Tax season 2027: a document-request timeline for tax preparers
Returns for the 2026 tax year are mostly prepared between January and April 2027. Preparers who request documents in stages, instead of all at once in March, spend far less time chasing. This is a planning outline; check current IRS and state dates for your clients, and adjust for your practice.
October to November: new and returning client prep
- Confirm which clients are returning and send engagement letters
- Ask clients to flag life changes: moves, marriage, new baby, job change, home purchase or sale, new business
- Collect year-to-date business records from self-employed clients so year-end isn't a scramble
December: year-end planning requests
- Request year-end profit and loss and balance sheet from business clients
- Ask for charitable donation receipts and estimated tax payment records
- Remind clients that W-2s and most 1099s begin to arrive in January
January: send the checklist
- Send each client the document checklist as soon as forms start arriving
- Employer W-2s and many 1099s are due to recipients by January 31; in 2027 the 31st is a Sunday, so confirm the exact date with the IRS
- Set a client deadline well before your own working deadline
February to March: chase only what's missing
- Follow up every few days with only the missing items, not the whole list
- Business entities such as partnerships and S corporations generally file earlier than individuals, so request those documents first; confirm current due dates
- Offer an extension early for clients who won't make the deadline, so it's a plan and not a panic
Early April: final notices
- Send a firm final notice a week or two before the individual filing deadline
- State plainly what the filing deadline and extension options are for that client
- File extensions for clients whose documents are still missing, according to your engagement letter
- Copy-and-paste wording for each stage: /guides/tax-season-client-reminder-email-templates

Frequently asked questions
When should a tax preparer start requesting documents for the 2027 filing season?
Start in October and November with engagement letters and a prompt for clients to flag life changes, ask for year-end records in December, and send the full document checklist in January as forms start arriving.
When are W-2s and 1099s due to recipients?
Employer W-2s and many 1099s are generally due to recipients by January 31. In 2027 the 31st is a Sunday, so confirm the exact date with the IRS.
Which clients should I chase first?
Business entities such as partnerships and S corporations generally file earlier than individuals, so request their documents first. Confirm current due dates for each entity type.
When should I offer an extension?
Early, in February or March, for clients unlikely to make the deadline, so it is a plan rather than a last-minute panic. File extensions according to your engagement letter.
