THE LETTUCE ADVANTAGE
What's Included in Your Business Filing
Form 1120-S, Prepared and Filed
The S Corp return is prepared from your tracked activity and filed on your behalf once you sign off.
Schedule K-1
Your K-1 is prepared alongside the return, reporting your share of business income for your personal filing.
W-2 Generation
Available by January 31, generated from the payroll Lettuce has been running all year.
1099-NEC Filing
Paid contractors? Lettuce helps prepare and file 1099s. A 1099-NEC is generally required when you pay $600 or more to a non-employee for services.
Federal and State Returns
All required federal and state business filings are included, not billed separately.
Nothing Re-Entered
The categorized transactions behind the return are the same ones you've been watching all year. The return is a summary of work already done.
FROM TRUEUP TO FILED
Four Steps to a Filed Return
1. Final Payroll by December 20
The last payroll of the year runs by December 20 so your W-2 reflects a complete year.
2. Complete Your TrueUp
Review and confirm your income, expenses, deductions, retirement contributions, and healthcare premiums. Enter anything that happened off-platform or before you joined Lettuce.
3. Review Your 1120-S in February
A preview of the return is available in early February. Nothing is filed until you've seen it and signed.
4. Lettuce Files
Filing is typically completed before the end of February. If you need an extension, the deadline moves to September 15.
Guaranteed Savings, or Your Money Back
