Federal safe harbor $11,800 per payment

Some 2026 deadlines have already passed. A quarter of that total was due by each one, so a quarter paid late can still carry a penalty; paying now stops it growing. See what it costs.

Pay at least $1,978 across the year, on the North Carolina installment dates, and the North Carolina underpayment charge cannot apply. Based on 90% of this year's estimated North Carolina tax. Add last year's North Carolina tax below to see if that test is cheaper.
