Backup withholding forces payers to deduct 24% from contractor payments after a missing W-9, refused TIN, or CP2100 notice — here is the 15-day and 30-day cure clock, Form 945 deposit rules, and the onboarding setup that keeps small businesses out of the trap.
The 1099-NEC and 1099-MISC reporting threshold rises from $600 to $2,000 for payments made in 2026 under the One Big Beautiful Bill Act. Backup withholding still kicks in at the same threshold, the 1099-K bar resets to $20,000 plus 200 transactions, and most states have not adopted the federal change—so vendor recordkeeping matters more, not less.
Self-employed filers can claim the federal Earned Income Tax Credit on Schedule C net earnings, with a 2025 maximum of $8,046 for families with three or more children. This guide covers eligibility thresholds, how to compute earned income (including the half-SE-tax adjustment), the documentation that survives an audit, and the pitfalls that disqualify otherwise valid claims.
Section 530 of the Revenue Act of 1978 eliminates back federal employment taxes on misclassified contractors when small businesses pass three tests — reporting consistency, substantive consistency, and reasonable basis. Revenue Procedure 2025-10 updated the rules in January 2025, the first major change in 40 years.
Total exposure per misclassified worker now commonly lands between $15,000 and $100,000 once federal back taxes, FLSA back wages with liquidated damages, and state penalties stack. Here is what the 2024 DOL final rule changed, how the IRS and state ABC tests differ, and how Section 530 and the VCSP can cap retroactive liability.
Form W-9 collects your taxpayer ID so payers can issue accurate 1099s. The 2026 OBBBA raised the reporting threshold from $600 to $2,000, and the IRS released a revised form. This guide explains the line-by-line mechanics, the single-member LLC mistake that triggers backup withholding, and the recordkeeping habits that keep January boring.
Form 1099-MISC reports rent, royalties, prizes, and attorney settlements. Under the One Big Beautiful Bill Act, the 2026 reporting threshold jumps from $600 to $2,000. This guide breaks down which box to use, the filing calendar, and the penalty tiers that turn small mistakes into thousands of dollars.
How self-employment tax works in 2026 — the 15.3% combined rate, the $184,500 Social Security wage base, the $400 filing threshold, quarterly estimated payment deadlines, the deductions that reduce both income and SE tax, and the income level where an S-corp election starts to pay off (typically $60K–$80K net).
How rideshare drivers actually owe two federal taxes, why deadhead miles are worth thousands, and the quarterly-payment and 1099-K rules that trip up first-time filers.
Form W-9 collects a contractor's taxpayer ID at onboarding; Form 1099 reports year-end payments to the IRS. The 2026 filing threshold rises from $600 to $2,000 under the OBBBA, and missing a W-9 triggers 24% backup withholding immediately — plus penalties of up to $660 per late form.
