Get your taxes done using TurboTax

When filing DC MFS (Married Filing Separately on the same return), you can allocate deductions to whichever spouse minimizes the combined tax. TurboTax usually pre-populates this based on who paid (if identified) or to maximize the lower bracket; it is generally safe to keep as is, or you can assign all deductions to the higher-earner to maximize savings.
