What basic tax steps should a solo online seller take

I plan to sell a few digital products and run affiliate income as a one-person business.

What basic tax and business setup steps should I take as a beginner (registering as a sole proprietor vs LLC, invoicing, tracking income/expenses, basic records to keep, estimated tax payments)? Looking for practical starter actions I can complete in the first month.

Without knowing your country/state, it's going to be hard to give an answer that's accurate to your situation.

Assuming you're in the USA, since you're speaking of sole proprietorships, LLCs, and estimated tax payments, I'd do the following.

1. Start as a sole proprietor, unless your state, platform, accountant, etc, gives you a reason to form an LLC.
2. Get your federal EIN, state sales tax license, and any necessary state/county/town business licenses. Even if a platform allows you to use your SSN, using an EIN is far safer long-term.
3. Open a business checking account using the documents from steps 1 and 2.
4. Use an expense tracking program, or at least a spreadsheet.
5. Have a file to save all your business documents, receipts, statements, etc. One copy on your PC, one in a cloud backup, one copy in print.
6. Check sales tax, estimated tax, and local filing/payment rules for your jurisdiction, since this varies wildly from state to state.
7. Have an accountant review your first year tax return to make sure you aren't missing anything major.

You might consider starting a company in Hong Kong.

@Stavro pretty much covered the whole checklist already, not much to add there.

One thing I'd flag on the affiliate side specifically... keep your 1099s organized as they come in. Some networks send them, some don't, but you owe the tax either way so don't assume no form means no income to report. Had a mess with that my first year cause I figured a couple smaller payouts didn't count. They do.

On the LLC vs sole prop debate, for digital products and affiliate stuff with low startup risk I'd start as sole prop too. The liability protection people chase with an LLC matters more once you're dealing with contracts, employees, physical goods etc. You can always convert later once theres actual income to justify it.

The Hong Kong thing @payxgg mentioned... nah, way overkill for someone doing their first month of setup. That adds compliance headaches and costs that make zero sense until you're at a scale where it actually moves the needle, and even then its situational.

For estimated taxes, just set aside like 25-30% of every payment in a seperate account from day one. Way less painful than scrambling in April. The quarterly deadlines sneak up on you.
