Free weekly email · for US sole proprietors, LLCs and online sellers

The Radar

Every Tuesday: the business checking bonuses worth opening, the ones about to end, and the IRS dates coming up. Checked against the banks’ terms and irs.gov. Five minutes to read.

  • Bonuses with the fine print read for you. What you get, how much you must deposit and keep, and the date it ends.
  • Deadlines before they bite. Estimated taxes, 1099s, payroll forms and filing dates, a week ahead.
  • No noise. One email a week, no sponsored content in it, one click to leave.
What should it cover? (all three if you leave them as they are)

Who writes it

Greg Ciupek, founder of Aderlo and GAPLI

I run hosting and e-commerce businesses and have written about money since 2015. The Radar is the weekly summary of what MainStreetRadar checks every day: the banks’ terms, irs.gov and the IRS systems themselves. When I mention a company I run, I say so.

Questions

Before you sign up

How often will you email me?

Once a week, on Tuesday. If something urgent happens, such as a bonus ending early or the IRS postponing a deadline for a disaster area, it goes into the next issue or to the Telegram channel, not into an extra email.

Is it really free?

Yes. MainStreetRadar may earn from some links on the website in future, always labeled. The Radar itself has no sponsored content in it.

Is this financial advice?

No. It is information checked against the banks’ terms and irs.gov. MainStreetRadar is not a bank, a tax preparer or an investment adviser, is not affiliated with the IRS, and does not cover loans, insurance or investments.

What do you do with my email address?

We use it only to send The Radar. It is stored with your consent and the topics you chose, sent through our mailing system and Twilio SendGrid, and never sold or shared for marketing. Details are in the privacy policy.

How do I unsubscribe?

Every email has a one-click unsubscribe link. You can also email hello@mainstreetradar.com.

I have an LLC, not a sole proprietorship. Is it for me?

Yes. Choose the topics that fit: business checking bonuses and fees matter to every business type; estimated taxes and 1099 dates apply to sole proprietors and single-member LLCs, and we flag the dates that are only for partnerships, S corporations or employers.
