A nephrologist in a W-2 practice position adds $50,000 of 1099 telehealth income in 2026 and sets up federal quarterly payments that hit her 110% federal safe harbor exactly. Her state levies a flat 5% income tax and has its own estimated-payment statute. What is true of her state obligation?

Question

Accepted Answer

She likely owes separate state estimated payments — roughly $2,500 here — through her state's own vouchers and deadlines, whose safe harbors and penalty rules may differ from the federal ones

Answer

Her federal estimated payments cover the state liability, because the IRS forwards each state its share

Answer

Her state withholding on W-2 wages automatically scales up to cover the 1099 income

Answer

States may only collect income tax at filing, so no state prepayment can be required
