Financial planning for business owners works best as a year round rhythm, not a once a year event. Close out the year in January, file taxes in the spring, refresh your plan in May, check your progress mid-year, and make tax-saving moves and set new goals before December 31. The checklist below walks through each season.


Most business owners only think about their finances when a deadline forces them to. That's how April tax surprises, missed deductions, and cash crunches can happen. Following the calendar can put the right decisions in front of you at the right time.


Key Takeaways


  • Tax deadlines drive much of a business owner's financial calendar, so plan around them.

  • Many tax-planning opportunities require action before December 31, rather than waiting until tax-filing season.

  • Florida businesses may have additional state deadlines, including the May 1 Sunbiz annual report deadline for many entities.

  • A monthly review of your books and cash keeps small problems from becoming big ones.


Key Dates at a Glance


Here are the major deadlines for most calendar-year businesses in Florida:

Date

What's due

January 15

Fourth-quarter estimated tax payment for the prior year

January 31

W-2s and 1099-NECs; fourth-quarter payroll reports, including Florida reemployment tax

March 15

Calendar-year S corporation and partnership tax returns (or extensions); generally the deadline for an existing calendar year business to make a timely S corporation election effective for the current year.

April 1

File Florida's tangible personal property tax return by April 1 if required.

April 15

Individual and C corporation tax returns (or extensions); first-quarter estimated taxes; prior-year IRA and HSA contributions

May 1

Florida annual report on Sunbiz to avoid the $400 late fee

June 15

Second-quarter estimated taxes

September 15

Third-quarter estimated taxes; extended S corporation and partnership returns

October 15

Extended individual tax returns

December 31

Deadline for many year-end tax planning strategies and transactions


Dates can shift when they fall on a weekend or holiday. Check the IRS Tax Calendar for Businesses each year.


January: Close Out the Year


  • Review how last year actually finished compared to your goals.

  • Make your fourth-quarter estimated tax payment by January 15.

  • Send W-2s and 1099-NECs by January 31.

  • Gather documents for your tax return, and make sure your books are reconciled through December.


February to April: Tax Season


  • File your business return, or extend it if you need more time. Extensions give you more time to file, not to pay.

  • If you want S corp status this year, the election is generally due by March 15.

  • File Florida's tangible personal property return by April 1 if your business owns equipment.

  • Make any prior-year IRA or HSA contributions by April 15.

  • Pay your first-quarter estimated taxes by April 15.


May to June: Refresh Your Plan


  • Review your filed tax return. It can help you understand last year's income, deductions, tax liability, and potential planning opportunities for the current year.

  • File your Florida annual report by May 1. The state charges a $400 late fee after that date.

  • Set your estimated tax payments for the rest of the year.

  • Review your retirement savings, investments, and insurance.

  • Before hurricane season starts June 1, confirm your business insurance, emergency fund, and backup plan for your records.


July to September: Mid-Year Check


  • Project your taxes based on your actual results so far.

  • Compare your cash flow and profitability to your goals. If your business is profitable but short on cash, find out why now.

  • If you're an S corp, confirm your salary still reflects the work you do.

  • Pay your third-quarter estimated taxes by September 15.


October to December: Year-End Planning and Next Year's Goals


  • Look for tax-saving opportunities while there's still time to act, like timing equipment purchases or charitable gifts.

  • Review retirement plan contributions  and year-end payroll. Contribution and election deadlines vary by plan and contribution type, so confirm what needs to be completed before year-end.

  • Set your pay plan for next year.

  • Set 12-month goals and the key numbers you'll track.


Every Month


  • Reconcile your bank and credit card accounts.

  • Review your profit and loss statement, balance sheet, and cash position.

  • Move money into a separate account for taxes.

  • Track the key numbers that drive your business.


Staying on Track All Year
