Common confusion points
Do I need an EIN if my spouse and I are filing for a rental real estate business?
The source states you do not *need* an EIN to make the election, but when might you require one?
You may need an EIN to file other returns, such as employment or excise tax returns.
→ Confirm this requirement based on your specific filings.
Where does the Capital Construction Fund (CCF) deduction go if I use Form 1040 (Schedule C)?
Instead of claiming it on Schedule C, how do you account for the CCF deduction?
Reduce the amount normally entered on Form 1040 or 1040-SR, line 15, by the deduction amount and enter 'CCF' next to line 15.
→ Check Pub. 595 for details.
When filling out Line D (EIN), should I use my SSN instead of an EIN?
Line D requires the EIN issued on Form SS-4; what if you don't have one?
Leave line D blank if you do not have an EIN.
→ Confirm this applies to your specific filing scenario.
