalties and interest, using the Electronic Federal Tax Payment System (EFTPS) or other IRS-approved methods. On Form 940, report the corrected FUTA tax liability and include an explanation of the adjustment in the designated section or as an attachment if the underpayment is significant. Timely communication with the IRS and accurate record-keeping of corrected amounts are essential to avoid further compliance risks.
What documentation should be maintained to support FUTA tax calculations and reduce audit risk?
Employers should maintain detailed payroll records documenting each employee's wages subject to FUTA tax, including dates of payment and amounts, for at least four years as required under §6001. Documentation must also include state unemployment tax payments and credits claimed, as these directly affect the net FUTA tax rate. Additionally, records of any exemptions, such as wages paid to certain family members or agricultural laborers excluded under §3306(c), should be preserved. Retaining copies of filed Forms 940, payroll tax deposit receipts, and correspondence with the IRS further mitigates audit risk by providing a clear audit trail demonstrating compliance.
What triggers an IRS audit specifically related to Form 940 and FUTA tax reporting?
IRS audits related to Form 940 are often triggered by discrepancies between reported FUTA tax liability and payroll tax deposits made during the year, inconsistencies with state unemployment tax filings, or unusually low FUTA tax payments relative to payroll size. Significant adjustments or corrections made after initial filing, failure to pay FUTA tax timely, or repeated late filings can also raise red flags. Additionally, employers who consistently claim maximum state credit reduction without corresponding state tax payments may face increased scrutiny. The IRS uses automated systems to cross-check Form 940 data against Forms 941 and state filings, so accuracy and consistency across these documents are paramount.
How does the FUTA tax liability compare for a corporation versus a sole proprietorship with employees?
Both corporations and sole proprietorships with employees are subject to FUTA tax on the first $7,000 of wages paid per employee, taxed at a base rate of 6.0% before credits. However, the classification of wages can differ; for example, sole proprietors do not pay FUTA tax on their own earnings, whereas corporate officers receiving wages are subject to FUTA tax. Additionally, corporations may have more structured payroll systems that facilitate accurate FUTA calculations, while sole proprietors must ensure proper classification and documentation of wages paid to family members or other workers exempt under §3306(c). The net FUTA tax rate after state credits remains the same regardless of entity type, but compliance nuances vary based on business structure.
Can an employer combine wages subject to FUTA tax with those subject to Social Security and Medicare taxes when filing Form 940?
Employers must separately track wages for FUTA tax purposes versus FICA taxes, as the taxable wage bases differ significantly. FUTA tax applies only to the first $7,000 paid to each employee annually, whereas Social Security taxes apply up to $184,500 in 2026 wages, and Medicare taxes apply without a wage base limit. While wages subject to FUTA are also generally subject to FICA taxes, the employer must ensure that only the appropriate wages are reported on Form 940 to avoid overpayment or underpayment. Form 940 instructions explicitly require calculating FUTA wages independently, and combining wage amounts can lead to reporting errors and potential penalties.
What key points should I communicate to a client about their Form 940 filing obligations and FUTA tax risks?
When advising clients, emphasize that FUTA tax is an annual federal payroll tax that funds state unemployment programs and must be accurately reported on Form 940 by January 31 of the following year. Explain that only the first $7,000 of each employee's wages are subject to FUTA at a base rate of 6.0%, reduced by state credit up to 5.4%, and that failure to comply can result in penalties and interest. Highlight the importance of consistent payroll records, timely deposits if required, and understanding when state credits may be reduced due to late state unemployment tax payments. Finally, advise clients that underreporting wages or misclassifying workers can trigger IRS audits and costly adjustments.
