What shows up next
First of the month: • List every invoice that's past due. • Send a short, friendly reminder with the invoice number, amount and a payment link. • Anything 60+ days late? Call instead of emailing.
Any site visits this week without a written estimate yet? Send them before the weekend, while the job's still fresh for the customer.
Final 2026 estimated payment (Form 1040-ES). Confirm on irs.gov.
January 31, 2027 falls on a Sunday, so the deadline moves to Monday, February 1, 2027. If you paid a subcontractor $600 or more in 2026, check the IRS's current rules and thresholds.
First 2027 estimated payment (Form 1040-ES), due the same day as the 2026 tax return. Confirm on irs.gov.
Second 2027 estimated payment (Form 1040-ES). Confirm on irs.gov.
Third 2027 estimated payment (Form 1040-ES). Confirm on irs.gov.
Self-employed tradespeople and service pros usually pay federal income tax in quarterly estimates. This calendar lists the 2027 due dates, adjusted where the usual date falls on a weekend or holiday, plus the February 1, 2027 deadline for sending 1099-NEC forms for 2026.
It also builds two money habits: chasing overdue invoices on the 1st of each month, and sending every estimate from the week before Friday afternoon. Tax dates can change, so always confirm on irs.gov. This isn't tax advice.
