# When do I have to register for sales tax?

When your sales pass the line where you work.

**For**

See the month your sales pass the line, before it sneaks up on you.

**When**

Each month, while you’re under it

## Try it

4,000 a month against a 30,000 line: you pass it in month 8.

The month you pass it = the line ÷ sales a month, rounded down, plus one.

Watch the running total, not the month.

## Worked out

| Sales a month | A year | Pass it in |
| --- | --- | --- |
| 2,000 | 24,000 | Not this year |
| 3,000 | 36,000 | Month 11 |
| 4,000 | 48,000 | Month 8 |
| 6,000 | 72,000 | Month 6 |

## Easy to get wrong

- Watching one month, not the total.
- Finding out after you’ve passed it.
- No record of each month’s sales.
- Old invoices used after you register.
