# Married filing jointly vs separately calculator (2026)

This page is a one-income California $80,000 compare of married filing jointly versus married filing separately — not the married-versus-single page (single vs MFJ) and not the MFJ-only or MFS-only landings. Same wage, same state; only the filing status changes.

In 2026 the federal standard deduction is $32,200 for married filing jointly and $16,100 for married filing separately. Joint brackets are wider. Additional Medicare (0.9%) starts at $250,000 of FICA wages for MFJ and at $125,000 for MFS, so neither threshold hits this $80,000 sample.

The calculator starts on married filing jointly. Switch to married filing separately to see the same one-income California wage under MFS tables. A spouse’s separate wages are not entered; two-earner couples should raise gross or run two tabs. This is not a Form 1040 and not filing advice.

Use the dedicated MFJ and MFS pages when you want each status preloaded alone, or married vs single when the contrast is single against joint. Reviewed October 2, 2026.

## FAQ

No. Married vs single compares single to married filing jointly. This URL compares married filing jointly to married filing separately on one $80,000 California wage.

### Why does MFS look closer to single?

In 2026 the MFS federal standard deduction is $16,100 (same dollar as single) and additional Medicare starts at $125,000. Joint uses $32,200 and $250,000. Brackets still differ from single.

We do not say. This is a paycheck-style estimate only. Confirm a filing election with a tax preparer; withholding is not a Form 1040.
